DIY Supercharger 4G63...(warning lots of photos..)


a few people have requested pictures and or plans regarding my old Supercharger set up on my 4g.. (mods if this thread needs to be moved to correct section please do so..)

this may clear some things up, i have lost alot of detailed photos due to a HD getting currpted but i can answer anyones question in regards to the set up...

the supercharger used was an Eaton M45 from a Mercedes C200 Kompressor

any questions just ask... i would suggest building everything on a spare engine, it makes things alot easier..

warning: i wont be held responsible if you blow your s*#t up



extractors/headers to cope with the boost: (i just recycled my old tri-y's and turned them tuned length)











manifold design:

What's that charger?

A friend of mine is doing something similar with an Eaton M62. Can you tell was it good? Pros and cons?

Thanks!

Pro would be no lag at all, matched with the right cams it feels and pulls like a bigger engine as well as having a wider power band.. also scaring the s*#t out of big block owners when they hear the whine under a mitsu bonnet...

Con would be that sometimes Superchargers are more expensive then a turbo in regards to its parts and replacements, and tuning.. some tuners freak when they see a supercharged on a worked 4cyl....

other wise same as turbo... but without the kick in the back of the head..

Thanks for the info. I have more questions

How about hp loss to spin the charger? What is the brand/model of the supercharger? What cams did you use? Any dyno numbers?

loose around 5-10%ish power to spin the charger (depending on the charger design wise, can be more or less), more torque, the instant boost makes up alot of the lost power.. add a sandwich plate cooler between the supercharger and the manifold and you can make alot more of that lost power back.....

its in the first post... Eaton M45 from a Merc C200/180 Kompressor

and no i didnt get enough time to dyno and tune properly before the supercharger died racing someone in the mountains..... (it was a 2nd hand unit couldnt expect much)

Very interesting! Good job on building it! That takes a lot of desire and ingenuity, especially since its so easy just to slap a turbo on.

Very cool first time i've seen that. This should be moved to custom fabrication. How much power are you making at 8psi?

i'd say it was making an easy 150kw at the front wheels before the S/C died..

when it did hit the dyno i got 57kw at 38% before my fuel system said no more (n/a ECU and injectors).... slapped on the VR4 ecu and injectors and she was back to more power but pinged slightly due to the maps being off....

cheers for the comments guys....

i would love more people to give the Supercharged way a go, they sound awesome and can still keep up with the turbos and you dont normally hear a supercharger whine on a ### car...

It is a very interesting build and perhaps we(well 1g owners) could use the exhaust from a non turbo 4g that would eliminate the exhaust fab. As far as the intake that is another story.

How was it getting the belt for the s/c as well as making those belt tensioner mounts?
