First off i would like to say thanks to jason, mike, and zavier at the Rx7 store for redoing my engine.

I took the car down to the track and ran my new best:

R/T: .520
0-60 ft: 2.25
1/8th: 8.324@ 92.74
1/4: 12.4@ 119 mph


This is running at 16psi and with really shitty track conditions and the outside temp sitting at 90. Intake temps according to the PFC were 49.

Not too bad for my first time with street tires. I need to learn how to drive the car better, and i should be able to hit 11's.

 

not bad. What kind of clutch/LSD are you running.

 

WTF, 119 mph trap speeds with a 430whp dyno graph from RX7store. That's more like 380 whp.

 

im running a spec 4 clutch and stock lsd.
Could also be that im a shitty driver lupe

 

wow ur track speed is extremely high, i think u can hit 11's. if you work on ur 60ft then u'll hit 11's forsure. get a 2.0 ruffly and u should hit 11's. with my civic with a b18c i hit a 2.1-2.2 on the 60ft

 

Driver error doesn't matter. Your trap speed doesn't lie.

 

It does if he's not getting traction. Basing HP off trap speed doesn't always work, it's a guess at best.

 

i need to get better tires and see how much better i can get. I would also help if it wasnt 90 on the track

 

Well, even in that heat your car is making enough to dip into 11s! The trick is harnessing it and putting down the most possible before completely loosing traction(what makes drag racing hard! lol).

 

Thats true, scott ran his car that friday night before nopi and had a real shitty launch with a 3.6 60 foot and ran through at 14.4 at 117 and then raced last MM at GIR and ran 12.4 at 118. Car put down 345 whp.

 

As long as you don't let off or do something stupid, you trap will pretty much be the same........ Even if you 60 foot horribly. Only place that you'll lose a few mph is if you mis-shift 3-4.

 

or 4-5 in my case.....last week for me was
12.4 @ 116 2.0 60' over-revved 4th 8200rpm
12.5 @ 113 2.1 60' slow shift 4-5
12.6 @ 109 2.1 60' no shift to 5th...just coasted
12.5 @ 118 2.1 60' horrible 330' spinning....but yet, my best trap speed of the night and again over-revved 4th to 8300rpm

And my 3.6 60' was my car falling out of first gear and it still ran through at 117mph starting at the 60' more or less.

 

Hell, someone could mis-shift all the way through (or granny shift the whole way). You still only have a limited space to get up to speed. Traction, shifting, and throttle use all play a role in that limited space (unlike a dyno). That's why it's still a guess.
