Swaps, Turbos, Buildups / Martins Twin Screw Supercharger Build

« on: December 12, 2011, 11:34:24 AM »

Wazzu70, you are local. Maybe you will have to check it out sometime when i get it going, or in the car.

I see both of you are in this part of the country! I would love to see/hear/feel how this supercharger pairs with a M42, I would love to Supercharge my E30 at some point in time.

Sorry for the OT following this, I will remove if requested by OP:

Wazzu70 are you a current student? I am attending WSU right now, CE... We have a local BMW group that often gets together to talk/eat/gawk/photograph with one another... Our pro photographer just graduated on Saturday so he will be leaving us in a couple months although his parents live here, I got some great photos from him though!!

Both of you, Wazzu70 and bbarnumboy should join this local club: NWBMWClub.com; it covers WA/OR/ID/MT. Basically a great group of guys that are always interested in awesome projects such as the OP!

Engine + Driveline / Mustang Injectors in an M42 engine

« on: July 10, 2011, 10:10:03 PM »

Installed 0280155710 injectors in my E30 today... I noticed two things which I am slightly worried about. First being that these injectors are noisy! You don't hear them so much when your in the car driving, but when you are sitting over the engine bay they are loud. One more thing, not sure if it is related at all, but there is this noise coming from the timing area that sounds like a couple marbles knocking around... I noticed these noise slightly when I had my old injectors in (one injector was bad and NOISY!), and after driving the car hard the noise had amplified... I drove the car several times later after this and there were no other noises that were of concern, which has me wondering what is up.

Do you think I need to increase the fuel pressure? Possibly restrict the return line slightly to do so, or what is the best way?

Hopefully I get a good mileage increase.

Engine + Driveline / What is your oil pressure? ('91 E30 M42)

« on: May 30, 2011, 04:43:44 PM »

I think most people don't know because it takes seemingly invasive modifications to measure the pressure. Did you put some sort of Tee fitting in where the pressure switch is?

There's a spacial BMW tool out there for this that is basically a hollowed out filter lid bolt that has a gauge on it. That's the only "factory-looking" method I've seen to measure oil pressure.

I seem to recall reading 60psi as the oil pressure at red line RPM with 20W-50 oil.

When it comes to a 318iS I am not keen on keeping it factory, its my go-cart so oil pressure is an important modification in my books... I would keep an E30 M3 factory.

I, with help from my father, machined an aluminum block to accept the stock metric fittings to convert it to a stock fitting for the dummy light then another for the standard fitting found on the after-market sending unit.

Here are some pictures of the finished product.

I was watching this mate as I have just got a pressure gauge and was wondering what it would run at.

So what is it running at

Oil pressure at a warm idle was around 18 PSI, according to the precision gauge I had a pressure of about 15 PSI but I think this is due to my car being slightly warmer on that test...

When I took the car out to test my new set-up I reached a maximum of 59 PSI which probably took place around 5,000 RPM...

According to the Bentley manual the minimum pressure at an Idle should be 9 PSI, and driving hard around 60-66 PSI, so I am in the ballpark, which is good piece of mind.

I just spent a good amount of time creating a response to yours' questions and I get a stupid message saying it needs to be approved by a moderator... Why is this?

Could it because of the photos, using external links to this post? This happened earlier when I was trying to link to another thread on this site.

I will try again.

carlos318is, my car was running around a 18 PSI idle, although it could have probably been warmer. When I tested it with a very precise gauge it was reading 14 with a really good warm motor. When I drove the car hard, didn't hit red line on my test, I reached 59 PSI, which is on par.

According to the Bentley manual the M42 should have a minimum idle of 9 PSI, and 60-66 PSI under very spirited driving.

I am running Fully Synthetic (Mobile 1) 10W-30 oil also.

bmwman91, with some help I machined an aluminum block that had an input using the stock oil fittings to one output using the stock threading, and then another one using a Standard thread to accompany my after market sending unit. This was a costly task as I had to buy several fittings for my oil pressure cable, which they are not cheap at all...

Here are a few pictures I snapped with my camera just as a reference in case anyone else is wondering what I am talking about.

Well, no help here...

I got it figured out though, needed a better ground to the sender. Hooked up a very accurate oil pressure gauge and saw I was not close to what it was really at, so I jumped the sender to the body and found that it was reading wrong the whole time, which I figured. Disappointed in the lack of help on this forum, I find it hard to believe people do not know their pressures...

Doing this right now... http://www.m42club.com/forums/showthread.php?t=594

Figured its not a difficult job, might as well check it out. Car is coming up on an oil change soon, 500 miles...

I just finished installing an oil pressure gauge, digital. After machining some parts to hook up both my dummy light and my gauge, I finally have a working gauge, although... I think its off with my pressures...

So at a warm idle, it reads 8-9 PSI (~700 rpm idle)... It was actually reading below 5 once, which then it just reads LO... When I have my car at 6000+ rpm it reads just over 40... My engine runs amazingly, and these pressures just seem way to low to be true... Was just wondering what a healthy M42 should have for oil pressure, warm, at different RPMs...

Thanks,

Idle will improve, and i will report back on mileage gains.  As for the injectors not ticking haha.....umm these things tick way louder than my old stock ones do. But it does not bother me.

Sounds good man looking forward to hearing more from you. As far as a tick goes.. I have a BAD injector, needs some cleaning most likely so it is LOUD, haha.

yes those are the correct injects,you can ask the people on rev-limited  website.

Thanks bro, I'll take your word for it. Cannot wait to get rid of my old ticking ones. Also looking forward to seeing if their is any difference in feel. I have read that the mileage may improve slightly but that it idles more smoothly. Worth $100 IMO.
