Really a cool run John. Dan Morley from the NWSOC always told me to come down for the Maryhill hill climb show but so far I never made it. I'll probably be there next year though.

Stephan

Stephan,
There's still time!
It seems there was some confusion as to who/when this hillclimb was.
Apparently, the vintage event and car show is THIS COMING weekend!

This event was put on by the Northwest Hillclimb Assoc. (NHA). It was our first time running this hill. We hope it is not our last considering the roll!

I'm tempted to drive back for a day just to meet everyone, but considering how busy a racing month it's been, I really need to spend some time w/ Deb. Maybe Sunday...

Dennis, I was really exited w/ that run! My goal was to break 2:20:00 (140sec) and hitting a 139.013 while beating my primary competition (Bryce in his Scirocco) made me really happy.
The biggest bonus was I DIDN"T BREAK!

Now it's time to put the car on stands, eliminate a few annoying suspension noises, get back to the T5 install, build a roll bar, shed 200 lbs, etc., etc.,...

Reviving my old thread here...

What does anyone know about Centerforce Clutches for the 900T?

I roasted my clutch at the SOC and I'd rather not spend $100 on a new friction disc, so while digging through my stash of parts I came across a used Centerforce. It's a bit worn, but appears very use-able. It actually came from the 83 900T engine that I used for the bottom end of this motor.

Any thoughts?

The Bogus Basin Hillclimb is next weekend and I need to get it back together and put some miles on it before then.

I'm off now to have the flywheel re-surfaced...

John

I recall that those used to be one of the only "performance" clutches that were easy to get for the C900, I think that's what either Dave Kennedy or those jokers from Swedish Dynamics used to sell. Cool idea with the flyweights that clamp harder the faster the engine turns.

What's the worst that would happen?

About 15 years ago I knew two people who bought Centerforce clutches for mildly modified C900 turbos. Both of them had problems with new clutches not holding. Both of them called Centerforce and were told that they wouldn't warranty the clutch because they had modified cars. (which makes one ponder whom they think their customers are). They both put in '89+ flywheels and 9000 clutches and were happy with the result.

But if it's all you've got and there's a hillclimb next weekend I suppose you could try it. Luckily a 99 clutch job doesn't take much time.

I got my flywheel resurfaced yesterday so I'll put it all back together later this morning and give it a try.
It gives me a week to see if I like it.

If it doesn't hold, I'll do the 9000 clutch over the winter.

Thanks!

Well, I finally broke down and sold on of my bikes and bought a set of 15x7 Rota RBs.



I ended up going with the 12mm offset. Looks like they are going to work out OK!

Now to build some adjustable upper trailing links, adjust the Panhard rod, get my slicks put on and take another stab at spring rates and shocks....

Those look great. Nice picture frame too.

RE: Rota 15 x 7 RB's.
Did you calc that the 25 offset won't work ?

I had been running 15x7 -32 ARE wheels w/ 7mm spacers , so that would be ok, if a bit snug on the inside. I think -18 would be just right, and the RB is available in a -20, but they wouldn't fill out Dennis' flares as nicely.
I'll use the AREs for my street tires

John.

Went to the Test-n-Tune at our local drag strip yesterday and am reasonably happy w/ the results.
The goal was to break 100MPH and not break the car.

Now, I have not dragged this (or any other) car for 15 years...

1st run, my brain was still in hillclimb mode and my Reaction Time was 1.6 sec...
I hit 100.30MPH w/ an ET of 15.237.

Second run, I get a better reaction time, but about 100 yards into it, the car loses all power and I had to
be towed back to my pit
The driver of the ATV that towed me was really impressed w/ the factory 99 tow eyelets
As I was at the far end of the pits, I got to hear "well, somebody had to be first..." too many times as I slowly rolled past.
Turned out to just be a bad fuel pump relay, but by the time I diagnosed and jumpered it, another car had blown an engine
and it was going to take some time to clean the track, so I just drove home.
With a bit of practice, I should be able to get it down to the high 13s/low 14s.
But, I got my 100MPH sticker

High 13 low 14 is pretty impressive.

I had a 78 Z28 with a 425 horse small block when I was in High School.
When I could get traction off the line I would see the high 13s.

I finally got around to making the splitter. Takes less than 5 min to attach/remove.
It's 3/8" plywood, secured underneath to the cross member and the rods to the bumper mounts.
The filler between the plywood and the airdam is 2" Styrofoam w/ bedliner sprayed on it.
the spray distorted the foam a bit, but it works. Tookit for a test drive and it does make the front feel a bit more planted. I was planning on testin it at the Auto-X last weekend, but the airport was needed for firefighting and we got scrubbed.

I guess the first real test will be at Bogus next weekend...

Yes, styrofoam does not play well with solvents. As the paint's solvents evaporate it takes the styrofoam with it. Nature wants to take it back.
I see you replaced the grill. I saw Peter Backstroom from the Saab museum buy it right off the car at last year's SOC.
Good luck on the Bogus hill climb this year.

Polyurethane foam is less reactive to solvents, and holds up better to polyester resins.

If you are using polystyrene foam, epoxy resins work well without melting the foam.
