Max Cubic Inch???

[Sashacig]

Whats the most CI you can get out of an engine?? 700?? Might sound like a stupid question. But I was just curious...

[Chris]

Sonny Leonard builds pro mod engines up to 932 cid. Probably not practical, but possible.

[glassdave]

Jon Kaase builds some monsters to but they are Ford based. Saw 900+ c.i. mil stuffed into an EXP one time. If i remember correctly there was a promo photo that showed a coffee can in one of the cylinders. Thing was nuts :D

[skaterdave]

heres a link to sonny's - http://www.sonnysracingengines.com/
you also got kasse and steve schimdt. i think these guys are all pro mod drag guys. i think 640 is about all you can get out of a standard big block until you go to the 5 inch bore spacing and than you need all special stuff. i heard that stottler ahd 700 cu in engine in the mystic cintron.

can you say reliability????

[Sashacig]

Wow!!!! what kind of HP where they making with that C.I.????

[Ratickle]

I've seen engines pushing 900 cu in's. The biggest problem I've found, for marine, they are all one off pieces (Big Chief etc.), and every block I've seen in that range have no water passages. Purely aluminum/alcohol drag motors.

There are some big chief stuff in the just over 800 cu in range with cooling passages. That's about the best I've seen. Still one off special parts with giant price tags. I know a couple guys who would be more than happy to help you spend your money on one though if interested.:sifone:

[DAREDEVIL]

I know the donavan 666 CI makes on mild bases N/A single carb with 89 octane a stunning 980 HP @ 5400 RPM and over 1000 FPT !!!!
But they are 1120 deck hight so its tight in a twin. LOL

OH ,,and suposaly last for ever ???!!!

Its what i heard.

[Perlmudder]

might be a stupid question, but how much bigger physically are these motors? like a foot wider and taller or...?

The decks are 1.4 inches taller on a 11.2 deck Merlin block. That leads to header clearence problems in V hulls. Maybe better in a cat. 632 is pretty common from a standard tall deck. (+.4 inches taller)

Fords can work in a boat! I believe those from Kasse are all hemi head (Boss 429) Variants and he has just come out with a new Boss 429 head that will run on a stock 429/460 architecture with regular water passages. :sifone:

[Sydwayz]

There was a 29 Warlock V-bottom in MD a few years ago with around 732ci IIRC. The damn thing IDLED just shy of 10mph.

[Chris]

The 5" bore blocks are somewhat longer. Probably 3+ inches. IIRC, they're on 5.3" bore centers.

I would love to see someone build an offshore boat with a pair of Packard Merlins. ;)

I saw a boat at an antique boat dealer in Clayton NT last year- looked like a big version of a Magnum 27. It had an Allison v-12 on a gearbox driving a pair of Arneson 6's. Was built by a guy in Michigan I was told.

[Dude! Sweet!]

Hot Rod had a picture of one of the big in Sonny's motors next to a regular big block, maybe 6 months ago, the thing was a monster compared to the Chevy motor.

I'd heard that the big 43 Schiada was built to run V12. Anyone know the whole story?

not merlin though

Powered by a Packard V-12 I am told. :)

How about a 1080ci v16? I wonder if they got this idea from Tractor pullers?

The Torques were sort of the same deal but with V6 IMSA motors right? Or where they a custom block with the V6 heads?

And say what you will about modern boats... You'd be hard pressed to find a better looking boat than some of those old wooden race boats from the '20s and '30s (and their modern replicas of course).

And until you've heard a big Merlin run flat out, you can't really call yourself a motorhead... :sifone:

I think they where copies from V12 lambo's !!!!
Similar to the BPM V12's.

And look, it's basically cheaper than a Merc 1200sci!!:leaving:

A long time ago I believe it may have been Doug Lewis who was involved in the development of a monster cubic inch engine that produced 1000 hp/tq NA'ed!! The engines were in a cat down in Barnegat possibly??

Anyway, I was having an engine Dynoed at his shop after Doug passed away and Danny was rebuilding those engines.... I saw the super deck Big M block with raised cam bore, oversized lifters and the crank as he was assembling it.. This was a number of years ago but I think I remember Danny saying the crank was either a 4.75 or 5" stroke, it just looked enormous on the bench sitting next to a stock crank.... now that was some big azz chit!!

[Geronimo36]

Found a pic and some info....

They were in a Skater called "On the Prowl" They were 1,000hp WITHOUT blowers. Doug Lewis was commissioned to build big horsepower, without blowers, that would last at least 200 hours. They were EFIs and 640ci with the ability to switch to 87 octane.

When I saw them at the shop and they were being rebuilt the internal parts were barely worn!:driving:

maybe some others have better pictures....

My shop is located near a small airport where there is an air museum. A guy flies a P51D out of there. When he makes a fast pass over the building you can hear the supercharger whine and it will make the hair on the back of your neck stand up. They also fly some big radials out of there and they sound good also, but nothing like the Merlin.

[PatriYacht]

The Torque's were a new design but they were based on a 572 ci bbc rotating assembly x 12. They went too far with special gear driven acessories custom made for that engine. Now that they're out of business, any boat with Torque's is a real white elephant.

DOn't exaggerate, only 89 feet long.....:sifone:

Some facts on the 14 cylinder version:
Total engine weight: 2300 tons (The crankshaft alone weighs 300 tons.)
Length: 89 feet
Height: 44 feet
Maximum power: 108,920 hp at 102 rpm
Maximum torque: 5,608,312 lb/ft at 102rpm

[Chris]

Your specs are out of date. They upgraded in '08 :)

5 million foot pounds of torque.

Thanks Dude, I love Merlins and Allisons are OK to.

Back on track, I thought Sterling wound up with the Torque stuff. I realize their V12 wasn't I guess cost effective or maybe over engineered but I give them a lot of credit for trying something different.

[bobkatz]

I rode in a Hustler cat over the weekend that had a pair of 753ci na Sterlings, i think i'm in love!

[Bradz]

Ateco Engines just built pair of 632's with a single carb over 800 hp on pump gas. 140 mph in a 36 Nortech. That is moving for NA engines.

[PatriYacht]

Some of the guys are getting 700 hp NA out of their 540's. Using the same hp to c.i. ratio, a 632 would put out 819 hp. That should be very doable and driveable.

[DAREDEVIL]

510 Ci , on 93 octane solid roller and good internals. Is ~ 680 HP reliable.
598 Ci , on the same as above .Is ~ 800 HP.
So a 632 should easaly do that.

[TMS1155]

There's always the Wartsila 96 marine diesel. 14 cylinders, 114,800 horsepower at 102 RPM. 90 feet long.

So if you glassed three 41 apache's together you would still have room for a three foot cockpit and a 30 foot fuel tank???????????

[Raylar]

We've made a few of these beauties in 632 cubic inch N/A at 10.0 to 1 and 91 pump gas they make 865HP and about 900ft/bs of torque.

And Yea, at around $50K each they look pretty cool too!

It says on your picture 725 HP. LOL

But nice.

What is the price tag on them for 2 ( race purpose ) ??????????

For real now.

Put a Bowtie/Merlin Block 540 with Twin Turbos and 2000hp in even a Marine engine is no problem...or actually a really Big one..unless you drive a straight axle...

I think that is Bud Tresch's boat, owner of Woodbury Cement, down my way (Gloucester County, NJ). Tim Sharkey had posted pictures of the internals of those motors (from the 36' Skater) a few years ago on OSO.
