Why would you want such a tall gear ratio? Wouldn't you want taller to allow for better performance?
Did you mean "Wouldn't you want shorter to allow for better performance?"

Awesome project. Interesting to go to irs instead of a stronger live axle, given the various design issues with the irs unit. Did you consider a Toyota r220 diff as well?

No complaints by the authorities that the S600 exhaust norms aren't being met anymore due to changing the ratio.
because the engine was not a stock volvo option, you are allowed to have like 3,5% co from the exhaust by the rdw people.
that is if you don't have to do the expensive tech inspection in lelystad. in that case its treated like a new 2017 (if you get it ready this year ) car and it will require things like anti lock brakes and airbags and such.
does your volvo have U9 on the papers? if so, it might be different but i'm not sure.
Are you factoring tyre diameter into those ratio/speed calculations? If the authorities care about RPM to speed in each gear, then they'd care about that. On the other hand, they can't stop you driving along in any non-damaging gear, so it's weird to care about that.
Gotta think the big Benz ran a taller tire than the Volvo will - which would have the effect of shortening the 2.65's. Although, with a 25" tire, the .83 top gear and 2.65 rear - 70 mph is hair under 2100 rpm (assuming lock up converter). Just about exactly where I am with 3.55's, 25.3" tire and a .625 5th.

but keep up the good work! would like to see this in person some day
Would love to a detailed write up about the IRS diff swap.
Gotta be nice building a hot rod over there - what with all the "help" you're getting!
Can't wait to see your mounting solution for the diff.
I should have the adapters finished in a week or 2 maybe. If they fit as expected I'll do a group buy for them if there is enough interest. I'll make a set that fits the 960II too if there is enough interest.
I'm interested if you'll provide a Teilgutachten for the 740 chassis!!!!
nice work! any way to flip the intake manifolds around to avoid cutting the throttle bodies out?
that would be too easy
No that won't work, it's 1 big intake manifold and it slopes down at the front a bit for hood clearance.
