Hp per cylinder

[vi top shatta]

In the outboard performance world what is the new normal as far as hp per cylinder. With the advance in technology I assume some should be able to squeeze 100 per hole by now. Any thoughts?

[Chaz]

Without an expansion chamber , thats a pretty lofty goal.

2 HP per cubic inch is doable ..

any 3cyl OMC race motor, 49ci were about 120hp ( 40 years ago)

[PanRonnie]

the better quistion to ask would be what would be normal HP per liter today ( thermal effeciency )
100HP per liter is not uncommon while staying in one piece

so you can see the the 3 liter mercury 150 fourstroke is underpowerd
that's why Chaz is going to install a Turbo on one and show us how it,s done!
meanwhile we get to sit on the beach with a beer in hand

just buy a 150 3 cyl e-tec, 1.9ltr
PS I always wondered about dynamic misfire on a DFI outboard? big decrease in low speed fuel consumption?

See , proof positive ... That I'm just a metal ***** that will work for anyone ...

Like I said .. It's doable ... even OMC could do it ..

Fall's a lil short of the 100 per hole question . Aye Ol chap ..

boosted could be looking at 100/hole?
I guess 2 valve Nascar v8 is 100/hole

Nitrous!!!!

a turbo , 4 holes what could go wrong!?
mother mercury already took care of the design schematics so parts can be ordered next week

fast and furious on the water , i guess we can't ask Vin Diesel!?
somehow that just sounds wrong

Here you go

Can't imagine running a turbo without a modern EFI with deto and EGT sensors... $hit happens too fast under boost!

[Instigator]

Well if we’re going to include goofy **** that never really worked, let’s not forget this.

From the fertile mind of Rick Gillman.

[Instigator]

Rick got it running pretty good but what he described was the same as the turbo.

Had to tune it for your target rpm.

That blown V8 that Rick built worked quite well for a lake motor. Rick could not get it to rev as high as he wanted it to. He broke the blower shaft and stopped working on the project.

[Stoker boy]

I sent Rick a text to see if he wanted to chime in but he is traveling at this time.
