I wonder how this turbo would compare against the standard S475 on a 5.3l. I ditched the on3 76 because of the ridicule amount of backpressure. on 15psi after 6200rpm my powerband would fall badddddd.
of course this would come out after I already made the new pipes for the s475. Ohh well.

i have a built 370 truck, with a on3 76/64 on it, ( it was a stock 4.8 truck)
and my friend just bought this 78/75, so i am going to directly swap it and see the hp difference
it has SERIOUS trouble getting over 500whp and is capped off at near 550, so it will be interesting to see how much more i can get out of the 78/75

With that forged 370 we should really see how much this new on3 78mm will put out.
I thought for some reason you posted somewhere that you guys were gonna order a billet s476 for the truck. I like this plan better ha.
