I didnt know they where available?
I thought they where only for h165 and h190.
To tell you the truth I dont think 3.7 is enough for a hot a14 or a15
in a lightweight 1k, at 100kph it will still be revving around 3500rpm
but I havent worked that out just guessing since an a10 with 4.11 makes
about 3900rpm at 100kph with a 3.9 around 3700rpm? and 3.7 maybe 3500?
at 1:1 can anyone work this out with standard or just larger 1000 diameter tires?
The H150 differential in 3.7 to 1 [HB37] was standard in Aussie PWB310 vehicles [Sunny Sportswagon with factory A15]
There was a 3.54 to 1 ratio in some B310 models sold in overseas markets.
The standard diameter for a stock 5.50x12 tyre used on B10 cars was 552mm in diameter but I can not possibly think of any reason why anybody would use a tyre of that diameter on the rear of any 'performance improved' B10 model.
I used 205x60x13 tyres on my B10 sedan & after some modest mods to provide clearance, they proved quite staisfactory.
These were 575mm in diameter & provided a modest but usefull boost increase in overall ratio. So did the 3.9 to 1 diff from a 1200.
I plan to run my 3.7 diff with my A13 & 5 speed. This will be a bit of a balancing act as the first gear ratio is the same as second gear in a regular 4 speed so the diff ratio needs to be low enough to allow a half decent take off, but high enough so that the engine isn't screaming at normal highway speeds.
