Quick comments vs. my old combination that ran 11.0s usually and squeeked into the 10.9s - 60s were 1.51-1.53 - 1/8 ETs were 6.9s-7.0s - 1/8 MPHs were 98+ - 1/4 ETs were 10.9s-11.0s - 1/4 MPHs were 121-122
If you're looking for 6.9s/10.9s, in addition to the obvious 60-ft improvement required, I think you need to figure out why your 1/4 MPH is dropping off 2-3 MPH compared to mine since the 1/8 MPHs are comparable.
