Re: Twin Supercharged Miata Build (56K Beware)
You get a A- for effort, but it seems futile that all the effort is going towards two blowers... 1 Turbo would be much more effective... Fabrication, time, and financial wise. Why wqaste all the effort.... ---- even a small t3/04e will get you your goal, look cleaner, not be cluttered, and far less ------y going on... Im all for different... but this... I dont know man... God luck though

Second SC is going on the exhaust side above the header I haven't built. These blowers are twin screw SC's, which are more efficient than a roots blower. Plus they're 35 bucks each at the junk yard. 
SC hardware stuff will be labor intensive, but not too costly for the HP capablilty it will allow. How much does a 500whp capable turbo seutp run? And then it would take forever to spool. Both SC's will be pullied the same. The outlets will merge into one 2.5" pipe and then in and out the IC and to the intake manifold. They will spin 1:1 ratio with the engine. 
Course I can alway s pulley up. These will make up to 29PSI, but are pretty efficient up to 22 PSI. Problem is one SC won't hold 22PSI to redline unless I pulley it to spin 20K snout speed. It wouldn't hold up at those RPMs and would blow a lot of hot air and pull a lot of power from the crank. Two should actually be more reliable, as they will spin slower and run cooler. Also two will use less HP from the crankshaft above 250whp as opposed to 1. Ideally I'd use a larger 1.8L SC or something but these are cheap and I wanted to see if I could do it. Many people talk about putting a millenia SC on there car. Nobody ever does it though.

seems like ALOT of work for the performance gained... DOnt expect a shole hell of a lot of people to think differently.... Dis is HMT nukka

So I'm working on building a ghetto intake manifold. I cut a U bend in half and am welding the bended end to the flange. The pipe will turn and point up beside the blower. I'm thinking I'll weld little pipe stubs to a piece of 3" pipe, then clamp them to the other pipes rather than weld it all out. That way a small variance won't matter and I will be able to clean up the underside where the runners go into the plenum after welding. Sound good or no?
