i know that proper mounting is essential for the health of the engine

Go to StageOneTuning.com and contact James Jones directly. He's the primary contact for hardware that is produced and distributed by FM. He has direct control over inventory and pieces for the MP62 hotside kits.

It's probably out of a General Motors car. They had a love affair with m62's.

actually it;s from mercedes w202 230 kompressor.

they had superchargers with electromagnetic clutch. so with one button i will be able to turn on supercharger... when it's off the car will be N/A.

i guess DIY bracket will be hard to make... it has to be very precise because it will be mounted to the head.

maybe i will buy m45 mounting bracket and will try to convert it somehow...

Don't do it. The M45 bracket is just a triangular piece of metal that mounts to the two central header studs and attaches to the SC. It then has a beam underneath that mounts to the bolt that attaches the Power Steering to the block. You could probably make that yourself, if you think that's all you need. The M45 bracket was cast, and not very strong. A few cases of the brackets cracking and that was on the lighter M45 SCs. The 62 series are quite a bit heavier.

You can't really see it on the MP62 mounting brackets, but on the other side are metal cylinders to mount the bracket on longer, exhaust manifold studs.

I'm actually working on the same supercharger (but as a coldside version), the clutch is a nice feature :-)
Did you already thought about a solution for the missing bypass valve?
I use the bypass block of the M45 Kit...

Beside that, there's a guy on Youtube who finished a hotside project with this charger, 230rwhp....

YouTube - mazda mx5 miata supercharged

Ask him about the production details, he's willing to share...

The sound is simply amazing!

There is no way I would be able to keep sanity with a blower that loud. That's ridiculous.

I know where he he got his intercooler piping design from......

I got a strong advise for you:

Purchase AND READ "Supercharged" by Corky Bell first.

To be honest, you're sounding "a bit" naive as far as supercharging an engine is concerned...

ok, so i've read "supercharged".
there are some people in Poland who used bov instead of bypass valve but now i can see it wasn;t very economical
i think that i will mount a hybrid valve because i want to hear this wsshhhh

now i am thinking of how to make valve not to close during acceleration when the supercharger is off... because the valve is being closed when the vacuum decreases :(

maybe there are somekind of electrical valves that i will be able to open/close with a switch (just like a clutch)

What do you want to hear?

the typical blow off sound?

Forget about that...remember, the charger is BELTDRIVEN which means he pushes air all the time.

this means you wont get a short "Wottsccchhh" when you lift the throttle, but more a "Wooottttttttttttttssssssssssssssssssssssssssccccc ccccccchhhhhhhhhhhhhhh"

which goes on till your rpms are really low or you step on the trottle again

my recommendation:

get the Jackson Racing bypass block -140$- this will give you a flapper style bypass dimilar to the newer Mp62 units... this will bolt to the charger using a simple adspter plate and you can mount your stock throttle body directly on it.

For driving without charger: get a solenoid valve and connect it to the Master brake cylinder after the one way valve...

This is what I did.

hybrid valves as far as i know recirculates most of the air and just the most charged air is blowed off. so if throttle is before supercharger when i close the throttle i guess it should blow off just for a second and then all other air will be recirculated.

solenoid valves that i found has only about 1" of diamtere... i think that it;s not enough... don;t you think?

what do you mean "connect solenoid valve to master brake cylinder"? i thought that i have to connect it to the same switch that clutch is connected to... why connecting valve to brake system??

yYou need a constant vacuum source to keep your bypass valve open if you want to run your engine "unsuperchargered".

so you need a three way solenoid (or a pair of solenoids) to switch between a normal vacuum/boost source for your bypass valve actuator (which closes the bypass valve by going WOT) and a constant vakuum source which leaves the bypass valve open no matter how hard you push the pedal.

The only constant vakuum source in your car ist your brake master cylinder/brake booster (the big black disc-like part under your brake reservoir)

there's a big vakuum line running from the back of your intake manifold across the firewall to this disc. on the very end there is a one way valve integrated.
You have to tee in after it to get a constant vakuum

now is everything clear for me... thanks. at first i thought that this solenoid valve is suppose to be mounted parallel to bypass valve.

i have one more question. what about spark plugs? shall i change it to colder one? how would N/A engine act with such colder spark plugs? engine will be soft charged - about 0,5bar(6-7psi)

another question. do you think that the normal diverter valve like bosch will be good or i should look for m45 valve? is there any difference in build design? because i;ve read somerwhere taht m45 valve has a butterfly inside...

Go for the M45 Bypassblock.

Its got a bigger diameter than those BOVs and the flowing characteristis are MUCH better.

And you need to find a way to mount your throttlebody to the blower anyway, so this is nearly a lug and play solution.

The other way, You'd have to fab an adapterpiege in the same shape of the M45 piece AND buy an BOV so the finished solution is not only better but also cheaper.

the Moss parts number of the bypass block is:
194502062 150$

the bypass block form moss is too expensive for me...

i am wondering that maybe mercedes in her kompressor cars used m45 bypass valves? i know that after about 2002 mercedes used eaton m45 as a supercharger (not m62 as before 2001). do you know if some models of mercedes used such bypasses?
