990awhp and 581 awtq at 41psi

Then you up the boost to 54PSI and only 10 more whp? Is there something wrong?
We noticed on our 42r that 48psi to 54psi didn't give us much gain. Timing sure did

Exhaust housing is choked up and out of efficiency/flow by this point..

Car will be back on the dyno shortly, with some boost control changes, larger exhaust housing, and some giggle juice.

Thanks for everyones compliments on the video.

Larger Housing means more LAG right?

Not in certain cases...probably not in this case.

Especially not with the nitrous.

wow. Simply amazing what can be done with this engine. To think my meager 330whp is enough for me.

I still find it amazing that no power was gained after 41PSI on a 42R. That Truely amazes me to no end.

Stop thinking as "41psi" as a number, and more like airflow. 41psi on one motor certainly doesn't mean it'll do the same horsepower at 41psi on another motor. This motor makes the same if not more horsepower at 41psi as other 4g63's do at 50+psi. There's a good reason for this.

Super efficient headwork/cams/manifolds/intercooler setup make more power at less psi.

Yeah well this is a 42R, so it flows quite a lot and above 41PSI. That is an amazing WHP number for 41PSI BTW, VERY nice.

As stupid as it sounds, how many 1000+whp 4G63 Evos do we have guys? and how many DSM 4G63 also?

Speaking of the car, that is sick by the way, congrats!
