ford and holden both have to keep each-other in check with stock power figures, also the supercar scare shit will return if they go nuts.
Ls9 has displacement and that is all and with 1.2L still isn't as efficient uses more fuel and needs more mods to be on par with a 5.0 on same boost levels.
power handling potential? on stock blower 5.0 coyote many people have made 480-510rwkw stock engine zorst pulley intercooler tune e85 intake.
ls9 will need heads cam, zorst intake pulleys e85 larger heat ex-changer(internal plenum cooler and external radiator)
keep in mind here the 5.0 coyote has a 1.9l blower and the ls9 has a 2.3l
imo stupid debate anyway, FKN v8 MATE
