Idiot.

Knowledge is power great video

facts

Bryan Dunn Lots of potential in the Camaro series. Lots of budget twin turbo kits available for the Small block Chevy engines. Superchargers are great in the Camaro as well.

Budget Boosting Agreed, I can pickup the piping, fmic, wastegate and bov, and a decent (non-ebay) turbo for a little over a grand. My problem would be tuning, my car uses the TPI setup from gm, so its run off of an ecm with a pretuned memcal. I think my next project is going to be a mkiii supra, although I haven't decided whether or not I like the 7m-gte platform more than the 1jz.

also where to get the air/fuel gauge?

starbattles1 Yes, I remember when I decided to go that route due to the stock fuel injection not handling the turbo set up very well. I went the blow through turbo route and I have liked that set up the best. I started with the Demon 650 blow through carb which was pretty good and eventually to the Quick fuel SS-650-BAN 4 barrel carburetor and I like it even more. I have the intake and exhaust manifolds off this Z car waiting for a custom twin turbo header which a friend of mine fabricated to fit two of my z cars which will fit any z from 1970-1983, all the L series inline sixes. It was fabricated to fit in these cars once the air conditioning compressor is removed and a few other things that are in the way for the twin turbo setup. To me no A/C is a small price to pay for a twin T04e powered L28 Z car. Once I get this new twin turbo header, I will get with my fabricator and he will start making them so we can sell them to others desiring twin turbo z cars. We will sell them on our budgetboosting ebay account where we currently sell our window stickers.

All Out Throttle awesome, boosted Mustangs fun to run. They are very popular at NMCA races in all classes. Would like to race that series in the future.

Austin Hermann Outstanding, do make sure you have the great assortment of gages to monitor all the engine perimeters that will change when adding boost to an already strong engine.

How is your project coming along?

@@matthewgraham2129 uhh......😅 not so good. The weather got bad so I had to stop working on it for like 2 months. We got thw motor and trans in, and got the motor fired up for thw first time without the turbos, and then went to move it undernits own power for the first time, but something is wrong with the trans, so it has to come back out

@@garymaddux2000 haha I get that completely I'm doing a single turbo on a sbc. Got the turbo next is blow through carb and all the rest of the parts. Turbo kit will be made of pure exhaust tubing haha

@@matthewgraham2129 I still need to get my turbo and blow through carb. Or I might go with an efi setup to make it simpler. For now, my headers just come up and point forward at where the radiator use to be lol.

@@garymaddux2000 haha I still have to gap the rings haha got the turbo engine all apart in my shop haha. The truck is under a snowbank lol. But I'm just throwing pretty much using every paycheck for parts haha. Easy to do when you are 18 lol. But let's of projects as it it

The carburetor is designed for boost blow thru. It is a quick fuel 650-BAN www.summitracing.com/parts/QFT-Q650-BAN. This carburetor with an arizona Z 4 bbl intake manifold will allow boost thru carb without complicated fuel injection systems. arizonazcar.com/engine

@@budgetboosting cool. Is there a difference between 650,750 or 950 other than price?

SuperDaveZilla I also first tried the fuel injection on my 79 and the fuel delivery had issues and that is what led to my using the blow through setup. I even ran the MAF sensor in the boost path just prior to the intake manifold so the MAF directly adjusted to boost but even that was not enough fuel delivery for boost and the low octane pump gas. Found that the blow through set up works well and will even work with the pump gas as long as the boost is not too high. Thank you for watching and look forward to some pictures of the Nissan 4x4 truck blow through when its done.

arthur clark Yes the older cars really benefit from turbocharging. I see many old monstrous twin turbo Camaros, Corvettes, Mustangs and many others blow through the traps and very high speeds and very low times at Top Gun Raceway.

back pressure is not considered from the point of bottom dead center but again the boast adds pressure the cylinder should test positive for vacuum if valve timing is correct likely in most of the older cars it's not as tight or correctly timed when it is the turbo is likely larger than normal

arthur clark At idle a turbo engine will see its normal vacuum, as load is added to the engine and boost increases, vacuum will become positive pressure so having the stock vacuum advance will not benefit the older vehicles. I removed the vacuum from my electronic distributor so it is a constant and no adjustment on vacuum. I also install a boost referenced fuel pressure regulator that ensures fuel pressure rises as boost rises. When much larger turbochargers are installed, usable boost will take longer to build up and directly reflect negative vacuum and boost pressures. One way valves or breathers should be installed to ensure boost does not pressurize the valve covers or engine block. Lots of things to consider when turbocharging a non-turbo car. Its quite the adventure though.

Bryant Arnold Thank you, Its great to have people that appreciate our work.

