I'll be keeping an eye out for updates. Not the easiest turbo bike to tune, twins are notorious for being difficult under boost.

I've looked at the throttle bodies a few times. trying to figure the best way to attach a plenum. The best idea I came up with was an extended bellmouth with "O"rings on the outside diameter so the plenum body could be slipped over.

Or remove the throttle bodies and run one on the other side of the plenum?

The frame limits everything, so I've made the decision to leave more engine mods until I have made a custom frame that allows me to work on the motor without removal.

I've got a set of EFR cams, but imagine a day at the dyno trying to dial them in!!! It'd be a long expensive day!

Keep up the good work, give me a shout if you need any help with ECM tuning.

Thanks and I will probably need some help with the ECM!

I needed to make the Buell street legal here in Sweden so I had to take the turbo off :-( Anyway went to the closest drag race track just to test it and have a base line. 10.82 was the best time slip during the weekend. Next time at the track will be with some extra power ; )

Absurded, the Browne's bike is a Little bit more extreme then my bike. Anyway the purpose of the big plenum is to smoothen out the pressure pulses of the V-Twin Engine. My plenum will work OK but most likely I will develop the installation a bit more during the Winter.

I've changed the injectors on the bike and have asked for the flow rate of the Buell 1125 injectors on other places here at BWB. I got a number of 35 lbs/h but this number is not confirmed and wanted to know if anyone have flow tested the standard injector and would'nt mind sharing the flow numbers?

I'm getting Close to a dyno run and would like to get as Close as possible Before I put load on the Engine.

Thanks Peter
