I asked him about a 6.1 system and he said he was in the process of putting one together for a customer but was going to limit the boost levels to 5 psi or so because of the 6.1's higher compression.
All in all I was very impressed by his (Jims) knowledge of the 5.7 / 6.1 engine.
He mentioned that the 5.7 intake has some kind of restriction (he went into detail but I forgot the specifics) in it that could really hamper the ability of fuel (or nitrous) to distribute evenly throughout the intake, thus making the larger injectors (or direct port for nitrous) the way to go.
He said the 6.1 intake does not have the same restriction. |
Hey, Igotta. I have tried to contact ASM via email regarding their fuel system. I have a 6.1 and want to know if their ECU is suitable for the 6.1 and if it can be bought seperately? I have not heard back from them and i have tried a couple of times. I have a competitors S/C fitted but would dearly love the ability to utilise the port injectors for additional fuel rather than the external ones. Maybe you could make some enquiries if you know them.
