You probably will only see 5psi at 5500 rpm. You have a lot of area/volume to fill. Time will tell.

now speedytang my setup is suposed to yield about 290-300 at the wheels na. With 5psi that isnt going to do much for me correct? what about should i see hp wise with 5 psi do i need a different pulley setup for this to make more?.
ps. I have it up for sale because of what you said and thinking of a turbo not 100% yet but if it sold i would go that route because i think 5 psi will not do it for me.

You need a VR4 to get some real power with those heads and being a automatic is another huge negative unless you have 4.10 gears. You will over spin the unit to get what you want unless you upgrade.

Sorry about the Auto I am getting my 500 posts and 2000 emails a day mixed up. Since red line is a true 5500rpm for your build before HP drops off you could try a 3.5" since your crank pulley is so small but throwing another $50+ on a pulley does not make sense at this point.

very true about the pulley. Right now im hunting for a turbo kit hopfully my SC setup sells and that will help me out a bit.
