hey Paul,
Driving the car with 10psi or less in the slicks really affects the way the car handles at the top end from right when you shift 2nd to 3rd..sometimes it can get a little hairy...
i let my friend make a pass in the mustang and he said he had to back off the throttle because he was scared he would lose it..he ran 13.50 at 100mph...
i dont really notice if the spoiler is what is lifting the front, i dont even really notice the front lifting once im out of 1st...right at the start it feels like it wants to lift because of the Cal-tracs bars and the carrera 90-10 front shocks with softer V6 mustang stock springs...and i had to cut 1" off the springs to make the front sit lower...its tuckin pretty close now i dont think i would cut anymore.
I have not looked into adding a front spoiler or making any aerodynamic modifications to the car YET
I think when aerodynamics really make a difference is when your going 10s and slower...so i dont think it would drop a whole second off my time, but the only real way to tell is to try it and compare E.T.s and speeds you never know!
Im pretty satisfied here at 12.498 at 109.79mph...i would still like to run it during the winter on a cold night and advance the timing with the 101 octane fuel to see if i can hit 110mph and break my dad's fastest time of 12.47 at 110.42mph (that was in his 67 firebird 400 ram air in the Superstock class at Irwindale Raceway on 07-08-1967...at that time the Nat'l record in SS/DA was 12.50...so he was doing really well.
He raced a gto earlier in that year at the Pomona Winternationals on Feb. 4, 1967...the fastest he went that day was 13.06 at 108.56mph..
I have a little box full of all his timeslips for the firebird and gto...maybe the next time at the track i can surpass his best.
