Why no Kenne Bells?
Kenne Bell and Whipple are pretty much your top of the line positive displacement type blower, then comes Maggies with their TVS followed by all the other TVS blowers, then the regular Eaton based roots blowers.
Hey OP what size KB blower did you go with? 1.7, 2.1, 2.2, 2.4, 2.6, 2.8???
I agree just not worth the problems when the thing dont make the # then the customer is thinking it is the shop who ever the shop will be.

Na thought of the joke at the moment. thought it fit. ive done one maggie and a couple turbo cars. turbo is the only way i will go if i am not building a pickup tq monster. then i would do a s/c.
It seems KB has changed some over the years, especially when they started making their blower in house versus using Autorotor blowers. Back when it was just the 1.7, 2.2, and 2.4 the quality was really good and they made GREAT power and IAT's were manageable. Back then they always had GREAT product but lousy customer service, and straight up lied about a few things back then too. I don't have any direct experience with their big bore 2.6, 2.8 and whatnot units but it does seem people are having more issues for some reason. I am willing to bet that when they started making their stuff in house that quality control may have become an issue. Just my guess looking at the situation developing over the last 8 years.
The TS's do always compress but while the vehicle is idling or very near idle the blower is not supplying enough air for the engine. So the vacuum bypass diaphragm is hooked up to manifold vacuum in the lower intake manifold. Once it senses vac then it sucks the vacuum bypass open and you are pulling in air around the blower itself while at idle or very mild part throttle.

What IATs do the Ford guys see? I see them posting about 700/800+ rwhp from the big KB blowers on GT500s/Cobras.

I wouldn't call the T/S a better design over the roots, it's just different and has its own pros/cons. For all the talk about efficiency on the T/S they seem to produce a lot of heat.
Sure in the hell will never ever look at a kenne bell. After the vendor that sells them over in the corvette forum.
