I tuned a car last week that made 692rwhp on a similar dyno - a dynodynamics thats around 760rwhpo on a dynojet im led to believe. It also had a F1 Procharger and was on a 346 with about a 230 cam, LS1 heads, with Ross Pistons and shorter scat rods. This power was made through an auto with a PY3400e converter. The boost at fuill power was about 18psi. WEe also made the power on MS109.
These F1s certainly do the job and its boosts usefully at 2000rpm as well.

6200rpm peak on the power band. Id imagine if he drag raced it and hooked, he would need a lower gear or higher limiter.

I didnt notice what gear he had, but my 347 peaked around 65-6600 with the same cam/blower and didnt really drop off quick. My car ran best shifting right at 69-7000 and still pulled to 7300 through the traps just fine, even though looking at my dyno numbers you would think it would not have pulled past 7000 in high gear.

As long as the average power is higher shifting up at more rpm then its not as bad as it may appear. My car stays between 6300 and 7000 most of the way down the track and I would bet the average power is greater between 6300 and 7000 then it is between say 6000 and 6700 since the car runs better shifting higher. I'll have to average those dyno/rpm range numbers one day..
