SO what im looking at is... theres 55 people so far who don't even know how fast their z is yet ? =D>

In my opinion hitting the rev limiter is ok but of course repeatedly doing that does in my opinion stress the chain as the sprockets are slowing and accelerating the chain back and forth. Also not all engines have a rev limiter because the engine will not spin that high and explode. More so due to the fact that they are cammed for lower rpm and efficiency and mileage so the powerband is pretty much over so they just set the limiter where it needs to be. There are a lot of motors that can safely rev a LOT higher than a factory limiter like some of the jap cars (2jz etc) with no ill effects. They just crank the boost and up the rpm on a stock motor and away they go.

Tom,
I don't really launch the car all that often either but when I do I leave at 2.5k and just hammer the **** out of her. I look at it this way, I have street tires on the car and if anything is going to break on the car, they will go first. But I hit 7000 in third quite regularly

Hi Kevin & gingle bells! Thanks for the tip, 2.5 seems to be the # everyone uses. Yea you are right about the tires..I forget that they are not gonna hook up to cause a failure in the IRS. I guess I'm too conservative in my thinking. Chicken me I am.

Let me ask, a combination of speed of coming up with the clutch pedel and going down on the gas, right? Object is to not bogg it and keep a reasonable degree of traction, so it's a balancing act between the two. I'm thinking care is a must or the clutch disc will over heat?? I've just recently started to try a little of that in brisk accleration from traffic lights. I was doing what the owner's manual said about " you can come off the clutch slowly and your corvette will move along without giving it gas except on steep grades". I know it must seem funny to all the other Z owners but it's been 20 yrs inbetween vettes. Coming from 150 or less hp for the past 20 yrs makes you forget what a real motor can do for you, let alone the TQ an LT5 has. To me it is a marvel the smooth power it has!

Thank you for your insight!

Tom

Tom,
What I do is I hold the RPMs at 2.5 and bring the clutch back toward me as fast as I can without sidesteping it and I mash the go peddle as hard as I can

tomtom72 · 12-27-2005

Oh! & Duh! Thanks for the "how to" on the technique, Kevin! That sounds reasonable, and not very abusive to the drive train. It's been along time for me between vettes, and a car that has some hp for that matter.

Hey, I have had my ZR-1 for a whole year now! Yea!
Man, these cars can cure a bad day!

I was doing the ~5,000 rpm launch described on CF at Englishtown. That seemed to work well. The idea was to hold ~5,000 rpm and launch the car with the clutch. I was probably seeing more likt 4-4.5k, but you just let the clutch out as the tires can handle it and off you go. Of course my 2.2 and greater 60' times might not lend credibility to this, but with 10 year old GS-C's putting it down, I thought it worked ok. Seemed to work better than lower rpm launches that either broke it way loose or bogged down (which seems worse for the clutch).

Tom, so your shift light actually comes on? Mine doesn't seem to and I thought later GM ECM calibrations didn't turn it on anymore. But maybe I just have a bulb burned out...

Still a Z noob here, but it seems with a Dana44 and spicer Ujoints there shouldn't be any breakage issues.

This techinque will work quite well....I just don't like having to replace the clutch all the time.

I know with my aftermarket chip I lost the upshift light which made me sad I'd like to find a way to get it put back in.

Thanks guys, Kevin, Bob & CAV!

Humm, I never thought about a chip turning off the shift light Bob. The chip I bought is just the replacement update for the OEM 1990 chip. Yes the shift light does work. I guess your bulb could be out? Maybe you have an aftermarket chip? Also thank you for sharing what you did at Englishtown. I hear ya about the GSC's, mine were old & hard & I replaced them with D3's.

I guess I worry too much about the IRS, too many parts & no place to work. The stuff sure looks nice though! I hate to say this but I'm still partial to the detroit locker in my Mach1, that would do the trick in the launch department!

Once the clutch is engaged & the speedo says something I have no quams about lett'in her rip, it's fun! I guess I'll never be a drag racer!

Thanks for sharing Guys!

Tom
