I can send you a CAD drawing if you would like. Any machine shop can cut the flange from the file. I had a bunch done when I made my custom intake. PM me with your email if you are interested. The flange is the upper to lower intake flange.

A competent muffler shop may be willing to help you, but are you willing to pay them the 20 hours of labour it will take?

If you are making a custom manifold, keeping the progressive throttle design takes a lot more work as the primary ports must be separated from the secondary. This throws most simple plenum designs out the window.

Massive migraine and neck pain. Tends to happen when I but it wasn't all for nothing. After all no pain, no gain right?

Happy to say that after a lot of grief of doing all the research of positioning the SC on top. I've come to the conclusion that it would be cost prohibitive to do it this way as I would have to 1) Use or fab a custom manifold. 2) Fab a plenum.
3) Customize a fuel rail. ETC.... Seeing that it would defeat the purpose of making a system that would more or less bolt, I decided to look a liitle deeper at the original location I intended to put the SC. Besides, It's still cheaper to have AC and heater lines moved or replaced.

Since I was planning on having to fab a custom intake elbow for the SC anyway, Found a better way to fit the blower in that space. Would still have to move some heater and AC lines but I think that would be easier to do than 1, 2 or 3 as I have no machining or welding skill just yet. By the time this project is all said and done I might have to learn how to. For now I'm hoping that a neighbor who was a WWII test pilot and aircraft machinist might lend a hand and maybe teach me how to make a flange for the intake of the SC. Then have some tubing welded on as well as a flange for a Mustang TB so I can fit the SC in the tight space. A local muffler shop is willing to do that.

You're right again NZ, Another Mazda quirk of engineering to use the 2 tiny IC's. this might mean having to go FMIC or Air to H20 IC. Don't know just yet. I'll see about a junkyard FMIC or could the TII tmic be used as an fmic with any effeciency at all? Man, I wish you, rotarygod or Aaron were doing this and I could just get the bolt ons after the R & D was all done. Be much easier that way but then again it wouldn't be as much fun now would it? This gives me a reason to get up before 10am and get my sorry *** in gear.

Signing off for now, Got an aircraft machinist to hunt down.

ErixHvn

Hey thanks for the offer Aaron but for now I think I'm going to try and stick this blower down the side if I can get the right AC lines moved. It would definitely be a lot more cost effective this way.

Still cant get a definite answer from any machinist about the intake elbow on the blower. Turns out there's this guy who used to be a rotorhead himself and was very intrigued about the lysholm but doesn't have the time to help on this proejct. Dang!!! Just my luck. He had the cad/cam machine that could have milled this out of a block of aluminum.

BTW, How many off you guys have the aluminum intake elbow that Higgi@RX7Cz makes? Any chance you kept the plastic one? I could use one of those if anyone has one to spare. I'll buy it off you for a fair price.

Skiles2070

damn son that looks like a hell of a project. I want to SC my fc as well but I wont use that blower type. I want to get that new charger that HKS made for the 350Z or something like that and I will use an intake for mazdatrix, and yeah the plans are only in the planning stage yet but I will asure u that it will happen and it will be hella expensive

ErixHvn

Decided on the Millie SC for it's efficiency. Not that it would make for an easy install but to have the boosted air for as little power loss thru SC drag/ Temp increase such as a centrifugal SC would. I could be wrong but I think some others would agree that the lysholm might just be better matched to the RX's breathing characteristics too. Besides that, Got it off ebay for not a bad price.

The project has slowed down a little bit right about now. Life happens, Then boom, I'm having to find financing to buy a house that needs a lot of fixing but has a large shed I could convert to a garage so I could work on it w/out having to deal w/ FL bugs and heat in the open.

Wish you luck on your project. Maybe when you're done we could compare notes and rides.

ErixHvn

Since last week was pretty hectic trying to secure financing on a new house with a shed to work on my project I hadn't been able to do much on the project but still made some progress.

Found the TB I need at the junkyard off a 300Z, Picked an S5 primary fuel rail to replace the old Rail/Pulse dampener. And might actually have found a better way to attach the SC and keep the existing pulleys in position. Now I just have to find the right size AC compressor clutch w/ a dual pulley. Will have to see if I could match one up to the SC's shaft then maybe, Just maybe, I could have a select switch to run NA or SC'd at will and not have to run 91/92 octane gas all the time considering the current gas prices. Just an idea.... Might not find what I'm looking for but it's worth a try. Otherwise I might just have to have a dual pulley made for the SC. Or learn to make one myself.

BTW, I did get a hold of my neighbor who used to be an aircraft machinist's instructor in WWII, I came to find out just exactly just how much this guy knew about turbos and superchargers. Turns out that in WWII he almost got canned for grounding Col. Paul Tibetts' (Yeah, The Hiroshima, Enola Gay pilot) practice plane at Eglin field in Pensacola coz the planes' turbo had a cracked turbine fin. Turns out Mel (my neighbor) would be happy to teach me how to machine my own flanges and pulley using his milling machine and lathe. Got him all fired up about this project too. Gives him something to do now that he's got nothing but time on his hands.

