That's what I like. Passion in conversations.

Little can I add to this conversation other than these observatioins:

Most really fast and consistent drag cars run autos. I watched a sling of RWD street Corvettes, 5.0's, and a 2010 Camaro ALL run in the low eleven and high ten area most with autos this past weekend. All but one ran an auto.

The built auto spreads out the power spike so it doesn't break axles as much, and it doesn't lose traction as readily. Plus they are easier to drive.

(This was the motivating factor in my decision to get away from my 10 second STI (street tires/AWD but with stronger axles). I sucked. 50% of my runs had some shifting or traction malady. No, make that 75%.

)

I'm not convinced you NEED axles to get into the tens, but it's good insurance. At present I'm simply trying to get into the mid elevens, and with 1.8 60" times, I am hardly at the breaking point of the driveline.

That traction control and it's suitability on the drag strip is all conjecture until someone actually posts a time card. To that end, If it DID work up to it's claim, it would maximize the available traction, but having slicks (even DR slicks like I have) would up that threshold.

Now that GTM is making a kit for the G37x, well then: Imagine a G37x Coupe with 18" DR's all around on AWD and a semi-built auto. That's the 10-sec chassis combo for this engine.

Ooopps, I'm in the 370Z forum. Sorry.

I grew up ONLY of drag racing, so I love this topic.

(To those who love that loud GTM vid of the sweeet 370z. That is exactly why I plumbed all my returns to recirculate. It's loud.)
