Started rebuilding the engine for the ChumpCar today. This is a totally stock 944 engine that's a menagerie of parts, but with fresh bearings, rings and seals. Actually, it is getting a Paragon crank scraper, too.

Here's a description of the parts going in:




All we did today is the bottom end - here's a time lapse of our progress:

Nice work Van, wish I could have made it.

Dang Van, I didn't know you gents could move so fast. Is the dog a Corgi? Once more and As usual you make a great video to help us all out.

Cheers,
Larry

dirtyTurbo

Very nice, lots of great stuff I didn't know before

Fara

the poor Corgi didn't get a very restful day.

Also, Most used tool in an engine rebuild: Torque Wrench.
2nd most used tool: Workshop manual.

Love these vids. Great work. They're kind of opposite, in that the one is a completely patient explanation and the second is a torrent of action.

I've been looking through Chump Car rules and I thought that for cars valued over $500 (such as the Porsche) the internals were mandated to be stock. Is this so and if not how is the scraper justified?

Van

Yep - the team mascot.


Valid point. In my opinion, the crank scraper isn't a performance item, but rather an insurance item to give the poor #2 rod bearing a fighting chance to last in an endurance race.

At the end of the day, it's my goal to have a car that maximizes the time on track for my drivers. If we get penalized with ten thousand laps, but the car makes it through the event and everyone has fun, then the mission will be accomplished.

As always great videos !
Looks like superman rebuilding a 944 engine

Is that a 3'rd block you got or did you manage to fix the scoring on the first one ?

Van

It's a third block. From a rennlister.

Cris Brady

So Van, is that the recommended method? Crank girdle on, read workshop manual, remove crank girdle, crank girdle back on

Van

Yeah, you know... measure once, cut twice.

We forgot to put sealant on the back of the girdle, where the oil drains back into the block by the rear main seal. Since the oil pan goes on top of the girdle at this spot, I figured it was worth it to take it off and do it right.

Cris Brady

Yeah, we've all been there. My garage moto is "3rd Time is the Charm!"

Whose part is the scraper in the first video?

Kevin, I got it from Paragon: http://www.paragon-products.com/Cran...nk-scraper.htm

But it's pretty simple... I made a tracing, if you want.
