i should hope mid 12's would happen at 270. 0-60 depends on the rear a 3.6 could get 4 or less with that much given how light we are and the headroom of the gears. a 4.3 would take carefull driving to breack less than 5 for sure 1st is to short in that case i would start in 2nd given your clutch can ahndle it.

According to my Gtech Pro RR, today my best 0-60 was 5.682sec.

2.171 60'
9.120 1/8 mi @82.32
13.933 1/4mi @ 103.83

Stock: 7.616sec 0-60
2.518 60'
10.363 1/8mi @ 72.14
15.797 1/4 @ 91.85

Why has the car so bloody low gearing anyway ?
You get to what...120mph and you kiss the gears goodbye.
Oh oh....now somebodys gonna try and fit a 6 speed :eek4dance

the 6spd has even lower gearing. The car has low gearing because the stock motor 100 hp would not move w/o it.

sams, how much hp are you putting down

I was kidding but I have seen some local hillbillies do something similar using a civic wagon awd system. It didn't work very well. Duh.

Not sure, GT2554 @ 7psi. The Gtech said I'm at 152hp and 133ft lb

Amazing numbers for a T25@ 7psi!! :eek: :bigtu:

I can't wait for mine to be completed!!!:cool:

traction limited FTL

I would more realistically look at a 220hp miata, 270hp is a huge step excluding the fact thats its a 50 hp hop. When your running 270 your definitely talking about danger to tranny/motor/clutch. So unless your willing to work on those components, I would shoot for 220.

0-60 = 4.952 seconds on my G-Tech Pro.

This was my infamous "test run" before the real thing (when I got a ticket for going 114 in a 55). You can look at this datalog to compare my 200 HP Miata with my mother's 1999 bad ass automatic Vette (the '99 was one of the fastest production cars of all time in case you didn't know).

FWIW, the 1/8 mile time on the G-Tech is pretty damn close to what I run on the track.

The jump from 220 to 270rwhp is huge. 220rwhp is a very nice T25 setup or a modest T3 setup; 270rwhp is a GT30 or a big GT28 series, standalone fuel management, and serious stress on the diff and tranny.

ahh thanks for all the info guys!
