Oil Pump Design for my Turbo Banshee
 

I finally finished designing the oil pump for my Banshee. I was originally going to use an oil pump off a 300ex but I would have had to rig it like a negro and it wouldn't have been reliable. So I figured the best way to do it was design a pump from scratch. It was a pain in the ass and took a long time but I think in the end it will be worth it since I'll have a reliable oiling system.

Here's the original 300ex oil pump that I was going to use. I took alot of dimensions from this pump and I'm also still using the two internal gears from it:

Here's a pic of all the parts for the new pump:

On the left is the gasket set. The center is the oil bath and lid. And to the right is the actual oil pump that will actually pump the oil.

Here's the bottom view:

Finally what the whole thing looks like assembled:

The two big holes are where the in from the reservoir and out for the turbo. The actual lines thread into the oil tank lid.

The whole assembly fits underneath the waterpump and runs off a custom shaft:

The shaft runs where the breather hose is comming out of. You can see the 2 screw holes that the whole pump assembly attaches to. The pump takes up most of the free space. With this setup the oil pump will always be encased in oil and everything will be in one neat reliable package. The whole thing is going to be machined from 6061 Aluminum. The pump pieces will be cut on a HAAS 3 axis Vertical mill and the gasket set will be cut on a 3 axis waterjet. Now the only thing is to find the time to actually machine the damn thing. :3


Any suggestions or comments are welcome, I never designed a ------- oil pump before so lets hear some opinions. :8

I have no useful info, but the design seems well thought out. Nice work.

Re: Oil Pump Design for my Turbo Banshee
 

catia owns all cad! it is so nice to work with compared to other software like solidworks or unigraphics.

it looks like you are going to need some edm work for some of the small internal sharp corners (on the lower oil journal?), unless you can get away with finishing them with a 1mm cutter or something.

Re: Oil Pump Design for my Turbo Banshee
 

Can I have a copy of Catia, its worth a try.

good work, but wouldn't an electric pump on a toggle switch be more hmt stye :P

Re: Oil Pump Design for my Turbo Banshee
 

hey weirtech is catia worth trying, in using solidedge V18 right now

Re: Oil Pump Design for my Turbo Banshee
 

I love CATIA. The stress analysis, virtual tool path simulation and all that other good ---- makes it a pretty powerful tool. I'm actually designing my new frame with it also. As for the small cavities I'm just going to use a small cutter. The whole this was designed to be cut with a 1/2 inch flat end mill, besides the oil paths.


Not when you already have a maxed out electrical system trying to power a fuel pump, ECU, injectors, MAF and all the other good ---- that was never meant to be run on a 60 Watt AC stator. ;)

Re: Oil Pump Design for my Turbo Banshee
 

some stuff i made with solidedge 18, i know its not impressive but i had to learn to use the program myself.

So did I ;)

Re: Oil Pump Design for my Turbo Banshee
 

oh come on, you've never been to school for engineering or mechanical design,

Re: Oil Pump Design for my Turbo Banshee
 

Well my job title is engineer so that should answer your question. ;) I've only used Autocad before, catia is a completely different program. (easier to use :8 )

Re: Oil Pump Design for my Turbo Banshee
 

haha u want easier to use check out microsoft visio ;)

Re: Oil Pump Design for my Turbo Banshee
 

catia is a sketcher based cad, where something like unigraphics is solids based, which is slower in my opinion and more difficult for making changes after you have a complete design because of the parent feature relations. it really limits your ability to modify one small area, where catia you can just edit the sketch without having to worry about the effect on the parent features because it will update them as well usually. ug is good for creating drawings after you have a part, where catia is a little behind with their drafting. it isn't as user friendly as ug. most autocad guys prefer ug because of this... for lame ass 2d thinkers only.

i took courses on both catia and ug. if you plan on running something like this on your computer it helps if you have lots of ram, a fast processor and a decent graphics card.

whitey, you using a space mouse? makes life so much easier! space mouse in your left hand, regular mouse in your right and go to town! it makes manipulating your part really quick and easy.

