uncle tony's garage gets called out by the roadkill guys

Ok, lets melt some brains... cuz you know... why not...

His test wasn't what was claimed. (technically speaking).

Chrysler made the claim several decades ago. What was around at the time.

Magnum engines ... NO.... .125 offset.... NO...

So, leaving the mildly ported heads out since there was not condition made about that AND the point was to squeeze a "couple" of HP out of something by reducing friction (I think).... I think they need to "redo" the test with an LA engine... with a completely stock bottom end.

Do I discount the test, nope, it tells me on a MAGNUM, with a larger offset, there is no benefit. Good to know honestly. I'm sure a LOT of people (including me) might have assumed "IF" it works on an LA (IF), then it should work on a Magnum.

Somewhere in these threads, i seem to remember the offset being quite a bit less than .125 so that COULD theoretically make a difference if the issue WAS/IS in fact, side load.

Now, I'm sure all the termites are are going to come out of the woodwork and say "You don't believe a DYNO, OMG..."... to which I would, no.. I DO believe it. And a magnum was tested. Cool... Now test an LA, which was and engine in existence when the claim was made. If it shows, no gain, so be it, very cool. But test apples to apples..., something close....

Heads up, I'm not debating anything about this, just tossing this out for discussion sake since there are small differences. They might matter, and they might not.

Have fun with it..
 
this 40 year old theory on reducing friction may have been out dated by todays better oils!! no body i know still using wolves head 30 weight!!!
 
Cool thread and direct connection to the point!

Err, what is 16 pages of 'piston talk' actually saying?
Nothing as usual, its all 'white noise' and has no bearing on the rod err piston whatever...

It was an idea when we all ran factory Bigblocks back in the day!
Testing on a late model modified LA, has no rhyme or reason?

Lets get back to reality and do some real work once again!

For those folks who don't know we may all get nuked soon!

So until that happens lets do something constructive unlike Roadkill and others...
 
For anyone interested on tonight's brand new episode of Engine Masters they test the piston pin offset theory.

The piston flip episode might be new for the basic cable Motortrend channel, but there have been fifteen episodes since on the extra cost Motortrend Plus channel. Today I saw the latest episode on which they test exhaust cutouts. Those Chrysler engineers got it right on those.
I think I paid $24 for a year of Motortrend Plus. It was a great bargain. I don't know what it costs to renew, but for a year I enjoyed it.

I've had cutouts on for 2 seasons and yes they do work.
 
Just in general. Smart people or people we like or admire. Can still get stuff wrong! People don't seem to wanna accept that sometimes. We are fallible creatures after all. Not saying who is right or wrong here. These guys have way more knowledge about cars then my 28 year old brain has.
