Hi I have a 89 IROC-Z 350 with a couple mods and no shift kit. im goin to the track this weekend for the first time and was wondering how i should race it- should i just floor it or use the gears 1,2,3?? i want to use the technique that will get me the best possible times!! Thanks for your help!!

 

IF its stock just leave it in drive!

Mine has quit a few mods done and it's messed up the shift points big time. I actually go through all hte gears manually. I get better times that way.

It also adds a little more excitment to hte race knowing your in control of everything!

 

i would say try a run with it shifting itself, try a few shifting it a little later than stock adn see what happens. gm was not very exact in the installation of the shift governors in thirdgens, the later ones got beter, but there is still a fair range over which you will find stock trannies shifting.
the best thing you can do to try to get good et's is to try to stage shallow. it gives teh car a few inches to get rolling before it triggers the beams to start teh clocks.
above all else, have fun!

good luck

later

My car shifted at 5200-5300 on the stock tach basically all stock. I actually got better times shiftung it manually at around 4500 RPM. As I did mods, I found it nesecary to shift it at a higher RPM to achieve my best times. I agree, your best bet it to run it in "D" the first few times then try manually shifting it at different RPMs to achieve your best ET's.

I would usually shift 1-2 a little higher in RPM than the 2-3. It helps the car not to dog when 2nd gear hits. That ratio drop really does suck *** The 3.06 out of the hole rules however...

Tradeoffs...

My last TPI car dropped .25 seconds on average when I shifted 1-2 at 5500 instead of 4800 or 5000, wherever it normally shifts by itself. Goodluck SLP runners will also help you out on this..hehe

I shift myself out of first at 5,500 and then put it in drive and it shfts at 5,500 in to third. Sometimes out of first it will short shift itself.

Let the car shift itself, you have an auto, live with it. Shifting "manually" does absolutely nothing but mess up your tranny. If you floor the car, you should redline every gear anyways. Don't listen to these boneheads that say they get better times by shifting it themselves, thats BS. If anything it makes it worse since your tranny will hesitate before it shifts. Want to

Want to shift manually? Get a manual.

Yeah... i mean if your car needs more RPM to run the number, why bother..

And now I'm a bonehead because my car ran a quicker ET when it was shifted MANUALLY to attain a higher than stock shift rpm...Oh wait no i'm sorry. I'm a bonehead because i shared that information. WHAt the **** was I thinking?

Everyone listen to Justin Flemgold. He obviously has walked the walk and wow his shoes are blazin'.

Don't let ricer boy get to ya, Denny. He obviously came on here to start a flame.

Thats OK though...bring that Integra to Detroit one day, we'll show you how we do it

And FWIW I shift mine manually at the blink of my Harlan ShiftLite at 5500 RPM 1-2 and at 5K 2-3.

No track times to prove it but my g/f's 86 Iroc definately feels faster manually shifting it.

All I know is that I had my Tranny Rebuilt, some real good bells and whistles, When I let the car shift last year, I was running 16.1 and when I shifted manually I got the quickest times when I shifted just before I felt the car fall off. Every car is different! There are variables everywhere and climates and elevations are also varibles. In detroit, at a terrible Raceway (Milan) Shifting at 5200-5400 I was running last year 15.86 consistent. I plan on getting a valve body that is built for manual / Automatic shifting. But the stock valve body is holding up and shifting fine in both manual and automatic shifting. Also do a line lock mod. As long as you only go straight and up through the gears.. 1-2-3-OD. You won't hurt anything, and those of you with manuals complaining that we should get a manual trans, don't be jealous.. Just because we have the choice to manual shift and auto shift that's no reason to be all upset.. Should have choose a different trans if you hate shifting gears sometimes.. Manual trans's are so hard on the drivetrain componets.. 3000-4000 dumps rips everything apart. There is a thing known as backlash and extra slack in the drivetrain, that should be removed before dumping..

Just my 0.02 Yeah there are some disadvantages, but with gear vendors help, everything will work out..

And we should listen to your dumbass because why? Proof's in the pudding - there are several people here that run better ET's manually shifting. It's not a fluke. It would be much appreciated if you stay on your import boards and talk about turbo's & v-tec. Frankly - we're not interested in your BS. I don't go to honda boards starting ****... and I'll leave it at that.

Ahhh such hostility. Just trying to save the guys transmission thats all. And ricer? Haha, thats too bad man, very original. At least my car doesn't live in a shop getting fixed all the time. I would smoke your heavy *** v8 any day of the week. I already beat a brand new Trans AM, with ram air, the works. See you domestic guys think that your v8's are gods. But tell me one thing, how come at the track some of the best times ever are ran by four bangers?

You guys get all hard because your horsepower numbers are so high. It takes more than horsepower numbers to win a race. You have to put that power to the ground my friends. So while you're "wowwing" the crowd with your gigantic burnout, I'll be smoking you up one side and down the other. It's amazing how Honda gets 200 HP out of a 1.8 liter engine (yeah thats stock boys) and your 80's camaro gets around 200 (stock) with a v8. Twice as many cylinders and three times the displacement and I will still burn your ***. Man it's not even funny how off you guys are.

Just so you know, I used to own an 89 IROC Z Camaro, 305. Very nice car, but my GSR would have whooped it while it was stock. Want proof? I raced my friends 84 Camaro with a 305 in it while my gsr was still stock, and I beat him by 3 cars when we shut it down at 90. C'mon man. There's so much more to a car than it's peak horsepower number. You have to lug all that weight around. Take it easy guys, and have fun with your car when it gets back from the shop.

Remember: Transient response and powerband shape is how you go fast, not overly large peak hp and torque numbers.
