Message: [QUOTE="madpowerstroke, post: 619514, member: 5867"] I wasn't implying anything but that bashing a dyno operator, whether number are right or not is the way to go. I would have stayed on here and posted more replies but I just got done with my truck and building a bunch of turbos. I did say if there is a problem with numbers then take it to the track. As far as I know a 6.0 and even the 6.4 don't do well on a unloaded dyno. That is if the truck is running the vgt setup, the ecm works with the transmission and knows when it is loaded to keep vanes closed to make boost. Now when you go to a non vgt you take the ecm out of the pictures for controlling the vanes so what you make is what you make. The vgt controlled by the ecm is a pain in the a** to get it right, Bill at PHP dyno'ed his truck the night before he left and was tuning for the biggest numbers he could on a loaded dyno. His number ( please just repeating what I was told 570rwhp with 175 stock injectors and a hybrid, not wanting to argue on the numbers ) at Rudy's he hit 405rwhp so which one is right or wrong, take it to the track and find out. Now Bill will take his truck to the track so lets wait and see what he does. Like I said before dyno numbers can be good or bad and are a tuning tool, but track numbers are what the truck can do. Ok enough with the derail, I finished my truck and took it out to see what it would do. The truck runs very strong, but sadly didn't get a chance to hit it really good. Blew a boot but was well at 40-45 psi when it did, I was getting on freeway on ramp nail down 1/2 throttle and the truck got side ways at 50mph, had to back off bring it up to 70 and crushed it hit 40-45psi of boost and pop. Got it back home and going to hair spray and button everything up tomorrow for another run. I need to get the tune updated running 2 psi of boost at 70mph with 39% VGT duty cycle. Egt's are a little high due to the boost being too low. The difference between the truck before and now is that I have 1.5 mm bigger exhaust valves, lightly ported intake and heavy ported exhaust. So what did I noticed so far, the turbo spools extremely fast, once I get the tune tweaked a little It should really wake the truck up. The truck rides really well now, and feels tighter in the steering. I want to go to Prude dyno event but I might pass on it I have some more things I want to do to the truck and not sure to do it before or after. I have a custom paint job I want to have done to the truck and don't know if it would be done in time. By the way I know the boot poping is a excuse used before by a ex member that I will not say his or her's name, but really it did pop on me, not saying that it makes near the power of un named ex member, but I will fix it so it won't do it again...........LOL .......Don't make get my lawyer.................I need gas money........... sorry couldn't resist [/QUOTE]
