HP increase
I have a 1991 mustang GT(AOD). so far I have installed: BBK headers, Flowmasters, hollowed out the cats, 410 gears and a turbo shift kit. I want to put on a BBK cold air induction kit, and a bigger throttle body. My question, which Ive had mixed answers too.... Will changing the throttle body from the stock 60MM to a 70 MM make much of a difference than going to a 65MM, will it cause flood out, and do I need to change the Mass Air Flow sensor too? HELP !! what is the right answer? Ive been told a 70 MM will be overkill, that I will not see a noticeable change between a 65 and 70 MM, also I was told a 70MM would cause It to flood out? I was also told I had to upgrade the MAF sensor to get adequate increase in HP? Will installing a bigger throttle body with the add ons Ive done, plus installing a Air Induction system, have noticeable HP increase ?

RE: HP increase
when i say noticeable im not talking 30-50 increase , im looking for an easy 15-30increase, Ive read and taked to several people that the cold air kit with my mods ive done could get me 12-15, would a bigger throttle body give me 10-15 more, or would it be a waste of money?

RE: HP increase
dont worry about a cold air, the stock air box is fine, its already pulling air from the fender. as far as tb size, i would say just go w/ the bigger one, it will save you from buying another down the road. 65 isnt that much bigger than stock anyway.

RE: HP increase
well i would think putting a bigger TB on a stock manifold opening would be pointless. Maybe i am wrong but i just got a cobra manifold and that opening is 65mm. So putting stock 60mm back on would be stupid. I would think it would apply for a bigger TB and stock intake opening. Could be wrong though, but it does make sense. why would you open up the TB if the manifold wont use all the extra airflow to it's full potential?

just remove the air silencer in the fender well and install K&N filter in stock air box.
