Ive just seen some of the cossy power ed 7 videos on here,
but, what would the difference be in a 300bhp cossie and a 300bhp busa turbo???

about five grand!

maybe a bit less but yeah lots of money and about 100kg or so, but your getting to the seriously uncontrollable on the road stage with either.

can you buy a turbo,ed busa engine for 5k? perhaps from the same place that sells freelander diffs with atb for 600 quid

he asked about the difference so a cossie motor is more like £1250-1500 for an half decent one so a £5k difference would be £6.5k , my comment was a busa turbo at that level of power can be done and done properly for less than that (but not much less).

in the last month there have been 4 freeo dffs with quiafe internals and the most one went for was £550, the cheapest was £102 but that was because the seller rather stupidly forgot to mention quaife in the listing.

point taken but a new diff and atb would be over a grand though wouldnt it? so 600 isnt that bad in comparison for a brand new 7"

a brand new non lsd is about £400 ish and a new atb is £550 and westfield charge a rediculous £1270 for a complete unit. i was luck in that mine is brand new with original receipt for registration time for £500.

a new 7" for 600 isnt that bad in that atleast your getting something reliable but i thought the classic conversion ones werent new (they use reconditioned parts rather than new) in which case its on the expensive side.

either way if i had the cash i would have gone for the muffet one but £2k is alot for a diff even if it includes reverse and has quick change ratios.

I have just been looking on the Muffet website and it says that the unit is 23.2 Kg, including CV joints.

Does anybody know how this compares to:

A) The weight of a Sierra Diff + 2 lobro joints?

B) The weight of a Sierra diff + 2 lobro joints + a Quaife reverse box?

I am sure the Muffet unit must be lighter than B) but if it were lighter than A) then that would be very impressive. If I could gain reverse, gain the ability to swap ratios at will AND shed wieght then £2K starts to become quite atractive.

Especilly since my Quaife ATB Diff has ended costing over almost a grand. £475 + Vat for the ATB unit from Rally Design = £560. £90 for a 3.38 open Sierra Diff, £50 for a boggo LSD Siera Diff to swipe the drive flange inserts from, £50 to have the inserts machined to fit the Quaiffe and £200 to have the unit built with all new bearings and seals by Road & Race Transmissions = £950!

In fact, if comparing like for like with the Muffet, I should add to that the cost of 2 CV joints and 2 CV boots which must come to about £80, so indeed, comfortably over a grand. Surprisingly then, I bet if I were to go out and buy a Quaiffe reverse box and pay to have my propshaft modified it would probably have cost me more than if I had bought a Muffet, Doh!

the sierra diff inc lobros is just over 24kg so the muffet is seriously light in comparison. an sierra diff plus quaife box is about 32kg.
a nova racing reverse box (about 2/3s of the weight of the quaife) might make using a freelander diff lighter still but i dont think its worth it for the hassle if you are paying full price for everything so not getting a cost saving either

classic do new 3.15 , 3.38 gear sets the 3.15 is a lot meatier than the ford 3.14 as we compared the two last time i was up there. im sure the freel diff is fine for bec and smaller motors but i wouldnt run my v8 through one they just look a bit diddy to me .
