  I can do a stock 2010 and 2012 if you would like

Well if you are taking requests..  :smile:

I think that it would be interesting to see how much different the stock head flows with a stock and modified throttlebody.. Kind of gives you a idea if any more power is available by just changing the TB (and tune).. With that in mind the comparison should be the same TB MPN.  Some might also be interested if the 12 flows better then the 10 on the heads because they might be able to pick up a take off 12... I'm more interested in the stock 10 vs the modified 10 TB on stock heads...

Thanks,
Max

Are you using the HPI 54-58 bored out throttle body?

TorQuePimp

 Used for testing was a reworked factory throttle body

what is seen here is not like haveing a throttle body on a running motor on a dyno and pull the backplate. you lose big everywhere.

They're out there, I just saw them but can't find it..
I've been searching TB's for the last few days..
I decided on the J.E.T. port and bore to 48MM for $169..

I've found just TB flow numbers. But was interested in this experiment that utilized stock head and the 54mm modified OEM TB, and then the same test with the unmodified OEM 50mm TB. I haven't come across those numbers anywhere yet.

      Kinda swamped honestly,I have a set of stock heads but the 50's I had both the 2010 and the 2011 were sold or sent to s&s to have the electronics swapped into a throttle hog.

  If someone has a 2011 that they don't mind loaning out ill do the tests and send it back.

I have 2, but unfortunately they're on bikes... I have a 54, but you have that covered. I'll look around....
