Charlie needs to be a regular feature. Great guy!

The bloke who runs this dyno is brilliant. Hilarious in every episode, Love his dry sense of humour.

Great to see Alex still around, and a great energy with both in this video!

Stock turbo should do around 1.0 bars. Just the fuel cut comes first before max boost around 0.8 bar on stock Map

Lads you can go to about 0.85-0.9 bar of boost with any turbo redblock on stock internals without any major impacts to longevity or reliability, it will impact how much you spend on fuel though. The ECU is quite good at adapting to the increased boost.

Nice to see another old 940 getting some, er, love. Please don't destroy it, I need spare bits for my 940 restoration! 😆

That engine is a B230FK, 135hp/230Nm from the factory. Only and I mean ONLY difference to the "B230FT is the wastegate at 0,3bar vs 0,5bar. Block, pistons, rods, cam, ECU program, injectors, exhaust, evarything else is 100% same. So just by adding boost you will gain 25-30hp IF the engine is otherwise somewhat up to spec. Then there is a Turbo+ version that takes 190hp out of the same B230FT/FK engine with an electronic boost controller. Again no other swapped parts than added electronic boost control instead of mechanical. This ups the boost to around 0,8bar if I recall correctly to achieve the 190hp. That is the maximum safe limit with stock parts. Most likely your restriction is the exhaust and specifically the cat if your power went that much down by fixing the precat exhaust leak. With ECU programming you can gain 235hp out of the same stock engine, BUT the intercooler is really close to blowing at 1bar of boost. There is also the limit for the injectors and turbo. The engine block itself is good for around 4-500hp with upgraded turbo, cam, intercooler and injectors and of course ECU and ignition module programming. I have a few of these making 350-525hp.

I love what you are all doing individually but it's great to see the band back together 👍🏾

I absolutely love the 700/900 series. Especially the turbo estates! These cars are so cheap to work on, live forever, and best of all RWD. Got my manual 745 with a 15g for only 1.5k a few years ago and have been obsessed since ❤

Great video, loving Charlie’s vibe and optimism 😂 cracking me up, kind of a James May vibe blunt yet he knows people will be laughing

Funny thing is that the B230FK engine (which is the unit used in this 940) is often turbo-swapped to a higher pressure unit from the earlier 740 Turbo. These engines are well built, and the stock internals can usually handle pressures up to 1.5 bar, and could produce over 200 HP without too much work needed. For Brick, the first step would be to replace the catalythic converter (those 100-cell racing ones are pretty good). This will ensure better exhaust flow. Then you can consider a turbo swap.

the dedication that went into this 🙌🙌🏻🙌🏼🙌🏽🙌🏾🙌🏿

I guess this is a LPT version. The HPT (high pressure turbo) got 165hp from the factory at 0.55 bar with an identical engine (the boost level is the only difference whatsoever). With the Turbo+ package you got around 190 at 0.8 bar. 0.8 bar + a good tune for both ECU:s should give around 200. You might have to upgrade the stock downpipe a bit, it's restrictive. I hope you give this thing some well deserved love :)

Good to see the short bloke back

As said below, a big TD04 and some good ECU chips, bigger MAF, bigger injectors, along with an 3inch exhaust system should see you to around 300+. Stock bottom end on the later redblocks is also good for 400 from what I've heard/seen too!

Next stop - eBay turbo and a sports cat! Should make Alex's wildly optimistic "240bhp" possible. Charlie's deadpan sarcasm/pessimism next to the lad's boundless enthusiasm was hilarious! 😄

So good to see Alex back wow, can’t lie I miss this infamous trio

It's good to see Alex is in a CT video again. Also good to see that Jack's taken on the presenter role like that.

The original turbo (Mitsubishi 13c) is good for around 1 bar off boost and just buy a adjustable wastegate actuator to make it a "serious installation". Though i recommend not to go above 0.8-0.9 bar without a chiptuning for both fuel and spark. PS: Sorry for bad english but i come from Sweden and me and my friends use to tune these cars.

I think you should open the cat and close wg completely. On 99 octane you might even be able to flip the cps connector to for earlier timing an more nm. These takes some beating fine.

loved this video, hope to see more of the car soon and hopefully ethan in the next video too, we need the trio back!

Charlie should be in every video from now on! His cynicism genuinely made me giggle!

Good to see Alex back and the guys getting on well. Hope this works out best for all 👍🏻

Charlie needs to be made part of the crew… he is pure joy to watch, so unique n so entertaining in his own way👍🏽👍🏽👍🏽

As much as Jack has been smashing the most recent videos is nice to see that Alex is still around :)

You should be able to get 1 bar no problem from the stock turbo. I ran a 940 without a wastegate and it peaked at around 1.5 bars. The engine can take about 1 bar without damage. The turbo+ models had 190hp on 0.9 bars from factory if i recall right. 1 bar should give about 180-200hp.

