Can't believe the bickering on this forum over some things though, especially resulting to profanity and middle-school name calling.

Drag racing is not as easy as many people seem to think it is.

i dont take my rx7 to the track....but i do run on the street....and recently beat a newer 996 turbo cabriolet from a dig 3 times in a row.....(good driver).....which usually trap in the 115-117mph range.......i am full bolt on and 1bar on stock twins....full weight(minus spare)
I drag once in a blue moon, for two reasons... To me Straight is only fun once, turns can be taken a multitude of different ways. & It's hard on the car / Diff, Tranny, Clutch etc...
I do it once I have a bunch of mods that make me warrent going again to see if things improved....
-DC
The outcome, was on K&N Filter and RB Inlet & 11 PSI of Boost

I'm sure he's got a fistfull of 120+ mph slips, but it takes time and practice to reduce your E.T. with any given configuration.

my car stock twin stock motor made 340 rwhp (also made 298 tq =high number)..that is definately avg. i trap 116mp every time at sea level at etown. now u are gonna tell me that this guys is gonna trap 4 more mph from 16 rwhp.

1) You said stock twins don't trap 120 mph plus.
* You were 100% WRONG.
2) Yellow R-1's car doesn't weigh 2750 his car weighed 2620. His car weighed 160 lbs LESS than the car that trapped 120 mph. He made 356 RWHP on a heat soaked dyno with a SLIPPING clutch and ONLY 14 PSI. It is EASILY a 380 rwhp car.
Secondly, if it only made 356 rwhp he has a better power to weight ratio than the car that trapped 120 mph with 362 rwhp.

Trap speed
In March of 2001 I trapped 122 mph at 18-19 pounds of boost with stock twins/stock port/m2 medium/ rp fuel pump/ crane hi 6/ PFC and m2 intake. Injectors were....550/850 (for nine months) and then I switched to 550/1300's running at 100%. With the 550/850 combo I was on the ragged edge of detonation, however the engine lasted over 3 years. I ran that way for a few years and all was well.
I set up my buddies car with a similar homemade map. He has almost the same combo but a ported engine. Recently he hit 123 mph @ 15.5 pounds of boost.
We hope to run it at the track soon after we get the T2 LSD in it and some chrome axles. We'll probably need a different clutch too because once it hooks with that kind of power the centerforce probably wont hold.

bottom line is that 120mph is attainable on stock twins but I've been embarrased when I'm at the track with other FDs in most cases. I usually see 14-16sec times and 13s are great! Heavily modified twin RX-7s here in town can't even hit 12s. I got 12.8@112mph on 12psi with the pettit ecu over and over once I put on the midpipe I never got out of the 12s again and this was with 2.2 60 times. I can imagine that my trap would be upper teens with a pfc and tuning along with 15psi. However, only with ~380rwhp with a single have I been able to make it into the 120s. I usually get 120-121 and my best is 122. I guess you could say that the turbo takes longer to spool up so that's why my trap is lower than a stock twin cars trap would be with the same hp? As far as I know these high traps on twins are done on **** non seq so that cant be the case because they get full boost after large singles do and coming out of the hole with a 1.8 60 time Id say the spool is there and im making more power at every rpm above 3000 any way than twins. You guys are talking about top of the notch setups with the twins to do that its proabably 10 ever that we are talking about out of how many who mod their twin cars and have been to the track!?? hundreds would be an understatement. I plan on trapping near 130 add or take a couple next time the track opens but it's certainly with a very worked car. I'd be very impressed and a bit jealous to have someone next to me with a bunch less money in thier car trapping 5mph less. It would be a good thing though to raise the bar and have someone to go against because I feel this is lacking with the FDs today and that they are on the way out because of the owners
You're including modified stock twins? Well then I hit 125mph on non-seq worked stock turbos. I thought you meant stock turbos. The other guy who ran a ten did it on actual stock turbos I believe.
Surge, Nonsequential stock turbos with the same open exhaust will spool faster than a large single turbo, less rotating mass relative to distance from the shaft.

and not saying i'll make an awesome run, not saying i wont, just saying that just because someone doesnt crack 13.1 in a car thats supposed to make a 13.1, yet finishes in, say, the top 5 at a track or autocross event, doesnt mean he sucks at driving or racing... but i guess there are alot of other variables as well

. Before you order, shoot me a PM. I may be able to help ya out.Also, what track are you guys getting all these kick-*** trap speeds at? Etown? Next time I would love to tag along. Best on my stock twins I could manage was ~114, this at a track with an uneven surface and right next to a river in Podunk TX......
I'd like to see some slips of these amazing feats... and when you say stock... you mean just the turbos... not the ecu fuel rail etc... cause mine was stock stock... fuel, turbo etc... other than the listed changes.... which is again no big feat, but it's not exactly "Bad Driving" either....

If you don't want to spend $840 for Rotary Performance's 300M axles, try The Driveshaft Shop. They have 300M axles for the FC & FD for only $550.
Also, what track are you guys getting all these kick-*** trap speeds at?
