awesome. btw gizmo, what have you done about the vibration damper? apparently they can sheer the nose off the crank at 7,200 rpm
E36 and E46 only!
Currently my rev limiter is set at 6800rpm. Once the cams+ITBs setup is in then I will spin her to +-7500rpm.
As for the damper, I have a spare damper that I must inspect and see what the big deal about the thing is, probably get a machine shop to built me a new solid billet aluminium one.

Amazing. I'll admit I was wondering if this was actually going to happen, but you've made a believer out of me. I can't wait to see the dyno charts for this thing once it gets tuned.
I call BS - there's no bmw driver that can't run his car faster than any magazine has ever done before.

well thats an interesting factoid I didn't know about S.A.Originally Posted by Gizmo318i
I have 1000km's so far. I have the M3 300cc injectors in there with the std ECU, just played around with the adjustment screw on the AFM.
My car doesn't have a lamda sensor, never came with one. In South Africa we still have leaded fuel,
until Jan 2006 when it gets phased out...
gizmo or any1 whats the cc on stock M42 injectors?
also the AFM sdjust screws, this the 2 scrrews on the vane/flap inside the afm?
whats adjusting it do? control idle?

must admit i find all the hype over the vibration damper quite intriguing. have a spare m42 on its way to me soon which i'll take a look at. figure a solid pulley will probably resolve the issue, but want a better understanding of the purpose and problems associated with the pulley in the first place.
Spec e30 FTW!
I accidentally spun mine to about 8600 for a few seconds. It wasn't running smoothly, however, the only problem was the power steering pump running too fast and blowing a hose.
Needs more downforce
Do you know how high you could go with different valve springs + retainers on your setup this spring? What exactly is the problem with the damper? Does it just fall apart at high speeds or what?

I've got to say that this is the most informative thread on the buildup of the M42/44 engine I have ever seen. I look forward to reading it, just to see if anything new is up. Thanks to all who are contributing to the new breed of BMW power. I support your efforts and look forward to the benefits of your trials.
THANKS,
John B.

Im really having fun with this new motor now, its really opening up!
No-one believes me its a 318i any more...
I've had a good couple runs lately, beat a late 1980's 500SL Merc last night, and whipped a Subaru 2.5 RS tonight all the way to topend. I definitely need that 6 speed gbox, my car runs outta legs quickly now (144mph @ 6800rpm, 5th gear)
I managed to get a Euro M3 cluster today but I need to import a module that will make the 6cyl tach work with the 4cyl signal. Gotta get one of these: http://www.dakotadigital.com/index.c...rod/prd127.htm

I don't claim to be an expert on crankshaft harmonics, but I don't think a solid billet v. damper would absorb much vibrations. I would hate to see disaster strike with this unique project...careful with this.

What I want to know is how us over here in the states get ahold of the m47 crank? This all reminds me of the "hybrid" engines I have built for my vw's
Member
Hey Giz, most of us only dreamed on what you just achived but if you have documented what you have done it would be a great help for every one. I would like to ask you personally to share the great M42 project as i have been dreaming of having more power on my 318i.
Thanx a lot,
Member
any updated info on this, anyone have any lines on the m47 cranks?

cant wait for they dyno!

you're probably going to have to order one through BMW (expensive) or find someone in europe or possibly SA that can find you a used one and mail it to you.

raw-foodist
since you want one, ill be nice and trade ya, i just live down the street anyway.
Needs more downforce
You can get the M47 crank from a US dealer for about $800. This is through my local dealer, which is always substantially higher than Pacific or pretty much any other.

Ok, I had my car dyno'ed by Steven at Rob Green Motorsport today. He was VERY impressed!!!
168whp@6000rpm, this is with the stock cams and stock head....The 328i MAF conversion did help alot though...
I should see 200whp with the headwork, big cams and throttle bodies next year...
A stock E36 328i makes around 144whp on RGM's dyno...

wow, you must be well happy! what fuel were you on?
E36 and E46 only!
Pump fuel, 93 leaded.

Those are great numbers, for a N/A motor. I was running 160rwhp at 6.5 psi of boost on TT Stage 2 setup and a DASC. I've got TT Stage 3 setup and a smaller pulley now, running 11 psi. I haven't dynoed yet, so I'm not sure of the gains.
Keep up the work and good luck on the 200 rwhp. Keep us posted.
Before the board went down, a few of us had asked what the chances of getting a crank from you were. Any thoughts if you would be interested in looking into this?
Thanks,
John B.

Looks like I may need to build on of these engines
S54 FTW
What did the S42 motors put to the wheels? Also, wut kind of dyno was this? (144whp seems low for what most 328s dyno at in the US - wondering if you're using a dyno similar to the guy in AU with the 318TI thats turbo'd...)
