Any meth users here still active? Was it worth it? I had meth on my 340i and I loved it, but I'm running E50-E60 on my 335is and I'm not sure if meth is necessary, but I am looking for cooler intake temps and more power.

Current Mods:
2" inlets
K4TL3SS PIP3S
DCI
Stage 2 fuel pump
PR coils
Intercooler
MHD custom tuned

Meth is always worth it. Be it in your lungs or the lungs of your car.

Which kit are you running?

You want cooler temps? Then run meth
You want more power? Then run meth. More meth allows more boost, more timing and more fuel.

There's a reason the fastest cars bar nitro cars run pure meth and they dont even use intercoolers

i'm running meth port injected, snow performance system with BMS manifold and ported rail

I ordered the Snow Performance Stage 2.5 yesterday. Now I'm deciding if I should run 100% meth or stick to a simple 50-50 mixture.

I'm running 100% meth and i love it ! do you the kit with the plate that comes between engine and manifold ?

No since I run a E50/E60 ethanal blend I got the kit that sprays through the charge pipe. I'm going to run dual CM5 nozzles and upgrade to dual CM7 nozzles later when I swap out the turbos.

I ran 100% meth on my 340i, but do you think its necessary on the N54? I was thinking about 50-50 or at least a 70-30 mix.

I'm not an expert but I've been running meth on both N-A cars and boosted for some time. 100% meth is OK in cooler weather, if there's any temperature, there's an advantage to running between a 50/50 to 75/25. Water is better at removing heat than Meth. If you do run 100% that means much more Octane so you have to tune accordingly. It's a balance and if you have the ability to log, then that's the tell tale of how much or not to run.

I will most likely end up doing a 75/25 or 70/30 mix. I do want a little more octane, but also have the ability to also cool off the intake temps a little better then just running straight 100% meth.

Does anyone know the nozzle size of 250cc, 500cc, and 1000cc is equivalent to the BMS BM nozzle? The AEM kit I got has those 3 options, but I'm not sure what size I need.

AWDGT2 · 11-05-2020, 07:03 PM

The math is fuzzy because you have to convert cc flow to GPH, but.. 1000cc would roughly be a #15, 500cc is a hair over a #7, and a 250cc is about a #3 or 3GPH

I got the meth kit installed. It's progressive and we all know the 10 psi starting point is great, but for full spray what's recommended? I also ended up running the BMS single BM10 nozzle.

Have you noticed an increase in power when running the BM10 nozzle on E50? What meth percentage did you use?

After getting some adjustments made by my tuner I did notice a big gain of power the more it's being tweaked around and what helps the most is the HPFP is even happier since the trims stay higher from that extra meth fuel. I'm running a 80% meth mix with 20% distilled water and I have the controller set to full spray at 10 psi with the single BM10 nozzle.
