who's the fastest 1/4?

who do you guys think would win 1/4mile and also 1/2 mile.

a 93 mazda rx7tt(only2600lbs) or 04 sti?
1/4 and 1/2

there are many places where you can get 1/4 mile times for these cars in stock form. I havent seen them but if I had to guess I would say sti 1/4 mile and RX7 in 1/2. Modified I would go with rx7 all the way.

A regular RX7 (all 93's were twin turbo) the STi should have it no problem in the 1/4 and should still be in front at the 1/2. An R1 or R2 would be close through the 1/4 and should beat an STi through the 1/2.

Why?

why do you say the R1 and R2 are faster than Touring in 1/2 mile?

the sti will definately beat any versions of the rx-7 in the 1/2, and in the 1/4, especially in the 1/2

You seem so confident in saying that.

cause i am smart guy. any versions as in the only ones that we got 93-95.

Well I wasnt aware what year Rex's you were referring to, and I never said you weren't smart.

Do you mean as in record? Who knows. Prolly alot of guys who are capable of breaking the record that dont run.

sti is toooooo heavy it will beat the rx-7 quarter mile due soley to AWD, but top end... thats what the rx-7 is good for, plus its light weight.

you could have just asked, smart one :smile:.

Are you forgetting 1st and 2nd gen. RX7s, they werent faster but they were other versions that we did have.

remember what tegdude said?

a 93 mazda rx7tt(only2600lbs) or 04 sti?

he said 93 rx-7, so that means he was talking about the fd3s version. so any versions of that yr we got.

Ok my bad, but thats not what this discussion is about anyways, I want to know what the basis for his thinking is that the sti will beat an rx7 in the 1/2 mile. I'll admit I havent seen numbers from either these cars, but if you consider the weight and gear ratio of an RX7 you would make an educated guess that the RX7 would beat the sti at least in the 1/2 mile if not both. You see, horsepower doesnt mean much. I have 180hp in my jdm b18c hatch, and I beat (what is it?) 260hp? mustang gt's all the time, 1/4mile, highway, autocross, you name it. Yeah the Sti will have a better launch, thats why I think it would win in the 1/4 mile, but maybe not even that, maybe it would only win the 60ft. I dunno, all these are my own educated guess.

i just found a website with a bunch of stats. First the 04'sti has 300hp-300tq. and does 0-60 in 4.8 and 1/4 13.36@102.5 1/2 21.27@123.5 top out at 154. the 93' rx7 has 255hp-217tq and does 0-60 in 5.1 and 1/4 13.70@102.2 1/2 20.05@127.8 tops out at 172. so there you go the sti has it untill the 1/2mile. Anywase i was just wondering cause my friend has a 93 rx7 w/15lbs.boost and was at the race track and wanted to race an sti that was there but never got a chance to race or see what it ran. but anyway my friend ran a 13.4

:iagree: Sometimes I impress myself.

What did your friend with the RX7 run?

i say the sti all the way to even the 1/2, though the rx7 has a higher top end than the sti the sti would be so far in front at the 1/4 i believe that it would take more than another 1/4 for the rx7 to catch it.
and i always thought the rx7 ran more like 14.1?

well he's got numbers. And I dont know how far in front you are talking. I raced an eclipse gsx, with my gsr hatch, Off the line he got like a full cars lenght in front of me, then I caught up and passed him. It wasnt 1/4mile, it was in the street but it was a lot sooner than 1/4mile

hey Tegdude, post a link of that page you found.

well 13.7 doesnt really sound right for that rx-7, and the mr2 turbo japanese version beats it to 1/4 at 13.8(best motoring source), so it made me think. maybe its the fastest time they got for the 93? maybe the 93 is different lighter version? if not then it deosnt sound right, anyways i usually dont believe stuff like that unless i see it with my own eyes at a drag strip, or if its printed in a well known book or mag. i tend to not go with online stuff, or websites. hope you guys know a lot of stuff online arent always true, more false than books or mags, im not saying all sites are wrong, just that they have more things wrong than other sources.

You're right, thats why I want to see that link, to see where it came from and determine if the info is trustworthy.

