***Edited post to correct info***
From some info ive read on speedys blog Project SportRunner he had his dyno'd with 7th injector and 2.2 pulley. He put down 240rwhp and 260rwtq. Assuming 20% drivetrain loss that's 288hp and 312tq at the crank.
Now to compare those numbers to a stock V8 4th gen you'd have 235hp and 320tq for 2003-2004 models with non VVT-I. 2005-2009 offer 270hp and 330tq. Both V8 models offer the 5 speed auto trans which is probably much better than the more sluggish 4 speed auto in the 3rd gen.
so all seems somewhat comparable according to just numbers, although 5 speed automatic probably makes quite a difference.
3.4L V6 supercharged with urd 7th injector and 2.2 pulley
288hp and 312tq at the crank - 240rwhp and 260rwtq at the wheels
4.7L V8 stock 2003-2004
235hp and 320tq at the crank - 188rwhp and 256rwtq at the wheels
4.7L V8 stock 2005-2009 VVT-i
270hp and 330tq at the crank - 216rwhp and 264rwtq at the wheels
any dyno charts showing those numbers?
it would be interesting to see where that power is, compared to the v8.
