Low profile roots blower options LS3
« on: March 03, 2019, 11:09:16 AM »
What are some options for a roots blower? Using the samberg k-member/cradle and stock hood.

Prefer not to get a cowl hood if possible.

Also read the dodge demon are breaking diffs. Does the diff brace make that much of a difference?

The TVS blowers are about the lowest profile available. Height also depends on how large the heat exchanger is, either way you're going to need a cowl. Even the corvette it came from had a cowl.

Dang. I like the sleek look of the one hood.

There isn't one that fits under the stock hood otherwise I'd have one.

The closest you get is the magna heartbeat. I think it's about an inch taller than a fast102 which means 7/8" of it is sticking out of the hood. The fast is a couple pieces of thick paper from touching.

Even if you ran without motor mounts and moved the rack down I think you'd still come up a hair short.

I've been thinking about this as well and having a hard time finding a way to SC the motor with a roots setup while maintaining the stock hood. Right now I'm thinking GM's solution  for the new vettes might be the best option and that is to create a shaker hood for the FD. Designing one that doesnt ruin the sleek curves of the car would be difficult though.

What if you could relocate the supercharger to the front of the engine?  Would take care of all the hood clearance issues!

You mean a centrifugal style?

I kinda like the low end character of the roots style

Save money on the blower and get the most CI you can afford

I picked up an LS7 rotating assembly with billet mains for $1100. Just need a block now. My only fear is when I pick up a sleeved block, will I regret having not gone to a 440 or something. MOAR CUBES....!!!

Anyone need some really good sub 400ci heads? :-)
