911 Carrera RallyCross Project

Im torn on which mazda to bring...

In reply to fidelity101:

If you bring the 2 you have to drive backwards...

How good are Porsche 911s?

Well, Scott Harvey just won the National Challenge RallyCross event in Modified class in ours despite us normally running in Prepared in a car that, from a performance perspective is essentially Stock!

So, pretty much amazing.

Some actions shots from the recent RallyCross have emerged:

Currently working on the Rothmans/BRAID/TIM graphics package. Stay tuned.

This is great, it looks like the barns in the background are off a cliff edge, almost looks Pikes Peak-ish

I know it has been prepped to PR rules since it is a 'P' car after all, but it will be welcomed with open arms in the Mazda, err, modified rear class. Edit: I just went back and re-read the first page in case blackmail is required.

Thanks for the invite but I have a dinner planned with friends.

We have finally started work on the graphics package for the car. As you may have read earlier in this thread the goal is to do a TIM/BRAID version of the classic Rothmans SC/RS graphics from the 80s. We are trying to stay true to the design while substituting our BRAID blue, TIM yellow and red and adding a gray TIM into the stripes. The current bumper arrangement is quite dissimilar to the SC?RS so we may have to fudge that a little until we can replace the bumpers once we move up a few classes.

So far:

We layed out the design with flexible pin striping tape.

But started on the engine cover as it seemed easy and defines the stripe's end points.

As we will be using magnetic numbers on vinyl number panels we thought we'd remove one layer of vinyl to aid adhesion. You can see the sanded down clear coat under the white.

Cutting is hard.

Actually the whole process proved more difficult than anticipated so we brought in some professional advisors from One Soul Graphics.

Adam uses cutting edge technology (knife, get it?) to cut the vinyl.

But we did this side ourselves :)

Looking good!

jealous = me. I have to do all my crap with rattle-can and tape, since I'm too cheap for a wrap :)

Bad ass. Will it be out this weekend on Woodward?

Was there last night but racing Saturday. Might pass through this evening after soccer, around 9-9:30. Maybe Thursday. Friday it will be on the trailer.

More progress this week:

Then we had to stop and load it onto the trailer for the RallyCross tomorrow. That is what it's for after all. Just a few more details to finish off next week.

Are you going to nationals this fall? I've been undecided, but being able to drool over this car might put me over the edge.

See you at Crystal tomorrow.

Nope. My 50th birthday so meeting good friends in Pittsburg to celebrate "properly".

The wrap looked good today. How did you end up doing?

Set out to get the new shiny vinyl dirty at the Detroit RallyCross.

No mud but plenty of dust which is appropriate as we dusted the opposition, again.

We tried a GoPro for the first time at this event. Unfortunately we had lost the instructions so got plenty of video of Scott turning it off DOH! here's one iPhone launch Video we got as a backup.

Uh oh! found this on the trailer this morning. Doesn't smell like transmission fluid so must be oil. Doesn't really smell at all to be honest. Coming from the bell housing. Main seal? Is it called rear or front main seal on these?

I guess the engine is coming out this week :(. Anyone want to help? What are the likely culprits? What "while you're in there's" should we do?

Brace yourselves for lots of pictures and even more questions.

Managed a little progress yesterday then someone came over to buy our Outback Rally Wagon so job stopped. It was late anyway.

Here's more pictures of the leak:

Drained the oil

Disconnected all this stuff: electrical connectors, fuel lines, vacuum line.

Disconnected the HT lead and found a cracked wire

Disconnected the oil lines except this one which would come apart. Any suggestions?

O2 sensor. Why is the stud not connected?

Was working on the main wiring connector but I may have broken it. Then the phone rang.

More engine removal progress.

Trying to remove stuff that's already removed. Where is this supposed to go?

Part of my problem working on this car is lack of familiarity, especially with electrical connectors. Case in point:

Apparently some people have struggled getting this through the bulkhead. I didn't have a problem though.

FAIL! :(

Not FAIL :)

Oops

OUT!

sad to hear that you had to pull the engine. Awesome car though

Sooo, I was watching this project intently, and finally picked up my own 911(SC) early this year. After having it for a couple months and even bombing down a few dirt/gravel roads, I can't imagine punishing it around a rallyx course. You guys are insane!

Why?

Their rallycross courses are rather smooth and non-punishing.

Cleaned the engine and transmission some yesterday then started looking it over.

Missing screws:

Should this have a cover on it?

Transmission off

Yuk! lost of dust from rallycrosses.

Is this the stock clutch then?

Is this leak coming from the pressure sensor or the oil line?

More dirt

Not much clutch disc left

So, not sure where the leak is but leaning towards the crank seal.What do you think?

What's this on top of the transmission and why is it damp?

Today we start ordering parts.

:)

1. yes, looks like crank seal to me.

2. the thing on top of the transmission is probably a purge/breather I'd guess. In case the tranny is getting too hot/foamy it allows the fluid to expand out. I don't know Porsches but I've seen other cars with similar (and on diffs as well).
