Some impressive numbers but not really all that impressed with the Roush and Whipple, I thought they were putting out more. From what I am seeing, I won't have to worry about the 425hp mark with the Roush and a 2# lower.
They are SAE, but as you can see from the straight line on both HP curves, I couldnt get traction on the rollers. With the blown motor it spun the tires all the way up to 3500rpm. Next time Im goin to run my slicks to try and get traction.
The dyno is a DynoMite from Land-&-Sea that I have pretty much unlimited free access to. The numbers seemed a little low to me too, but Im not sure. If nothing else it shows the improvement over the old engine.
HI!... I never had a chance to dyno my truck when it was stock, but I've seen two dyno stock. One made 195RWH.P and the other made 189RWH.P. Both were stock 5.4's.
i guess u never been to a dyno day with more than 200 car show up. an to tell the truth i really dont care. hot lapping is a true test of your machine.
