...if this is the case, i ordered the 3.25" pulley thinking it would be 10psi ..was i wrong?

 

a 3.25 in pulley should yeild 10 psi at 8800 rpms.

 

oh ok.. :heeeeew!!::

i thought i was going to be boosting a lot more than i was hoping..lol

thanks

 

I just ordered my 4" pulley from ASP and should be here next week. I'm almost positive that I should be in the area of 7lbs. Better not be 9lbs I trust these guys in the thread below know what they are running in their setup, some of you might wanna refresh your memory or refer to this thread below.

I did the same thing last week! the 4'' produces 7 psi

 

hmmm. I never seem to read about AP2's pushing more boost and what pulley sizes to use. I imagine the 4" pulley is what I have producing 5.5-6 @ 8000rpm. So I guess 3.75" would be the next logical step up.

If my teachers would have used pulley sizes, boost and belt length as real-world reasons to learn geometry, I might have paid more attention!

On the injectors - not to jack the thread but there must be some downside to oversized injectors. Price differences are very minor. Do oversized injectors comprise idle quality or low speed driveability?

 

without being able to tune the bigger injectors it will run poorly and then stall out, cause of too much fuel. if you can tune them they drive pretty good
