well the day this SC comes out im going to miss this thread a lot. i dont know what i'm going to do with myself

 

Drive...



Then probably spend quality time in defensive driving class.

Hi all,

I'm a long time lurker here and this is actually my first post. Richard, I'm planning on buying your kit but like most people I want to squeeze as much out of it as I can.

I was wondering if I installed an air-air intercooler if you thought it would cool things down enough to use 91 octane pump gas with the 100 octane map?

P.S. What is the expected perfomance gain of the 100 octane map vs, the 91 octane?

 

have you seen how it works ? No way to use an intercooler .

 

The reason there is no intercooler is due to the efficencies of the axial flow supercharger. The air doesn't heat up as much while being compressed. There for the intercooler is not necessary.

 

I wouldnt even think of trying to improve on this product. A very smart and talented man has spent a while developing this. And he was sober for the most part. Take it as it is to start with. After a little while THEN more options for the package may appear.
I still say that this is the package that will save the renasis for the everyday, fool with the car just every now and then, type of owner. This is the type of system that a MazdaSpeed RX8 should have. It will bring the power up to par with the market competition. And the next time I see Billy I am going to be driving one, let him see it, drive it and hope he will speak with his Uncle.
Heck, who knows maybe RP will be able to go to Italy a LOT

Wonder if Mazda are looking over RPs' shoulder

 

the whole point of the afs.. is to make the car more driveable, and fun... to give the car equal power to the cars ability....

it was not intended to be the tuning make more power do all..... i think mazsport will have that covered.. and pettit and hymee will fall some where in between...

richard is following the kiss system... that is what he has said he was doing...

i do not speak for him... but i have read every word of this thread...

i guess this is an outside the box update...

and to those in the know.. please correct me..

Sort of off topic but I saw this program about the development of the first jet fighters and they were talking about how the ME 262 used an axial design and was superior to the British version which used a different design. Made me think of this supercharger.

 

I saw the same show and was thinking about the same thing. The British design was a centrifugal design compressor. The main performance difference in the planes, according to the show, was aerodynamics. The size of the engine was larger than the German causing more drag. The performance figures for the two engines were similar.

 

richard
can the idle speed be increased to 1 K or does that "mess" with things too much. I know there is differant firing orders and such at the present idle program. Just wondering if yall have had that thought.

We can't change anything in off boost conditions if we want to pass smog laws.
This way we can have exactly the same readings before and after the SC install.
Nothing is telling the engine there is a SC installed on it, it just has some kind of fan between the TB and the manifold. It changes nothing during the EPA cycle.
They have no spec for boosted conditions.

 

I would say it's JUST some knd of fan.

It's a special one with lots of R&D and reliability.

 

Yeah. I think Richard Paul is just being modest.

 

cool and thanks-- I and the Ga Club await.
In almost process of getting Mazsport fuel pump upgrade. Then all I have to do is to get a little stronger clutch installed(mine is stock with 42K on it.), and the coils grounded,then I will be ready.
Smart on the Epa logic.
You really ought to try the downdraft tube mod for the oem oil neck to intake hose. It really does increase throttle response. Easy to do and if you dont like it just plug it back. I also took the acordian intake hose resonance chamber do hicky off. Doesnt do **** but sure looks cleaner and you can access your coils a LOT easier.
Oh and my wife isnt getting the *****--we got a dog instead.
olddragger

 

Sorry to hear about the dog. I assume you had no say in that one
If I was to choose between the AFSC and ***** ASFC would win, but ***** would definitely win over a dog

By the way what is this downdraft tube mod you are talking about?

 

A sporting dog I hope.

 

rp,

check pm.

For those of you who just have to have a version of the Axial flow SuperCharger today, and can adapt to the larger displacement (it's 19 inches long) original application:

a Latham original

Cheers

Mike, Just wondering (a) when, if ever, will this be done; and (b) what, if any, is the relationship or overlap or ???? between the Axial Flow project and Hymee's forced induction program?

 

Well things have improved in the last 50 years. The old unit like on Ebay will flow just about the same mass as the little one we have developed for the Rx8. It will have more max pressure, about 10psi due to it's 11 stage design but flow is close. Those old carbs had 15/16 throttle bores!!!!!!! To get over 100 cfm took 3in hg. 4in could get you 140!!!!!!!
They tip the scale at 33lbs without the carbs!!!

The one pictured can't do anything with the belt they have on it. They came with a wide flat belt and 5:1 or better ratio. The original design was for flathead Fords and used 2 carbs. The first unit was tested on a 272cu in Y-block Ford and reported in the June 1956 Hot Rod magazine. It was written by Racer Brown who tested at Edelbrock on their first Dyno. I have that supercharger in the garage at home. S/N 00001. I also have 2 brand new carbs for it.

Hymee and I are friends, plus he is the distributor for my products in Australia and Europe. We share information but as such it is confidential between the two of us. That is to the customers advantage as it speeds and advances development. So please don't ask what it is that we share because it is still privileged.

 

is there any other type of dog? I like Jack Russels--dont climb as much as Beagles --so easier to keep in but hey--
sure are a sight to see tracking. Fun dogs. Whats the old saying--"the more people I met--the better I like my dogs." present company excluded of course--.

Trying to get a rock solid fuel delivery system done--I track about 3-4 x's per year and fuel stavation happens and is a concern. With the na version--no real damage. Would it be a major concern with an afsc rotary? Increase capacity pump--conversion to a return type system from what i understand doesnt guarantee to solve this fuel starvation issue as it is a charateristic of our saddlebags. I really dont want to do a surge tank.
Working on this

Richard : any chance you will be supplying outside US ?
NZ for instance - you know we are allies right ?

 

Yes of course we will be supplying product down under, we do it now with shifters.
We don't know yet if there are any differences with the right hand drive cars. We will check that out though.
I am aware we are allies and we appreciate that.

Your in the land of Burt Munro, a man I met at Bonneville when I was 18 and still remember him. He made me think highly of Kiwis ever since. Then after that there were lots of your cousins on the race circuit, known for their hard work ethics.
Those guys are famous for working all night long, days in a row.
I remember famously one bloke we called Wombat. He had a tee shirt that said "Wombat eats trees and leaves."

 

lol - think it would have said "Wombat eats roots & leaves" !

 

You're probably right, it was a long time ago.
