Making an official thread for all of our viewing pleasure. Seeing as how I can't be there to razz on you about how F'd up your cars are because I'm working.
Let's see 'em. Discuss.

Went from this back in July of last year:

To this at the dyno day:



Car:

2004 STi

Mods:
catted TBE
740cc injectors
255L fuel pump
2 step colder plugs
wastegate actuator

My car was knocking and the dyno plot was all over the place, not smooth at all. Hopefully its nothing internal causing this. I'll have to do a compression and leak down to make sure my motor is ok, then maybe check the injectors, spark plugs, and fuel pump. I'm praying its just something a retune will take care of.

Thanks GST for hosting this event.

Wawaweewaa. That badboy is in rough shape. Did you get a chance to talk with Mike about it? Noticed any knocking prior to today. It really looks like it's struggling to put fuel in. WHy the 2 step colder plugs? Did you have the two step last year?

Everything was fine up to maybe a couple months ago i noticed a little rougher idle and some struggling at full throttle on the freeway. Everything was ecutek tuned in July so all the mods were on the car when it got tuned. I'll get my fuel system checked when I get a chance. The tune was solid when I got it.

Mike was really busy today so I talked to one of the other GST guys about it. He recommended the compression and leak down and a retune. Hopefully my motor isn't damaged and I can fix this with some new fuel system parts and a retune.

I dont have a tune yet so definately not where I want to be: 04 WRX with TBE and Upipe. Perrin Short Ram intake. My car was running really rich.
196.8hp
192.6tq

GST said if I give it a tune I will see 215hp. So with that I would be happy.

196hp
198tq

AFRs dropped to 10.2:1 so I'm running crazy rich. Previous owner had it tuned but I guess the tuner was crap. Drove it home and started taking crap apart.... evo3 16g, walbro FP, ebay TMIC, 865cc injectors, 3 port boost solenoid, and TGV deletes are all currently going on.

I was amazed at the numbers the BRP RS put down:
133/14x

And couldn't figure out why, and I just looked at my dyno graph from Dec 2005, and noticed that my headers gave me exactly 3whp at peak... which explains why his non-headered car made 3whp peak less than mine. The header made power in the mid-range where I need it most, so it makes sense that he made the above numbers. Just proves how badly the NA cars need more agressive cams to make any real power at all.

Here is the last dyno graph i have for my car.

Yeah, showed up around 10am and left at 12:30 or so... I had to get someone back by 1pm.
I didn't see you there. Do you still have my stock headlights?

Hmm I wonder if the reason we got so many leaners, is because the winter gas blend.

yeah, that needs to be retuned. 10.2:1 AFR isn't bad, but with that setup you should be making a lot more power.

Back when I was running an EcuTek tune by Mike in the gruppe-s days, WITH my stock third cat, uppipe/shorty downpipe, 2.5" catback, I made 201HP/204FT-LBS. on the very same dyno.
