And another for good measure.

Well I'm glad this got so much attention in my absence.

@Jimmy: These are just the building blocks. Standalone is in the future as well as a complete overhaul of another m42 for more boost.

But, think what you want. I do appreciate your help.

Don't worry, I'm down with the brown. I would love to see you get some kind of megasquirt setup going after you get it running on the reg. I just think your "aura" over on r3v gets my panties into a bunch. Shit if you lived around my parts we would probably be buddies. Get this bitch running right, don't grenade it, and take what you learned and do a proper build down the road. I just like poking fun, no harm, no foul.

you always gotta learn somehow. as long as each build/attempt is improved upon and you learn from mistakes, you're on the right track. keep wrenching and things will continue to come together better and better.

Mostly this was to shut up the usual BMW owners that have to have everything bolt on and aren't able to fab things. Once it runs good on the RRFPR, megasquirt will be bought.

One thing I learned, don't waste your time making your own gaskets with gasket material and copper spray.

Get the right shit.

Ok so there is a weird sound when I'm under boost at high rpms.

It sounds almost like little rocks going through the intake or hitting the fender.

Any ideas?

Danny707 · « **Reply #172 on:** January 30, 2009, 12:32:57 AM »

It idles fine but it drops and picks back up everyonce in a while due to the richness.

I just went out and drove it again and it seems to be coming from behind me.

Almost like an exhaust leak.

Its definitely not from the intake or motor.

Also it only happens sometimes.

Even though its coming from behind me?

Not from the engine bay?

I hope your running cooler plug's from stock...The nice thing about the m42 is when you hit pre det it's very noticeable and you can realy feel the power loss and realy realy hear it...unless you have both those symtoms I would start looking for exhuast leaks witch can be mistaken for knock

nomad · « **Reply #176 on:** January 30, 2009, 08:51:15 AM »

That sounds like det to me.
The sound waves can bounce off of things and seem to "appear" in many places.

Its hard to reproduce certain things parked, under boost, under load, at speed and then they appear. Maybe check on the tuning a bit? Boost creep? Need more fuel pressure? Colder plugs?

I'm interested in these things you run into. Keep up the hard work.

Тry to reduce the thickness between spark elektrodes ,thickness must be 0,5mm for boosted engine.

tglaze · « **Reply #178 on:** January 30, 2009, 07:06:53 PM »

what is your air fule ratio under boost?

this is the spark plug you want. we use it for most of our higher compression bmw boosted stuff

ngk r5671a7

i can send you some if you cant find them localy.

bearsbmw · « **Reply #179 on:** January 30, 2009, 07:52:41 PM »

I use NGK R5671A-8
The only draw back on these plug's are that they cause radio interferance and so you must get resistor plug cap's or a ground loop isolator

this is where I get mine http://www.carshopinc.com/advanced_search_result.php?keywords=+R5671A-8
