about 10.2 - 10.6 , depending on tires and other weight factors.

Ethanol content and track elevation/DA will play a small role as well. Could use more rubber out back but I'd bet on a 10.3 assuming the track is sticky and you launch adequately.

You do not list your hp ( what type of tune you are running) Is it soft ? aggressive ? ragged edge ? Will be the deciding factor in your ET and Trap. With those tires, you will likely be running a best case of a 1.6x 60 fr and decent track prep even on a soft tune, so that would put you in the 10.5+ best case scenario as a FBO.

Dynojet ? Mustang ? They all read different and are tuning tools but if dynojet, Iâll throw a random guess at 10.6 @ 133 assuming a 1.6x short. If you have track support or running an advanced traction control strategy and can get the 60 ft launches into the 1.5x range possibly a 10.4.

That's about my guess too, with a DA around 1000 or less...knowledge about drag racing preps being assumed.

Related to this, and I don't know if this has been posted or not, but here's a calculator that is a starting point for wheel HP vs. either 1/4 mile time OR speed: 

 

https://www.calculat...calculator.html

 

Obviously DA and traction will be components too...

 

Example:  My Alpha 9 peaked at 891 WHP...and with Michelin tires would constantly run about 9.7 flat around 148 MPH with my weight in the car as 3950 lbs.

 

Using time (9.70):  855 calculated HP

 

Same car, using speed (148):   999 calculated HP.

 

So, for what it's worth...
