yeah I seen that once before, Very good article. Bill is the man!!

nice find. :tup

That is a good read. Thanks for the post. sticky this maybe

Wow, If I get some Weld Draglites and Front Skinnies I would drop aboy 60lbs of rotating weight! Thats over .5 seconds in the 1/4! Hmmmm....

i thought it was -100lbs= -.1 second :bang

wont work exactly like that...u will drop close to it but more because of using slicks the wheels themsself wont give u half a sec...one thing with Drag wheels u have less chance of breaking stuff and with skinnies u generally get netter reaction times cuz the car is more responsive off the line...but if u r running ;ets say 13.0 on a slickl right now using lets say V6 wheels u wont run 12.50s by switching to drag wheels...

the article is very good Bill was one of the first if not the first to run 12s with a completely bolt-on 2V 4.6

i followed his advices long time ago when Stangnet was the board to be

i ran 13.2 @ 105 with nothing more bus Drag Wheels, Slicks, 4.10s, Foxbody Springs, 90/10s, MAC Dumps and some minor weight reduction...thru stock paper filter and H-pipe

That is for sprung weight. Unsprung weight eg wheels, brakes is .1 for every 10lbs.

I managed to get mine to go 13.20 with just ET drag slicks, Eibach drag springs, an offroad X pipe and the almighty K&N. Stock gears! Hoping to dip into the 12's this year if I can track down some sticky tires again. :)
