Wait until Big Dave gets a chance to play with his DW28 / 300R combo for a summer and gives us some top speed numbers and impressions !!!!

Pauls been playing with his and it’s already well into the 120s with a normal load. It’s so fast He text me the other day saying he’s starting to think his twister/300x is his safer boat

Kev,

This is the same boat. Paul sold it to Dave and its in IL. waiting for sunshine... Propellers are a big part of the puzzle for the torque and gear case of a 300R.

Stopped in the magazine isle of the grocery store today and front page/cover of the two Moto Cross mags they carry is all two stroke.

Interesting considering the 4 strokes revolutionized/rescued that sport too, 10 yrs ago ��

Eight years of BoBumbling along followed by the promise of an obese oinker, everyone that wanted to stay in business pushed their chips in towards the "four stroke swing" knowing they would be next if they didn't ...



After this country's savior stepped up and sent her to the pig farm .. he had a few zealots to broom to the curb before he could move on. Has done a great job considering all of the homocrats that have stood in the way.
Since the cloud of death has past by .. at least for the mean time, the motocross industry was quick to get back to race bikes instead of the oinker agenda ..
As far as boats , and four strokes .. it's all the power , gear case and props fault why they don't run like the five litre's that they are .....

When they brought the 4 strokes into F-1 road racing, King Kenny called them diesels ��

When they brought the 4 strokes into F-1 road racing, King Kenny called them diesels 😂

Before leaving for Europe to dominate the world in 1978, he lapped the entire field at the Daytona 200 on a 500cc square four. (0W69)
When he came home in 1983 he won it again on what was the peak of 2 stroke development ( YZR500 that was 680 cc for Daytona ) It took another year for the chassis to catch up with the power when he won his third 200.
After that, it was .... the diesels





The 1975 Indy mile is still one of my all-time favorites ...



As it relates to boats ...

If the 2.5 Merc makes 260 / 280

And a 3.0L makes 330

Shouldn't a 4.6 make 480 / 500 ???

And the one with a whistle on it make 630 / 650 ???

Just axein for a friend ...

[baja200merk]

Word on the street is they already made almost 800hp from the 4.6

in 08 at jasper dave had a guy from Yamaha racing there he said If u started from scratch and made a 3300cc 2 stroke v6 it should make 700hp.

I was goin easy one em ...

I think we talked about the same time .. and I said : If there was a feasible way to put chambers on an outboard ... it would make 900 HP

But as Walter Kaden said in the 1950's .. You know the pipe is getting to be the right size, when the bike no longer has any ground clearance ...

I ran sliding pipes when I ran kneel down.
They do work ����*☠️��

The dirt bike mag I just read did a story on hot rod 500 2 strokes.
They built a KX500 that made 72 HP’d at the back wheel!
Id call that 80 at the crank.
Said it’d destroy any of the 450 Diesel works bikes.

Interestingly to me, the 500 dirt bikes are lower R’s than the smaller bikes and have similar porting to our V-6’s.
80 HP x 6 (cylinders) = 480 HP @ 3 liters, or 180 cu ins. (Naturally aspirated)
3 liters x 1.5 = 4.5 liters and 720 HP’s.
Yeah, 2 strokes suck.

Back in the ‘80’s there was a new road racing class (WERA) that was basically a unlimited rules class.
1100cc 4 stroke displacement and forced induction allowed.
Kenny laughed and said he could beat em w/his 250 class riders.

His 250ccc team beat them on the short tracks but not the long ones.
Kenny paid go to make the F-2 250’s into 400’’s and beat them on all but the longest tracks.

He then sent his (when he had his own teams) 500cc team and they destroyed the open class Diesel bikes and that was that.

People can talk all they want.

After Kenny flat tracked the TZ750, he famously said they didn’t pay him enough to ride that thing.

Seems like if ya don't have sliders, all ya have a is great spectator seat ...

Our OMC guru buddy say's .. they got Brigg's + Stratton porting, all you can do is sleeve em out ... BIG

hey btw .. didn't you walk in there with a set of calipers ...

That was great story you told at lunch that day ...

[Instigator]

Never got mic’s past his metal detector.

Story at lunch???
I have no recollection of that story.
But...., I do know things.

On the sliding expansion chambers, we “pull em” (shortening their tuned length) when we come out of the turns.
If you watch close, you will see the rooster tails lay down when that happens. More proof of their effect.

[HydroSkreamin]

OK...back our regularly scheduled program...

Z06Man texted me that the 24 Skater made 2 back to back passes at 122.5 with 2 guys and 3/4 tank of fuel with a 35 DeWald thru hub out of rpm. It’ll be interesting if he gets a Cleaver-style prop on it.

Nice work so far, fellas.
