ok
My car has run a best of 6.82 at 98 mph in the eighth.
I have got to wonder how there can be such a variance in the pressures run, on these tires and they still work.I had no luck at all getting any kind of launch.
when i normally stage with the wrinklewalls( old tires),i can get 3000-3300 stall easy ,now with these w's ,all i can get is about 2500.
the one time i tried to "get it up " to 3000,the car creaped through the lights,and the fronts pushed ,the car did not pickup the front end,and it fell off by 4 hundredths.
this car sixty foots(with old tires)between 1.43-1.47 pretty consistantly,but with these m/T's the best sixty foot is 1.49,and i am leaving 500rpm too low.
wierd stuff?
I cant go test at the HOT ROD reunion so that is off....going to test at clarksville wed nite instead.
i think i am gonna end up buying a new set of hoosiers and take my beating on these M/T,s,they just dont want to work.
i never thought it would make this much difference.
Here is my combo:
67 Barracuda,
440
ported 906's
12.0-1 compression,
edelbrock performer rpm,
demon 750'
727...manual valve body,
4.56 dana with superstock springs and a snubber,
3280 lbs with me in it raceweight,
best ET> to date 6.82 @ 98.05 mph
over 1500 passes and counting....
Now i am stumped on air pressure,never had a set of slicks that wouldnt work.????
