Boost Addict's 08 WRX Project - 233whp/334wtq - Pics, Vids, Dyno
wow dude, your car is looking SICK! The blue foot wells are clean, nice splash guards, grille, lip, and intercooler. Did it just bolt up directly to the turbo with no Y Silicon Hose???

Turning into a great build. Pics blocked from school computers because of photobucket, but the numbers are good. Maybe my '08 WRX can get some attention like this later.

I did my best to select small, yet effective parts that would stand out to a tuner but not look overly excessive. The intercooler is a direct bolt on(and yes, direct bolt to turbo). Fitment is great, but for additional clearance, I removed the plastic cover that hides some of the wires between the intake manifold and the intercooler.

Without tuning, I'd have to say no, as there is a pretty significant pressure drop.
Right now, the car is pulling too much air over 100 mph, and that's why we're hitting boost cut
We may have to manually bleed off the boost. To be honest, I like knowing that flow is not an issue.
Going to order the Walbro 255lph pump and DeatschWerks 750cc injectors tomorrow, most likely. So within the next couple weeks, we will see what we can accomplish.

I've already achieved the goal I set out for in terms of power. We are now adding 750cc Deatschwerks fuel injectors and 255lph Walbro fuel pump to have some headway when we retune the car for slightly more power. We are done seeking torque, as I don't believe the factory drivetrain would appreciate any additional force during launch. We may shoot for a little more boost, seeking slightly more high-rpm horsepower to further improve highway acceleration.
We are very happy with the potency of power. Next on the list is a more comprehensive approach to the suspension of the car, as we feel the chassis has a lot of potential while the springs, shocks and sways are falling short of the task.
----------------

~3700 rpm launch, feathered the clutch during a full second of modulated wheel spin (0.60 seconds to 1.70 seconds), Shifted to 2nd gear at ~6750 rpm. Lifted half way between shift, did not rush gear or flat foot shift.
This time can be shaved down at least a couple tenths with better grip, quicker launch and faster shift.

I'm expecting maybe 5-10 whp additional in the top end, so really it's more of a reliability/longevity measure more than it is a quest for more power. Also, it's a very inexpensive modification. Approx $120 for the walbro 255 lph pump and about $200 for the 750cc Deatschwerks injectors after you send them back your cores. Of course, the re-tune is costing me more money, but if someone does the injectors first, then they won't have to keep retuning the car. We are tuning it step by step, just in the event that someone doesn't want to run the upgraded injectors and pump.
