when at the strip last week i was running the 1/8th in low 9.4's and one 9.39 at 75mph.

but i was only get 14.6's and 14.7's in the 1/4 at 93 mph. soes this seem to be lagging on the top end???? i would guess that 9.39 would be low 14's in the quarter.

 

Pretty much what it should be. I find this chart pretty accurate.

yeah, that is about dead nuts on. the 9.39 run i ran 14.650 in the 1/4. that chart is pretty good. thanks a lot.

i guess im going to have to get a little more power and lose a little more weight

 

my friend ran about 9.15s in the 1/8 mile and did a 13.97s, 1/4 mile.
The charts says a 9.15s should be 14.27s.
I guess it is somewhat accurate.

 

I've look at different time slip and it was pretty much dead on. Of course, having two boost setting or having big traction issue will affect your 1/4 ET. If I check a very old slip, I've ran 9.81 on the 1/8 but 14.54 on the 1/4 instead of 15.29 according to the chart, probably due to my 2.55 60th. If the chart had also the MPH, it would be even better.

My best is 12.39 and I ran 7.98 on the 1/8. Can't be more dead on than this.

 

whoa, way accurate. My best time up here in CO is 12.483, and my 1/8th was 8.077. Holds true to the 100th second.

 

you also have to figure in the tire size and gearing as well. Because I have seen many GSRs lose to LSs in the 1/8th but beat the LS in the 1/4. First 1/8th deals a lot with traction and torque. The GSR is better in the 1/4 because it lacks some of the torque of the LS motor but has the better topend and gearing for the 1/4.

 

Nice chart, very accurate.

 

i ran a 9.3 at 77 and a 14.4@81 becuase i let off way before the end the pas before i did like a 14.2@98 and i had a even higher 1/8mile time

 

i think you having a built motor and a 4.78 fd may have something to do with that. you might be able to to hit 13.9's with that mph.

 

pretty close for my, doesnt have the 60 foot times they kill me
