Well he is only running 21 psi. and on 91 oct

 

With a 2.3L stroker you should consider a bigger turbo.

 

That turbo is disappointing on pump gas. Your numbers are fine. The stock airbox makes no difference at that power level, questionable if it makes a difference at any power level.

STD's are bad news.......

 

bigger turbo or higher octane gas is your answer.

though this number is definitely very disappointing even taking into consideration the crazy hot weather.

maybe try another tuner?

 

Get a different turbo and put some alky in her. Get the most out of your stroker. good luck

 

Like you did

 

I had the pleasure of tuning John's EVO yesterday and it performed well.

If you compare his powerband and numbers to other similarly modded EVO's that tune on my dyno you will see that his is right in line. The 2.3 spooled that FPG turbo extremely fast providing some great torque output.

Everyone knows that this turbo doesn't really wake up until the 25lb marker. A ideal setup would be a Methanol injection system allowing the OP to really enjoy the FPG's true power capabilities.

Its easy to get caught up in numbers, but I do my best to encourage people to use the dyno as a tuning tool. Many of the EVO's I tune are daily driven street cars. They must be able to endure street conditions like high heat etc.......and at the same time do racing on the weekends. Many have no desire to put the car on "kill", they love their investment too much.

And John, just in case any of these knuckleheads got you worried about your injector scaling, it was done by scaling the injector value up and modifying your Injector latency values to match your Denso injectors.

Your car was a blast to drive on the post-tune test drive. Now you can enjoy the fruit of all your hard work, time and sacrifices.

First, let me state, I mean no disrespect to you at all.

I think this statement is becoming way over-blown on this forum. There have been multiple threads showing that the pressure drop (ex. The thread that tested the buschur filter alone vs the stock box, for example) is reduced as well as tq/hp gains.

If you get gains with an intake even on a stock(ish) evo, why is the stock box fine??? To me, that's a restriction. Sure, the gains aren't much on a stockish evo, but with more and more mods, the aftermarket intake should help and complement them even more.

I'm not picking on you specifically by any means. It just seems like stating the stock box is good up to XXX hp is deceiving and misleading...

Carry on...

 

my personal data suggest there is power to be had by moidfying your intake, either with air box &/or maf:

a effective heat shield will help prevent exh/radiator heat being inhaled by the open airfilter:

the above 2 temps show the merit having the aftermarket airfilter enclosed with air being fed to the filter via a tube/scoop.

regardless, i think there should have been more power.

i strongly believe a fp-grn should be able to run 23/24 psi safely on 91 octane.

i run 23/24 psi with my tme. yeah, i can get a high boost spike, but the power gain for visiting that boost/knock threshold becomes very thin. that is why many people like 21 psi, there is a wide margin of safety.

you will never fine mbt on 91 octane. i know on my car that 24 psi @ 5k will generate more tuned power than 21 psi with tuned power, all on 91 octane.

the fp-grn should allow for more timing anyway, because there should be less pr (backpressure) due to the larger turbine wheel.

what cams are you runnig again & where are they set at?

 

You numbers are absolutely fine. 21psi is very conservative and is 100% the reason you didn't make the 370whp/wtq that others were expecting. With this turbo, you could easily see 30whp more with just two more psi of boost. You have an absolutely floggable car. Enjoy it.

Remember, there is a huge difference between 91 (this tune) and the 93 octane others use around the country.

I have to say this is one of the most informative threads i have seen on this forum. I would have agree on the fact of why put a 2.3 on a green and not run meth. Not bashing just informing.... i love meth!!!! I had mark at turbo trix tune my evo 8.. i have normal mods intake/tbe/mbc/buschar fmic/buschar upper and lower piping/stock 8 turbo/ comp 280 cams/ and meth!! Now on pump 93 it made 350 whp and 351 tq at 22 pounds. Meth woke it the duck up!!! Very next run with no cool down time on meth it made 422 whp and 433tq!!! Thats a 72 whp and 82 tq increase!!! O yea it was at 27 pounds on meth. This is also my daily driver so i know how you feel about that but meth works!! Now before any says those numbers seem really high i would have to agree! But my point is not the hp #'s on meth but the increase that it made. Best 450 dollars i have ever spemt on my car!! Just my 2 cents.

O yea not sure what the dyno was? sorry

 

Dynojet 424X. One of the best features of Dynojets is that they draw highly precise dyno plots showing even the slightest hiccups and imperfections, while other dynos draw super smooth crayon-like lines with very little resolution. All brands of dynos have their pluses and minuses.
