throttle body 50mm or 54 mm
Im getting ready to have a set of zippers 575 g cams installed in my 05 FLHRSE2. What about the Zippers thunderjet throttle body and manifold while I'm there, would you install 50mm or the 54 mm. along with the zipper aircleaner kit and larger injectors? How much performance do you really get by adding these products? Any feed back would be appreciated.

RE: throttle body 50mm or 54 mm
Larger throttle bores would kill bottom end performance because the vacum would drop and a carb could not pick up enough fuel Thats why they have accelerator pumps)to keep the mixture right. This is less of a problem with fuel injection, but still affects performance. I would go for the 50 so that I would have a little more torque in the bottom end. If you are not sure call Zippers and tell them what you have and they will reccomend the proper size as they have numerous hours of dyno time with these.

Thanks guys for your reply, I went with the 50mm tb, and now I'm installing the D D Fatcat 2 into 1 system. Now, the questions is do I install the standard baffle, or performance baffle/hi flo baffle. Not sure what they call it. Does it make a big difference? Has anyone tried these baffles? thanks for any response.
