Stresses on a 10,000 RPM L61/LE5 crank pulley

Designing a crank pulley for 10,000 RPM ecotec.
Keyway no love motor, and notice the expanding of the crank pulley snout where it fits inside the oil pump. No wonder GM says to get hardened oil pump gears.
No idea why video went SO FAST. lol

SolidWorks?



Paying someone to install parts and bragging about it being fast, is like watching someone bang your wife and being proud to raise their kids.

Yeah any time you take videos in solid works you have to do everything very slowly and for long periods of time or else what is shown above will happen. Iirc think you can change the amount of frames per second the program records at, but I haven't used solid works in years so I'm not too sure. Nice job though!

My android brain was able to take that all in in the 2 seconds, lol... Will said pulley be lighter then stock, I might buy one even though I have no plans on going higher then about 7800rpm and without balanceshafts.



Don't buy from MANTAPART!!
There is no easy ways to get HP, no magic box or gizmo... And if you get more hp, there's no way to make your car still behave and sound like a stock one. More hp usually makes your car louder, more vibrations and harder to drive...but still people hope or think maby there's some magic way to have it all, comfort, stock sound and drive.

The pulley is going to be as under driven as I can make it. It is either going to be titanium or a tool steel. Still going over the material properties to decide on the best material for the application. Its something like 45 percent under driven LOL.

Yeah but on most other sites you don't have to pay for the option of editing posts.

I'll take one in stock size btw.

You don't get it do you? It needs to be as underdriven as possible to keep stress down on the material. Secondly, underdriven more makes more power, that is the entire point of revving the bitch out to 10 grand.

And Finally, you're an idiot so stop posting up like a hard ass all of the time. Do you even bolt your own parts on to your car yet?

You need omgwtfbbq'd, at least your android brain does anyways.

Are you that retarded? I'm not telling you what YOU want, I'm telling you WHY this new one is being made.

This one is being made because someone specifically asked for it made as described. And children........ take it easy.

I just like throwing my hot white cream in his face. MY hot white man cream. /always sunny reference.

edit: other than that though, I meant why as in why its not a stock size pulley.

KFLO is 100% correct. The smaller the better.
yes, a stock sized pulley would add even more stress to the pulley. 10,000 RPMs and stock diameter pulley would make designing it even harder.


Ben, I was not going to tell anyone it was for you, but I guess you didn't care.
Also, the alternator pulley you got from me .....looks to be fine if I can keep the size of the crank pulley small. If the crank pulley gets bigger we might need a under driven alternator pulley.

Hmmm, how did you determine the resisting torques on the accessory pulleys? Also, what did you assume the brake torque would be at 10,000 rpm?

Did you guys know that ATI makes an underdrive pulley for the ecotec???

ATI SuperDamper

I don't see the need to rev that high without changing to a very large cam and maybe changing the FDR

^^ I know its easy to assume (especially here) that someone is trying to do this on a mostly stock street driven engine... but this is for a full race car with a built motor.

Do you have solidworks? if so I would gladly send you the file. it is easier to see than explain.

Fully built doesn't even explain it. Maybe built to the full limits of everything.
