13b Rotary 2 O/B leg bell housing, which alloy ?

[Cobalti]

I have almost completed the mould for the bellhousing to fit my 13b rotary turbo to a 2.5efi leg. I was wondering if any one is an expert in the difference in streangth brtween aluminium and magnesium. The bellhousing will be heat treated for streangth. Magnesium would be nice for the 30% weight saving. A sacrificial anode would be a must, but if too much streangth is sacrificed, its not worth it. I would appreciate some oppinions, thanks guys...

I will post some photos soon.

We are testing the Remesis RX8 motor to see how it copes with lots of boost from the turbo.

Fun, fun, fun...:cool: :cool: :cool:

i will love to see some photos

would it be for sale
i have very nice and fast engine and i will like to see it on the back of my boat

It will most definitely be for sale, together with all the necessary adaptors and sump (fits in the leg where the exaust used to go), to make it work as soon as I finish all the R&D and iron out all the bugs. It is a complete bolt on item, where no original equipment gets modified, hence allowing for return to standard for resale purposes.

how you think this will work on the back of a boat
10.04 1/4 mile on street car

No question about the power to weight ratio with the hair dryer.

Wait for my updates, and see it as it evolves into outboard form. See my first post about my ideas, and the update. There is little expense spared on this project.

Others that way follow will be supplied with all the necessary information to make the motor work in a vertical position. Then, how they build the engine remains up to the individual, their ideas and budget.

Its great to get rid of all reciprocating components!! :cool:

Back to the original question, how much weaker than alloy is magnesium?

[joe bloggs]

I think Rod Hadfield of Castlemaine Rod Shop was casting his own chev blocks out of both alloy and magnesium awhile back. He might be able to give you some info on the relavant properties of each metal.

keep the updates coming, can't wait to see the final result. what are the initial hp and torque figures you're aiming at? Any chance of moving to a 20B or even a quad rotor once everything is sorted?

[Cobalti]

is doing the bellhousing for me. Rod I have known since my hot rod days, and has sold the business. I know through him about the difference in strength, but he is far from a real expert in the field.

The end plate is the same on all Mazda rotaries, so what configuration one is to use remains to individuality. I for my part am opting for 2 rotors and a turbo, and the Renesis RX8 is what we are doing R&D on this for weight savings as I have a target of 180kg.

500 hp is very possible with my set up, but that will not be at the beginning. I will walk with this before I run, but I definitely intend on running, and with 450foot/pound of torque possible it will be fun.:cool:
