Hey guys,

Last year we finally got our 924 motor together only to have a crank bearing failure on the blocks. After looking farther into it, replacement parts were just too hard to find or too ex ...

Great info guys, thanks.

Where do you guys like to get your stock clutches and flywheels from? Pelican (our normal supplier) seems to be out of stock.

Understood, thanks!

We were thinking of using the South Bend Clutch Stage 2 Endurance kit.

Any thoughts on a flywheel? Ours is missing teeth.....

Where do you guys get your clutch parts from?

Any recommendations on what we should use?

OK, perfect. Thanks!

Gone for a couple of days, I'll get the get the diagram for the MSD when I get back.

Awesome, thanks! I've been using the MSD diagram, but I wasn't sure what type of distributor I'm using.

He ...

Correct; one is signal from the Hall effect sensor, the other is the shielded ground for the co-ax wire.

Interesting. I think I missed that ground. I will fix that!

I think I've figured out the Alternator and Starter now.

Now I'm moving onto ignition.

Does anybody run an MSD 6AL with their 924?

How do you connect it to your distributor?

It seems t ...

OK, I'm rewiring the car from scratch.

I have a few questions:

I've been going over the wiring diagrams from the Haynes manual, but I'm struggling.

Alternator:

Where do these 2 wires go? ...

Oh yeah, we know. It's pretty clearly laid out in the various series we plan to race the car in.

Generally, they require 0 to 5 degrees. That we easily accomplish.

Oil pressure: no, that's not at idle. At idle it'll be below 1 bar hot. Those are on-track numbers.

Copy that.

I'll be out this weekend, I'll get an infrared temp of the tranny(not oil) for you. ...

OK, Here is what I got:

RPM: 6k max (lower if needed)
Water Temp: 210F max (normal 190)
Oil Temp: 270F max (normal 220-240)
Oil Pressure: above 2-3 Bar at idle
AFR: 13.0 or 12.7

Still need ...

Fantastic info guys, thanks!

OK, I'm now setting up our analog gauges and telemetry systems.

Some further questions:

1. Keeping in mind this is an endurance car (12 and 24hr races), what ...

I safety-wired my CV bolts for a few years. It got to be such a pain, then Stage 8 came out with their bolts - so much less work. Safety wire is cheaper, but a lot more work every time you touch a CV. ...

Thanks for your very thorough list!

Starter-I've cooked two of them because the bendix/solenoid is right next to the MSDS headers. Put in a heat shield. Vaughan suggests a little sheet metal.
