I am looking to get a combo throttle body/plenum. I am deciding which on http://www.rpmoutlet.com/newv8cm.htm . See the plate on the Accufab, C&L and BBK? The BBK plate has an extra hole in the plate. Is there an advantage/disadvantage to this?

 

bump

 

its actually not a hole, it doesnt go all the way through. That is where the IAC bolts up to. On GT's there is only one hole. On Cobras and i think MACH 1s there really is two holes, althoght im not sure why. (i guess its possible that the picture is of a Cobra Plenum)

 

ACCUFAB TB/PLENUM CONBO--30-40 HP GAINS

 

2 holes for 4V engines (Cobras) , 1 hole for 2 V engines (GT's)

 

30-40???? more like 10 15 if your lucky lol

 

Yeah, that sounded high, so i'm guessing the BBK on that website is a cobra plenum?? Anywho, i'm gonna order a combo soon, thanks for the input!

 

your kidding right so according to that theory of yours my stock 260hp mustang with just a tb/plenum is almost if a 300hp car now. bull**** no way if thats the case im pushing like 350- 360 horses right now. cobra killer here i think you got your facts wrong id agree with 10 -15 hp if not a lil more

 

Accufab all the way!!

 

more like 7 or 8 hp actually.

Accufab makes like 7-8 hp the rest like 6-7 hp. Hardly worth the $300 or $400 your gonna spend on it while their are other mods that are cheaper with better gains (like exhaust, pulley's, tuner, CAI, etc.
