I run all seasons and those are my 60' times with them. 380 treadwear IIRC.

For the record all of the manual transmission drivers who achieve 1.7's or less at my local track do not use launch control. They also tend to win 1st place, I don't run launch control either. I know that my opinion is in contrast to the general consensus here though.

Launch control is nice because it allows you to build boost on the line. With 380tw tires that's useless because you will blow the tires off. With slicks it's a different story.

You can also do things like ramp in timing and boost after launch.

Yeah, I hear you.

I bet Pat has some good 0-60 logs and 60' times, his car pops wheelies.

I think it took me a month to read his build thread. I bet his 0-60 is killer.

Playing with FM's gear calculator, it looks like you can get to 60mph in 2nd gear in every stock 5 speed gearing setup. That shift to 3rd is definitely killing me.

Interesting, I used the calculator for 3rd, my logs do look like I have barely finished shifting at 5100. I didn't even consider 2nd.

Looks like I reach 60 MPH at 6650 RPM in 2nd.


2668.822-2665.627=3.195
This puts me insanely close to 3 seconds flat on a well prepped surface with low pressure in my all seasons, so I started a little earlier.

Last time I was at the track I ran a 1.68 60' time with a soft launch (8 psi on launch...) I need to work on my car and put the new diff in the car. It should be 60' in the 1.5's with the new diff, launching with more boost. I'd like to get it into a high 1.4, but that's a goal for after the car is in the 1.5's!

0-60mph times, probably low 3's. It's not a sub 3 second to 60mph car right now, but should be with the new diff and a harder launch.

I need to go work on my car....

Just checked my log from last night.

Dang, you got me beat big time. What tires are you running? What whp?

The best I've logged so far was a 4.188. Feeling pretty slow now.

I'm wondering if vteck logged wheelspin, 0-60 in 2.8s is really, really, really fast. I can't do that on radials with a trans brake.

vteckiller2000

Rs4s. I logged a tiny bit of spin going into 2nd but I didn't hit 60 until right at the limiter in 2nd. Pat I'm at 350 whp.

BTW that's from the log at the track. I can't come close on the street. Spins all the time.

Was this at a drag strip? What was your 60' time if so? What gears/trans/rev limter puts you at 60mph at the limter in 3rd? Did you launch in 2nd gear, or do two gear changes in that time frame?

vteckiller2000

iTrader: (4)

Yes, I was at the strip. 1.7 60' and I launch in 1st gear. I shift to third gear right at 60 mph. 7400 rpm limiter with 6 speed/3.909 gear.

Thanks. What was your 1/8 mile ET and mph if you don't mind me asking? I ran a 1.68 60' last time in the 1/8th, 6.93 @ 103mph and I didn't think I'm below a 3.0 0-60 time.

vteckiller2000

iTrader: (4)

7.492@95.74 mph. You're more than welcome to check my math, I can post the log. You are certainly lower than 3.0 sec.

Sure, post it up! I need to hook up VSS for datalogging on my car. I just assumed I'm in the low 3's.
