3400 to 3500 stall should be OK...it is dual ball bearing so it will spool very well...also depends on if you have a stage motor because the more cubic inches you have, the less of a stall you need
That's what I'm saying! Everyone wants something for nothing though. I can't believe this thing hasn't sold yet. It has a ported shroud compressor cover as well which is hard to get. This will surely be an awesome turbo on a fully built stroker 3.8 or a stage motor.
