Throttle body without new aftermarket plenum?

[Seraphitia102]

I'm interested in getting a 75mm Accufab throttle body but I was wondering if there's any noticeable gains in power and/or sound just with the throttle body? I know this sounds kinda stupid, but I don't want to get rid of the stock plenum because I like the "Mustang" symbol on there. C&L plenums look exactly like an elbow as with most other plenums except Accufab which has their logo right on top of the plenum.

you won't notice any gains...spend the money elsewhere

+1 for no gains

You seem to have a lot of money for mods Seriphita. Have you ever though of doing turbo or supercharger???

Little to no gian in power, but a nice increase with the plenum.

Throttle response will improve though.

When I put on my 75 mm, I noticed a decrease in response. I got a bad bucking. The TPS and PCM are setup for 65mm. The airflow is more when you step on it but the computer doesn't know that. When I got a tune he changed the anticipated airflow measures and now it is smooth. I especially noticed it on the 2nd-3rd shift. It would buck hard like it cut out for a split second.

Well, I'm not sure if I have a lot of money, but I do spend quite a bit for my car I've thought of doing a supercharger, but my Mustang is my daily driver and I'm afraid that a supercharger might ruin my car or decrease it's life.

what about just a plenum?... how much power would that add?... is the BBK piece worth a shot?... its the cheaper than accufab and c&l... ive been thinking about getting a plenum but dont know if its worth it

There was one test at like modular powerhouse I think on throttle bodies and plenums and with the stock timing, accufab plenum + 75mm accufab throttle body produced 6.Xrwhp. That was the best gain of the 4 being tested.

I think that if you're going to open your air hole a bit more with the plenum, you should get a larger throttle body to take advantage of it.

You have got to be more careful with how you word things around here. .....

If you are going for looks get the Accufab , it is at least polished. You are correct, there is not a lot of HP to gain.
You can get one of the SC that is shiny and only puts out 6-7 lbs boost or go with 9-11 and get a safe tune. You will hurt the engine, not the SC.
there is another plenum that is polished as well.

How about a ported stock upper intake? I see them for sale alot and were popular before the aftermarket jumped in. I think hp gains were similar to C-N-L etc with an aftermarket TB and intake spacer...just a suggestion since you like the look of the stock.
