Well, here we go the Roadkill guys have called out Uncle Tony on pin offset. Making more power. I assume they are talking about a stock style engine with stock pistons.



Uncle Tony rebuttal.


Science behind it. This guy was trying to help out Tony.
 
yeah & the piston wear will be worse too
side loading differently (especially on old used stuff)
let alone bore taper in that specific cylinder
weird ring wear etc.
could all be nominal stuff, at that level of performance

the hp difference if any will be nominal
especially on a stock flattop piston engine

if it has valve reliefs on the quench side now
(if it didn't have them already)
it will affect the quench area also, maybe nominal too
"could result in" weird hot spots & possibly detonation too

IMO changing/moving the engineered side loading to the other side
probably isn't a great idea, nominal effect either way, on an OE setup
could even bust piston skirts
especially reusing old cast/alloy 'not a good forging' OE piston
the offset was meant to quiet it down some
not intended as performance advantages
make the piston rock/sideload in the cylinder even more
(could cause a piston slap noise too)

IMO probably gain more by just making/bushing them rods/pistons
to be free-floating at the wrist pins, in std orientation

I'd probably believe 'Steve Dulcich' time in a dyno room
experience over Uncle Tony's too, he claims "the TV guys"
from Roadkill Garage/Roadkill/Engine Masters 'like to talk'

he's one to talk himself...
Youtube channel Bloviator on the internet

maybe he should try it with a domed piston, even a mini-dome +6cc
that would be a hilarious outcome
(just kidding, nobody's that stupid or hopefully)

albeit;
Uncle Tony, does occasionally have some decent tips every so often

I'd suggest to
watch the 'Engine Masters' series about 'Rod Ratios'
season 5/eps. 1 (IIRC)
it's a true look into what happens with the piston
thru the whole 4 cycle combustion process
in the real world, real #'s & real tests, backed up

a simple cam change or rework the cylinder head
or combustion chamber or multiple performance valve angle grinds
is a way better idea IMO just to pick up a few HP, tried & true practices

to each their own

pissing contest & arguing over the internet is lame

Then UT called them out. Build a 318 and dyno it, separately at their own shops. Not sure what that would prove if you don’t run them at the same place at the same time. Atmosphere and dyno differences will negate any piston being turned around. After UT‘s engine that went to Nicks garage I wouldn’t be calling anyone out.
 
Somebody’s is going to test this. When that happens I might be interested in the results.
 
The DC Racing Manual states that the reason to reverse the pistons is to reduce friction.

Uncle Tony made a video about that 318 too. He had little is any fault in that engine being the way it was. I'll see if I can find that video. It was not his fault that engine was trash.

He built it, his name is on it... If it wasn't up to his standards he should have pulled the plug on the build... I sure would have...

Typical "It's not my fault".....

I agree. Everybody does there own thing. If it works for you,, good for you.
:drama:


YouTube is all about the views. Drama creates views. Tony is cashing in on this and the more recognized name 'Roadkill'. He's got a warehouse to pay for........

THIS!
Tony was trusted with and oversaw the engine build - that's why Lunar brought it all to him, after all
(Tony being the supposed "expert" of the two).
As usual, Tony and crew were more concerned with "content" than the actual build - but should have
called it off the moment it became clear what was needed wasn't going to materialize that weekend.
It left his shop and he was the builder of name...

He's a "sniper" - picks and snipes at others to look like he's the smarter guy and get some interest going.
Gotta feed that content monster! He chooses to do so by being the National Enquirer of car video channels...
 
Here is that video of him saying he was only supposed to port the heads.
