Did you have any issues regulating boost with this manifold? My 38mm gate seems to have issue with it now that i opened the exhaust.

[@BoostBrothersGarage]

Not so far. We have run up to 22psi and didn’t see any issues. We are using an electronic boost controller as well though.

[@Addiesarkisian]

Might be valve float, boost pushing the valves open , maybe some upgraded springs

[@sabornight777]

awesome video! is this with the same 550cc injectors as the NA car and are u using the IE fuel rail on the turbo car?

[@BoostBrothersGarage]

Thanks! The NA car was running factory injectors. We’ve got 630’s on this car. I don’t think 550’s would be enough. It is the IE rail, mainly so we could bring the fuel line in from the back. It’s a nice piece!

[@DriftaholiC]

Bigger wastegate can also improve flow on the top end. Back in the 80's F1 cars would run multiple huge gates to allow top end flow without sacrificing spool time

[@BoostBrothersGarage]

Good point. I would think a 38mm would be big enough but something to look into.

[@labmancdn]

@@BoostBrothersGarage love the build. For verification of turbine restriction add a pressure gauge on the exhaust manifold just before turbo. Pressure preferably 0.75 to 1x boost, if your in that zone then not an issue. If your running 1.25 to 1.5x then bigger waste gate or turbine for sure. HP Academy shows a nice EMP setup rather than me detailing here.

[@EschatologyAndUs]

@@BoostBrothersGarage yeah I'm waiting on a swap guide to build the confidence to try and do it myself

[@ThomasJoseph315]

I feel like I've been justified about my thoughts of O7K vs LS in this video. Here's the thing. You can get the same amount of power from an LS with a cam and a tune as was just made in the 07K. And here's the bonus thing.. If you get an aluminum block, you are probably about the same weight as the O7K, maybe even lighter because no turbo, piping etc. Now here is the next stunning factor. dollar per dollar 07K vs LS... the LS wins hands down. O7K's work, but at the end of the day, you are putting in a lot more money for parts for the same amount of power and weight. Plus you are dealing with boutique parts suppliers vs going to every auto parts store on the planet and buying what you need which makes road tripping a lot more fun with less stress.

[@davidottobre188]

Unfortunately, when it comes time to track a car on a road course, the LS isn’t nearly as good in practice as it is on paper. To make them live, most people end up having to go dry sump, or wish they would have after several motors. This car had an LS, and it became such a hassle trying to make it live, they changed course and developed this kit. LS swaps are also pointless in these cars, why not just buy a corvette? It’ll be cheaper, easier, and faster.

[@ggauth]

When are you going to get the holset on your 944? Shouldn't have the same top end issues???

[@BoostBrothersGarage]

Not sure yet? We may be building the engine to handle a much larger turbo. I have an extra engine I am trying to talk PE into letting me strap to the engine dyno. If I can make that happen i want to do a number of tests, to destruction, and with different turbos

[@p0intdk]

Dont know if it was said anywhere but is this on pump-gas? Edit: How big was the housing on the Garret turbo also?

[@justinjerome6950]

I know that this car is not build for drag racing, but will you guys ever take it down the 1/4 mile?

[@BoostBrothersGarage]

We are going to some 60-130 and half mile testing. The transaxles really don’t like hard launches so 1/8 and 1/4 mile is tough. Trap speed would be nice to see though.

22lbs of boost?? It wont be long before you're looking for another engine for that car. Max I would run is about 14 lbs which should yeild about 350 hp and 275 ftlbs of torque. From an engine logevity standpoint shifting at 6600 is PERFECT for this engine JMHO, especially if you plan on using this as a track car. PS was anything done with the timing???

Hey, I only JUST started watching your videos on the 944 with the 0k7 swap/turbo build. I am really curious what trans you are running. I have an '83 bmw. I was planning on doing an m3 swap on, but I am loving the 0k7 swap and think I might go that way, SO yea, I was just wondering what trans set up you had so I can look into it further for my build. Thanks! And keep up the awesome work!

