CRM Motori?

[burgundyben]

Anybody here run CRM Motori engines?

I'm not sure if they are still making them?

My understanding is that the heritage of the W18 goes back to the WWII era Isotta Fraschini petrol engine of the same layout and 57ltrs capacity.

There is clearly a back story here........................

Yeah, of course I'm running a CRM W18, on my lawn mower. What else?
There's no replacement for displacement, as they say over the Pond...

I believe you'll struggle to find anyone on a pleasure boating forum who runs that stuff on their boats.
A military forum is more like it, since they are installed on several patrol boats.

Anyway, I can confirm that your understanding is correct - or matches mine, anyway.
Very peculiar beasts. To my knowledge, the only marine diesel engines ever built whose power to weight ratio is >1.
With Seatek coming close, but not matching that, and anything else (Cat, FTP, MTU, MAN... you name it) following, but nowhere near.

I don't know if the engines are still built (and neither if the company still exists, for that matter!), but fwiw an active website does exist.
If you're interested, I have zero problems to give them a call and ask!

Magnum 63 hull one or two won the Venezia Monte Carlo in horrid sea conditions leaving everyone and anything behind it, including the more no frills performance only orientated Cuvs or Buzzi designed Cigala and Bertinetti. To name a few. It has CRM1850hp and did 70 plus knots flat out.
Recently I know the Captain of that boat , currently named Black Bullet and with Cat engines 1400.

Her journey for the race Rapallo - Venezia in 32 hours and two stops for refueling. And then again racing the shoe shaped country.

Looked at the W18: the specs are mad.
57 Litre displacement!
400L per hour consumption. if my maths has worked.

Point of order! W O Bentley did not want his team to race the 4.5ltr supercharged cars at Le Mans, he wanted them to race the 8ltr, his argument was 'there is no replacement for discplacement'.

The same ethos was borrowed by Texan Caroll Shelby a few decades later where he is quoted as having said 'the're ain't no substitute for cubic inches'.

No back story, a museum near to me has an Isotta Fraschini 57ltr petrol from WWII era, I happened to see the acronym CRM used in an entirely different context and it reminded me about CRM Motori.

I thought it might make an interesting discussion here.

Apologies to W.O., I didn't know that he's the one who used the expression first.
Actually, I would have sweared that it came from the muscle car era of the 60s, also because pretty sure it's widely used also nowadays in the US, when talking of those big block things.
Then again, it ain't the only thing which became popular in the US but wasn't actually invented there...

Back to the point, yep, I believe that the CRM W18 diesel was built around an IF petrol block designed in the 20s, go figure...

P, I really hope you are not offended, but due to your normally perfect English, this stood out like a sore thumb

The past tense or "swear" is "sworn".

Absolutely no offense - quite the opposite, thanks for the pointer.
Btw, sworn does sound familiar, now that you mention it - I just didn't think too hard while writing...
And after all, I guess it's better a normally perfect English requiring some occasional corrections, rather than one so bad that it's not even worth trying to improve it...