You could have an adapter flange made with a T3 turbo flange and a custom made bolt on adapter for your intake manifold to run a holley style blow through carb.

Ghosty wun Thank you for the comments and thank you for watching. Happy boosting !

Terry Lewis Nice, lots of aftermarket support for fox body mustangs and many have been successfully turbocharged to very monstrous proportions. I really like the foxbody and its potential. Thank you for watching. I made 4 new videos and two of them are related to turbo conversions.

Most def! Thanks again

all done? how did it run?

Outstanding, thank you, it is our goal to share what we have learned and see others accomplish this great technique on their fun cars.

Like z cars, even like them more turbocharged and carburated.

Budget Boosting I believe I found your website with the old HKS triple deuce blow through turbo kit. I have always liked that kit ever since I saw it in Japan on an S130z with twin TD06 turbochargers on a 3.1 stroker. That car was wicked and that kit is severely hard to find. In the states Jim Cook Racing used to sell the Cartech triple weber side draft complete kit including a T04 turbocharger, external wastegates, intercooler and all the tubing and bolt ups necessary for installation for around $3500. If only those complete kits were still for sale, that company would make a fortune since there are many old Z enthusiests than there were then..... I like the HKS set up you installed, since you were running rich, a much larger turbocharger would fix that, somewhere around a T70 with ball bearing, 15-20 lbs of boost, 100 octane fuel and you would be golden.

No worries man, good to hear the video's are having real world applications to people.

KFLY67 Thank you, I had instructing and facilitating experience teaching my fellow military personnel during various times in my 21 year career.

Its an older video

+Budget Boosting do you have a video with a carburetor enclosure

the blow through carburetor video has a 4 barrel carburetor enclosure. It is not a large enclosure but designed for blow through application.

nica8487 Thank you for your comments and watching, glad you like them. We will continue.

corsomike1 One, I never chop the throttle, Two, Turbochargers made strong with good quality, have no issues, they are designed to deal with great extreme forces acted upon them, if not, they are not good turbochargers. I have even run low costing ebay turbochargers without blow off valves such in the Red 300zx turbo, no issues, great throttle response. The black buick has no throttle response issues, in fact its a hard charger on the throttle and of course it has no blow off valve and never did from the factory either. Three, My throttle plate is never all the way closed, most have spaces on the bottom to allow air or boost to retain idle characteristics, so most throttle plates are never completely closed.

Budget Boosting yep fatiguing the metal of the compressor isn't bad and garret ,mitsubishi, holset are not quality turbochargers ? when you stall the compressor at 100,000 or higher rpm the vanes flex , ungulate and twist . your right that isn't bad . and yes back in the day they didn't use bypass or blow off valves nor did they use inter-coolers but they learned from that haven't they just because it can be done doesn't mean it should and of course the throttle plate stays open a little or the engine would die ( come on ) you just don't get it ... and probably never will .

corsomike1 The 1987 buick had a garrett intercooler from the factory. I am not against blow off valves, I believe they are not always necessary. Some turbochargers such as the small ball bearing high spinning type can benefit from a blow off valve. The large big single turbochargers such as the T88-34D that I ran on my R32 Skyline GT-R did not benefit from a blow off valve, and I do not run them in that big single set up. So there are times for the blow off valve and times I do not run the blow off valve. The bottom line is they are not always needed, some set ups good, some set ups not so good. Like I have said time and time again, it is the tuner's choice and I do not knock any tuner for using them or not using them. I have always and still believe that they are not 100% necessary for every single turbocharger setup across the board, just some of them. I do get it but they do have their place and their place is in some turbo set ups, not all of them. I pick and choose what set ups of mine get blow off valves and the ones that do not. That is called specific tuning for specific types of acceleration depending on what you will do with your turbocharged car or truck. Most turbo failures occur due to 1. not using an aircleaner, which destroys the compressor and turbine, 2. Not changing oil often since the oil is shared with the engine. 3. Running the turbocharger really hard at high temperatures without giving it sufficient cool down at idle before shutting engine off. 4. Engine running too lean with cheap low octane fuel which heats turbocharger too hot and elongates turbine and compressor blades which will fail. 5. Too much or not enough oil flow in turbo bearings which will lead it to fail. I have run many Garrett, Holset and Mitsubishi TD series turbines without any issues with or without blow off valves. Its all about how well everything works together and how well the set up is taken care of that determines how long turbochargers will last. My 1987 Buick Turbo T Garrett turbocharger lasted 28 years and the car was mechanically well cared for. There is no almighty answer for every turbo setup for every vehicle so that means that blow off valves are NOT needed for every single turbo set up.

