Griffith - LT77 question
Discussion
I had this thought on my last car. TVR Power didnt recommend lots of power with the existing LT gearbox.
Engineer1949 who supercharged the 4lt Chimaera runs the LT77 box with no problems but he had this rebuilt before increasing the power. There is also the 380 version of the gearbox, not sure what it is from but it is meant to be stronger.
Not sure what oil you use? If you dont already use it, I would try Difflock. Made a huge improvement on the smoothness and syncro noise of mine on track days.

Running 287bhp through my LT77, have a watch :-) = http://s1354.photobucket.com/user/gmw9666/media/IM...
That vid isn't working.
I'm not far off 287 already - and the gearbox was off for a refurb recently.
The question is what to aim for without needing gearbox work.
At the wheels options are 300-320, 350-370 or 400+ depending on the set up.
The head part of me is leaning to the middle option - SC with intercooler.
The heart part of me says bigger it big blower, new injectors, AFM etc and go for the big power.

These guys seem to specialise in LT77 gearbox rebuilds

To a large extent it's this
I ran an LT77 behind a tuned 5 litre in my V8S, never had any problems at all.
That's because you've got a modicum of mechanical sympathy.I ran an LT77 behind a tuned 5 litre in my V8S, never had any problems at all.
TBH, I've expected mine to give me more trouble having done 80+ standing starts in the past few years, but touch wood its been ok after changing the nylon selector bushes & several oil changes. The weak point I've found seems to be the CV joints.
