Yes that was my case, hence I mentioned smaller. If you guys run smaller pulley than one originally from ESS then yes, but over stock it's shorter and better and feel stiffer too. ESS never offered a smaller, correct, and custom deal you did right?

Right, I used a chart to determine the size belt I needed for the 110mm pulley.

Did you do a custom tune, or leave ESS tune? Also, noticed a big difference? Thanks man

Worked with the same shop as minutes2midnight. Bob Bishop at stage FP is the man when it comes to providing custom tunes, especially on the N52 ESS kit. I put down 303 on the 93 tune and 331 on the e50 tune awhp on an x drive 328i e91.

Got ya, those are great numbers. Did you ever dyno on stock ESS tune, just curious. Thanks

No I bought the kit used so never had an OTS tune from them.

Anyone in here running meth yet? What kit did you go with? I am lookin lookin. But I am unsure if I should just snatch the stage 2 from snow performance. Also unsure if I am supposed to just use the nozzles that come with the kit or if I am supposed to obtain a different set for this application.

Speaking with Bob — waiting for information from a seller for a motor off eBay. Homework time is practically done. Going to get back on the saddle soon.

1st dump the damn car and forget about the n52. You could of had a 700whp n54 by now with the money you have spent. Instead you are still well below 400whp.


Now knowing you are going to ignore that advice, I know more about meth then I ever wanted to. I can help you size your jets correctly.

1st choose what you will run 100% meth or 50/50 WMI?

Choosing water/methanol flow for your application:

100% water: 10-15% water/fuel ratio or 0-5-1cc per BHP
M50/W50: 15-20% MW/fuel ratio or 1-1.5cc per BHP
100% methanol: 20-25% methanol/fuel ratio or 1.5-2cc per BHP

BHP or crank HP. Let's say your aim is 350whp. Assuming a 15% difference from whp to chp/bhp puts you at basically 400 BHP.

Assuming you will use 100% meth that is 600-800 CC you need to inject.

You will want to use 2 nozzles vs. 1 for better atomization. Have them 180 degrees from each other in the CP for best distribution.

Ok so now you know how much to inject. But we have to compensate for the amount of boost you run. How much peak boost do you run? Then we can continue this exercise.

Torgus you are a well of immense knowledge
My head hurts
I have not slept
Right now only 10 pounds of boost
Hopefully anywhere from 15 to 20 pounds safely after cooling measures are added

Sorry I was away on vaca.

Ok so now we know the boost!


A constant line pressure (160 psi) is provided by an Aquatec pump working
in the “by-pass” mode. This is the red line.

Now subtract your boost, in this case let's use 20 psi. So now you are on the 140 line.

Last time we arrived with using 100% meth that means you need 600-800 CC of meth.

You will need to add 10% for pumping losses through the system. Some people do this, some don't. Your numbers slightly change to 660-880cc.

We want two nozzles or jets. Ideally 2x 330 or 2x 440.

Go up the 140 psi line. The 0.6mm blue line hits 330 perfectly. 0.8mm hits 440 on the dot. It usually is not that perfect.

You may or may not want to use a check ball style jet or nozzle like this: http://www.aquamist-direct.com/806-5...-applications/


I like aquamist. This is how it compares to others:


Use whatever works best for you. I would recommend you get a meth kit with as many safeties built in as possible.

Taking mine down for a custom tune/dyno setup in a couple of weeks. He said mid range has lots to gain and sone up high, excited to see.

Will keep you posted on before/after etc!

Cheers guys!

I completely forgot about aquamist until you mentioned them! Thanks brother. I would've just defaulted to snow if you didn't add this sheet and speak of fail safes, I owe you one.

Got in touch with Ghassan motors. Cool stuff on that front... Bob is working on some cool stuff, too.
About to start the process on obtaining my first home (woohoo I'm Fkn stressed). Progress will be slow, but it will be made.

Be careful with Ghassan. They have a bad reputation on the M forums. I’ve seen a few threads complaining about them.

I agree 100%

Lots of questionable threads on them on many platforms.

Also this is the owner: https://www.stwnewspress.com/news/st...4b560ca11.html

How at 26 do you own a shop like that building performance engines and having a ton of lifts? Something does not add up. I don't want a 26 year old making those decisions.

I would not build an n52 up. No need to in all honesty with that SC. Cost would be the same if not more than to build an n54 and be able to handle 2x the power.

Oof I'm glad y'all showed me this. Thanks lmao fffffuck.

I only wanted them to really just put in fancy pistons with thicker rings tbh. It's hard finding a low-ish mileage n52 engine that isn't 1500 bucks before shipping. 🙄

What pulley came stock?! Drawing a massive blank. 115 right? While I'm waiting, I am trying to get a nice lil refresh shopping list going for whatever engine I snag. Definitely want to see if there's any difference with the belt...

Edit: just kidding guys. My kit literally came with a 120mm lmaooooo. I went back and looked at the google drive I shared with all the detailed pics. Bruh. Everyone else is running 115s and 110s?! WAT

I am on stock one, so bigger I assume. Heading in for dyno tune on the 18th, let's see! Boom

[Minutes2Midnight]

Just wanted to let you guys know that the conti belt y'all recommended fits the 110mm pulley perfectly and fixed all of my slipping issues!

Awesome!! Glad that fixed it, sorry the one provided slipped.
