new best 9.68, 70gtq works!

Based on mph you picked up 47 hp at the rear wheels, average, assuming 3500 lbs going down the track (758 vs. 711). Looking at the turbine wheels it's easy to see why the GTQ is harder to spool :). Great times, by the way. The 9.68 is right on average for the mph, but your 10.01 was a little off, 137.00 mph on average is a 9.90. [average et=1356/mph, average rwhp=197*weight/et^3, and usually it is best to use the mph to calculate the et that gets plugged into the hp formula]

the p-trim on the left was originally from john craig i believe.
 
the car weighs 3600 with me in it. the 137 was last year without a t-brake and a crappy 1.59 short. good little turbo that p-trim. i think i will put it back on for street driving.
 
I thought that Bumford guy promised 10mph with the GTQ? :p

I'd be pissed. :mad: ;)

Nice job and congratulations on your times. :cool:

not quite 10 but could probably p/u 5-6 mph. i only got one full pass and the turbo still wasnt maxed. launch boost was between 15-20psi. 10.5x28 m/t slicks. trap rpm is in the 63-6400 range. still using an old FAST b2b. nothing special about this combo. it just works:)
 
Damn thats flying! Well i wish to do as well as you were doing with your 70 ptrim. Just have to get the FAST hooked up over the winter and take it from there :eek:

its not that hard, you have the hardware so to speak, once you get the tune right just crank the boost:)
 
timing is 22 through the whole run. this set up works better with conservative timing.

thanks louie, i know that article all too well. i analized it many times to help me decide what new turbo to buy. the 70 gtq makes a ton of power.
