Just got off the dyno with one of our customer's 2011 GSR after its latest round of mods. Before it had made 337 on the stock turbo and mild mods but Will wasnt satisfied so some more tweaking was in order.

We added-

FP Black
GSC S2X camshaft set and springs
FIC 900cc injectors
ETS 3.5" Intercooler and piping
ETS Intake
AEM Tru-boost
AEM Wideband
AMS "Big" cast O2 housing/downpipe
AMS exhaust
ER double pumper (inline pump) kit

A few pulls on the dyno after a little time in the parking lot and a drive around the block resulted in this-



451.8/360 ft lbs at 27.9psi on 92 octane

Congrats Will, hopefully you enjoy

Thanks

Nice looking torque curve there! Congrats to the owner and nice job ER.

 

Thank you Aaron and English team!

 

Awesome job!!!Aaron is a great tuner!!

 

Wow nice job!

 

very nice curve, congrats! We all know Aaron know his stuff! Well done sir

 

sick with it son.

i am planing for 450awhp out of my red. wish me luck. lol

 

thanks guys.

We have done 427 at 28psi with the Red and a less restrictive exhaust (turboXS I think) and 460 with a ported head on the same car.

450 can be done

 

Nice, nice, nice. I love the great hp figure while the torque is kept quite realistic for a stock block. I hope to do something similar next spring. Great job there!

 

hows the mpg?

 

weren't you hoping for 500? what's holding you back?

 

Desire to not window the block i am sure.

 

O2 dump isnt there and exhaust is restrictive. What we have found is on 92 octane the Red and the Black are fairly close on power. For comparison though, the car I mentioned with the Red that made 427 did jump to 460 after the ported head. This is at 451 as is, so a few more mods should get it close. As far as I know though all the 500whp FP Black X have been over 30psi or on higher than 93 octane to do it.

Ah ok that makes Sense. Didn't know that exhaust was restrictive

 

Great work!
