Here’s my pass at it. Same maximum power, but with a four valve head and VVL for better driveability. Also note the 9200 rpm redline with no valve float or other warnings at standard quality settings.

i think its funny when people consider 1.3 to be tiny :slight_smile: in my eyes 1L isn’t even tiny haha

Did some more tweaking, and managed to squeeze out 216HP

Size increasing and 100 RON fuel, eh?
We will see :sunglasses:

Here the BMMC reply.
220hp, cheaper to built and more economy too :mrgreen:

Did some further tweaking and managed to increase HP and economy while reducing material cost.

I’m not sure that I’ll going to use steel for this engine. I mean, 25 kilograms (50lb more or less) more for a little 2hp more and one 0.0X% of economy more. It’s chaper but… I don’t see the real bargain in case is going to be fitted on a car. The heavier engine is going to waste all the efforts of the fine tuning.
What do you think? :wink:

Here is Yugo Motors’ attempt (hope I ain’t too late with the contribution). Runs with 95 octane fuel.

Turbocharged? You are cheating :mrgreen:

12

Hehehe :wink:. It doesn’t use 100 RON petrol at least and the volume is very close to 1300cc and not 1330cc or something.

13

I don’t think the ron matters for a semi race engine, and 30cc more isn’t that big of a deal as long it’s still a 1.3 liter’s. Your engine is 24hp more than mine, but mine has more than double the responsiveness and almost 3% more economy.

I know this is cheating, but just for fun, I changed all the part’s quality form standard to max and did a little more tweaking and managed to achieve 244HP whit out turbo all at the expense at double the material cost and 1000x the man hours :laughing: .