Re: Oil Pump Design for my Turbo Banshee
 

very nice. my only question, and the first thing that popped into my mind, maybe im not picturing it the way that it will work, but will the oil get too hot? Looks like theres no where for it to vent. Seems like you know what your doing, so I imagine you already got this knocked out, but im just curious....

Re: Oil Pump Design for my Turbo Banshee
 

Always wanted to mess around with Catia, never had access to it. Used all other programs though. I was a fan of SolidWorks with the full Cosmo Package. Was a llittle dissappointed when I had to go to using Inventor at my new job.

mastercam X/Inventor FTW!!

Re: Oil Pump Design for my Turbo Banshee
 

Oil pumps need vents ??? Oil temps are not going to be a problem. It will dissapate enough heat in the swingarm tank and if it doesn't than I'll just add an inline small cooler. However I really doubt that it would be necessary.

Re: Oil Pump Design for my Turbo Banshee
 

oil pump/crankcase vent...

anyways, sounds like you got the idea of it...

Re: Oil Pump Design for my Turbo Banshee
 

lol, you got systems mixed up. You can't vent a pump. There's two sides of a pump, a pressure and a vaccum. If you vent the vaccum you'll suck in air or just leak oil like a bitch and if you vent the pressure side than you won't make any pressure, it would be an oil leak. ;)


Your crankcase vent is there to vent pressure from the blowby past the rings. This is a boosted 2-stroke, I'm o-ringing my crankcase not venting it. (but thats a separate topic) This oiling system is a completely segregated system. from the engine.

Re: Oil Pump Design for my Turbo Banshee
 

sweet :D

Re: Oil Pump Design for my Turbo Banshee
 

cool project.

the owner of DYNOmite Dynamometers was the first person to publically turbocharge a 2stroke and offer a kit. His application was outboard boat motors but the concepts are the same.

i was looking at the turbo's he used and noticed they all had Mack truck size exhaust sides whoich he explained was an absolute must becasue of heat. so when choosing the turbo your going to use, you must make sure the exhaust wheel and housing is 2-3times bigger than you calculate it to be. the result of not having a big enough hot side will be a big blob of metal.

Re: Oil Pump Design for my Turbo Banshee
 

nice

Re: Oil Pump Design for my Turbo Banshee
 

The problem isn't EGT heat, its that a 2-stroke puts out twice the exhaust as a 4-stroke. Thats why you need a bigger turbine.


Its ok though, the person before you said that 2-strokes have too cold of an exhaust because they burn oil and the turbo won't spool. I've literally heard everything and the opposite of everything at least once ;)

Re: Oil Pump Design for my Turbo Banshee
 

cool project. when do you thin it will be finished?

Re: Oil Pump Design for my Turbo Banshee
 

i believe its on the same schedule as the stealth shuttle :P

Re: Oil Pump Design for my Turbo Banshee
 

^^^^

HaHa!!!!
Maybe sooner!

Re: Oil Pump Design for my Turbo Banshee
 

I'd just like to see the compression that the cylinder holds compared to how much boost the turbo is putting out, and if the turbo is mildly building pressure against its self with some boost escaping mid stroke. It seems like the whole system would be pressurized almost equally but more pressure on the exhaust side because of the combustion escaping mid stroke.

Re: Oil Pump Design for my Turbo Banshee
 

This isn't the same as putting a turbo on a Civic. :-\ Remember when I started this project people said it was impossible. Its taking a long time becuase nothing is ------ed together and since nothing like this has been done before you learn ---- along the way and stuff needs to get redesigned. I have more time into just designing an oiling system for this bike than I did in all 3 of my turbo kits for my Civic. It'll get done when it gets done, but there has been alot more ---- than just bolting on a turbo.

Re: Oil Pump Design for my Turbo Banshee
 

whatever, sounds like excuses to me.

haha j/k. I stopped reading a while ago, but when's the final product gonna be produced? ---- looks hardkroo :y
