Message: [QUOTE="Mwilbur516, post: 457491, member: 784"] Adam, I agree that one dyno run doesn't prove a number. Here's where I disagree, you say that Chris's truck puts down more power than most when in fact my truck put down 485rwhp with the same setup and same turbo on PHP's dyno with a tune designed for the stock turbo on a much hotter and more humid day. The status quo has always been that stock injectors were maxed out at around 450rwhp. I think with advances in tuning, FICM tuning and more turbo options that really work, bigger numbers are possible for a lot of guys. There really isn't anything special about Chris's truck, my truck or any of the other trucks that have made bigger than "normal" RWHP numbers. They have just been well taken care of. I'm by no means trying to start an arguement, just voicing my opinion. I think we're gonna start seeing more trucks close to 500 on stock injectors with and without MTW turbo's. I believe you need a healthy fuel system, as much air as possible, healthy HPOP and some good custom tuning (SCT and FICM) to get to where we are. These trucks are consistantly making more power and now we did it on a different dyno as well as planning to back it up at the track whenever we can. I will say that IMHO opinion, 500 or very close is probably gonna be the most we can get out of stock injectors. This is all my opinion, so please take it for what it's worth. BTW, just to clarify, when I say, "you need as much air as possible" I mean that within reason. You can't throw a 78mm on an otherwise stock truck and expect 600+. You need to be big enough to move the volume of air required to max out stock injectors and still be small enough to spool and be be drivable. [/QUOTE]