Now if I can just find the right welder to make the bracket for the SC this project would move forward a lot faster.

'89Vert

This is a great idea for a project. They're have been a few maligned supercharging projects over the last couple of years, so it will be good to see how yours goes. I think what's even better (and has surprised me, honestly) is that even if people don't agree with your idea, they are willing to help. I think that is the true spirit of this board that gets lost so very often in this section. BEST OF LUCK!!!

ErixHvn

You got that right!

to tell the truth you should just go out and buy a gas/wire feed mig welder for a couple hundred bucks, it will be cheaper in the long run and you will have more fun learning how to weld on your own with the self satisfaction aspect of it. i know i love fabbing stuff up, paying someone to do it can cost a bit of money though due to the amount of time it takes to draw out and fabricate things.

ErixHvn

It might wind up that way Karack. Just seems that everyone I've approached for the brackets want an arm and a leg for the job. I know material shouldn't even cost more than $30 bucks but the labor involved is upwards of $300 for most quotes just because it's a mod to a car. Wish there could be some other way around it. Or maybe see about renting a welder and learning on it before trying it out on my car.

I'd hate to be the one responsible for wrecking my own ride that way. Still gotta figure on finding the right kind of studs for the LIM so I can use the same to mount the bracket to it. Seems the kind I can find aren't fit for automotive use. (too soft a material). Anyone ever try to take the studs out the LIM's before? Would the 2 nuts tightened together take them out?

ErixHvn

Just an update on the progress of this project. Bought an SAFC-2 off Slpin a few days ago. Got the vortech FMU that will get a 6:1 rise kit. I think that should be a good place to start for enrichment. I'll be picking up a Bosch bypass valve used on Porsche's, SAAB's and Volvo's for my bypass. Seems to be the easiest to hook up, No mounting bases just a small pipe to the intake at the SC and another to the TB pipe.

Found the right guy to machine the intake and outlet of the SC out of aluminum and intend to hook up some mandrel bent piping w/ a channel for an O-ring where it meets the plates on the SC so i can pivot the pipes to adjust their orientation. Just so I can add an intercooler later on without too much trouble having too many turns in the piping if they wind up pointing in the wrong direction.

The mounting bracket has been the most problematic though. Even if I do find the right guy to do this. I'm having to wonder if mounting the bracket on the 4 LIM/UIM studs while being supported underneath by a plate connected to the studs that hold the ACV would be strong enough. The Camden setup on the LIM just has more mounting area it seems because of it's design. Wonder how they've held up.

Meantime I still haven't got an answer from the AC line fabricator that he's able to move the AC fittings on the passenger side firewall closer in so I can use this location w/out losing the AC. This Millenia SC is just so damn looong it's going to take every last inch of room almost to the firewall to get it to line up to the pulleys up front. I just wont give up my AC's function unless it becomes absolutely impossible. The original intention of keeping this project as close to being a direct bolt on might prove impossible that way but I intend to go the distance to find out.

Still trying to get a pair of 550's and a pair of 680 injectors for a good price? Also need block off plates for the ACV and EGR. Anyone have any to sell? Please PM me.
Thanks

Aw man. You caved in and bought that Stupid Air Fuel Computer. I thought you were going to do it properly the first time instead of doing it again later.

ErixHvn

Sorry, I caved. Just couldn't feel confident enough to tune the MS being that it would be my first time to do any ecu tuning while as there's someone here in town that is familiar w/ the SAFC. I think I'll learn to tune on this first w/ someone looking over my shoulder. Not to worry, It will only be until I get some experience under the belt then go to the MS eventually. I'm going to stage the project as much as possible anyway. Slpin gave me a good deal on the SAFC. Couldn't pass it up.
Anyway, It should give me a better idea of what performance I could get out of the system with a piggyback and then compare it later to the MS. At this point in time it looks like I'll have to do without an FMIC unless I can find one at the junkyard. Or try to find a TMIC to put up front instead.

88IntegraLS

The SAFC is good for learning to tune by the seat of your pants on an NA installation. For a boosted project I'd get something that controls fuel and ignition together. My megasquirt was supposed to do that, but it didn't work out; the megasquirt n spark not working as designed was the last straw that broke the back of my affection for everything rotary.

I'd recommend a haltech when you have the money.

ErixHvn

Looks like Muythaibxr and his team worked the bugs out enough to Plug n' play w/ the S4 NA but I'm not too confident about my ability to tune just yet.
I was hoping you hadn't given up on the project. You were so close to getting the whole thing worked out. I hope you havent done the V8 conversion and go back to the original plan. Even if it winds up a track only vehicle. I'm sure someone would buy it if you did get the MS working to tune ignition and fuel. C'mon man, I know it's a PITA to do something that hasn't been done before but that's the point of a challenge. I'm just not up to the ECU tuning challenge just yet but know this, If you hadn't gone as far as you did I dont think I would have decided to pick up the torch and go for it. 8psi @ 1.5K RPM JUST SOUNDS LIKE SO MUCH FUN.
BTW, How much boost did you have at 4K?

