What's the maximum realistic HP/torque possible from a street driven V6 car? What have guys built those engines up to power-wise?

 

My built block 4.0 was running consistent low 11's and a 10.9 before I threw a rod.

 

What kind of HP/torque was that engine making?

 

I'm not a dyno sheet kinda guy. But it was making 535rwhp/600rwtq. Here is the mod list:

Hey rygen,

Impressive numbers/results for SURE! But at some point while modifying your 6-banger SO extensively did you slap yourself on the forehead and say "****, I coulda had a V8!"?

I mean, you can BUY a V8 with 500hp... but I guess you'd say "Half the fun's getting there."
