Re: rally 99 primary drive ratio

Hi Geoff, I made a 31:30 (1.03). I think with the 4sp it will run out of legs on the longer events. It used to max at 180kph. Haven't driven it in competition yet as there have been no events due to rain and flooding since last November here. Yeah, launching even in first was a big time loss with lo...

Re: rally 99 primary drive ratio

Sorry Dennis no photo, I don’t realise until the job is finished that there are others that would be interested in seeing what’s been done. I’m going to make a 30/30 for a friend in Sweden so will take pics of that one. Geoff, the gear kit is an FLD straight cut 4sp dog change and 6:31 ring and pini...

Re: rally 99 primary drive ratio

I'm interested to see how it goes with a standard gearbox, should have great acceleration. I think it will be way too short if you are running a turbo.

Re: rally 99 primary drive ratio

The process is taking a top 31 tooth cog and machining the centre out and a lower 27 tooth and machining the teeth off. press the 27 inner into the 31 outer, tig them together and you now have a 31 tooth lower gear. Fit a standard 30 top gear and then add one link to each chain. You can cut down eng...

rally 99 primary drive ratio

Hi, been a while since visiting (too long actually). Finally fitted the primary ratio I made for the 99 rally car and WOW, what a difference! Thought i had a 31:30 fitted but found it was a 31:26. I made ( with Dennis's help) a 30:31 and changed the ratio from .84 to 1.15. The car is a different ani...

Re: Been a while.

With the camshaft fitted it’s all over at 6500. Using B234 turbo injectors in the original place in the manifold, welded in some bosses. Changed over to LE type injection. It won’t let me attach pics, maybe too big a file. Not very tech savvy but will try some more.

Been a while.

Hi, It’s been a while since I have posted an update on my 99. I had to rebuild the engine and decided to go forged. Used Toyota rods and cut the bearing tags to suit the Saab bearings. Custom pistons and pins which resulted in a 1.2 kg weight saving over the original piston and rod combination. Was ...

Re: Wanted

Hi Dennis, The fires are very bad but mainly in New South Wales, Victoria and South Australia so we are safe for the time being. The gear count is 30:27. I need to make a modified set for the rally car. Flares are still going strong except for the front bottom quarter of the rears that just keep get...

Re: shifter

I have modified the front 4sp case to utilise the later 5sp spring loaded detent. Keeps the lever in 3rd/4th plane. Don't have any lock out for reverse as I don't think it is an issue, it's not a natural movement to select it.
