track times- I need help

**jrc1122** · 04-06-2008, 05:28 PM

What the hell am I doing wrong...

2.2671 - 60ft
5.9819 - 330ft
8.9685 - 1/8 ET
82.58 - MPH (1/8th)
11.5122- 1000 ET
13.6609 - 1/4 ET
104.43 - MPH (1/4)

I can't launch for sh!t. I either spin way too bad, or bog.

Tires are Sumitomos @ 24.5 psi - with only about 2000 miles on them.

I launch at around 1500 rpm- slipping the clutch while quickly rolling on the throttle (OBVIOUSLY NOT DOING IT RIGHT THOUGH!)

My mods are in the signature ( I have a Pro 5.0 shifter but it isn't installed yet)

This race was against a WRX (not STI)- but it seemed upgraded- who ran 13.5059 @98.40 MPH

U need drag radial first of all. It will help cut down on your 60ft. But other then that you look like you are at the right speed and times. I have a slightly different set up and I am running 13-13.1's all day long. You will need some more mods to get more hosepower. Start with the drag radials first.

thanks- but there was an auto 98 Z28 w/ 155k miles on it with a stall converter, and catback that ran a 12.9x-- so I know I should be running better than a 13.66

not to mention out of every LS1 there (that I got a chance to see run) I was the slowest-

If my 60 ft time was a 1.9 - I could be 13.3 or better I think.

The WRX ran 13.5 @ 98 mph
I ran a 13.6 @ 104 mph

Notice anything that stands out-- Yeah I crossed the line going 6mph faster than him. Proving I should be running faster times.

I agree- Drag radials will help alot.

Autos have the benifit of "torque multiplication" through the converter. He may also have changed the gears in the rear. Rear suspension is another big key to our cars...get the 60' down and it will pay off at the big end.
BTW, if you put the DRs on, don't be suprised if your next mod listed is related to your rear diff.

Good luck at the track!

How quickly you shift can make a big difference as well. I know in a few of my 1/8 mile runs I have changed shaved off .2-4 seconds off just because I shifted faster and a little more aggressively. Of course I have also lost time before from shifting to hard from 1-2 and breaking the tires loose.

With street tires it is hard to get a reliable fast 60' time. I am still struggling with breaking the 2.00 mark (come close with a 2.02). For my best times I have had to little haze the tires to keep me out of the bog and up into my car's power band, but still not spin them so much that they get blown away (usually launching at 2750 or so, and do a quick release of the clutch).

Everything makes a difference. Track conditions, mods, weather ect... You really cant go off of what other people do. This is the fun part, trying to do better every time you go out. The drag radials should be the first thing you change next. Then you will need the suspension mods in the rear. Goos luck.

A friend with a 00' ws6 and only flowmaster catback at the time, ran 13.4's consistantly, and a best of 13.2. I can get the slip, but his 60 ft sucked, but on the 13.2 run he didn't launch at all, just started out normally, but no spin.

I'm gonna head to either cecil or atco this weekend, weather permitting, and see what I can pull off

Good luck!
