I think Ive heard of high 9's, but probably more realistically, low 10's. You should also bellmouth the dutt neck inlet instead of leaving it in the as cast shape, where the entry walls are sharp edges. You can gain another 1psi on top of the gains already there by switching to a dutt neck, by simply bellmouthing the inlet and sawing off the rolled lips on the inlet and outlet of the steel up-pipe. Those lips are terrible for flow. It throws the stream into a serious tumble and heats the air up. I gained 2.5psi from the dutt neck, 1 psi from those mods I mentioned, and another 1psi from a 3.5" buickGN.com intake tube.

Ran that in TSS at the 06 Nats. Used a TA66 turbo, ported iron heads, 224 hydraulic roller,.040 JE pistons. Put the big neck stock intercooler on after noticing my stretch intercooler was busted. I was suprised that it didn't hurt my performance. That was at 26 or 27 lbs and zero knock. I'm sure there was more left but I didn't push it.

Thanks for the info...You helped make my decision to go with the Dutt neck Instead of spending the extra money (Possibly needlessly) on another intercooler. I am only looking for low 11's...I had a buddy that saw absolutely no gain with his car going to a V4 from a Dutt neck...That was on a mid 11sec car. My combo, cpt-66BB Gn-1 aluminums 208-201 FT cam 75's...TT chip...Dual Nozzle Alky...Yadda...Yadda...Yadda. Thanks,Shawn
