What "bolt ons" bring an s52 to 300hp and what's the cost?

[BimmerTim]

I'm not the op. You don't have to keep this thread alive at all. I will update my build thread.

How about we all just sit back and see what I can do rather than speculate.

Yes indeed. I don't doubt someone can engineer some cool crap to put together a highly tuned S50US. Hog out the ports. Install hot, HOT cams. Increase compression. Install a trick ass valvetrain, larger valves, solid lifters, etc. Design, simulate, and build a tuned intake manifold and custom exhaust collector to have maximum performance at upper engine speeds.

Regardless of the actual hp I end up making, it will be a highly custom and in-depth build and it will yeild some impressive numbers.

You should have just said this, instead of saying, I'm going to make a 350whp S50US, and to mark your words.

Isn't that the exact kind of pompousness that we should all strive to avoid?

yes, my appologies. I was also trying to take some heat off the op.

All I'm going to say for now is stay tuned, cuz it WILL be a pretty rad build.

^ good call bimmertim.

Recap:

You: "I'm going to do something never before done"

Us: "That's basically impossible"

You "But I'm an engineer"

Us: "What else have you accomplished, and how do you plan on doing this?"

You: "Doesn't matter"

Us: "Well then we have no reason to believe you can do this"

You: "You guys are pompous jerks who try to prove they are better then everyone else, instead of supporting ridiculous claims from someone who refuses to back up their experience or ideas, but just wants us to believe them and lick their sac a few times"

I guess this is what I was trying to say, only I sounded like a dick. I was also sick, and taking care of my sick wife, when this thread started. haha.

I love hearing about detailed, ground up engine builds and how it all works together. It's the other way around that I don't like. and I won't take wild claims for granted. ;)

GL on the build, whenever it happens

I've already began gathering parts, and I'm getting quotes for some machining.

Sorry to hear that you and your wife were not well. I understand that sometimes things can get heated pretty quickly, specially on the internet. I'm sure I come off as a dick on some of the other forums I frequent sometimes.

Maybe the "Mark my words was a bit much", but that is still 100% my goal, and I see no real reason I can't get it, or at least get real close.

He explained quite concisely why you won't get to that number.

okay, how about this. in order to make your magical 350whp, you're going to need over 100% ve at 9000rpm. the 3.2l crank has an 89.6mm stroke. at 9000rpm, you'll have a mean piston velocity over 26m/s. Even race engines don't go that high. Never mind even the E46 M3 CSL doesn't go over 100% ve, nor anywhere near that high of a redline.

Thank you for another great post, bud. Really helping out.

can you link to your build thread?

[LowR3V'in]

I can see an us s52 making 300hp. Don't those
things rev out to 10 or something?

No need for me to repeat what has already been said numerous times.

And basics. Tell me specifically what the euro and NA 3.0L S50 have different? Take away the intake and exhaust. Leave just the block w/internals and the head. What is the huge difference? Besides the obvious dual vs. single vanos.

Post #143

I've built E36s in the past, including your beloved Euro S50B32, and I'm fairly certain that I can find the power I want in a US S50. If for some reason I can't, I will take the criticism.

You've done an excellent job of trolling. Don't know the differences in the motor, yet claim to have built one.
