Problem:

Distributor internally being off 90-180 degrees when under load
Distributor Type: Electronic Style Ignition

Vehicle:

1976 BMW 2002

When it Happens:

The car is only able to be run on the Dyno under a heavy load. This does not mean just revving it up in the driveway.

The first time that it did happen, the can stalled in between 1-2 shifts twice and then when shifting at a higher RPM over 6,000RPM the engine died and would not restart. I checked the timing and it was off 180 degrees, I readjusted it and she started back up.

The second time once again on the Dyno on a different day I did do a granny run to make sure she was running well. On the second run when getting into it right as hitting 6,000+RPM the engine started sounding like gunshots going off . . . it died and wouldn't start up. I went home, once again resetting the timing from being off 90 degrees and she started back up.

Diagnosis:

I called the company after talking to many people about the issue, they all agreed that it was an issue with the dist. After talking to one of the companies representatives we went over all of the basics and then he said without me asking that they would send me a new dist.

Shortly after, I received an email saying to check the magnets in the dist and locktite(sp?) them. So I was taking it apart carefully piece by piece as you see in the pictures and after removing the rotor I saw a piece of plastic on top of the felt on the shaft. I looked inside and say that it was broken internally, but it did not show symptoms physically, and it never crossed our mind to pull the rotor because it was brand new.

I had an old rotor off of the old vacuum advance dist, I took a picture to compare.

I tried to contact the company rep that helped me earlier to let them know what the issue was. I just thought I would share this with everyone because it was presenting very strange symptoms.

So I decided I at least needed a temp exhaust on the car so it was a hair bit quieter. I went out and bought a flowmaster 40 series muffler. It is a little quieter haha I will have a video up soon

The issue was resolved with the distributor very easily. I will never complain about Ireland Engineering's customer service!

-no it does not have fully working brakes yet
-i think it has just a little poer ; )
-It is going on the Dyno again soon because of the prior issue.
-I got a grade for the engine and I get another grade this year and next year haha

anyways . . . yes it is a one wheel wonder haha : P
(BTW my roommate was filming and joking around haha )

So I took a shot at starting the wiring, it was going well, then realized that I was missing the headlight section. So I hope I get one haha : P I contacted the company.

I took a look at the brakes once again, and I found after taking the driver rear caliper APART, that there was sand cast in the bleeder, sealing it shut! The brakes do feel a lot better, but still not supper hard.

Background/Test:
Running the car on the Dyno was a class project, to be specific a senior project. The whole car has been getting me grades since last year when I rebuilt the engine in class.

When I did the original research on the water methanol inject I was a little skeptical, and that was the nice way of putting it. I heard that there could be high gains from adding this kit to a turbocharged vehicle, but I could not find much information on dyno results for any naturally aspirated engines. Anyway I decided to take the risk and purchase a N/A Water Methanol kit for carbureted engines from Snow Performance.

When I got the kit in the mail, it was awesome and packaged beautifully. The installation directions were some of the best that I have scene and made it very simple to install. Basically the system runs when the vacuum switch senses no vacuum, in other words, WOT.

I built the engine for midrange power and that is exactly what I expected out of it, and I got it.

The first dyno run was not shown, because it only went to 100mph. I chose the second one even tho the graph is not as pretty, just imagine a nice pretty line haha. The run shown on the graph went very well, for some reason I did have a small issue with the graph. The engine was bogged down at 40mph in fourth gear and pulled up on through, but it was not very satisfying.

The run the 50% water/meth injection went smoother than ever. At 40mph the engine did NOT bog down, it just went. It easily without a care ran stronger and smoother than the previous run. It actually ran approximately three seconds quicker up to 110mph. The HP/TQ gain was exactly what I predicted, and it was not much. It is something that you can feel and hear, and it sounds awesome. I have not had a chance to run the car on the street yet because it is nowhere close to being legal.

With Water Meth:
115hp and 115tq at the wheels

So I am trying to get ready for AutoX this upcoming weekend. We riveted in a floor pan in for the time being, it will be replaced at a later date. Also I did pick up some gauges. : )
