In tests one guy has run 7.40's and 7.30's consistently at about 188 to 190 mph. They gave feedback of these new seals withstanding blowby at high boost pressure above 35 psi with methanol. They would have to teardown due to blow by. With the new seals they dont encounter the problem any more. He said "the factory ones lasted shorter than an earth quake"RotaryArt O ring kits
