I see. I thought he may have the factory performance upgrades. Thats a great trap speed for having that little done.

 

if i shifted into second like that in most cases wheel hop how do i avoid this?

 

Sometimes if the track prep is poor, you can't.

In this case they treated the track, so I hooked better.

If you have the stock rubber, make sure to do a couple of good short burn outs. I found that I get better traction with them this way. After I do do a couple of little burn outs, I do a coupe of quick test launches to see how its hooking. If its sticky enough I get traction with a little wheel hop. Then I pull up to the line and launch.

I always shift right as the rev light comes on at 6,900, going very quickly into the next gear. On a good run it will chirp all the way into 4th, but not spin, just a quick biting screech or chirp.

If that tractions bad, the back end will even step out on the first to second upshift, and has even fishtailed, causing me to let up.

 

I agree, that is how I and everyone I know locally refers to those techniques.

IMO shifting WOT without the clutch is just asking to explode a syncho or something else inside the transmission.

 

If you have wheel hop when you powershift second you are going to need to not powershift 2nd.
I had HUGE wheelspin upon hitting second at the track and found the best way was to do a quick speed shift while rolling back into the throttle in 2nd. Practice will make perfect.

 

The part that puzzles me is how you get a 1.9 60' on a completely stock 350Z (tires and all) yet you only have a 1 wheel drive (no LSD on base model). That explains why you fishtail, but did you even stage both lights? hehe, or did you work out a roll and go deal with the lights or what?!?!

just weird, nice times

 

Contrary to popular belief...on the dragstrip an LSD does NOT give you an advantage over an open diff on normal street cars. I tested this theory with my 97 maxima which came with an open diff. I ran it a bunch of times BEFORE installing a Quaife ATB differential and then a bunch of times AFTER, and saw NO better 60's with the Quaife. Same on the 350z forums...I don't see guys with LSD cars getting better 60's on average than guys with base models. The fact is, in a near equal wheel traction situation (such as a drag strip) the open differential will send EQUAL torque to both wheels just like an LSD.

 

13.84 stage 2 stillen first time at track. Lanched at 900 rpm. No wheel spin and best 60 ft. 2.009. Not a great track but could not leave the line at 2000 to 3000 rpm or it just smoked the stock tires. Its a 2003 5 AT. have slicks for this year and will post in late june. What air preasure did you run?

 

I never thought about it that way. That does make alot of sense.

 

I did not know this, I thought without the LSD, only 1 tire was under power. So why do I see some cars, like some base model rustangs, only peeling out 1 tire during a burnout? Trucks almost always peel out only 1 tire when they try to show off with their weight-less rear ends. hmm (not doubting what you say I promise, just kinda confused now lol)

 

becuase during the burnout..the tires are typically on 2 surfaces with different traction available. Therefore in a differential traction situation an open diff sends the torque to the wheel with the LEAST amout of traction. Once you're staged the surface that the tires are on is very consistant..and both wheels get the typically the same amount of traction.

There is something wrong with your time. Or the blower is not working. See my sig.

Look at his 60ft, its a 2.0, his launch is good for street tires, he should be faster than that. What did your stillen s/c trap Z Eliminator?

 

hey guys.. just curious since I have yet to hit up the track.. for those of you trapping over 100, do you have to shift into 5th gear?? I notice our 4th redlines at about 100..so I was curious.. say you trap 103....can you hit that in 4th? or will you hit the rev limiter??

thanks

 

4th gear will do about 110 on a stock 6MT (dunno exactly I don't ever try to hit the rev limit). So no, stay in 4th.

 

Yeah, I never come close to shifting out of 4th.
