A gentleman whom is developing a F1 for the 8 tells me that it will work on the AT if some one will build a intake manafold for it and tells me that someone else inqired about this and did have access to someone that would build one. I have done a search of the AT threads and can not find any mention of it. Looking for some help here.

Isn't the intake manifold the same as the 6-speed?

What is an F1?

OK was trying to be cute - super charger = F1. Must not be as he is one of the leading developers of the super charger and tells me that his unit will work but he is not making the intake manafold for the AT.

edit:
I mean the 4 port engine.

So I gather that it will not bolt to the stock intake on a four port. I assume that you want someone to make an intake manifold that will except this Supercharger. One must have a base plate design/size, height requirements for the manifold.
I don't understand why this company does not want to make one (manifold) for the 4 port.
Seems to me if you want a manifold some will need to come up with some type of specs for the mateing of the two. Why have they not pursued this themselves?
And these people are leading developers? Sounds funny to me.

We are few and the development money is great and the return? While I may not like it I understand.

Let me answer that since it is me you speak of. Building a one off manifold is a time consuming thing. Building one that is productioized is even more consuming. There are men out there who can hand form things one part at a time. However they are rare and busy. We don't do those things in house as we have none of these artist types on board.

These cannot be sold on a production basis because they take to much time and are to expensive. We have these made for our protptypes by making all the machined parts like the flanges and swedge tools. We give those parts and a mock up engine to a fabricator to build the first part.
From there we either make a pattern for casting it or build a jig to fabricate them as quickly as possable. We get the tubes prebent by a vender for multi unit builds.

We don't even see making money on the amount of Rx8 6 port kits we can sell. One or two four ports we can't put the time into. As it turns out the two engines are similar enough that the only thig different is the manifold so a whole new kit is not nessasary. You will also be responsable for your own tuning.

On top of getting a manifold like you would have to we need to take time to supervise and engineer these things which takes us off other projects. Some of which we make money on. Even if you do the different parts it is going to cost us because we need to take the time to guide you along the way. Where we can just sell a standard kit without much personal contact the AT will cost us all that personal involvment.

I may have just talked myself out of doing them at all.

Richard: I did not ask your permission to use your name earlier so I did not. I hope you did not missunderstad my post. I said that I understand that it is not economical to build something for a few. I was not complaining only stating a fact. I also own a business and understand time alication. Economical does not always mean money it can also mean time and resources. Please do not let my post upset you into not helping AT members with their needs. Your answer to my earlier queston was helpfull and I in fact did find the person of whom you wrote about. I will not mention his name because he did not give me permission but he is free to use this forum if he wishes.

OK so I now know where you are coming form with this.
Are you looking at a cast or a tube type intake system for your application? A tube type is more feasible at this point in time than a cast model.
I will look into it with a couple of people I know, and see if it is something they would consider.

Phil I had no problem with you or what you said, I was responing to everyone else and that on response you had.
My last comment was tounge in cheek, don't worry about it.

In fact I think the four port will get more out of supercharging then the six port, % wise. What I'd really want to do someday is build a system for the four port with the fuel goint through the compressor. The idea is helping with the rotary weakness of keeping the fuel atomized. Mazda should sponsor that project for thier own information. It could be a big step, or maybe a failure but they should try it. It would be cheap.

Thank you. I would not know the difference but if a tube type is more feasible then that would be the way I should looking. Cost is not the controling factor but important. Engine Management may be the controling item. As soon as I get an idea about costs and feasablity then I can make some type of decission of the direction I want to go.

RP, I'm interested in this comment. What makes you say the auto will get more of an increase percentage-wise? I'm still learning about FI (aren't we all), and I'm just curious why the auto will get a bigger increase. Any other comments you have relating to FI and the AT would be appreciated if you have the time. I enjoy reading up on this sort of thing.
