PERRIN STI Equal Length Header

Updated from July 2010 post with new pics and new data! When Subaru released the Version 8 STI in Japan we noticed how they moved to a twin scroll turbo and equal length exhaust manifold. This is what inspired us to make our first header for the WRX/STI! Would taking the equal length design of this JDM header and adapting it to fit our US cars actually make a difference in power? Would it spool worse?  How would the sound [...Continue Reading...]

Cone Tunes For The First Time

When you email tech@perrinperformance.com, or need help with an AccessPORT map, or ask for help with installing your PERRIN Radiator Shroud, you get Cone.  Chris Cone that is. Chris handles all the AccessPORT customers along with all the general tech stuff.  Chris is 100% a car, guy but never actually tuned a car on the dyno. Over the years he started to pick up on why we tune things a certain way, and started to understand some of the basics [...Continue Reading...]

Project 15K, final test & tune 300WHP

Project 15K started life as a $10K 2002 WRX we purchased to show people how you can get great power from the older 2.0L cars.  The project car was purchased with a lot of miles, but also a few mods already done.  The Blaze yellow WRX had a catback exhaust, catless downpipe, huge diameter uppipe (huge is not a good thing) Version 1 AccessPORT, lowering springs and not to mention a sweet grounding system using  8 gauge near solid core [...Continue Reading...]

The Great Subaru Intercooler Test

The Great Subaru Intercooler Test Its intercooler testing time.  After a semi cold winter, it was a great time to do some long awaited intercooler testing.  Because our 08 STI has become the mule for testing of other parts, its great for testing intercoolers.  We have great results from previous dyno runs to back up the consistency of the power (or lack thereof with stock intercooler).  Like other dyno sessions, we started with the same map and same dyno setup, [...Continue Reading...]

08 STI Intake Test and Tune

This test was done on our 08 STI shop car.  Before we get to far into the fun stuff, the STI is in our Stage 2 form. This means it has our twin cat downpipe, 3€ quad tip exhaust, and our Stage 2 AccessPORT tuning.  With that said we are going to show 2 tests in this article one, the PERRIN 08 intake and the PERRIN  Version 2 inlet hose. First lets explain the dyno and testing methods we are [...Continue Reading...]

PERRIN Turbo Inlet Hose Evolution

The PERRIN turbo inlet hose has been one of our best selling, long standing products for many years. Since the beginning, we have made our part different than the rest in that we didn’t just make a copy of the OEM part.  We had something different in mind to make the installation of this go much easier, and also out perform other turbo inlet hoses offered by our competition. HISTORY LESSON When we got the WRX and started making parts [...Continue Reading...]

2008 WRX Stage 1 Test and Tune

After 10 days off, its time to get back to work!  While we made [...Continue Reading...]

40 Miles on the 08 STI and we tune it!

There is not much to brag about, but, now that i have your attention, lets see what these new STI’s put down! The first couple runs showed about what we would expect to see. Most STI’s put down about 230-240WHP, and we were right there. Same with torque, we were pretty close to what everyone sees. Few things to note, redline is 6500, not 7000. WHAT?? Well that is simple, Subaru only needed to make the 305HP mark and it [...Continue Reading...]

2008 STI Exposed

So I am just sitting there responding to some NASIOC posts, and I get the call…… “Your 2008 STI is here!!!” our good buddy at our dealer tells me.  This was a huge surprise to us as we had all been told they would be in by the end of January!  It’s December, and we already got our car.  Time to get to work! When ever we get a new car, the first thing we do is go over all [...Continue Reading...]

Now that Project $15k has a healthy dose of power it’s time to put some focus on the suspension and brakes.   Starting with a car that has 110k miles on it probably means it has the original struts holding things together but not playing a big part in the suspension game any more.  We found this to be the case as they where worn out, rusty and leaking.  The springs have been changed in the past with some cool [...Continue Reading...]
