There is also the intercooler option, I think I forgot to get those measurments for you, if you still need them I will take them this weekend.



Gary, Doesn’t the maker of your setup claim 290 HP? How is it and the motor holding up?

I dont remember what the claims are but I do know my at the wheel numbers are within a few percentage points of his at the wheel numbers.

My motor is holding up very well, I am checking the oil more frequently and still changing the oil every 10k miles. The water temp is at oem levels. I still drive the car the same. I run it up the rev range daily. I never rev past 4k until the water temp is at 180ish

My car is dynoing at 230ish at the wheels I have a dyno chart posted on the board somewhere. I can repost it later tonight. I am basing my crank on rough math.


I have looked into water/meth injection but I do not have any experince with it so I decided to leave it to those that know what they are doing.


its exciting to see someone squeeze more horsepower from these engines. keep us posted.
