Piston reversal.

[Mike]

The answer is connected to what Andy is going to try And also backs up my thoughts as to why it won’t work.

Richard Holdener has a really great youtube channel where he tries a lot of different engine combos and then dynos them to see how well they work. He has been talking about flipped pistons for a few months now, asking if they make a difference or not. He has acquired a Dodge 5.9 Magnum engine to test this theory. I find his channel really interesting, he is a very likeable and knowledgeable guy, even if I will never try most of the things that he tests. You will need to keep watching for the test, which he hasn't done yet though:

Or slap a bosch pump on a Vauxhall Magnum

He’s either done it and is selling the idea for millions, or it’s blown up on the dyno and killed him dead

I just had a little end failure on a 2.4, but the pump is still running fine. With the introduction of LED lighting I thought gaslighting was out of fashion Mike.

Don't suppose you could kill him any other way but dead..??

I've been a subscriber to Richard's channel for years. l love American V8s. When I was young the only one available to the common man in the UK was the Buick 215, aka Rover, where was Ford?.

He never actually got to flip the pistons in this video, so what does it prove?

You may be interested to know that at one point the Chrysler corporation recommended piston reversal for race engines using standard components, their race team did it, you may wonder why?

[Mike]

their race team did it, you may wonder why?

For circuits where torque was more important than power and as it was for a race engine, the wear rate didn't matter?

How's yours coming along?

Back in the day the 1970 s. My brother and I did a routien freshen up on his 440 six pack.
The usual rings bearings touch the valves. While we were at it we decided to follow chryslers
advice and swap the pistons bank for bank. This changes the piston offset from .090 from one
side to the other. Chrysler claims 12 hp. Buddy let me tell you. Those were not shetland ponies.
Thoes were bad- aSS CLYDSDALES. The motor reved faster in the mid range and peaked higher.
Henry Ford was on to this because I understand his flathead v8s had the crank offset away from
the centerline of the v. The new kawasaki 1000 sport bikes have done the same thing on there four
cylinder monsters. Some people say less friction some say lon

I know it's only word of mouth evidence but.....

It's an interesting idea, I don't know whether it works or whether it doesn't, I'm not saying it does, but it's a diversion from the tedious rule of thumb conventional. What's wrong with considering it?

[andypdq]

From a purely mechanical point of view it will work, I can resolve forces, pressure and dwell influences, I don't know. I'm honest.

[andypdq]

How's you innovate mods coming on Mike, have you upgraded an LED or changed a bit of trim?
