I replaced the Aeromotive Eliminator and replaced it with a Weldon 2035 and controller

Make any pulls yet? I'd guess around 750 RWHP. Won't guess on the torque, it can measure crazy with an automatic.

Finishing the last of the 3.5" intercooler plumbing right now. Will be off to Jet-Hot on Monday, then dyno after the tubing returns

3.5 tubing is back from Jet-Hot!! Should be tuned shortly...

That Piping looks awsome! My question is there any pro's/cons of going to a piping larger than 3"? Reason I ask is because I'm in the process of installing a Procharged 406 SBC W/D1-SC and I would like to go to custom 3.5" or 4" plumbing. The motor made 780hp @ the crank with the OEM 3" crap ATI sent me. Just wondering if it would be good/bad to step up to the larger piping?

[rtigert]

The are a few reasons that I went with 3.5" over the 3". My intercooler is 3.5" and my throttle body is 3.5 (90mm). If I'd have used the standard 3" sized tubing, I might as well have simply used a 75mm TB and a 3" IC. My thoughts are that it would be like running -10 to your filter - then -8 to your rails - then back to -10 fuel rail.... not exactly the same but, same theory. So to answer your question, I don't feel that a 4" would have gotten me any improvement over the 3.5 since 4" is bigger than the rest of my components and 3" would have been a bottle neck in my system. That is just my opinion.

ATI rates the 3" Universal Tubing Kit at 350Hp less than the 3.5" Universal Kit (950-vs-1350, respectively)

if it doesnt make 850 to the tire your doing something wrong...i also think you should get rid of those 83' ang get some 160's now and save yourself the aggrivation...
