G McCall, when the Formula with the Buick motor ran 10.20 @130mph this was with a 1.43 60' and the 20lbs of boost is very possible when you consider the combo is a PT70 4 bolt turbo, fully ported iron heads with port matched intake, a PTE FMIC, Accel DFI with 75lb injectors, and last but not least a custom grind cam, which I'm sure is a 220+ high duration cam and also the car has 9.5:1 compression ratio motor!!!
If you check out the Buick Products section on the PTE website
www.precisionte.com Joe Harrington(spelling?) is running a very similar combo with a PT72 turbo, fully ported iron heads and intake, PTE 220 roller cam, PTE FMIC, DFI with big injectors (75lb or 83's), and this car also has 9.5:1 compression ratio and has run 10.60's @126mph with only 18lbs of boost in a full weight GN!
Brad, is George Baxter's convertible SS really making that much horsepower with the LT1? Last time I heard the car was making 750hp with an Aftercooled Y-trim Vortech and was running deep in the 10's (maybe high 9's). I'm not sure, but I think 1000hp is pushing it on an LT1 and I'd think if he was running low 9's with 1000hp it would be with an aftermarket Chevy block like a Motown or Bowtie (4 bolt main block).
