However, our inductive rpm pickup has been a little problematic of late. Heck, when I was running your car at wastegate boost and with richer fueling at the beginning of the tune the tach pickup was still flaky up top.

Paul, I'm not knocking your tune. No pun intended. I know you were very thorough with my car and took a lot of time checking the logs(and getting rid of the AVC-R) and you totally transformed the way the car felt from before the tune. Something like 15 pulls on the dyno is pretty freaking sick for just one map, last time I got tuned for 4 different maps I didn't get that many pulls. And thanks again for taking the time to do the road tune afterward, the car is running really smooth. I will definitely recommend you to anybody looking to get tuned down here.

Murrdogg24, do you have any plans for a few passes at the 1/4mile? I'm just wondering what those numbers would do for your trap speed. I'm thinking at least 108. Did you get launch control setup? If not its just a patch and you can download it for free. i patched my rom and have setup a conservative 4500rpm launch speed. At that rpm it still smoked the front tires pretty nicely.

Not planning on doing any drags because I'm on the stock WRX 5 speed and don't want to explode my trans right now. I mainly just do auto-x occasionally. And the fact that San Diego doesn't have a 1/4 mile strip, they have a lame 1/8 track.

cool beans man, its a great setup and i'm sure you recognize that already...I'd love to try this motor with a 6spd, probably revs and shifts are so quick, like a crotch rocket

On a dynodynamics I pushed 308 hp/291 tq WITH a 1.15 correction factor, so about 268 hp/253 tq
mods were basic stage 2- catless turboback and ebcs.

I will say tho, it pulls MUCH better than when i had an ej205 with the same basic "stage 2" mods
At about this point you'll get injectors, how far can te pinks take you?

Iirc , I maxed out my pinks around 320+whp @ stock fuel pressure WOT.
I believe they can flow a bit more if the pressure was bumped.

I remeber a really old tread, where some of the tuners on the board were discussing with Simon Lines from Prodrive about maximum injector duty cycle and how you can still get meaningful flow increase beyond 100%.

I know about this because I ran Prodrive Stage III for 5 years and my duty cycles were logged between 90-102%.

The explanation turned to be that the IDC is a reported value, in the software, not the electro-mechanical pulsation frequncey itself.

So, where I am getting with this is that when you say maxed out, you mean that the duty cycle is around 90%+ and you still feel confident that you have at least some headroom left (for a cold weather boost spike), to where you will continue to run the pinks unmodified for a long time?

This, of course, unless you mod for more power meanwhile.

I am asking because this is my current power goal and I think that a twinscroll EvoIII 16G with a 10sq cm exhaust housing and 11 PSI actuator will take me there.

OK so i FINALLY got around to tuning

i made 321 AWHP and 283 Max torque on my stock ej207,

Power was at it highest at around 5500 rpm which SUCKED but the curve and power delivery was extremely smooth and linear.
TOMEI TS 7760 -Arms (twin scroll)
EJ207
Aquamist meth/water 50/50 with 1mm injector
Light weight perrin crank
PE800 dual injectors
3" zero sports Exhaust with similar down pipe
Bigger in-tank fuel pump
ECU-tek

all in all it was very disappointing power from this turbo. Its very laggy in comparison tot eh stock vf37 although where it makes it mot power from 5500 ALL the way to redline is perfect for midrange- and when shifting your rpms should be around here so you will more or less always be in power band.
considering trying the Litchfeild over this tomei.

any thoughts ?

Here's a thread I started on different twin scroll options.
http://forums.nasioc.com/forums/show....php?t=2170999

I had considered the Tomei, but the results I had seen were poor, and this further confirms that. Feel free to post up your dyno graph both here and in my thread.

I plan to get a Kinguwa twinscroll piece when I do a Version 8 swap.

I just saw this. That sounds really high! Do you have an oem transmission?

Thanks

My brothers bugeye was the same way. Like 3 grand at 65mph. My bugeye (same year etc) could do 70 at about 2.9k. I have no idea why exactly, but ive heard depending on the date of manufacture the bugeyes came with differently geared trannys, but I have no proof of this, only practical knowledge

^ I've never heard of that. I thought all 02-03's were geared the same. ...and I thought that gearing carried over until '05 or so. I pre-ordered my '02, and it had the same gearing as the '03 tranny I swapped into it a couple years later. I wonder if some of the early '02's came with 2.5RS trannies, and I just lucked out. It might be worth cross-checking what gearing the '01 2.5RS came with, to explain the high cruising rpm.

If you you remember back to 02, Subaru thought they would sell 5000 cars. They sold 15,000. Lots of the 02s had odd ball parts. My 02 had a different 5 mt trans. The tag came back to a v6 STI 5 speed. Its entirely possible that your car had different trans then others.

I looked into neutral switches. The old, direct polarity is part number 32008AA103. This is needed by the people that have a 2005+ WRX body and get a V7 or 8 EJ207

The newer, reverse polarity switch is needed by those that have a 2002-2004 WRX body and get a V9 or newer EJ207. This is part number 32008AA150.

Of course the patch for reverse polarity can be done too, I'm being told.

Very interesting. If I still owned either of those cars I'd find the tag and look it up, got me curious.

About tuning the twinscrolls:

WIth the OEM oxygen sensor now in the downpipe and readings not skewed by high pressures like in the exhaust manifold location, is it still necessary with the twinscrolls to have a separate wideband, or is there a patch to remove the AFR clamp on the stock O2 sensor and use that as wide band?

RE: single scroll options.


Has anyone tried the 18g-xt or similar on a 207? Thoughts? Tried searching the thread but phone searches aren't great........

I decided to replace the switch and fix my AVCS. I had to change plug as well. the harness plug differs.
The continuity is clearly reversed.
My AVCS started to work right away, really nice.

My oil pressure in idle seems to have increased very slightly.

I put together the remaining parts into a neutral switch for use by people with V7, 8 and 2005+ transmissions.

The car pulls really nice now..

Ok guys I really need an empty ej207 shortblock all I need is the case. The catch is, I want it to be the stock bore with no damage. I cant justify building my block with a .40 bore. Someone please help me out.

Aren't the 207 and 205 cases essentially the same?


I may be completely wrong btw...
