It's real! Now I'm excited. This could be the best Christmas present ever! Go Hymee (and Phil)! :D

That Takahashi has been playing for LONG>>>>> Time. I knew of him since I was hooked on baseball during high school. He play for Giant and I was a keen Yomiuri Giant team then. Giant in the mid and late 90s are much like the Yankees.

I remember his first name is Yoshinobu or something - like Yoshi (Like the computer game from Nintendo ;)).

There should be a Takahashi as well pitching - he is a pitcher for Hiroshima, where our cars are from :D

oh they just got Bronze ... I mean the Jap Baseball team

Sweet! I knew it was a KB SC. Good luck with this project. A SC'd 8 will be fantastic.

Way to go Hymee!

Man things just keep getting better every day..........
Thanks for the info Hymee
Good luck with your project.

Mate, that is a seriously attractive bit of gear. And great photo's BTW.....

Gomez.

Hymee, how heavy is that compressor? It looks very solid. and the completed intercooler? Next time put something next to it so we can see how big it is.
Where does that bypass fit? What size are those rear bearings. They must be just greased as no oil inlet/outlet are visable.

Looks good, I'm keeping my eye on you. It's smart of you to use the Motec for first dyno development. How far do you think the stock nozzles will take you?

Supercharger Project Plan - Where to from here?

I am going to attempt to outline where this should all go from here (and where we have got to so far):

Phase 1 - Dreaming
Way too much dreaming was done, but I needed to have realistic intentions.
Complete? Well - perhaps I am always dreaming

Phase 2 - Inital Research
Do lots of reading, and talk to lots of people. Intermixed with a lot of dreaming as well!
Complete

Phase 3 - Decision Time: What Hardware?
Turbo? Centrifugal S/C? Roots/Eaton S/C? Axial Flow S/C? Twin-Screw S/C?
Which manufacturer?
What Intercooling technology?
(Note: I would dearly like to try an Axial Flow as well. But my budget restricts me to one for now)
Complete

Phase 4 - Procurement
There came a point where just talking and hypothesising about it only got us so far. It was time to just get the stuff and give it a go.
Complete

Phase 4 - Get it running
This is the phase we are currently entering. Initially we want to get the blower mounted somewhere, and plumbed into the engine. All done so it will work on the engine dyno without total regard for where it will ultimately fit. That is in the back of our mind, but initially we need to get something running! Once it is runnning, we can package it properly in a later phase.
Current phase

Phase 5 - Dyno Testing
Seeing how it performs, testing various combinations of "boost". Validating the efficiency of the cooler. Exploring the requirements / capabilities of the fuel system. Getting optimum tunes for the huge matrix of operating conditions. All done under full control of the Motec engine management system.
Future phase

Phase 6 - Packaging
Once we have all out data, and now what we can achieve, we need to fit it all in. We have variuos mounting brackets to design and fabricate. And the same to be said about a number of ducts, adaptors, castings, bushes etc. All so it fits in perfectly.
Future phase

Phase 7 - Restesting
When we get it all in, we need to re-test on the chasis dyno, and on the road. This phase will also entail calibration of the piggy back ECU with lessons learned on the engine dyno.
Future phase

Phase 8 - Enjoying "Instant Torque" :) and never look back!
Future phase

I hope this impresses the pants of you all. I hope you can see we are going to do it properly, and that a lot of time and effort needs to go into this.

Some more pics...

Stuff on the bench, thinking about basic parts we need to make to get it running:

Cheers,
Hymee.

Amen!

i got "dibs" on the "donor" motor when he's done!! nice pics hymee!

Mission accomplished!

I forget, was the plan to destroy the donor motor learning the limits of the renesis? I thought I read that someplace.. might not have been Hymee though.

Top notch, Hymee. Keep it like that, can't miss. I wish I could help, man, this kind of stuff really gets me going! Best wishes!!!

I did pretty much say that in the first post on this topic, but I don't think I said anything to the contrary thus far. I don't think we will aim to do that on the first run. Perhaps it might never happen with the combo we try - who knows? There are so many variables. There is also various interpretations of "blowing an engine". I think the critical thing is if the apex seals can stand up. If we get to a point where they fail, I think that is probably be a good point to stop for starters.

Cheers,
Hymee.

let me first say....that I've been observing the site for the last three months, which is how long I've had by RX8 and it's the best site ever. The supercharger project has me really keen and I'm in for one as well....keep up the good work.

Hymee,
How long have you budgeted for time during this phase?

Certanly appreciate your dreaming, financial commitment, and progress reports. Being almost halfway through my warranty mileage, I will be checking your phases closely.

Onward ho mate !

We saw you skulking back there! Welcome aboard :) .

...and since your first post was on one of Hymee's threads, I assume you know about his other products. Buy a Hymee grille kit and exhaust.....the quality and execution of his stuff is top notch, and the proceeds will help hasten the supercharger kit development :D .

Go"spruiker"mez ;) .

We would like to have 1 or 2 installed by Christmas. Some SA will ask which year ;)

Cheers,
Hymee.

Awesome Hymee. Your plan of attacking the supercharger issue mirrors that of mine. I hope everything goes well. Twin-screw is the way to go. :)

What are you planning on doing with the intake manifold?

edit: I'm still in love with your exhaust. Hopefully I can buy it soon.

Phase 9 - Breaking the transmission

And then finding out what specifically is breaking for people, and then developing an alloy gearset or whatever. :) (Seriously, I've seen several companies attempting FI, but is anyone working on improvements for the transmission?)

Not to detract from your work so far of course--it's looking good.

Sidestepping the clutch at 7000rpm will have that effect! Apart from some strange clutch plate failures I've seen reported, most off the gearbox/diff probs relate back to severe abuse, don't they? These cars aren't Hemi equipped with Dana rearends....why do people treat them as such?

Hymee i think you have a bit of a fan club here.

Now i understand why you moved the thread.

Looking very impressive, as there will not be many aftermarket supercharger suppliers.

Hehehe - I didn't move it. A "higher order" fan wanted to shift it for me ;)

Thanks for you support.

Cheers,
Hymee.

If you're happy with stock performance, that's fine. If you're running a screwcharger though, you're going to almost certainly putting more stress on the transmission, and beefing up the transmission would probably be a smart thing to do.

I'm sure will find out about this when the time comes. But we might keep that for another technical thread please, and leave this one on the topic of this supercharger project.

I'm also sure those willing to do this mod will contemplate these downstream concerns.

Cheers,
Hymee.
