So yes, there could be significant ET reductions with this part.

Jeff, you say maybe not, then you say its possible, and then you say significant. I do think you have any real knowledge if it does or does not help performance, I do.

My car weighs 3200 pounds and runs 9.80's, that is very light for my class AA, most are 3400 plus. If anyone is going to have an issue with spinning the tires it will be me. I have tested and there is no advantage what so ever. Oh yes, the difference in weight was 11 pounds for me. I would like to see data on how much performance is gained by moving 11 pounds in cars that weigh 3400 plus.

When I asked NHRA if it was a performance advantage, they told me it was not. So if NHRA does not think it is a performance advantage, this argument is mute.

Bob, maybe you should be the one not hitting enter.
