running catless smells so bad though. and the ozone. think of the ozone.

 

Ralph at excessive used a vacuum pump on the little hose that goes to the pressure regulator. CJ

 

BTW, those are some nice numbers Von! CJ

 

I have to look up my dyno charts. The last time I dynoed my `91 NA I was in the 151-156 range. That was with Racing Beat headers, Presilencer, 50MM cat back, Apex Power flow intake and a Racing Beat Aluminum Flywheel. I have changeed to an Apex single N1 and back to my stock flywheel (per my racing rules) and gone to an electric fan. I need to dyno again. I have been told that in race trim with no porting I should be able to muster 170 at the wheels. I am sceptical but I am going to do my best to get there (to be somewhat competitive on the track).

Wow that would rock to have 170rwp...Doesent sound feasable thou without some interesting DIY custom mods or a stand alone...

Well thnx for the help PPnos when before I went to the dyno. I know your making 170rwp mabey 175rwp you say with a mild street port and same mods as me. So those numbers on a stock port do seem a little high. I will be going to the dyno again soon so I will keep you posted. I will break 160 but dont know by how much.
