17 with 18 manifold thinking about adding BBK 85mm TB

[Skyrm_da]

I have a fbo 17 GT. I have an 18 manifold that’s ported. Would I see any benefit from going to a BBK 85mm or 90mm TB? I know there is some tune issues with the GT350 TB and basically zero gains. I’ve spoken to a tuner and they say the same, but I have to think my stock 80mm TB is a restriction vs my intake manifold inlet size of 87mm+. BBK is advertising 8-12hp gain without a tune. Also they say drivability is like stock. Any advice or experiences out there??

IDK about 8-12 horsepower increase. My stock TB has been ported to 85MM. I've heard only good things about the BBK but they are pricey.

I agree they are pricey and I’m not sure about the real hp gain from them either. I just was wondering if anyone has swapped on a BBK TB or sent any real world results from them.

I don't have a '17 nor do I have an '18 manifold, but I do have a BBK TB. I don't know what a normal TB feels like so not much help for you. It drives fine, no complaints here.

I have a Pmas 120mm

A bigger TB may help out then.
