They are offering N52 supercharger upgrade kits.

They are promising up to 400whp with the stage 3 kit, it comes with:

· Tune

· Smaller pulley ~12-14PSI (3.4 inch)

· Matching belt

· Spark plugs

· Upgraded idler pulley kit

· Meth kit

· Billet Gauge pod

Cost: $2000 USD

On top of this price you will also need an N54 intake, an exhaust, and the meth itself.

Question is, for those making 400whp currently, is this price reasonable? Can this number be achieved for less sourcing the parts and tune from elsewhere?

This puts the spend for 400whp at:

- ESS Gen 3 kit $4795
- 22RPD Stage 3: $2000
- N54 Intake - $100 approx
- Exhaust - $1100 appox
- Labour: $1400

Total: $9395 approx before shipping, customs

Forced induction sure ain't cheap, any money to be saved there or is this the general expected spend?

10k seems crazy for 175whp peak gain. You could have someone custom make a turbo kit for less and make more HP/TQ. You could LS swap it for less, you could ls swap and turbo for less. You could sell your car, buy a 335i, and make more HP for less money.

Does not seem like a good deal to me. Now if you already have a SC'd n52, sure, as it is your only option for more HP and they have done all the 'work' for you.

I think we generally make about 180 at the wheels stock so it'd be for around 220whp gain. Still not a great deal honestly speaking. Definitely passion project type numbers.

That low?

I found most stock dynojet numbers 210-220whp peak:

According to wikipedia the n52 in the 2007-2013 E90/E92/E93 330i, 330xi made 268 bhp. 268 *.83 for drivetrain loss comes out to 222whp.


Either way 10k for 400whp in this day and age is cray cray.

Forgot to mention that I’m referring to AWHP from a video I saw a while back.

I referenced this video today to check for rwd cars:

https://m.youtube.com/watch?v=PxkyZFIZ9to&pp=ygUTMzI4eGkgYmFzZWxpbmUgZHl ubw%3D%3D

Low 190’s for WHP, there can always be some variance but 220whp on a stock N52 seems high. In the end all that really matters to me is the power my car makes so hopefully I find time to pull the trigger on a baseline dyno soon. Seems Wikipedia had an optimistic author on that article, maybe I’ll edit it.

Good news is 4N motorsports has released a mock up of an N52 bottom mount kit and they are promising 450whp on a stock engine (more with a built engine). Waiting to see some dyno numbers but I’ll concede they the company has managed to produce reliable track tested bottom mount kits for the N54, N55 and S55 engines thus far.

As long as the block can hold the power I see no reason why an N52 could not make 450whp on 93. Now you may need fueling upgrades etc. to get there.

The 4N kit looks nice but there stuff is expensive! I am surprised they don't just use a simple log style manifold. You don't need that tubular manifold for 450whp. Hell you could make 800whp out of a log style if you wanted. It does look very nice.

I have seen very few 4N kits on N54s fwiw. For their cost I would buy the CES n54 bottom mount kit with the steedspeed manifold.

I Agree, with Stockish setup and this with required upgrades you bump over 200+ WHP, which is pretty solid to remain durable with non-forged internals. I woulld not go past oem redline though, especially as you already make good power. Could I make 50 wheel more, obsolutely, but I want things to last. Btw, still only up to 0.75 quart oil burn over my 5k interval and I have plenty of fun without being stupid with it/drastically increase wear.

Just did an oil and supercharger fluid change at 185k miles and running amazing, Driven DT 40, and typ vortech fluid.

Cheers guys, and don’t cheap on maintenance, it will catch up with you, but if you do it’s rock solid and see no reason I won’t get to 250k+ Miles’s before engine rebuild at current state w 400 whp and such a fun car.

[Igor.v_a]

I measured the power on the dyno and it is 327 hp at 6466 prm and 377 Nm.
It was not possible to measure up to the end, we ran into the maximum speed limiter.
I want to emphasize that I use only gasoline 98 ron euro (93 ron usa) I do not have E85 or water methanol.
My car configuration is as follows:
Engine N52B30
Supercharger ESS Gen 3
Intake manifold N52 stage3
Porsche 911 GT2 Injectors
Pulley 100 mm
Setting 22RPD

Hello, this is my first post so I figured I'd jump in. I have the Esstuning supercharger as well on my e90 328xi and found this thread while kicking the idea of running the 110 mm pulley down from 120mm and the proper belt (found part # in this thread) .

