Re: MANX CLASSIC 2023 HILLCLIMB OVER 3 DAYS

Three hillclimbs in three days? That sounds like fun! Best of luck prepping the car! I haven't read through your 20 pages on UK SAABs but I did scroll through and saw some of the pictures. You've sure done a lot of work on it! Did you end up putting that 4-puck clutch in? I had one in an '85 16V Tur...

Re: Per, the 77 99 Rally

Did you ever find a B-engine 900 water pump cover?

Re: rally 99 primary drive ratio

With your new primary ratio you'll probably max out around 145kph. I don't know about Australian roads but I know a lot of 'well prepped' cars here top out around the same speed. But we do get some long straights, we had a stage last year where we had the 900 up to 150kph. Interesting anecdote: we u...

Re: rally 99 primary drive ratio

That's a great setup! So did you build a 31:27 (1.15) or a 31:30 (1.03)? In RallyHo's 900 we run a S&R gearset (pretty similar ratios to FLD), S&R 6:31, and I think a 30:30. We talked a little about what a shorter primary would be like but I think we decided the car was geared OK (on one eve...

Re: Clutch slave failures...WTF?

Yeah, I've had that exact same issue on a 99. The slave popped apart when I stepped on the clutch, I installed a new aftermarket slave cylinder, it popped, I rebuilt it.... I had the same thing with the lightened/re-faced (thin) flywheel and being able to get the cylinder in without having to use th...

Re: rally 99 primary drive ratio

What are you running for the main gear set? 4spd, 5spd, Sport & Rally or similar?

Re: 88 4 door "Rotsaab"

It looks like some of the car got some bodywork/paintwork at one point. Maybe the trunk and roof were repainted? The badging is laid out wrong; (upside down) "S" "900" instead of " 900 S". That usually indicates a body shop that stuck badges back on when they didn't hav...

Re: Rally Suspension project

Shocks: Yeah, take some measurements and see what you think you can fit/retrofit in there. I'd have to dig for #s for valving but whatever we were running or any of us ran at one point may not be ideal if we're messing with spring rates, bump stops, etc. anyway. I started looking at the suspension c...

Re: Rally Suspension project

Springs: There are online spring rate calculators that you can use to get a fairly close calculation for the spring rate. You need to take some measurements (wire diameter, coil diameter, # of coils, shape of the ends of the coils, etc.) and plug that into the calculator. https://www.thespringstore....

Re: Rally Suspension project

Hydraulic Bump Stops: You could replace the old rubber bump stops with the hydraulic bump stops. They're not super expensive at around $200 (though they're expensive compared to cheap chunks of rubber). I think they're expensive when they're built into a full strut assembly, but since we have a sepa...

Re: Rally Suspension project

Inner drivers: I remember you told me that when you did a post-mortem on that inner driver that we broke at NEFR you found out that the driver that broke was 3/8" (10mm) shorter than the driver on the other side. I never found out why there would be different lengths (left vs. right?, 99 vs. 90...

Re: Bespoke Intake Manifold B202

Carbon fiber would be cool but maybe more of a PITA to make yourself than it's worth? I wonder if there are any off-the-shelf plenums (aluminum or carbon fiber) that you could stick on to your runners? https://www.xcessivemanufacturing.com/media/catalog/product/cache/735c8f98bda27246f9ba87c604292ff0...

Re: New to the group.

At least half of the people on here have probably lifted a 99 or a 900 :lol: Crazyswede had a 900 with some front springs that came from a circle track car that we real tall. I think he used stock or some sport springs in the back with spacers above/below the springs. When you got in/out it felt lik...
