MIL.SPEC 2.4L HTA Grn R2's E85 30psi = 632whp

So I finally got my car strapped to some rollers this morning.

A BIG Thanks to Alain & Dieter-Heinz @ HGMS Motorsports in San Diego.

The dyno used was a Dyno Dynamics, all other tuning for me has been performed on a dyno jet in 3rd gear. So all of my road tuning is performed in 3rd gear.

What I noticed was the difference in ramp rate, which isnt identical to 3rd gear acceleration / typical to a dyno jet or a flat road in 3rd, so the girl spooled differently & didnt really show what she produces on the street...but oh well.

The R2 cams drive great on the street & really get it done with this small-ish turbo! Boost fell off to ~28.x psi @ peak revs.

Here are the details

Mil.SPEC 2.4LR @ 10.5:1 CR
Mil.SPEC Lightened Crank
Mil.SPEC Porting Throughout
Mil.SPEC Ported HTA-Grn JB
Mil.SPEC 65mm
GSC R2 cams @ +1/+1
FIC 2150cc inj
DB dbl pumper
ETS FMIC
synapse bov


from 4k onwards, the power lines up to my calculated channel. Difference from road to dyno is boost ramp-up rate was delayed on the dyno in 3rd gear.

otherwise, on the road, via aem datalogger, im making:

~240wtq/dj @ 2500 rpm
&
~400wtq/dj @ 3000 rpm
&
~520wtq/dj @ 3500 rpm

A Bone stock 2014 GTR averages ~382 whp / DD #'s @ HGMS.

Thanks.

I honestly believe I can make more top end power out of the green! Stay tuned!

Looking to find out in a few weeks

I will definitely turn the boost down a bit. She hits hard.
