Well just got back from the dyno today and a short trip to the track, My Heffner Supercharged Snake was pretty respectable,570 rwhp and 580 rwtq on Heffners new dyno.That is was with the factory exhaust maninfolds, converters and exhaust no other mods but my 6 psi vortech supercharger and ammoco 93 octane pump gas.
Took a short trip to the track,haven't been since englishtown, after a couple of passes in my aluminum 65 shelby 427s/c which were pretty good 10.67 and a 10.71 at 128mph on bf goodrich ta radials.I thought I would try to beat those runs in my viper, after a couple 11.00's on my 19" pzero's I was able to break into the 10's with an 10.85 at 131 but could not beat the cobra so after bolting on a pair of drag radials and a couple of runs in the high 10.7's I was able to break off a 10.51 at 133 finally besting the cobra.Not bad For Heffner's Level 1, but I thinking Level 2 and some 9 second time slips.
