a supra will do 9's with a big turbo, fuel, cams, and electronics.. all bolt on's. don't even need to touch the engine. SW drove his 800rwhp supra to 9.81.

they don't handle like **** either, but you guys are used to rx-7's so it's not on the same level.

You need every bolt on with a T78 or so and gobs of fuel along with a good computer system and hours and hours of dyno tuning. You'll probably also need some suspension work and a different rear axle.

A motor with good compression is just a given.

If your really interested in this I'm sure people will give you better info but its not worth the time/effort if your just "curious"

The difference in the guys running 9's and the guys running high 10's usually isnt the parts. Its normally tuning. If you want a car to run 9's you have to eith know what your doing as far as tuning is concerned or know someone willing to share thier "secrets" cause believe me, they all have thier "secrets" Thats why they are in the 9's

Later,
STEPHEN

If you run 9's in a Supra......your still in a Supra. Hell, you could get a Rustang and get a stroked & Blown big block put in it and be just as fast.

So you do a little more work and drive a 9 second or low 10 second RX7 and be much better looking and unique...IMO!

Also, damn near every Supra owner I've met has an attitude. Most FD owners I've met are eager to share info and more laid back..(i.e. friendlier?).

Hell yeah can we get a wh00p wh00p! Rx-7 owners are the bomb. That's why my dad is so cool . Well...was, until he sold his rx 5 years ago . Havn't seen or spoken to him since...






BTW, I'm joking :P.

That he isnt running one RP fuel pump?

hehehehe....its fun to know people.

Or that he gets "upset" when a snotty-nosed kid comes out and almost beats him down the 1/4 mile WITHOUT the kid using NOS.... Ari did though....

You could get one of those old american cars (Nova or Camaro) and install a new 427 aluminum small-block. This monster should put out around 700 hp at the crank mildly tuned. Install a good tranny and rear-end, gut the interior, and take care of the traction problems - viola' 8 to 9 sec car that is completely reliable and under $35,000.

Oh yeah, paint REX on the side...

Seriously, it would be one hell of a lot of fun to drive!

Start with an RX-3... stuff a 9" ford rearend under there, Liberty transmission, don't forget the wheelie bars.

You could also start with a 1st-gen RX-7 but the RX-3 looks cooler and already has a leaf spring suspension in the back...

Where would you want to run 9's at?? Most of these fast times were ran at sea level and can't be backed up at anything other than a few hundred feet above. When my car runs a 9 at 2400' i'll be extremely happy because that's saying something. Not taking anything away or hating on these guys....but you have to compare apple's to apple's when comparing the "fast" guys.

Supra's don't make as much power as easy as you guys think. They do make huge power....but come on now. I don't think there are many guys that are really making 800rwhp with a stock motor....but how would you know any different.....not like their gonna break their motor down to prove it. It's just a trick of the trade to sell parts(with most of the shops).

9's are not going to be had easily in any car.....some of you guys make it sound like it's just bolting in a big block and running "NOSS". Have you ever ran a 9? I haven't! I've ran a low 10....but 9's are soooooo fast! Do it then talk about now "easy" it is.

If your car weighs 2200lb with driver then you only need about 500hp at the crank to run 9.50's at low 140s MPH. How hard is it to make 500hp?

Light weight = king!

How would you build a 9 sec rx-7

Take it to someone who have done it before!

I hope that was meant for the Supra community!
Hmmmm!
Last year at every event I made a minimum of two 9 second runs which put it at 12 to 15 nine second runs, two of which was done at Palmdale in Cali. at an elevation of around 2700ft I believe. Actually my quickest time off the Bottle was done at Palmdale which was 9.58 at 141 mph!

Yes..... it is easier to make more horsepower with a Supra *but* you gonna need more horsepower to run the same numbers as the FD......weight is the key.

We're talking about street-class cars, right?

How long does those stock bottom-end Supras which are pushing over 650-700rwh last ??????

Look at Ara from Bullish racing.....he has a Supra, big-fat wallet a crew to attend every need of his and a Motec......do you know how many motors it took last year to keep him running high 9's last year ?????
and pretty sure they were not stock bottom-ends.

Don't get me wrong....I love the Supra, simply for the amount of hp it could make mainly the sound of one modified.

It's all a balance of horsepower, weight and traction and it could be applied to any car inclusing both the RX7 and the Supra.

Crispeed: I was making reference to the "Street class" cars. I know there are many who can back their times up......but there also seems like a lot who can't. I know it's drag racing......but when you blast a mid 9 and then claim your a 9sec. car but only go mid to low 10's all season......that's what i think is funny.

I think that what you run consistent is what you should claim.....not a fluke run. (just speaking in gereral)

We have cars around here that have ran a 10 once and go around saying that they run 10's. According to the rules you have to back the run up within a 10th (or close) to be able to claim the time. This is correct right?

To build a 9 sec. RX7 will take lots of money and lots of time......lots....lots.....lots....etc... I'm in the same boat right now and it's taking forever and a small fortune. I'll get there though....

The guy with the 1200 hp supra you are refering to is probably Dusty from MVP motorsports in Bridgeport.

I've heard this way too many times. People don't seem to understand that supras at very high power levels are NOT ideal for drag racing. Two reasons: Weight and gearing. At a certain point, they have to run absolutely huge turbos with huge rear a/rs in order to make power up to 8500+rpms. Problem is this step up in power peak does not match well with the cars gearing. It does not spend enough time in it's powerband. That's why beyond twins, they run high traps for their ETs. In later gears their they spend more time in the powerband. That and weight makes them wrong for drag racing.

RX-7s have a few things that help. Heavy porting/overlap gives them a much broader torque curve, while at the same time allowing for power @ crazy RPMs, and large turbos, etc. This means they can spend more time in there powerband. Weight helps too.

Hell, you could get a Rustang and get a stroked & Blown big block put in it and be just as fast.
If you have a stroked/blown BB, you better be running better than 9's

Well, if you dropped it from a building at the 1/4 mile mark you should be able to get it to the ground in about 9.1 or so. Did you want to make multiple runs?

Sorry I had to.
