Well I went to the track tonite. One of the LM guys dragged four used Hoosiers W30's along for me so I can get some rubber on the old girl that hold's air.
I spent about three hours asking questions and generally being a big PITA. But I learned a bunch. I now know the concern about the right frame rail is valid even if I don't set up the car exactly the way most modern cars are run. The driver who brought the tires runs an '08 Rocket so I took a lot of mental notes. I talked chassis with him and engines with his Dad who builds 'em for the team. Despite the rather liberal rules allowing several different combos most guys are running Brodix spec heads, 360 ci and around 650 HP. A couple open engines with restrictor plates… no crates or IMCA engines in sight AFAIK.
They broke a piston a few weeks ago in the 'good' engine so they put in their spare bullet and they were down 50 HP. Tough nite… handled good in the heat but no forward drive in the main. RR tire got a hole in the heat. New RR didn't seem to help.
Still doing homework. Looks like the cutting wheel and plasma torch will get a workout this fall.
I could run leafs and I would be comfortable fab'ing the brackets but I'm not sure I could get the corner speeds these newer car are getting especially in a big 1/2 mile like Shawano. My super is a leaf car and every car I've raced over the years was leaf except my IMCA mod. But it's been years ago...
I will say that these cars fly when you are watching from the pit wall… certainly more exciting than in the grandstand.