Sorry I'm late to the party, but you can use a standard carb in two ways. Firstly isn't so easy (unless it's fairly commonly done with that model of carb for example SU carbs), seal up any vents/throttle shafts etc and find a way of venting the float bowl as well as being able to pressurise it on boost. *Second & much easier* but less tidy maybe is if you build the whole carb into a plenum chamber. This means the whole carb inside and out sees boost and thus no excess pressure is put on it. You then only need to seal up the point the throttle cable and fuel line enter, just make sure to use a linear fuel pressure regulator with the plenum set up so that your fuel pressure stays at the correct level relative to the boost rather than the boost overcoming the fuel pressure causing the car to lean out.

How the hell are you going to say building a boost box for a carb is easier than $50 worth of mods that anyone can do in a day to any Holley carb easier ? To the original poster if you haven't already bought a blow through there's a right up by hanger18. Not everything listed is necessary unless your making 18psi plus. I have built 3 Holley blow through carbs for around $50 each. But the most mine have seen is 15psi.

no

johanijohani yes the ones that have the adjustable spring are the best type.

dandil Watch our blow off valve the truth video. Then if you still desire to make a comment, make your comment about blow off valves on that video not the Blow through Carburator video. Thanks

all it does it slightly wear the thrust plate in the turbo core and to tell is when a turbo shaft can be pushed back and forth(towards each turbine) this test is not the up and down play that ever knob talks about there is a test to check for play up and down on the compressor wheel and that is to hold the nut and pull up and down(towards each side/top and bottom of the cold side/compressor housing) however every turbo new or old has play this is normal and this is because there is very little oil in it when you add oil this play will go to almost nothing as the oil and its pressure closes the gap a good turbo will have some play but they should not hit the housing if so they are no good in worse case it will bend or snap off blades/fins of the wheels bovs with out them you can worst case is they snap the shaft(snap the compressor or turbine wheel off) this hardly happens but does happen

Bottom line....you don't HAVE TO have 1.....but, it is a little more wear on the turbo on low boost systems. Now on systems with more (fun stuff) boost it WILL damage the turbo a lot faster then you'd like it to and cutting the life of it by a fair amount. But your right you don't have to have 1 if u can't or don't wanna afford to put 1 in but it is always recommend! Not to mention if your running a lot of boost and no waste valve it can blow something up. Seen it first hand lol its kinds like wearing a seat belt....do you have to wear 1 to drive...no, and u may go forever without an accident where u needed to be wearing 1 or u could never have an accident, or....you could go out on your first drive and bam ...should've put that belt on I guess lol....everyone loves to gamble right???? Would I put 1 on? Yes....would I drive mine here and there until I could get 1 put on? Yes...long term you should have 1 installed, the cons just outweigh the pros no matter the odds

@@jjmccloud No man! Didn't you listen to the video? He says it just, "dissipates". LMFAO!!!! 🤣🤣🤣😋

You dont have to have it just like you dont have to have a intercooler but it makes no sense not to have. Especially when you can buy one used for nothing.

Move on over man the more the merrier

Kevin Williams That should be a beast, Summit sells great Quick fuel blow through SS-650-BAN carb.

Awesome. Thanks

@@KevinWilliams-px6il it will be an awesome grenade.take lots of video when you run it/blow it up

Ahmed Nabil You can install your blow off valve anywhere on turbo compressor discharge or as I did. The important part is you pick a good place where it fits well. Fuel air mixture can be done by the carburetor jetting process and by way of a boost referenced fuel pressure regulator, I made videos on both those subjects you can watch.

Budget Boosting yea i did watched all of the videos related to the questions i've asked i recently made the oil connection ( connector and a return to the oil pan ) tomorrow i will fit the turbo compressor to the manifold as for the AFR i will get a gauge to measure the lean and rich process and start jetting it until it get the suitable ratio i got the fuel jets as the following as a standard factory 115 for 1st gate which is primary and 125 for the secondary throttle .. i replaced the secondary with 135 jet is there anything else i can do to my carburetor ? and thx for replying ^_^

Ray Dolinger Right, they didn't grow up seeing turbo powered engines evolve like we did. From the 1965 Chevy Covair,H-6 draw through turbo, the 1978 Buick Sport Coupe Regal 3.8 draw through turbo V6, the 1980 Pontiac Trans Am Turbo 4.9 turbo, draw through V-8, 1980-1983 Datsun/Nissan 280zx turbo 2.8 straight six fuel injected turbo, 1984-1988 Nissan 300zx 3.0 turbo V-6, and many more. All those cars never had blow off valves and no turbo car I have seen had a blow off valve from the factory. A lot of them had relief valves to prevent overboosting engines when the internal wastegate rubber tubing disconnected or wastegate failure. Kids these days do not know the history of turbocharging, how it evolved into what it is today. Thank you again for watching.

