Boost Bypass

[GROUNDSTRIKE]

Jim I put on one of your flip chips and mass air/filter kits. Runs real strong now and shifts great. I do have a question about the bypass kit I bought. You've probably answered this before but here goes. I know it's more efficient to have a bypass valve. Keeps intake air temps lower at cruise and idle. I think it's one reason that the eaton with it's built in bypass valve is chosen alot over the whipple by oem. Does the bypass kit take the bypass valve completely out of the equation? Does the bypass valve no longer function now at all with the kit? Does this affect cruise air temps, fuel mileage, and idle air temps? Could it cause detonation at take off after extended idle (long stop lights)? I guess I'm asking what are the negative affects? I know it's a popular upgrade to go to a bypass valve on the whipple. I don't want to second guess you but sometimes not all the products are for everyone. Thanks alot for your time Jim. I chose your products because of your reputation, and have been pleased so far.

researched?

Well I did some more reading and it looks like the boost bypass kit just drops the vacuum source to the actuator that can affect the bypass valve. And the bypass valve works like stock even with the bypass kit and just removes the ecm's ability to affect boost. Is this right?... Some info is conflicting... Also there is some confusion as to if this will increase boost response (more boost off idle).

You are correct sir. The only thing that will affect boost is the actual boost wastegate (dump) and that is easily adjusted. Here's a picture of an adjusted wastegate by Mr. D'Amore ...

This adjustment makes sure that the little butterfly blade ( it's like a small throttle body blade ) inside the blower is fully closed once boost kicks in. This insures no boost drop off what so ever
