Is there much difference between the blob 5 speed and hawk 5 speed?

Obviously I can't say how long anyone elses will last.
35 hard launches even with your fancy footwork, thats under 9 miles of reckless driving.:lol1: I won't mention what your clutch made of things YouTube - pro street drag series now where is second gear :lol: Roll on next season.......

Seriously tho, I was shocked how long it lasted. I bet that the box had a few (hundred) dyno runs and spirited road driving too.:wonder:

IF FITTED FROM NEW.

There is no oil made that can make a gearbox last longer if it already on its way.:cry:

It will make things feel better and maybe hide synchro crunches for a while.

BUT think about it - of someone made an oil as good as that, within a week he'd be able to buy Microsoft.:luxhello:

Subaru gearboxes already have magnetic drain plugs fitted.

LOL - the operative words were "it was fine" - it was all working nicely when it came off for the 6 speed and I have never done a drag start in my life so all rolling on stuff on the road/track rather than 7000rpm and a swift sidestep... :D

:luxhello:

I'm within those ranges! (Well, 0.8lb ft 'under' on the torque and 4.3bhp 'over' on the power LOL! :D)

Should be 'fine' then :).................................. *immediately breaks 'box* :mad:
