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.

 

maybe a rag stuck in there?

 

Which is why asked about an obstruction at the intercooler. It's strange that they are experiencing high AIT's with 3" intercooler piping and an intercooler core that large.

 

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.

 

it was like 430rwhp and 545rwtrq,

 

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

 

will this cause more lag and then ill have to also change my flange to the dp?

 

lag vs top end power is always a compromise....

 

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.

i would think the limting factor is how much fuel you pump/flow at lower octane and/or size of injector the ems can handle woudl be the limmiting factor on that..i dont know how is that have anything to do with what boost you run or not being able to make more than 13psi.

i would always focus 1st on the piping of the turbo kit htan worrying about accessories such as the space for a custom tank.... but id say you got room around the FMIC between bumper to do somethign cool and stealthy. Or put it in the trunk

 

T6 flange turbo would be pretty hard.

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.

flange is the same size, but you will have more lag

 

We have attempted to boost to ~18 psi but actually see a decrease in hp at these levels and see AITs going above 170+ degrees. The torque continues to go up at these levels but Hal at Injected feels that the temps are too high. At this point, I don't want the risk the health of the engine to achieve higher torque numbers especially at the cost of topend hp. I spoke with Injected this morning and they are planning on posting they findings including dynos, datalogs and other info soon. They are in the process of packing up and heading to zdayz so it will be a few days until they are able to post this info.

 

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
The 650s who was on the same gt35R using a .82 turbine housing and an E compressor cover, Stage 1 single turbo kit 3'' downpipe, 3'' exhaust, and ProEFI ECU


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.

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.

 

mustang is still an inertia based roller, correct? i'm fairly certain all all dynos that a dynodynamics reads the lowest accross the board.

 

<<<<< = Genius!!!!!!! jk lol
