My brother and I have been running this car together the last two weekends and I know that its kinda dumb now, but after talking to him last night he has been putting 6.0lbs of air in the hoosiers and goodyears. I feel certian that is not right. I am trying 4.75-5.0 this weekend.
When I have it shifting at 2.200 "7500" it falls back to 6500 if that helps.
Tuning the converter to your car's weight and Engine/tire combination will help immensly.
On the tire thing. Goodyears are sensitive to both air and heat . . at least in my experience. A quarter of pound of air, one way or another has a fair amount of effect. Goodyears also like a little heat in them, somewhere around 110°, 120° if you can get it and keep it while staging.
Hoosiers, on the other hand, will work really well on a specific setting. Once you find the air pressure the tire likes, leave it alone. An acquaintence running an Undercover 4 Link, 560+ BBC has 5.5# of air and it seems to hook up good. Track conditions, or even track temp doesn't seem to have much effect on them. Big Burnouts are actually detrimental to their performance . . We stage with about 90°-95° on a 90° track (average) and they work really well. Personally, I wouldn't use a Goodyear on a tugboat . . but that's just me . . Also, on the Hoosiers, it takes about a half pound of air to make a difference. And you'll know right away, because, like I said, Hoosiers (at least in my experience) are kind of "one setting" Tires . .
