Sal I'm not trying to start a tuner war. I thought I had a valid question, but I guess we are not allowed to ask those??
It just doesn't seem so logical to me and thats why I asked. I was under the impression these blowers were equal in displacement and the Kenne Bell had a plenum area behind it. That is why I asked the question. Just because someone says it is better doesn't make it better. By the way thanks for all the civil responses. I knew a few people would have there mind in the gutter....
Thanks Mike

BlackBolt: You can Contact Jim Bell @ KB and explain why you over SO Many others are more Qualified and have the Righ facility and Equipment to Conduct The Right Test for the KB & 140...Do you know how many people have asked to get a KB to conduct a *Test*? Like i said this test took place in Sweden Where both blowers are manufactured..The test results are what they are...The Next test will be the flowzilla vs. the 140 intake design...I believe the flowzilla will surprise us all as well.......JL

Sounds to me like this test was done on a bench with just the blowers and not with the intakes and all the other working parts.
I find the following reasons funny why these results pop up now...
1- Cali posting his nice DYNO #'s with little timing and low boost
2- KB being called out many times
3- WORKS products showing less defects
4- WORKS not knowing this took place and its total BOGUS.
If anything was tested it "MAY" have been a BARE blower. This is not a true test and I am amazed at the level KB/JLP has took this to. I dont think anyone will not buy a WORKS/KB blower if there ever is a 5% differance between the two. It will be a personal opinion. Both Blowers are nice, but the cheap shots have to go. I will say this with pride, NO WORKS OWNER HAS SAID WORKS IS BETTER THAN KB. We simply have posted Dyno Charts and #'s to show how well it "WORKS"
This is really sad to see the level a great tuner has taken it to. The influence has started.

I can't even ask a civilized question
Heres a rephrase:
Forget the Kenne Bell and Works, how is the rear entry more effecient than a top entry given the same displacement and a plenum area behind both rotor packs??
Thanks Mike

Here you go... Sal sumed it up well....
As for the top vs rear inlet, the rear inlet is more efficient. Axial screwchargers are designed to to injest air from the very back or the rotors, and compress it forward through it's screw rotors. When you have a top inlet, two things happen. One, is that the inlet itself reduces the overall surface area of the blower, reducing the displacement of the rotor pack. Just like on the stock Eaton, it's a 112 ci rotor pack, but the actual displacement of the blower is more like 95 ci or so. Two, is that with the sides of the rotors exposed, the incoming air gets "paddled" by the moving rotors, and the turbulance causes the incoming air to be heated up from being beat up before it actually gets injested into the rotors. There are two prime examples of this. One example is the new KB blower and the Works 140. Both blowers use 2300 cc rotor packs, but the top inlet on the KB makes it 2200 cc's, not a true 2300. It's a minmal difference, but it goes with what you asked. Also, if you look at all the data that's been posted between the KB and the 140, the rear inlet 140 makes more boost at the same rpm as the KB, showing the benefit of the rear inlet. The second example is the Lightning's 112 Eaton vs the 03 Cobras 112 Eaton. The top inlet Lightning 112 maxes out at about 18 psi, MAYBE 20 if you spin the HELL out of it. But the rear inlet 112 on the 03 Cobras, are hitting over 22psi.

Mike (TTRanger), my statement was not aimed toward you asking your question. I welcomed your question, and I have no problems with people asking valid questions like yours. My statement was just a personal observation that the "answer" to your question was going to through this thread into termoil. Sorry for the confusing, and if you have any more great questions, please ask.

No big deal. I was more concerned about why the top entry was at a disadvantage over the rear. I just used those blowers mainly because they were good examples.
So if both top and rear entry blowers have plenums behind the packs the theory you explained is still correct, right??
Thanks Mike

Bench racing schmench racing..........take it to the track and post some numbers. I agree with BLackBoLT99........the ONLY way to decide which blower is better is to take one of each to the track/dyno and use them on the SAME truck. Our trucks are set up too differently to compare say Dale's numbers to JL's numbers.

I called Works and told them about his thread, and they said there are only two 140's out. They thought the the whole thing was pretty funny. Who in their right mind would believe JL? and think that Works would sell a unit to a competitor before the kits are ready for sale to actual customers? And who thinks just because both units were tested in the same COUNTRY makes it a valid test? Yes both blowers are made in Sweden. Both Fords and Chevys are made in North America. Does a secret test conducted at Chevrolet proving that C1500's are better than Lightnings, prove anything? Other than that the people doing the testing are skewing the data, that is

Works may only have two 140's...do you not think there are other barebone blowers out there that haven't been adapted yet? Works is only taking a blower and adapting it, they don't build them.
