Thanks. But I think this a crossed post from my s/c thread. But I'm happy for that nonsense to be shifted here!

Cheers,
Hymee.

Fine then, I just posted one on yours.
I was just braging that there was no infighting between us.

I'm just reading your sig and noticed you don't have my shifter. That means you haven't even donated to the development program. You're not even helping to pay my bar bill.
Thus your comments offer no punishment whatsoever.

Or a Hymee cat-back, grill....or sCANalyser...clearly just a free-rider and, by the look of those mods...fashion victim

Hey, that's the spirit Bimbo, like I said it's so easy isn't it.
Maybe I could bolt the Hymee cat-back up to my Greddy SP2, yeah you would like that wouldn't you, ZOOLANDER.

punishr

No thanks, I don't make long term investments.......

punishr

It's called a joke!!!!!!!!!!!
But thanks for clearing that up!!

updates!

Hey Richard, if you want or ever need I have can host any photos you may need as well, and would be glad to do so. Just lemme know if you need me to . . . and thanks for the update!

I just noticed I had some Gmail from Richard. You guys will like this:

nice thanks Ajax

now, it seems to be missing a throttle body....

That's the first picture we've ever seen of the new front throttlebody location.

How about a nice new cast manifold that just bolts on? Better yet how about a carbon fiber manifold that bolts on! Of course a price tag that Lockheed would be proud of would probably follow.

Things you should notice are the raised mount that now allows for the oil filler manifold to be installed stock. This part has alot of other functions glued to it si it is good to keep.
You can see the new inlet at an angle to axial of 40 degrees. From this a carbon fiber adapter will be built to install the TB. By the time the TB is installed it will turn almost straight in. From there will go the AC and inlet. Not exactly sure how that will look.
You can see at the outlet in he rear a cone has been machined that the elbow sitting there will be welded to. Notice the stock intake manifold has been cut off. Had it been aluminum we would just weld a nipple on it and then a hose to the elbow. But since it is polimer that is out and we have to make a new one. Happily it can be built just like the stock one. This insures us that there there will be no trouble we don't expect from a forced redesign.

Ajax can you lighten up some of that area around the manifold for us.

So we have solved a couple of problems associated with the oil system. First the filler then the oil filter access. These are now stock. We will build a plate for the oil filter so you can tap the oil off of it and not have to fight the gauge fitting.

BTW the last numbers we took the other night were at 36,000 (should go to 42k+) and they were 7.3 PSI with a 70f heat rise or approx 88% efficeincy.
I know you want plots for everything but I just haven't done them.

So you see where we are, working out the manifolds and the little details of hoses and wires. Also we are working on all that extra material on the inlet volute.
I have a picture of one of those sectioned so you can see the shape of the inlet passage. I'll get it out of the camera later at the shop.

I'm sure you have questions so I'll just wait for those.

Looks perty

88% efficiency just for the compressor.

Cant wait to see what happens to temps when/if the fuel get added before the compressor.

I dot believe there was not a defiant statement either way so far for where to add the new fuel.

My vote before the compressor. It worked before that way before why change the design now.....

I love the idea of a cast manifold!

John Corbitt

Hey Richard. Twin Cessnas have a silicone flex elbow that goes from the turbos to the intake manifold. They are expensive since they are aviation related. You might be able to have the part made for less for you. You can go online to RAM at www.ramaircraft.com . The part number is 1111-1. It is under ducts. as an elbow

I'm not at home right now so I don't have access to any real editing tools.
If someone else wants to do grab those photos and lighten them, feel free, otherwise I'll get to it when I get home.

The idea of adding more fuel before the manifold is good but what about the idea of the build up of fuel and residue as a result of fuel just sitting in the manifold sections thats valves are closed off like the runners that open at the higher RPMs. the less that valve is open the more build up you will get. So the runners that only open at 7000+ rpm would have a huge build up due to the fact that they are not open very offen. Is this a solid presumption, Richard or Rotarygod, any ideas?

DMBfan

Just shift at 9k RPM everytime to solve that problem

The gasoline is supposed to have evaporated by the time it leaves the compressor. (I think Richard once used the word blender).
Of course instead of injecting gasoline, one could inject a water/methanol mix before the compressor. Both have a significantly higher latent heat than gasoline (= remove more heat), which wouldn't require to richen the air fuel ratio to prevent detonation.

However it would require an additional safety switch in case one runs out of water.

This probably will not happen as the air is going toward the vacuum sorce which is the open port. If in fact it did happen a small 1/8 hole in each blade would handle the problem without any effect on airflow design.
We would love to do it this way for the highspeed fueling but the electronics are more difficult and we will leave this for a later date. In fact this might be easier on a four port. It looks like the four port is dead and they will not be making them anymore.

I really deel that the Mazda is the ideal engine for prehomoginized fuel. It makes sense when you look at its big problem of the extended combustion chamber. I wish Mazda would give me a research project to try this under lab conditions. It wouldn't cost much and the potential is great. Now that we are a tad away from having the install ready it would only take the fueling hardware and managment software. Are yo out there Mazda??

What if that were the breakthrough? Would Mazda switch to rotorys for more models? Does that save money? What costs more to make a rotary or piston engine?
