They're the butterflies for the short/long runners in the BBM and I believe that doo dad thingy is the actuator for them.
Being turbo, I'd be gutting the BBM and removing that stuff while you've got it apart. |

No. Butterflies are used to switch between the runners in the manifold. Long runners at low rpm for torque, then IIRC they switch over to the short runners for more top end power at roughly 3800rpm.

Yep, with a turbo they are pretty much pointless. Remove them and do a little porting while you are there.

yep I allready have done it justin! Quote:
As for your other thread about changing injectors... a couple of questions. 1. Are you running a aftermarket ecu?? 2. Are you running a rise of rate FMU (fuel regulator). If you are not running a after market ecu the stock computer can't handle bigger injectors without a flash tunner even then the capabilitys are very limited. Also you can run a max of 9psi only as any more the map sensor will shut down the whole system. If you have any Q's or anyhtingt feel free to PM me and im happy to help out. Tristan
