new 17" ET streets 1.67 60's

[xblownx]

went to the track wed and figured out how to get them to work best, 2nd gear burn out approx. 6 sec , 13 lbs of cold air press, 5000 rpm launch, results 1.67 60 foot

mods 2.9 upper, bbk lomg tubes, 4.10's, JMS tune

that 60 foot is awesome!!! is that the best launch of the day or was that your starting point?. the whole 6 sec burnout seems like a little overkill, but if it got you your best time then who cares, right! anyways id like to hear your times from other pressure and launch rpm combinations.

 

[xblownx]

my worst 60 ft was 1.79 , that was at 11 psi cold I dont normally spend that much time in the b.o.b. but the tires were brand new and I figued I'd get them to work, normally I do about a four sec. b.o., I notice you run a wet kit, what type of nozzel are you running and did you tune the car with it on the dyno?

Awesome. That was on the stock IRS correct?

Congrat's!

 

[xblownx]

yes, stock IRS with 00 cobra R springs

Nice 60 ! Are you still using the stock clutch ? Notice any slipping in the clutch ? A local shop has a set I was considering buying .

 

[xblownx]

stock clutch, no slipping yet, if it starts to slip it would happen in third or fourth gear, thats when you should first feel it start to go..

What kind of times are you running in the 1/8mile & 1/4mile??

I just went to the 1/8mile track with my M/T ET Streets. The best 60' I could get was 1.70, but the track wasn't prepped well.

I too have 4.10's and me best pass was 7.33 @ 97.19.

your 1/8 mile times are extremley low compared to your 1/4, my 8th times are 7.53 at 93.33 with 11.67 at 120.16, you might be losing your clucth. with 8th times like that you should be running 11.00's

that 1/4 mile was a previous best, haven't been back to 1/4 mile track since mods.
