How does this plug look? 4.6 DOHC 3.4 whipple crusher at 25 psi. Afr is set at and running at .71 lamda 10.5 gas scale. Timing set at 18 seeing 15 due to high IAT. Plug is BR7EF. Should I go to an 8?
Gonna give the lower intake meth injection install a shot.
With a 2.3 whipple at 19psi and a 625ml jet from Snow in one of the vacuum ports pre blower we didn't see any decrease in IAT2.
I am using a snow kit and CM5 cooling mist jets (lower profile). Going with 4 jets one for 2 cylinders...
