Did he say he is running 18 psi on his turbo??? HOLY CRAP!! I think that a stock WRX STI runs like 12, and that pushes 305 hp, which is the most for any stock 4 banger out there. When I was car hunting I found a 2010 v6 mustang for 17,766 $....But they arent so hot in the snow (rwd) so had to go with the 6. The 6 has 14 more hp anyway (weird how the 4.0 liter v6 only pushes 210 horsepower when the 3.5 liter 07 G6 GT pushes 224 and gets better gas mileage). THe only thing is there are so much more performance mods for the v6 mustang...does anyone know how much they can hold for psi on stock internals?? probably more than the 6!
