LS9 Corevette Engine, Supercharged

I hadnt realized the technology had made it to that many vehicles already. I bet its pricey as all get out, but I wish it would make it to the aftermarket areas..
 


I found a picture of the rotors. 4 lobes it would seem.

Definitely so. But I also think they use a different process even on the Gen 5's than they did on the Gen 3's. Farnsworth seems to have the contacts there and perhaps would like to do a write up or something on it, maybe something we can put in the how to section as an informational piece.
 


Thats the same coating as whats on the GenV's for our cars.

Eaton learned their lesson on the GenIII's as to what NOT to use for a coating to make a good seal. When I start rebuilding all my GenIII's they will have a different coating applied to them than what came stock.

The new Eaton TVS blower uses the same style of 4 lobe, screw type rotors on this blower.

Been working with a local Eaton distributer friend on getting my hands on a TVS blower, much like the style of the GenV M90 picture we have all seen. Tell ya now, the casting is different for the main case...let just say, they are proud of this blower and whant everyone to know what it is when you see it. ;) It will of course be polished before it goes on.

~F~
 
Farnsworth, you better keep us updated on all that. Its too bad you dont know how to or know someone that could update our rotors with the newer coating. Id venture to say that there is some money to be made there.

Do you have any information on what the Gen V rotor coating is?

When I went to the Topeka Nationals this year, Everytime they took the blower off those cars, they sprayed it down with what I could swear was some type of lubricant. Like WD-40, but wasnt that.

I would think that anything fluid but not compressible would seal the gaps between the rotors and everything else, thats why our Sc'ers are more efficient as they age because of the carbon in the case?
 
I would agree with you on that point, but what they were using was still really fluid and didnt stay in place. It wasnt a cleaner as best I can tell either because they never wiped the rotors down. In fact spraying the rotors down with whatever they were using seemed to be among the last steps they did with the supercharger.
 


I dont believe so on both counts. They had the blower completely off the car and doing all this. I have some pics somewhere because it really tweaked my curiosity. I'll see if I can get them uploaded.
 
Its actually a standard screw supercharger with a well thoughtout very integrated intercooler. They increased the cylinder wall size to handle the pressure hence going from 7.0 to 6.2.
I've never seen an engine design where they cover the supercharger is covered by the engine shroud. The "I wanna see da blower!!" loyalist can get upset all they want. To me this is ingenious and modern!

Ls9 - Jalopnik


I can't express enough on how happy I am to see this type of innovation comming from an American auto company. It was frustrating to see the cheap plastic interiors with unshaved moldings (ex. Dodge) and old uncompetitive technology just to please loyalists who don't even by the cars.

I see only a small handfull of folks swaping it out for a turbo as removing the s/c from that engine doesn't look worthwhile and beneficial. They'll do it just to say they did.
Most likely people will just decrease pulley sizes.

EDIT: Doh! I only read page 1. Well, the link is still useful :(
