sorry just saw this post and hopefully this will give an idea on potential in a small tire heavy car application…. We are still working out the bugs on my 610 Predator but are very please with the progress… We were at 3150lbs on 275s in Memphis last month and went 1.101 sixty 4.566 @155.90 mph… we had hurt the motor GA and only had time to patch up so put head gaskets and was a little down on compression on 2 cyl so we pulled the plug after 1st qual… My engine made 1210 on a tight dyno and I know that is only a number… we are spraying a hefty dose but only one kit..can't wait to get back out
