New engines are installed and ready for spring

**Chaz** · 11-11-2022, 10:14 AM

Not tryin to argue .. but you out of anyone should know 2500 ain't 3800 .

I'd go from Moroso, Orlando or Bradenton .. to Stanton, Milan or Martin .. and pick up .3 tenth's and 9 to 11 MPH .. just sayin

It is similar to how I break engines in on the dyno. Get the coolant and oil temp up, shut it down check it over. Then do a couple solid power pulls working your way up to max rpm. Shut it down check the oil filter, lash and maybe a retorque on heads if its a copper gasket deal. Then more tuning and running it WOT. The most important thing for proper break in is load, RPM and a properly tuned engine.

Customers will ask what the break in procedure is and they are stunned when I say none after the dyno testing. Its 100% ready for battle. Anyone selling a racing engine with a drawn out slow break in procedure is just trying to get you closer to the end of the "warranty".

Maybe true on my Tuff.
I race with turbos though haha, I run 198-200 if the DA is 600 or 4000. Somedays you run 55psi of boost others might be 65psi+.

Not bad .. it only took 34 posts .. for you to prove my point ..

Atmospheric conditions have an effect on the ability to produce horsepower.

If they didn't, you wouldn't need extra dome pressure to get back to where you were.

I remember a couple years ago .. Putz crying like a new-born @ Bandimere, I needed you (Scott Taylor) to give me an extra half hour to get spooled up ...

I rekkon, sometimes it don't matter what ya got on top .. if ya can't get it to move off the bottom ... buuuuwaaawwww

Yes Chaz you must be smarter then me.

Really ..

Thats very disappointing, I thought you would be up for a civil discussion on water grains and their effect on detonation, power production, etc.

Guess I was wrong about you .. my apologies.

Comadore .. nice hooptie .. there, everyone should be ecstatic now ..

Nothing to debate lol. Water grains are piss for making HP! Timing is your friend if you are air pump limited. Gm makes a nice humidity sensor to use to take action with in that department.

The price of new four stroke cats is so high it makes sense to upgrade what you have for a lot less money. When I bought the boat it came with triple 280's. Then upgraded to triple 300X and picked up 10 mph. Now triple 300R should be another big improvement.

Wouldn't 2 450's have been lighter/less drag=faster?

We talked about that option in depth. On the top end, it might be faster....Maybe. It would require an extensive re-rig of the boat, plus the 3rd motor will make a huge difference when it comes to acceleration. It is a 36 footer, lots of mass to push. We mostly run on smaller lakes, so the extra torque will come in handy. The boat is setup extremely well as a triple, so it was the path of least resistance....And let's face it, it's cool as hell. Lol.

What was the speed gain going from 280’s to 300X’s ?

Im sure BZ will chime in. Light load, perfect conditions about 6 or so mph. Real world conditions, fuel and passengers about 10mph. The 300x motors can cruise at 90mph without breaking a sweat. Those 280s were absolutely screaming to get the boat rolling. Sounded cool, but they were grenades. The 300x motors were better better in every way. Can't wait to see the 300R motors with big props, higher x dimension will do. Below is a clip from 6 years ago when Brad first put the 300x motors on with not so great props. He picked up a lot of speed with the modern 5 blade cleavers.

I spoke at length with friends who have both engines including Larry. Twin 450s are a lot more money than Triple 300's. Also would need to go with a dash panel on the 450's which is big $$$. The 300R are an optional analog friendly engine, so the Smartcraft and the gauges in the boat will work just fine. In addition, the throttles and shifters would need to be replaced on the 450's as they are DTS (digital). All told it would be another $50,000 to rig twin 450 vs the triples 300. I believe they would be faster top end with the twins, but triples punch real hard and the cool factor is much higher. It was an easy decision.
