How to turn a 12sec fd into a 13sec fd
http://cs.widener.edu/~epanek/Rx7tt-13.mpg
13.4 at 118.
Nuff' said. apologies to anyone who ever launched an rx7. in my defense i got to the strip at 8pm and didn't get that run in till 10:30, the only run of the nite. constant rain in the NE held everyone away until last friday and when we finally got a break it was packed, thats cecil co. , MD.
MODS
pettit intake
pettic cc2 IC
KDR ported engine
light flywheel
act hd clutch
ntech hi flo cat
rb dualtip exhaust
power fc, set at 13 lbs, or .9bar, only hit .85 on that run
tires were s-03s at 34lbs press.
also b&m short shifter, eibach springs, think thats about it. dave at kdr says good for 350rwhp or so. dynoing for hp on 21st.
anyway there it is fwiw

i live 20 minutes away from cecil co. dragway... it's not too bad, but there is always a ton of white-trash-wanna-be-thugged-out-ricers there, and i really can't stand going...
anyway, get a nice launch in there, and with that trap speed you have, we'll be seeing some pretty nice times
good luck!

118 trap is good for atleast a mid-low 12 sec. run, easy. Just work on the launch and you got it, nice run.

That is an amazing trap for boost and mods...simply amazing...i would think more along the lines of 110-113!!!

Launch/tires is everything with our cars at the strip. Once you have it where it makes the power down the track (which you do), then get some DRs or ET-streets and perfect the launch.

MPH is good..... someone is catching up to boostn7!
if you get et streets, etc be prepared you may snap an axle or break your diff, etc......... but it will drop atleast one second or more off your ET

i'd like to get at least one run in the 12s but beyond that i'm not a hard core drag racer, just want to make sure the car is as fast as it feels. the turbos are vaguely recently rebuilt <20,000 miles on em, ported wastegate...saw some local guys in the thread, any suggestions where to run and actually not have to wait 2.5hrs? atco, etown?

i ran 12.0 @ 118 shifting slow for comparison!
how far away are you from www.islanddragway.com ??
that is gonna be your best bet for getting the most runs in. on a FLUKE at etown you will get more than 3 runs.......... anyway. if you are gonna go let me know and i'll take a ride... fixing my hydraulic problem as we speak i hope!

i would say a 118 trap is more indicitive of an 11 second FD.
Maybe not quite 400rwhp to go that fast. Pocket dyno would tell you......

about 100miles from island dragway.
i was surprised at the trap too, hope it wasn't a fluke or messed up timing gear at cecil....
any launching tips? my 13.2 i got (before ic, boost, tuning) with massive and painful wheel hop. higher revs and dump or lower revs and slip?

i drove streetdreamzny FD on the track.... my first time ever driving a sequential FD... i ran 13.5 @ 109 or something like that. i had to beat my friend in his 240sx with sr20det anyway i did a burnout then launched at 6000 rpm dumping the clutch on street tires.... i also drove shadow27's at the track i ran 14.3 missing 3rd gear.... his car is evil. i would say try slipping it its bad for your clutch but it works REALLY well