How much HP does the jdm MR2 have?

the jdm mr2 was running about 245hp.

when i put it on my favorites i renamed it. but im pretty sure it was www.car-videos.com if that dont work just go to google and type in 93 mazda rx7 1/2 mile. but i like this web page cause it gots both stats! and a shit load of others.

thats a bad ass site!!!

ok.....this is rediculas....bot the rx7 and the sti are on the top of my list for cars.....but the rx7 would most definatly lose at least till the 1/2 mile...and I am not too sure about that rx7 having a top speed of 172....here are a couple of links to settle my case...

http://rx7.voodoobox.net/infofaq/rx7specs.html

http://www.engine-power.com/subaru/impreza_wrx_sti.html

not that its not possible that the rx7 COULD beat the STI in the long run, the only thing that would allow an rx7 to beat the STI is the driver bringing the revs as far up on the tach as possible, every gear, without over driving the motor.....

just to let you know www.car-videos.com doesn't really race the cars, the website calculates it with their own program, so its just an estimate, try gettin the time slips from someone, and also everyone has a different driving style, especially the way they launch, what rpm etc

The RX7's top speed is rated at 155mph. Both the STi and RX7 put up fairly similair performance numbers but (cost being no option) I'd have to go with the STi just for the sound. The RX7's sound so raspy when you really get on it whereas the STi has a nice, deep rumble. I'm in Japan and I was behind a TommyKaira STi on my way home and that thing was shaking my windshield.

Is my RX-7(95, any difference with 93?) that fast?
But I was smoked by a Cobra before... when we both started at the same time...

Your car should be that fast. Was his Cobra brand new? There's a big difference between the 2003 Cobra and the ones previous. Is your car modified? Maybe he got a better launch. A Cobra is tougher to launch but easier to shift because of the broader torque curve inherent in a V8. Rotaries tend to be very picky about shift points because they have a narrower powerband. Have you been able to look at a dyno for an RX7 TT? You need to see exactly what rpm it makes peak horsepower and torque because the space between those points is your "powerband" and is where you need to be. You upshift at your peak horsepower rpm and the next gear should land somewhere around or at least as high of an rpm as your peak torque rpm.

About the first question. Brand New? I wouldn't know, but it looks like those 02(or probably 03)Mustangs...
A dyno? What is that? :uhoh: No one ever told me when shall I shift...I just did it when the engine sounds like it's ok to do so...("Typical female slow-stick-shifting driver", my friends claimed... :crying: ...always smoked by guys that shift fast... :slap: )
All I know is that its a 255hp 1.3 Twin turbo 2-rotary...
but I have no idea when will it happen... :shakehead

Which has more potential...

i mean, if both were modded up to the maxx

Most Street Rx7s that are running good times are around 700whp, Best "streetable" Wrx ive seen was only 450s hp...Ive run against an Sti with 340s at the wheels in the 1/4th and won...but im modded to about 460whp..You dont see many Sti where im from..only about 8 or 9 and most dont race...;) either way id say for street driven use Rx7 has more potential...gettin an sti over 400hp costs alot more and would break more running it hard.

Wow thats just awesome, chosing one car over another for the way it sounds :disappoin
I have a friend that is an rx-7 freak and he told me that rx-7s do have an insane top speed but limited by engine power where as most cars are limited by gear ratios or engine rpm, if you have enough power on an rx7 I believe that 170something is attainable.

Rx-7 only has five gears
most cars with high top speeds have six

18 wheelers have like 12 gears does that mean they go faster?
Ever heard of final drive ratio?

18 wheelers are geared to produce the most lower end torque to pull heavy loads. If you geared them right they can be fast, but thats not what we make them for.

sure an rx7 could have a higher top speed if the gears were set farther apart or the final drive ratio were changed, but it would take it days to reach top speed, a problem which can be solved with an extra gear.

No the RX-7 has a top speed just as fast as a camaro ss with its 5 gears in stock form.
The main reason most v8's have 6 speed is for gas economy and to use a specific power range in the rpm range.

as a guess i would say the rx-7 b/c even though the STi has awd, the 2 turbos and powerful rotory engine would hall balls

The rx-7 is 1000 lbs lighter has a better drag coefficient and an engine that revs higher.

and if six speed trannys are only good for fuel economy in v8s then why do cars like the s2000 and sti which are v4s come with six speeds?

s2000 are I-4 (inline four) and sti are H-4 (flat four) and they are six speed like I said "to use a specific power range in the rpm range."
