I need to get it below 135 so that I don't need a license to drive it. Can you scrub off 8 MPH using the throttle stop?

I had to kill about .7 or .8 and did it all in the first 2 seconds of the run. Only lost 1 or 2 MPH. You'll have to do it in the middle of the track. If you get too far down track, you won't be able to get the ET into the 10s. Consistency goes away when you run the stop too far down track also. I would recommend a 4 stage timer (drop it once early to kill ET, drop it again at 1000' to kill MPH. Makes it tough to fender race you too) OR some type of stop or bolt on the carb/throttle linkage. If the results don't match the theory, change the theory.

They slid in a new disclaimer at the front of Super Pro (section 4 A) of the 2009 rule book which is on Page 58 and it states " Any vehicle except ET motorcycle running faster than 135 MPH must meet the minimum requirement for 9.99 second vehicles "including driver credentials and protective clothing" That last part is the new addition. So that means that all of you Super Street guys that run at 10.90 and 145 MPH, but don't have a license will need one now.

T/S will kill et not alot of MPH 135 MPH will be interesting with the street nitrous cars and s/s car.

We run 1/8 mile and one Camaro capable of running 5.70's, throttles stops it off the line then again at the top end to run 6.30's at 110mph. So it is possible, depends on how you set the stop. My 1.298 60 ft 6.001 1/8 mile 114 mph 9.52 1/4 mile 140.87 mph @ 3110 lbs

However having played with my very consistent daytona, throttle stopping it on the top was a little less consistent. Because your going at a high rate of speed, and then slowing it down any amounts of wind really effected it differently. If not too much work, may be a better route to regear, or recam the thing. Taking some cam out of it, wont hurt consistency and will help everything live much longer. Just a thought.
