Hi-Boost Kleemann Possible?

This is mainly a question for the evosport/kleemann guys:

You always say how your supercharger is low boost, and puts out the same amount of power as the renntech(high boost) system.

You also say that the only way rentech's high boost application can work is by beefing up the engines internals.

My question is: Would it be possible to run a higher boost on a Kleemann supercharger with beefed up internals?

And if so would this provide a significant increase in power?

Thanks
Asa

We are currently doing both of the above in combination with a heavily beefed up motor; our 6.3k.

I am currently running my CLK32K at maximum 0.75 bar...
So far so good, great power increased....

Alexyu, any dyno results? Who made the crank pulley that creates that much boost, and does it have the dampener still?

The boost is not increased by enlarging the crank pulley. This would lead to too high a shaft speed on the SC. The EvoSport 6.3 Sleestack machine will have a new SC rotor group of a higher displacement.

(1)The smaller s/c pulley the more boost ......Kleemann S/C
e.g alexyu & a few Kleemann members here are playing 0.75 bar
significant gain in acceleration & 0~100 mph sprint time

(2)The larger crank pulley the more boost.......AMG or Carlsson S/C
e.g Evopsort ODPS for C32AMG, Brabus K8 for SL55, CM32K

The margin is how NA cars afford extra boost w/o enhence
several key parts of motor.
MB NA motors is robust to take 0.75 bar , IMO
AMG S/C motors afford much more boost but how you compensate the ecu/MAP ? a capable tuner is needed.

As KLEEMAN was saying,

there is a definite limit to increasing boost with higher blower speeds.Once you get there,further increases simply consume more power and heat the air.Blower sizing is critical...get it right,and you'll have a wonderful powerplant.Be greedy and do it wrong...look forward to a long trip home on a tow truck.
