Dyno @ 15lbs of Boost

[Turbo28]

I was doing some work at a buddy's performance shop and decided to
put the car on the dyno. I only took the boost up 15lbs (only had pump gas in it) It was a Mustang Dyno and the car pulled 350Hp and 400Tq +/-
My air fuel was little lean on the first pull at about 12 , we riched it up on the second pull to 11.5 but it did not make much difference on the numbers.
I was wondering if these numbers were about right for my combination and 15lbs of boost on a Mustang Dyno?

Looks about right. My dyno numbers came from a Mustang also. I ran 26psi and 24 degrees. We ran it up to 5900 rpm. Stock MAFS and p-trim turbo killing my combo. When i put on he FAST and the 70GTQ i should be good for 620-630 at the same boost. A/F ratio was 11.3-1

Sounds right to me... with Alky and more boost you would probobly see 100+ hp gain... 15lbs is low I bet you could have pulled 16/17lbs. You spent all that time and cash on nice parts, now spend a bit more and throw alky on it so you can use all of your performance part's to their max potential! Should be a street monster either way though!

Given that its a mustang dyno, its reading about 40hp lower than you would see on a dynojet. Also factor in the AC converter, which slips alot and is probably hurting the numbers alot more. High stall TC's tend to make the numbers come out really crappy. Ive seen a 600hp mustang make like 360 at the wheels with a 4500 stall TC in it. Only way to really measure your real hp is to weigh it and get some 1/4 mile runs in.
Given those disadvantages, you've got a really strong motor there. Take it up to 23psi, run 25 degrees timing and spray some alky, and those numbers would be ridiculous.
