Not sure if this is the right area to post this question as it's more dragstrip related...
When I document my setups for run to run comparisons I always check the tire pressure before and after the run. This tells me that I did a consistant burnout (length, rpm, etc...) I'm just now sorting out this setup on my GLHS (555/520 hybrid 3.50 FD with an OBX running unequal axles and Hoosiers DOT 225-50-15) .
So the first thing I notice is that it pulls to the right when doing the burnout (2nd gear). After the run the tire pressure increases about 1 1/4lb on the driver side and only 3/4lb on the pass side. This is a very consistent difference in tire pressure ratio wise regardless of how good or bad the burnout was.
Not sure if this is the OBX/Quaife normal? Or do I need to stagger the tire pressure to compensate? Or possibly it's the corner weight bias (using some spring spacers in the left/rear but nothing else)?
All of the above??
BTW, now running consistent 12.7's. If I can get less "squat" on launch hhhmmmm.
