Re: PHOTOS!!! Black RS/Z & the 1/8 mile
I was wondering if I ran some more tire pressure would it cause the tires to spin a little more and not cause it to bog so much when
We let some air out of the tires and the car hooked better, but the ET's went up... could it be that hooking quicker is causing the motor to bog because the car is not moving forward as fast as it was when the tires were spinning more??? (it may sound crazy but thinking about how the car felt and what the RPM's did when it came off the line and the tires caught, this seems possible)

Re: PHOTOS!!! Black RS/Z & the 1/8 mile
You guys should have seen some of the looks and heard the comments from people... like what in the hell are you doing racing a 45k mile original car?
Ummm  maybe because thats what it was built to do...

Better get Rob in on that tire stuff! I like colder plugs at the track. [/ QUOTE ] Do some burnouts and make sure you have all the tire on the ground.. That was Rob's advice to me at Gateway when I ran my car.

Re: PHOTOS!!! Black RS/Z & the 1/8 mile
 And don't be surprised if you go WAY up in pressure. I think Rob is running between 42 and 45 PSI in the Polyglas, and I went to 42 before I got away from the strong edge marks. Even with the 275-14 ProTracs I was up in the high 30s to get an even pattern. May be quite a bit different if you're running drag radials though.

Re: PHOTOS!!! Black RS/Z & the 1/8 mile
I'm surprised they let you race with the drivers side window down?

Re: PHOTOS!!! Black RS/Z & the 1/8 mile
When running slicks i never go above 13psi and never below 9.5. Getting that car out of the hole is everything.To much spin will not go anywhere but all hook will bog the little motor. Also a good idea would be to get the car on a chassis dyno to get the jetting just right. Only trapping 74 in the 1/8th is only showing about 230 hp to the tires.
