this is the intake adapter for some twin turbo engines we are building... it started out as a big block of aluminum and then i machined out an adapter to go from the throttle body size and bolt pattern to the intake size and bolt pattern. the fuel injectors will be inside the intake adapter, will make for a cleaner look on the outside of the engine.. with no fuel rail or injectors or wiring showing.. and the little piece is the fuel injector retainer that holds the injector to the adapter..
and yes that is a manual machine, and yes it took along time to make,,, right after i took one of these pics the big endmill I was using to take away big chunks of aluminum broke and caught the part and through it 30 feet past me.. good thing is it only put a little dent in an edge that was going to come off anyway..
BTW- We are friendly with the GAS crew that did the swap. . They did this for fun not to be competitive or even market it. Think about that for a minute.
Most coatings are over priced bs including the micro polishing (REM). They will provide heat control threw friction reduction but can not due much for strength. If we brake a tooth of a gear it the base there is no coating etc in the world that will help. The parent metal will need to change or size of the gear.
Are any of the gears made of something good such as a 300m metal? If not I could have my gear cutter whip some up. We have found for high load and or shock shafts/gears including steel connecting rods the 300m although not cheap is the best.
Here is my real ??? What type of failure do over revved and over powered drives suffer from?
Thats funny. No, I have not tried those belts. It wasn't blower belt dust, it was from the accessory V belts. It only took about a thimble full of dust to plug that little filter. That is why I got away from them. They are only about 1/2" diameter and about 3/4" long. They were just to small. They would actually starve the engine for air when they got just a little dirty. Just a heads up. I'm not sure what you were going to use for a filter...just don't use them.
By the way, nice work on the mill. Put up some shots when it is finished. i would love to see it.
We haven't tried the gates polychain carbon/blue belts.... But we started out using just a regular old polychain, and after probably 20 pulls on the dyno, there was dust coating everything on the front of the motor! We now run the gates powergrip gt 8mm with the RCD pullies and have never had an issue/failure with the huge loading and unloading of the PSI's when throttling. Still have some belt dust, but not like the polychains.
Will we see catalytic converters on the 1300 in 2011 as per the EPA regs?
Gear teeth can't be hard, but the coating can be for enduring high contact stresses.
Yes, we do have bevel gears operating at 22k rpms. All of our gearboxes use the same methodology in the input modules (interface between turbine input and main rotor gearbox.
I'll jump off this thread regarding rotaries because it is deviating from the topic of mercury's turbo and we can go back and forth at infinitum. My hunch is we will see it whether it is me or someone else doing it.
I had these same discussions when I was told it wouldn't work for a jetski, completely different platform.
saxman, have you tried Gates Kevlar belt. Those have a Teflon coating, but must use their special pulleys since the cog teeth have more of a geartooth profile...not straight cut.
