The episode where they see how much nitrous you can shove down the throat of a stock 305 is my favorite.

Wish I would have saw those oil pan and windage episodes couple years ago.
I was dealing with dropping pressures forever till I gave up and put on a external wet sump.

The episode with oil levels is pretty crazy too

Was was just going to post that.

Opposite of what we think and less is more.

We know that dyno tuning ain’t the same as in the boat/car tuning but it’ll get you 90% there plus you see so much more (like the oil pressure) w/its sensors/read outs.

I also like that they added a vacuum pump (the industry/keyboard wizards says we need one) on their pan test mule and gained zero.

When I build and tune a hot rod OB, I install a test wheel on the motor, grab my tools and head to an empty ramp.

I leave the boat strapped on the trailer and back it in just far enough to get the exhaust under water to give me back pressure to tune for idle where that fights us.

I set timing, starting, idle, acceleration, mid range and ball park top end this way.
You have all your tools, jets etc, setting right beside you.
A helper/tow pig operator helps but I’m normally solo.

Sometimes up/down the ramp 1/2 dozen times.

The savings in time/frustration is huge.

The episode where they experimented with valve lash was really interesting. They increased intake lash .010" and gained about 40hp, blew their mind. I was watching an episode of Engine Power where they were experimenting with air cleaners on a 408 Ford. They ended up with a 14" like I have and then added the filter top and gained another 6hp. I went online and bought a filter top for mine the next day. I need to look for an episode that experiments with rocker arm ratios. Thinking about going to 1.8's. My AFR's still flow strong to .700 and the 1.8 would get me to .660.

Next on my watch list.

Ive seen similar on the air cleaners.
They believe it has to do with straightening/directing the flow into the mouth of the carb.

And, me too on the rocker ratios.

Youd think if your motor could handle more cam this would do the same/similar.

Loved the Rod ratio episode, I’ve long believed people wasted far too much time contemplating it. If you are giving up stroke for rod length, that’s especially stupid.

Once upon time there was also a destroker vs stroker SBC 377 test, showed there was no difference.

I watch every week, very interesting stuff. In my area it's on Friday nights. (2) 1/2 hour shows starting at 8:00 PM. If anyone gets a chance YouTube Finnegins jet boat. It's insane.

I dont know why you guys all obsess over this stuff, according to all the 16 year olds all you have to do is put the stickers on your windows and you pick up 100+ horsepower.

Watched that one today , pretty nice increase from 1.5`s to 1.6`s on a 700hp engine.
MotorTrend has every episode , 4 seasons worth . I`ve been watching a few everyday , learn something new everyday.
