On3 performance 78/76
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

I'm curious as well. The price of the 78/76 is so good, I'm thinking about just buying one up because I will eventually move over to turbo. Let us know how that all goes denmah.

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.

Verdad Gallardo the s476r with the 92 turbine is on the way for the truck also
Definately in the same boat. I ordered the Denmah 45 back in the fall and won't be starting my build till this fall. If the results look good for this turbo, I'll definately be picking one up
Quite a few on here have bought one with the purpose of replacing a smaller turbo. I bet we will see numbers in a week or two.
