Love that people are working with The forgotten but not un loved 3.8 V6. The big issue here as we all know is the glass transmission. In the day when I had my MKIII VR6 Jetta(n/a highly modded cams, BVH/P&P, intake manifold, etc.)I always thought The GTP was a beast.

Those 3800's can take some abuse, but need some mods to support higher horsepower builds. ZZPerformance sells a modified oil pump spring that helps keep the oil pressure up. Ring gaps are too tight from the factory and need to be opened up to support higher boost levels. Throw on an intercooler and the motors make great power. I run solid 12's with mine on pump gas and a conservative tune so I don't blow the transmission.

Richard, thanks for continuing to explore options on the 3800 engine. With how far our community has pushed them, it's fun to see some comparisons of various things at different levels.

That rising boost curve after 5000 rpm might mean you need some ported heads along with more cam. Looking forward to seeing the water or meth injection results!

Thank you for talking about these motors. They are great.

All these videos and the priceless info in them i love it. These other guys engines even better, and even better still you're testing using E85, water meth and mods that drop boost/charge temps but up in output its like dyno video heaven. keep em coming.

Best show yet, #Rich ... Best sounding 3800 that I've ever heard, even though there was more horse power to be had. Can't wait see you break 400 horses with basically this same setup - no turbo. 💚

Really cool video. Appreciate all of the editing, dyno of engine and how you showed how you changed the cam yourself. Keep it up!

Richard, you should check out some of our Aussie builds. Quite a few 400+whp setups and even one that has cracked the 500whp mark on a gen3 m90. Even got a guy pushing close to 600whp from memory with a larger yt 2300 blower. Hit up brushworks slick sixes for their cam and ported blower. Best in Australia with our l67s

Finally I’ve been waiting for this really hoping for a Big Bang

Richard, You have got to rebuild that motor and port the blower and heads. That would be cool to see.

As always I learned a lot , one thing for certain I'm going to wrap the longtube headers on my heads , cam intake LS1 even though it is na , it will be fun to compare before & after temps , thanks Richard......

Oh, Richard. the Fiero and gm front wheel drive are going to love you for this...

Always have been a fan of the 3800. They make good power and are reliable. If I get my hands on something that needs a GM v6 swap I will get my hands on one. I used to want an intrigue with a gtp swap, I feel like that would make an awesome sleeper while still being a comfortable sedan. I also really like my snow wmi kit. I have the "stage 2.5" on 2 of my turbo cars. One of them is mounted on the outlet of the intercooler and gets to ambient and sometimes under. Too bad the 3800 didn't hold up for more testing.

As a guy that messes with these in Australia, ported heads are where you'll pick up the most power, stock heads run out of na flow at 180whp

I'm happy with this . Great engine .

Be nice, to see this engine, with hand porting to heads , intake and supercharger.

When you get the heads off, get the guide posts machined down so you can get .600 lift in there. A cam in the 230s with .580ish lift will net some decent gains. Especially turbo.

Love the shirt Richard!

Love thisss!! 🤘🏻🤘🏻🤘🏻

I want a racing cup where everyone puts these in some crazy f1 looking kit cars

This is all good information for me. I need to know this.

Richard -very cool t-shirt

great vid no fault on that , shows the useral a mild cam and longtube headers goes a long way ;)

I bought that same valve compressor tool about 20 yrs ago

I come across these SC's about once a year at my pick and pull and always think I'm getting something crazy for the money ($50) but then I end up getting rid of them a few months later for like $80-100 since I don't have any small displacement motors

Mace Engineering makes a stroker kit for the L32/L67. It would be interesting to see how that does. Increases displacement to 4.2L.

Definitely excited to see the water meth testing 👍

Running 15psi using a 2.9 pulley. Had to add a intercooler and ice box. I always tell people if they race a supercharged 3800 car and lose just keep trying cause the more heat the slower they get. The second run is never as fast as the first. One hit wonder engines, atleast with the non intercooled m90. GM never shoulda let these engines leave non intercooled.

Them 3.8s are sleepers!! My brothers and I bought a gtp off the auction and we have it on a 150shot and e85 and that thing is unexpected on the streets

Need to do one of these videos with the ford 4.2l v6

Would love to see a test of a w2a intercooler.

Can you do a test on a stock S/C 3800 with the rocker arm upgrade?

If you can drop those IAT's can you throw more timing at it and drop those EGT's even further? Man, I was worried about my blower car seeing 120°F IAT but after seeing this I am quite pleased haha.

