Project MPXS MAX!

[kenewagner]

It seems strange to me that all these years Eaton has been building roots style blowers that they havent use a diffrent material for the rotors. The alum makes for a fairly light rotor but there are plastics and composites that would make the rotors lighter and make for less rotating weight. In todays world there is plastics for just about everything. Just letting my mind wander a little here

Coming up with a material that would be lighter that could take the stress of 10 to 20k rpms with durability would be quite the engineering project. I like it Ken, if I was only smart enough to figure it out .

Du pont has a product, Zytel HTN a performance polyamide that sounds like it would be right. Very expensive material. The thing is I would assume once a mold was made one could turn them out like hot cakes. But like everything else it requires the start up costs and the technolgy and tooling to make them, so in the long run is is kindof a pipe dream

In my experience machining plastics to a high precision tolerance is a bit of an issue. Keep in mind also, that from Eaton's production perspective, the aluminum rotors are dirt cheap. Also, expansion rates on the rotors that match that of the case is very important and so I think ceramic or plastic rotors would have issues maintaining proper clearance under all operating temperatures.

Just thinking out loud.

 

[SDCoupe]

I would think Eaton has probably looked at alternate materials for their superchargers. My guess is that, like Dave said, the aluminum is dirt cheap and gains from using lighter materials vs cost was prohibitive. We could do some math and see how much weight you would have to shave to gain 1hp at a given number of rmps. I really love doing math...

I think there was an opportunity missed with this build. The one off custom MP inlet systems needs to be compared to a off the shelf MP inlet system. It's been a long theory that the off the shelf inlet plenum was a restriction at 15% OD, this could have been the time to prove it.

Tom do you have any idea what it would cost to do what you are asking? I will put it like this I have more time and money in this project than it would have cost to put a from scratch kenne bell kit on this car. If you can read the data correct my dyno sheets aside from a similar modded car with an 85mm tb mpx w coated rotors at 25% overdrive would be a pretty close approximation to what the increase is with the bigger throttle body, inlet and cold air intake. I don't have the cash to pay for the additional dyno, wrench and hardware it would take to do such a comparison. When the car is back together and right you should be able to see the information plain as day on the detail of my dyno sheets compared to another one with the comination of the regular parts. My rotor pack, belts and methonal wernt right so with all that ironed out the blower should progressively build boost throughout the rpm range like it was supposed to if the setup is right and that is what we are going to look for at 15% overdrive and 25% overdrive and possibly more because will have the right pulleys belts and the methonal system will be working properly when it goes back to the dyno. I apologize if you are disappointed, imagine how I feel.

Dave I have said it before and I'll say it again. You have tons of heart, and you deserve the best man. I don't know of anyone who has endured what you have. The blood sweat, and anguish was much. I was impressed with your results. You are a good friend and I am appreciative of what you have tried to accomplish in such a short time.

Oh yeah and BTW anyone who believes 360+ HP is a failure needs to come back down to planet earth.

 

[SCDan35thANV]

If Charles put it into production I will be a test mule as well if it helps plus I am confident that once you get the kinks worked out you will be very surprised.

Thanks rob but the blower will be at magnum powers tomorrow for a new rotor pack, I have already fixed the pulleys and put my poor damaged radiator back in. All that's left to do is put the new methonal controller and anti siphon sulenoid on and it will be ready for round 2. I wish Dave had a day or two to fly down to Stl in the next month and we could get it done on a Dyno jet that's 10 miles from my house lol.

I am plenty aware of how much money it would cost. I was in your shoes once. Doesn't help that you went with some lesser known vendors for some of your parts, the results of which speak for themselves. I remember when I was trying to use an EEC Tuner when SCT was the new thing. That was a crappy deal. Either way, the custom MP didn't get a fair trial and I hope the community understands that before casting judgement on this potentially new set up for the M90.

I will send you my inlet throttle body and cai in July if you do a before and after and post for shipping both ways lol

I did the rotors with the new coating before they were available, ironically that was the ROOTS of my problem

 

[superdadsc]

Big things are coming! I feel you have a lot left on the table and look forward to it being problem free. That in itself will bring about a sense of relief and pressure.

Remember dyno numbers are just that. I am sure you will be more than happy with the outcome. 390rwhp or 410rwhp. Driving the car and how it performs is what matters a few HP doesn't really matter or at least to me it doesn't. You have built a beautiful example of an SC!

That said I am very excited for you!

It is awsome like it is now but it wasn't right no mater how much power it has or might have it still needs to be right mechanically. The rotors were touching and that's a big no no, that's why I took it apart after seeing some of the coating was off of the rotors when we had the blower off to raise it. No matter What happens to give it a fair shake it has to be right. When its right then we will know and I will be happy no matter what the outcome. For now if you want big power you have to buy a twin screw and pay somone to custom fab all the parts to go with it and that is out of the question for a lot of people. The whole purpose of me doing this was to try to get the m90 as it is to get over 400 rwhp without a lot of tricks, so the parts can be produced and anyone with a super coupe can buy them and know what to expect and I am staying the course til I know for sure.

Tom you will be happy to hear dan has agreed to dyno his car with the mpx standard inlet and 85 and I am goung to send him my inlet tb and cold air intake and he is going to re dyno with it apples for apples which is the ideal situation to see what its made of. Where there's a will there is a way..... And the crowd goes silent

 

[boogeyman]

id have to imagine that its will gain power being as the m90 will be getting to breath the the absolute max aof its abilities aside from having no inlet plenum at all. cant wait to see how it works out and if its gets made by mp

 

[SCDan35thANV]

Plan is to upgrade my injectors to 95lbs since I am only at 60lbs convert to slot maf and do a dyno pull with my new transmission setup with the 85mm throttle body and stock mpx inlet then swap to the new inlet and throttle body to do a second pull to compare numbers. Going to do MS109 pull and possibly even e85 since I have the fuel cell and teflon lines.

Your car will definately pull 400 plus I am excited to see the difference as well because I didn't have the ability to do it that way. The project has taken a turn for the more informative lol. Dan thanks for your help on this I think it will improve the overall outcome of the project however you will def want Charles ro make you one asap as soon as the dyno is finished lol.

Tell me about it lol can't wait! At least it gives me some solid motivation to work harder to make that $
