Hey everyone, I just ordered my procharger d1sc and I've been reading a lot on the dual key vs single key. I am looking for experienced answers this is on a street driven car and will see maybe 700hp to the rear(hoping anyway). Any input on just leaving the single? I have a dual key crank and had a similar setup on my 6-71 but sold the complete setup. I'm wondering since I just bought a single key balancer if I should upgrade or will the single handle it or shear. I've read that a single can handle up to 1000 not sure if its true or if I should just order a dual key one?
