ET isn't what to look for. MPH tells you what it is making. Using the weight of the car and that MPH number will give you a decent "chassis dyno" number right there.



The mph falls off considerably when the car wallows around for the first 300 feet.
I think it's a good idea to dyno an unknown car before taking it to the track. You can get an idea of how the car is running before blasting down the strip.

Dyno can take an hour or so. It takes me longer than that just to get to the track. The dyno is cheaper in most cases.
I like getting an accurate air/fuel ratio too.

In the OP's case, the 13.5:1 ratio is a little lean for WOT. It will make slightly more power at that level but it's MUCH safer to get the mix down to 12.5:1.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
