How much power can be made NA?

Nice, I did make 368 one night, but it never made it again. My car currently makes 356whp, but if you look at all my uncorrected numbers, it makes 339, on most all of those runs. I’ve dynoed my car over 50 times. Just finished last night installing an 80mm hemi throttle body, and porting my year old manifold lol. We will see if it does anything, a few members have tried bigger TBs or porting the TB and say it makes a difference, but we will find out for sure. I have a chance to buy PTE cams right now, but the guy wants 2000, and brand new CatCams with springs and retainers I can get for 2000. I am waiting on a 90° Silicone elbow, because the stock e55 elbow hits the fire wall, it’s barely to big, and crack it last night try to get it on. Have you seen my build thread, 2002 E55 build?

Thanks for the helpful post, yet I still think it's incorrect.
I don't how how long ago it was that you were playing with a sb2, but here's a link to a supposedly 844hp sb2. Well over 100hp/l for a lot less money than yours took to build.

M113K rods were redesigned for lower compression and increased strength, not the ability to rev higher.
I looked up Kleemann's 55 K3. It's pretty basic and I doubt a lot of thought went into it:
55-K1(N/A): An optimized ECU software upgrade.
55-K2(N/A): K1 + a set of stainless steel tubular exhaust headers and downpipes.
55-K3(N/A): K2 + super sport camshafts.
So this gets us "Up to 435 HP and 585 Nm (433 lb-ft) of torque."
Pushed to the limits? Not even close.
I've seen posts online of their manifolds. They're mid length and the quality isn't great.
They also say their super sport camshafts don't require upgraded valve springs. Not exactly sporty.
So by actually putting a bit of thought into things, I reckon a great deal more power can be unleashed. I don't need fancy equipment or a million hours of test and development. An educated approach is all that's required.
Porting and polishing could have the ability to do a lot, but it's largely untested. I definitely know that the factory inlet manifold stifles things. That would be something worth addressing.
I really don't know where you're getting your numbers from. 3k for porting and polishing? Even if I put 20 hours into my heads it would only come out to £1000 assuming I was charging £50/h.
My labour is free. I only pay for materials. Its useless quoting prices as it means nothing (and your figures are crazy).
By trying to put a dampener on things, you've just reinforced my theory that the m113 can make power. Thanks.
