roller barrels eliminate the "flutter" that is caused by the throttle butterfly.

even with a knifeedged butterfly there is still a minor disruption in the airflow, so the rollers cure this by not having a butterfly.

also they look very trick ;) although they cant be that hard my mate designed one for a formula student last year, and hes also designing a set of 6 using a drin pipe, must on to him how to design them lol

so yeah they are good, not too common as yet and well worth a go imo.

they are very nice looking the only real prob is that lumenition cant give me any bhp figures usual rubbish bout depends on engine spec and fitter etc! surly they can deliver just as much as a tapered throttle bodie? :wink:

Well for what its worth I've been told that the cheaper end of the job don't produce any extra and aren't good VFM. Swindon developments have done them but they cost ?000's - all in all probably more cost effective to stick to std ones. If there was a big advantage cheap enough most peeps would be using them?
