It's doing what the dyno says, you can feel the dip after 62/6500. It doesn't want to clime to redline like others I have driven.
I have a scanlizer or whatever Hymee calls it. Just the last time I tried it we didn't have a laptop that worked. Dana just got a brand new one, just hasn't been delivered yet. I should be able to do this week.

I agree that the engine as is will be allright with the existing comp. Those blow ups were pretty dramatic. I saw the rotors out of the engine that blew and RB took apart, they look nothing like that. Pistons or rotors, abnormal combustion is violent. I have somewhere a pin from my own small block that is just ever so bent. I'm talking an aftermarket super pin here. Looking at that part and thinking of it bending you get the picture.

let's hook a cable up to the throttle plate and see what it does

Richard how bout an update for the s2ki.com guys they are getting restless.

I think Mazda has had plenty of chances to fix your 8. Its time to start talking to them about the lemon law or better yet have your lawyer talk to Mazda. That should get them off of their rear end and do something about the problem. :D

I am sure some on here on the board is a lawyer and is willing to donate some of there time to get this project rolling again.

I just read in another thread that someone was having problems after 6000 rpms because of burnt coils. Have they been checked already?

BrazilianRX8

hi richard,

i am wondering if you have the mecanical part of the kit together already.
i would be interested in setting it up over here....
i already have a ecu solution that would work for me

Richard Paul

There are no parts available for sale now.
I am interested in your ECU solution though. It is my intent to add a nozzle to the inlet of the SC for the excess air. Do you have any info on your unit?

It is targeted for the end of the month to have the SC installed in my car. No answer to the Fuel problem yet. Stand alon units are way to high priced to be sold with the kit, it raises the price out of the market.

Hope is for a system ala RotaryGod to surface. If we have to we will build our own. That will delay the marketing of the kit but how can I supply a control that costs almost same as the compressor? Someone is making to much money.

Photic

He might be talking about the one on this thread. It's a pretty hot thread at the moment.
They have a pretty impressive video on the manufacturers site too.

<---- Still patiently waiting.
Too bad your 8 isn't up to snuff just just yet. Should've picked up a titanium - I heard they're the best out of the box .
Honestly, I hope you get that fixed soon. I would really like to see what your SC can do with a comprehensive fuel/spark controller (like perhaps the Megasquirt).

If you need east coast testing let me know. :D

Not. That one is of no interest to me at that price. The one this guy has is a unichip or something like that. It has an extra nozzle in the intake manifold.

deppenma

Richard have you considered an Allen Bradley PLC controller. :lightblb:
It is very simple to program using the latter logic program that is supplied with the chip.
5 lines of code is all it would take.


A simple equation could be programmed into the chip to add an increasing amount of fuel as the voltage from a pressure sensor rises.

unichip is quite expensive to richard. on the order of a grand

Where do I find this product?

rotarygod

That's a neat idea but we still require altering the ignition timing somehow.

I have a feeling that Charlie is desperately trying to get this project to speed up. lol Keep up the great work Richard. We have faith in you.

Richard check your emails. also the sales@axialflow.com address from your website bounced my email back. ougth to have that checked

The PLC is a good idea but I have some questions. First is it fast enough? Then can it take the automotive usage. Meaning vibration and heat. It seems to me that mounting it underhood is out of the question. Don't think these were designed for that.

Just did some math on these and it would be just about on the minimum or speed. That would be worth a try but the size and durability are the drawbacks. They are rather bulky. Not really elegant for our useage. We have used them on some automated machines that my partner designed and built. They are a snap to program, anyone can do it.

We think it would be a good thing to use for the engine dyno. Should that need ever come up. Still a good thought and I'll keep it in mind.

Richard Paul

iTrader: (5)

I don't know how to get that damn thing to work. I own it and have done some of the whatever but it just doesn't come up. It's me or the computer. It has a lot of virus. It is so slow now that I can't even draw anything with it. Good thing I don't have any design projects right now. Just that I will soon. I think I better take it somewhere.

PCdoubleE

I have done work with AB PLCs on Coast Guard and Navy Vessels. They have normal industrial temp ratings of 65 deg C and seem to handle the marine environment well (lots of shock/vibration, think big diesel engine 2 ft away). I agree that they are close to being too slow. As an advantage, you could come up with a run-time user interface for a PC to sell as an extra :D.

A better idea might be an off the shelf FPLD board. Those have become very fast and relatively cheep lately. You can even get them with on-chip A/D and D/A so you don't have to worry about the conversion of the transducer signals off-chip. Also easy to program.

Sorry if this has been suggested before (did a search for FPLD - got nothing).

TexasKyle

While the Slick 500 is a nice piece from AB, the software to progam it is over $1000. That is just to write/edit/view the ladder program. This would still not give the end user of the SC any sort of control, monitoring or ability to change anything. Plus, in order to use the PLC based system, you need the CPU and an input/output module and probably a scanner module as well. Just these three things, plus the rack they would have to go in, make it a less than attractive option. Good idea though...I love PLC based systems. Have a ton of them at work.

RX8-TX

Well...there is always the option of going with a PIC based solution. They have A/D D/A. amplifiers and more intergreated on the same packages, but I don't know if they'd fit the right respone times required.

rotarenvy

I'd like to see you fit your SC and tune it with the new plug-in EMS that’s being talked about at the moment. I realise it is not where your 'kit' development is heading but It would show the SC's full potential. You could potentially start selling SC units to those people that would probably ditch your fuelling method anyway.

Your chosen method of fuelling is probably going to be a compromise for various reasons and it will also probably be unsuited to .au conditions and factory 'tune'. For these reasons I would prefer to buy only the hardware (SC and mounting kit) and take it to a professional rotary shop to tune it with the plug-in EMS or motec. This makes lots of sense since some form of custom tuning is inevitable.

Richard Paul

Number one, who says that this EMS will have better potential then what I intend to do. Since no one but myself has experience tuning these type superchargers why would you assume that I don't know more then they do. I also don't think there will be many who toss the factory developed system to have some guy in a garage build them a one off system. Stated that way does it sound the right thing to do?

Since when do I compromise? Just ask my ex wife. The system that I supply will be as good as it can get for any reasonable usage. I don't want to sound cocky about it but I spent 13 years tuning these things on my own Superflow engine dyno. In house there were no limits on how much testing I could do. I didn't pay for dyno time by the hour or have to go to someone elses shop. On the otherside of the wall was an engine building clean room. I learned a lot about what works and what not to bother with.

I know there will always be someone who knows more then I do about these things and they will redo things and if history has any validity they will destroy their engine. I have storys of it with my old blowers. However the best installations were done by people who admited they didn't know everything and followed the directions.

My problem of offering the unit bare is that when they blow their engine I will get badmouthed for it. It will always be the SC's fault. Therefore I will sell the kit with a locked controller. You think that is big brother don't you? Try looking at it from my point of veiw, It will always be the blowers fault if something goes wrong. I have to try and protect the reputation of the product.

This is not to say I'm closed off to other systems, we will continue to look for better ways to build things. But the thing about my idea is that the car runs just as it did before with all the stock sytems intact. No problems from cels. My fueling and spark changes only start to work when the manifold pressure goes posative. No EPA cycles use full throttle so nothing changes in any tests that governments do. I will be able to get CAFE exemption without a doubt because it will be run on the stock ECU.

I will not go into my theorys on homagiazation because it is writen at the begining of this thread. If intime there is someone who sounds like they know what they are doing and we have no personality conflicts (one of the requirments might be harder then the other, guess which?) I will help them develop whatever they want.

Gotta go back and drink some more "whine" now. Hope I got your questions answered.
