....needless to say, I'm a little rusty on the reaction time (that, and the CVT is a slow responder)

too bad the local track is an 1/8th MI.

Good data. I assume you were using the manual shift mode and not sport drive. If you have DSC did you try it both on and off? I think it might slow your launch when on. Finally, what tires were you running? Thanks.

[Electrc109]

Well, I dont have DSC. I used the sport mode and the steptronic mode (w/o shifting, I simply let the computer do the shifting) I felt no difference between the sport and steptronic modes. I should have taken note of what i did in each run. the 12.??? time was when I tried starting in 1st then putting it in sport mode. unfortunately I made the exchange in a messy fashion so i lost time...


The tires were Continental 15/175/65 size tires...i put the PSI up to 40 on the rear tires to reduce rolling resistance, and left the front to 32 since there would not be a traction problem with the boring launch

My car ran a 15.1 1/4 mile with a 2.41 60 foot.....hoping to go 14.90 this Friday night

[Electrc109]

minime s - considering the fact that I have a CVT, thats not as much of a difference as I'd expect!

[minime s]

My 1/8 mile times were 9.85(that would be a pretty big ass whoopin')

[minime s]

and the 1/8 mile MPH was 74MPH.......I don't know how long you've been drag racing, but your talking major car lengths here......too bad we couldn't go to the track together......have fun...

[suprchrgdmini]

hey minime s i think the cvt would take you.

[Electrc109]

well, I havent drag raced in 2 or 3 years, and i dont have that much experience, but I'd say I could shave .5-1.0 second off my 1/8 mi time if I can figure out a way to really launch off the line....

[minime s]

I can't see that car having too much wheel spin. Taking 1.0 off the 1/8 mile I can't see......

[Electrc109]

no wheel spin....the computerized tranny won't allow it

[dukesantos]

I agree, I don't think you can spin your wheels like an S can off the line. You could try bringing the rpms up to 2500 or so, holding against the brakes, at the lights for a faster launch. The next big improvement would come from wider, sticky tires, like 205/50-15 Kumho or Hoosier. We autocross and track (but no drag race yet) our Cooper, the right tires can make a big difference.

[Electrc109]

if I don't have a problem with traction, putting bigger tires on my MINI will just add rolling resistance.

When drag racing, I put my right foot to the floor, with the left foot on the brake, once the yellow light goes on, I let off the brake for my launch. When doing this, it is still rather lethargic (the revs go only up to est. 2700 in this manner)

[minime s]

Do you have ASC or DSC ? If you do, you need to turn it off.......

[Electrc109]

No, of course I don't. I learned how to drive a long time ago instead.
