Any advantage with a sheetmetal intake over an LS6/7 or FAST 90mm with an turbo set-up? Or does it just not matter with FI?

there are always advantages with sheet metal.If they are desinged well than they can't be beat...There are no limits to sheet metal.
You can make the runners to flow what ever you want.

I assume with a sheetmetal intake and FI there will be none of that low-end loss of power stuff? Just awesome, even flow throughout the rpm range I guess?????

if its built by the right person . but several cars have run good with a carb style intake. it just depends on what your goals are.

There will always be some compromise with any intake design. Expect to see some lower RPM losses, but that might not be important depending on the application.

Most sheetmetal intakes that fit under stock hoods have some compromising built in, because of space constraints. But they will do as good as the FAST 90 stuff for sure.

I suppose nothing will beat the curved neck type. Like Roofer Daves engine has?

Well maybe I will be more spacific than..In my case I was going to run a car intake but since my allpro heads flow 376cfm It would take ALOT of work to get the intake to flow with the heads..With sheet metal your building the runner to the head and setup..Insted of trying to port it to mach.

Some noted shops prefer the single plane for better distribution across all the cylinders. Feeling with the sheetmetal intakes is that some cylinders, like the back cylinders, could be leaner than the fronts. I doubt most folks would even get to that level of concern though.

lmao..

Like I said before.If the intake is made and designed right than It cant be beat.PERIOD........

Quickin

If less air got to the back cylinders, wouldn't those cylinders run rich????

I think he's saying the back gets more air.

Quickin

Well we know the cylinders always get the same exact amount of fuel, the only thing that can take place is that the back cylinders get LESS air. I don't see how they can possibly get MORE air than the front cylinders.

The theory is that the air rushes in, slams against the back wall, and the velocity of the air forces some extra into the rear 2 ports. Sort of like a ram air effect.

he is correct

mahhddgtp

Yes, and more air in the rear cylinders will lean out the A/F ratio.. That's why those cylinders like to bite the dust, because they're prone to run lean.