Love these types of videos making small mods and seeing what happens! Keep tinkering!

Finally good to hear someone who's not going on about putting high octane in absolutely everything. I'll run my LS on regular while watching some 17 year old with a 1997 micra using 99. Best car throttle vid in years though lads, informative but yet still straight to the point. Was hoping to see it with a hood exit on 10psi but there's always next time

Stock turbo can for sure make 1 bar. Tune kit here in sweden from BSR is with 0.8 bar wastgate that should make 205 hp at the crank instead of 135 hp stock

This really made me laugh. I'm aware that everyone does have the experience about redblocks. But thinking that 0.5bar of boost was enough to throw rods was the best part 😅 I've been working on redblocks for twenty years. And I do know some easy fix to get it going. With stock turbo it can do up to 185whp if the wastegate isn't cracked in the exhaust housing and it's very common. Leaking intercooler as well. A fresh intercooler can withstand up to 1 bar. Then it blows the seals. So tweak the ecu and aim for 1bar check the condition on turbo and intercooler then you are there. Depending on what kind of rods you got inte block (there are two different types) It can take up to 250whp on the wheels with a proper tune. Love these episodes! Keep em coming

Been binge watching the entire channel and my faves have been the adventures you guys go on :D I hope you can do something with this Volvo like it

Great video, guys. Like a previous commenter said, good to see Jack and Alex together, and interesting to see this dyno comparison.

Get Adjustable wastegate, Fuel/ignition chip and Performance air filter. Makes big different

I had one of these - the simplest gain is to space the actuator off the mounting with washers. keep adding until you hit fuel cut and then take one off. Made a significant difference, especially to low down torque.

Another enjoyable & interesting episode keep up the great work on the channel 🎥👍👍

The chemistry between everyone in these videos is at the same level with good old Top gear. Would be so nice to have friends like that!

Excited for part 3. Any idea when it will be???

These are sooo easy to make power with, you guys can sure make it look hard. My '97 2.3 LPT had a 2.5" Simons catback, a manual boost controller and the HPT cold air intake opened up in the airbox ( every box has a cold air intake in the fender you just have to open it up), running 0.7 bar. So basically just over HPT stock and it would put out 165-170 without even trying. Go get some t5 injectors and a bit more fuel and it can go up to 200 on the stock turbo. Get a early t16 t5 (because of the flange) and you can easily go past that toward 230. For stockish power mine was pretty quick, dead reliable, comfortable and fun to drive. Plus good steering angle and (on the last models) stock LSD. These are still so slept on in most parts of the world..

Spark plugs , clean the intake , port the heads 🙃

Great editing at the beginning after leaving The rolling road you somehow went from farnborough tech to invincible road not the other way around how it should have been 😂

Great video. This is getting me back into Car Throttle again!

I've never seen this channel, but somehow I've been presented with this vid of one of my favourite cars in *the world*..! 🤩

4:23 Under the tranny you can se that bar that goes from both Frame rails. In Sweden we call that "Ambulance Bar" because it was fitted on Ambulances and police cars to DRASTICLY Stiffen up the front end. Also i can guarantee you that you are probably lossing about 5hp in that dog shit old 90s AW70 gearbox. Swap a Manual m90 in and youll be on track.

15 years ago, I bought a 92 red turbo wagon. Ran and drove great. 130hp isn't bad considering they only made 160 new. The torque was 180 or 190 new. Great fun to slide around in the snow.

CarThrottle video on a wednesday?? Who cares, Love the channel guys!❤

B230FT has Bosch LH2,4. You need a customized tuning chip. The turbo is a Mitsubishi 13g. Change to a 15g, 16t, 18t or 19t and a WG of 1 or 1.2bar. Furthermore, you must change the cam from standard T to V, VX or A from another Volvo. Then you must have a wider exhaust, 2.5" or 3". For example, JT. Then the car will get 100 hp or more from the starting point you had. None of this will cost much as you will find used parts. 531 cylinder head can also advantageously be used. Good luck, looking forward to the next episode. Tore from Norway

I loved Charlie's energy in this video.

I was so fricking sad when Alex officially left CarThrottle But in reality he has had great success on he's own and he wasn't lying when he said he would keep popping up as a freelancer👏

Would have been nice to see how much it improved the on road driving experience after!

Charlies deadpanness in the whole of this is just the best, that man needs to go to hollywood!

We need more content with the brick!! MORE BOOSSTTT

Glad to see Alex back!

