m62 mounting bracket
do you know if it;s possible to purchase mounting brackets for eaton m62 supercharger for miata nbfl?
maybe you have some scheme so i could produce it by myself? i know that proper mounting is essential for the health of the engine ;) |

the problem is that i need a mounting bracket for M62 not MP62...

How do you suppose Miata related companies have brackets for that??? DIY!!!:fawk: |

So its a used supercharger out of a donor car...Mercedes?

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... |

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. Flyin' Miata : the supercharger kits Studs, Head Bracket Assembly |

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! |

I'm actually working on the same supercharger (but as a coldside version), the clutch is a nice feature :-)

i am wondering if i really need this bypass valve... isn;t BOV enough ?
or maybe in our case bypass valve is ment to do something else then BOV? |
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 :bang: |
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? |
Labor for maschining a proper adapter piece to mount your throttle to the M62 and buing a blowoff valve will be higher than 150$
If you don't have the money to buy these ESSENTIAL parts, maybe you should think again about supercharging at all. You'll also need a bigger clutch, Eninge management, some sort of intercooling, bigger injectors... |
i have a friend who will fabricate this adapter for free. i just don;t want to spend 150$ if i could have it for half the price or even less.
i know about clutch. for engine management i will use FMU, no intercooling and no bigger incjectors because at the beginning i want to have a soft charge max 0,5bar. i will look for used m45 bypass from mercedes. do you think it will be good? |
Sorry, but I don't think, your plans will work out at all.
1. Running the supercharger unsuperchargerd: you need the biggest possible diameter as a bypass with good flow characteristics. The BOVs and recirculating bypasses are NOT big enough. 2. the overall idea: You want to keep the clutch, but you want to use the existing 4-rib belt of the powersteering, don't you? This means you only have a 1.3 :1 pulley ratio, this is way to less to make power. It could even be that there is LESS air moved by the supercharger than what is needed by theengine, meaning you are losing power! So you have three choices: ditch the clutch and get a smaller charger pulley get a crank cover overlay mount an additional crank pulley. But nevertheless, I'm betting that you'll blow your motor during the first 200 miles... Do you plan installing a wideband O2 Sensor? |
so you're saying that bov and recirculating bypasses are not enough but the bypass block from MOSS for 150$ is enough?
i want to mount additional crank pulley to the powersteering pulley but i still don't know what size it should be so the maximal boost was 0,5bar. i think it should have about 15cm diameter... but i will have to calculate more specifically. what is a crank cover overlay? no, i dont plan installin a wideband O2 sensor. well not on the beginning. maybe in the future if i will be changing ecu and going with a bigger boost. |
I would sell the SC you are trying to fab. I tried fabing a A/C bracket once. Screw that. You will spend more money, and months of time, and it will probably never work.
You can piece together a a turbo kit. Way cheaper, and produce some mega power. Just my opinion. |
in Poland it;s possible to fab everything so i will try to do it ;)
RacingGreen you said that in master brake cylidner there is constant vacuum. are sure? because it takes vacuum from inlet manifold. when it;s unsupercharged and WOT i guess the vacuum isn;t enough to keep bypass valve wide open. maybe this one way valve near master brake cylinder keeps constant vacuum even if there is no vacuum in inlet manifold? do you think that bypass from mercedes with m45 eaton isn;t enough? |
I don't know about your answer, but if you want the best vacuum, just split a Y off the intake manifold. Best vacuum there is.
|
Most of the Mercedes compressors use a electronic clutch inside the pulley instead of the bypass valve. This will disengage the pulley from the charger, and stop the charger from creating boost. Maybe you could rig up a vacuum switch to the charger.
