yeah, when you don't have (or the budget doesn't permit) waste gate or 
blowoff valve, you're stuck with whatever the turbo wants to do.

- those things are available and cheap-ish nowadays. Wouldn't take much 
to add a blowoff valve to the delivery pipe from turbo to crossover, or 
to the crossover itself. Dumped unburned air-fuel mix should go outside 
of the engine compartment - or possibly back to the air cleaner, and 
call it enrichment?

The thing that you run into - and maybe some of you have even experimented yourself with this combination - is that when you wind up the engine in low gear, get the turbine wound up to full boost and then make the upshift, it suddenly pulls the engine RPM down with the boost still up where it belongs for a couple of thousand RPM higher. With the low engine speed and the blower still wound up, it gets

Once the malcombustion starts, you can't just shut it off again. Perhaps the availability of a three speed automatic or maybe a four speed would have done it by getting the gear steps tighter. But with Powerglide being a two speed set up we could never find anyway around it.”
