So last friday I FINALLY made the trek to the Bay for a tune. My car thanks me :D Tune was done on the Gruppe-S dyno. Next time will be a road tune, mebbe on some good gas.

The car pulls like a hoarde of Cave Trolls!!! It keeps gaining HP until about 6k, then only drops off slightly before redline. Exactly what I wanted. I just have to be careful coming out of corners, as the front end gets a little light if I give it too much throttle :D

It hit about 260 whp and 270 wtq.

+1 for Ed. He rocks!!

Nice! Looks good. I know the 39 get's bad press sometimes, but I also love that turbo as I even have it on my personal WRX...

From the looks of that graph, looks like a Mustang Dyno, so those numbers are killer! Enjoy it.

it's nice to have full torque below 3500. :)

ed, chime in here and tell us how your road dyno software numbers compares to g-s's heartbreaker!

from what I have seen him post elsewhere, the gruppe-s dyno and his road tuning software have comparable numbers.

nice no.s

That's right... the mustang reads very similarly with my road dyno software.

Thanks
-- Ed

ohh man nice power

that dyno almost reads the same as road dyno software

ifu can drive it good enough u should be good to go with
12.9 - 12.8 times
with trap prolly 104 - 105

How much boost?

That is a very nice set up. Good numbers and a nice pull. Congrats!

Thanks :)

It hit about 19.25 from 3300-4400 RPMs, then gradually drops to about 15 at 6500 RPMs.

Hey downSTI...what did your setup do on pump gas?

How much boost?

19psi peak tapering to 14psi by redline.

My car has the same exact power curve. But, my car is only putting down 250whp on pump (93). Also, I have a Invidia DP matted to a STi CB. My car is very quiet and pulls so damn good.

I like a little rumble on my car :) The cobb has a nice sound, and is not super loud.

I WISH we had 93 at the pumps around here!! Keep in mind this car has a vf-39 on it. What brand dyno did you run on?

So I fould this awesome graph plotter for ecuExplorer data logs (http://www.waygate.net/plotter/). Here are three graphs from my run:

So you are maxing out your injectors if I am reading that plot correctly? I thought the 06's had injectors that could keep up w/ bigger turbos than a VF39.

Looks like he is missing a Walbro. We recommend that anyone with 06-07's doing a turbo upgrade throw in a walbro. We have tuned several 06 wrx's with stock injectors on VF39's, 18G and 20G WITH a walbro and see IDC's of 80%.

It has a Walbro

edit for a question: how does a walbro help reduce the IDCs of the injectors? I will do some reading later, but for now mebbe one of you can answer for me :)

A Walboro simply flows more. An injector is just a nozzle with holes in it and an on/off switch. Up the flow with the new pump, it also ups the pressure, you up the amount of fuel that gets squirted in when the injectors are open. 80% duty cycle is much better. 100% is scary. Engine go boom when it runs lean (if the pump can't flow enough (in volume of fuel per time period) for the engine's needs) ya know. ;)

What does a stock STI dyno on the Gruppe S dyno?

I thought an 06wrx with vf39 was closer to 300whp

What does EQ Tuning get out of a stage 2?

Stock STI does about 215-225whp on this dyno.

They're close to 300 on a dynojet, but not on a low reading Mustang on 91 octane.

This tune is on the conservative side and AFR is around 10.5:1. That's why the injectors are close to maxxed out.

In general, this car made less power than I expected and have seen from similar setups. Granted, the intake temps were around 105-110* by the end of the tune, but in general this kind of setup makes about 270-275whp and 290-300ft-lbs. All cars are different, however, and once in a while you get one that doesn't make quite as much as it should.

Strange considering that a stage 2 06 WRX will run IDC's around 75-80% depending on the tuned AFR. The only way I could see a 20G running ok on the stock injectors is if its tuned to around 280whp.

An upgraded fuel pump isn't going to do squat unless you are already flowing more fuel than the current pump can handle. Your IDC's shouldn't change simply from adding a fuel pump. Your AFRs may change if you were outflowing the pump, though.

I am considering:

1: a different intake

2: Heat wrapping the intake with some ThermalTek wrap and silicone spray that I have. This should insulate the intake and keep heat out...in theory

3: a road tune, for more reason than I can list. *kicks self for not going this route in the first place*

I am going to check again for leaks, and any other issues. I am hoping there is an issue, and my car is just not below the water line :(

Hey, I'm right there with you in hoping I find something. I had Ed tune my car a few weeks ago, and he said my stock turbo was spooling unusually slow. I swapped it out, and same result. Now I am on a quest to find something wrong, and just like you, hope my car just isn't one of those ones that are below the average. Good luck to you!

I'm 95% sure you have a pre-turbo exhaust leak ;).
