1st email: Will you ever produce the 94-95 mustang throttle bodies again? Why were they discontinued? their response: We have no plans to re-introduce a bigger throttle body for the '95-'95 Mustangs. We discontinued them when we realized that because of the unique imbedded EGR in those intake manifolds, they made no additional HP regardless of the size of the throttle bodies. It was like increaseing the size of the upper part of an hourglass. Regardless of how big the top part is, the restrction in the middle of the hourglass determines how fast the sand goes through it. Our policy here at Accufab is to not sell anything that does not increase horsepower. It's just our company policy. 2nd email from me: I'm a little confused by what you are saying here. Are you talking about the elbow between the throttle body and intake manifold? There are aftermarket versions up to 75mm. If you are talking about the throttle body itself there are definitely power increases to be had, at least on power adder cars. I have kenne bell cobra and had a 70mm throttle body that gave me idle problems. When i went back to the stock 65mm i saw a 5hp loss at the rear wheels on the dyno. I'm upgrading my blower now and the 65mm is way small. I will be getting a 75mm throttle body from ford racing or edelbrock because they are the only alternatives to bbk. I would love to run an accufab and am 100% positive there is demand for the 94-95's. If your tests were done on stock cars i can see what you're saying, but heads/cam/intake and/or power adders are all over the place on these cars. accufab's 2nd response: Joe, the 94-95 Mustang 5.0's use what is basically a GT-40 or Cobra style intake manifold. The lower part is straight GT-40. The upper part is where the problem lies. The upper part has an imbedded EGR in it, and this is a restriction. If you exchanged the 94-95 upper for a GT-40 type upper from a 87-93 5.0, you would be able to get around this EGR problem because the early versions have a removable and replaceable EGR. In other words, if you want to use a 75MM throttle body, you can also use a 75MM EGR. This is NOT possible with the 94-95 upper intakes, and that is why the airflow does not increase with larger throttle bodies. Trust me on this, adding a larger TB to the 94-95 upper intake will NOT produce more HP. The 5 HP difference you noticed between the 70MM and the 65MM unit was an illusion. Unless you did this TB swap as a back to back swap, on the same day and within an hour of each other, you will get results that are meaningless in reality. A 5 HP difference can be attributed to just a weather change alone. We do alot of dyno work, both on the engine dyno and the chassis dyno, plus, we have an airflow bench. Believe me, if a bigger TB would make a difference on the 94-95 Mustang 5.0's, we would be offering one. If you really want to make a difference, swap the upper intake you have for a GT-40 type upper that fits a 87-93 Mustang 5.0. But be carefull. I have heard that there could be some hood clearance issues. The lower hood on the 94-95 is the cause of all these probvlems, and is why the TB is angled down and forward by 3-degrees. If you have a cowl induction (raised) hood you should have no problems. Same as if you have Energy Suspension engine mounts, becasue they lower the engine slightly. sorry for the long ass post, but i thought it would be good to show the entire string. what the hell are they talking about? i saw a 5 hp gain to the wheels on my car on a dyno when i swapped back to my stocker back to back. i guess i don't even understand what their argument is.
