It's impressive the Tourqe pulled. Usually you don't get that

[@Dim4ik2012]

sweet. I have m52b20 in my e30 but it definitely needs m54b30. Nice numbers! I'd be happy with 233HP.
We will see how it goes...

Hi, nice result and set up. I have a very similar set up on my 330ci project car. Few questions if I may, how easy was the M50 install? What Gaines did you see? And which adapter kit did you use? And did you match the head? Finally is that power at the wheels or crank? Sorry for all the questions! Thanks

[@Just_A_330ci]

Hi EDP.
You’ll be better looking at my build thread in the link in the descriptions. All details and photos are on there including photos and dyno print outs. Be easier to ask any questions once you’ve seen that. My Instagram is posted on there too if you have anymore questions.

[@eastdevonperformance7432]

Tom B wonderful thanks.

[@UndeadCrook]

Only 15Bhp gains with M50, should be way more. Car stock is 228 with just a tune you can get to 235-240 depends on engine condition. With Exhaust and intake you should be at 260 at least, what afr and ignition advance are you running ?

[@Just_A_330ci]

12.5 AFR in the higher RPM’s with Ignition timing peaking around 30 degrees.

[@noussairmoroccan-tunner]

Hi bro . What is the peak power u get with that mod . ❤

[@tudordan6337]

Hi! 243 with or without a tune,at crank or at wheels? Thanks!

[@Just_A_330ci]

Tudor Dan
Adjustments have been made to the vanos timing on both the inlet and exhaust to get to those figures with the M50 inlet. 243bhp/245ftlbs at the flywheel. All information is in the build thread in the video description. Cheers.

[@anthonyk]

Are the numbers low because of the dyno? I thought this mod added like 30 hp to crank to bump it up to like 260

[@tootses2]

crank

[@dsturbovq]

Did u port the head for the m50 manifold?

[@Just_A_330ci]

I use one of these adaptors to transition between the manifold and the head

Hello there...nice number..
Can you tune my e46 m54B30??

[@acesihatay8703]

Can't be right .. You should be making at least 250 -255

[@TakenSlays]

i saw people get 280 and even a 325 with 220

[@Just_A_330ci]

That’s possible on some dyno’s. But not on this one.

[@eliecharro7229]

HAVE YOU GOT A PROBLEM AT LOWER RPM'S LIKE YOU HIT THE THROTTLE AND YOU GET RESPONSE AFTER LIKE A 0.25 SECONDS AND NOT IMMEDIATELY?

[@Just_A_330ci]

No issues with the set up at all. Works really well.
Check out some of my other videos for it in use, especially on the new engine.

[@claycarbone5607]

That sounds like u got a vacuum leak somewhere

[@eliecharro7229]

@@claycarbone5607 i changed the injectors to mercedes 230 kompresssor injectors bigger than the old ones and now it runs perfectly

[@kingly7946]

@@eliecharro7229 Did you tune after the 230 injection or did the car run better by just swapping the injectors in?
