Well it looks like I have some shop time and we will mount and run the dash 2 blower tomorow.
There is something I need to point out, other companys are trying to develop kits for the 8. They are all taking an existing compressor and making the brackets and such to put it in the rx 8.

On the other hand I am developing the compressor to start with. This is the hard part. We are building this compressor to match the 8 and not as a universal componant to sell to kit builders of all sorts.

I am not trying toot my horn just want you guys to know why it is taking so long. In the mean time we have learned a lot about the Mazda electronics. Not to claim we have all the answers just that we are learning. Now don't go off getting pissed because we don't tell everything we find. If these things cost time and money we need to keep them to ourselves.

I will keep you posted on how the testing is going.

 

Hopefully your efforts will be rewarded , once your project is completed and tested and the $$$$$$$ start rolling in . :D

PS .I for one appreciate that your compressor is built and designed for the RX8 and not a one size fits all mass produced unit.

cheers

Please excuse me for not watning to wade through 40+ pages. I have been following this thread since the start.

My question is in regards to both your charger for the 8 and any charger for any car. Is a standalone required? I just want to make sure before I jump in one a few projects. If running low psi, it seems to me for the 8 you wouldn't.

 

Richard,
Did we mention you rule?

Lol.

 

As with any form of forced induction, you are not just going to be able to slap it on and get more power with no ecu retuning. Some form of retuning for the ecu is required. Whether Richard offers a solution for this or if he will just recommend an aftermarket unit such as the Canzoomer or Ric Shaw (my personal recommendation) is still unknown. My guess is that if this will be offered as a kit, it will have to deal with this in some fashion.

 

RG: just the fuel and ignition would have to be delt with correct?
On the rx7club board someone I believe had SC a FC3S for very cheap, which made me wonder if he had a standalone ecu.

 

Without fuel and ignition we can't make any power. It is vitally important that we control, these properly.

The craze with the older RX-7's right now is to buy a used Eaton M90 supercharger off of a late '80s-early '90s Ford Thunderbird and adapt it to the car. Those guys are just using a pigguback ecu such as an S-AFC to add fuel. They aren't adding a whole lot of power. Also keep in mind that the older RX-7's use a air flow meter which knows how much air is being sucked through it. It compensates automatically up until the flapper door in the sensor is fully open. From here it is up to the S-AFC to add more fuel. The ecu's in those cars is far less invasive than that in the RX-8. They can make things work alot easier. There is still no getting around good tuning. Many of thier systems are bandaids and they are missing the true potential of their engines. A standalone is always the best option. Just like any other car, if those guys try to push it to hard, they will blow stuff up.

 

I've been following this marathon discussion and not posted anything due to my complete inability to add any value.

HOWEVER, I do have a check for Richard and a burning desire to see an actual test and buy one of these units!! I also know 3 other guys who are waiting, just waiting to send Richard money if it tests well.

Anyone advising Richard on how to go to market wiht this? Shouldn't he seek assistance in doing the ECU stuff? that seems pretty critical..

hopeful in texas,
JPD

 

I think Richard's pretty sharp on that end of things and will have a product that you can buy with confidence. I wouldn't be surprised to hear that he already has something in mind for the ECU situation. I'm hoping that he will have maps available for the Rick Shaw, CZ, et. al. Of course that will come after testing.

 

After sharing a very nice couple of hours in person with Richard on his home turf, I feel he is more likely to be inclinded to go with the TSI unit. (That is what the "Ric Shaw" unit actually is. I spoke directly to TSI about this and according to them he had nothing to do with the development of the unit, and is just slapping his sticker on it).

If Richard really had his own way, he would stick a Holley or a couple of Webers on it (they are carburettors for those who grew up in the Fuel Injection era :p) and a traditional distrubutor. That way he would have full and total control of his fuel and spark tuning. I'm sure that will throw the cat amongst the pidgeons! You see, to be able to tune it "properly", he needs either to do this, or crack the PCM, or have a 3rd party unit to gain control. I enlightened him to how the TSI unit achieves that, in it's own unique way. He can correct me if I am wrong, but I feel he was unconfortable with the manner in which the CZ/eTrust/Greddy unit, and the rest of them, achieve the fuelling issues.

Cheers,
Hymee.

 

racing beat is on the path of cracking the pcm. they expect to offer direct flashes(i.e. no piggy backing) to the PCM when they are done. i believe richard is much closer to them physically then to TSI i bet jim mederer would love to see Richard's blower :D

 

I have always thought that the Ric Shaw unit is the way to go for the RX-8 unless you don't mind the hassel and expense of going with a Motec or other true standalone unit. You don't have enough control with the eManage. You are limited to adjusting timing as a whole rather than leading and trailing separately. There is alot to be had in adjusting the trailing timing.

 

Hi guys,

If nothing else, this post might just help to bump Richards thread along.

Hymee Prototypes Electronic Multi-Stage Axial Flow using Polymer construction.

After visiting Richard and stealing all his designs and intellectual property, I have taken what I have learnt and started building a electronicly controlled, electric prototype:



This photo shows my able assistant engineer doing some calcs in the background:



Notice the 4 Primary Stages, followed by the slightly narrower pre-secondary stage. Now as the pressure builds we reduce cross section and this is evident in the secondary stage compressor being smaller. Due to the extremely high pressures available in this design, the tertiary stage is quite small, as all that air has been squeezed up so much.

This last photo shows the electronic solid state thermocouple device used in controlling the intercooler. The magnetic field eminating from this device is also used to polarize the air molecules into a pattern that is conducive to the unique side port configuration of the Renesis. This field is generated speficially to the standard (factory) port profiles.



The electronic control module automatically senses the air flow requirements (via the thermo couple), and anticipates the drivers need for power. This allows the compressor to spin faster on demand and give boost without having to wait for engine RPM to rise.

Also in the last photo, in the spirit of Hymee's open policy, you can clearly see the model number and specs of one of the 4 primary stage compressors.

(Hope you enjoyed my humor, RAP!)

Cheers,
Hymee.

 

ROFL!! That is awesome Hymee. Will this work on the Auto 8's too ??

 

Wow Hymee- you've got to get this to market- think about all the honduh ricers that have been putting in "electric superchargers" over the years- you could make a fortune!

 

Damn! Have I got a job for you if your new venture doesn't work out. How about selling bridges out here in the NW?

Thanks for the good laugh!

 

Does it come with the 3 year Hymee warranty he he he :p

cheers
michael

 

Nice, Hymee.... I honestly didn't think you had it in you... You're my new hero.

 

Based upon the size, using your assistant engineer as a guide, the compact size of your composite supercharger should fit without modification to any current engine components.

Hymee, when will this prototype be installed on your RX-8 ?

Nice to know such engineering feats can be hatched from down under.

 

The funny thing is that electronic version would probably be good for a couple HP.

-Mr. Wigggles

 

will that void my warranty?

edit: 1000th post biatch!

 

Wow that thing really blows!!

I'll take a Hymee version!

 

Hymee,

Your'e a Cunny Funt!

As the old saying goes:

"If you can't baffle them with bullshit, then dazzle them with science!"

:p Can I get a ricer version with sparkly hot pink paint and decals on mine...? :D

Paul, seems that the RX8 is a tough cookie to break. Are you regretting in any way, taking the RX8 project instead of the Honda?.
