Heath's 536whp Pumpgas Evo X
 

Heath bought his 2012 to replace an almost 700whp Evo 8 and had alot of the same goals. As we all know some of the 2012s started off with a little less power than we hoped per mod and Heath's was one of those.

After all his bolt ons on the stock turbo he managed to get 342/321 on a 28psi spike.

So it was back to the drawing board for Heath and he settled on an ETS 6262 kit and the needed parts to make this work on the stock motor. From that we got the car to make 487/340 (492/350 uncorrected) at 27.8psi

It didnt take long to learn that the 2012 ROM does some funky things at high airflow and power levels. It was not consistent in AFR per gear, or per pull as far as that goes, and would randomly drop 5-7* of timing. This lead to a damaged sparkplug which brought the car back to us to investigate. After some fooling around I found that benchflashing a 2010 ROM to the car cured all the inconsistency issues I had seen (see Power Variance thread) and we were back to game on.

In the meantime, Heath decided that a built motor and valvesprings were a good invetment so we tore down his 3700 mile old motor and did one of our standard 2.0L stock sleeve/stock bore builds-

ER Spec'd 2.0L 4B11T
JE FSR drop in 86mm pistons
Manley I beam rods
ACL bearings
GSC valvesprings
FIC 900
ER Spec double pumper
Stock cams, Intake, head porting
ETS 6262 T3 kit (0.82 A/r)
ETS 4" intake pipe kit with 3.5" MAF
ETS 3" FMIC kit with piping
ETS Quiet exhaust

Today I went back to the dyno and started making some pulls and tested the water of this now 9k rpm capable motor. The first pull was 458whp @ 23psi so I was encouraged by what I saw and started turning the boost up till I got to this-

Here is the start to finish to compare all phases of Heath's build so far. The next step will be more RPM, more boost on racegas, and we'll see where it goes from there.

Green is stock turbo @28psi
Red is 6262/stock motor @27.8psi
Blue is 6262 built motor @ 28.5psi

Nice #'s

is that usual for the torque to be around 369 at the 536 hp level for a 2.0 ? i remember my 2.3 making 386 torque at only 381 whp curious what could all affect that and how important torque really is , can u really feel the difference with a car with same peak hp but has more torque

Its all turbo dependent really, the later it spools the less torque it makes for the horsepower.

HP = TQ * RPM / 5252

So your car making 381/386 was probably a smaller turbo (stock or Green) on a 2.3 so it made the 386 low and was down to probably 300 ft lbs at peak power (6500?) This spools later, makes peak torque at nearly 7k even though its lit off at 5500.

So when you take 369 ft lbs at 7k and pump it back into that formula-

369 * 7000 = 2583000 / 5252 = 491whp

My 3586 equipped IX made 575/400 on the 2.0L at 29psi where on the 2.4 it did 648/478at 29psi and the torque happened almost a 1000 rpm sooner. On a 2.0L with the stock turbo it made 435/400 at 32psi and was making that peak torque 1500rpm sooner than even the 2.4 did on the big turbo.

Aladeen motha trucka!!

Nice looking setup, 6262 looks like a solid setup.

Race gas time though! I wanna see 700whp :)

Wow, awesome setup.

Stock cams still but with GSC Beehive's? What! Awesome!

Really nice numbers. "I like where this is going" *Quagmire voice*

Looks like a fun street car to me! :)

Very very nicely done!

Yeah, long story on that one. Still stock 2012 camshafts and stock head but I think if there is budget in the future the head needs ported. I would like to see a ported head with 1mm over or larger valves and some aggressive camshafts.

Nice job behind the keyboard-- Power curve is perfecto!!

That turbo kit is badass!!! :D

Thanks my friend :) {thumbup}