What do you think of my trying to mount the SC to the LIM?UIM manifold studs and the studs for the ACV as a support? Would that be strong enough a mounting and support location you think?

88IntegraLS

I'll never go back! Once you get some REAL cubic inches, there is no way out. The charger setup was totally awesome though. Nothing compares to having an instant source of 8psi on tap, except for maybe an instant 12psi, bwahahaha!

*edit*

I was never able to get to 4k rpm because of the damn megasquirt. My stock ecu wasn't hooked up all the way either so I had no spark advance or something. Anyhow, it would cut out at 2.5-3k rpm, but it sure pulled hard up to that point. Fourth gear felt stronger than third did before.


Theoretically, you should have the same boost at 4k rpm as 1.5k because the lysholm chargers do not leak much and are positive displacement type units. I personally like this type of compressor for that reason, but I'm sure the turbo lag or "foreplay" as the turbo rotards call it can be entertaining. But if I put my foot down, I want the car to respond instantly. That's the whole point of having sports car.

Tofuball

Man, I don't know why you're so angry at the MegaSquirt, Ken and I have got it running on quite a few cars with no issues.

What was up with yours?

ErixHvn

That instant response I get from the Vortec in my 'burb is definitely nice but that particular vehicle is just not suited for spirited driving in . Which is why I'm trying to get the same low end oomph out of the RX7 after getting a little spoiled w/ the V8. Trying to get the low end response without losing topend performance with forced induction is the inherent problem of using a turbo in this setup. IMHO. Although the turbo would definitely win out at the top end I dont need that much top end as the hwy's in my part of FL do not really afford me the possibilty of stretching the legs on the rex and the SC's wide, fat torque curve would be ideal for me.

Dont know if I can get that kind of performance from the 13b w/ a blower but I'm hoping that I placed my bet on the right 'charger.

muythaibxr

yeah, we've gotten several of the megasquirts working no problem...

And there are a number of people who have gotten their megasquirts working great on their own in the megasquirt section of this forum.

When people build their MS units on their own, sometimes they have problems. There is a lot that goes into wiring and assembling these things properly. Any number of things can go wrong, and I do my best to help the DIYers deal with these problems as they come up.

I think my friend bought his unit off of him. I know he got it from someone on the forum who was frustrated with it. We installed it on my friends car and had to make a few simple setting adjustments but it works fine all the way to redline. We puled off a Weber carb and installed the MS instead. The Weber was tuned properly for his engine and it is quite frankly pathetic compared to the MS. I see alot of people get frustrated too early with the MS instead of working the issues out. They are never hard fix. It's usually something that gets overlooked.

ErixHvn

Only reason I didn't go Megasquirt in the first place is the lack of confidence in my own ability tuning not in the MS itself. Were it not for the fact that this will be my first time out on a project this complicated (to me at least) and that I've never done any ecu tuning before I would have gone w/ the PnP MS unit.

But that wont be far behind once I get a little experience w/ the Stupid AF Computer. Maybe someone w/ a PnP and the experience tuning it would be close by and be willing to show me the ropes in person. Tuners familiar w/ the SAFC are just easier to find around the corner right now.

Muy, Tofuball, Do you know of any MS's purchased from you that is coming to FL? Would you mind having them contact me if you do? I'd like to see them tuning it first hand and learn from them if possible.

BTW, Just got the confirmation that I've just acquired the bypass valve I need for the project from ebay. So far all the parts have been under $650 incl. the SAFC2.

Can anyone tell me if the mounting of the SC onto the UIM/LIM studs would be a bad idea? I just dont know how strong the aluminum manifolds and Studs/bolts are to hold up to the tension of the belt pulling on the SC pulley. I'm designing the bracket top go there and be supported below by the studs that used to hold the ACV that will be removed.

88IntegraLS

I still have mine and plan on using it for fuel only on my 302. I had problems during my three attempts to make the LM1815 circuit for VR conditioning of the stock CAS. I fried my ECU twice trying to hook it up. Electronics are not for me.

If there was a full kit with the dual LM1815 circuit already built into the PCB, I probably would have been more successful. But scratch building an electrical circuit from plans and wiring it into an existing microcomputer circuit is over my head, evidently. I'll stick to mechanical fabrication.

I can't remember who we got my friend's MS from. I bought mine as a kit and built it myself. The one we got from a forum member had to have it's soldering completely redone.

I personally don't think any of it is difficult but I guess everyone is different.

I guess the first thing is to get the supercharger mounted on the engine and make sure the concept works. Then go back and tune it well.

s14shockker

SO then what do the lines comming in an out of the bottom do? i am working on making the same s/c work on my 4agze, and am running into the same type of issues, BUT i dont understand why the lines? Lysholm superhcargers are independent and dont need an oil feed like a turbo does. Unless its for running mazda parts that arent installed? or just to add oil? just from the block?

what recirc vavle are you using?
