My car ran consistent 12.90's @ 105 a month prior to running consistent 12.90's @ 101mph.

No changes were made between runs.

Anywhere I should begin to look?

I don't understand why the mph would drop and not the et.

Car is an '87 IROC 355 TPI.


Do you think that a bad rear end could cause this? I know mine is on its way out.

Any ideas...other possibilities?

Thanx,

It just means that you were quicker off the blocks... I would say this loss can be attributed solely to driver performance... nothing to worry about at all...

Quote from my sister: "It sounds like a boat"

 

quicker off the blocks? I know that didn't happen.

60ft's fell from 1.73's to 1.78's.

That does not equate to a 4mph loss, do you think?

I could see maybe a 1mph loss due to a harder launch but not 4mph...that makes no sense to me.
And being that my 60ft's dropped I know I didn't launch harder.

Thanks for your input, though.
