I had a chance to run my ISF on the quarter mile strip in Portland, Or. What a rush! The first pass in drive I ran 13.39 at 108 mph. Second pass easy on the throttle in manual mode no traction control 13.09 110 mph. Had to go one more pass nailed the throttle and cooked the tires in the first three gears and spun that hot rod. Thank God no damage. Except for the soiled shorts. LOL

FYI: If you are going to run the 1/4 mile, lower the Tire Pressure on the rear tires to about 18-20 PSI, just depends on the weather. Also, Get those things warmed up !!
You should be able to click a 12.8x and trap speed around 115-118mph....

After that I doubt I'll be on the track again. It was an awsome site. When I get the vidio I will post a copy.

That's what the car should be doing !!! Now, throw some Drag Radials on it and see those numbers dip even lower !!! ;)

A majority of IS-F I've seen run mid 12s with good tires and some lower pressure or with drag radials. Still 13.39 at that altitude is good for being your first runs. I agree with IS-F Champ, lower your tire pressure so you can hook better or get another set of rims with drags on em and see what you can do but always warm your tires. It's amazing the difference. Would like to see your passes, it is always fun watching others especially if they beat an IS-F hater or non believer lol.
