I guess whatever numbers that dyno throws out, whats more important is knowing where the power is being made with the combo and then perhaps some gearing changes may/may not be in order.

As a guide, with an on track 620fwhp/3400lbs the ticket would look something like this>
60 Foot E.T. : 1.43
1/8 Mile E.T. : 6.48
1/8 Mile Trap Speed : 104.88
1/4 Mile E.T. : 10.27
1/4 Mile Trap Speed : 130
with it in the teens? if it 60's better than shown above.
according to my calcs.
