The reason I think low 9s won't be trouble is this result from
ET-MPH-HP Calculator If I can improve my 60' from a laughable 2.2, and actually being able to hit 4th without grinding (last time at track my trans was not right), I should be able to get to within .5 ET of theory.
This is what it predicts for 940lb/190hp, I ran 10.7 @ 137 spinning through all of 1st gear on every run.
Your
ET / MPH computed from your vehicle weight of 940 pounds and HP of 190 is
9.93 seconds and MPH of
136.16 MPH.
This is what it predicts for 920lb/260hp, new weight, power level pending verification once re-assembled.
Your
ET / MPH computed from your vehicle weight of 920 pounds and HP of 260 is
8.88 seconds and MPH of
152.25 MPH.
