hey guys.......well im new to this board and my car.....i just got it and im 17 years old...well anyways my car wont power**** i get the rpm's all the way up there but it still wont do it.....itll power**** ionto 2nd but not third....any ideas y not?........alos its a 89 iroc-z 305tpi 5spd.....oh and another thign do our cars has govenors or rev limiters?.....i wasnt to sure cuzz i didnt know if they do or not........my car b4 this had both but it was alos newer and not a performance car.....95 z24...lol.....thanx guys

You don't need to powershift, you will rip the T-5 apart....use the clutch....that is what it is there for...yes our rev linitors are at 6250 RPM and because we are 5spds I think the 110 MPH limiter is not on our cars.

Being a bit older (25), I need to ask you a simple question...If GM wanted you to powershift, would they have left out the clutch?

Dude...use the clutch...you will break ANY transmission if you powershift it. Maybe your clutch is going bad or your hydraulics suck. Do some troubleshooting and fix the problem, do beat on it as-is or it will break...something will give.

Also, figure out the HP peak (RPMS) of your engine combo and understand that if you make your peak power at 4700 RPM (as an example), then revving it to 6,000 RPM WONT DO ANYTHING FOR YOU...

These are basic concepts that you need to accept now.

Good luck and hopefully this isn't a major mechanical problem.

are you talking powershifting as in shifting with no clutch pedal like the others are saying, or are you saying that when you try to shift fast (with clutch) you are not hitting third gear good?

Actually, it doesn't really matter, because the definition of powershifting means that he really isn't waiting for the engine and the input shaft of the trans to synchronize and is jamming the gear into place. One can shift a transmission without the clutch, if the RPM's are perfectly aligned to the spinning of the transmission. That is irrelavent though as in most cases, you will grind the gears anyway.

Part of it could be a loose shifter setup (****ty OEM setup) that has seen years of abuse anyway....

Just don't use the words "Powershift" and "Help" in the same post. BTW, the only thing that a Z24 and a Z28 have in common is the "Z" in the name. Don't assume that the two transmissions will react identically. I know this from driving all types of manual trans vehicles, from small cars to pickups to large trucks to semis, etc.

damn, don't bash the kid too hard!! i like to shift my T5 hard, not powershifting but hard enough to spin the tires going into third. When i hit second I leave about 10 feet of rubber. All i do is stab the gas before the clutch is fully engaged. This is bad for it no doubt and i have a broken T5 to prove it (could just be too much power). He can shift his car however he wants, it's his!
Not using the clutch isn't recommended though!!

I think that it is fairly obvious that I am not his MOM....

But look, the problem is, especially as a teenager, that there is a lot of misinformation out there and I am sure he doesn't want to replace his transmission just because he was trying to look cool or make it seem faster...Maybe he doesn't know...it isn't like its implausible here...

For the record, I blew up 2 escort transmissions because I was being stupid, so I know what I am talking about here...



I promise that I am not remotely interested enough to go to this guy's house and measure his clutch depth along with his tire tread to make sure he isn't abusing his car. I really don't care if he is or not, BUT he is asking for some help here.

Good luck and like I said earlier, I hope it isn't mechanical problems.

2...haha...that's nothing....a friend of mine always acts a fool in his car (an auto) and does neutral drops and such....and he has his tranny in the shop 8 times ( dunno how many of those times were rebuilds?). Finally, because he had to keep going back, and had become the places best customer...they gave him a brand new tranny free of charge....then he wrecked the car a week later...isn't it ironic?

thats pretty bad when you blow up 2 transmissions in an escort playing around i completely demolished a 5 speed in a turbo mitsubishi eclipse trying to shift too hard. somehow i got it to stick in third gear, i broke the linkage, tore up 2nd gear and toasted pretty much every seal and bearing in that thing. and that was with using the clutch.

Anybody notice that the his problem is with third gear? I'm sure thats just a coincedence considering third gear is usually the one that goes bad.

I thought power shifting was shifting without letting off the gas. If you pull/push towards the gear you want to shift to with slight pressure on the stick under WOT it will stay in gear. Then when you want to shift you as quickly as possible hit the clutch just enough so it releases. Since you were holding pressure on the stick with your arm, when you hit the clutch you move the stick like a spring unloaded.

Either way it's really bad for the transmission and if you practice shifting(keep racing) the right way you can shift just as fast and won't wreck the trans.

First off, there is a button on the keyboard marked "shift". It will allow you to capitalize at the beginning of a sentence. Oh there I go sounding like an old ....

Anyways, first off I will have to say I am an auto guy but I will pass a little info along. I read an article once about Ronnie Sox (look up Sox and Martin if you don't know who this is). He was one of the best 4-speed guys ever. What he would do when he got in a car is to carefully set the drivers seat until at full travel, the clutch would just release, not go to the floor. If I recall he would not let off the gas but this would allow him to unload the Synchro's enough to shift and he could shift fast enough, even on the 2-3, where you cross over, that he wouldn't blow up those race prepped Hemi's.

If and when the stick lets go you might consider a properly built 700

Those old drag racers would take the synchros out and remove every other tooth, this allowed them to go into gear easier and without much clutch. My dad has a video of old school drag racing, those guys put their whole body weight into the shifts, needless to say, they weren't using the POS T5!

In road racing, you can't make up time by powershifting, you can shift fast while using the clutch and save parts inthe process. If you want to bang gears without the clutch, buy a Jerico like the ones in Winston Cup cars, they're designed for it.
