Default Intake for roots supercharger?

Just curious if anyone knows of an aftermarket intake for an inexpensive roots type supercharger, like a 177?
The LS supercharger kits (Magna, Whipple, etc) are more than twice the SBC chevy kits. I realize production numbers would be low, but hey, Edelbrock made the twin carb intake. I dont think I've ever seen one of those.
I'm just thinking a carbed, supercharged, LQ4 would be a relatively inexpensive 500hp torque monster.

Someone makes a roots, I've seen it in the mags. I think it's a 6-71 though.

i wouldn't waste my time with a 142/177 blowers. there very old technology two lobe rotors. The new Whipple and Kenny bell blowers are three and four tip helix rotors much better efficiency.

Just thinking about cost. A 177, single carb could easily support 500hp on an LQ4 with a great torque band. And they're only about $2k.

im sure some co is looking at it, i have seen the 671 mounted on one
prob wouldnt be that hard to use a 4 barl intake, make an adapter to fit a mini blower, use an 8 rib balancer setup, or 6 rib, set it up for 1 belt to run everything-i made up one years ago doing this, it was for a motor that no one made a kit for-i was lucky i had a buddy who let me use his mach shop to cut spacers and stuff

A good head/cam combo will support 500hp on a 6 liter as well. If you're shooting for 500 only then I wouldn't waste time with a blower

You missed the key words "torque band". One reason I'm wondering about this combo is for marine use. I've had a boat with 525hp, supercharged (177) 454s. The torque at 2500-3500 rpm blew away NA 525hp 502 cid motors.
For low boost conditions a 177 would be big enough for a 6.0 and would be an economical combo.
GM has the LSA listed as a marine motor on their website, so I guess they thought a superchared LQ motor was too.

The 177, carbed LQ4 would be a cheaper way to get the same results.

Thanks for the input. I was able to find manifolds for the 6-71 but not anything smaller. The 6-71 is pretty big, it would be nice to find a 177 manifold.

ive considered machining a manifold to run a 6-71 blower on my truck. I dont think it would be hard to make something. hell the hawes engineering one you posted is all just welded. ive got six 6-71 blowers and also a 4-71 so if you decide to run a bigger unit i think i could let one of them go

There's another advantage to the 177. It's available with a ribbed belt pulley. You can just pin the crank pulley and run a longer accessory belt to drive it.
