small price to pay.

 

It is weird how something so small can make such a big change in how the car drives and feels. No matter what I end up doing with this car, I think Richard's shifter will be one of the best things I will have done. If you want a quick, easy mod that makes a huge difference, this is the one.

Richard... I had a good feeling on the Mega Millions here in Tx the week. Thought you were going to get my car and some Sponsorship for the AFSC....Damn my luck!

 

Well I don't look better than my avatar, but the dog certainly does!

It is a paradox, I love dogs but I love women more. Yet my brain tells me that the dog will always be more loyal to me. He will always love me, always tell the truth, never cheat on me. He will spend very little of my money. In his eyes I will always be the most fabulous human there is. His biggest demand is to scratch his ears. :D

 

TexasKyle, You're supposed to post that on the shifter installed thread. We need some publisity, I didn't sell any today.

 

I met kari too, definitely a cutie there!

 

Well I've never met her but she is the only woman I could look in the eye and tell her I love her for her brains.

 

intelligent, articulate and attractive. in that order. the horror.

Forget the dogs and women, let's get back to superchargers.

Richard, you mentioned that the bend inside the AFS was the critical design factor. Comparing the AFS to the compressor section of a jet engine, I can't see where there are major bends in the airflow. Except for being mashed by the rotor blades and getting straighten out by the vanes, the air flow goes in the front and comes out the back. Where in the path does the internal bend come in?

 

When it goes out. It can't go where the pulley and gears are. It has to make a turn and go out the side. So a ramped anular groove is cut around the gear case then out the side. This outlet can be timed in any of three places.

 

If the axle wasn't in the center then the belt and gears could all be outside and then you wouldn't need a bend.

 

I'm sure that setup has less polar moment, doesn't run out more then .001, is cheaper and takes less room. And the axial clearance is less too, right.

 

Richard,

Thanks for the explanation. When I read this thread, I think I'm looking over Frank Whittle's shoulder watching something historic happening. It is fascinating and exciting.

You may now return to the dogs and women discussion. I have one of each. One is a loyal, intelligent blond beauty who greets me by covering me in wet sloppy kisses. The other is... I think I will quit while I'm ahead.

 

Good thinking.
Is the welcoming blond a Golden retriver or a Yellow lab?
I take it the other doesn't read the forum. It's good, mine doesn't either.

This brings up a question, should we be reading whatever forums they write into??? Hhhmmmm!!! Pondering the universe.

Everyone at once, check on your womans computer while she in the shower. If it is password protected, demand to know why.
This may prevent war. I know we really don't care, unlike they, but just this once for survival of the species.

 

be scared very scared.

turns out they are all hot lesbians.

in a good way.

That would be OK as long as they brought their freinds home rather then go to their freinds house.

 

I just finished reading the threads about Mr. Paul's short shifter. I'm sold. I didn't think that such a simple mod would be that significant to our already incredible driving experience. Too bad I'm all the way in Iraq or else I'd buy one of these today. It's a good pacifier until the AFSC is finished. BTW Mr. Paul are you going to design anything else for the RX8, ie...exhaust, header, flywheel ect...?

 

Blacklist, Thank you for serving our country. Don't forget to ask for military discount when you do order.
As to other Rx8 parts, besides the SC my next trick is a four way strut brace. I think I have a good idea that hasn't been tried yet. Then some anti wheelhop parts. Don't know what that will consist of though as we haven't studied it, just know it needs to be done.

 

Ooh, anti-wheel-hop parts! The FD guys' ears may perk up too, I wonder how different the design effort would be for the two cars.

I think you will find the 8 is harder to fix. Justtake a look at the shell with the large openings for the doors. What you have is a shoe box with the sidewalls cut out. Not much of a structure. We know Mazda was aware of this when they designed the car. They put alot of work into it to get as far as it is. But whats good enough for the normal owner isn't up to performance work. This will always be the case with production cars. No factory will make the effert and spend the money to overbuild a car.

The consumer will always find a way to exceed the limit. Itis just that the limit isn't very high on the 8. The only real fix would be a roll cage that links everything together. This means front to rear suspension, just like a NASCAR entree. This will not be practical for most owners. So the fix is somewhere in between. Bracing the shock towers seems to help. But there needs to be more conection, frame togetherness so to speak. The undercarrage braces I have seen don't look like they are going to get the job done.

I'm not saying I have an answer, I just understand the problem and will look at it.
There may not be any aftermarket cure short of the rollbar install. Body reinforcement is not practical unless you strip down to a bare shell and weld in more sheetmetal. That would be a case for the pro rally car. They then would add the cage and have a real race chassis.

There has to be something we can find to stop at least some of the wind up.
Some high speed camera work might help find some points. Sounds like something for Charles Hill to try. He has all the temperment assets for such a challange. But anyone can do it and we might have to be the ones.
Anyway I think once our own car is supercharged we are going to have to solve some body problems.

 

Is it just my computer, or have there really not been updates on any of the major horsepower upgrade threads for 6 days or so?

Richard, I have a few questions...

1, homogenization. Will there be any issue involving the fact that the pre-SC portion of fuel will be homogenized, whereas the stock injectors' fuel will not be homogenized? For instance, how much of the final chamber mixture will remain homogenized after passing through the injector spray?

I'll save the other homogenization question for later

2, ignoring for a moment whether the unit is rear or front inlet, is placement mostly determined by the belt?

 

Is it just me, or is this a AFSC thread.....or is it about MIlk????

 

More than would if it was not prehomoginized.
2. ??????????? the belt is in front. The inlet can go front or rear, at the design point.

 

So could a rear-inlet unit be placed where the stock airbox is located, so that the rear inlet is facing forward and the front of the unit is facing the rear of the car? It seems like you wouldnt have to move the throttle around that way. on paper at least.

 

Wouldn't you have to move the TB further? It would be in front of the car on the inlet side. Remember this is a draw through system. Plus there would be no room for the MAF which is before the TB. On top of all that there is a need to have straight tube for a certain distance before and after the MAF so turbulence does not effect the readings.

Life would be easier if all that large tube was not nessasary.
