lets put this to bed. I own a 4G GT Eclipse. That 290hp is at the crank. With my K&N Typhoon intake, Magnaflow exhaust, Headers, and an AEM Fuel Ignition controller, i've dyno'ed at 277whp/256ft/lbs. With all my mods and RRE motor mounts + Ingalls TQ damper, I ran a 13.6 at sea level. Torque steer is AWFUL, the front tires have traction issues, and the tranny sucks. RIPP has a supercharger system that uses a vortech V5 blower that makes 450whp/344ft/lbs, but everyone that has one are too bigga ******* to run them at the track. Do not talk shyt about a car you know nothing about for those who were, its a great car, I love it. But it is not a Z by any means. There is ZERO aftermarket support for it, and the headers and big power makers are custom jobs, meaning mucho dinero, the headers are $1200. But no chance in hell will it challenge a 370, 350 maybe.
