2.7L CAST IRON BLOCK - WHY?

[RAB123]

I'd be much more excited to see two more cylinders added to a 2.7. That 3.6L V8 CGI block designed to handle boost would bring more to the table, and more consumer interest, than simply scaling up the V6 in volume I would think.

Is that 3.6 V-8 in a production model ? does it have the architecture as the 2.7 ?

Is the 3.0 eco boost bored and stroked or just ?

Do all these fords engines share the same bell housing pattern ?

I'm new to this new breed of engines , I hot rodded my share of the older stuff but never none of this generation .

...

The 3.6 is just the theoretical extension of the 2.7 by volume per cylinder. There might be an engineer at Ford who has tinkered with the idea, but as far as I know there has never been any official indication Ford is making a small V8.

Yes, the 3.0 is just a modification of the 2.7.

Thanks for the info ,

do you know what the mod is on the 3.0 ? stroke or bore or both ?

Both

Both by a couple milimeters IIRC.

Yes - the 3.0 is a bored and stroked 2.7.

Do all these fords engines share the same bell housing pattern ?

Ford has a few different bellhousing patterns currently:
- Modular (Coyote, 7.3 Godzilla, VooDoo, Predator, V10, 6.2) - note the squared-off top similar to the older SBF pattern

- V6 (3.3 NA, 3.5 NA, 3.7 NA, EcoBoost V6s) - note the more round profile. I'm 99% sure this is the same on transverse and longitudinal applications

- Duratec (2.0/2.3 NA and EcoBoost, same as Mazda 4cyl - you can use a Miata trans to make an EcoBoost engine RWD)

- Sigma (1.5/1.6 EcoBoost)

The CEO of the Company behind the High Tech for making the CGI in the Nanoengines , Dr Steve Dawson of Sintercast says that a new petrolengine is in the cards. 2019 he said The company also expects the production approval of a new SinterCast-CGI petrol engine, potentially marking the company's second passenger vehicle petrol engine application. The Nano-engines of 2.7 and 3 liters were the first ones on the market. As they were from Ford why not another one from Ford?

The 2.7 is not cast iron. It's CGI (compacted graphite iron). It's tougher and lighter than cast. The 2.7 was engineered from the very start to be turbocharged and be able to have extreme durability.

Man but I like the sound of that!
Extreme durability and what not!!?

I haven’t been this pumped about a new car in a very long while ??.

Go FORD!

And CGI-engines can be smaller in size and lighter than aluminiumengines with same displacement. Most people assume that an aluminiumengine always is the lightest on. This is wrong.

GIFA World Foundry Trade Fair, 16-20 June 2015

" Prominent among the cylinder blocks on display is the world’s first high volume CGI petrol engine cylinder block, the Ford 2.7 litre V6 EcoBoost, establishing a new benchmark for CGI in petrol applications. The display also included a direct comparison between the Audi 3.0 litre V6 CGI cylinder block and the Mercedes 3.0 litre V6 aluminium cylinder block, highlighting that the assembled Compacted Graphite Iron engine is 125 mm shorter and weighs 15 kg less than the aluminium engine. "

This means that a CGI-block fits in more narrow enginebays and can can be used in more models.

CGI is five times more fatigue resistant than aluminum at elevated temperatures, and twice as resistant to metal fatigue as gray iron.

interesting to say the least , thanks

So, do you think there is a a larger CGI Sintercast engine in the works for the blue oval ?

 

[CGiron]

Who knows. Dawson said that only " production approval " was needed and that sounds like a ready engine but from what OEM remains to see. Ford is a hot candidate as they are the most CGI experienced OEM . Time will tell. The interesting thing is that petrolengines will most likely be made in large numbers.

There is not an issue re-sealing aluminum heads on an aluminum block once blowing a head gasket. if The head is warped from overheating then you get it decked flat and your good to go. I have rebuilt multiple aluminum engines without issue.
