EFI Intakes..
 

I have been researching EFI intakes for the last few days and I am about to go crosseyed. Other than the TMoss website are there any good website to research a comparison on flow #'s, mild combination power #'s, etc?

From what I am reading right now, there really is no advantage to using any other intake besides a ported cobra intake unless you are turning over 6000 rpm.

I am finding this hard to believe.

That's all I've been able to find ... and it isn't much.

Something's amiss on that graph...Saleen is a Holley...unless they had another earlier one. :shrug:

And the Edelbrock is not that good, unless that's an Edelbrock Victor EFI manifold.

FWIW, I have an article where a NOVI-blown car did 840+ to the tires through a max-ported Cobra Intake. It was a Granatelli car (Red/white/blue coupe said Paxton on the side).

If I were you, I'd get a box-upper for the GT40 lower you have, then you have two intakes in one :nice: ...test them.

It would be interesting to see exactly where the track heat and street heat intakes fall in there as well.

I can tell you that from what I have read so far is that the trickflow 'R' is the only trickflow intake that can compare to the ported cobra and Holley Systemax intake.

As some of you may or may not know, my car is no longer forced inducted. (which throws out any box upper being considered). I was looking at buying a Systemax or trickflow 'R' intake but after doing some reading last night and today, it appears I would be completely throwing away $500 on something that is no better than my stock intake with a little port work.

Note.. Both of the intakes I have mentioned show significant power increases from 6200 or so on over a ported cobra intake but since my combination is going to be between 6000-6200 rpm shift points, I don't I need an aftermarket intake.

Are you staying with the AFR 165's as well? Don't mean to get off topic .. but inquiring minds want to know.

Lee, look at a organization called Professional Products.

:yup:

Go with the Systemax- especially if your gonne be S/c'd

Professional products is just an edlebrock knockoff. Same design, cheaper casting. I think that is the way all of thier stuff is though. Evrything I have seen from them is another company's design, just reproduced.

I've read good things about the BBK SSI intake....

Does anyone know where you could find some flow tests results for intakes?

+1

With a 306 and afr165 the gt40 family intake looks pretty tough to beat up to 5800-6000 rpm, beyond that the flow potential of the other intakes wins out.

Really it just depends on where you want your power at. :wiggle:

Interesting... :nice:

I wonder where the R-series would fall in those tests. :hmm:

Here you go. gt40 vs TFS-R

Test made on a CHP 347 with cnc ported and milled afr 185 heads, XE 292R Comp Cam, and the usual goodies

The results can speak for itself. :popcorn:

Do you need a tune if you get a new upper and lower intake? Or do you only need it tuned if you swap out the cams?

Matt, there are a number of things play a factor in whether you need a tune or not. In most cases though, you will not see much of a gain unless you do a head and cam swap.

Well, Im debating on buying this 91 Bronco with a 302. After doing some research though, it looks like only Edelbrock makes a truck specific manifold. I was hoping I could just throw stang stuff on there, but that would make me lose torque.

Anyone have an idea on a h/c/i pakage that I could throw on it? It's lifted 6" on 35s with 4.56 gears so Im sure it could use a little extra hp.

wonder where my intake falls in there just guessing but somewhere around the gt40? it's a ford motorsports SVO???? wondering i never hear much about these??????

its still a GT-40 intake. Basically what you have is a 94-95 cobra intake. The lowers are the same (flow wise) as the 93 cobra and lightning intakes but the upper is more restricted than the other GT-40 uppers

so ur saying switching to a gt40 upper would be a benefit?

which one? the tubular like a lightning? Probably.

Maybe I am miscommunicating :shrug: Your intake is a GT-40 intake (upper and lower) There are variations of the intake.

All of these are 'considered' a GT-40 type intake

93 Cobra
94-95 Cobra
93-95 Lightning (tublular intake)
V-8 Explorer
Your motorsport svo intake

yes like the lightning or would get the same result from a spacer say 1/2" or 1"? also is there any difference in the saleen intake for the supercharged car? these are pretty rare from what i've seen just curious.......

saleen intake is the Holley Systemax...also the Vortech intake. All the same and VERY good intake for just about everything..especially boost.
