Chriscooper1 Posted August 4, 2015 Share Posted August 4, 2015 Hi I'm wanting to put an LSD in my westy, does anyone no what my 3.14 open 7" is worth to sell? Quote Link to comment Share on other sites More sharing options...
Kingster Posted August 4, 2015 Share Posted August 4, 2015 BEC's like to use that ratio, to stop them revving out - so it's definitely on some people's wanted list - not sure of value though? 1 Quote Link to comment Share on other sites More sharing options...
Terry Everall Posted August 5, 2015 Share Posted August 5, 2015 Is it a 7" sierra with 100mm lobro flanges? Quote Link to comment Share on other sites More sharing options...
Chriscooper1 Posted August 5, 2015 Author Share Posted August 5, 2015 As far as I'm aware yes but I'm just going off what someone told me, I'm not to clued up on how to tell really, took the numbers off it but don't understand them. It's deffo 7". The number is 83BG-4033-BA Quote Link to comment Share on other sites More sharing options...
CosKev Posted August 5, 2015 Share Posted August 5, 2015 Why do you want to lower your ratio? I've just gone from 3.62 to 3.38 and it's much nicer for road driving. With the 3.62 my R1 engine hit the limiter in 6th gear at 120mph on rolling road. Cruising at 70mph was 7000rpm in 6th gear. The 3.38 has dropped nearly 1000rpm off the cruising revs, only downside is you need to use first on slow junctions where as with the 3.62 it would go niceky in second gear.

Chriscooper1 Posted August 5, 2015 Author Share Posted August 5, 2015 I'm running a 1700 cross flow, as I've previously said im not very clued up on it all, I'm wanting an LSD but ratios are completely over my head, I do the odd track day... Any suggestions? Cheers. Quote Link to comment Share on other sites More sharing options...
Dodgey Posted August 5, 2015 Share Posted August 5, 2015 Your diff is rare. Very rare. Like said above , BEC guys want them, and also, my V8 runs on one and it means I can use 1st gear. Quote Link to comment Share on other sites More sharing options...
Pistol Pete Posted August 6, 2015 Share Posted August 6, 2015 3.6 or 3.9 on a crossflow will be great and much better than what you currently have. I run a 3.9 with a 4 speed box, 70mph is about 4k revs. 1 Quote Link to comment Share on other sites More sharing options...
cast iron Posted August 6, 2015 Share Posted August 6, 2015 I got an open 3.12 from a breakers yard, lucky find, £80.00. However its no good for my Blade. when i went car engine 4.4 was a superb ratio however that was using a caterham 6 speed. Quote Link to comment Share on other sites More sharing options...
