Default Re: KPaul was right,Take that back 90 deg V-4 is narrower and has perfect primary bal

Uhh, check my post.



I said, and I quote, "Your inline 4 won't have perfect balance. You can get either primary or secondary balance, but not both. That is why you see balance shafts in 4 cylinder engines (in cars). To be balanced, you need it."



I said nothing about the V4. I was talking about your I-4.



The V4 will have perfect primary balance, but not perfect secondary balance. A 90 degree V engine, regardless of the number of cylinders, has perfect primary balance but suffers from secondary imbalances.



So, in trying to claim I was wrong, you were wrong again. You should learn to quit when you're ahead.



BTW, BSME, MSME, PhD EE.



I learned more in my four years at the motorcycle shop then I did in 11 years of college. Some of the most ignorant people I've ever met were well educated. Educated fools. Some of the smartest people I know barely graduated from high school.



NEVER equate education with intelligence.

Yep... I was PreMed stud until I ran into Organic Chemistry... To me Physics and Math are easy compared to Chemistry... Most engineers have brains wired to understand Physics and Math... Chemistry is a lot different IMHO... I have much respect for Chemistry, Chemists and Chemical Engineers.... Doctors too...

Thanks for the advice and knowledge.... Yep my I-4 doesn't look as good as it did.... "Some of the most ignorant people I've ever met were well educated' I am sure my wife would put me in that category.

Much Respect blitz

Thanks.



Life, like engineering, is all about tradeoffs. I used to view the world as black and white. As i get older (and hopefully wiser), i see way more gray. The gray is what makes it interesting. Problematic at times, but way more interesting.

blitz, to the best of my knowledge a 90 degree V6 or V12 do not have perfect primary balance. A 60 degree V6 or 12 does have PPB, but only if the crank throws are 120 degrees apart. VWW
