Just wonder how well you guys are flowing at WOT. I have been testing different setups on different N/A trucks to see how they compare. I think im breathing pretty good. (how much does air way?) The areochamber seems to flow real good compared to the hi $ Gibson. Each truck had a 220/220 112 cam.

My 99 EC/SB 5.3 stock was 30 lb/min
After cam, LT headers, ORY, Cutout and Magnaflow system 42 lb/min

04 5.3 CC, 29 lb/min stock
Cam, Gibson Shorty headers, cats and Gibson cat back 32 lb/min

02 5.3 EC/SB 29 lb/min stock
Cam, LT headers, cats and Areochamber 36 lb/min

I think I saw about 58lb's on the Av., flow was pretty much maxed out at 11,000+hz.

37 lb/min on my 99 ecsb Z71 w/Z06 cam. that was on my Nelson tune. I dunno how much I am flowing since I tuned my VE tables, I had to add to the higher VE values so the numbers up top are probably not much higher, if not a bit lower.

Your truck has a lot of potential, wait until you dump that maf and get it tuned up nicely!! It's gonna fly!

Not quite sure I can envision 6000lb shoeboxes that fly, but there is one thing that I know for sure...the Goodyears never stand a chance anymore..... :cool:

Can't wait to get started on the 2 BAR SD... I already have the PID online in HPT waiting on the input....

63.09@5380 rpm I have work to do still. I am trying to get it scaled correctly and chase down some KR.
