C'mon guys why is this hard to believe - Porsche can produce 450HP out of a 3.8L Flat Six, 500HP out of the M3 4.0L V8 is possible with the right components...

I definitely think it is possible, but I have yet to drive a car with an aggressive cam that I like... I wonder how this car actually drives/feels with those cams? Some go test drive it, say you with the m3post press department!

if they really do have ported heads and are running optimized cams, they should have passed 400 whp quite easily. 400 WHP is achievable with all bolt ons on this engine.

Would be pretty close to the s85 output which would be sweet!

I really hope these claims are true. 500hp NA without having to spend $20k on a stroker kit would be the greatest present for our s65. Just cause I said $20 doesn't mean I'll pay $10-15k on your MSL package tho lol. If the price is reasonable and what you claim is fairly close im pretty sure you guys will get plenty of business.

500 flywheel HP is not an easy feat to achieve especially since there is so little scope for raising the RPM limit. Already with 8600rpm we achieve a bit more 'peak HP'

We can all see that it is quite possible to get to around + approx 40-50 hp taking the car to around 450 crank HP. Realistically without the marketing. Maybe 460 in some cases.

Now we are looking for another 40-50hp. This will require some serious work to the heads, some massive cams and then you have the driveability issues below 3500rpm.

Most likely to get to a real 500hp you will need to stroke. If you want some reliability.

It is way way easier to have 500 genuine HP with a real nice supercharger setup. Something that currently doesn't exist on the market. A 500hp intercooled kit would use really minimal boost and therefore produce really nice consistent power even on the track. This is way way cheaper than trying to get 500hp from NA.

390 SAE whp is really about the best we are seeing and that's not on every dynojet either. This is not even close to a real 500 crank HP yet. You would need on a dynojet 430-440 whp to make a genuine 500 crank HP. That fits exactly in what I am suggesting what the extra is needed - +40-50 whp.

Remember, V10 M5 makes an easy 430-440 whp on the same machines stock and that is a genuine 500 hp engine.

I'm a bit (key word BIT) skeptical about these numbers. First off, Akra with HFC is more restrictive than test pipes. Second the intake ram effects are a great idea, but I don't think they will work to their full potential during dynos. Going 100+km/h, yes, maybe, but not on a dyno. Cams can add quite a bit of power if tuned properly. So given the fact that they claim 500 crank hp, this would translate to 414whp and 290wtq assuming 18% loss. Perhaps if they shifted the powerband higher in the RPMs using cams, then yes. But this is all top end.
