2/18/2005 By: Chris Neprasch In the first three parts of the WRX series we have mainly focused on what’s under the hood of our Subaru. Making power is only one small element of being successful on the track though. We took the WRX to a local autocross event with allContinue Reading
2/4/2005 By: Chris Neprasch It’s no secret that the cold air makes more horsepower than hot air. In turbocharged cars this creates a problem since the turbo itself is powered by exhaust gases exiting the combustion chamber. Explosions don’t create cool gasses so the more you can do to bringContinue Reading
2/4/2005 By: Chris Neprasch First off, catalytic converters help keep the environment clean. You’ll get in big trouble with the authorities in some states if you ever get caught on the street without them and they help lower emissions so much that Subaru put three of them on the WRXContinue Reading
1/28/2005 By: Chris Neprasch Our latest mission is to turn a stock 2004 Subaru WRX into a car that can handle its own during local track days and on the autocross course while still maintaining enough civility to be a reliable daily driver. This means no huge turbo setup thatContinue Reading
1/20/2005 By: Roger Hewson Fuel injectors are one of those things most people understand, but at the same time they don’t. Obviously a fuel injector sprays fuel into the motor so what makes some injectors better than others when it comes to reliability and efficiency? There is not a lotContinue Reading
1/13/2005 By: Roger Hewson Heat is detrimental to performance; it’s the entire reason behind cooler thermostats, front-mount intercoolers, cold-air induction systems and everything else on the market today designed to cool down something under the hood. Colder air being fed into the engine makes more power and that’s the reasonContinue Reading
1/4/2005 By: Roger Hewson I was going to start this with a cliché “nobody likes dead batteries” statement, but any idiot knows having a dead battery sucks. For a motor to run it actually has to get going first and that is where the all important battery and starter comeContinue Reading
12/22/2004 By: Roger Hewson Clutches and gear ratios are a couple of the most misunderstood aspects of tuning out there. From terminology to setup to how it works, we have not come across anything more mixed up, applied wrong or just screwed up more than these two applications. It’s whyContinue Reading
12/8/2004By: Roger Hewson It’s no mystery that stock exhaust systems stink. No matter how good it might look or sound, there is something somewhere on most OE systems which makes them worth replacing. If this was not true we wouldn’t be writing this story, or the countless other exhaust installContinue Reading
12/1/2004 By: Roger Hewson A lot of ground has been covered in the first two installments of You Need To Hook It Up. Part One covered how important chassis dynamics and weight distribution are and after Part Two everyone should have a better understanding of how important tires are toContinue Reading
