[QUOTE=Chris "drooze" Wertman;198290].90 racing is as alien to my as my Uncle who is a Martian.
Ok....Here goes....
Ok Super Gas 9.90 index no problem.
WHY do cars use a throttle stop early in the race to slow launch only accel to a higher trap speed ?
Answer: it's easier to see your opponet and judge the finish line if you have more MPH
Why wouldnt the correct approach be to launch as hard as they could consistently , then after the say 1/8 apply the throttle stop based on wheel speed or driveshaft speed to get to the 9.90
Answer: Most super class cars can run one or more seconds under the index and it's difficult to scrub ET in high gear
Instead they launch like my grandmas 77 maverick 6 and then blister along
Answer the more consistent your 60' time is the more consistent and predictable the car will be..
Is this an affect of the electronics allowed ?
Answer: well the electronic do make this possible
It would seem ( from the peanut gallery ) to be more accurate and consistent to launch then depending on launch and depending on performance in air, etc, predict and calculate on the fly the last 1/8 mile ?
Answer: Well if your 60' times vary you SOL and if you were on the stop in the last 1/8 the MPH would be down considerably
and devices that "adjust on the fly" as Steve said are illegal
Im just trying to wrap my head around something I have seen obviously work well, but it would seem contrary to logic for accuracy.
again it comes down to consistency but getting the car on the stop early and shifting into high on the stop have proven to be the most consistent and provide the highest MPH
Personally I wish they would out law throttle stops we could use less motor, less MPH and be side by side like we were 15-20 years ago but I don't think that will ever happen again.
