"I'm going to pass on a rotary engine with three moving parts and go with a Jaguar V12"
Said the guy who's desperately looking for ways to spend more time in the shop and less time with somebody.
Added later...
I'm a fan of the cat, may own one at some point, just wouldn't be my go-to for easy power.
Easy power would be a junkyard LS and Chinese turbo. But that doesn't look cool. Slingshots have always been about looking cool and going fast as hell with a differential grenade under your nutsack. And there's nothing easy about that.

Time to take it racing!
That's actually my idea for the coolest hotrod ever. Replace the FI with Webber's though (you know, to add complexity!)
Those guys with the blown V8's think they are cool, wait until to you roll up with 12 zoomie pipes and 12 throats of carbs sticking out of the engine compartment!

Throw that same Chinese turbo ( or two smaller ones.) on a stone stock V12 $300-$500 in junkyards. Except you can often buy them much cheaper. Using E85 and you're around 600-650 hp. Put a reground pair of cams on it and you're another 100 horsepower up. ( stock total lift is only .375 or 3/8ths of an inch. )
Cams on V 12 are right on top.Remove the valve covers and there they are. Not buried behind a water pump or other junk. They have a notch in them for a little piece of stamped steel to set cam timing. And a bracket to hold the cam sprockets tight so you don't need go fishing for the cam tensioner
no push rods, no rocker arms The cams push down on the lifters separated from the valves by shims used to adjust clearance. very easy to do.
Everything else looks like a top fuel Chrysler except 12 holes for pistons instead of only 8

Why not make your life simple? Toss a GMC 6-71 on top of the manifolds with a Holley dominator on top of the Supercharger?
I think its cool just because its different.
But... I have to say i cringe when I see zoomies that are not tied together. In my youth we had a death at our local strip when a pipe broke off during a launch and the tire shot it back into the crew.
There have been many bad ideas posted here 
Following.

Not that one. Too nice! It's a good buffing and some detailing away from a nice profit or a really high speed cruiser. It's a legitimate 150 MPH car Stock!

No way, that's to easy! The theme is more mechanical mayhem. Now if you want to put a pair of turbos on each side pulling through some side drafts, that could be interesting.
Hmmm, I wonder if you could setup Weber's as blow through, one per cylinder. Now that would be crazy!

V8's have a second order harmonic impossible to eliminate. When you add the required radical camshafts the shaking and vibration will cause those problems.
A V12 on the other hand is turbine smooth. I used to balance a 1/2 dollar on my race car engine with the wildest camshaft available.
Smooth defines V12's

I like Easy. Remarkably a V12 is really simple. Just times 12.

Hi frenchyd,
Thank you for sharing your experience.
Again, I'm a fan of the cat.
Right now, I'm a middle aged man (56) living the life of a younger man (two daughters, 12 & 15), med-tech career (2019 = 75+ hours per week, 2020 was supposed to be easier but COVID-19 put an end to that) . Right here, right now, I'm just hitting as many "Easy Buttons" as possible (I daily a 2019 Mazda CX-3 because it's a fun little scamp that asks for nothing). I'm in my last few years of "deferred gratification"...after that, if I want a Jaguar, Porsche, something that has spinning triangles, some combination of the three, whatever, it's all good.
Hopefully, you'll be active on this board at that time as I would greatly appreciate your guidance if / when I decide to treat myself to a (Jeremy Clarkson voice) Jauuug.

My favorite is still Mickey Thompson's slingshot where he took one of those Pontiac half-a-389 194.5ci slant-fours, chopped it in half again for a 97.25ci inline twin, then bolted a Detroit 2-71 blower with a single Hilborn injector to it and made 250hp. Because Mickey Thompson.

Do yourself a favor go to Facebook and look up Robert Knodt he has a weekly Show called Camp Chaos .
Right now he's starting a complete rebuild of a Jag V12 with a $100 budget.
There are loads and loads of cheap non running Jaguars because people are just too lazy to learn. fuel injection works pretty much the same no matter what it's on. Details like sensors etc can be found by watching U tube's 3 part series.

Guys like Mickey Thompson remembers the basics. Engines need fuel, air, ignition and timing slice and dice and they all work the same.

You can but it's tricky. The throttle shaft needs to be sealed, usually done with an o-ring on each side, so you're not spraying air/fuel out the carbs under boost. Trouble with Weber's is the space between the barrels is really tight so cutting the body to fit the seal is tricky at best. Luckily, you can buy them already set up for blow through. Not cheap, but nothing looks cooler than Weber's.

In reply to barefootskater :
The problem I have with an idea like that is the conflict between classic and modern. While I love the appearance of Weber's and enjoy solving the tune up dance required. They are classic. Elegant but antique
Turbo's really do work best with EFI. yes you can kinda kludged them to work with carbs but at a cost. A cost of power drivability and potential damage to the engine.

If you truly want mechanical mayhem you should look into steam. Reciprocating steam. There is some really wild stuff there. Hence Steam punk!
In reply to frenchyd :
Compromises for sure, but if the goal is looking cool and being interesting and unique...
And, as we've already established, if you want the best of driveability, reliability, cost, and ease, well, it's just another turbo LS.
