Pre-Hack Repost: DIY Eaton Supercharger, Why Not?

[Nexus1155]

times are getting better, and i think it is a big hype for everyone, which is making it seems worse than it really is currently... Just do your best to get by and try to cut out un-needed items and it will make you feel better... like smoking... if you do smoke... nasty habbit

The cost I will try to estimate as best as i can...
Supercharger - $250
Piping/Flange work - $100(need custom parts made)
Mounting Brackets - $50
Misc Parts/Belt $50

So around $450 for a nice working kit. Honestly the only hard part i see about this kit is lining it up with the pulleys(Anyone know how much room for error in play i can have?) and custom flanges > piping will require some sheetmetal work or atleast for me to fiberglass something durable quickly and make a gasket for it...

No way is it going to come close to being that cheap. You need an entire manifold made, runners with fuel injector bosses, flanges on each end and it looks like the blower snout is not long enough. It will be over $2000 (probably closer to $3000) unless you do everything yourself. On top of all that the blower snout looks too short.

You are better off going with a centrifugal blower or turbo.

I have some experience in designing and building supercharger kits(we designed and built the blower systems for Stillen on the Maxima)-here are a few tips. The belt alignment has to be perfect in every axis or you will throw belts. The blower can blow through the MAF,but it will be much better to draw through the MAF and the throttle body should be mounted in front of the supercharger, not on the manifold in stock configuration. You can run without a bypass valve by air temps will go up significantly under cruise conditions and will use more fuel this way (increased parasitic loses). I doubt the stock MAF will be able to cope with additional airflow from blower, but might work at lower boost levels-we have had good luck in NA applications up to 123 wheel hp so far. Blower needs to be rigidly mounted using mounting plate to engine to keep belt alignment true-this takes some design work. It is a good idea to have blower blow through stock intake as this will help ower compared to blitz set up with short runners. This is not something that can be thrown together, but it can work.

FYI on the MAF, it's the same units used on the Subaru STI.. it'll handle plenty of air flow :)
