Not only do I never drive below 2500rpm, I definitely didn't dyno that low... This is afterall a DOHC engine.
Dyno graphs starts around 2600rpm with a pretty flatline 168 until IMRC (3300-3500 range) Then of course it drops noticeable (down to 150ish) Climbs to 160 by 4800rpm and stays above 160 until about 6000rpm) Then slowly drops off until stock 7000rpm redline. Not too shabby at all for a small DOHC engine IMO... Have to love the SVT cam profiles.
HP hits 150 at 4900rpm, 160 at 5200rpm, 170 at 5550rpm, 180 at 5950, 185 at 6500 and flutters until redline (all above 185 - either too much advance or too little fuel or too small upper intake???)
With a higher redline the HP will just remain flat until about 8k according to the computer models. Not that you would take it that high (safely anyway)
Sure it's DOHC, but it never hurts to have a good low end to get the mass moving. I know dyno graphs don't usually start that low, I was just curious. I'm glad you never drive below 2500, but I'm not always on a racetrack, sometimes I just end up below that on account of traffic, and I like to have some oomph to get moving because I'm too lazy to shift to a lower gear. You know, some engines CAN safely go to 8000 (or 8500 for that matter
). Not that it would be worth it to rev that high. With stock cams power is pretty much done by 7500.
