Just put my truck on the dyno and wasn't happy with my boost I did it on just a inertia dyno with no break and did it in fourth and fifth gear and could not get over 30 psi but on the street I see over 40. I put down 574 rwhp and 1042 ft lbs. The owner of the shop said if I figure out how to spool my turbo on there I would see over 600. I was just wondering if that is true and how could I get it to spool alittle more?

Inertia meaning dynojet? What model? Every dynojet ive been on bigger than a 224 read pretty close to what I was making.

I hit 32 psi out of this s472 and laid down 578 on a dyno jet. Find a load cell dyno they are way better

it has already been said but i drag the shit out of my brakes get it too around 10 psi and you should make more power... FYI the true measurement of horsepower comes in the way of a drag strip :D MPH does not lie

So the weight and trap speed equation is pretty damn accurate? Got a link to a good calculator for it? Cause the one I used said I'm making 660hp lol and we all know that's not true.

Haven't ran down a strip but did a 1/4 mile run with a gps 3 times and averaged 112 mph. Truck weighs 6450.
