It seems that this platform is really good at all power levels except for anything past 750whp. Is there a reason for that? I do not see many n54's in this 800-1000whp power level. Everything about this platform is good to me: Cost of car, cost for FBO and good power on FBO, good cost for single turbo, looks nice, is a 6 cylinder. List goes on, but I cannot see the reason why there is not many cars past 800whp. And the ones that are past it, have alot of small issues, or so I heard. I am wondering if there is an alternative platform that can make this kind of power easier and more reliably and without many small issues.

Probably because they have 6-cylinder engines.
How many N54s have you personally built to 1000HP before complaining about others' failure to bypass obvious physical limitations?

An alternative platform is a Bugatti V16. Those hit 1000HP consistently.

I am not complaining about anything, I am simply asking for the reason so I can educate myself. We see 4 cylinders like the 4g63 and 4b11t those are making into the 800-1000 range. What holds this motor behind?

[relative4]

Those engines have little in common with the production engines. If you want to completely rebuild an N54 to race specs, the sky's the limit.

N54s hit 6-700HP with no engine modifications.

Most owners dont want to spend the money to build the engine and rear end to handle 1000whp at 750-800whp the car can handle that on a stock motor and rear end. There is also the fact that unless youre looking to have the fastest car out there and be setting records 700whp is already scary fast and starts to border on unusable on the streets.

For 800whp i think the N54 is a great platform. Any more than that you’re pretty much guaranteed to be looking at a built engine regardless of brand and at that point i’d be investing in a Z06 or some sort of corvette

I see what you are saying, I thought I read online somewhere that the reason is that the n54's heads do not flow very well. Even when ported.

Probably because most people don't have super deep pockets with fully Forged N54's

Head flow is a huge limiting factor to why we dont see 1000hp+ N54s

If you use the N54 as a daily driver, it’s probably to a great idea to push it to it’s limit. Paired with a manual transmission, the N54 is a fun car to drive. I chose to keep it reasonably maintained and drive it as it’s designed to driven.

I think the biggest reason is that you can't really hook up that kind of power very easily....and, when you start talking big numbers and big money like that.....there are much better options out there. Look at something like a typical LS motor.....1,000hp is pretty easy, you don't have all of the fueling issues like the N54 does, and the LS is going to hold all of that power much longer than the N54.

The N54 can make big power.....but it's not the best option if you want to build 1,000+hp.

Also...don't forget about the car than the motor is in. When you start talking 1,000hp in a 335i....axles, differential, clutch, etc,etc all become the weak link. Not a whole lot of aftermarket support out there for that platform.

I think it is more like no one wants to spend the time and money on this platform due to the community/market. Everyone just wants cheap easy power while doing the least.

Not to come off the wrong way but the guy above me was complaining about turbo kit pricing being worth half the car.

You have to pay to play!

Agreed, but to be fair most of us don't have deep pockets, lol.

More isn't better, better is better. The platform sweet spot is not at big power. Stay around the ~575-625 whp mark and reasonable reliability can be had, putting the power down is mostly doable and mods are affordable. Go bigger if that's your thing but you're going to struggle more with reliability, parts, lag, etc. Nothing wrong with wanting big power, it just becomes more of a tradeoff and more expensive the further you go.

What would a better platform be for bigger power? I am thinking LS3 vette maybe? Though, turbos are preferred so maybe an EVO X? Open to suggestions.

The only site with what I would consider a legit list of real 800 dynojet whp n54 they are all built motor. So roughly 10k starting for the motor & head alone and goes up to around 18k. That is motor & head alone.

700+ seems to mainly be single turbos 6266/6466 or the like in lb/min with around 28+ psi on 100% E85. Very few twins make the 700s those that do are spun VERY hard and likely out of their efficiency islands.

Lots of different ways to get above 700+ whp. At the end of the day it costs $$$ to make the power and then be able to put it down. Platform is very friendly up to say 550-650whp. After that you drop coin generally.

What are some better platform to go past that 650whp threshold in a cost perspective? EVO X or LS vette?

Exactly. If I'm going to spend $10k on a motor that makes 1,000+hp....I want it in a chassis that can put that power to the ground. Why would I put it in a 335i when I could have it in a camaro, mustang, old muscle car etc,etc,etc....with a 4-link setup, and a trans and diff/axles that can handle that kind of power. 335i's just aren't designed for that kind of power, and the aftermarket support for it just isn't there. Hell, there is only one company making upgraded clutch packs for the 6HP21 transmission.....one. If there was more aftermarket support out there for these cars, I think there would be more people making crazy power.

Like others have said....the "sweet spot" is 600-700hp. It just doesn't make sense to dump a fortune into the motor for more than that...unless all you are interested in is bragging rights.

Use an LS motor...and put it in anything you want. There is tons of support for the LS platform....stand alone DME's, custom wiring harnesses, plug-n-play setups for just about anything you want to put one in. Getting 1,000hp out of one with a turbo(a) is pretty easy......hell, for the price it would cost to build a 1,000hp N54 you could probably have a 2,000hp LS.

It's all about the aftermarket support.....N54/335i is lacking when it comes to big HP builds, that's why you don't see many.

My E92 can fit a 265 tire IIRC. Not very big. Basically have to run a super aggressive tire if you want to try and put the power down. A custom correctly done widebody that allowed me to run a 325 rear would be nice but serious $$$. You can dump money endlessly into basically any platform. At some point you realize you would be better off buying another platform.

All platforms have useful limits. After a point you have to invest a LOT more to go farther and be able to use it.

What other platforms would be better? Everyone is pointing towards LS though I just cannot get over the bad looks of a C6 vette in my opinion. They also cost way more used than a 335i, though maybe makeup for it in cost to mod?? Are there any other platforms out there than are not V8's that are suited to this kind of power that I can research into?

Nissan GTRs can make ridiculous power... but you need to pay to play for sure.
