Powerlab 35R kit will not make 500 HP

dont mustang dyno read lower then the DD?
I wonder if the hi compression stock block is making a big difference compared to a built low compression motor. qqqqball showed his DD at 21psi making only 430whp with crazy tq. I'm hoping I'm wrong but it seems like low whp is due to the turbo (out of efficiency) and lo compression. If so, I too will be pissed once I get it tuned next month on pump gas.

450 on a DD would be roughly 508 on a mustang dyno so that's not the same at all.
you have a gt35r kit on your stock block making 420? how do you know how much more you have left in it if you never pushed it?
once you start breaking 450 dd (500 dj/mustang) a single pump fuel system begins to be a problem. apparently not the case here although it was the case on mine.

I might be on a gt37r but still it's the same plumping, no flow issues here. Initially i had difficulty (PCV valve, boost leaks, MBC, Utec, cam phasing) making power but nothing related to the kit.

It sounds like you are over spinning the turbo to make the boost you want. A friend of mine had a car that was leaking boost everywhere and on 18psi on his sentra the IATs would rise EXTREMELY fast. If you have any leaks or a damaged blade or blockage your turbo would be spinning much faster than it should be just to maintain the boost number you are making which would explain the fast rise in heat. Once he fixed all the leaks(one of them being the compressor cover itself..leaking where it meets the center section) once he fixed everything the turbo was then making a REAL 18psi and the IATs were where they were supposed to be and didnt rise much.

This is what people fail to relize. You can not have both quick spool and crazy top end.
On a side note, these flanges are awesome if you want to swap turbine housings all day:

There is not limit to what turbo you can bolt up to it. Well, I guess the T6 is out of the questions..but who would use that on a VQ anyway.

Quicker spool and top-end power is why this was made
And give it another 2 years and someone will be running a T6.

We built a turbo system for a G35 that put a GT4294R in roughly the same spot that the Powerlab kit has the turbo and we ended up using one of the new Tial stainless steel back housing to make the packaging work without redoing the front end of the car.

get your facts straight 
this is how it went(not actual uncontrolled spike btw)
looks pretty clean at peak...0 smoothing

Seems a little lagy for a "small" turbo, but holds up suprising well up top..
80mph = 4500rpm = 400rwhp
90mph = 5100rpm = 500rwhp
100mph = 5700rpm = 620rwhp
110mph = 6275rpm = 600rwhp
120mph = 6845rpm = 575rwhp
Still a relatively small powerband (trust me, I know lol)......but would have thought it would fall on its face more.....granted doubtfull you'd want to drive with boost controlled that way.

Dude, I was under the same impression when I pulled the trigger and purchased the powerlab ST from intense that I could ez get 550whp to the wheel on pump gas. 1 thing I dont understand is why can't u boost past 13psi on pump gas? If intense is able to run 29psi on race gas why cant u run 20psi under pump and just pull more timing?

do your self a favor and buy the larger hotside before you install, http://www.atpturbo.com/mm5/merchant...egory_Code=GTH it will just barely fit, but you will need to put a heat blanket on it

in any case, this is older news, the numbers ha been replicated anyways, and higher whp and psi has been achived at more than the issues on the thread... I hope op gets things solved soon.

<<<<< = Genius!!!!!!! jk lol
maybe i am confused in what yoaure tryign to say..but FYI the turbos have been and are off-the-shelf garrett turbos. They are not batardized gt35rs turbos like APS. Heck it ships from garrett in garrett's packing

actually you are correct and there is an explanation. From the orginal thread:
remember this was earlier in the proefi testing, it was up to jason.
