Trick flow to release blower for the Lsx!!!
KB 2.8H with a LS2 402...Here you go..
YES, there will be a twin screw blower for the F-body. Its just taking time. Te 2.6KB is structuraly no bigger than the maggie mp112. What **** us all up is the inlet tube, and the bypass valve. But we are trying a few little things to correct thos obsticles.
BTW, we tested the whipple 3.3L against the KB2.8H. same motor, same boost, same RPM. The whpple made LESS power.
Its simple physics. The rotors need to spin at a certain speed to get within the relm of optimal efficiency. The 3.3L blower (Which KB has as well, its just a prototype) is just to big for the current motors. You cant get the rotor speeds high enough, and alow the motor to breath well enough to make any significant change.
We wont even go into the structural integrity on the cast case with rotos spinning at 15,000rpm's..LOL
Is that an F-Body setup??????

what i think is still goin to be the difference maker is the whipples can go to 50# and 30# respectively
ok last thing are you goin to make an LT1 kit?

If they put an aftercooler on it, it will raise the blower up which will screw up the fitment under the cowl which defeats the purpose.
You can always go with alcohol injection which is really effective.
I'm sure it still makes great power and awesome low end torque and at the boost levels that most guys will run on the street you wont need to aftercool, you'll probably need it when you go to real high boost. That's my theory and I'm sticking to it.

Sure, on cool days and nights the IAT's are considerably less but again, once it heat soaks, it's a big hit.

Hope you are correct but I don't think so. The IAT's in these types of blowers are typically 140 -150 F and on full boost, lap after lap, I bet it gets hotter...lots hotter.

And, just for arguments sake, what's the difference between the Maggie built-in inter-cooler and the KB built-in inter-cooler. Sounds like you have all the info.

So what are you going to do to test the IAT's - one or two dyno runs ? Please enlighten me on your testing methodology. Maybe you can can snag some useful data acquisition equipment from the city and fill the airwaves with real data. Good luck but don't quit your day job.
What about the question regarding the design differences from a Maggie and how you were able to unequivocally state that a KB was much cooler?

^^^efficiency/iats between roots and screw blowers isnt really new stuff......im suprised were even having this arguement.....there a reason most people go with screws....
....but im a noob, what do i know

It's taken me some time to get the car running, had some major changes and setbacks, like a twin 76mm alcohol setup that sold due to unforeseen fueling issues at the last moment before startup.
well i am running a standalone ems so i can wire in a second IAT sensor in the intake piping and then the one in the manifold and log the difference in temperature between the 2 over the countless pulls it'll take to get the car's tuneup set.
then i will also be able to do full logging sessions while the car is being driven to check the effectiveness of the airflow over the supplied heat exchanger. Yeah it's not going to be 100% accurate but it will be close enough to give real world driving results.
The only data acquisition equipment i have available at the city is for water flow and turbidity.
My statement come from the design of the blower.
1) the kennebell rotors do not touch and do not require seals that generate heat due to friction.
2) the kennebell uses a larger intercooler core than the magnusons
3) the kennebell compresses the air to the front of the blower and does not circulate it around the edges of the housing.
4) the larger displacement of the kennebell will flow more air at lower rotor speeds than the magnusons.
If you dont believe me then be my guest and read the white papers published by both Eaton and Opcom/Autorotor/lyshom about the efficiency differences between conventional 3 lobe roots blower, 160* high helix "TVS" blowers and the Variable Lobe Twin screw designs.

As for countless runs to dial your setup in - better have a source for LN2 to keep those IAT's cool enough to run more than 2 degrees of timing.

You need to ACTUALLY do something instead of blabbing on this board as IF YOU HAD DONE SOMETHING. Again, you do a shop owner huge dis-service. Keep your day job and be careful not to get caught on the internet instead of working.
Another stupid statement.
