Thread: Think I went with too big of a turbo...

It blows me away that this thread has side-stepped into a tuning argument. The tune is not the problem. The engine is in great shape. It's those cams with his setup that are the problem.

Wanna fix the problem? New manifold or new cams. Done.

Do me favor. Explain to me why cars with simillar set ups as Vadims are making more power?

Maybe it's the FL inflated numbers theory?

Do me a favor and prove it. Post a dyno sheet and setup specs and show they are making more power.

Don't forget pics of the manifold.

Similar but not exact man. For one we dont know how much power Vadims car is making because he hasntI dynod it. Maybe once he dynos it and makes a pull to 7800-8000 rpm where it will make power to and maybe he is making numbers close to others. Again he is only on 10-12psi on a 50 trim turbo. Its not gonna make insane numbers anyway, but that turbo is capable. 10-12psi is not even in its efficiency range yet. When he gets to 18-20psi if he ever chooses to do so with some race fuel in the tank, I think he will be more impressed. Thats where the turbo shines.

Basic chipped ecu's have made great power and when your in the 300-350whp range having a tune might net you a whole 15-20whp at most by optimizing everything. Unless the base tune is just running like absolute crap, rich as all hell to the point its sputtering and so on, a tune is not gonna gain you much at those levels.

Again, Vadim knows what he is doing, he is taking all the right steps and making all the right changes and following proper procautions to make sure nothing bad happens to the motor. I dont get what the big freakin deal is about he needs a tune. He is tuning it, just not on a dyno.

So again, lay off the why is one guy making more power than another with "similar" not same, setups. We dont know how much power he is making and until then this arguement is 100% pointless.

I would like to see how the car would perform just driving around the block with no boost. Just run a WAI and see if the car will go. When I was having issues with reversion, the car wouldn't run for crap NA. The exhaust was so choked up.

I thought it was a tune issue too. I thought JWT timing maps were garbage, and went through the same motions with timing as Vadim. Raising timing to bandaid the issue. But the car still ran like crap. But look where I've come... From 268whp on 16psi to 360whp on 16psi. Now, ~400 on 16psi.

Liars...... We are all liars. You have people who actually own the cars or have worked/tuned cars come in here and have stated their results yet a picture and a dyno sheet will make it all good?

You guys keep building your theory built cars while others make moves. Some of the best SR20 builders on this forum have shed light on the matter yet it is questioned just like everything else. This VE-T thing is nothing new. We built a VE-T car 6+ years ago that made more power than most on this forum have yet to make with more aggressive set ups.

Vadim I hope you get your car figured out bro.

My old setup

My impressions from 2007 quoted.



Here is my 3rd gear pull info from '07
Duty cycle at 7400rpm for injectors. 70.46.
Max air flow: 4.52V
Max speed: 97.5 (with oversized tires so this should be around 100 or so)
TPS voltage 4.02V WOT
MAX timing: 22*btdc most runs hit 21* only. (dizzy is set at 19)
MAX water temp: 199.4 on last run.
AFR: solid 10.7:1 at rev cut, between 12.5-11.5. Higher rpm=richer mix.






Here is after I went with the tubular

Who has stated their results besides GIO?

Who are you referring to? Me? Theory built?

You guys claim big power numbers, and yet rarely blow up a tranny! I went through 4 last season alone. 4 p11 transmissions. I even pioneered the cheap fix for it because it was costing so much to replace them. I literally cleaned out the entire state's junk yards of B15 and P11 transmissions. But I'm only making 450-480whp with 400-440lbft torque.

Whose car are you referring to that made so much more power than anyone else? No offense, but you FL boys sure have big egos.

Lol at this statement.

I beat the piss out of my car for 3 years on a road course and strip and went through 1 P11 with a car that makes more power and tq.

What does blowing tranny's have to do with anything?

I seriously had enough. You guys have fun. This is why so much info gets passed through text messages and FB instead of here.

If you guys were making power like you claim, you would break trannies. Unless your car is completely gutted, you cannot fight simple physics. But that's not the point. The point is that you guys come in here with this "almighty" attitude, and tell Vadim that his tune is wrong. Just like you guys told me that the VET cams would suck. Just like you guys told me that reversion is "theory".

To say that you know that his tune is the issue is juvenile, especially since you guys haven't (in most cases) done all the testing I have. It's all well documented, and I've posted the quotes.

Point is, you guys come in and say he is doing everything wrong. But you give no insight to him. I've asked before, and I'll ask again. If there is something wrong with his setup, what do you think it is, and what would you do to fix it?
