    2004.5 Dyno results

    2004.5 Dyno stock fuel stock turbo.jpg

    Here is my first trip to the dyno, 442hp and 883lbft. Truck is on stock cp3 and injectors, stock turbo, stock head bolts. 3000uS, 28* timing, 160Mpa, and 38psi psi of boost. I guess my question is, how hard are you guys running stock trucks? I feel like Im just about at the limit of what would be considered "safe" but then again I dont really know. More room to grow with tuning, or does my next step include hard parts?

    I'd run it harder, 3200uS, 32* timing, 180Mpa. Just for the big tune. I don't run that high of pressure on daily most of the time. Let that old girl eat! No hard parts needed yet.

    Oh man. I would not run that high of boost consistently with stock head bolts. Just asking for trouble. Not saying you can't, but why risk it? I always play the safe side though. I dont like much over 32 psi on stock bolts.

    Head bolts and my converter are really worrying me at this point. I work at a transmission shop and Im building a 48re with a billet input and triple disk converter as we speak. As far as the bolts go, im going to throw APR studs at it when I get the money for a s463 second gen swap. Next time Im on the dyno I might give it a little more rail pressure, duration, and timing like Dom suggested, but I think ill daily the truck in my current tune, no smoke and it runs good!
