Just curious - has anybody made any semi-scientific measurements (ie not just "it felt like it helped a lot") of changes in TB flow or increased rwhp after cutting/beveling their throttle body as per the "Ultimate TBI 2" tech article here? Clearly, the thing will flow better to some extent, but I'm just wondering if anyone posted what that extent is... thanks if you can point me to some info.

 

Anybody? Of all the guys who have spent an hour or two grinding up their stock TB, no one has demonstrated gains?

 

my first one was worth almost a full mph through the traps, not much of an et gain at teh time since i was so skilled at spinnign the tire
blackbird305 picked up a little more than a full mph of trap speed with a better prepped one than i originally had.

later
