just wondering if anyone has the 70 mm bbk throttle body from summitracing.com....seems like a great price which makes me wonder about performance. Also what was the order number of the item cause there are about 5 all for ford 4.6L. thaaanks

I have 75mm BBK TB's on my '01 and '00 GT's. What's the price from summit? I have had no problems with BBK and the 75mm's go for about $179.95

I just bought one for my talon. The mustang bbk 70mm fits my intake manifold. It made a pretty big difference, however, Im turbo...not sure how well it does on an NA. One of the guys in my club has a 94 GT. He has the 85mm on his car...and it runs like crap. But I think 70mm is a good idea for your application.

aight cool...yeah code3 the price for summitracing. com was about the same give or take 5 bucks. How do the cars run on the 75mm?? Do u suggest i go with 75mm instead of 70mm??

Yeah i have the same question about the 70 and 75, i think the 70 would must likely be a tad bit more efficent for 4.6 but im not really sure lol, i have an 04 so thats what im leaning towards.

70mm is perfect for NA cars

I have 75mm, got it because it dynoed better when combined with the C&L plenum....Thats the setup I got and they did that on a N/A GT.

A tb is not going to do $hit without a plenum. I had a bbk 75mm and felt no difference.

EBAY EBAY EBAY! Look there. I got my accufab (best brand in my opinion) off ebay for $80 shipped. beat that!.

i have a bbk 70mm and the shaft that the butterfly(blade) bolts is broke in 1/2. It sucks because I called BBK and they dont sell the parts seperate. I guess I will have to get someone to braze it or drill it and tap a new hole in it.