Emails responses from Esstuning state the system software can handle up to 330 whp but also goes on to say it can't do over 6psi on 93 octane safely. And they "left no safe hp on the table"...which according to a few of you fine fellows that seems to not be the case.

I'm really about ready to just pull the trigger on the pulley belt and just jump on. Right now the car is 100% stock save for the blower kit from esstuning, window tint, dif side indicators and front lip thingy. I'd be happy to hit 300 whp honestly.

So in a nut shell
G1 blower @6 psi 120 mm pulley
S65 injectors
Esstuning tune
Gm auto 6 speed
Boost gauge I've been too lazy to install /vent mount setup

Noir Was there anything you had to modify in order for the vargas n54 spline hub to work? I'm asking because I'm going through the same issue of having my motor going out of time. I just retimed it for the second time, but I don't think it's going to hold together, but I don't think anything internal got hurt from it.

Also just to make sure is this the exact kit you bought "https://vargasturbo.com/product/vtt-n54-spline-lock-crankhub-solution/" because everywhere I looked it says it isn't compatible.

Also when you installed it did you end up pulling the oil pan, or were you able to do it without pulling it off?

This happened to me twice.
Camshaft - crankshaft: synchronization.
I removed 7500 prm.
Now I did 7000 prm.
We screwed the crankshaft bolt onto the thread lock, we also installed a washer from N54 for the timing star. N52, no washer near the timing star
I also bought a new crankshaft vibration damper, the old one was crooked and possibly at high speeds, unscrewed the crankshaft bolt.
Now everything works well.

Hello.
Tell me, please, do you have exactly such a water methanol injection kit, like in the photo?

[Seattlesquash]

Yes, thats the one I have. On other car I have the aquamist controller -4 which I prefer, but snow been working great just prefer the other one I have in other car so if I did it again I switch. It’s more advanced and has more control options and gauge a bit better looking. But in general meth been great for my supercharged applications, in BMW I just run it without intercooler and freestanding cooling system, and in Audi combined with IC/independent cooling system.

[Seattlesquash]

Thinking about it, I thonk I have the stage 2.5 but surely very similar.

Where in the cabin of the Bmw E92, did you install the control controller (round with buttons)?
Attach a photo

[dmytro98]

So since I've had the splined crankhub installed, it appears my timing issue is fixed but I'm still having issues. The main issue is sometimes the car pulls amazingly but most of the time it just feels like it's lacking power, and sometimes just fully cuts out and feels like it's hitting a limiter after shifting. There isn't anything consistent that I've found that causes it to pull well or not, just seems to be random. I attached some logs, but I have no clue what I'm looking at.

I already have 997 gt2 injectors

Show a photo of the crankhub you installed.
There is no crankhub for the N52 motor.

[dmytro98]

The crank hub I got wasn't meant for the n52. It said it would only fit the n54 but all I needed to change to make it work on the n52 was using an n54 oil pump sprocket that the crankhub slips into as it was different sizes. Everything is shared between the n52 and n54.

The one on the left is the original crankhub, and the one on the right with the splines is the VTT n54 splined crankhub

[l0gg3r]

Do you have fuel pressure sensor installed?

Try logging that as well, maybe you’ll need fuel pump upgrade

I didn't know I could add a fuel pressure sensor to the stock ecu, because I know for the n52 it uses a fuel pressure switch

I have a 100mm pulley
Gasoline 100RON (EURO)
Porsche Injectors
Setting 22RPD
The result is 327 whp and 377 Nm.
I find this to be an excellent result using only gasoline.

[l0gg3r]

you need to wire it to external gauge/display

DSC can do that too. I have noticed DSC can allow a lot of slip and when the slip stops during gear change it starts to "catch up" to situation and after releasing of clutch there is no engine power available until it gradually allows more engine power.

There is something wrong with slip integration in DSC as it acts after gear change. I assume DSC integrates quickly decending wheel speed to calculated wheel slip value. Or maybe it has a thing where it let's a lot of slip occur in low gears, but doesn't reset integrator during gear change.
