Tires will do you right. And its so much more fun hooking and going then featheribg

Had a good time & nothing broke 😀 , Car ran good & for the most part it hooked decent feathering it, I got no tire spin on 2 runs, the other 2 it spun & i let out to get it to re-hook, I had fun, car felt great, started out with 28 lbs. air, dropped it down to 24 lbs., changed jetting a bit on my last run, didn't help MPH at all, On my second run i pulled the air cleaner, same thing, no change, overall it was fairly consistent based on the 60fts. I was pretty easy on it through the 60ft. on all runs, then layed into it after that. The MPH was very consistent, shifted around 55-5600. There using a different prep & man is it working, cars were hooking hard, i'm sure thats why i didn't fry the tires off leaving the line.

1st. pass, 2.0x 60ft., 8.3 @ 86+ 12.7x @ 108+ change
2nd. pass, 2.2x 60ft., 8.5 @ 86+ 12.9x @ 108+ pulled cleaner & spun
3rd. pass, 2.0x 60ft., 8.3 @ 86+ 12.7x @ 108+
4th. pass, 2.3x 60ft., 8.6 @ 86+ 13.03 @ 108+ jetted up front from 72 too 75 & spun

It probably has some 7's if you get some sticky tires on it

According to the wallace calculator, 8.3 1/8 mile converts to 13.0 1/4, I ran 12.7s on an 8.3, went 13.01 on an 8.6 1/8, so it must have been spinning through 1st. gear.

I know we all keep on saying get tires. But get tires.

U were definitely spinning. And the fact you arent full power gettin out of the hole is killing you


I think youll get a 1.7 60'.

When r u going back?

No telling when i'll get back, but your right, i need tires, I was worried about the stock DShaft, but was told it should hold up with good U-Joints.

Yeah youll be fine. Ive seen stock shafts on 7 second cars. Thats 1/4 btw

Thats good to here, thanks.

If your worried about it, throw some hoops in there just in case. Never want to polevault due to a failure. But just check your yolk at the trans, and the bolts and yolk at the diff. Those are the common fail points. Dont often see a stock driveshaft twist in half from power. Tires would likely get you a far better ET tho. I would think a radial would be enough, i doubt a slick is NEEDED.

As said you should be fine, your not turning it hard enough to get in trouble. Look up Drive Shaft Critical Rpm for some good read - Precision Shaft Technologies (PTS) has a nice
chart you can look at.

I really hope everyone has a loop that ever hits a track.
