throttlebody differences
 

Hello everyone. Has anyone tried more than one type of throttlebody/upper plenum combo and seen a difference in performance? I was thinking about trying trick flows 70mm throttlebody since I have their upper plenum. Any advise?

You won't see a big enough difference to justify spending more money on 1 brand vs. the other. I run BBK with C&L plenum.

PP t/b and plenum 200 bucks, was a good deal IMO

I picked up a spare stock TB and plenum off ebay for $13 shippedand had itmailed straight to a machine shop who is porting and polishing it right now for $100. Both will be ported to 70mm.
