Anyone know what will fit under a stock hood? I don't want to rev it much over 6000 rpm. I am looking at a RPM2 or trick flow.
Have you done it? I have.....

How do you know?
clement said:I have done what you are doing.
clement said:boost will elevate the airspeed, which will cause the powerband to shift lower.
What effect will runner length have on rpm range?
clement said:runner length doesn't effect peak hp rpm, runner length effects how far it holds on after peak.
An 18" runner or longer would be more inline with what's being asked of the engine. However, now we have several conflicting goals. Do you want something that fits under the hood, something that makes power, or something with a slab of off-idle torque? "Decent" economy with E85 going a through a boosted engine built for pump gas just isn't going to happen IMO.
I mean, the impression I'm getting is that even a stock Lightning intake would be suitable.
Airspeed where?
Long runners are more conducive to making torque at lower RPMs. Ideally port tuned length would be chosen in order to bolster a desired area of the curve while sacrificing a less important part.
That's going to depend at least partly on the target harmonics...
ok, I thought we were talking about a less serious combo.
