Well.....
With specific output, I was refering to the SVT 2.5...200 HP/2.5L = specific out of 80 HP/L. SHO is 220 HP/3L or 73 HP/L.
As far as revs..I think the engine may be OK at these revs with the DMD. without = not a good idea, though SEVERAL SVTs have chips with 7500 redlines that visit frequently without apparent problems thusfar. Talking to Al Mirko and Chris Reinke ..both SVT Touring car drivers, the stock valvetrain (which they used except for 3L valves)is good for around 7800-8000 RPM before float is an issue. Duratec cams are lightweight hollow parts, valve stems are slender stainless steel and roller finger followers all reduce valvetrain mass. The new BMW M3 uses all of these to get 8000RPM. Even higher revs, direct acting buckets better from what I gather. I think biggest problem for Duratec at <8000 RPM is probably crank whip..hense the DMD recommendation. Also, oiling may be iffy so an extra 1/2 quart in the sump and possibly Accusump desireable especially over 7500 revs.
Note that modded SVTs can actually benifit from 7400 RPM in contrast to most cars. Peak power for me is 6900-7000, right at fuel cut, and dynos on other chipped cars suggest that power falls of slowly until 7400 RPM or so with stock SVT cams. So basically, car will pull hard until 7400 RPM and improve power area under the curve.
