Sorry, but... Please revise this engine. I didn't even know that it's possible to get such low hp from a 2 litre. The MTBF is bad, so is fuel economy, responsiveness and especially emissions for 2014. You can do much better than that Just put a little effort into it.

[boyercam]

Yes it is rather bad, first starts though!

I'll re-do it soon, following the guides that have been put together. Not really german engineering at the moment.

Well, I look at the MTBF, and I can believe the "breaking distance" is 37 meters.

I believe the issue is that it's 94.5 RON but running on standard unleaded.
If you change it to premium unleaded or turn down the compression ratio until its current RON is less than 91 I think you'll find vast improvements! =)

[boyercam]

Thanks for the tip, I'll give it a try!

Here we are:

Much better, apart from responsiveness

You've moved into the Volkswagen 2.slow range now, Keep on tuning the motor, that was a good first improvement but you should be able to get about 130-140hp on regular gas out of a 2.0 without sacrificing much life or costs.

Very low power in this engine, a Volvo B20 from the 60's has this kind of power. And that is a 8 valve pushrod design.
My Opel has 100 hp out of a 1.6 16 valve.

What setting do you have for the cam? And comp ratio? I see that the engine only require 77 kJ/s, have never seen that low number from that size engine.

[boyercam]

I've uploaded the engine file (since been deleted) if you want to have a go at tweaking it, otherwise I'll start from scratch following the Engine Designer guide

[nialloftara]

I'm on mobile right now and can't edit but try switching to mpfi should improve everything, if you want to keep the costs down still go to single over head cam 16 valve.

I'm getting ready for work so I don't have a lot of time but I have made two tunes for you:

In both of them I made your fuel/air mix a lot richer which allowed me to significantly increase compression ratio and get a lot more power and an improved efficiency.
I also increased your rev limit as you were topping out before peak power was achieved.
