3.8l m62 supercharger on 2.8l 60* v6

[mikeal6031]

Hey I thought I would post up my project... it may help to show people the amount of machining work needed to make this possible... which to me wasn't that much Haha but here you go, enjoy

There is the work I did to the intake manifold

There is a look of the adapter plate (not finished in picture)

There is a picture of basically what it will look like minus the intake plumbing

That thing looks massive for that motor lol. Lots of machining I see. I guess if you have the sources and the know-how, the entire build could be all junkyard parts... I'd like to see it run when you are done!

I forgot about this, any progress mikeal6031?

I haven't been able to do much with it with workin two jobs and college but I switched vehicles im putting it on because my 3.1 Rs has a serpentine belt which will be easier to work with than the 4 rib and v belt that I have on my 86 base, the onlything I really have to do is drill 8 holes in the adapter plate to mount it to the intake, and then I just have go bolt it up and put a belt on it. But then the tuning aspect will come in, I have 350 v8 injectors which should work well, I have to monitor the afrs. With the wide band to make sure its not goin lean but im sure im goin to hit some bumps in tuning it.... I've learned nothing ever is as easy as it sounds Haha but ill try to get a runnin video up on you tube when I get it done

Last night i took some time to remove the stock manifold on my RS and put the new manifold in

stock one

there is the new manifold in

the adapter plate just got drilled for bolts


there is what the supercharger looks like on the plate

That is what will be sticking out of the hood
The output should be 240-300 hp depending on the camshaft and the intercooler

W00T! I would be very interested in a video when you can get it up and running, very cool.

How are you planning on getting the TB to work?

[mikeal6031]

I figured out the intake system it looks a little weird but it kinda adds to the aggressive stance

there is how i got over the firewall


and there is where it will go back under the hood
I just have to do some more milling on the adapter plate and get two idler pulleys and then put my injectors in and hope i don't blow it up

[mikeal6031]

some more progress on the intake manifold

there is the intake for the m62 (going to need some cleaning)

there is the plate i made to bolt to the super

The plate attached to the super... i need to make another one to seal off the EGR to the blower



and then the tubbing 2.5" should be able to handle the 600cfm the blower will be drawing in (hopefully)
one thing i found is that the drive pulley on the RS puts the bet ratio to max the supercharger out when the engine is at 6250 rpms so the blower will be producing more boost at all the lower rpms than when i had planned this all out for my base coupe haha 12-16 psi should be the result at 6250 haha

Personally I don't think that is the best idea.

With the parts at hand I guess you are doing okay.

I would have turned the supercharger around 180 degrees, taken the snout from a 98-03 Benz SLK C230 (link) and ran a dummy shaft back to the main belt. This seems like a good bit of fab work, but your TB will be on the proper side and you wont have to mess around with using crush bent exhaust tubing for an intake...
