Default Times with mods.

Well I went to the track last night(ozark raceway). Starting to keep a record of anything I do to the car and see what kinda of changes it makes.

The car is a 2001 Z28, all mods were done by previous owner.

Car is set up with LS6/4L80e with 3000 stall, Strange 12 bolt 3.42 gears. Full bolt ons.

My best time was
1.935 - 60ft
12.45 - 1/4 @ 111.0

Rear tires are 28x11.5x15 et streets, this combined with my 3.42 gears is what I think is killing my 60ft times.

Car has 101000 miles, motor 76000.

So my next thing is a good tune up. Plugs, wires etc...

Will keep you posted.

Tim.

P.S. I put this in this section to get my 12 sec. sig. thanks.

I think thats to much tire for a bolt on car, 26s are good enough.

Good time though

Going from a 26in tire to a 28in you are losing abut 15% of your torque. If my calculations are correct. The reason I am running a 28in is because the wheels and tires I bought off of someone on ls1tech. So for now they are great ginnie pigs.

I am in the process of building a 408. But before that I want to try some different conbinations and play around with the tune and such.

U no longer have 3:42's w/ a 28'' tall tires there more like 3:08's but 3:4's are the perfect gear for a A4.

Ok finally with the weather permitting I made it back to the track.

Air really sucked. First time out a 12.7, and went the best of 12.58.

At idle the car almost seemed to have a slight miss, but running down the track it felt very strong. so going to have to find out what is going on there.

Next step is throw some N2O to it.

Will post video later.
