How to Make 400WHP On Your BMW F30 335i N55 Engine For Under $2,000!

[@Astonvman007]

Finally, someone who didn't go the cheap route of a catless DP! Thnx for explaining the octane/ethanol process!

[@InlineSixAuto]

I actually ended up trying a catless downpipe to see what the difference sound and performance was

[@jaymills85]

​@InlineSixAuto and how did that go?

[@InlineSixAuto]

Catless was a bit louder but nothing crazy still sounded the same overall since I had the stock muffler on. There wasnt any significant difference in performance from what I could tell. And it didnt really smell that much worse than the high flow cat. @@jaymills85

[@jaymills85]

@InlineSixAuto ok I got stock mid pipes with secondary cats still but no muffler, I want to delete the cats but I'm afraid it may get too loud or my not sound right straight pipe, I don't know.

[@InlineSixAuto]

@@jaymills85 Yeah I think that's going to be too loud and may add some rasp. may not sound as good. And drone would probably be really bad.

[@SirGraffitiArt]

Doing the e30 mixture every time you need to fill up sounds like a huge pain, might be fun for a week but to have it on a daily driver would be a hassle

[@InlineSixAuto]

Yeah for some maybe. But I don’t find it a hassle really for me personally. Though I do I have a shell station that’s really close to where I live with both the E85 and 91 together. Also I usually get gas every week to week and half which I know depending how much you drive you could have to fill multiple times a week which would be more of a hassle. So it’s not for everyone.

[@SirGraffitiArt]

@@InlineSixAuto Yeah im in the same situation with them both offered at the same pump, the hassle part is more having to use a calculator everytime. any idea what kind of power you would make with the same mods and a tune rated for 93 or e85?

[@InlineSixAuto]

@@SirGraffitiArt For the calculator, all you have to do is adjust the fuel level percentage in the calculator for your fuel level at the time of fill up and it calculates it automatically the exact amounts of 91/93 and E85, only takes a few seconds. If you do a stage 2 93 octane only tune you would make around 370whp if your f30 is RWD with these same mods.

[@SirGraffitiArt]

@@InlineSixAuto Im definitely gonna give it a try once my supporting mods are on, my commute runs my tank dry about once a week so well see, also im xdrive not rwd

[@SirGraffitiArt]

@@InlineSixAuto i appreciate the info!

[@SHWELL11]

Thanks for sharing. Im FBO, the only thing I havent played with is E85/30 fuel. 400WHP is the goal, since i feel it is the sweet spot for something with some decent get up ad go, while also being tame enough for daily driving duties.. 2016 535i.. Considering the MHD Ethanol setup, seems it makes it easier to deal with.

[@javianjohnson8746]

Thanks for the EXTREMELY detailed explanation on e85 at 12:40

[@F1FanCanuck]

E85 varies considerably and can contain as little as 51% ethanol and as mush as 83% depending on your location and the season. As a result, if you’re mixing fuel to obtain a specific desired octane level you should always measure your fuel before mixing to determine the actual ethanol content. Also, the Stage X tune you’ve selected doesn’t allow your car to have a higher ‘knock’. You’ve misunderstood what that term implies, how it applies to your tuned ECU, and what your car is actually doing at different stages of your ECU tune. When you select your Stage X tune (in this case for E30, aka 94 Octane) what your ECU is doing is allowing the turbo to increase the boost pressure of your intake charge air to the point where it would otherwise experience pre-detonation caused by the heat of the extreme compression of the air/fuel mixture - even before the spark is delivered from the ignition system (spark plug). For those who don’t know what pre-detonation is, it’s basically a process of auto-ignition that (in this case) results after the hot compressed air from the turbo mixes with the fuel being squirted in by the injectors, and reaches a point where it spontaneously ignites. This is a particular problem in boosted cars because when air is compressed by the turbo it produces an extreme amount of heat - and the higher the pressure, the higher the heat. A FMIC will help cool the charge air, but at very high boost pressures, even the best FMIC won’t be able to cool it enough. When this hot charge air mixes with the raw fuel being injected into the engine, the air fuel mixture will spontaneously ignite if/when the temperature/pressure of the air fuel mixture reaches its auto-ignition point. And as you’ve no doubt figured out by now, the temperature at which auto-ignition occurs drops as pressure increases (inverse relationship). Now to be clear, the charged air from the turbo isn’t hot enough to cause pre-detonation on its own, but once the fuel air mixture is in the cylinder and it goes through the compression phase of the combustion cycle, the increased pressure of that compression (much higher pressure), combined with the ambient heat of the charge air (much less heat is now required), is often enough to cause pre-ignition / pre-detonation before the spark is applied - creating a distinctive ‘knocking’ sound (hence the name). Except…. Octane is a knock-inhibitor, and at the right percentage, it will prevent the air/fuel mixture from pre-detonating (aka ‘knocking’) while still in the compression stage of the combustion cycle, despite the higher temp of the charge air produced by the turbo delivering that air to the cylinder at higher boost levels (more pressure = more heat). Which is why if you run an E30 equivalent, your octane level is high enough that it can eliminate ‘knocking’, aka pre-detonation, even at the higher boost levels permitted by your Stage X tune. And even this is an oversimplification as your ECU can (and will) adjust a multitude of other factors that can affect knock, including timing of the spark and further adjustments of the fuel to air ratio. One other thing I would strongly recommend if you’re running higher than stock boost levels is investing in colder spark plugs. The poster didn’t mention it but it will help prevent knock as well and deliver better and more consistent performance. Hope that helps make better sense of the video.

