Hello All,
I wanted to start discussing my progress in tuning my 2005 WRX wagon. My current mods are:
Engine
- APS SR30 ball bearing turbo
- Titek catted downpipe
- Borla Hush catback
- Modded injectors (740cc)
- GM boost control solenoid
- Opensource tuning using Romraider
- TinyWRX Launch control patch
- Boost Cooler MeOH Injection Kit with 63mL/min nozzle and VC-25 controller
- Innovate Motorsports LC-1 Wideband O2 sensor
Chassis and Suspension
- 22mm rear swaybar
- Perrin anti-lift kit
As far as tuning goes, I am running 20psi of boost. I run 10.9 AFR and 14 degree timing advance at peak VE (3200 RPM.) I don't run at the bleeding edge of knock since this is a daily driver and it's fast enough for me. I have yet to dyno the car, but hopefully I can take it to Road Race Engineering if Santa thinks I was good this year.
The car definitely feels faster than stock. The SR30 turbo flows about 460 cfm at 18 psi, so it is on par with the more common IHI VF22. The GM boost control solenoid works much better at controlling boost spikes and sits rock solid at target boost all day.
I am in the process of tuning for my methanol kit. From the research I have done, (and logging results from my wideband), At full load, 50% water/methanol shows up half a point richer when injected. Anyone have any tuning experience with MeOH?
I will try and post up fuel timing, and boost logs as soon as possible.
And if anyone is wondering this is the ugly silver wagon that shows up at Nick's.
