Launching the Z ?

kenchan · 11-14-2014, 04:06 PM

problem with the z's throttle lag is that if you idle rev multiple times you tend to miss the perfect engagement window since the throttle latency is so damn big.

that said, its easier to just rev and hold rpm then engage clutch on a MT or release brake from torque converter stall speed.

My thoughts on Launching the 370z:
1) If you want to drag race, you got the wrong car.
2) At the track you will have a rolling start
3) Most Autocross tracks are designed so that the launch isn't important, and start timing about 20 feet in or after the first turn (otherwise AWD would have a huge advantage)
4) On the street, there is no reason for launching your car

That is arguable about drag racing.

Oh I know, and plenty of people to drag the Z. It's just my opinion

Plenty more red light racers than those legally drag racing IMHO

In that case, neutral drops should be fine for them.

1. That depends on what you're racing against
2. True
3. True
4. True, but you can't blame people for wanting to have fun on a closed, back or country road. It's a sports car. People wanna do sporty shyt.

If your at the drag strip . Pull the brake fuse.
makes a big difference.
Just remember to put it back in when before you leave the track.

What does this exactly do?

Pulling the brake light fuse allows you to stomp the brake and rev it in the AT. Otherwise, it'll just cut you off at 13-1500 rpm and eff up your launch.

Thank you for the info about this. I just recently figured out how to launch it without pulling the fuse with my best time of 13.35 quarter mile. What kind of improvements did you see at the drag strip with your times with the fuse out and where is the brake fuse located?

I actually never tried it. Z eliminator is the pro at the 'strip, hopefully he will chime in on that soon. I can imagine it will improve your times noticeably, at the cost of your transmission.

I've never launched it in fear that rear dif bushings would explode. I heard they absolutely suck and they're a bitch to swap.
