5sfe intake manifold problems Options

[Kerr1]

Ok...every1 talks abt how the 5s intake manifold and head do not flow very well...wat exactly causes the manifold not to flow well...the reason i am asking is b/c i was thinking abt. a custom manifold MAYBE...lol...and i was wondering if ne1 had ne ideas on wat would b the best setup?

The 5SFE was designed to flow most efficiently at lower RPMs.

I don't know as far as the manifold goes, but the valves in the head are angled so the air rushing into the cylinder mixes well at lower RPMs, but as a result of this they don't flow as well at higher RPMs.

and that's why a 3sgte head works wonders

obstructions.

My manifold flows rather well. Besides, you dont want to roll at high RPMs all the time, that's just wasting gas. it's just the way that our power curves. Us A/T guys have it way worse anyway. We've only got 4 gears... 3 gears if were not driving in over-drive mode.

And my celi still has no problem getting up and going somewhere
