AP2 Comptech kit w/aftercooler on my AP1 no engine management besides what came with it.
Boost gauge read 6 psi at 8800rpms.
AFR's were 11.5-1 until vtec and then it jumped to 12.5-1 to 13-1 in vtec.

HP was 305.81
TQ was 188.08

Dyno sheet scans to follow.

how much fuel pressure are you running?

 

Whatever it comes with from comptech. We did not have fuel pressure

 

congrats man. you might wanna richen it up a bit though. i say try to keep it at 11.9-12.1 after VTEC

 

I got 304 / 190 with my AP2 pulley non aftercooled comptech on my AP1. I was seeing 8LBS of boost at 8800 RPM so you might have a loose belt. I would say that you should be seeing 7 lbs of boost at least.
Also my AFR's were at a max of 12.9 somewhere in vtec and then droped to around 12.5 at redline. Your tune should be good as it will run wayyyyyyy to rich down low if you try to richen it up more.

 

The aftercooler will rob one PSI.

 

correct

 

The belt is definitely not loose.
Aftercooler robs a little but makes things cooler and is a little insurance.


We richened it up on the dyno and the low end AFRs were near 10s and high end was 12.5.
I should be fine with how things were done. I have not heard any knocking or pinging while driving or on the dyno.

 

Am I reading this correctly? Those numbers seem to be backwards to me.
