The Finns haven't had much driveline trouble, even with 500 lb-ft... the tranny needs beefing up with the SL600 clutch packs, etc, but otherwise it's amazing how much power it all can take. The one guy with a 500hp 606 stuffed into a W124 running high 11's had slicks or drag radials, btw. There are larger diffs that are bolt-ins if needed (from the 400E/500E).

As for the amazing cars in Finland... I remember reading about manditory tranny rebuilds every 10K mi on one of the sites... that pretty much negates any benefit as far as i'm concerned... maybe I'm wrong about that though.. Also, what are you gonna do with all that power with stock gearing ???? Is there any way to put a 5-speed behind a 617? 5 speed with long legs in the rear end might make that extra juice useable (read: fast cross-country trips). |

There's an ideal way to control it, it's an amazing device, you've even used it before, it can save tires, save trannys, even save fuel, it's called a THROTTLE! Pull your foot out of it!

I wouldn't think 10k rebuilds are common or necessary, but it could be possible on some of the more extreme or abused cars. RENNtech built 6.0L gassers with over 400hp and 400lb-ft based on the same tranny, and I've never heard of them needing frequent rebuilds. Maybe the stock tranny blows up after 10k, lol, at which point it's rebuilt to withstand the extra power.
The Finns don't do manual trannys because the MB clutches and/or gearboxes can't handle the torque. It might work on a low-output setup though. Most of the Finns are using, I believe, stock 2.65 gearing... most 123's have 3.07 gears which is kinda low. |
