SHO-Z Posted September 4, 2004 Share Posted September 4, 2004 Well I just bought a Mercedes Benz SLK230 Eaton M62 Supercharger for my 260Z off of ebay for $200, oh well got to spend the money on something. The project plan is to use forced induction on round top SU carbs. The neat thing with this set up is the “Kompressor†has a electric clutch like an air conditioner and can be turned off when I want to run around on regular fuel. Still have a lot of designing and research to do to make things work. Would like around 10 PSI of boost when finished. Quote Link to comment Share on other sites More sharing options...
tannji Posted September 4, 2004 Share Posted September 4, 2004 Finally!!! We have needed a "MADMAX" Z..... and all the MadMax doubters can shut up about Mel using a switch to turn on his SC... lol Quote Link to comment Share on other sites More sharing options...
SHO-Z Posted September 5, 2004 Author Share Posted September 5, 2004 I found this picture of a eaton supercharger in a TR6 with SU carb it does look nice. I might have to go with this design. [/img] Quote Link to comment Share on other sites More sharing options...
slownrusty Posted September 5, 2004 Share Posted September 5, 2004 I had a similar set-up when I supercharged my 1987 RWD Corolla GT-S. I used the Toyota derived Eaton supecharger . This supercharger also had an electric clutch but was driven off the TPS that was then linked back to a relay and then the car's ECU and was only engaged when the accelerator was at a certain position (naturally in the accelerating position). I had a custom crank and supercharger pulley machined for me and ran 14psi all day long, the car was incredible and the list of victims is longer than my arm. I miss that car..... Here is a pic of my supercharged set-up, I believe I was one of the first sets of enthusiasts in the U.S to attempt this conversion, while keeping all the factory EFI, and emissions friendly and 30mpg all day long. Yasin Good luck!! Would love to hear the progress of your install. Yasin Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted September 5, 2004 Share Posted September 5, 2004 I dunno what SHO-Z is planning on doing exactly, but forced induction and SU"s has been tried quite a few times and usually ends up being more trouble than it's worth. For one, don't even think of running that with only one SU... someone here did try running a single SU, suck thru turbo system and had issues with the SU not being able to keep up with fuel demands. Secondly, I've seen pull thru dual SU turbo setups, and the major complaint there is that they are just a PITA to get tuned and to keep them in tune. Stock SU's were pretty close to their limit feeding a stock 2.4L 6 cylinder. And before Norm comes in to yell at me yes they can be made to run even 2.9 liters or more, and do it well with simple mods like running richer needles and such, but I think asking them to keep up with forced induction on top of a 2.8L motor may just be asking too much. Just something to consider.... Quote Link to comment Share on other sites More sharing options...
tannji Posted September 5, 2004 Share Posted September 5, 2004 LOVE that Corolla! I would like to see that done in a Z for sure, but I think some sort of EFI would be preferable to the SU's as well. Quote Link to comment Share on other sites More sharing options...
dot Posted September 5, 2004 Share Posted September 5, 2004 Wouldn't fuel injection deal with the 'on and off' loads more efficiently? Quote Link to comment Share on other sites More sharing options...
SHO-Z Posted September 5, 2004 Author Share Posted September 5, 2004 As I said that I am still in the design portion of the project. I have to weigh the options of using a ZX turbo FI set up against carb. After sleeping on it the SU is out. Might have to use some type of 4 brl or stacked dual side drafts. It might be fun to set it up first with the carb see how it works and then try the FI. There is still a lot of research and planning to do. I still have to figure out how this set up will affect the vacuum system, ignition, intake manifold, general layout and all. But this is part of the fun! Any and all information and comments are appreciated Quote Link to comment Share on other sites More sharing options...
Guest 2slo4u Posted September 5, 2004 Share Posted September 5, 2004 Wow! That supercharged corolla and zx really kick arse! I like the injector setup on the gold engine. That is really creative and looks organized. Very close to the side and the hood, though? Wish I could check out either of those cars, I bet they really scream!

RacnJsn95 Posted September 5, 2004 Share Posted September 5, 2004 How exactly does that SC work? I've never seen one that worked off an electric clutch. I've always wanted to come up with a "Mad Max" on/off system ever since I saw it when I was little! This would be a neat setup for my 620 pickup!

SHO-Z Posted September 5, 2004 Author Share Posted September 5, 2004 Most of the eaton supercharger used by GM and Ford use a bypass around the supercharger when the power is not needed. Mercedes use a electic clutch, like and an air conditioner compressor in a car. In that it is not turning at the time reduces wear and less hp drag. The air passes throuh the rotors on the supercharger. Quote Link to comment Share on other sites More sharing options...
RacnJsn95 Posted September 5, 2004 Share Posted September 5, 2004 Seems like it would be more drag passing the air through the SC while it wasn't spinning. Still a very interesting set up. I think I am definitely going to pick one up for my 620, it could be fun! Quote Link to comment Share on other sites More sharing options...

I think I am definitely going to pick one up for my 620, it could be fun! The rotors still spin when the clutch is disengaged. It is just that they are driven by the vacuum of the motor. Old style super charged cars had no problem getting home with a blown belt. It is just a little harder on the fuel economy. Quote Link to comment Share on other sites More sharing options...
RacnJsn95 Posted September 5, 2004 Share Posted September 5, 2004 That is very interesting... Sounds like that would be quite the hot setup if you could get everything mounted up. I'll definitely be picking one of those up as soon as I get some $$ laying around. Quote Link to comment Share on other sites More sharing options...
Guest eric-z Posted September 8, 2004 Share Posted September 8, 2004 I have seen some V8 cars running both fuel injection and a carb... I was just wondering if you all think that this might be useable in this application by using the SU carb to run the car when off the supercharger and when turned on then the efi is also turned on to add fuel?

Tony D Posted September 8, 2004 Share Posted September 8, 2004 Eric, Chances are they were running a four-barrel Air-Door which looks just like a carburettor. I would bet they are EFI cars. My 260 Project looks something like that. Two 550CC injectors in the float bowls of the carburettors, hidden wiring, hidden sensors.... Muahahaha... Now even Moon Equipment is selling Stromberg Replicas so o9lder Flathead Fords can have two injectors per "throttle body" and EFI, but LOOK like old-school Triple or Quad Strombergs complete with the littel "ship vent" stacks... If in doubt, check it out. Some guys are very adept at cultivating a look. A non-EFI look. Quote Link to comment Share on other sites More sharing options...
Guest eric-z Posted September 8, 2004 Share Posted September 8, 2004 huh... yeah I didn't know that... now I feel stupid... oh well, you have to learn somehow Quote Link to comment Share on other sites More sharing options...
Tony D Posted September 8, 2004 Share Posted September 8, 2004 DON'T! I have seen guys with 40 years on flatheads walk by a roadster at teh GoodGuys show, not giving the engine a second look, unitl I say something like "Hey! That's EFI!" Usually it's "No, those are strombergs, son." And then you ask what the little black switch is on one of the throttle plates, and BOY, the sunglasses come off, people stoop, scrutinize, and "I'll be damned" usually gets uttered a few times. Unless you look closely, you can miss it. Unfamiliarity is not stupidity. We have all been there. Quote Link to comment Share on other sites More sharing options...
