i tested my time in the 1/4 mile today and ran a 13.4 at 114mph.. that mph just seems to high to me? anyone else agree? i did have a horrible launch but i'm just learning how to do it.

what do you have done?

tight2000ss

lid, kn, shift kit, flowmaster.. my question was the mph.. i think the time seems right considering the **** launch but the mph just seems really high

Red Shift

If you had a **** launch the mph is a hp indicator. Your et seems low

MPH is WAYYYYY to high. I'm guessing you used a GTech instead of acutally running at the track.

13.4 @ 104-106mph is about right for your mods.

tight2000ss

yes its a gtech but that is the mph i was at when the 1/4 was up. i did it a number of times and every time it was right there. i watched the mph and the 1/4 is marked out. so maybe the time was wrong??

Trap speed is a calculation, not just the mph you're at when you cross the traps.

G-tech reads high. It's fairly accurate for ET given a good setup, but tends to always read high on the trap speed.

trap speed is the calculated by a "speed trap", if you havent guessed. there is a marker 60 feet before the 1/4 mile mark, and another marker at the actuall 1/4 mile mark. it uses the time it takes to drive that 60' to calculate the "trap speed". thats why its called TRAP speed and not just speed.

it is generally accepted that the g-tech's 1/4 mile trap speed reads high.

if you have a newer model that allows for pitch factor adjustments, what do you have yours set at?

perhaps the most important attribute of the g-tech is it's CONSISTANCY. you can do mods to the car and see if it reads faster


i've heard from a few people that it can be dialed in pretty well at the track and the 60' will read within .01 and the ET will read within .1

alright thanks guys. i knew the time seemed right on. with a better launch i think i could get it to 13.2-13.0 i mean it was that bad of a launch... lol. i need to practice

well what was the 60' ? the g-tech should have read it lol

which one do you have? old style or a new style?

blkZ28spt

Old style G-tech, like I have, doesn't give 60's.

tight2000ss

yup its the old style with no 60' time.
