Default Power Guess

I was thinking about throwing my truck up on the dyno,but first i thought maybe someone here could give me a close estimate to RWHP?

*4in downpipe to 5in
*#100 plate all the way forward and afc housing
*injen cold air intake
*40hp sticks
*pushing about 33-35 psi boost
*aFe intake manifold
*pump is pretty much maxed out

Any numbers would be greatly appreciated,just thought i would ask on here first

for 300 to 350 you will need more timing, gov springs, mod your wastegate and a trans that will hold it.

On a side note your pump is no where near maxed out

What timing?16*?4,000 GSK or 3,000?And what do you mean mod my wastegate?I dont want to put anymore than 35psi on my stock turbo?I have a bighead wastegate and a boost elbow?
Would i be closer to 300 if i threw 70-90HP sticks instead of 40?

just because they (pro-noun people) are claiming 40 hp injectors, does not mean 40hp

and you asked a loaded question.

I would put it on a dyno and then come back with numbers and then we could sit down and really help you.

with what you have posted, I have seen numbers as low as 250 and as high as 350.
all depends on if it is set up right.

Alright,Thank You,and i understand that it doesn't mean "40hp" and these injectors are only 4 hole and didn't see much performance only 1-2 MPG increase,so i was thinking maybe a 70-90 would maybe wake her up a lil

Why don't you want to push more than 35psi with the stock turbo? I realize it isn't particularly efficient up there, but I regularly bury the needle on my 40psi gauge with my stocker with no issues?
