we went to GLD at the last minute friday night since a couple people I knew were running their cars. It was a flawless night to race, low 50s, no wind, hardly anyone racing either. This was the first time I ran the car with a low DA, and it definitely makes a difference. Unfortunatly their 60' timer was down, so I have no idea what my 60' was for that 14.5 run, I assume a 2.1xx. Track prep was pretty bad as usual. Prob wont be going anytime soon but i'll shoot you a PM next time I go.

 

Boat anchors? The Rays 19"s are very lightweight, even compared to 350z or G35 17" and 18" wheels.....hell, just about any other 17 or 18" wheel for that matter.

The 350z V1 Track wheels are just a tad bit lighter.

^waiting to hear from Dave, but he gave some excellent info. Next time i go, i will consult this thread.

 

BTW, where can i get a revup airbox?

 

from a revup car that took theirs out....or the dealer.

 

Any 05-07 6mt?

 

yup.

 

It's just not the weight I'm talking about. The wider and lower profile high performance tires tend to weigh more than the OEM 215/55R17s, the wider rubber has a lot more drag because of the width, and most importantly, more weight is pushed further away from the hub which isn't a good thing. All that hurts acceleration, especially 0-40mph times. That's the trade-off for superior handling and looks.

 

What was your launch technique?

 

Anywhere in between 1500-2000rpm. I didnt wanna sit there on my brakes for a minute because i dont wanna hurt my car lol so when i did launch a little bit i was more focused on the light. But i remember it being in between 1500-2000rpm.

 

1500-2000? I don't have an auto, but to me that seems WAY too low. I would think you would want to be north of 3k at least.

 

It is too low and he shouldn't be focusing on the lights at all, it's not important. However, the OEM torque converter won't let you stall any higher than about 2,700rpms and that's really not recommended because it takes about 4 seconds to reach that stall speed. You can stall the TC to around 2400rpms with just a 1 second hold, which is far safer and will result in a clean and rapid launch (low 2.2s, high 2.1s on OEM 17s).

 

Your biggest difference in wheels is going to come from the weight. The other points DaveB made are valid as well but weight is the biggest factor.

 

I didnt go any higher because it feels like im abusing my car lol

Ill try though.

Beebo is sellin me his revup box for $20 and my pop charger filter.

 

Braking stalling is a recommended factory procedure to test TC stall speed. It's not going to kill your tranny as long as you don't do it for extended periods (3 seconds or more) or doing it often. Doing it 4 to 5 times every few months at the strip isn't going to kill it. If you drive your car hard, like most us do, then I'd recommend changing out your tranny fluid on a very regular basis (ie drain the 3.1 QTs for the tranny every 15K miles or so).
