and by the way Al, that was a hell of a find, great experimentation!!!
you will not get more airflow using an oversized TB, your connected to a 65mm plenum, think about it.4.0L Sleeper said:its the SOHC, I need to give it more air because I am about to get the heads done and a cam as well, thank you very much for your input
Do a search under ported tb mod,I have a pic posted showing the differance.4.0L Sleeper said:I didn't know if i could port the stock one because its plastic and the fact that it would be extremely thin and its very easy to mess up and ruin it, is it safe to do that still???
I also run an adjustable FPR on my X to increase fuel pressure to 35 psi at idle due to the fact I have 24lb fuel injectors.
Remember, when you increase air entering an engine you have to increase the fuel flow to avoid a lean engine check light.
New project: modifications to the Ford Racing TB are in the works; should result in better mileage and RWHP.
Preliminary data soon.
aldive, did you ever have any problems with your TB since you put it on?

would putting a stock mustang 4.6L v8 do anything?
^^^^ya, he doesn't haven't any for the 4.0 sohc right now
Yes, the Mustang TB is much more common. The only noticeable difference I found was that the Mustang TB creates a little more slack in the throttle cable.
It should be expected to need to remove the slack when installing the Mustang TB.
