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

[Nexus1155]

So this is funny, Of course everything of mine got deleted from the hack so i am bringing it up again, but wondering more about it. I've never cared to look at how superchargers worked, but i knew the basics. I have some questions on certain issues as well...

So, a user by the name of BoogieQ did a DIY supercharger kit over on ScionLife using an Eaton M62 supercharger(2.5-3.0L Recommendation) Not near our range of 1.5, but he did it, it worked, why not. The exception is with how much power was robbed from the crank to get it to spin enough to make power....

Question in fact is, is the Blitz supercharger using the Eaton M62 or something similar to the size of it, is why the users are getting such minimilistic gains....

Now, here comes into play the Eaton M45(1.5L-2.0L from the mini cooper or Merc Komp, quite tiny as you can see(picture below) The mini with a 1.6L engine can make an upwards of 230hp with a smaller pulley upgrade as i've read. that is only .1l more, so we should not be far behind their gains(with the reasoning that every engine is made differently).

I have seen most superchargers bolt right up to the intake manifold itself, but it does not need to in a sense..all you would need to do is create an outlet from the supercharger that goes into the stock intake manifold, and just reroute some piping while keeping the stock design.

The extremeties of doing this are just piping and brackets to hold the superchargers weight, and of course belts and jargon... nothing at all really...What is stopping people from doing this? Show me some interest peoples!

if you can pull this off that would be incredible. i get eaton parts at a nice proce too. :)

well this might be a doozy, but i want to try to sell my Honda engine to see if i can purchase an M45 supercharger, preferably one from a mini, but they are kind of pricey compared to the bigger ones which is funny

I'm just wondering how much boost i can push without needing a tune. I guess only time will tell until it gets done on here

What else is needed for a supercharger to function correctly? It seems like im missing something, Inlet/Outlet/Belt/Vacuum Line?

umm... what's stopping YOU?

wanna loan me about $600? hahahah

lysholm (whipple) twinscrew headunits are more efficient than roots type blowers.. just FYI..

I had a similar idea for a honda B-series motor. I've pretty much layed it to rest (for now).

You will likely need some bypass valve as well, for when you're running off boost.

[Nexus1155]

AFAIK the blitz kits did not use a bypass valve...but there were thoughts on people adding one as well as an intercooler... i know the twinscrew ones are more effecient, but they are of similar design to the roots, just alot more complicated of a design...I will be posting my Honda Head on craigslist tomorrow to see if i can get any bites and i will let you guys know if i end up buying one...

[Sabretooth]

Hmm Im shocked I never came across this thread in the start.


I would say the best thing is to try and get a parts list from one of the guys who did a Blitz install and see what your needing for everything. It could be possible to compile a list of what ya need hardware wise, then just figure the rest out as you go.

[Nexus1155]

yeah, im about to do that right now and search all the blitz install threads....and i got a couple of nibbles on the engine head so far so this might actually be a plausable project for me...

Should it go....

Intake > MAF > Supecharger > Throttle Body > Intake Manifold?

or

Intake > Supercharger > MAF > Throttle Body > Intake Manifold

im assuming the first one because you need to meter how much air is taken into the supercharger in the first place? but its debatable i guess because you're still monitoring the air after the fact of the supercharger as well

yeah probably why our mini cooper s only got like 19 in the city... but it was whinney and quick!

Interesting thread nexus1155. I'd also consider the rotrex s.c. The install seems so simple.

[Nexus1155]

The Rotrex supercharger is centrifigual?, I like the idea of it, but if i were going to do it that way, i might as well buy a turbo and make a turbo kit... I like the idea of this supercharger is because they are found quite affordable and are in abundance since they come from multiple cars...

The eaton compared to the rotrex would just be needing maybe a stronger mount, and a little more pipe work... but in essence the same... also the eaton you can find smaller pulleys to increase boost... i do not know if the same goes for the rotrex?

Cool beans man. In this times of difficult recession, although my company has assured me my job is "safe", i have seen many friends and people being laid off for restructuring or downsizing their staff. For this reason i am leery about dropping too much money into my car for what i currently deem "luxury" items.
I hope everyone here survives this awful time in american history.

[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...

[Tamago]

unless one has a serious hookup, you will not be seeing prices like the ones above.. change $150 for piping/flange/mounting brackets to about $500 for a more accurate number. and don't forget engine management.

trust me, DIY turbo will cost you less

[Nexus1155]

wow, so technically as the cost of living goes up, pay gets cut and layoffs, and we get screwed even more... very nice

Regardless I cannot use engine management as of now anyways so i'm going to wing it without it until i find a better method than is out there now.....and pricing just depends where you shop until you find a good price...

I think the mounting brackets would have been cheaper than most things, its just a piece of metal that you could possibly make yourself with rough measurements..

If i were to do turbo(Already have two spare K03's), id just rather buy richards kit anyways for it being the easier thing to do, the supercharger kit requires no welding, and the ARC welder i have sucks and spatter will go everywhere... Plus a supercharged yaris just seems right for some reason...

there is indeed something indescribable about the urgency of that whine
