The Subaru Impreza WRX is a power bargain: A quarter-mile time the 13.5 seconds at 101 mph is as rapid as any WRX STI we’ve tested, and also the typical WRX version is around 10 grand cheaper. Being power hungry, we have investigated a number of claims the even much more output—over the share 265 horsepower and 244 pound-feet of torque—is easily accessible with a couple of simple modifications. Together we found, your results might vary. Here’s how we gained that extra power:

Getting an ext air right into the engine’s combustion chambers produces much more power, right? Right. After ~ a basic installation, the low-restriction conical wait filter and straight intake pipe of the k & n Typhoon kit (800-858-3333;

STEP 3: But they Don’t add Up

We put our project automobile on a dynamometer through the k&n Typhoon intake and the Magnaflow exhaust (the numbers mentioned previously were accomplished with each performance piece installed solo top top the WRX). V both installed, horsepower to be up by 11 over stock and torque was up 20 pound-feet—increases the are less than those developed by the modified input alone. The extra air flow on both ends was apparently too much for the factory ECU to cope with, and it compensated by cutting power right when the turbo reached maximum boost. Either the entry or exhaust functions fine alone, yet ECU changes are compelled to acquire them to work-related in tandem.

So, to get even more power, we had the engine reprogrammed. Remember, that voids her powertrain warranty. We called Cobb Tuning (801-713-0035; www.cobbtuning.com) because that its AccessPort, i m sorry can fully revise the engine software. And also to further free up the exhaust, we threw in a Cobb downpipe with a high-flow catalytic converter. The AccessPort connects to the OBD II plug and also automatically saves the manufacturing facility engine programming. It likewise has preset engine maps for assorted states that tune, but none the accounts for an aftermarket intake. Cobb says there are too countless variables to have actually a single program, for this reason we gained a $460 practice engine tune. After that, wheel horsepower to be up 57 to 266, torque increased a staggering 68 pound-feet come 293, and now the engine sound meaner than Sasquatch’s wife.

We installed a collection of higher-performance Bridgestone Potenza RE-11 (www.bridgestonetire.com) tires, swapping the end the stock Dunlop SP sport 01s. Skidpad grip increased from 0.84 g come 0.87 g, with a noticeable reduction in the understeer that plagues the stock WRX.
