Turbos and autos
Guys running turbos and autos how big a stall are you running. Reason i ask is because someone posted this on another board about a turbo crown vic running a 3000 stall.
That's not a street-friendly combination. You want to LUG the engine as soon as possible. The turbos are fed from exhaust flow. You may be thinking that the engine needs to spin faster sooner to make the flow, but there's more to it. A 4-stroke engine will flow more volume of air per revolution when under higher crankshaft resistance. The volumetric efficiency rises with load.
A high stall converter will delay when the contribution to flow arrives from the turbos. This narrows the duration of the powerband. Keep in mind that stock modular can't spin over 6,250 and the stock 4R70W can't take over 6,000 rpm safely.
I'll just have some turbo lag. Thats where the 3000 stall converter comes in, it won't cure the lag but it will help. I have one, it's been sitting in a cardboard box for about a year.
