Hi guys After a 2y search for a Mondial I found the right one for me. It's an early QV 02/1983 registration. Have the car now since 2w. Doing research on the car I found on the swiss "Typenscheine" CH 0251 28 =(certification of the car for Switzerland) that from 9.12.1982 it changed to "S" (=Switzerland/Sweden) in the VIN: Image Unavailable, Please Login The certification from B (=EU) is from 25.02.1982. Changes from VIN B to VIN S are: kW: -4 dB/A: -3 The B VIN uses 118353 as exhaust silencer and S 120703. That is the only thing I can spot out of the certification document. I compared the both silencers from online pictures and they look the same. So I concluded that inner construction must be different so it be quieter and costs of power (the car is very quiet!). I spend some time researching the internet and FC and found some information, but only 3.2 related, e.g.: So my questions are: Does the S-QV also have different gearing? Are there other changes on QVs from EU to CH? Where can I find some original sources with that information? PS: My car does not have either cat or airpump for the exhaust. Many thanks! Elvis
You can go true the technical pages of eurospares = mondial QV There you find differences between the types. Like = https://www.eurospares.co.uk/Ferrari/Mondial/Mondial_3.0_QV_(1984)/PartDiagrams/023/Main_Shaft_Gears Differerent main shaft and gears.
Normal for a Swiss 308QV/MondialQV. I believe a cat and pulse style air injection wasn't introduced until the 1986-87 timeframe on CH 328/Mondial 3.2. Only 1983 US 308QV/MondialQV got the belt-driven airpump -- all other 308QV/MondialQV that had air injection have the pulse air injection system.
Forgot to include that there is some gear ratio information for base (euro), US, and CH (Swiss) 308QV shown in the tables on page E7 of the 308QV/328 WSM -- you can get a copy with this link: https://www.dropbox.com/s/izplbjlkn5xdp1s/308QV_328_workshop.pdf?dl=0 Not 100% that sure it would apply to base (euro), US, and CH MondialQV, but I would guess that it might.
Hi all Thanks for pointing me in the right direction. I used the 308 WSM and online parts catalog to figure out how it probably is. The 308 uses the same parts then the Mondial, so I reckon 308 CH has the same gearing as Mondial CH. Gut feeling was that Mondial should have shorting gearing cause of weight, on the other hand, it's more a "GT" then "Sports". So the Mondial QV Swiss has longer 2, 3 and 4 and shorter 1 and 5 then Mondial EU. I did some calculations, didn't come with the exactly same numbers then the 308 WSM, but close enough.

One thing that can muck this up is sometimes the numbers they give in various "gear ratio" specs are: gearbox + diff transfer gears + gearbox + diff or they just make a mistake The euro Mondial QV OM has a good table of the "gear ratios" in Section 1 -- that would maybe be a better reference than the 308 WSM or at least another reference to compare. (Give a shout if you don't have access to a copy.)
I forgot to attach the excel. Feel free to play with it I did calculate with transfer gear (0.9), that matches so far, but after adding the diff to get the final ratio it doesn't anymore. What I like is that the CH version has the higher jump from 1st->2nd but the rest of the gears have a closer ratio then the EU. That confirms my gut feeling driving the car. Not sure what Ferrari was thinking of, maybe because of the hills. The Sweden version would also have "S" in the VIN, but the EU gearing, didn't realize that till now. @Steve Magnusson: I did check my QV OM, but says nothing about gearing. I find it also quite weird, that the manual is in Italian/French/English while the car was sold new in Zürich (German speaking part of Switzerland). Where can I find the EU OM? Thanks!
Are you saying that you have a specific OM for CH version Mondial QV, or is it more of an CH version OM Addendum that has just a few pages? Any chance you can scan and create a pdf? This link should get you a copy of the 241/82 OM for a euro Mondial QV: https://www.dropbox.com/s/3ne0nkw3snudfp9/MUM_MondialQuattroValvole 241_82.pdf?dl=0 See page 13 (of the OM) and the page it references.
I have "a" manual that was with my CH QV. Just checked it compared to the scanned one: Diff ratios are the same (U.S. one), so probably there's only one manual which has the U.S. rations only (page 13)?
