Half second quicker than YOUR stock time, or some magazines stock time? Just askin, cuz 2 hp is worth about nothing in the 1/4 mile. Even if you want to consider it a 2% increase, that means you would cut .35 of a second off you're time, all things being equal...but if you happen to have a slightly lower temp, or a slightly higher tail wind, or a slight change in relative humidity, or a slight change in tire pressure, or a little more or less caffeine in your quick twitch system, or a stickier track, or a slightly higher rpm launch, or just Zeus helping you, going a half second faster than 17.856 is like a 350 lb chick losing 12 lbs, she's still fat...

An aftermarket lightweight pulley doesnt give u more HP, it just revs up faster thus giving u faster speeds....
an exhaust will give u hp gains thus more airflow, so will a muffler.......

can anybody post some dyno results of before and after an exhaust mod? I'd like to see what the gains are, and what if any losses there are at low rpms...thanks.

Faster revving will not get you to speed faster, only more wheel HP. And it definalty will not let you go faster - thats either a function of HP and drag OR transmission gearing. Faster revving will give you better throttle response and worse shifting till your used to it - revs will drop faster too, less mass=less kinetic energy. |
