Re: 1/4 time question?

By multiplying my 1/8th mile time of 8.76 by 1.55 which is supposed to be your approx 1/4 mile time, I came to 13.55. I dont think thats too bad considering I have 2.73 gears still and have done nothing to the tuning, heck i dont even have an lt4km.

with a cam, headers, torque convert, and gears I ran 12.05@113.29 with a 1.700 60'. I'd say that was pretty damn good for just those mods.

Well I have those mods sitting in my room ready to be bolted up and in the motor, PLUS 125 hp of happy gas.

I'm running on some Kumho's. They are okay tires, but nothing to call home about when it comes to traction. I hope to run it again once I get some DRs and Torque Arm.

That link will give you a little bit more insight on how to launch better.........and no do not manually shift.....definately let the tranny do the shifting for ya.

Don't Look Back - It was a cool night on wednesday that I pulled my 14.2s, not sure what the humidity was though.
When I had the CC305 and hooker shorty headers, no stall, and street tires, my best time was 14.14@104.1. But I think I had some issues that were never resolved, plus a 2.466 60'. Oh well, its all better now

Re: 1/4 time question?

Get new wires and plugs when you add your headers. Make sure the car is all tuned up well. I was running 13.6 w/ 2.0 60ft with Intake, exhaust, & headers on street tires. Also make sure you do not have a lot of gas in the car. Gas = about 7-8 lbs/gallon; 10lbs = about -.1secs in the 1/4.

100 pounds weight reduction equals to about -.1 seconds reduction in ET.
10 = -0.01

For what it's worth, the best 60' I could pull on street tires was 1.966. That was with a 2400 stall and stock 16" tires. Without the stall, the best 60' my car has done was 1.999.

This is a 3.23 geared automatic and those times were when it was almost stock.