😆 I have jaws on the TV but I open my phone to richard with that shirt

One of these in a chevette would be fun

Excited for the water meth testing

These engines are good gm should have just built them up with more power. From factory

This needs to go into the Nova

I wasn't expecting such a great increase in power with just a cam swap, especially one with only 210/220 duration. The factory cam must really stink.

Omg! I... I.. just dont know what to say!!? - back to drooling!.

Since buying an l67 I’ve figured you don’t buy them for power unless you’re ready to spend more than what it would cost to just block off the pulley and run a turbo through it

Great video Richard! Any correlation between ignition timing and EGTs. I understand the timing was tuned for max HP, however I question if more timing (30deg+) would reduce the EGTs/glowing headers. Thank you.

3800 series best motor ❤

I have the bottom port and m90 supercharger my 3800 is a n/a do i need the supercharged heads with pcm or just heads

Sounds like cheap fun to me! Wrecking yards are full of these engines and can be had for a song and dance.

Could you run LS rockers on the 3800? If I’m right the LS has a better ratio like 1.6 rather than 1.5

That comp cam is similar to the BTR torque cam. It should have been installed factory.

I wonder if you could put this supercharger one the 292?

I'd like to see you put all that supercharger kit on a na 3800 and see their max potential

Hi 👋 👋 👋 👋 Richard anyway I thought the test went well. But I was wondering if you would of used a cam bushing so you could advance the cam 12 degrees. And if it is advanced to much you can go into the programming of the factory complex and adjust it. This is only an idea only. I have no idea if it would work. Oh can't wait until you do the next test on that engine thanks Ray

The thing I would really like to know is how this would affect MPG. Doing dyno work is always cool to see the results but we all know, we don't run our engines at WOT under max load all the time. Yes getting more peak HP and TQ makes us smile and maybe something else un mentionable but we need to be emissions minded, and mileage minded as well. Then there is the issue of dependability also as this video brings out. Who wants or can deal with knocking bearings and cranks out frequently. For Richard to be able to just go out and source another engine to grenade is fine for him I guess but eventually it will come when they are not so easy to find, even though they were produced along the comparison of the VW Beetle.

any suggestions for a non-boosted 3800? loved the video!!

@Richard, would you be willing to try upgrading the bearings in the block that spun one? I was part of a group of dudes in high school who were really into these engines and we found the stock crank bearings to be a limiting factor. If I remember correctly, we were using Clevites.

Richard, I watched a video awhile back and you made me see the light. It was the clone gt45 on a 302....which I bought. Towards the end you said stop worrying and do it. Well, I'm doing it. I still have questions though. My windsor already has Icon pistons, eagle rods, it's probably just getting skip white heads this time around. I plan to tear it back down and add gap. It is currently 10.5:1 if I remember correctly and I'd like to think cam choice would play a part in keeping it alive (duration, cyl pressure etc). I have two roller cams on the shelf, Recommendation?

Great video would like to see the gains of 1.9 rockers on stock cam if would get you 20hp gain as cam gets you 40hp ?

How much does l32 supercharger on l67 (240hp) add?

Why did they ditch the turbo for the sc, since the latter has no ic. Sc's more $$$ I'd imagine too

You got to get here quick when the vid drops if you wanna be #1.

I know this is a late ? But I always wondered what's stopping someone from turning a smaller pulley on the lathe 😅 😊

My Supercharged 2004 Buick Park avenue Ultra needs 93 to 99 no ethanol blended fuel. My owners manual states that any ethanol blended gas can damage to the block and supercharger and no regular 87 as it will knock heavy.

Hey Richard. I was wondering if it would be possible to stroke the 3.8. Platform? When I was attending wyotech in 2013, I was really wanting to see if a gm 3.8 v6 could be stroked. We did some math and found out that with a .30 over bore. A cam and crank from a 4.3 v6 it could be possible. Then I wanted to see if it would be possible to twin turbo the engine. Let me know if you could attempt this or crunch the numbers and let me know if it's possible.

Water-meth tests will be awesome, I'm curious for the same reasons I still think you should reference boost from the intake manifold! Should let the turbo sing more

Would be good to try a more aggresive cam. The life seems a little low and I'm the intake duration could be higher. Id love to see a 230 230 114 @ 550 lift

Why not run f-body headers??

Hi Richard. do you mind if I pick your brain. you've inspired me to do a budget turbo project. I'm using a ford laser with a 1.6L Mazda ZMDE engine and an eBay T25 turbo. it has a 2" compressor outlet. most of the cheaper intercooler and piping are 2.5" , would there be a problem using a 2- 2.5" silicone adaptor and 2.5 intercooler and piping? Thank mate. Richard from Australia.

