That track is really wide, sure looks different than what we're used to.

Sounds like you're almost into the Super Pro category!

Roll out of the water more. The splash of water when you start the burnout slings water all over in the wheel wells as well. With that much water, roll through it. Don't even hit the throttle to spin the tires they are wet enough. Stop about a foot beyond where the puddle ends. Do the burnout there. Now you are relying ONLY on the coating of water on the tire to get it spinning and there is no giant splash. Then you will find you are getting the tire hot instead of trying to boil off all the water on the ground.

If you roll through the water towards the starting line and stop when you just pass the water puddle, the burnout will be more effective. In this video, at the beginning you can see the water puddle BEHIND the car and the burnout is done on dry ground.

And with your ET, you clearly have the HP. My car at 9.32 had a 60' of 1.28. At 9.67 it 60' at 1.35.

Hope this helps.

My car was never as heavy as yours. Only 3400 was the heaviest it was on small tires. But it did go 1.42 in 60' and only 10.38. So I think even with the tire you have you should be able to improve your 60'. I wouldn't get excited if you don't get down to the 1.20's but I would think a 1.35 is doable.
