Improving 60' times

MilesnMiles · Post by **MilesnMiles** » Tue Sep 18, 07 5:45 pm

OK guys, how do i improve 60' times? My best shot was 2.236, but i backed off as i lost traction. My best et was with a slower 60, so there is room for improvement.
The 10 second Escort next to me had 60' x 1.647.

1.570 was my best 60ft over the weekend

Impressive, but how do ya get it down below the 2's in the first place?

Power, Weight transfer, suspension set up, gearing, grip....not necessarily in that order

Slicks! Street tyres are for going to Tesco's IMO

indeed

Yes. But what if you need to get to Tescos quick? I say sort suspension then gearing, then use slicks in that order. Unless its raining - then first 2 only- helps with insurance claim.
On way back with weight in trunk, you can test 60 foot times in car park.
Just a thought...

The Darts best 60 foot time was 1.585 (No gas)

11.433 @ 117.19 mph.

4.10 gears, 28" x 10.5" tyres

Best 60 has been 1.75 @12.39-107 @SPR. Couldnt better 1.85 at Shakey/June and it was hotter day, all other things being about equal. It varies lots coz I am carp.
3700lbs +me. 28x11 slicks @14psi. (seem to wear heavily on edges if lower). SS springs. Snubber (doubtful if it touches floor). Launching at aboot 3500 on a 3000 stall. Held at 6000 on limiter. I know the 3.23 gears wont help.
Discuss.

Ohh, forgot to mention, the Dart only weighs 2938lbs.
If you think that's heavy, its got an 8 point cage, subframe connectors, 4 link suspension; so that is one light STIFF, Safe car.

No weight is cheap (sometimes) horsepower....

My best 60ft is 1.77 on a 12.00 pass @ 118 MPH

If you dont want slicks, use drag radials, also adjustable shocks, 90/10 on the front, light torsion bars and as much weight to the back as possible.
You could go 1.99 with a 14.3 et.

I'm on;y able to race occasionally, so slicks are out. I have mono leafs, but only stockish gas shocks. Reckon i'l look for adjustables and an adjustable pinion snuber as cheapish options.
My tyres are pretty skinny at 225 60 x 15 which may limit traction too.

Hey Miles 225 are wide i only have 215 x 70 x 14

One for the experts , what about tyre pressure on road tyres . Does it make and difference for us no slickers to lower PSI ??????

every little helps for cars not set up as race cars
