- Start the engine, run for 2-3 minutes idling watching oil pressure and temps.

- Stop engine, check for leaks, check fluid levels.

- On Dyno, do repetitive 4th gear pulls from 2-5k RPM under load. (I used the car's brakes to add extra load)

- Stop engine, check for leaks, check fluid levels.

- Do 4th gear pulls from 2000 RPM to redline on dyno.

I had probably 1.5hrs of runtime on the engine after the above. I then drained all the oil and coolant from the engine, and cleaned the oil filter. (I'm using an inline Peterson oil filter) I've also re-torqued the head studs, and did a general check of all the electrical and fluid connections on the engine.

Engine has currently been filled back up with Royal Purple Break-In oil. (10W30) I'll probably run this for a couple more dyno sessions then change to "normal" oil for this engine.

I can't stress how important it is to generate lots of cylinder pressure to help seal the piston rings. The window of oportunity for this is very narrow after machining, you probably have 2hrs of run time to get 80% of the break-in done. Again, I'm not talking RPM, but cylinder pressure. On most engines, peak cylinder pressure occurs at peak torque...luckily for us that's at a fairly low RPM. (3500 RPM)

Porsche loads all of their cars really heavily on a dyno at the factory before they go to the dealers...

How about engine braking, is that a good way to break in a motor?

It can be part of a break-in routine, but I don't believe its an effective measure by itself. Engine braking creates vacuum which does help press the rings against the cylinder bores, but it also places a huge load on the rod end caps. The force applied to the rings under engine braking is not as great as accelerating under load.

My choice was to acclerate hard under load, and use engine braking.

Update for yesterday and today is more of a "what's been done" list:

- Drained oil and coolant from engine.
- Disconnected fuel lines
- Removed in-line oil filter; cleaned and inspected filter element.
- Removed VANOS, camshafts, and cam trays.
- Re-torqued down head studs.
- Re-installed cam trays, camshafts, and VANOS assembly.
- Drained all "dyno fuel" from fuel cell. (Put it in my truck)
- Put fresh 91 octane gas in fuel cell.
- Suspended engine with hoist.
- Removed solid engine/tranny mounts.
- Cut top of transmission tunnel out. (Needed more clearance for some things)
- Installed Urethane engine/tranny mounts.
- Re-installed fuel, oil, and cooling system. (All hoses and radiator was out)
- Filled cooling system with 7.5L of coolant!
- Filled engine with 8L of Royal Purple Break-In oil. (10w30 mineral oil)
- Tried to start engine...realized I need a ground strap now.
- Started troubleshooting idle issue on engine.
- Got power windows and locks working again. (I was having to "hotwire" the windows to move them up and down before)
- Windshield wiper motor functional again.
- Got horn working properly.
- Re-wired fuel pump to work off of relay controled by DME.
- Finally found correct signal for RPM on tach/logger....tach now working properly, LM-1 now logging RPM with AFR.
- Installed Moristech Interceptor piggyback ECU. (Lot of work)
- Did rough configuration of Moristech and test run with engine. I now have full control of fuel and ignition timing.
- Configured 2 step on Moristech...works pretty good.

I'm sure I forgot some stuff...but that's where I am right now. Tomorrow I'm moving the car out into the parking lot to continue configuring the Moristech and getting the LM-1 to talk with the Moristech. Also going to work on setting up logging and display screens with 2 laptops for next dyno session. Looks like I'm going to need a 3rd laptop too...fully optioned AutoEnginuity in the mail.

Cold day on PEI.

I had the car out in the parking lot today with an extension cord run back to the shop to power a space heater inside the car and a laptop. Now that I'm comfortable with the Moristech software...

Dyno session booked for this Saturday.

It will probably be on the rollers for 5-6 hrs to continue with break-in and start fine tuning the combo.

The idle problem I've been sorting through ended up being a wiring mistake I made. Lets just say I've gotten really good at pulling all the spark plugs while testing things...

I also did a compression test today to see how the break-in is progressing. There's still a ways to go before we're in the "sweet spot".

its not quite as well in details as your car, the cars are done with a git'r'done attitude and meeting the Canadian Touring Car regulation and Grand AM and the season is starting soon.

I always hoping for the opportunity to build a personal track car where I can build with no limitations.

Interesting terminology.

At the crank or at the rear wheels?
At the wheels. You can tell both the carnk and the wheels if you want.

That is very still impressive for a 330ci. That sounds fairly close to M3 power vs a stock 330ci !!!

I saw your entry on dragtimes.





That is really good that you had 230rwhp before your build. How many more ponies or whatever do you feel you have now? Did you ever think about stroking the engine ala the Alpina B3S Coupe?

Thank you.

Some days I don't get much of anything done...too much head scratching or cursing going on. It's reassuring to know that some people think I'm doing ok.

I have lots of dyno graphs...it's just that they don't really mean anything at this point. Not to worry though, as always the details will be posted when I'm happy with them.

Thanks for the link, very nice project.

I may be up at Tremblant with my car this year if I can work it into my schedule.

I like to use wheel hp for dynos, but crank hp for track results. The big black dyno never lies...

Loay,

Wow...that's digging into the past. LOL Good memories..

I have a source for a 92mm stroke crank, but it would involve some compromises that I'm not comfortable with on the M54 block. I've chosen to stay with the existing stroke/bore because it produces a fairly good "rod ratio". This will be important when I start laying into the nitrous pretty heavily, as the block at that point is going to be stressed pretty heavily. On steel engine blocks, the "rod ratio" like the 92mm crank has, creates a lot of problems at the bottom of the cylinder bore. It literally deforms the cylinder walls into an oval because of such a high rod angle. I can't imagine what would happen on an aluminum block with 1mm thick steel liners.

The B3S uses an S52 block, which is all steel. (Note only single VANOS in the engine pictured) It's a 3.2L block to start with, so increasing displacement by 0.2L is much easier than adding 0.4L to an aluminum block. It's a very well done engine, (everything Alpina does is well done) but not in the spirit of my build criteria. (Using 330Ci internals)

How much power am I aiming for?

Enough to run an 11.99 in the 1/4 mile with a 2900Lb car.

Update for today:

I recieved the "extended features" version of the AutoEnginuity scanner this morning, and loaded it into my second laptop. I can't even begin to explain how happy I am with this product. Sure it's expensive, but you can see everything that's going on with the engine in real time. I'll give an independant review of this piece at another time, but I'm really happy to be taking this to my next dyno session.

Speaking of Dyno...I have the car on the trailer at the house ready to leave first thing in the AM. Tomorrow night I'll post a dyno graph with some explainations.

There is a lot of stuff going on behind the scenes with the engine that I'd rather not get into until I have a better understanding of things. This is all part of me being new to this stuff, learning, and also it's the first time to my knowledge that someone has built an engine combination like this. It's very exciting, but also very challenging.

My thanks goes out to everyone that has helped with advice, technical support, and product that has brought this beast to life again.

Did you find that the head studs needed to be re-torqued?? And, forget what type of HG you're using BUT what is it?

And, how exactly did you wire the fuel pump relay to work off the DME??

And, the progress sounds good!

I think you should look into an in-car camera and mount if it has not already been purchased or planned on Adam.