Mr Holdener,I need your help .I'm trying to maximize HP with the parts I have . Need to know what heads to add to mix for total maximization. This is what I have. (Elgin - 1840p / Fast lsxr -102 , timing chain , smaller crank pully ,high vol oil pump. Headers longtube .I'm looking to match what I all ready brought to a great pair of heads. What do you recommend ? ( going in an Corvette ls1 2000 frc. Manual) Thanks again for your time 🙏.

So am I good with my setup or should I drop pulley size on my 3800sc intercooled with zzp xp hot cam. Stock heads, 130 springs, ls7 lifters, on a 3.4 pulley the car feels great but wondering if it's a huge difference to goto a 3.2 pulley or am I staying in a good curve at 3. 4 pulley

I never knew these were pushrod

How aggressive of a cam can be ran while retaining streetability? Do plan on doing a test with the comp cam and compound boost? Why can a VW 4 cylinder produce 1200 hp, but this V6 only makes 1/3 at 400 hp?

Will any of work on an 4.3

What did blowing boost through that charger do id like to see boost gauges in diffent spots like before and after the blower

Richard you need to do a Ford 3.8 supercharged v6 from the thunderbird sc vs gm 3.8 supercharged v6

I was interested in these motors a few years back for an s10 swap. Went ls

@ Richard Holdener/ what is the L32/L67 mean. What if you even the number 67/67

Egts are just a number

Yokes. 1437f is cooking. I get out of it at 1350 on my diesel and it's iron headed.

Howdy Richard. Not supercharged, or turboed. What extreme cam upgrade would you recommend? Thanks!

can i put a 3800 supercharged series 3 motor in my 3800 series 2 non supercharged grand prix do i have to change anything

! Hey are there any high twist helix rotor packs to install into these M90 blowers? Do you know what I mean?

Any chance you could try a set of 1.9 rockers with this cam?

I would love to see those same cam specs on a 110-112 maybe a touch more duration

Can you put this supercharger on a 2000 ls1 ? This motor was a corvette motor built for twin- turbos I took off the turbos because they needed new seals everything else still on the car.

I'm curious.... I ran a series 2 1998 gtp with a ported gen 5 blower on a 2" pulley running 21psi . Upgraded valve springs , short stack intercooler, comp xp cam , ported heads throttle body, headers and cai and custom tuned ecu..... plus a fully built trans to handle the power . Can you do a similar test have pic of my build but don't know how to share it.... total animal lots of fun

What’s the biggest blower you can swap onto those motors?

what should ring gap be with 14psi boost? plz

Hi I have a L67 in a Fiero it’s a fully built engine. I have an inter cooler and I’m using the North Star tb. I have a 3.6 pully we did a tune I got 345 whp my tuner did not do any timing. When I got home I saw we are at 12 degrees in all rpm range. I have the hp tuner set up. I want to change the pully to the 2.8 and re tune with timing. Also I am running E85. My tuner said the IAT should be relocated from the TB to the manifold. I guess I have to drill the manifold. Is that what you did ? And do I use the North Star IAT in the manifold so I make sure I have the same values and leave the other one in the TB just unplugged ?

That combo would have been nice in my Buick ultra. Or my Grand Prix. Too bad it didn’t holdup

So you stormy have to gap rings for the n/a? And don't have to change Connecting rod?

aren't these 3800 motors configured as front wheel drive? Can you use these on a RWD car?

Richard is the engine making less boost or just showing less PSIG?

The testing for this 3800 kinda dropped off. Been almost a year now lol. The chat across some of the 3800 groups were wondering what happened. Some were expecting a lot just because the LS stuff does, but I understand that's unrealistic to

Why not do some new bearings and rings, with a dinglebary hone, to a good junkyard motor.

I see the problem, you are missing two pipes on your headers, wait, heck, you completely missing two cylinders! Haha!!

I wish Richard was my neighbor, or at least a good friend

What pound rating valve springs did you use?

You know it's going to be a baby cam when the heads don't come off a 3800 hahaha.

Richard, I noticed when you showed the charts for the boost curves, and the fluid air temps, that in the chart titles it said "comp cam SC water meth base22". What was this about? I didn't hear anything in this video of the mention of water meth being used. Although in a previous video I remember hearing you wanted to test water meth injection into the blower. Was this a typo in this particular chart, or? I can't imagine charge temps ever reaching that high while spraying water methanol, unless your weren't spraying enough.

i looked into doing this to a 3800 years ago and came to the conclusion the transmission can not handle that kind power for any length of time. the only path to fix the issue is to modify a FWD Cadillac transmission to replace the 4T65-HD transmission.

At what point do you need to machine the valve guides for extra lift?
