Kenne Bell (Just) installed a Kenne Bell 9 PSI Intercooled on an otherwise stock 04 GT convert. Sub frame connectors, boost and fuel press gauges only other mods. KB claims not much HP gain with exaust mods on the '04. Brakes probably next. Under normal conditions, you never even get into the boost, 10 to 20 inches vacuum pretty standard. Drives like an 260 hp GT, but quieter, (the plastic PI manafold is replaced by a massive hunk of aluminum) Wouldn't even know you have access (claimed, yet to be dyno-ed) to 427 lbs and 405 HP. At about 2000 RPM WOT hits 7 PSI, at 6000 RPM WOT is a little over 10 PSI. Awesome acceleration from 2500 to Redline, Torque curve flat as Nebraska. More expensive then the hair dryers, however, kit close to 5 grand $$. |
