I just had my Comptech SC(A/C) and 7lbs pulley installed. With a T1R test pipe, HKS HP exhaust, and a conservative AFR(oh, and 70K on the OD ), I pulled 323.7HP, and 191.7trq. The strange thing is I'm only seeing a little over 6lbs of boost at around 9K. Anyway, what do you folks think?

seems about right....at 7.5 lbs of boost with similar mods i was making about 20-25 hp more and about 25 more tq on a dynapack as well. I wonder where you are loosing the boost. Was it measure at the manifold I take it? Also your running a conservative A/F where as my car was running a bit lean probably making me some extra HP
are you running aftermarket gears?

at approximately 8900-9000 you should be at about 118 mph

 

I am reading boost off of the manifold, to an Autometer Nexus gauge. The car still was the stock 4.10's. I do have a "Godzilla" BOV on the car. This would be the only place I can see me loosing boost?

 

what did you tune your comptech s/c with ? Can you post your A/F graph also ?

 

Not too bad.

 

Birdie,
It was just tunned with the FMU Comptech supplies. Thats one of the reasons it runs rich... For the time being I'm just going to enjoy it as is(untill my header comes in ). I'm sure if I was to put a computer on it (eManage, AEM, v-afc...), I could get more out of it, but I'll save that for when the "fun" wears off.

 

Kool.

 

Have you checked your belt tightness? It is the first place to look when loosing a little boost at the top with a belt driven supercharger.

 

Nice #'s , have fun with it!

 

Thanks sideways. I will take a look at it. How much deflection(?) should I be checking for?
