Default new PB...sooo close to the 9's

I drove the car over an hour to the track yesterday in with hopes for a 9.99 pass.

150 shot

110/93 in fuel tank

116 in dedicated

20 degrees of total timing

11.8-12.0 A/F

275/60/15 M/T radials

1st pass

1.32 60 ft
10.07
131 mph


The car wheelied pretty good and just bumped the limiter on the 1-2 shift which is 7300 ( window switch @ 7100 )

2nd pass NPB

1.34 60ft .. big wheelie and people said I set the front end down after the 60ft marker
10.05
132 mph

bumped limiter on the 1-2 shift again, so it was no fluke

I then got Jim ( our tuner ) to lower the 1-2 shift, put 2 degrees of timing in and added a touch fuel at the dedicated. There was a delay due to a clean up and the sun went down and the track went away.... so I spun and just went home

I had a great day and still very happy with the car. The air was 500-1000 for the day. The converter seems to be a little too loose, so over winter I'm going to make a few small changes to better the current combo.

Pretty cool Larry, but I think a 10.00x is coming before that 9 second run happens. Are you going to wait for a better day and give it one more try this year?

thanks guys

The window switch was only at 4100, so there is still more it it. I feared going on the bumper though without having my limiters on yet.

I think fixing the 1-2 shift and the 2 degrees of timing would have done the trick, but who knows.

this weekend I'm not racing, but if weather works I may try 1 more time

A stiff tail wind would have you in the 9s. Any vids?

about 3400# in full street trim as raced ( 4" catback on and pass seat in place )

We actually had a decent head wind yesterday, so that didn't help at all.

thanks for the props guys

Nice job Larry. Those 60' times are impressive. Hope you get it over the hurdle before winter.

thanks

I am going to go out if the weather works with me the 14th or 15th.

The car will sit the same in full street trim and go for a 9 sec. pass. I know the car has it in it as it sits. The exhaust off and seat out will do it, but it just takes away from working harder at a goal.

I should see better air here too which will help and just need the track to work well again.

I am going to get my limiters on and hope to hook well, keep the front end down. The window switch at ON @ 4100 leaves some ET still on the table.

The video I kept pausing and going frame for frame today and the front tires hit ground just after the 60ft on the 10.05 / 1.34 60ft pass.
