blower style

RE: blower style
I'd stay away from weiand sc's for a street or street/strip car if you're aiming for efficiency.
As far as fuel economy if the roots s/c kit is setup right, very little fuel economy lost. You'll lose a bit more with the twin screw.
I didn't say nobody makes one. I said i was pretty sure there wasn't a kit. I didn't know if there was a bolt on roots kit or not.

KB is probaly your best bet, because of the twin screw design they are better than roots blowers yet they still sit on top of the enigne.

I believe weiand is still using the straight rotor design which isn't as efficient, but they can pack in a higher volume of air using that & a top to bottom design with a big case. Good for strip cars where fuel economy doesn't matter & you have an engine built for needing LOTS of air with a low p/r, not so good for street cars. They could have made some case modifications though to boost efficiency it's been quite a while since i've looked into weiand's designs.

I was saying in terms of actual design the twin screw is superior to roots, they use less engine power, run cooler, etc.

& to top it all off, because the roots doesn't compress air inside the case, installing a bypass valve equalizes the pressure so the s/c will freewheel while the valve is open (like while cruising) so fuel economy doesn't take a hit.
The 4 lobe design hasn't been around for all that long so you probably won't find much comparison until it's available in kits. But you can look up on it by googling "eaton tvs". I believe magnuson is producing them, their 6th gen ones are based on the tvs design.
Here's one on a gm ls series engine
