Another new 2010 Evo GSR came through the shop the other day.

2010 Evo GSR

Mods

Gruppe-M Intake
ETS 3.5" FMIC
ETS UICP/LICP
ETS 02 Eliminator downpipe
AMS HFC
Agency Power catback
GST Boost Pill @ 24.5 psi peak
GST custom dyno tuning using EcuFlash
91 octane

308 whp / 306 wtq

Dotted lines are stock tune with mods. Solid is with custom tuning and boost pill.

Great power for simple bolt on parts!



For reference on our dyno:

Stock 03/04 evo = 190-210whp

Stock 05 evo = 210-215whp

Stock 06 evo = 220-230whp

Stock 08 evo = 215-230whp

Stock 09 Ralliart = 190-199whp

Maybe I'm missing something, but this car with all of it's bolt-on parts isnt making much more power than the GSR in the thread below this one with just a magnaflow catback and AEM intake. Does this mean I just wasted a bunch of money bolting parts onto my car?

FMIC, LICP, UICP, Intake are all good supporting mods for more airflow which isn't fully realized until a larger turbo is in the mix.

HFC also limits the flow potential.

he pulls out the HFC, and probably pics up another 7-10whp and a bit more TQ.

Good gains! nice to see Gruppe M intake in the menu

That's a lot of area under the torque curve, great gains.

Thanks all, it does feel diffrent driving than before. And the Gruppe-M was ****.

Im glad GST is showing the numbers and what's was done here but my question is the guy tuned has full bolt ons... and he is 300+ ? what gives?

I don't see a large increase in peak power from lightly modded to full bolt ons with the stock turbo with 91 oct. The turbo just runs out of breath and the low octane prevents more ignition timing. With higher octane (like E85) there are nice increases but the turbo still runs out of breath at a point. Also keep in mind this Evo in this thread has a HFC. A test pipe would be a 10-15whp gain which would put it around 32X whp.

Once you bolt on a larger turbo is when all the bolt ons work well as supporting mods and the power increases a ton over the stock turbo.

I have been seeing 60+ whp gains from the stock turbo to Dom 2.0, BBK Full, etc.

The highest Evo 10 stock turbo on 91 oct on our dyno so far has been 320/320 with full bolt ons, but stock cams, most are around 310-315.

The highest Evo 9 stock turbo on our dyno on 91 oct has been 339 whp with full bolt ons, cams, porting, etc.

thanks GST for breaking it down for me....

Nice power for 91.

I think I got lucky on that one. I threw the AEM intake and MF catback on because I've been reading that some of the evo x piping is adequate enough for higher hp #s, thus do not need to be replaced until one is ready for a bigger turbo. As Bryan said, a bigger turbo is the important part on the 10 to really get the flow/hp going...or going E85 of course.

nice numbers and good information.
