And then I stuck some airbags on the PV:


OK, not really, I just had the other corner jacked up.

Got a nice little package from Spec today.

Stage 2+ Saab 9000 clutch. Here it is sitting on the JohnV flywheel:


One side of the disc is Kevlar:


The other side carbon-graphite:


Good for 509 ft lbs of torks, yo!

Probably take it to a MS to get balanced as a pair tomorrow.

Nice. What is the diameter of the disk?

It's the 240mm/9.5" Saab 9000 sized clutch.

Minor hassle in getting the correct sized belts. First attempt lead to belts that are *almost* too long - both the alt and the A/C comrpessor are pretty much adjusted all the way out, and the belts aren't *too* tight. I'll have to replace them with something even shorter before too long.

But the pulley looks great, hasn't flung itself off in a fit of metallurgic revulsion yet. Nice to have shed some pounds off the front of the engine. I think the underdrive part will be of good use when I get the light JohnV flywheel and clutch on and start revving it higher (I've been a bit nervous about spinning that dogish past 7000 rpm, call me paranoid).

are the straps on the pressure plate thicker to deal with the extra power it can take?

I don't know. It's off at the MS being balanced now, can't look at it. I'll assume (until proven otherwise) that Spec knows what they are doing.

Machine shop called - said it needed to have about 4 grams removed to balance it.

Picking it up at lunch. Should be back together and driving again by this evening... if I weren't going to go ride my bike instead. It'll be up and running by the weekend. And I'll start doing some tuning in the higher RPM ranges.

OK, time to put some flywheel on a Volvo!

Put the shiny billet flywheel up to the crank. Put on a couple of bolts. Snug them down. Turn the crank a little. Err, scraping, that's not right. Hmmm...


The last little bit of the rim the ring gear sits on is hitting the block, ever so slightly. Those inward protruding ledges along the oil pan mating surface:


OK, I'm no blushing virgin to making parts fit that don't want to fit. So I grab that trusty standby tool, zip ties. No, those won't work here. *scratch head* Ah-hah! JB Weld on the end of the crank to space it outward some. No... OK, angle grinder to the block, grind off the offending parts.
*brief interlude where sparks fly*




Now it fits without rubbing!


Pressure plate bolted on:


Next up - the whole setup is a bit shorter than the stock pressure plate and flywheel. Test fit shows.... no travel on the clutch fork available:


Here's another picture I took that shows.... pretty much nothing. But why waste some perfectly good pixels?


Oh noes, it's not a perfect fit - time to throw it all in the trash and fire of some flaming emails!!!!!!! OK, not really, good thing I took geometry some 2 decades ago (or more) and understand triangles and levers and the Trilateral Commission (oops, I've said too much). All it needs is a spacer on the other side of the fork. Dig through the spare bolt box, and aside from thinking (for the 54th time) that I really need to sort the metric bolts and nuts from the standard, I find a longer bolt. And some nice tall chunky nuts to act as spacers. Maybe 5/8" worth, more or less?


And voila, like magic - about the right amount of fork travel:


And that's about it for tonight, dinner was ready, and I don't feel like getting grimy again tonight. There's always tomorrow night to put the trans back in.

so is the offset wrong on the flywheel? hows the starter working now since the back of the bendix will be closer to the ring gear?

Starter isn't touching the flywheel currently. I'm assuming it will work properly. If not - some washers between the block and it? I don't think the 'backspacing' on the flywheel is off by more than a tiny amount. The Saab pressure plate is just a little on the short side. And maybe the outward side of the flywheel is a little shorter? But probably mostly the Saab pressure plate.

Still, just a little grinding and some spacers - no big deal. Should work just fine once the trans goes on.

Cool, I was thinking the back side of the starter gear will contact while cranking...and im sure if you space the starter with a full shim and keep it "hubcentric" should be just fine.

Good work.....well ahead of me at this point!

Hope to drive it around this evening. Just need to poke the trans back in. Which is far easier with a T5 - you don't have to maneuver that starter hump on the bell housing around the firewall - you can just slide the trans straight in and attach 4 easier to get to bolts.

(Side benefit - taking off those hard to get to bellhousing bolts is dead simple once the trans is off and out of the way -woot)
