Why no Kenne Bells?
#21
Uuuum they do have a bypass valve, unless you are just saying that the Maggies have a different design of one.
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 have one on my c6. Most it put down is 550, but also i have 500+tq at 2k at the wheels with 11lbs of boost. In my opinion the heat exchanger is a joke, its tiny as hell. Meth kit is a must, only way that i keep my iats in the 180s and thats stop and go traffic. Where as if i didnt run meth they go just over 220. I have been looking for an upgrade, which I might have found. I beleive it was ECS that did a hummer for a customer in Dubai, it looked very promising.

The Kenne Bell on the corvette per say are junk, Now the Mustangs and the others on stock forum are good. I had the 2.8H on my vette had all kind of problems IAT where out the roof and the thing only made less than 650 rwhp. I pulled it off and the only diff put a A/A YSI unit on the car motor and made 857 rwhp on a Mustang dyno. I know some one said above that the Kenne bell pulls as good as the cenfi units. No way will the kenne bell do this on the top end. You tuner will have to ZERO out the whole table in the tune on the IAT with the Kenne bell. This is what jeff does or did in the past. Plus the way jeff lies about stuff cant believe nothing he would tell you.

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.

Sell it, go turbo.
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.

The vette kits aren't made by KB btw. Someone purchases the blowers from KB and makes everything else. I haven't heard of anyone complaining about the units themselves.

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.

Say that double for me man. After having now the YSI and seeing what the F1A will do in the vettes or any other car. I would never have nothing more in my car unless it was a ttix kit in it. Sure in the hell will never ever look at a kenne bell. After the vendor that sells them over in the corvette forum.

o sorry; so like a king size sharpie. the point is if the bypass worked correctly the s/c should cool back down, but they don't. it holds heat for some reason, usually because they are compressing (or in boost) all of the time.
