Default 654whp/499wtq Clark Turner Tuning sleeved/forged 2.5l-PTE6466-GSC S3 on e85

Finally got my fuel pressure issues resolved and got some tuning done. The poor little Walbro 460 pump is just about at its safe max. IDC was ~85% and the fuel pressure started to taper off slightly so it was as far as they felt safe on the single pump. In the future, I will be doing a twin Walbro 460 setup.

I managed to get only 1 pull on video. Unfortunately the normal Android camera application was acting screwy and would only record for about a second. I managed to work around this by taking a video with Instagram. This is one of the early pulls and I don't know if it was on the full 27 psi of boost on this pull.

The most amazing this about this post is the fact that you were able to tune the car in 95* weather and not 115*+ weather!! Hahaha jk

Sick build and car man. I'm liking it. As soon as you can turn it up I bet it's going to be a monster!! Rev it out!! Glad to finally see some High-HP Clark Turner cars.

Looks very nice, congrats

Yeah the boost seems to be higher than 22psi according to the graph. Maybe even 27ish

Yeah this stupid fuel pressure regulator issue is very infuriating.

I myself was confused at this. Clark said it must be off because the logs show minor fluctuations between 21-22 psi

Clark keeps telling me it is actually 22 psi according to the logs. They use the corrected power on this dyno as it still reads lower than a dynojet. From what I've been told, the corrected power reads ~9% lower than a dynojet. Numbers are kind of irrelevant though when every dyno reads different haha.

I've tuned STI's that only go to 22psi of boost before in the logs as well. What does your boost gauge say?

The stock MAP sensor max out at 22.7psi.

My Defi boost gauge agrees with what Clark said his logs show. My boost gauge reads 22 psi.

I'll get one once I get the fuel pressure regulator replaced. I'm Cobb speed density and have not had a stock map sensor for probably 3 years (UTEC speed density before that). I'm pretty sure it is a 5 bar map sensor.

It doesn't matter to me if people hate. Once this thing is turned up all the way then I don't think people will have anything to hate on.

It seems the car doesn't really make power until 5500 rpm+ so why did you not choose to go with a 2.34L motor and rev it out to 8k+?

I mean, looking at the graph you have a useful power curve of 1500rpm, that seems pointless to me and not very "usable".

Impressive power numbers, but just doesn't have that much area under the curve. How does it drive?

A lot of that rightward shift of the powerband is from the GSC S3 282 cams. GSC doesn't rate them to be effective until 5k rpm. I thought about going with a longrod from MPS, but I decided to stick with the 2.5l. I think it drives great around town etc. I know it's a bad comparison, but I have a friend with an Evo IX MR on a built 2.0l with the 6266 and Kelford 280 cams and my car is much friendlier on the street.

I plan to eventually do the dry sump kit from ARE Dry Sump alongside the second Walbro 460 fuel pump. I should be able to take the car out a little further with those. I currently run it out to 8k rpm.

Yeah a dry sump should help. Rev it out I guess, but I'd talk to a builder first like Micah @ 3MI or Dom @ MPS, etc. before going much past 8k lol.

Once it spools, it's great, super aggressive cams though. Have you thought about Radium Surge tanks?

Oh and I love the look of your car, clean and neat with low-key accents, very well done.

what are you using the car for? It doesn't crack 200whp until 5500 rpms. I'm sure it's fun on a track but doesn't seem too streetable.

Your car sure looks good!!

Just saw this post. The car ran a peak of 25.5 psi fading down to around 22 to 23 at power peak. It uses an AEM 3.5 bar map sensor that is accurate and calibrated. I rolled the throttle out up top and detuned this car to 654 because he has one fuel pump and a stock location oil pump. IDC was 85% and Oil pressure needle was shaking back and forth at 8000.

This car has BIG tube headers, BIG tube intake manifold, BIG header ports and BIG cams and BIG 6466 which all hurt midrange and low end and help top end. So that is what the car has. Top end power and no midrange power. However, At 22 psi, I think that is a pretty good number.
