1/8 mile times

Hit a local 1/8 track this past weekend. Temp was 90 degrees and the density altitude was 2700 for both passes.

I have fbo, minus inlets. E70 mix, bms flash and 22psi

The 8.0 pass I spun about 100ft out and it shifted early to 3rd also.

2nd run the car was alittle warmer on the iats, but not by much.

I really need to get some good sticky tires and launch it hard. She pulls hard after 60.

Nice runs. The MPH is there, just need traction. I'm waiting for cooler temps before trying my local 1/8 mile track. I'd love to see a 7.9x or lower pass, but I know the stock RFTs and eLSD is a big limiting factor.

What kind of power are you putting down with your mods? I'm running an FMIC/e85 tune only and put down around 410/470 at the wheels (21psi).

Any tricks to launching? 1st or 2nd at launch?

Also, edit your sig with the new time.

I believe she has a good bit more in her.. better tires and air will help alot. I think she will run 7.4-7.6 and trap 94-95 on a gtrat dat. I still have a stock different as well.

I don't know my power level. I launch in 2nd gear around 1600-1800rpms, anymore than that and it just destroys the tires.

Get yourself a set of drag radials. Will make a huge difference.
