Project MPXS MAX!

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.

Dave, this is what popped into my mind as well.

One issue is the expansion rates of different materials. Having rotors and the casing from similar materials helps keep the clearances more constant and predictable.

The other issue is the high tolerance required on the rotors themselves. Not all materials can provide the same consistancy with machining operations.

Its also important to keep in mind Eaton is an OEM supplier, so their focus is durability over absolute performance. If something increased performance but decreased durability....it would be a no-go.
 
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:eek:

Happy to hear it. I'm sure Charles would want to see/know these results as well.
 
the supercharger is at Magnum powers hopefully I have it back on the car next week as I need to drive it to the body shop and get the new early model bumper put on for duquoin and detail it. Then I am going to drive it (weather permitting as much as I can that way I break it in more and I will actually be ready for an event ahead of time. This is my first car show as well so we will see how it goes! I am glad Dan threw his hat in the ring as I didn't have the resources to do a full on comparison. He has to change injectors and his maf to use the setup but he said he was going to anyway.
 
Did someone say LAWN?

Saddly so. That was the main topic at Carlisle. Lawn care.

I got the pcv hooked up and got the hood to close. Checked my bypass valve to see if it worked. Looks like its just tuning and exhaust that's needed.
 
MPX with the new rotor pack from Charles and current available MPX inlet,25% overdrive 10 rib setup with heavy duty tensioner springs and thump racing tensioner pulleys, raised top for my front mount, CXRacing front mount intercooler 31x12x4 (have to triple check on the dimensions but it was what Dalke recommended with 2.75 inlet/out according piping, 85mm Throttle body, 3.5 inch intake with 4"x9" filter, 85MM C&L MAF ,Ported big valve heads (1.84/1.56), forged and nitrided crank with Weisco custom pistons with coated skirts and tops, Eagle rods, Yellow Terra Roller Rockers, beehive Springs, Turbo Check Motor Mounts, Hi Volume Melling oil pump, Chrome Moly Pushrods, currently have 60lb. injectors but upgrading to 95lbs since I also have a 22 gallon fuel cell setup with an Areomotive a1000 and all teflon SS lines. Moates Quarterhorse, Innovate Wideband O2, Kooks 2.75 long tubes with vband flanges with custom crossover x-pipe to two Borla ProXS mufflers that turn down in front of my rear tires. Currently installing a 4R70W being built by Alan at DirtyDog a 3800 stall converter, A FreddyBrown performance valvebody, and HCM CompuShiftII controller as well as a new trans cooler with SS lines SFI scatter shield Etc. also trying to fix my leaking methanol lines for my MAF reference dual nozzle snow kit.

Cam specs are here http://www.sccoa.com/forums/attachment.php?attachmentid=51819&d=1328424731

Current Dyno numbers are 380.97hp and 456.76ft/lb TQ on 91 octane since my snow kit was leaking I had to plug it and I would guess around 20degree of timing 20lbs boost and as it was not being logged I just watched my autometer gauge.

Very impressive mod list, and the heads and cam look to be very similar to what I've got. I agree that your car will be a good test platform for the bigger plenum, TB and 4" cold air intake. Looking forward to hearing about the results.

PS: You need to create a Garage page to list all this cool stuff and post some pictures...or if you already have one please add a link to your signature.

I was planning on it I haven't yet since the car has been sitting and getting dirty due to the trans being down. Plus I have to resize my current pictures which I just haven't been able to get around to. I will soon i'll try to do my best this weekend as I want to add my other car to my garage.
 
Are cars are pretty close, your cam has a little more lift than mine does and the lobe separation is a little different mine is 597 597 lift 114 lsa. When you get the slot maf and bigger injectors you should be good to run my setup and see what its made of. My supercharger is already on its way back from magnum powers and I plan to drive the car up to Bellville on Thursday for its first long drive wish me luck lol.
 
update

Well I have a little down time so I made some of the repairs on the issues I had last week. I fixed the dipstick tube problem (wont come out now lol), wired in the anti siphon solenoid to the methanol injection, removed the boost controlled snow controller, ran the wiring for the maf controlled snow controller, sanded down the engine panels and installed the brackets necessary to mount them and mounted the custom stainless piece I had mad to replace the ugly rubber mat thing that goes under the hood latch. Charles also shipped my supercharger back today and it should be here wed morning and I plan to drive the car to work on Thursday up to Scott Airforce base about a 3 hr round trip.

Got the supercharger back on the ca,r fired it up it wouldn't idle so I had to adjust the throttle plate again. Got it out of town about 6 miles and I noticed the heat was climbing heat got to 218 220 and I shut it down off the side of the road. Then it wouldn't re start for a while was acting like it wasn't getting fire and it was cranking slow and backfired a little. Finally restarted and got it back home ???????????
 
The blower is fine it pushed really good boost when I took off but the fans didn't kick on to cool the car down like they ussually do. Then when I shut it down it didn't want to fire back up. I data loged the whole mess so I've got the logs to show what was going on.
 
Got back home tonight and turned the power on to the car and the fan turned on right away? I disconnected the computer, checked thqtr horse connection and all seems ok. The only thing I can even think that may have been wrong with it is I had a bad connection somewhere. I also still have to go get a usb 2.0 connection cable to go from the qtr horse to my computer I used another cable because the one I used on the dyno was bad. It looked as if it loaded the tune ok but that's the only other thing I can think might possibly be wrong. I sent the logs to Dave maybe he will have some sort of answer on it. hopefully everything is up and running mid morning so I can drive it down to the body shop and get the new bumper on and get it detailed for next weekend.
