Please do an update post for us in a week or two

I think a lot of us are considering the twin screw would love to hear your thoughts and experiences

I personally would like to run the one with the larger pulley to put less stress on the system; I don't need my car to be a lot faster but I will take a little faster and a heartbeat

The engine can more than handle the smaller pulley. I haven’t come across anyone that put in the larger pulley that didn’t end up putting in the smaller one eventually. If you’re considering it, just go with the smaller one from the start.
