Well, I got the car dynoed again today with the addition of a 2.70" pulley, a 10% OD crank pulley and a 45-degree angle from bypass valve to powerpipe because I was getting some backwash issues with my draw-thru MAF causing some slight driveability problems.
Well, driveability is very good now.
Now, the before:
525rwhp @ 6400rpm
454rwtq @ 5000rpm
And the after:
548rwhp @ 5600rpm
516rwtq @ 5000rpm
Now this was with 16.2 lbs. of boost, 18 degrees timing, 93 octane.
I am real happy with the torque. Pulls like crazy now.
The problem is I was having spark blowout above 5600rpm, so the HP and TQ nosedived above that RPM.
I think that pulley combo is capable of 19lbs at 6500rpm. I hope to get 580rwhp if I can get the spark issue resolved.
Ignition System: TR-6 plugs gapped at .032, MSD coil packs, FMS plug wires. I had an MSD DIS-4, but that took a crap on me a long time ago, and was causing a miss. I bypassed it and everything has been fine up till now.
