5.0 EFI intake ???????

[JimmyJack]

Have you guys ever seen an intake like this? Any pros cons????

They sell them at Summit Racing. I thought about that to clear my hydroboost. Someone said it looses low end torque. I don't know if that's true.

Re: 5.0 EFI intake ???????

I would think that tank is designed for very high speed...more like the old days tunnel ram (short runners). It is my understanding that the longer the individual flow port (runner length), the lower the torque. The runner acts like a spring, the timing of the intake valve opening and closing vs runner length sets up a natural frequency in the air column and when the intake opens again, its like a momentary super charger effect dumping more air into the cylinder. So when the runners are longer (like in the Explorer intake) the torque comes on at a lower valve opening frequency (lower RPM). Anybody else chime in here?

Interesting I agree, longer runners=more torque. Comp's claims are an increase in HP and no drop in torque.
May have to do some weekend dyno testing.

I think those are more for racing and high RPM applications.

It says that you gain HP and 300 RPMS

Yup right on, then theres the scavenging in long tube headers

Wow, that's really cool, I'd give it a try!
I don't understand how your gain 300 RPM though, What over rev's a 5.0 is crappy valve spring lay out.
For 300$ I'd buy it just for the ability to remove both valve covers.

Re: 5.0 EFI intake ???????

Well I bought a harness and extra computer for $200 from a guy on CL and he threw it in. I may try it and see what happens. I am geared so low that I'm not sure that I'd feel any loss in torque.

post up some pics of what the internals look like before you install it. I would be curious if they tried to wrap the air coumn or tried some other tricks to keep the effective runners as long as possible.
As for the write up: "gain 300 RPM"...sounds like the classic marketing verbage for stupid car guys - makes no sense. I think it shifts the HP curve so it peaks 300 rpm higher which would mean the torque curve may be the same at 300 rpm higher too. that means you loose low end torque..but technically if the curve shifts ..then you haven't "lost" torque.

Re: 5.0 EFI intake ???????

When I build my 408, I'm trying to decide if the Trickflow upper and lower will be neccesary or if the BC adapter for the 5.0L plenum will suffice. I think that type of an intake for a 5.0L will be too much but for a bigger engine... I'm not sure...

Re: 5.0 EFI intake ???????

If your able to remove the valve covers an not remove the intake,, that's a win.. And no hydroboost issues.. Try it.

Fit under a Bronco hood though? dunno, give it a shot

I bet it will..
