I ran my G37 at a 1/4 track last weekend and I was a bit surprised at the results.

It took a few passes to get my launch down, I'm not new to racing at a drag strip but I haven't had many passes with a manual transmission car.

My car is bone stock other than tires, I have General Gmax AS03 in stock sizes for the sport staggered rims, rear tires at 25 psi for the day.

My best pass of the day was a 14.94 @ 95.8 mph. I had traction control on to help me keep wheel spin down on the launch, I think I don't have enough tire to properly launch the car hard.

Conditions at the track were not great that day, we were running into about a 50km/h headwind all day and it only warmed up to 15c that day. Altitude at the track is 2400ft.

Should I expect to see more out of it under better conditions? Or is there something else i should be looking at to improve my times?

Thanks!

 

Hit that VDC button. You're affecting your 60' ...other than that. You're within typical 1/4 mile time.

 

Even with your elevation, your 60 foot time is a little slow, at just over 2.4 seconds. As mentioned above, with VDC off and a *little* wheel spin at launch, a 2.2 second time should be easy to achieve with any crappy tire. (I did on my all seasons back in July during a 30 deg C day)

That .2+ seconds multiplies as you go down the quarter mile, resulting is a better time.

For me, I try to launch around 2300 RPM with a rapid (but smooth) clutch release while nailing the gas. More RPM results in CRAZY wheel hop and you can break the rear CVs. This all depends on the conditions of the track.

Key point: 12-15% tire slip is maximum adhesion.
