Here's a couple of pics of the e-bay
Trying to get my dyno sheet scanned at work...


The DYNO Sheet is at 16PSI and its called 16.JPG

The Picture is Kinda hard to see, but if you download it and open with a Paint or Picture Program you can see the Numbers a bit better...sorry when i get home i'll try post it again

The Power i made is not maxed out, The Guy who dyno my car said the turbo should be good for 20-25 psi, but my boost control was having some issues and i need an oil change so i didn't want to push it, plus i meet the goal of 350 when i was expecting only 300hp and i can fine tune the e-mange some more but thats more time in dyno, plus I didn't want to push it on 91 Octane...but there was no sign of Knock or leaning out....so there is more power to be made....but I'm Happy!

I made 270 @ 9psi So i think somewhere around that ball park is what your looking at with those mods maybe less, but i could be wrong.

hey i see that your using greddy emanage. How does that work for ya? Im pulling my hair out trying to decide what i want to do about engine management. Im getting 550cc injectors and z32 mafs for my s13 sr20det and i need to know what will be good for up to 350rwhp. Do you have like a jwt tune and your just piggy backing it with that or are you just straight up running the emanage?

It is interesting to see a dyno chart like that. When comparing that chart to a T3/T4, it seems like the T3/T4 is outspooling and making more power than the AX series turbos. This is very surprising because I have only heard good things about the AX-series turbos. What kind of dyno was that?

Since the TQ curve is leveling off at around 5250, I would automatically assume that full boost is being made at that RPM. If this is ture, then it is really disappointing!!

Nice power levels, nice car.

What are you talking about fast spool though? That turbo appears (From the dyno charts) to be spooling slow as could be! A big A/R (.86) GT25/40R will make the same power, spool sooner, and probably costs significantly less (I'm guessing here, but I'd imagine any apex'i branded turbo is going to cost an arm and a leg)

MAN i am having the exact same dilema!! Everything is same for me, including my power goal, except I'm running a T28 on Megan headers, but yea, it would be great if he could answer this question!!!

Someone PLEASE provide input or advice on the usability of this system before I dumo a g on it

I'm curious too... that’s some high hp for that level boost and mods. [/QUOTE said:
Man...This thread is old.... I don't remember exactly what type of dyno it is...they use to have the information on their website..but that is currently down...But Autolink does the dyno tuning for the kazzam kei office S15 and Option Z33 cars when they are in the USA aside from other high HP cars so they know what they are doing.

What would you think is correct HP would be for my boost and mods? Just curious?

The E-manage will be able to run a z32 maf and 550 injectors MAX...in order to run bigger injectors you have to get a full stand alone ECU.... or so I heard from shops I been to and from greddy. I have a stock sr20det ecu with the E-manage piggy back for now. I want to get an EMS or a PowerFC with 740 injectors so I can do 400 hp...Or try for it anyways...
