[s-cars] Boost problem solved, same problem as last time - - - HELP!

[Bruce]

OK, so my mechanic knew where to look for the problem, since it happened
before (although more severely last time). The front cog pulley that drives
the timing belt on the crank is broken yet again. F*ck!

I guess with the track time I'm pulling, it's putting a lot of extra stress
on this area.

So does anyone know where I can get a heavier duty timing belt drive pulley
on the crank? Or has anyone drilled through the gear and crank and inserted
pin(s) to strengthen it? Has anyone else even had this problem??

Thanks all, as usual.
