So I perfected my shifting and can now shift fast enough to try dragracing; one problem, traction is awfull from a start. I have a base model so would getting a LSD help alot? So how should I launch the car on A. city streets B. the drag stip.

atleast tell me how you launch your z car.

~3000RPM was my method(new tires, higher launch, not surewhat itll take yet)

rev the engine to a rpm, let the clutch out fast and smooth, if you lose traction drop that starting RPM. find the highest RPM you can without losing traction.

in your car, its how much power it takes for one of the tires to slip, in LSD you have to break them both.

okay I'll try that today and let you know

Road and track said to rev to 2,000 rpm and just drop the clutch but that doesnt seem to be working

also does it help to let out some air in your back tires, if so how much?

Eric1h

yes, letting air out of the tires helps, it gives you more of a contact patch on the pavemenet, if youre going to the drag strip you can go down to 22-25psi just be sure to fill them back up befofe you drive home for the street, well normal driving i wouldnt go any lower than 28psi

If you want your car to perform at all drop in a nice clutch type LSD. Without it your launch will be hurt quite a bit.

This technique works great for me.

- Get the RPMs up to 3 grand
- Let the clutch out and apply the gas enough to keep the RPMs right at about 3 grand then floor it.

- Lowering the tire pressure and LSD definitely helps!

It is difficult to explain the timing of this -- it just takes practice to get the feel of it, but once you get the feel of it, you'll definitely know it and feel it!!!

I would say that keeping the RPMs right at 3K is the key element of getting a really good launch. It is a matter of feathering the clutch and applying enough gas, but not too much. A little bit of tire spin is good but you don't want too much spin or wheel hop.

It took me a while to get this technique down, but I have so much more confidence in my launches now than when I first got my car. I can hang with AWD cars (if not beat them) off the line with this technique. Don't believe me? Check the vids I posted of me beating a WRX off the line in the Street Racing forum.

Good luck with your launches!

hell yeah sounds like it should work i'll try it; just letting go at 3,000 spins to much; wow you beat a wrx off the line!!!

flyz33

alright this aftenoon I tried 3000, 2500, 2000 rpm's; I let the clutch out fast and smooth; 2000rpm worked the best

Its a slow start for us base owner's; but once we get going we hall azz

any more suggestions?

i have an enthusiast and i have been launching at around 3k or 35 to get a little wheel spin and that nice sound but i found at the track that anywhere from 2k to 25 launches hard with no hop and a tiny chirp. just thought i'd let you know.

After modding the car, dropping the clutch @ 2k rpms results in tire roasting and going nowhere, I have to re-learn

I was told by a close friend of mine that the ratio of 1st and 2nd gear are so close the Z can can launch on 2nd gear with 6K rpm.

i slip the clutch at 3800 rpms and i manage 2.1x 60fts. if thats good enough for you, try it. otherwise i suggest slipping it even higher if you are more skilled than i am (i'm not that great on the launch yet)

i tried launching at 2K.. (VCD off of course)... and drop the clutch.. i'm getting wheel hop almost everytime. Should I let it off slower/smoother or rev higher?

chris_garey

when i drop the clutch at 2k i just let it out as fast as my foot will let me and hit the gas at the same time. if you have vcd then you must have at least a touring and the 18s may have a different effect at that launch. is that on street or drag strip. the different surfaces have a different effect also.
