Ive just managed to dig out the old fastford magazine that featured the white SVM car. The timing slip printed shows....

Reaction... 3.150
1/8 ET... 7.545
1/8 MPH...87.02
1/4 ET... 11.994
1/4 MPH...110.89

He used some sort of Armtech launch control and ran 10psi in the front tyres.

From the magazine..
"The times dropped to a 13.6second run in August,followed by another 13.6 the next week at York Raceway...But later the same day Nathan posted a time of 11.994 seconds."

Who knows, but thats a HUGE drop in time in one day
