It is actually more of a weight issue than it is a power issue. Q16 with an intercooler and M5 with no intercooler have made almost identical power on the same motor. Pappas runs good with a single and alcohol and Millen runs good with a single on gas. Jensen is running strong with a single on a big inch sbc with alcohol. It all comes down to what the organization you run with allows and your own personal preference.