I love it! Part 2 coming soon hopefully??

Best rolling road in and indeed not in (because it is very much in Hampshire) Surrey. Charlie is always a good laugh. His Xmas opening time announcements are a highlight of the festive period. 😅

next: chinese turbo and more boost. I've seen some people doing huge power on chinese turbos tho

3 mins in and I’m here and Jack! Does Alex still have that Tina Turner cassette from the Mercedes-Benz mega spec video? If so please dm and post me it for my physical music collection, it would be much appreciated by me Alex, and I love Your work Lads, keep up the great work.🔥😎and 36 likes! Wow! I didn’t think people like me out there I thought I was hated by Society, anywho thanks Lads.👍🏿✊🏿🙏🏿🙌🏿

Great video, Charlie’s like an English tuning fork. Looking forward to the next episode. He loves pistons!

Jack next road trip move Auto Alex driver seat to its max settings then cut the handle off or remove the wiring if it's a electronic seat buddy 😄👌

What an optimistic attitude to bigger turbos! Go big, and WALK home! Looking forward to some fresh pistons blooming in the fading automn sun...

Loving the vibes guys, and Brick, always wanted one of these. Moreso than the gorgeous E40 at 5:35 (purely for the fact that I think the BMW should go to a more deserving driver!) Also, Charlie's humour hasn't changed, love it!

I run my 940 on 12psi and been like it for years. Never let me down and get absolutely thrashed. They geeza obviously don't know anything about a good old red block 💪🏻

1 bar boost is no problem on stock turbo that guy is full off shit. stock engine with bigger turbo and upgraded injektion is god for 300hp.. many have run with over 400hp on stock bottom

You can tune this ecu with ostrich and use bigger injectors. Change camshaft for a V or K camshaft and give it the boost. 1,2 bar down the bottom end is no problem with a 51mm turbo, I ran a standalone boost controller and 1,9 bar on stock motor (with cam). It can easily do 400hp with boost controller (watch boost at low rpms!)

It I’ll be the waste gate leaking boost, due to age it will be flappy and loose. Getting blown open basically.

11:03 "Ram air tube". I've done this with almost every car and truck I've owned in the last 20 years and it always makes a noticeable difference even with completely stock cars

I like Mr Optimistic. He was fun. Can we have Mr Optimistic on more often?

You know the video is good when it starts with a guy smacking a muffler with a hammer

Rust is lighter than carbonfibre

I saw Jack driving this on the M40 today. He looked so happy. 😊

Uvis Čevers?

I take it this is yet another ‘series’ that we’ll never see the end of

Those engines are bullet proof. Mine had an oil leak and I topped it up "when I felt like it", and it was *always* empty. They just keep going and going and going. My mounts were bad, and shifter was worn, and it ended up jumping into reverse under emergency braking sending the rear wheels spinning in a cloud of smoke. Drove home just fine! I highly recommend jamming it in reverse at 50kmph when you're done filming with it :D

Having grown up in farnborough it’s weird seeing it on a channel I love so much.

I have one and I've added a stronger spring to the waste gate. Boost pressure checked at 0.6 bar and it feels like 150+ bhp compared to 135 standard with 0.35 bar boost. Your findings back up my guess. Mine's in better nick too. Enjoy!!

Fascinating. My 1984 Alfasud Ti, with massive twin carbs, is two different animals on 95 or V Power. You can really feel the difference. I suspect with fuel injection and a turbo, the benefits are a bit sanitised. Yes, more Charlie, as someone else said. He’s like the Jack Dee of dyno runs 😂

in sweden the first thing we do when we buy a turbo brick is to t cross the wastegate hose and put a valve to trick the wastegate and raise the boost and press the fuel pressure regulator in a vice to raise the fuel pressure. dirt cheap for a good weekend of fun

The 13c turbo that comes in this is a little weak indeed but it is rather fun when it starts to pull because it's a proper spooly turbo, so you get really good acceleration I would say atleast from driving one of these cars myself, I would say getting your hands on a 19c turbo is probably better because it's the same look wise turbo in size but has a bigger turbine blade or maybe a T3 turbo which the Volvo 940 Turbo's came with, there is also a little neat trick you can do to get more air into the engine without removing the air filther box and replace it with a aftermarket pod filther if you wanna have a stock looking engine bay, which is to cut away the plate inside the bottom half air filther box to allow the air box to suck in more air which equals = more power, because that plate in the bottom half air filther box really restrict the air flow inside the air filther box so you really are killing the power on it if you don't remove it, and yes this trick has been tested on the Dyno by professionals, but no I think I would go for a T3 turbo and maybe a better turbo cam, injectors and the air filther box trick and then just go for it, my guess if you did all of those things would easily have 200hp maybe more, I know my brother has about 170 maybe 180hp in his 945 with the exact same engine and turbo.

