Tuning and ET ?

Okay , I know I ask some random questions that have a lot of variations , but here goes?

On a 1/8 mile car with new engine and say a safe base tune , and runs mid 6s off the trailer.

What average ET should a person expect to gain with a vehicle running mid 6s when tuned to potential?

In other words the base timing is set low , carb jetting is unknown ,  launch rpm is is 1000 rpm off of converter stall speed , shift points are 800 to 1000 lower than cam specs recommended.

This is a grudge race car and so I am trying not to give to much info away.

Thanks

With that kind of "conservativeness"....there is still a bunch of power left in it. If he's going mid 6's....say 6.50's - .40's...which equates to about a 10.00 flat to a 10.10 in the 1/4, I'd think that picking up close to 3/10th's is not out of the question when the tuning brings everything up to "full spec".

Depends a lot on that base tune and sweet spot of shift point and launch rpm. Mine is very forgiving on launch rpm. But it will lose almost 3 tenths on a 300 rpm drop on shift point because it gets out of converters range. Just hard to tell untill you turn it up and see what is in there

3/10ths is about all we are looking for ! but we will take all we can get !

In the eighth mile ... 3 tenths is not much when you start at 8.50 seconds but, if you begin at 5.00 flat it is a whole lot.