[@BoostBrothersGarage]

Hey there, thanks for stopping by! On this swap we are running the factory transmission but it is a rear mounted transaxle. For your application you would most likely want to run an Audi 01E transmission, although we are developing the components to run a Ford T5 behind the 07K as well.

[@pacoflyer]

@@BoostBrothersGarage Would the T56 be too big? I like 6 gears. Does the 01E have issues since its got the drive shaft inputs on the side?

[@BoostBrothersGarage]

@@pacoflyer the 01E requires way too much work for a standard front engine rear drive application. It works for the 944 because the 944 is a rear mounted transaxle. A T56 will not easily adapt to an 07K as uses a front mount starter that interferes with the block

[@geneqco]

I've had a couple of 07A's in the past so have a bit of a soft spot for these. What size and configuration of exhaust are you running post turbine... may be a way to help with the TQ drop off without changing turbo.

[@BoostBrothersGarage]

Running 3.5” from the turbo all the way back with a MagnaFlow muffler. Considered dropping the exhaust at the downpipe but doesn’t seem like 3.5” would be a problem

[@geneqco]

Yeah, no doubt turbine hot side would make a significant difference but would be interesting to see the difference made on the dyno by dropping the exhaust at the downpipe as you suggested. LR had significant gains on a fairly stock 951 S at 16 psi boost using a 4" exhaust even though it seemed to be mostly 3.5" with the final section at 4". I think the pressure wave builds along the length of the exhaust which is why there can be gains in a tapered or even stepped exhaust. Anyway, I've really been enjoying following this so thanks for all your posts and videos and the tremendous effort in making all this happen - keep up the good work!

[@BoostBrothersGarage]

Thanks! We with drop it to see what happens!

[@BigGroupHug]

Is this an endurance based engine tune? Or is it for making highway pulls and quarter mile passes?

We built and tuned it for road courses. We tuned in VVT and made the torque curve come in early and stay strong until red line. Or when the turbine wheel chokes things haha.

3:45 not gonna lie though, that is one fine N/A engine, too! If I ever need to chuck out the old Bosch KE-Jetronic in my 5-cylinder Audi, I'll come knocking on your door ;) BTW, how does the turbo 07K compare to the 944 Turbo inline-4 with regards to weight and COG when you include the respective ancillaries? 5:14 gotta say, when you remove all that plastic cover crap from modern engine bays, at least sometimes a gorgeous engine is revealed! 7:08 - dumb question probably, but why can't it be the cold side? I was thinking maybe some intercooler choke-spot.

[@BoostBrothersGarage]

The 07K is lighter and sits further back in the engine bay. It definitely improves the weight distribution! The cold side is possible but not very likely due to using 2.5” intercooler piping and a 3” core intercooler. I guess the throttle body could be a touch small but shouldn’t cause it to die off like that. Factory cams may be a part of the problem!

@@BoostBrothersGarage cams were my thought too, I seem to remember Hank saying the stock cams weren't much good past 6500 or 7k. Could be a combo problem. And damn near a 50hp difference between dynos... that's more than I thought it would be.

[@BoostBrothersGarage]

10% between dyno’s, I think that’s about right. The Mustang dyno is better for tuning because it can properly load the car down. The DynoJet is an inertia dyno. Cams weren’t an issue at lower boost, it made power to 7500. But, it could very well have become a restriction as airflow increased.

[@BoostBrothersGarage]

No issues so far!

[@ThatJaxsonGuy]

I am late to the game on this as I just saw it, but it is possible it isn't a turbo issue. The heads/ cams may be out of efficiency range and may not be able to flow enough/ properly to make power beyond a certain RPM. I've seen drop offs like that where larger turbo swaps still do the same. A lot of the modern 4 cylinder turbo cars do that. Like the Fiesta ST/ Focus ST. No matter what turbo and fueling, peak power remains essentially the same RPM with drop offs. Great set up though! That's a hell of a build!! I bet it's a blast to drive!

[@BoostBrothersGarage]

Pretty sure it’s just the factory cams
