Just kinda curious... Has anyone ever thought of putting in a v12 in their boat? I'm just thought that would be kinda cool.


Life is uncertain. Don't sip.

why bother when you can even crank out 1000hp+ easily with a small block...   

Torque moves boats. Not horsepower.. There are many reasons big blocks are used more than small blocks. One being the cost of building big torque is less than to build similar torque in a small block. Another is rpm. It takes a small block a lot more rpm to build the same power a big block can produce in a much lower rpm. Which in some cases as in out drives you are limited to Ron's before the gears self destruct. As well as in a jet or even a v drive the gearing you would need for the small block application would kill your cruising speed as well as any efficiency.

Music to the gods huh, well you better be praying to the gods when that pump explodes at those high rpms.

Simply.....untrue

how do you figure? It s simple... A small block to make similar power is at much higher rpms than a bb therefore you must hear appropriately... Look at it this way. If you can run a 28 pitch prop on a bb and cruise at say 50 at 3500 rpm but for a Sb application would need let's just say a 24 pitch prop what do you think your cruising speed of 50 mph your rpms would be?

How do I prop a Berkeley?

I cruise @ 3000-3500, with an 'A'
WOT is ~4600
In the mid 5's mpg
GPS'd @ 55-58, lookin for 60

And the segment continues, we will be back after a short break and continue this discussion on " what spins your impeller"


Sent from my iPhone using SoCalJetBoats

what is your application? And every boat is different... But the point I was making is apples for apples as to why big blocks are used over small blocks. For instance my 468 with a blue printed pump and an A impeller cruised at 50+ mph at 3800 rpm and pulled 6500 wot to get a small block to turn similar rpm and put the proper impeller to accommodate the torque curve and you will not have the same cruising speed to rpm it's quite simple.

Impressive HP in that 468, 2hp per cube?

mine's a stock azz sbc

Or........ The pump cavitates to allow the required slippage.

Just saying.

Well its pretty easy.... Step 1- Unbolt the bowl. Step 2- Hammer,JB weld, and a series of hose clamps the prop to the end of the shaft. Step 3- Floor that bitch! BAM ur done! DUH!!!

lmao

That is impressive. Your turning 6500 with an A impeller? Inducer? What am I doing wrong? Hahaha


Sent from my iPhone using SoCalJetBoats mobile app

well it is actually 6400 but the 5 is right next to my 4 and I'm on my iPhone. And no I didn't have an inducer it was a 14:1 compression 468 if dart heads tunnel ram and dual Holley set up. Far from a slouch motor. If that helps answer your question.
