Inlet Manifolds - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Does anybody know of any comparisons made of the available aftermarket inlet manifolds for 302W blocks? Specifically, I would like to see the results of a proper test on a flowbench or something. Comparing manifold runner lengths and flow rates would be interesting. There are heaps of such comparisons for cylinder heads, but what about the device that "feeds" the heads?

The manifolds I am interested in (at this stage) include the TFS Street Heat, TFS Track Heat and Edelbrock Performer. Are there any other readily available ones that I should check (eg Holley SystemMax)?

If I cannot find a good comparison of these units, can anybody tell me the runner lengths of the Edelbrock Performer and Performer RPM manifolds? I have no interest in the RPM for street use, but knowing the differences in runner lengths would be interesting, especially as the RPM is supposedly a dog for street use. Details of the TFS manifolds are available on their website.

Note that target donk is a streetable 347 stroker (idle - 6000 RPM range).

I love your work Big Mick. Clearly, I need to refine my Google skills - I couldn't find any articles like this less than 8 years old. Thanks!

PS Why are you selling all those Windsor goodies? I hope everything is OK.

Damm, they are some champion articles!!! Why can't an Australian mag do the same thing, maybe a letter to "Performance Ford" is on the cards.

Ah yes I remember reading that anderson article a few years back! Great article and always good to see them giving such a thorough set of results. Still happy with my GT40 upper - especially for the price I paid!

Those inlets are nearly as old as the hills, around in 93 Cobra etc..Plenty new inlets out much newer than them.

Which inlets?

Did you read the info at all three links or just the first one?

Got it mate..Sorry..
I wander if the suposidly higher flowing inlets would be better up top with ported tfs heads?? Pluss I guess strockers help too..
Its a shame the Holley won't fit correctly on our engines...
Amazing how they vary at different rpm's esp Gt40-Cobra- Explorer...

Hi all, Spoke to Terry Parker (of funnel web manifolds fame,) he tells me that his mate Richard Holdener (excuse the surname) is a very well known writer for all the major mustang mags in the states, I've also got a few of his earlier books, anyway he recommends the latest offering in the performer RPM range - RPM series 2, seems to be the one cleaning up in all the U.S. dyno tests, haven't located here yet but looking into it this weekend

Yeah it does produce good power but loosed a lot of down low torque. Fordmuscle put one on their project street buildup and went straight back to the standard performer becasue the low down loss was too great for a street setup. It would be perfect on a 347 stroker I would think.
