I have made an engine for my (relativity) affordable (£80,000 or $125,000) lightweight sports car hence its high RPM. This baby is going to be the power-plant of what I’m going to call: The Genia 8C. Yes I know it sounds like I copied that from Alfa Romeo but I have no better name to call it… So please comment on the engine and maybe give me a name or two! 
EDIT: Sorry the image didn’t come through first time 
I quite like it maybe a low end sports car.
how about “Carver V8”? or “Landerham 4.0” (slightly alteration of Caterham)
The torque curve makes no sense to me on how thats possible,lol.
Not bad. Two things I’d change:
a) It looks like the horsepower curve is still ramping up when the rev limiter kicks in. This engine would no doubt make more power with a higher redline. Try a shorter stroke and/or better internals.
b) Move the two cam profiles closer together. Double hump torque curves with a dip in the middle is a personal pet peeve lol.
Cheers for the comments! The Genia Carver it is then… the problem is that increasing the stroke and improving the RPM affects the MTBF and I am already using lightweight forged and forged i beam conrods 
So is there any way to solve this problem??
Oh and increasing the cam profile reduces the economy, besides the sudden increase doesn’t bother me much…
You can try decreasing the stroke. You can also increase the bottom end quality.
I could, but the the man-hours increse quite dramatically…
I like the engine but I question, why a v8 ? Just a personal preference ? I, when making a N/A sports car go for a light weight engine… light as humanly possible and squeezing all the horses out of it I can… I also use just regular unleaded, because if it makes X power at his much, then it’ll make a lot more at this much… My favorite engines are my I4’s with 180 horses, being only 1.6L and lighter than crap their pretty robust… lol
The fact it’s a V8 is, because it is a smallish sports car and a 4.0L is too large per cylinder for an inline 4 and an inline 6 is very long, so is unlikely to fit in the engine bay. A V8 also has a nice rumbley sound compared to an V6… Then again, when V10s are released I’ll have a go at making the stroke as low as possible compared to the V8 and see if it is any better 
Strange torque curve though overall if you left a download link when I get this game I would download it add a few more bhp sort out the torque curve and use it in my one and only supercar model I have planned not refined enough for a luxury car.
The “strange” torque curve is the VVL kicking in giving both the benefit of maximum power and economy… that sudden change is when the camshaft switches to another. Select anything but a DOHC 5 valves per cylinder head and then select the VVL option… play around with the cam profile and the VVL profile and see the advantages for yourself…
Well now I know the strange torque curve.lol
I put this together just as an example of how I’d do the same engine. I won’t say it’s “better”, as it’s better at some things and worse at others. Just food for thought.

Coming from the person who told me to shorten the stroke: your engine is almost 20kg heavier 
this engine is going to 30,000-35,000€ “sportscar” like evo etc.
do you realise your emissions are in the 800s even though you are using a turbocharged direct injected engine in 2013?? and besides, the car have the lowest running costs as possible while maintaining a high MTBF anything less than an economy of 20% doesn’t cut it i’m affraid
Considerably yes