Its not marketing it's a fact if your running less than 10psi then no a BOV may not absolutely necssary but get above 12psi and compressor stall is real and damages the compressor wheel over time. I've been involved since the days when turbos were all draw thru. I remember seeing a 68 camaro w/468 running twins drawing thru a 1050 dominator make god like power 850 on the dyno. but it was a mess to drive and a hot house flower only good? for drag racing turbo lag was measured in secounds as in 5 then it spooled like a light switch nothing, nothing ,OMG. It was a waste land none knew anything few guys running Offys at indy and some old vets from WWII with fighter plane experience. One was to small the other to big same for the turbos. It was all cut and paste with crutches and no cheap welders migs cost a couple of K tig was just not an option, Since they were draw thru one back fire could destroy everything or even kill you all the intake plumbing back to the intake inlet was filled with combustable mix big boom sharpnel and other pcs flying everywhere and direction.

roger depew I have a blow off valve on the Blow through carbureted 280zx car and it runs fine. I do not have one on my fuel injected 300zx turbo, using a budget friendly TO4e ebay turbocharger and run around 18 psi daily driving, runs great and reliable. Turbochargers that fail are for issues not related to lack of blow off valve use. They usually fail due to foreign object damage, no air cleaner, dirty contaminated or poor oil change schedule, not allowing the car to idle down for several minutes to allow hot oil in the bearings to cool down before shutdown. Most people just drive the car hard, avoid preventative maintenance, park and shut off the engine and wonder why their turbochargers fail. Many companies do capitalize from these failures and conveniently relate them to the lack of blow off valve use. Draw through turbocharging, you cannot reasonably use a blow off valve due to fuel and air released in the engine compartment when the valve opens. Honestly, a well made turbocharger is built to withstand very extreme heat and pressure forces and one that fails for some surging is really not a well built turbocharger. The 1984 though 1987 Buick GNX, Grand National, T-type series turbo regals boosted 15 psi stock and many increased the boost much higher. None of them ever had blow off valves from the factory and very few ever installed them or even heard of them in the 80's. I know of many people today still running the original 27 plus year old turbo Buicks with the original Garrett turbochargers still laying down competitive drag times and great daily driving cars as well. Many Nissan and Toyota turbo cars I tuned, drove and enjoyed in Japan did not have factory blow off valves in their cars and I drove them hard and they performed great and reliably. The above is the reason I made blow off valves, the truth video. I am one that does not believe the hype about blow off valves, I have had them on some cars, and not used them on others and honestly had no genuine need to. Its always up to the owner and the tuner of the engine to make that decision.

bullshit. were do you people get your info from smh

A turbo charger will never dead stop from lack of a blow off valve. It will gradually stop due to reduced exhaust flow when accelerator is released, the shaft between turbine and compressor rotors is direct, and they spin at exactly the same speed. Even at idle, the turbine and compressor spin, so there is no way unless the bearings fail that the turbine would just dead stop.

Yes it can. Its not about the exhaust. When the throttle closes coming down from high engine RPM, the boost from the turbo to the throttle shaft is trapped and the pressure spikes, with nowhere to go- causing extreme pressure in the inlet tubing before the carb. I have actually seen the turbine stop when a blowoff valve failed on my sons drag car, the Hyper Bug. Look up the car on KZfaq.

In Japan where I used to own a 1992 Nissan Skyline R32 GTR I had a big single T88-34d turbocharger with external wastegate running 28 lbs of boost, no blow off valve for several years. Most tuners in Japan with large big single turbochargers do not use blow off valves. Smaller ball bearing turbochargers I can see running one to slow one down more gradually. There are many factors involved for a turbocharger to fail. If it locked up, it is due to a bearing failure or balance problem leading to the blades striking the housing and seizing. When tuning any engine, throttle plate needs to be open enough for decent idle which spins the turbine. When extreme forces are exerted to a turbocharger, heat, lack of cool oil, etc., turbochargers can fail, I have never seen one fail strictly because of a blowoff valve, there are always other factors other than just the valve that made it fail. I have even run cheap ebay turbochargers for up to 8 years without a blow off valve without any failures. That says a lot. Buick Grand Nationals run turbochargers from the factory without blow off valves and I still have the 30 year old turbocharger that was removed in good working order. It is your opinion but I do not believe it and nobody will convince me otherwise.

Zackary Wilson I look forward to seeing the results, it will be quite monstrous.

Fuck the old cars just a sec tho lol get a brand new car get a new old carbed engine swap it out and chuck this system on it and confuse every person my age or younger

johanijohani This particular engine in this video does have a blow off valve. My red 300zx turbo, and Buick Regal Turbo T do not have blow off valves. Thanks for watching.
