Anyone put a converted 9" into their VL's? How much did it cost you? did you loose any power? Do you think it was worth it? Thanx for any replys

Hey, The 9" will eat a little power but are VERY strong diff's. Berlina_Turbo has one in his VLT he is the man to speak to about it. Some original photos have not been recovered yet.

I don't really think you need one in a vlt... The borg warner's in them are very strong... and u'd have to have alot of power to justify fitting one.... That's just my opinion tho... How many rwkw do u have? Whitemajic's right tho, they are VERY strong :P

i did have a single wheeler in my turbo but it got very very noisy so i got a 9' put in with 3.89 gears it cost $1800 fitted. it did lose a little power but it went so much harder bcause of the ratio i didnt notice it its probly a bit of overkill but at least it wont break Some original photos have not been recovered yet.

are the 9" LSD? Are all 9" LSD??? Whats the best LSD to come into on a n/a with the usual mods?!

I dont know exactly how many Rwk I got a the moment somewhere between 150-200 but Im aiming for bout 350rwkw eventually but that wont be for a while, do u think that it is worth strengthining the VL turbo diff or just going for the 9"?

When i got mine done it cost $2500 fully fitted with 3.55's and lsd. So far no problems. The reason i chose to go for the nine inch was that there are stronger parts available if i decide to get a bit silly with the motor. But the diff guy did say that for what i had done to my car at the time the std diff could cope quite well.

vlts are running 9s on std diffs.

A Ford 9 inch diff is not required on a VL Turbo, the standard Borg Warner diff can cope with the power and the 28 spline axels are damned strong, the only reason you would go a 9 inch is the ease of changeing ratio's. VL's generally don't break diffs as they don't produce instant torque like some of the high horsepower V8's. Also a engineer's report is required if a 9 inch has replaced the factory diff. And the TMU Police know what a 9 inch looks like. Me I'd stick with the Borg Warner, I don't like the weight of the 9 inch ever changed a 9 inch centre by yourself, they are very heavy.

the 9 inch comes from back in the day when the whole muscle wars started in america - they built their powerful V8s pretty quick but it kept munchin up the drivelines - every part in their bins was way too weak. So they went to see their truck people and voila - we have the 9 inch and 4 speed TopLoader which now are still extremely tuff pieces of equipment. It's also why they're kinda heavy: they're old and used to be under trucks Some original photos have not been recovered yet.

I would stick to the B/W diff if I was you, 9" diffs are good (31 spline is very strong and ratio choice is insaine 2.5 - 7.0), but you will go slower because of extra weight and less efficiency. unless you are poking out 600+HP don't bother.

I think I'll stay with the turbo diff, Im gonna try a minispool center see how that goes, I think only trying it myself is the only way, some people love 9"s some love the borg warner.

matt (PSI-03L) is running the standard diff but with 3.91:1 gears. the car is putting out well over 350rwkw and it handles the power well.
