so i was thinking about getting a plenum tb combo but ive heard that the tb really doesnt give you the hp, its the plenum, so realistically why would i purchase a tb and not just purchase a plenum ?

come on... think about it dude:

you can only suck in as much air as the smallest point in the pathway.. if you dont upgrade the tb your still only taking in 65mm worth the air.

just do both

I just bought a C&L plenum. Kept the stock TB. It is true that the intake elbow is the restriction of the 2. Unless you do head work or change the intake manifold itself, or install a power adder, there is little gain from a bigger throttle body.
I dynoed right after changing the plenum and it did lean it out enough for a retune. Its a cheaper, easy upgrade so everyone does it, needed or not.

Here are Accufab's flow bench number, and my commentary...

listen to cliffyk, he knows his stuff.

The t/b + plenum combo will gain you some hp's though but for the price it's the same as any other bolt ons

So if i post a link to someone else's proven work do i automatically know my stuff to? lol

hoss 302, if you have a good rep. cliffyk over time has proven to me that he will not post retarded info. and really knows his mustang maintenance and repair...he always seems to quote the service manual or equilvalent