Heres the thing about these old Volvo red block engines. They’re pretty much good to about 500 hp on stock internals. My mate took a 300k mile NA engine, threw a turbo on it, gave it 1.1 bars, went drifting an entire weekend and drove it 4 hours home. They don’t care 🤷🏼‍♂️ really interested in seeing a power Volvo build!

The ecu will not let you run more than about 15psi of boost without a tune, it hits boost cut. Love these videos though I hope you keep going with that car

I rememeber taking my r53 cooper s down there a few years ago to a group dyno session was a good day out, and Charlie and his team were great hosts!

Basically you got yourself an LPT, they run 5psi. The biggest turbo you usually want to go for is a holset HX40, if not there’s a Mitsubishi one you can fit, can’t remember the model but it’s a happy medium. All the best

The pistonrods can manage up to 1,5 bar of boost in those engines. Just add bigger injections and tunechip. Then you can make a 3" airflowmeter on 465cc injections to make a good mix 👍

Spark plugs at least, valve lash check, Injector cleaner in the tank minimum, a well needed catalyzer "regeneration" ;) , and a cheap oem or slightly bigger aliexpecial "bearing" spooly boy and you got some extra hrsprs there!

I have decided I really like jack and would love to see him on Alex’s channel

I own 2 740 models, a diesel with the original Audi turbo engine 1986 and a petrol 1989(no turbo) injection. Both cars are almost indestructible. I absolutely love them. (then again I am older than my cars) 😊

Shell, in general, is top-tier rated and if you're driving a vehicle that was always using poor quality off-brand station fuel over a few months the engine should clean out and perform better. V power or regular

Everyone likes a bit a Charlie now and then,one bar then two bar indulge in the back box if yer lucky enough orjust plainly fill a hole up front,from what i'v heard you get it all in Surrey lol,loving it brilliant show

I love videos like this, proppa cheap, shit car and make it go a bit quicker for the least cost possible. Reminds me of my youth. Good job lads 👍🏻

Stock snail (in good nick) SHOULD be able to hit 15psi with no issues. OLDER Garrett turbos used to be able to to @20psi or so. Internal CBV diaphragm may be toasted leaking boost...or you may be hitting stock ECU boost/fuel cut. Stock LPT 13C snails choke up on the top end and lose flow. Needs bigger turbo! 15G/19G/20G Slap a new snail on it and retest ASAP!!!

1 bar of boost is no problem with a functional turbo, but the "manual boost controller" is a no go. better to pay the extra dollar for a adjustable wastegate. Also the auto trans will suck some power out of it.

I ran 1,4bar of boost vx3 camshaft and chip for the fuelbox. Ran like a dream and didnt have any problems at all. I was running close in a race agains an s40 t5 stage 2+ with 272hp so just turn up the boost too about 1bar and straight pipe and you will have around 190hp

Round the corner from where I work, love seeing local roads on these videos.

Nice to see you back on the rolling road. Feels a while since you guys were there. Fun video.

A classic skandinavian tuning to these old volvos (obviously not a very reliable one) is to add a turbo from a volvo truck on these cars. I've been to sweden years ago and talked to people who build their rallye cars like that - but more for fun, since they often blew up. But it seems that some volvo truck turbo chargers even fit these older volvo cars, since volvo just evolved what they had and never changed screws, piping or even fittings.

the low budget vids are 🔥🐐

The stock td04-13c turbo in a working can do 1.1 bar along the needed fueling remap. That puts down 190-210hp. Upgrade to a TD05 series Mitsu or a Larger Garrett or a Holset. Change the intercooler and injectors and 250 is not a problem at all.

Mr. Alex, you need to learn that half of a bar is more than 10psi.. Cheers, great video man!

if you get the TD04 18c turbo and some green type R injectors from a v70 and change the camshaft and 2.5inc exhaust and a viking chip, 531 head with some mild porting you should be able to do around 1bar og boost and have around 300hp at the rear wheels. this is atleast what i have heard of as a 300whp upsett for these cars here in norway! :D and if the car has the m90 transmission be carefull with the 3rd gear cool to see people starting to play with these awesome old cars

You can hit 15psi before the computer will cut fuel. But after 10psi, without supporting mods you are blowing hot air. A popular mod is to use a 850 turbo...they are bigger so you'll get more lag but can push more air. I had a 740 with 2.5" high flow exhaust...no cat, larger injectors and custom intake and the manual boost controller set to 15psi. It had some good kick for a 300k mile car.

13:39 his deadpan delivery is the best
