Turbo Marauder 4.6l IC

[juno]

Thanks Richard!
I do not suffer from knock at all right now. I will not be flowing the 60's anywhere near 100 %. I will be sticking to about 430-450 rwhp for the street and maybe 480-500 for a track tune.
My concern is that it is frigging hot down here (90f +) for 9 months out of the year.
I do not want to lose performance to the heat.
I do not want any chance of a knock.
I do not want to lose the motor cause I got a crap tank of gas.

In the future I may want to go for some big numbers.

A few bucks for an injection system would be cheap insurance for my motor if it is practical. I would prefer something that kicked in at 1 psi if possible.
