Just to share with you people who are interested in upgrading you brake Muscling up your ride with more horsepower and torque is always thrilling, but take the car beyond what its braking system can handle and you risk ending up with a heap of scrap metal, or worst still: in it. With many cars manufactured with competitive pricing in mind, you can bet your bum that your car's stock braking system is only as effective as it needs to be handle the car's original power. While that is fine by most car owners, those who are speed junkies probably need to an upgrade here. How Does It Work?

I wasn't really interested that time cause my car's engine is still original 4G15. Due to some cancellation on my schedule, I'm kind of free after I make a delivery to Sandakan, Sabah. So I decided to give it a try to see how much HP my old junk can churn out after spending so much $$ on it. For your information, a stock 4G15 generate about 89bhp/75whp at 6000rpm, 126Nm(engine)/107Nm(wheel) torque at 4000rpm . Since I drove my car, I've been stuffing stuff into my car with the hope of improving it's performance. This first run after all the mod so far churn out bout 95.6bhp/83.13whp at 5500rpm, 143.3Nm (engine)/124.62Nm (wheel) at bout 4000rpm . Final/5th run after some adjustment, the engine manage to spit out 99.5bhp/86.58whp 5500rpm, 147.15Nm (engine)/127.96Nm(wheel) torque at 4000rpm . A total of increas
