They sell fully built race engines capable of over 1000 hp. Not a bad price either. This isn’t the platform for crazy high HP for me but 500 hp high revving turbo engine. Maybe 8-8.5k redline. I am getting excited thinking about it.

What's to think about. Just do it lol

If my engine blows im getting the 350 hp NA K24

I recently discovered their cam article and I thought it was very interesting! 500hp is going to be a lot of power, but I think that would be really tough keeping down! I’m going for 400 to the wheels, which probably equates to around 420ish-425ish HP at the crank.

500hp is easy on a stock motor. You can probably rev to 7500 also but why?

I looked into it two years ago. With shipping and a full engine pull and reinstall you are in 20k on a fwd setup. A no go.

Because high revving engine is just more fun. GT3 with 9k rpm, my R8 at 8700 rpm or even a McLaren turbo engine over 8k rpm. It’s just fun to wind out the engine.

You need lots of mods to supoort revving this high. Keep in mid that revving high but not making power to redline is lame lol.

you will need very big injectors and a fuel pump that can handle the revs.

Built motor, big ass turbo. etc

the cool thing to have would be a decent 4 port head

Ditch the R and TT the R8. lol

All the cars I listed make power all the way to redline. I've owned a few of those and still own one. Mclaren used to taper off a bit, bigger turbo fixed that.

Considering that I am already talking about a built motor. It's a given that necessary changes will need to be made. Bigger turbo, fuel upgrades etc. I believe their motor can safely rev to 9k rpm. Just need proper fueling and turbo to make use of it.

I really want to keep it NA. That's the main reason why I bought it. Or else I would've just bought a 750s tbh. Type R is my daily.

I have to check but there might be one or another 8bit hard limiter in the code that could keep you from going past 8160 on a stock ECU but I could be wrong. I will check on that.

Mclarens have great heads, such as the R8 and obviously the GT3. All of them can do over 9k very healthy. R8 has 20 injectors and Mclarens are port injection also 2 per bank that also helps a lot.

The R has a integrated exhaust manifold aka "headifold", and it´s DI only. At 9krpm you have a very small window to inject the fuel before you are too far into compression so you will probably need the 2000cc xdi´s. These two factors are a bit complicated to work around but maybe it can be done. Another thing to worry is wether the transmission can sync at thoses speeds or not.

There are some turkish guys making a CNC 4 port head, I wonder if anyone ever tried this. PPR I believe

Yep! Mine is essentially their Stage 1 engine since I added the Ferrea valvetrain. Runs great! Just did a health check on it yesterday, and I'm at 150psi on all 4 cylinders and leak down under 6% on each cylinder, and a flog this thing pretty hard at the track. I'm not looking for big horsepower though. 500+hp on a car that is seeing track use would be overkill. I'm closer to the 375-380 mark.
