    • How to reliably tune your N54 to 600 rwhp

      Many people on BimmerBoost chase dyno numbers. Bragging about 800+ rwhp is fun. That is, until things start to break and repair bills start to add up. The N54 motor can make big power but the reality is for most people 600 rwhp is plenty and we forget just how much power that is.

      Chris@VTT put together a good article on getting your N54 to the ~600 rwhp level. Check it out below.


      Hey guys,

      While I think most of the users here on BB are a little past this, but I wrote an article about how to get 600 whp out of your N54 powered BMW. It's not a DIY but goes over the basics of what it takes to get there from our perspective -I hope some of you find it useful. Screenshots and .pdf attached.

      I do want to reiterate, there are MANY ways to do this, and plenty of good quality parts out there, not everything that's good got mentioned. If you have questions, just ask, we're always glad to help.

      Chris

        Do you think the GC lites can still hit 600 whp (and torque) with a 2psi loss due to being at 5280 foot altitude?

        You would have to push a little harder, but they should have no problem hitting that on the right tune, and fuel.

        I think articles like this are very important. I'm probably going to front page this.

        Everyone gets caught up in dyno numbers and thinks 800+ rwhp N54's are the norm. That is not the case and honestly going past 600 rwhp can cause a lot of problems if you aren't properly prepared for it.

        People forget 600 rwhp is A LOT OF POWER. For the majority of people, more than plenty. Making 600 rwhp reliably is a lot more fun than pushing things and breaking things.

        Good stuff.

        Thank you sir, I (we) do appreciate it. We're working on a series of articles covering the basics; like my WGDC article, this one, have some more coming ranging from Spool vs. Lag to Turbo Failure Analysis, etc. etc. So far the responses have been very positive.

        All of them will be useful.

        Sometimes people get intimidated here and I don't like that. Everyone starts somewhere and not everyone is looking for 30851058105810358105803 kagillion horses.

        I searched the webpage and may have missed it but I didn't see a link to all of the articles. Is there a repository where you have them all posted?

        Great write-up. I already knew pretty much all of this, but it is nice to read it all in one place and get some fresh ideas that are based on tested modifications and results.

        We'll post them on the website. Only other article that I've released was my "WGDC and what it means".

        Great article Chris!

        Gives everyone a great idea for return on their investment. Biggest part of any build is definitely establishing the purpose and goal of your build. Then matching that up with your budget/timeline. Should help any newcomer or student of the game figure those out.

        Single barrel is getting more and more interesting as the price drops.
        Could someone using it give us his thoughts about it ?

        We recognize this. Within the next few months -I hope- I'll be shipping my car out to CA, then flying out shortly after and we're going to go over the whole car. Level 3 suspension refresh with M3 parts, upgraded sways, new clutch, GC's, single barrel, new FMIC, LSD... the works. Then I'll drive it back to AZ. Arizona only has E50-E55, and I'm "only" looking for low 600's on my stock motor 130k+ beast. During this work I'll have a chance to really take some good install photos and do a proper write-up -I will most likely focus on the fueling aspect since that is relatively unknown compared to the turbo upgrades. Should be a good experience.

        That's great, but is there people not affiliated with VTT running single barrels ?
        Not saying that you are biased or anything but i'd be great to have some outside reviews you know.

        We had enough parts for 50 shotguns manufactured. We are almost ready to make another batch because we are almost out. There are many people running it that are not affiliated with us, that no one has posted a review always comes down to the same. People with no issues usually do not post anything, disappointing, but true.

        Any idea of the power at 25 psi and zero timing advance?
