I'd like some help trying to build the Honda F20c. I'm not sure where I"m going wrong

Going from the wikipedia, we have
Displacement: 1,997 cc (121.9 cu in)
Compression: 11.7:1
Bore: 87 mm (3.4 in)
Stroke: 84 mm (3.3 in)
Rod Length: 153 mm
Rod/stroke ratio: 1.82
Power:
JDM 250 PS (183.88 kW) @ 8,300rpm & 22.2kgm (217.71 Nm) @ 7,500 rpm
USDM 240 HP @ 8,300 rpm; 153 ft lb, 207 Nm @ 7,500 rpm
Redline: 9000 rpm
VTEC: 6100 rpm

From this, I have the following settings:
Current Year 1999
Inline 4, Aluminium, 87mmx84mm, Forged Crank, Forged H-Beam, Forged Pistons
DOHC, 4valves, Al, 11.7:1, 61 on the lower cam, no VVT, VVL, and 100 on the upper cam
Multi EFI, Single TB, Performance Intake, Premium Unleaded, 12.3:1, 83, 9000
Long Headers, No Valve, 3", HF3-way, Reverse, Reverse

I'm only making 235hp.

Some quick observations I have are:

9000rpm Bottom end part is reducing lifespan. Is this right? No combination passes this in 1999
Fuel System. I haven't been able to get any engine to have a fuel mixture richer than 12.3 with it saying I'm running rich. Is there any factors which can change this?
The F20c header exhaust goes to a 2.5" exhaust, which drops power down to 195hp in Automation

Just some feedback to maybe fix some calculations. If I've made any mistake in my setup that anyone sees, can you let me know

You don't have to limit yourself to a 1999 tech year just because the car was released that year. The F20C was far ahead of it's time considering it took another decade before Ferrari could beat its power/liter. You could also try to max out the quality sliders and see if that helps.

Try: 82cam/100cam, 12.4 fuel mix, 100 timing, 8600rpm limit, 3.25" exhaust, and straight thru mufflers... it might not be 100%, but it should get you 240 or more HP.

Nothing is ahead of its time. Either it can exist, or it can't. The game needs to reflect reality.

this is the best i could come up with.

But there can be something that is better than average for its period. There can be technology that is more advanced than average for its period. Finally, there can be an engine that uses more advanced technology than average technology for its period. Now, the thing is that Automation's tech year represents average technology for the period, not the most advanced one.

the engine is not ahead of ot's time, it's using the best tech honda has. the cylinders have molibden and iridium weave to withstand friction for a long time at high rpm and ceramic coated pistons. everyone can make a powerful engine, but making it reliable and adhering to regulations and octane limits it's the hardest part.

But by automation standards it IS ahead of its time, that is how it works in Automation. Regardless of if the real engine is actually "ahead of its time" the point is its better built than the average engine of the era and had more effort and tech invested in it. This is represented in automation by it being ahead of its time...

i've been trying to do an F20c 3 days ago and i failed hard with only 228 hp

After studying the way it operates and what kind of components it has i`ve hit it spot on.

and the restroked version f22c

Hi!!

I tried the F20C with yours initial specs and I did this

Sorry my english

I don't mean to threadjack, but I've been having problems trying to recreate a couple engines, myself. Was trying to do the 2ZZ-GE from the 7 gen Celica, and the S50B32 from the E36 M3. I had a lot of difficulty trying to get torque figures to match up in terms of RPM, because whenever I'd up the cams to get the horsepower right (at far too high an RPM), the torque peak would also rise.

Oh, also had this problem trying to recreate a Tipo F131 from a 360 Modena. Things seem biassed towards higher-RPM output, and I'm having issues even getting a flattish torque curve on the left side of the graph. Does this fall under 'nothing is set in stone'?

With this in mind! Would it be much to ask to have a way to set the VVL engagement point, in RPM?

Cheers!

The VVL engagment point is automatically set at the point where it'll give you the most power. So at every RPM it checks if it would be making more power on the high or low cam right now, and if it's more on the high cam it swaps.

i saw that if i set the high lift cam more aggresive it shifts the engagement point higher. at 100 setting it shifts at about 5000-6000 rpm and at 45 it engages at 3500 rpm. is this true?

Yes, it is true. It chooses the higher of two powers, and the high cam reaches its power later, so it engages later.
