Proving the PWI-2 Water Injection System

NEEDS TEXT FROM NASIOC     Progressive-ness of the PWI-2 system. The PERRIN PWI-1 system stood out amongst competitive systems because of it being one of the first truly progressive water injection systems. The new PWI-2 is still just as progressive as the older system but it stands out from the crowd for a few other reasons. Less expensive non-progressive systems are simple and cheap, and are restricted to a fixed volume of water that can be delivered.  These systems […Continue Reading…]

Foam Filter Q&A, why they are the best.

Everyone has an air filter on their engine (at least you should!) and this goes true for all types of things that that suck in air constantly.  Yes even you have a filter; your nose has them built into it as does your air passageway.  But we are talking about your car here which sucks in way more air than you do, so it has much more special filtering needs.  Also we are talking about a filter for your performance […Continue Reading…]

ALTA Tensioner Stop Preview

  Introducing the ALTA Tensioner Stop!  While the idea of this part is not new, our execution of it is.  This unique design allows the end user to install the part faster than other designs, and function the same with ZERO chance of failing. Why do you need an ALTA Tensioner Stop?  At some point in your cars life, the serpentine belt that allows the crank pulley to drive the Supercharger and AC, will fail.  When it fails, there is […Continue Reading…]

ALTA R53 Side Draft Intercooler Dyno Proven

As promised here is our data!  Sorry if the formating is a little confusing. Good to hear from Matt, we havne’t heard from you lately. Must be all those MC2 articles! First off, i know understand why there are lots of doubters out there. It could be because our dyno graph wasn’t on our site. When we had an issues with our pictures on the server, this one got missed. On these test conditions, the OEM Intercooler was tested with […Continue Reading…]

EVO X Intercooler Prototype Build, Test & Tune

Like we weren’t going to make a new intercooler for the X. For one, the stock one is pretty restrictive, and two, in order for the EVO to compete with the STI in our EVO vs. STI project it really needed one!  Besides the gains we saw there is one very important thing we found, which will be a Huge concern to all X owners after they find this same thing out. Before we get too deep, lets look the […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…]

EVO X Prototype Turboback Exhaust Build

We have had the X for a few weeks, and in that amount of time, we have dynoed the car in stock form, and dynoed the car with a custom hardwired Unichip. Both have proven to show very good HP numbers, and this is with the stock exhaust, intake and other parts!  Like our other builds we have done, we are building the parts for this car in the direction that we expect most customers to build their car.  So […Continue Reading…]

Turbo Inlet Proving Time!

This is a test you will none of our competition do! We have always wanted to prove that a PERRIN turbo inlet hose was more than just a good replacement for a failed OEM part. We know it makes more power and allows the turbo to spool faster, and there are a few results online, but all these tests were done days or weeks apart. We always wanted to prove how it works and do an install within a couple hours, […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…]
