Need help on what to check for the loss, or lack of power on my roadster, it is a 6 speed with a jwt intake, kinetix cats, injen ses exhaust. First time ever at the track with the car and on 5 runs I ran between 90.5-91.7 mph.

It's my first time at the drags and I was also cutting 2.4-2.5 60's and running low 15's I know I can improve a lot on the driving but the mph's seem very low, the track is 4000-4200 ft. above sea level. and for comparison a stock mustang gt was running also low 15's and trapping in the 91mph range, a supercharged cobra (03) was trapping 104-105mph.

Any help, input and opinions welcome.

 

above sea level kills you. Don't feel bad, I am at 5500 +

 

I run at West Texas Raceway Park which is a little over 3000ft. The best Ive run is 14.9 @ 94. Elevation sucks!!

 

chase350z, you didnt list your exact et's, but your speed of 91.7 corrected from 4100 ft is 96.61 mph.

assuming your times of "low 15's" was a 15.4, your corrected time would be 14.63 mph.

hope this makes you feel a bit better.

 

Thanks everyone.

I feel better knowing about other cars trapping low to mid 90's elevation does suck, I know my car has more in it, i'll probably go this weekend in hopes off better times and also get familiar with 1/4 mile racing, its different from street racing. I got a lot of wheelhop at the track and the car was breking loose even in 3rd gear... I took the tcs off but everytime shifting to 3rd I could feel that if the tires spun the tcs would act up in some way.

I'm more than probably trying to make things up due to my performance.

 

yeah dude, el paso is waaaaaay up there

come down i 10 and run with us at San antonio raceway. the car will probably trap 97 here when its cold.

plus its sooo humid here right now int texas
