So I get on 295 today heading home when I get approached by a pontiac G8. So I'm thinking sure pal go ahead and try....which is when I find out its a gxp equipped with a 6.2L LS3 V8 making over 420hp from the factory shifted by a TKO600. I had em until my car ran out of top end at around 130mph....is that a limit....I remember doing 120-125 without the blower. Time to start planning my next engine.....Dammit!
