eaton m62 supercharger
 
i see eaton makes a m62 supercharger for a Mercedes Benz that has a shorter configuration. it looks like it may fit a lot better than the m90. any opinions on the use of the m62? i have a pic but cannot figure out how to post it. can someone tell me how to post a pic on here?

Luke_Tech 06-15-04 12:05 PM

email me the pic and i can post it for ya. luke_amstutz@mchsi.com

You should not notice any difference between the M62 and the M90 unless you are going to try to go higher than 275HP because the M62 is limited to around 460CFM but the M90 is limited to around 540CFM.

According to Eaton's graphs, it looks like the M62 is slightly less efficient at the same pressure and CFM than the M92 but I'd bet it's not enough to notice.

would you know if the eaton m62 supercharger in the mercedes slk 230 turns in the proper direction to use it for an rx-7 mod?
thanks

I have no clue but if the engine turns the same way then the SC turns the same way.

I don't pay attention but the only engine that I regularly hear about turning in the opposite direction is Honda.

It's almost easier to mount a SC if the engine turns the wrong way because you can use a go-kart axle and second belt then you are free to mount the SC almost anywhere.

MODS: Any chance of cleaning this mess up. Aaron called it on page 6 but was off by like 10 pages. This thread is informative, and yet full of crap. I also think you should cut individuals post count by 5 for every dumb arse post asking for the 1000th time for info on the brackets. By the way I volunteer this post to be the first one killed and my post count penalized.

ZBrown, I will be happy to do the write-up for you if you’re interested. I can give you a number to call collect, I will take the info down, send it to you for proofing. After the write-up is done I will add pics, put into adobe and send back to you so you can sell. You should charge a few of these annoying guys triple for all the arguning and gushing.

I say to close this thread to all except z and the mods. 20 pages – come on guys, this is a technical forum!

White_FC 06-16-04 08:41 PM

Your going to try and _sell_ a PDF file that is a write up for an amature project of slapping an old supercharger on a 13b?

:rlaugh:

Sorry....

Mr. Gadget 06-16-04 08:44 PM

no its more to shut the whiners up = persnally I will stick with converting my vert to a turbo. just trying to do the kid a favor :P

zbrown no longer has internet access. If you will remember, he's still in high school and only had access to the net while at school. If anyone wants to get info from him they're going to have to drive to where he lives and talk to him.

Hopefully someone actually will!!

That is the unit that I have been eyeing. Oooo I would love to do a write up on fabbing in that thing. U guys just don't realize how easy this actually is. Can't you see that all you need to do is make:

Brackets
Pipes
Pulleys
Fuel Pump change
SAFC installation
FMIC installation
Water Injection
FMU installation
Throttle body and AFM relocation
and perhaps install some TII injectors
Custom intake plenum chamber or use the TII UIM with some modification.
And then dyno tuning, and that's all there is to it.

Seriously, if u need a write up, it would be best to wait for someone to just offer a kit or set of plans, because the tuning of any aftermarket forced induction system is not for beginners, and you will lose your engine if the thing goes lean on you under boost. Hooking up the blower is about 20% of the process to doing it in a way that will make the engine last and make some respectable power. The Atkins kit puts out 185 crank horsepower because it has no intercooling. Any normal streetport six port 13b with a few intelligent mods can exceed 185 crank horsepower for a lot less than $3k.

Why water injection if you're going to have FMIC?

Luke_Tech 06-16-04 09:20 PM

what exactly is water injection?

BDoty311 06-16-04 09:53 PM

Because its safer, and you can run more boost.

The cooler the intake air, the better. Cooler air is more dense, with denser air you can run more fuel with the air. More air and fuel in the right mixture will make more power.

Why have shocks if you've got springs? Because they do different things.

An IC cools the air and water injection does too but more importantly, water injection also lenghthens the combustion event and also chemically interacts with combustion (water is not completely inert inside the combustion chamber).

Either one is good, both is better.

^^thats what i want to do.

a whipple w/ a fmic...


for repectable(15-20) boost you need bigger injectors, a standalone, and a few sessions on the dyno.

Just think about having instant boost all the way to redline... too cool!

88IntegraLS 06-17-04 11:03 PM

Sweet. Finally someone understands the whys of water injection. If it's good enough for the supercharged V12 P51 Mustang engine, it's good enough for my wankel.

HAILERS 06-18-04 01:13 PM

Has anyone measured the intake air temps after the supercharger? I mean someone who has actually done this project. Maybe they are a lot lower than I have been imagining....probably are. Just curious (trying my best to get this thread over 21pages):D

You forgot this.


BUMP!


Ha!


On a more serious note, can the M90's be mounted in any 360 degree variation? Or must they specifically be in the one direction when mounted?

HAILERS 06-18-04 01:25 PM

Oh, darn. He answered that on page 16. Disregard. Just 200 degrees at the inlet. Sorry to take up space and make this thread longer than it should be. Penalize me five posts, please. Read and answer the post just above this one, please.

A series four turboii intake will fit on a six port. What you have to do is get your Dremel Motor out with a barrel grinder on the end along with a six port intake gasket for a pattern. Put the gasket on the turbo ii intake manifold, scribe a line around the holes......then remove the gasket and grind for approx two hours (only takes about four to five replacement pads) to remove the excess material in the turboii intake. Then buy a turboii throttle body off Ebay to go with it........and while your at it buy a tubo and turbo exaust manifold off Ebay and skip the supercharger all together.:D Ahhhhh...I didn't say that, did I? Not nearly as much fun as putting the supercharger on and getting that low down torque.;)

SonicRaT 06-18-04 02:32 PM

With a stock turbo it'll spool by about 2500rpm, how much lower do you want your torque HAILERS? :)

As already established in this thread TWICE, you can mount it anywhere you can run a belt; upside-down, sideways and/or backwards.
