22psi on a 6262 should make over 500.

Friend made 470 on a t3/t4 .57trim on 91 at 18psi dropping to 15.(turbo was maxed out.)

I find it hilarious when people Make posts so matter of fact about a situation lol. There's many variables people It's not a cut and dry situation. Smh

I talked to the tuner today, says to look into a set of itr cams and a set of gears and come back for a re-tune. Not sure if it makes a difference or not cause im ignant, but i didnt have proper crNk case ventilation at the time either. Dont know if that would hild me back or not...

I would get id1000s before cams.

Maybe find a new tuner lol.

If dynograph is correct... 90mph means a 3rd gear pull which isnt sufficient for accurate measurement with a turbo that size. Final numbers and tuning should be done in 4th gear

I'd get the other graph interpolation (boost/rpm, power/torque/rpm, etc) than this. Your "tuner" is throwing imprecise suggestions without any rhyme or reason. The best 1:1 ratio is in 4th gear. It may be time for another tuner and to try this again.

Changing crankcase ventilation, ITR camshafts, all focus in the wrong direction. Even the injectors you have are capable of more power than that, (if not running corn-water).

I'd move forward and find another individual instead of running through with these suggestions... Sorry to say.

If the "tuner" thought this was acceptable and sent you away like your car was done, then tells you to buy more parts to throw at the issue, then he isnt a "tuner".

Any competent REAL tuner would have known something was wrong with the numbers when your car was on the dyno and should have been able to at least give you an idea of what the issue could be. I get you arent paying for diagnosis, you were just there for a "tune" but if he doesnt care enough to tell you something is wrong and where to look, go somewhere else... You're lucky he didnt blow your motor like a lot of so-called "tuners" have done to other peoples cars.

CLIFFS: "Tuners"....

my holset hx35 made 481 on 21lbs of boost lol. im going to have to agree with the others. find a legitimate tuner and not someones whos just pushing buttons on a laptop and giving you poor advice

efHondefender

isn't real street performance out of FL a pretty credible place, though? I can't imagine that they have shitty tuners. Their stock motor s2000 went 9's after all

roll8221

Yeah, i travel a couple hours to get it tuned there. I did some homework before bringing it. Realstreet and jay in particular hold records for the s2000 and the ariel atom??? They also have alot of super fast supras... jay def knows what hes doing..i think its more builders error (me) than anything.... as for the exhaust, i have a log manifold, 3" dp and 3" pipe all the way back to the hks hi-power, no cat...

Stock gsr cams will make 800+ hp. Time for a new tuner. If they're just telling you to throw parts at the car and not diagnosing while you were there and couldn't figure it out they don't belong tuning the car

v8killaz

well the least he could have did was let you know whats holding you back or his theory why the power is so low

blackeg

im sure that log manifold isnt helpin **** with a turbo that size. also check for collapsed flex piping in the exhaust and that your dumptube gasses arent being aucked back into the intake.

is your wastegate vacuum sourced from the manifold irvthe compressor housing?

Casey

iTrader: (5)

what log manifold?

get another manifold. I bet you pick up 75whp on a ramhorn or top mount, and i bet it takes less boost to do it.

SovXietday

Your problem.

You have a 700hp capable turbo being blown through 4 straws that are tied in a knot at the end. You can turn up the boost all day and you'll never squeeze any more power out of it.

With a proper manifold I bet your car will do 350whp at 8-10psi, and then take off when the turbo starts to push through the meaty portion of its compressor curve.

Turbo-LS

iTrader: (4)

Depending on what log manifold it is you can max that turbo out if it's say inline pro or spa top mount. The lesser logs probably not. It'll take higher pressure ratio due to back pressures as well vs a ramhorn top mount etc

Guys, just because a shop has built their own cars to run good times, doesnt mean they take care of people. There have been tons of shops/tuners that do wonders on their own stuff but couldnt give two ***** about their customers. And usually its because of what you see here in the last few posts... "But they ran X.XX so they must be good" and so on. They think their good rep means they can treat people anyway they want and they will always have business because hey, I ran 9's right?

Sorry but I would much rather go to somebody who is willing to spend a little bit of his precious time with me to help me fix my ride that I am paying him to make fast, than someone who everyone thinks is good, "cuz he ran 9's bro, hurdur" There are plenty of competent people in your area who are humble enough to not bank on their shop cars rep and actually help instead of sell you more crap you dont need.

Let's say you took his advice and went with cams, your major bottleneck is very likely that manifold, so once again you would not have seen the power you should. Making the car try to breath more through an already choked setup IS NOT THE ANSWER. This should have set alarm bells off right away. Sometimes if you call people like this on their ****, make them realize you know at least a little bit of what you're talking about, they might shape up and do you right. But thats less likely than them just spitting more garbage in your ear about how you need to give them more money to make things right. Sometimes throwing money at the issue (especially in the wrong places) is not the answer...

this man knows his ish and has proven it time and time again. People these days are so quick to put down log manifolds without any real experience. People have been using log manifolds for YEARS, and some manifolds even worse than a simple log (i.e. modified factory manifolds) and have made plenty of power. The simple fact is the car has an issue somewhere. It should make more power with what it has on it now. Find the issue, fix it... then upgrade
