After our team raced this past weekend, we took off the manifold to try and chase down an issue with fuel loading up in lower rpm ranges. Upon taking the manifold off, we were surprised to see that the intake runner on cylinder #5 had been severely burned and partially melted. We inspected the cylinder and piston for damage, both appear fine and valves are sealing correctly. It's like that cylinder in particular has way too much advance timing causing a predetonation scenario.
