Eaton M-62 Supercharger

[yarcli52]

I'm lookin to fabricate an adapter to mount an eaton m-62 supercharger on a turbocharged 1986 laser. Any advisements, warnings, advice, or comments feel free. Thanks

great whine to it ,my buddies ion redline makes 18psi with a 2.79inch pulley,get air to water intercooler too

Make absolutely certain that nothing gets into the blower case that shouldn't be there. And be double sure to put in new lube oil, don't just assume it's oiled.

I'm assuming this is a GM unit from an older Bonneville? Keep it mounted flat, they can't be turned on their side, like the Ecotec version is.

Are you running the eaton with the turbo or changing from turbo to the supercharger? Either way, the m62 wouldn't be my first choice. It doesn't have that much flow potential, and I thought I read it runs out of potential past 250hp??

from what ive seen here there potential for at least 350hp,here some good info on the eaton line of chargers

an m62 is good for at least 350 hp but its pushing its efficiency range, this is what ive seen from personel experience on quite a few supercharged cars using a 4th gen eaton

How much boost should i be running on the turbocharger and supercharger because i don't want to completely demolish my engine.

[frostburner]

first figure out what turbo you will be running with the blower and get maps for both and figure out thier efficiency at x rpm and so on.. no one can tell you what to run on each because you can have a number of different setups, make sure you get the correct map for the generation blower your using and you also have to figure what pulley size you will run on the blower dependant on how its driven on your car through the crank shaft, if you arent too good at math then you shouldnt really just jump in with out knowing the correct ratios on eveerything.. i work with blowers on a daily basis and not every car will put out the same boost using the same blower because of configuration differences..

[yarcli52]

What are some of the ratios i will have to take into my calculations when planning my setup?

[frostburner]

from your crank pulley to blower pulley, take into consideration also if you are going to gear it up or down if it wont be run directly off the crank and what pulley size you will use in between the 2 main pulleys, centerline distance as well from pulley to pulley, also figure out the ratio of rpm from the crank to the actual pulley on the blower by looking at the map to spin it at whichever intended rpm for x amount of boost. theres more if you want to do it CORRECTLY, i mean you could just throw it on with whatever pulley and hope it runs at your intended guessed boost but it wont run the same boost as the car the blower was taken off of because the ratios will be different. once you figure out the boost it puts out on your car if your going that route you will then have to figure by what amount youll have to downsize or upsize the new pulley by to get your intended boost. also take into consideration how many ribs the pulleys are as you will eierth have to match the crank pulley in rib amount or the blower pulley, ive seen from personal experience that 4 rib belts like to slip at higher rpms so a prefered would be at least 6 rib design but i think the cranks on our turbo cars is 4.. also make sure you have the correct rib design on the pulleys so that they match so you dont start shredding belts or lowering thier half life. i could go on but im on lunch lol.. let me know if you have any other questions..

im going to throw up the diagram for my twin turboed supercharged project later on today, itll help show one of the possible ways to route it and engage the system..

I don't know about that, the cobalt ss's run that supercharger and they struggle to approach 300hp.

[frostburner]

diff cars, diff motors, different setups, different cooling methods produce different numbers, an mp62 will produce more power in a v6 than i4 but on a v8 its too small and is being over driven, ive dynoed quite a few supercharged cars ( over 60 ) so i know this from experience..whats your personel experience with supercharged cars might I ask and the usage of an mp45, mp62, mp90 and mp112 eaton blowers on multiple motor setups and applications?.....

saturn ion red line and cobalt ss supercharged have the same motor supercharger and all

[frostburner]

you know there are other cars with bigger motors that have an mp62 ( aftermarket bolt on kits ) putting out 350 hp to the wheels, or are we limiting this to only 4 cyc cars using an mp62?.. and what they are capable of putting out with that blower, i dont think you guys get it.. one blower on one car and motor size will not put out the same exact power as the next unless they are identical motors with identical mods with some deviations, some cars will need less boost to make more power...and some will need to overspin the blower to make more power in turn heating up the air more...
