Rail pressure between the NA and the TII pumps are the same.
Putting in a TII pump (unlike some other aftermarket ones with higher psi) won't make your car run any richer.

The porting does change things though... the way the stock AFM's are, and the way the ECU interperets the signal, is such that when they are flowing more air, the ecu overcompensates with too much fuel, because it's outside where it was designed and programmed to run effeciantly.
The more flow, the higher the overcompensation.

60' of 2.488 sucks that explains the 1/4 mile time...

After talking a bit with Rob, me putting down around 170rwhp is good. He also said with more miles the motor will make more and more power. But not to much more. He says that i should'nt expect more than about 200flywheel hp from a engine with a stock idle, and pass emmisions.

We also talked about exaust. He seems to think that the 2- 2" mandral bent exaust is the way to go. He's told me in the past that peripheral engines don't like a long collected exaust. If you have to run a long system on a p.p. motor, best results where with duel exaust. The same (not nearly as noticable though) goes for my 90 n/a engine, that it would make more in the mid to upper rpm range with the duel vs collected, as the scavaging effect is very important.

So in conclusion, i'm going to stick with my duel 2" exaust, be happy with what power i have....and weight for the motor to pop....then add a little more port to it.

I'm still going to post the dyno results...but i have to borrow my brouther in laws camera to do it. SO please be patient.
