With alot of help from some good friends the aftercooler is in. Will post some pics and dyno sheet soon.Yesterday the truck put down 511 rwhp 421 tq at 11.5 boost.Can't wait to go to the track! The AF/C setup was designed by Meach13 , he also does the tuning and the pipe work on the engine, just to name a few things. Two other friends Jerry & Rusty helped an awful lot with numerous things.

TIRBRNR is that a 5.3?What kind of numbers were you making without the intercooler?With 511rwhp you should be in the high 11s.

the truck is a 5.3 it was on pump gas not sure how much the aftercooler added but last time at the dyno made 425 we took off the fmu added some timing and added the aftercooler we were tired of having to run 100 octane with 11.5 psi to keep it from pinging so now we are on pump gas

Very nice numbers. Are you running an air/air intercooler? Do you have any pictures of the setup?
