blower only ET reductions, whipple, radix, ati.......
there is alot of FI going on around here now, anychance we can get a list of peoples ET reductions with a blower only change? it probably wont be a very consistant list since most people dont start with a blower on a stock vehicle and then there is the traction issue but we can try. all i hear anymore is RADIX, RADIX, RADIX, so lets see some numbers.
stock 99 ext cab 4wd... 16.7
add whipple at 6psi.... 15.3 (1.4sec reduction)
then add everything else, 6.0, headers, tuning, efans, posi, stall, 8psi with good gas... 12.77
whos next?

03 Silverado SS weighs about 5300 lbs without the driver.
15.3 stock
13.9 with Radix. Still some room for improvment by quicking the shifts.

1999 GMC SCSB Stepside with Gibson Shorty Headers/exhaust, Jet Intake/Chip ran:
15.6 @ 88 with a 2.4 60'
With Whipple, Gibson headers/exhaust, stock air box ran, stock tuning and shift points:
14.4 @ 95 with a 2.25 60' (1.2 second reduction, +7mph)
Probably could have gotten a low 14 second slip with some more practice.
Never ran it with the built trans and the Vig...but it should be capable of mid 13's.

Would not porting the compressor yield a higher flow rating?
Could you stick a Kenne Bell twin screw compressor on the Radix base like the blown Cobra guys do? I'd assume only the area where the TB bolts up to the back of the compressor would be changed from the Ford to the GM one.
