how can i get a few extra hp? test pipes, plenum spacer, pulleys?. any1 have an idea?

thanks rory

 

You will surely get more HP if you add Test Pipes and Plenum Spacer...but I would stay away from lightweight Pulleys now that you are FI

 

I think plenum spacer is worthless, you will gain around 20-30HP by test pipes alone, and you will lean out a bit and will gain like 1-1.5 PSI

 

+1
And if you do a pulley, I would suggest a harmonic dampner like the ATI or Fluidyne.

 

Are you by any chance AT?

When my tune was done it got me about those numbers before test pipes - after test pipes it put me up by about 25tq and 30hp.

Highly recommend test pipes!

With a super conservative tune and and the same boost.

Just a thought

 

fact: turbos dont like back pressure

 

thanks very much. so ill get test pipes. what about the aps tall boy or cosworth? i just neet a a little more power.

 

whats your A/F right now?
