i have a 91 n/a and i cant leave any kinds of tire marks no matter what gear i am in, or what rpm i dump the clutch. I cant even get a squeal or a chirp!!! is there something wrong with my car? (i.e. clutch, LSD or differentials, what?) Also, i dont know if my car has LSD or differentials. I hear of people chirping their tires in 1st, 2nd and somethimes 3rd. whats wrong with mine??

thanks, eric

old engine = lack of power ....

I can peel out just fine in my '90 N/a... even chirp 2nd sometimes.

But then again, i have a fresh engine

Besides, when you're racing, peeling out is bad

SpeedRacer

All cars have a differential of some sort. The differential on your car is either an open differential or an LSD(limited slip differential) You can spin your tires with either differential although with an LSD its easier to make BOTH rear-wheels spin at the same time. If you are unable to make your tires spin when you dump the clutch in 1st gear(BTW, thats NOT good on your clutch, or tranny at ALL) then my guess is that your clutch is worn out and so its slipping instead of gripping.

My money would be on the clutch, although you can usually feel it slip (kind of a catch and go feeling) I know my clutch is going bad but i can still burn out-try launching at a lower rpm like 3-3.5 and dont do a full out clutch dump do a sort of quick slip. Get your clutch replaced and then i garuntee u can burn out unless somethin major is wrong w/ your engine.

Do the tires not break loose or just not make any noise? On my old NA, the tires were real shitty so it just wouldn't make any noise.

bigfish13515

well it isnt the tires, they have abut 10,000 miles on them, and have a lot of tread left on them. the car only has about 75,xxx miles on it, could a clutch wear out that fast? it might be the engine, i have had some probelms with it recently, but still, even before the problems at 64,xxx miles when it was bought, there was no spin, chirp or sqeaul. does this mean that i am in the market for a clutch soon?

thanks, eric

bigfish13515

oh yea, Ryde _Or_Die, they dont spin at all. the only tme wheel spin is evident is when it is raining, and it is very obvious when that occurs, thanks agian everyone.

the life of clutches depends strickly on the abuse you put it through, if the previous owner dropped the clutch to burn out every day, or didnt even make an attempt to rev match while downshifting, then your clutch can wear out shorter than expected.

Wheelspin in an n/a s5 means you need more or better tire. Or your shocks are weak.
If your wheels are spinning, you're not going anywhere.
Kinda defeats the purpose of the RX7?

(86 na) - i could always peel out and chirp 2nd. in my weenie 165\70\r14 phone dials. they did ok, but they would always break loose when i tried too stay in one spot and there wasnt that much smoke or moise. but today i got some newsed 215/60/14's and boy are they fun. it leaves hella smoke and 2 nice thick lines behind em. its also alot easier to do donuts in them. needless to say i had a goodtime today, i have plenty of pics to take tomorrow. and i can still hit 2nd.

ajsuper7

just open up that exhaust and intake and you spin real good if the clutch is good or not...mine is prety worn out but i got enough power to make some burning tire noise on my michelins. o ya if i have the 4 piston brakes ie hard suspension does that mean i have an LSD on my 91 na s5? or did only the gtus have lsd for s5's?

WTF

Your car doesn't have too many miles so maybe you have alot of carbon build-up. Just a thought.

bigfish13515

i dont think it is carbon build up, i just very recently dorv eit really hard (70-80mph in 3rd for about 10-15min) to see if my car would pass a smog pre test, and it did fine. so it isnt carbon build up. i am wondering now if it is a shot clutch. question:

1) can a stock N/A peel out?

if it can, i am most likely leaning towards clutch, cause to me, it still feels as though there is power, at least people always say "damn this is fast" one time, a girl said "is this a race car? (i redlined a couple times to pass some rice)" i laughed. anyways, it might be the clutch, but a coupel more questions:

2) are there any solid ways to test if the clutch is going out?

3) does anyone in here have any good recommendations for new clutched that arent too much money, that grip really well?

thanks agian everyone!

1) Stock NAs can peel out, my friend did it tonight in second.

2) One test, I dunno how accurate it really is, but it seems to be a very good indicator, is to put it into 5th while you're idling, and let out the clutch. If it does immediately, it's fine. If it dosen't, it's toasted.

3) A 3-puck?

jeff_oner

I have a 91 N/A and I can burn em in first and chirp em in second. no real mods and a weak *** clutch that is going out soon. your clutch is dead or your **** is shot. so either way something is wrong.

Just get an upgraded stock clutch, unless you're modded to hell you shouldn't need much better. I'm willing to bet it's the clutch. If you shift fast from 1st to second does it seem like the car's slowly drops in RPM and then starts to pick up again, or is it a harsh change?

amemiya

I ran 14.9 with just punched out cats and hks intake and acuators tied open. and could rip the **** out of them so come on gives us a break.

bigfish13515

when i am shifting from first to second, i do notice some slowness to it. it is also hard to shift into second from first, where as from second to third and into whatever gears beyond that is a sinch. shifting into first gear MUST be done at 5 mph or less or that dreaded griding noise happens (and it also feels as though i am forcing it into first unless i am at a complete stop). also, when racing and i try to slam it into second (when first gear is at or approaching 8000rpm) i more times than not get a small grind like i am forcing it into gear.

thanks again, and any more reccomendations on brands of clutches is appreciated, i checked out ACT, not bad, but more info from you all.

thanks, eric

just get the ACT S/S, or if that's too expensive, check out the RP upgraded stock clutch at http://www.rx7.com/

if you can't spin 'em but the car seems to have power, chances are it's the clutch
I haven't driven a single 5spd car that couldn't spin the tires, unless the clutch was bad.

try this:
rev to 6k, dump clutch in 2nd gear on dry pavement. if you take off normally, then it's time for a clutch soon.
if the car dies (with your foot on the floor) then time for more power.
if tires spin, everything is OK.

nate

sounds like clutch is gone I gotta agree with you guys, but i also think that the engine might have dirty injectors? i dont really think so but it is a possiblity, + its probly worth it to get them cleaned neway. but try terrh's test, it sounds like it will pinpont your problem better

Does anyone have problems hitting 2nd good with the wheel dimensions I have?-235/45/17...I just broke in my stage 2 spec clutch and seem to be having problems getting 2nd gear to rip loose.

Bumper pool!!!!!yeah.

bigfish13515

i will try that when i have my car back in a couple weeks. thanks Terrh. but a quick question:

when i dump the clutch at 6000rpm in 2nd gear, with a good clutch, are the tires supposed to spin? or take off normally?

thanks, eric
