CONTEST : Guess the HP and WIN!

If the car had a 4 speed I would guess higher. I'm wagering on the converter vs chassis dyno thing pulling the number down beyon the 18-20%. More like 25%. I figure 600fwhp x .75 = 450. You should have good air on Friday. Do you have street tires for the dyno?
Unfortunately I have slicks for the track and drag radials for the street which are brand new. I know I shouldn’t but I’m good with making a few pulls on the dyno with drag radials. Probably the only time they will get used since I don’t plan on street driving the car…. lol
