Hello all. I've been playing with the idea of procharging my C63 for a while now and have decided to become more serious about making the idea into a reality. There are a few issues that immediately come to mind; firstly, where would the compressor unit be mounted? I decided that the most simple (and cool) way to solve this issue would be to have a precisely fitted hole cut in the hood in order to allow the compressor unit to sit (roughly) halfway submerged in the engine bay and halfway out of the hood of the car. A custom CNC machined compressor mount would need to be made, which i have spoken with Eurocharged about. Secondly, a custom series of pipes would need to be fabricated in order to pair the outlet of the compressor unit to the inlet of the front-mount intercooler, and from the outlet of the intercooler to the throttle body. I figure the appropriate tune for the setup would be similar to the tune for a supercharged m156 motor, with a possible deviation at lower rpms to accommodate for the brief period of time where the air in the intercooler/intake manifold is building pressure before being fed into the motor (I suspect the initial boost curve in a procharger setup to be slightly different from a top-mounted supercharger setup). I believe that these aspects of the build will be the most challenging. But overall it seems quite straightforward. I'm reaching out to this community looking for any kind of advice/ideas/criticism on the idea before I jump right into it. Thank you in advance!

I like where your head's at

Before you start hacking up your car... Why not just do a proven S/C setup? I'd rather drive a fast clean car down the street than a fast car with a big hole in the hood. I can see it making sense on an American muscle car.

My fear is you'll get just beyond that point of no return and want to return.

I know that the power potential of a procharged M156 is greater than that of a weistec or magnuson supercharged kit. They run far cooler and require less driving force to build the same amount of boost. The cost of a procharger is also much less than other blower units, and they have displayed a lower rate of failure. Also, largely, I would really like to do a procharger simply because it hasn't been done before.

CarHopper

I was going to ask about tranny, but I see you already have a Renntech one in there.

The only other issue is your bottom end. I would just make sure I had another car to drive for a while just in case haha.

I'm just an advocate for not chopping up c63's and doing a bunch of ebay builds. Not saying your build is an ebay build, but you get what I mean... Just clean builds.

Good luck!

Why not just buy a C7?

Yuuuuuge amount of respect for this. Yuge.

Blake_von_Texas

Because I have no desire to own a C7. I have a desire for the same German luxury 4-door that I have now, but with a couple hundred extra horsepower.

Many thanks. Emotional support is appreciated while trekking through this unexplored C63 territory

I always think that this kind of stuff is like NASCAR or F1. Trickle down technology, and the stuff you learn here will help us all at some point Im sure.
***** and bills aren't enough, you gotta have some brilliance too, tho the less brilliance you have the more bills you're gonna spend lol.

I'm attempting to design the system myself just by reflecting proven designs and following basic principles. The hardware cost of a procharger system is significantly less than the cost of say a Weistec blower kit. I'm shooting for the overall project to be both affordable and of high quality/power/drivability.

CarHopper

Taking a personal dive at this will not end up being an affordable option. You'll be tackling something that has not been done before. I wouldn't be surprised if you ended up at S/C cost and maybe more by the end.

Definitely would be a cool project though.

Blake_von_Texas

I'm curious to see how it begins to play out with cost of fabrication, tuning, etc.

I run a procharger on my 67 camaro. I am very familar with the unit and I do like it, but not for the C63. I would absolutely not run it for the car. It does better on higher rpm motors. I would not play with it.

You have to completely remap the engine bay to put this thing on. Plus all your airflow intake would have to change. They don't make a package for it because you probably can't fit it without major mods and it won't be any better than the kits you can buy that are plug and play.

Did You think about a custom programmer? You will need one. You will be a gunnipig and that will be very costly. I can not advise against this course of action any more because it will cost you over 3 times the money and time than the proven built systems. Don't do it!!!

CarHopper

That's what Im saying.... The final cost is going to end up being banananananasssssss

Mazspeed

I hate to say it. It absolutely will be anything but affordable.

I'm definitely interested in seeing this. I've used Vortech's before "not on mercedes" my friend has a vortech on his M5. I agree it would be better than a top mount sc.
Personally i think going turbo would be allot easier.

callmiro

Your attempt will not be affordable. The affordability of the blower will not cut down on the high cost of engineering this to work.

You pay alot for a Kleeman or Weistec because they are bolt on and engineered solutions.

You should probably think about the Magnuson kit if cost is your goal.

chrisridebike8

I don't think his ulimate goal is to be cost effective. I think he wants to be different and innovative and do the R&D so that his efforts ultimately result in what would be an affordable kit for the rest of us. I say good luck, sir. I'm looking forward to your progress.

durranic

ooo I'm excited to see someone else going out of the norm!

glennhl

I'd much rather have a centrifugal blower than a roots type, they are more efficient and will make more power. However, I do not want to cut a hole in my hood so this option won't work for me. But I applaud you for tackling this project.

And I don't agree with everyone that it will cost more. If you can fabricate your own brackets, then I don't see why it shouldn't be less cost than the roots type blowers.

mthis

Subed. GL with build.

Mazspeed

It's not just brackets, it's programming the ECU with a custom tune due to the different ramp up of this blower as to the other blowers that were developed with software and hardware combined.
There is just no room to run intercooling piping, custom brackets from the crank, and at least 8 feet of 2 1/2 inch tubing with 45's and 90 degree bends from the Procharger to the intercooler and into the intake manifold, which would all have to be custom.


But to me, this is a cake walk till you program and tune which will be the biggest nightmare of the entire project.


I spent 15k on the parts and install and spent another 18k on different injectors, knock sensors, and electronic tuning and never had to deal with the electronics of the Mercedes, and I had a ton more workable room in a 67 Camaro.


There is a reason that these places like Renntech and Weistec don't do this. I give the OP credit to want to do this, but this will be a nightmare for a shop like them to do it. If I was the OP I would call one of these shops and pick their brain and see if this is doable for a decent price.
