nice numbers!! man, i wish i could get on the dyno. bigger turbo, better heads, and bigger cam. et calc says 630ish to the wheels but i think its more cause my 60ft sucks at the track.

 

wow sick numbers bro. Easily close to 600 on a couple more lbs. I made 550/550 on a 5.3/MP70/too big cam lol. So yeah these numbers pwn me.

 

thanks for the comments fellas, still waitin to hear from ed. i was hoping to pick it up today, but we'll see

 

is this on stock pistons and connecting rods..?

 

You running meth too or just straight pump gas? What year LS6 cam?

 

stock everything except ls6 cam, lifters, 7.350 pr, valve springs. Pump 92 gas, converted to return style system with 255 intank and bosch 044 inline, 72lb inj, fast rails, aero boost ref fpr, -8 feed, -6 return lines

 

oh i forgot, tbss intake 90mm tb and NO METH

 

I've only seen one other guy with more power on a 5.3 than you. His numbers were only marginally better than your power estimates, and he was around 20psi... Damn respectable for so few cubes

 

what kind of heads you end up with? still havin traction probs with awd?

 

Great numbers MGMC. That thing is going to haul ***.

There are a few guys on LS1Tech running in the 7XX+ on 5.3's. Rick at Synergy Motorsports ran 848/821 on his stock block 5.3l/317's/4L80E/22X cam @ 18lbs. See post #43.
