How much boost will this combo make? Horsepower?
Planning on running a p600b w/ fmic with a 15# pulley and maybe a 23% underdrive pulley. Planning on running a much bigger k&n filter as well.
How much boost can I expect from this setup and horsepower/torque? anyone with a similar setup to compare dyno numbers or people that ran/run the 15# pulley how much boost shows on the guage-mods? My car has the black bowtie in the bumper cut out so the fmic is visable. How much boost will the 23% underdrive pulley add? the filter? Engine will consist of: (93 octane with toulene added CAM tuning later) 50# injectors dual intank walbro 255s studded 2 bolt main forged crank forged rods forged dished pistons arp bolts stock heads stock cam 1.6 roller rockers long tubes (might run mac mids for a while though) 4l60e with a s10 converter and oil cooler stock 10 bolt:mad: |

An underdrive pulley on a car like a LT1 Corvette will actually make LESS boost, as it would slow the blower down. I would imagine that you should expect about 500-525 to the wheels, but that's just a guess. |
I've never seen a P600 make anything more than 11#'s of boost, so guessing that you make that, my estimate on your RWHP will be around 465 or so with your setup.
If you would change up the heads and cam, I would guess maybe another 75+ extra RWHP though. |

I heard one guy mad 12# but I think he said boost decreased when he did heads and exhaust so I don't know if he was making 14-15# before that. Anyone else care to comment on the 15# pulley? |

Mods in sig, stock ATI inlet collapsing, the car saw 10.5# boost, 498RWHP. This was wit the 2.55" pulley(15#'s)

A quick way to estimate max boost. Courtesy of yours truly.
http://www.kennedysdynotune.com/Blower%20CFM.htm You can use the formula with a compressor map to estimate boost at less than max impeller rpm. |
