See my post under Dyno, but summary of first pass power after head, exhaust, supercharger, and tuning on 95 LT1 was 375HP and 410TQ. Then........made these mods:

-Electric water pump
-MSD 6A BTM
-MSD Coil
-smaller pulley to try to get to 6-7lbs of boost. I went from a 3.2 to a 2.7 lb pulley. This should add 4-5 lbs boost.
-went to smaller injectors to try to get better throttle response - from 42lbs to 32lbs.
-added a cooling fan to the intercooler

Had to send the supercharger back for a rebuild! (this is only months after a previous "rebuild" - ATI would not warrenty the orignal work -- the impeller came loose in the housing with less than 200 miles after first rebuild!!!

New Power Numbers:
357RWHP, 389RWTQ

That was a BUMMER.

I AM NOT running out of fuel at any point - I kept 11:9 Air/Fuel from 3000 - 6000 rpm. (about 12:1 with the 42lbs) Even so, I suspect the smaller injectors, although throttle response is GREAT now........

I am only making a little more boost?? I am only making ~5lbs now? The pulley I have on there should make at least 9lbs with my set up??? Any suggestions here appreciated.

At this point, pretty dissapointed. My next steps:

-Go back to the 42lb injectors
-Troubleshoot the system to understand the lack of boost
-Troubleshoot why I experience a severe drop in power about 4000 rpm after these mods. Looks like knock sensor, but weird it did not do it before. I am going to go back to the non MSD 6A set up and see if it goes away.

Any other suggestions are appreciated. Thx.
