Sup fellas,
I have been working with the guys at Evo to try and pick up some extra hp for my car. As many of you GT3 owners know, these cars are very under rated from the factory and most are dynoing at about 400hp crank (350 to the wheels) and above bone stock (instead of the 381hp crank the factory claims). Sadly I do not have a stock dyno for my car but, it was quicker that 2 other GT3's I have played around with in the past.
This was done at Evo's facility in AZ on their new Mustang dyno.
The car did 372hp to the wheels and 275tq.
They installed Milltek headers, highflow cats and mufflers. (Green lines on the dyno chart). They did the GIAC flash (red lines on the dyno chart) and are currently working on an intake/airbox (stay tuned) that is suppoed to pick up an extra couple of hp. I want to thank Todd, Mike and John for putting this great package together for me. The car is definately more responsive and feels quicker on the road. I will keep you guys updated once the airbox that they are currently developing is ready and will post up the additional dyno graphs.
Anyways, here is the graph and some pics of the car on the dyno.

BTW, corrected the car is now doing approximately 428hp to the crank.

Shame you didn't get pre and post numbers, they would be more meaningful than a single dissociated set of numbers. Here you know approximately where you are but don't know where you came from. A single set of numbers add a lot of dyno into the results which is almost impossible to remove reliably. Really need the base line to accurately compare.

Mr Michael B

Great numbers. Thank you for your efforts.

If the previous numbers were 350 WHP = 400 crank HP unmodified.
Then 372 WHP = 425 crank HP. COOL!!!
Milltek full exhaust and GIAC flash = believable.
The claims that bother me are the 380 HP to 420+HP with exhaust and flash.
Goes to demonstrate Porsche didn'g leave much on the table either.
Whats the cost?

LuisGT3

The correction factor that Evo gave me was 15% hence the higher #'s. The car was obviously higher than the factory claimed 380 hp and picked up around 30 crank hp with the flash and full exhaust. I really wish I would have had a basline stock, but their dyno was being put in when I brought the car in. It is a Mustang dyno (the Mustangs read lower than the dynojets).
This is the exhaust system on the car:

And a link to the Milltek website with more info on the system.

The whole package was close to $7k installed. The exhaust stuff was pretty expensive.

Luis I am in Mammoth right now (first trip in the new X5) and I will have to wait till I get home.
I might have posted them already I will do a search.
(its been friggen unbeleivably hot there unseasonably early had to get to the mountains. Has it been hot and humid there??)

LuisGT3

It was pretty hot during the week (not humid) it looks like it might be a perfect weekend. Low 80's and lows of mid 60's. I am really liking Scottsdale right now. (I won't in a couple of monts )

OldGuy

Yea I think I am dead when July Aug rolls around. I think I am going to be up here alot(mammoth)
I think I posted those charts and I cant find them Maybe if you are smarter than me on the search
function you can find them. I dont know how to do a 'AND' search Like Manthey AND dyno
if you can find them repost them.

DavidNR

Thanks for posting Luis. Very interesting. Milltek is pretty good stuff, had a couple S4's with their systems.

From what I have found/read the headers add torque and the cat's, mufflers and flash and slight HP.
370 at the wheels corrected is a good number.
Was 372 corrected rwhp?

Some programers have a portable flasher where you can flash it back to stock, Valet, 93, 104, 114 octane.
