My High Comp Turbo 1/4 mile
Heres a timeslip from my first ever time drag racing, which happened to be in my rx7 with a high compression turbo engine in it.
Details: Totoally stock 6port motor with a T3/T4 hybrid turbo (not a stock s4/5 hitachi) with a Slightly larger exhaust housing and very marginally larger compressor than a stock S4/5. Had a rather small stock supra intercooler up the front cooling the charge air and a microtech fuel only comp running the whole shoting match.
This run was on 4psi, as you can see I only managed a dismal 14.8 with a pretty pathetic 60ft time because of wheel spin probs.
The next run I did at around 6psi after fixing a few probs, I kept up pretty close with another FC that had just run a 13.8, until about 3/4 track when I let off after hearing a strange noise from my engine (turned out to be nothing). So I got a crappy time for that one.. (15.xx....)

Yah, unfortunately a faster RT doesn't equal a faster 1/4 mile time.
It does help on heads-up racing though.
Definately would be better with a little stickier tires or a better launch. They say that for every .1 you take off your 60', you are .2 faster in the 1/4.

just quickly since i don't want to clutter up this thread to much, I used.
Turbo
Custom exhaust manifold
Supra intercooler (now replaced with _much_ bigger FMIC)
Lots of shiny stainless steel 'cooler pipping
FD fuel pump
Engineers labour cost for various things....
Microtech fuel only computer
Some misc oil lines/fittings
Some misc coolant lines/fittings
Loads of other crap i've probably forgotten...

Since this time i've now rebuilt my motor, it's currently running as just a streeported N/A motor, still with the same 9.4:1 rotors, while I run it in, another 1,000 or so km's...
After that i'll decide what turbo i'm going to put on it..
Probably a much larger one than last time
And yeah your right it was alot faster than that before the rebuild anyway, never really got a chance to take for another run down the strip though..
Another month or so and I should have another time slip to put in here though
