street tires at the track - any tips?

A tip not many people know.Find out if your track has a concrete,or pavement launchpad.Fine out,then,find a similar spot.THEN,LAY WATER DOWN.Launch the car ,as if yoh would on the track.If this is truly a new combo,this will show with tire speed(slowly), how the car will work with the new mill.Sounds far fetched,but it works.....
Nothing like a little out of the way street testing, i did it constantly. Even had a special 2 mile loop from my house and back that included a interstate on ramp that was straight and about a quarter mile long. Adjust timing, run the loop. Play with jetting, run the loop. Was a Sunday morning ritual for me.....lol. That was in the 70s and with traffic and development now days i'd never get away with it.:D
