Wasup guys,

I have been wanting to change my tb to a bigger size. But i am not sure which i want either the 62mm or the 65mm. I know the 65mm will run through gas alot which is not a problem but i don't want to have any problems with ideling or flooding. Tell me what you guys think.

def dont get a bbk tb. get the accufab single blade, if you think upgrading the tb is nesecarry.

 

Why whats wrong with a bbk tb. I actually heard people have had problems with accufab staying stuck open. Well tb isn't the only thing. Headers tb and injectors maf all at the same time.

just look at the 2. there is no comparison in air flow.

neither. single blade or nothing.

 

Have you seen hp jumps from the accufab tb? I see i can choose from either the 70mm or the 75mm. Is that too big? I also see they come with a Plenum? What is that supposed to do? I am new the the throttle body stuff.

i havent seen dyno charts. personally, a tb is a waste of money on a mild NA motor. if i were forced induction and had $ to blow, ide get the single blade. but the single blade will dyno more, if there is any increase at all.

 

sorry i keep replying i seriously don't know much about the tb. So you think if i add headers, injectors, mass air flow sensor and the tb i won't get the gain i would like. With the mass air flow do what size do you think i should get?
What mustang do you have?

i had a supercharged 96 cobra, with stock maf and stock tb. and with only 8psi from a vortech, i was doing 460rwhp. personally, you need to focus on full exhaust first. long tubes, off road mid pipe, magnapack exhaust. you dont need injectors, and maf and tb should be the last thing you do.