[@InlineSixAuto]

Thanks for the extremely detailed explanation of what running E85 does. Also I did mentioned how you should test the E85 using the process I explained at 12:19. And you're right I should of mentioned how you should change the spark plugs to colder plugs. I actually did switch mine to NGK 1 Step colder spark plugs along with my ignition coils to Eldor before running the stage 2 E30 map.

[@F1FanCanuck]

@@InlineSixAuto - yep… you provided an excellent discussion how to measure the alcohol content of the fuel. I thought that was really well done. I just wanted to make sure people knew you can’t assume the same ratio will work each time you go to the pump, simply because the ethanol content of E85 is so unpredictable and can change without notice.

[@michaelbrooks9462]

You can get better results with cleaner power no e85 mixing. Skip the intake as they are not going do that much and like he said cause issues. Get your self the 2.0 bar sensor off the n20 engine. Upgrade the charge pipe, add catch can. And get water meth injection kit they can look very stealthy and use the wiper fluid tanks. You should upgrade the water pump to metal one. And go with a 2 degree cooler thermostat. Two step cooler plugs and use the plugs from the f80 m3. And high flow cat is a must. Upgraded intercooler. I would highly recommend with going with Amsoil racing 5w 50 oil but those mods and coding in BMW track mode. It has the water pump come on early and stay on longer. But with those mods and a great tune you can get to 500 whp. But after that. You have to look at the internals and this is an advanced mod but upgrade the exhaust side cams with ones from an N52 motor. And very overlooked is adding a vent tube for the front and rear Diff and flashing the trans. Because if you don’t do that and keep on the fluids it will break down faster and fail under that extra load. And as coils go I know of guys using Audi R8 coils on their engines as they are smart coils and you get the option for more tuning.

[@InlineSixAuto]

Thanks for the very detailed info. Though I think doing all that would be too complicated for the average BMW enthusiast. Seems like you have a way better understanding of engine tuning/modifying than me and most other people lol.

[@michaelbrooks9462]

@@kmassiah6221 So for the water meth you need to spray it right at the turbo inlet for be the best results for air cool and density you can do this to advoid needing E85. you will need a tune for the water meth injection. I am not a a tuner Stay away from JB4 its trash. but few companies are making top mount kits for this motor. when I go with that i am looking to take some parts off a crashed s55 car. But 550 to the wheels is somthing you can make safely before you need to upgrade bearings and pistions and get the heads worked and flowed and custtom exhuast. And go crazy on the fueling. and that point you should just go forged internals so you could push 700 hp with E85.

intakes help with power yes, from the factory the intake SHOULD only be enough or might not even be enough for your engine to fully breathe and produce high amounts of power especially in cars that are produced from factory with less than 400bhp. if you are going to be tuning your car an intake is not skippable.

BTW - great tasteful build and the exhaust sound is absolutely spot-on. Overall, the whole project was really well done and thought out. Shows what can be done when you start with a solid car and make some smart mods. I’m planning almost exactly the same (power train/exhaust) mods for mine this summer.

Overall people were saying BM3 doesn’t really have any affect or made the transmission shifts feel worse, while there is nothing but positive feedback from xHP and it was no different for me.

MHD works with iOS also. I use my iphone

[@S58PSHIFTING]

Yea i got more in my N55 for less than that, so it all depends what choices you make in parts and tuning.

@@S58PSHIFTING 400hp is not 400whp, these cars have almost 20% drivetrain loss so your car made ~330-340whp

The Charge pipe on the N55 brakes due to it being Flexes, not pressure!

[@InlineSixAuto]

flexes?

[@elipiz9930]

I think he meant the actual material (plastic) flexes from the pressure thus breaking it. A must upgrade any n55. Mine broke and the car was stock, but I did code it with Beamer code

New to modding. I’m looking for a 435i and wanted to have it push 400whp. my question is is 400whp close or at the potential of the N55 engine? i know each engine stock can put out some more power. I just don’t want the engine or turbo breaking. Like i said new to modding so i’m not sure how much extra power would make an engine or turbo break or something. any info is appreciated :) TIA 👍

[@InlineSixAuto]

Based on my personal experience and research with my N55, 400whp is still not anywhere near the limit of the stock turbo or the engine. I've seen a couple people achieve near 500whp on the stock turbo and near 600whp with the stock engine internals. However, once you pass 500whp that's when your chances of blowing your engine increase and you should expect something to break in the engine. For the turbo, I'd say 480whp-500whp is the max for the stock turbo. You should upgrade to aftermarket turbos if you want to go past 500whp. 400whp is plenty of power and allows you to maintain reliability for the most part. You could easily daily with 400whp on the N55. I've been pretty much using my F30 as a daily with 400whp for the past 9 months and haven't had any issues at all relating to the engine itself or the turbo. Still a short amount of time I'd say. But I also don't race people or push the car all the time going full throttle so it also depends on that.

Is this pretty much the same with 535i? Since they both have the n55?

[@InlineSixAuto]

Yes all these apply to the 535i also

[@carlyletom301]

So 400 whp should be 430 at the crank?

[@InlineSixAuto]

Yep around 420-430

[@uthonias]

dumb question but since I dont have E85 in my area.. can I just flash it with E91/93 tune (idc if its not 400whp, anything is better than stock)

[@InlineSixAuto]

Yes bootmod3 has an OTS map for 91/93 octane fuel. It’ll give you around 360whp.

[@HunterRay710]

good ol 85% corn fuel baby usaully its like 70% tho

You can adjust it to have less burbles or no burbles in bootmod3.

[@ganuv]

The best way is get rid of the n55 and go for the b58. Lol

[@InlineSixAuto]

I would agree, but 340i’s are still too expensive for most people. The N55 still offers plenty of power and reliability. But yes B58 > N55
