Lightweight Rotors for Eaton Superchargers. fromStiegemeier Porting Services, LLC - Supercharger Rebuild and Repair

anyone know anything about this.

faster revs? less parasitic loss?

 

intersting....

 

im in to learn more ha

 

Guess ill sub while my blowers off the car

 

Sub'd

 

Hmmmm......sub'd

 

There's no coating on them so I wonder how they do with heat?

 

I gotta think there are bigger fish to fry in the battle for more power. Now granted those aren't real expensive so you aren't out much, but unless you are trying to skirt some rules for class racing I have to think you should be looking elsewhere.

 

Interesting.

 

Are those oems that have been cored out?

 

thats what i thought

 

Thats too bad, I'd love to see new high twist hollow core rotors.

Good to see more options for the SC crowd, I'm seriously thinking about sending my spare snout out to get liquid cooled.

 

i can see these freeing up a lil power because they are lighter, less rotating mass = quicker revs. i could also see these staying cooler aswell. i think its a good buy if you paired them up with a ported blower.

 

I would like to see what the cooling mod is. They said they made a a water jacket in the snout. They are protecting their product.

 

Wait did they have a price for the rotors? I could not find it do I emailed them.

 

I like the cored rotors. I think that would be a bigger gain than neutral shafts. For anyone revving high/small pulley this might be a great mod. **** I bet with cored rotors I wouldn't have had to change to 6 rib(no belt slip with lighter weight). Depending on the price I may consider this when/if I rev the **** out of my engine later this year.

 

Ok, Now I am interested in these.

 

Lighter rotors are faster the air gets in. That what I think. I am sure it will jump.

 

i wanna see what they can do! in for charts and dyno..... totally interested

 

wanna see more of this, looks interesting.

 

neutral balance shafts arent put in for performance gains, they are put in to allow you to rev over 7500rpm without having the stock cast iron balance shafts explode

 

I'd like to hear about the physics of this design, everything I've read about the m62 shows it is a bullet proof low tech design with some serious limitations. How much weight could realistically be gutted from the rotor pack? I can see a faster heat soak recovery, but I'm not sure how much parasitic power is actually lost from the mass of the rotors as opposed to the inherent inefficiency of the rotor twist and the basic roots type design itself. For my cash I like the idea of cutting snout heat in 1/2 and as a direct result pulling heat off the rotors via heat convection.

 

Id be worried about the wall thickness and them cracking over time with the heat cycling and vibs

 

It shouldn't have any vibration. If it does then get ZZP Supercharger Coupler that will prevent to get any vibration.

 

x2 on everything he said, i want lighter, heatsoak resistant rotors that have more efficient rotor twist
