Lsd or not

[bohemath777]

I have found a LSD centre 3.3.1 gearing...
Wondering on opinions if it would be a suitable combo to go with my T5 and 5.0 Tickford 220kw motor...I thought with the T5 having such a tall 1st gear thought it might well together...Any thoughts guys

I took LSD a few times. So I would say no.

Mr 777,

IMO the ratio is more important.

My RMC/GForce with stroked 351w (350hp) 5 speed T3550 with an open 3.54

Jad diff was excellent. I replaced wit with the same ratio LSD and its fab but it

is a handfull in the wet. The 220kw motor will still spin the single diff but

unless you are increasing the power it will do. The best ration to look for is the

3.54 and see what the price difference is between the LSD or not.

At 220kW/295hp I would say that you are in the 'want' rather than 'need' category as far as the LSD goes.

I know of a some fast RMC / Gforce cobras that have run with open diffs and sticky tyres

I had an open 3.31:1 with my 289 and it was fine, after a while I went to a 347 and spun a lot on the track so went to a LSD centre made up of some later model Jag parts - ended up at 3.58:1 IIRC.

I am very happy with the result but with better tyres I may not have needed the LSD. But then, not all choices about your cobra are entirely rational.

In your shoes I would move the diff centre down the priority chain and progress the rest of the build see how you feel about the ratio once you've taken it round the block a few times.

I generally agree with Stiffy on the ratio being more important however on a day-to-day basis the difference is not stark. You tend to notice it more with energetic driving.
