what octane boosters are effective in n54

[bmw335ie90]

Hi i was just wondering what you guys use to boost your octane in a n54 motor besides Ethanol.

I have heard about OB1 or something like that. How does it work? And is it better for your fuel lines then Ethanol?

Also were is the best place to buy some good Ethanol in cape town and what does it cost??

I used NF Ultra consistently, mostly with a combination of ethanol.
It does make a difference, but difference depends on your state of tune.
If you are on stock tune the difference is minimal. The power gains ramps up the more heavily tuned the vehicle is (if you have the mods to support it).

Eth shouldn't do any damage to your car. I have heard stories about NF ultra damaging plugs but I have never experienced it personally.

If I had to choose another octane booster other than NF, I would most likely use 24/7 Race fuels.

I have only ever used UCBRacing Performance Fuels (Napalm and Thermite) or Ethanol in my car.

Never had any issues.

The car will be FBO + inlets. So i want to gain allot of power with higher octane.
Everyone seems to use something different. How does nf ultra work and why does it hurt your plugs?
As well as were can you buy goodeth for a good price. One local guy is asking R400 for 20l.

Below is a list of SOME of the octane boosters that have been on the market for ages. NF ultra (silver bottle) seems to be the best bang for buck in term of Ron increase.

Ethonal is brilliant for making Power, and is most n54 users fuel of choice when required.

Thanks allot that chart really helps!
So on a stock feul pump most guys only run a e30
Can i run e30 with The NF ultra? Or will it damage the pump somehow?

NF Ultra also worked the best for me and easiest to use (don't spill it!!!!!!). OB1 was OK, but you need to add a lot to a tank, like 10l if I remember correctly.
Most guys seem to prefer eth with upgraded fuel pumps.
You going to maybe try run 50/50 water/meth? That seems really bang for you bucks.
Athlone Midas stocks some good fuel additive options.

 

[FiRi@Rennzport]

E30 and nf will work well. Log and then review the logs. If hpfp and lpfp are still within parameter, then up the eth. A stock lpfp should handle e40 easily

 

[individj]

you guys referring to NF Ultra Unleaded Race Fuel Concentrate 1L?

 

[MLGCUP177]

I have tried the following on my G5 GTI BT:

ethanol 5l to 20l pump 95- cost effective works well for every fill, fill more often though

OB1 5l to 20l pump 95- better than eth alone but gets expensive, fill more often

Nf ultra silver can to 40 litres pump 95- best octance so far on 2 bar no timing pull on my G5 BT- fill every second week, i hate refueling all the time so i use this option now, my plugs seem fine too.

On my M135i just run pump fuel never tried octane.

My car is a lot happier with just eth but I’ve noticed that filling up with eth the day before makes a bit more difference.

Sweet so NF ultra is the way to go it seems.
I have been thinking about the watermeth idea but im to clued up on that. Can someone explain it a bit better?

As far as i understand it, the meth gets injected into the intake (mostly some guys do each cylinder but i heard its more risky and not easy to install) and you need to have a tank were the meth can be kept most guys do it in the boot. So the meth comes in at a certant psi of boost that you can adjust on tunes like mhd. Its a very cold liquid that drops the intake temps to near 0. And that makes the air more dense so it has a higher amount of oxygen and therefore makes a bigger combustion inside the engine and better timing because you run colder. And that makes more power from a stronger map. Is it true that it ups your octane aswell? Just what some guy told me don't know how true it is. How safe is it to run meth with mhd? Please don't judge i have not read up about it. So i am asking for advice you guys know allot more then me. And i need to learn:rollsmile:

So how is the OB1 better than eth alone? And how is it better? Does it make more power than eth if you mix both the same ratio use 5l to 20l 95.
Your 135i will love it.

Water/Meth cools the charge air, increases octane some say to 104 level and suppress knock, etc. It won’t drop your intake temps to Zero, I’ve never seen logs with zero IAT’s
Its best controlled by a JB4 and FSB controller. You can setup the amount of boost you want to target, at what psi meth comes in, etc via the JB4.
The BMS Race Flash is best suited for Meth. But some use meth with a pump flash.
The install can be challenging if you are doing it for the first time. Best to get someone experienced to do the install.
The tank should always be installed above the pump as the pump is gravity fed and away from direct sun light and heat.

Thanks man so i was almost right.
104 is allot higher, seems much cheaper than using ethanol all the time.
What brand meth kits are best?
And what are the chances of meth going wrong??
So jb4 and bms race flash combo would be best.
How does meth compare to e40 ethanol.
why do some people mix the water meth with water if meth is so cheap?

There a few out there AEM, Snow Performance, Cooling Mist, Etc. All work on the same principle but with different features.

And what are the chances of meth going wrong??

Plenty can go wrong, if the install and setup is not done correctly, you basically asking for trouble if you don't know what you are doing..

So jb4 and bms race flash combo would be best.

Thats what i prefer, the Race Flash has more timing added to it than the BMS pump flash which does require better fuel to take advantage of it, that were the Meth octane increase comes in. Also the Meth Safety features on the JB come in handy.

How does meth compare to e40 ethanol.

I've noticed alot more kick with Meth than with Ethonol alone.

why do some people mix the water meth with water if meth is so cheap?

Meth is very very very flammable. You will not even notice notice meth burning, adding some water to the mix makes it less flammable. Water also plays a key role in cooling your intake charge

Thanks so much man. That really clears things up for me. And the effort you put in is much appreciated! So if the install is done at a professional shop and i use jb4 with bms race flash i should be safe???

What happens if your meth runs up while you are driving and you are running a map with more timing?? How long does a 1l meth normaly last? 1000Kms? Does jb4 map 5 work with meth?

Do you sell it at R299?

The likelihood of something going wrong would be minimized. But one thing is for sure, is when you modify your car, you are pushing beyond what your car has been designed for, modifications will always find weak points on your car that you will need to be taken care of. No one will 100% guarantee safety as each car is different. You need to decide the amount of risk you want to take

What happens if your meth runs up while you are driving and you are running a map with more timing??

If you run out of meth and you have the proper safety features in place it should not be an issue. I run the race back end flash as its a sort of hybrid flash that can be used with just pump fuel.

How long does a 1l meth normaly last? 1000Kms?

3l will only give you about 10 good 3rd gears pulls:roflol:


Does jb4 map 5 work with meth?

Yepp you can run meth on map 5

Thanks man now i know a bit about meth.

Wow then it does not last as long as i was told.

Im leaning towards ethanol. As it seems to be the safer option.

Since you only get like 10 WOT pulls with 3l of meth. i might as well just use eth and change my fuel pump. Higher octane rating also on a e60 mix.

Thanks for all the help!
