I have video evidence that the
ford Fiat hybrid axle will stand tarmac starts at 190bhp. Go to Gartrac and they will build you an axle you can trust ether way, I did and it won with constant standing starts, and is going to be used again in Little Toad, see other thread pix.
Atlas is better than both but expensive and getting hard to find, Toads fiat/Ford diff was all steel. A standard English diff will blow behind 140ish Flw, it needs the slipper to work I think its the amount of Torque that's the destroyer

P.S. You didn't just put a whole English under a 131 did you?
