Marty's road to ~450WHP

Martijn_b

Car is ready to hit the roads again. Unfortunately all events are cancelled due to covid-19 till June here.

But anyways, in the mean time I fixed the exhaust manifold leak and upgraded the fuel system to the Specialtyz Flexfuel kit. Then my Aeromotive 340lph pump came short and I switched to a Walbro 450.

Did 2 revisions with Seb on different ethanol levels: E40, E60 and E80. We dont have ethanol at the gas station here, so I bought 300 individual 32oz bottles to start with..

Got to say car is a beast on ethanol. The difference in ignition timing is huge and the car feels much much happier running corn. We stopped around 12 psi, I feel on stock block this is about as far as I want to go.

I did 621 engine hp on the dyno (~520 wheel) and expect to be well over 700 now (~600 wheel).

Oh and the exhaust is also finished, the butterfly valves open at 6psi. Love the sound :-)
