Are you saying that If you were me, you would go for the better flowing TFS elbow rather than the fox conversion?

Yup. I liked the more gradual throttle opening on the 94/95 setup. The first few days I had my Fox setup, I kept peeling out at stoplights because it was so touchy. For a track car, that wouldn't be an issue. But I like my daily driver to be a little more friendly .

Well Alrighty Then

I'm kinda sorta thinking about seeing if any of the speed shops around my local have a TFS elbow, and if they do............................

I'm gonna take mine over there and compare them

Whoa... that TFS looks much nicer. Like they deliberately made sure to keep a constant radius through the transition.

That's what I should have done instead of going for the Accufab bling bling...

Thanks for the pics.

I've got a good mind to set up a little test of how the two elbows compare under the same conditions by air flow values from data logs.

Troy is in the process of the Fox swap....I'm sure he'll get the skinny on the dif in numbers...I know he's swapping on the same upper as me, 93 Cobra...

I can atest to what Rootus says about the throttle being touchy...That it is, and I like how responsive it is...Its way easy to tromp on it when you dont wanna...takes some getting use to...
I let my Daughter drive mine they other day...That was a trip.... I was like W.T.F.....Was a jerky ride for sure...She just kept laughing and saying what the hell !!!

Thats why i did when i went from the 65mm edel elbow to the 75mm and tfs elbow. I believe i saw almost 20kg/hr peak. And like 4 or 5 on average throught the curve or something.

One thing I will add, when I sent my GT40 to FTI for porting, Ed told me to throw in the Edel. adapter & he would work on it as well. So with that said, maybe the swap did somehow affect my tune. Who the hell knows.

That is all well and good.

The thing I find hard to ignore is that your time/mph returned when you went back to the original parts.

has any one thought of the possible intake volume change between the two?? with the fox parts you are loosing intake volume compared to the sn intake elbow set up .

I thought you guys might like to take a peek at this

http://bbs.hardcore50.com/vbulletin/showthread.php?t=26335&page=1&pp=50&highlight=size+throttle+body

An accufab employee (i guess engineer?) stated that the intake on a 94-95 design is restrictive around the EGR area and thus flows less then a fox setup. I dont know if this still applies when using the adapter elbow, but for cobra intakes i guess it does.

Heres the quote:
A little side note. The upper intakes on the 94-95 Mustangs have the EGR "built-in" to the inlet, right behind the TB flange. We (Accufab) built several different sized TB's to sell to these customers, only to find during the dyno tests that they didn't make any more HP than the stock TB. The reason? We couldn't get any additional air past the EGR area. At least on the 87-93 Mustangs, we could replace the EGR spacer with one that had the same size opening (the hole) as the TB. Can't do that with the 94-95 intakes. The result was that we refused to sell any TB's for the 94-95 year Mustangs. If we can't make more HP, we won't sell the damn things, just our policy. Why take their $250 if it isn't going to improve the HP? That's just going to piss off the market place. Our competitors DO sell a bigger TB for the 94-95 Mustangs. It won't make anymore HP than the stock one but they take the customer's money anyway. We won't.

Its on page two.

Again i dont know that this applies for those using the adapter elbow, but it seems as though it sure does for those using the 94-95 cobra intake (like me )

Yeah i could see that. Since the engineer their stuff to fit on the stock IM then it wouldnt make any power at all with that stock tiny elbow. I think with aftermarket elbows and IMs it will make a difference.
