So on the 20th I'm heading to the track for my first time in a RWD car. I learned to drive on an awd subaru wrx, and launching it is much different than launching my 350z. All my drag racing time was done with AWD

So, I'm curious about the techniques most of you use here. I have tried launching like my wrx, feathering the clutch, it doesnt seem to work too well though. The car doesn't plant like I think it should.

 

3.5k and feather off the clutch while adding pressure to the accelerator at a swift pace.

 

what does feathering mean?

 

Well, i can tell you how NOT to launch it..



That was the end result of a 6500 rpm launch off the Fcon Launch control..
N/A I would reccomend reving to 3000rpms and riding the clutch out till it hooks. Problem is, the clutch will heat up and wear out faster that way.

 

Practice-thats the best teacher

 

What was done to the car when you did that - and what cause the oil pump to....fail? or whatever?

I launch at 5000 RPM's, but it wasn't easy learning how to control the clutch and not spin/overheat it.

Start lower, I have to every week until I get a feel for the track.

 

MRC's car isnt exactly stock. With that much power a lot of stuff can break. It was also an older oil pump, that was not replaced in his build and probably shouldve. (He spoke of it in the Forced Induction forum)

To the OP, I would also say to just practice. Its obviously not going to hook like your WRX did, but if you can slip it out at 3.5k and up, you can get a pretty good launch. Just dont dump the clutch. Lift it up a little, just before it really engages, raise the rpm, slip the clutch, and nail the gas. Its hard to do on the street well, but if the track is prepped properly it will make for a good launch.

 

thanks for all the info, i've been practicing but the #'s will show it at the track, i'll post back my #'s....

my goal is a 60ft under 2.5s which I think is easily achievable.

 

depends. I ran my car on an unprepped track and all i got was 2.6 on my 60ft on all 3 runs.

 

I'm in first to 40 MPH, thats all of the 60' and most of the 330' (time wise) - the difference is incredible....I think I'll stick with having a first gear launch myself.

 

Peak350 take a trip to Moroso on friday for the 6pm - 1am Midnight Madness lol, I'd love to have you there to show me some stuff. J/K...Unless you would actually come . I'll pay for you to get in and buy you a beer.

 

Friday is my mom's birthday, and saturday is one of my best friend's 21st, so that has me home all weekend.

Maybe I'll make it down at some point, my GF is from WPB, and I have a few friends down there. But more than likely I'll just keep running in Gainesville until I get 12's (bolt on if need be) and maybe a trip to valdosta or bradenton.

 

If you cant better a 2.5 60', then you need to find a new track, or find a different hobby!

 

If I dont do better than a 2.5 60' you may have my car. I'll post the slips tomorrow night.

 

2.5's are horrible, even a nub like me pulled 2.3's lol.

 

Well this will be my first time to the track in a Z lol.

I could land a 1.9 60ft on a bad launch in my wrx.... I really don't know how my Z is going to react to my style of driving when I get to the track... so I'm going to need a lot of practice with the new car.

Practice!!!!!

 

Launch it liked you launched your WRX just at a lower RPM around 3k like they were saying (feathering the clutch). Unless that is of course you didn't drop the clutch in your WRX. I came from a Subaru also... 2.5 RS with consistent 1.90X 60's
