You never posted up how much HP it took.

Was 3400 lb with driver? What was your 60 foot time?


Thanks,

Thanks. That 143 MPH had me going. I still don't think that I have the areo dynamic drag right. If you have the time slip how close is this?


60 Foot ET = 1.2200
330 Foot ET = 3.5988
1/8 Mile ET = 5.6781
1/8 Mile MPH = 117.6483
1000 Foot ET = 7.4905
1/4 Mile ET = 9.0332
1/4 Mile MPH = 146.1391

Stan, be careful trying to back into aero coefficients with data from Cecil County. That track is downhill, Literally, down hill quite a fair amount. Most people run a solid 2 MPH faster there.

And the roll out is huge!

It's less than 1% (13.2') downhill or it would be a factored track...

There are a lot of downhill tracks without factors

Just sayin'
