Supercharger: Kleemann vs Renntech vs AMG
I just sold my HPS kit and am installing a Kleeman Twin-Screw this week but I have one question.
Which twin-screw Supercharger is the most efficient?
Kleemann - uses the Autorotor brand from Sweden.
Renntech - uses the Lysholm brand from Sweden also.
AMG - uses the IHI brand from Japan.
I have attached an article from Kenne Bell explaining the differences.
Do you agree with the article?

It looks like from what I've read on the net that in terms of Power/Efficiency/Quality the rankings fall in this order.
1) Autorotor 2) Lysholm 3) IHI and 4) Eaton
Based on my reading, IHI SC's are basically copies of the Lysholm at a lower cost masss produced level that were installed in the AMG E,CL, S & SL models as described here:

War continues between Autorotor and Lysholm
I linked the heated argument between the Autorotor's Jim Bell of www.KenneBell.net) and Lysholm's Dustin Wipple of www.Whipplesuperchargers.com.

why does it really matter?
with proper considerations/build and component choices the ultimate efficiency of the supercharger isn't all that important to how much power you can make. Just buy a larger one if you need to.
that said- ihi is on my crap list right now. had a vf22 fail two weeks ago.

The basic problem with my HPS Gen II kit (Roots style) is that first off, it was poorly designed (i.e. Intake Port, Plenum shape, Cheap Intercooler that also blocked air from entering 2 back cylinders, lousy air-box, cheap pump) and secondly the Roots style as everybody knows is extremely inefficient and builds enormous heat. The lobes/rotors also spin in a different direction and forces air around the OUTSIDE of the case instead of through the middle of the lobes, thus requiring a bigger case and blower to make the same cfm. This longer path circuitus rout also causes friction and also air leak back into the lobe chambers when the air trys to enter the combustion chamber. The gaps/tolerances on the roots lobes are also not as tight. A forum member named TechTune spent a great deal of money to fix the kit components and is making much better power than the standard HPS kit but I spent about the same as he did and just got a used Kleemann twin-screw since Kleemann now uses the Eaton Roots style on their new kits as well. Most likely for cost reduction reasons rather than performance I guess.

Are you still intending to have Vadim Fedorovsky and his team do your fabrication and installation?
He and VRP are highly respected by everyone on this forum.
Why not simply utilize their vast knowledge to properly engineer your proposed upgrade?

you took my general claim and made it specific though- for your application the autorotor will obviously be the best choice. However, that is not to say that all types can't work as well as they need to under the right conditions. I reread the first post and it's clear that you were asking which one would work best for you-
if you ask me your best option is none of the above. if you are really serious about pushing the limits of any of those kits (which you would have to be in order to have it matter how efficient it really was between them) then you should most likely go turbo or centrifugal charger. You won't be able to use the low end grunt the ts could provide anyways unless you swap in a new solid axle and slicks, basically.

Thanks! I guess you decided to keep your twin-screw. That's what I was searching for and finally got from BillyBenz.
Do you know if your twin-screw has 4 male x 6 female lobe Autorotor or a 3 male x 5 female Lysholm? Did you ever get a chance to look inside the case?
I will ask Vadim to check mine.
