Not gonna happen on a stock Supra tranny (6spd. or auto) That being said, your gonna need to run a Jerico or G-force tranny and make 700rwhp+. Thats been done only by a VERY select group of people. Steve Kan nor Ari Yallon have made this kind of power so that gives you an idea of how hard it is. Demetrios K. has made this kind of power and ran a 9.20@153mph, but that was a 2500lb car which yours won't weigh. Sorry to rain on your parade, but your not going to run this fast, unless you want to go to "full race car" route.

My RX7 will be tuned by someone who has made a little over 700rwhp on a couple different 2 rotors. If i'm not mistaken Adam S. was making over 700rwhp quite a few yrs. ago.
My car weighed in at 2400lbs. a while back and that was after the full chromoly cage. It was missing a tranny and misc. parts so i'm hoping for around 2600lbs.
If i can't do it with the rotary i've a got a nasty little project to try and wedge in. It's still a Mazda motor

If you really want to run high 8's and drive around to car shows and what not's on the weekends then......
Drop your car off at either Jerry Haas of Jerry Bickel for a full tear down, acid dip and 7 sec. legal racing cage. Also tell them to make it street friendly and use a 10.5" wide tire. They can make a world class full chassis car.
Next, you will want to shoe horn a Tremec "world class" TKO 5-speed or a built Coan TH-400 auto tranny w/ pro tree transbrake. You will want to run a slipper clutch that yoiu could buy from , chilton, Mcleod, Hays, Ram, and hve to custom adapt it too the Rotary engine.
If I where you, then I would opt for a 20B with big street/race port and a Big *** ball bearing turbo w/ a water cooler system. Use dry ice in the water when running high boost. Run eight or nine injectors on the motor and two big street pumps. Run a motec or haltech EMS set up for a 3-rotor and all those injectors ( you may get other reccomendations by your engine builder/tuner. I would find out who does Abel Ibarra's engines, or probably try RX7.com. Acosta Racing is in the Northern east coast and builds high horse 3-rotor drag cars too.
Run a carbon-fiber hatch w/ lexan rear window to further your weight savings, but try your best to keep as much weight off the front as possible too.
Trust me, there are tons of guys in the US running high 8's in domestic Fuel Injected hot rods (Lots on stock suspension arms and 10.5" wide slicks). Their cars weight more than an FD too. All you need is 700+rwhp and 2650lbs. with a chassis that hooks real well and a tranny matched to the power range of the engine. On the street you can drive around de-tuned to 600hp and eat everyone alive.
Brad Brand is a buddy of my friend here in ATL, GA and he owned a dyno shop tuning late model domestics. His car was a full steel body 89' mustang that ran 7.20's on 10.5" drag slick's. he had the 10.5" tire record a few years back. His trap speeds were in the 190's. THIS IS TOTALLY FOR REAL. I am sure you could find some info on him on the net somewhere. His shop was called ATLANTA CHASSIS DYNO in Swanee/Duluth,GA. His mustang was black.

You'd have to run over 35lbs of boost on a large frame turbo and C-16 isn't stable that high. Sorry, you may want to try a 20B.
Like i said....if the rotary doesn't work then it looks like a V6 will be in the near future. 20B isn't completely out of the question but the V6 is looking a little more promising.

Hey ditch the rx7 if your shooting for high 8s or low 9s. If staight line is what your into power to weight is your main concern especially if you want it for the street. I've got a 1971 datsun 1200 that weighs under 1900 lbs with my fat *** in it. It's mainly a strip car but yes I can drive on the street on limited duty. And I'd like you guys to check this site out http://www.mazdarotary.net/ look in the updated records page under 'Original' Untubbed Top Twenty (Rotary Only). In the top 10 there is only one rx7 and it's a series 1. You look at the corolla that runs 8.54 thats on leafsprings untubbed so yes it can be done and no I wouldn't do it with a RX7 third gen. Hey I'm not a rich man I'm bulding my car on a budget to run low 9s possibly high 8s for under $25000 and yes I will do it. It might take me longer than most folks but it will be accomplished and I do all the work on my own. It's hard to build a race car and raise a family at the same time.

13btnos: Like you, i've got a goal. Money is not too much of a concern as i've already crossed the $100k mark a while ago. I'm not bragging......just stating the facts. I've set myself a goal and that is to run an 8 with my RX7. It doesn't have to be with a rotary but that is preferred. I'll push it as far as i can....then look at other engine options.
One thing that i've got on my side is a really good tranny...TH350..... and a really good converter company. My car is very light and i've done alot of things with the suspension that noone else has done with an RX7.
My car is going to run 8's in streetcar trim.

Update as of last nights races: My friend Daniel Donofan (94 Supra)ran a 9.40 @ 148 with 745rwhp and Dana Westover (93 Supra) ran another 8.9 @ 156 with 870rwhp. We were hoping to beat Marko's time of 8.45 and would've done it on the last pass but something happened a little past half track. Dana let out of it and coasted to a 9.1 @ 130. The incrementals put the pass in the low 8's somewhere in the mid to low 160's.
That's racing! Looks like everyone will be able to keep their titles for a little longer in the streetcar category. It would've been really nice to hit some low 8's and possibly even a high 7 but it'll have to wait.

From this thread I can see that Bench racing hasn't changed much in 30 years....
Anyway, I was just doing some measuring on my FD and I realize that I can install this JT8D that I happen to have into the car with relative ease.
At 18,000+# of thrust w/o afterburner, this car will have NO traction problems (except for maybe some minor push in the corners) and will literally "blow away" any competion. I'll be smog exempt--even in California--and if I install a quite kit I should definitely be street legal by someones' definition.
Oh... One more thing: I'll need about 24 or so of the supra or walboro fuel pumps to feed this thing... And maybe some big brakes, too.

What classifies as bench racing? A bunch of car guys sitting around talking about how fast they'd like to go? If that's bench racing then it'll never change and could never change. You'd be suprised as to what you can learn from people who you didn't think knew anything.

Okay, look, if you have a relatively unlimited budget, forget three rotors and go for four. I'm sure you can find four-to-six-rotor motors on the 'net, for a price.
the 787 used the 26b four-rotor with RPM-variable intake stacks and made 700hp. naturally aspirated.
Four rotors is still rotary powered, and with a turbo, should be able to make 1000 hp easily. Even if they don't sell them off the shelf, with a big enough budget, you can prototype a four-rotor (make sure it has a billet rotor shaft) and change the import scene forever. Especially if you make it so that an affordable four-rotor is available for more people after making the prototype.
And 9s 8s or even 7s should be available, and who knows what else. 1500+hp NHRA Pro Stockers (or gasoline funny car as they should now be called, because their bodies have nothing that I can tell that is stock on them now) are making sixes. No reason a four-rotor mit der turbo couldn't get there. Or five rotor. Or six.

Not doubting you, but theres only been about two people who have made over 700rwhp on a 2 rotor, all turbo. So how do you think your going to make that much? Actually, yes.....lol.....Im doubting you. Your not going to make 700rwhp. Even w/ N20 it'll be a stretch. Not on C-16 anyhow. You'd have to run over 35lbs of boost on a large frame turbo and C-16 isn't stable that high. Sorry, you may want to try a 20B.
