Next wednesdey is the big day for me. I know that the dyno is a dyno-jet and I am hoping to hit 285 rwhp. I have a 2000 5.3 rcsb 2wd with a Borla exhaust, super chips tune, asp pulleys, kn fpik, and free mods, do you guys think I will hit it? I will notify you guy what I hit, I want to do a before and after when I install a cam.

 

I dynoed 262/309 when I had nearly the same mods as you (Magnaflow/K&N GenII/ASP/HPP3/freemods). With the addition of Hamm headers, true duals and a sketchy edit tune I went 280/304. Just recently I did 300/305 with a much better tune and 2k vette cam. Hoping to be close to 360 after the heads/cam go on.
All of my runs were on a Dynojet so depending on what type you are going on, your numbers could be significantly different.

 

I'm guessing 255-265. Let us know.

 

mine with a stock LS1 motor did 276 rwhp
