Re: Whipple At 7psi
Like Mike said it would be pushing it on the stock 500efi.I believe the head gaskets are the week link.If ya get a bad batch of fuel.innercooler doesn't get enough water ,ECM program off just a little,not knowing with out dynoing it.etc
I guess it depends on how ya drive it,you probaly can get away with it.
I have been running mine at 7.25 but I changed a lot of stuff in my 500efi to accept the boost,I have gone a lot higher also.but its on edge
Doesent the stock cam only have 11-15 degrees of overlap?
