Looking thrugh my sponsors website, i found these Lumenition throttlebodys

http://www.free-tuning.dk/Free_tuning/cata...pID=983&invis=0

Im not quite sure if this is the right forum, but i do know there are alot of people into flow and dynamics who is just dying to tell me whats the deal with these

For street use i dont really see any advantage as the roller inside is just a big obstruction in airflow, for racing though they seem pretty interesting as there are no throttleplates to mess up the flow.

Did I just answer my own question????

I think so!

I have read part throttle response is poor with barrel type throttle bodies.

I was at a dragrce/showevent back in June, sucking up to potential sponsors and stuff

I met this fellow dane who made the Optronic ignition system http://www.lumenition.com/PMA50ins.pdf

Turns out that he made a customkit for a friend who used to work on a rally FB, with great results.

He now produces oil additives for all kinds of applications http://www.abcon.dk/

Which reminds me to suck up to him some more
