Definitely unorthadox without tuning and such, but interesting findings:

Hey guys,

We've been busy over here at Ultimate Racing working on our new satin white pearl 08 WRX.



A couple of weeks back we posted our initial stock dyno runs. Stock dyno numbers were great, and gave us a good idea of the potential of this new engine/turbo setup.

As with earlier findings by PDXTuning, we found that the 08 does indeed share the odd tuning traits of the 06+...AFR's stay lean well into full boost (~12psi), rich on top, with plenty of timing/afr dips. We, as well as many tuners we're sure, are eagerly awaiting EcuTEK's support for these 08's because this engine can definitely benefit from it! However, we were unsure how long this would take, and were all pretty bored of the 08 WRX in stock trim. So we began to mod.

First up was a simple Cold Air Intake. I know, I know...intake pipes generally do very little on Subaru's. But what if I told you that we made one that actually does something! It seems the 08 can definitely benefit from a good, free flowing CAI.



Keep in mind that all of these dyno charts are the result of bolt-on parts, no tuning, but with AFR's, and Timing being monitored closely to ensure safe performance.




Next up, obviously, a good free flowing exhaust. We decided to do something a little different than everyone else....build an exhaust with minimal bends, and the quickest possible exit. We used a 7" round muffler that's completely straight through. The 7" round design will help keep noise tolerable, while still retaining true straight through performance. We decided to angle it, as to save on bends (Don't worry guys, you'll like the way it looks from behind). And guess what? It's pleasant sounding too






These were the results of our Turboback exhaust (with high-flow catted downpipe), and CAI




Last up, a good Front Mount Intercooler. It's safe to say that NONE of the existing 02-07 FMIC kits on the market are going to fit this car. Here's our version. Reverse Flow the way everyone likes it.



This dyno shows the CAI, TB Exhaust w/ High-Flow Cat, and our FMIC kit.




Again, we are very pleased with the 08 WRX. It seems like a solid platform for power. Of course, we'll have to wait for EcuTEK before we can really start pushing the envelope. GT35R anyone?
