Agreed, I forgot to include the new HP standards to the old standards, and why the 306hp rating of the HR is not exactly 6hp more than a REVUP.
With that being said, I still wish they would bump the displacement above 3.7 so that more power could be gained. I like the thought of a 400Z.
But that's wishful thinking.

Based on this I would definitely expect more than 320 - 330 crank from a 3.7L in the future.
We can only hope!

the 2006 is a "collectors item" in my mind because it was the only year of full-on Revv-ups... The HR could be in the same boat.. If 3.7 comes out in 2008, that would be 4 different engines over 4 model years...Interesting times indeed.

The 243whp was a modded REVUP on Sharif's dyno at Forged Performance.
He dynoed a stock HR and got 245hp.....
Since there are not really any mods for the HR engine he went towards the exhaust and proceeded to fit a Greddy EVOTT exhaust and modified TPs and re-dyno the HR to get 263rwhp (Without rechecking the thread I'm pretty sure it was a gain of 18rwhp.... Sharif said he was surprised). These gains were seen without any tuning, just bolt on.
Forgive me if I've misquoted any info from the Forged Performance thread. I believe the thread is listed under the engine modification section.

Now factor in how much fewer rev-up and HR engines there are compared to the original DE, and the future seems a little bleak for them. With the VHR coming out, the HR guys are already driving old engines, and with maybe just one year in production, I don't foresee a lot of options or them as compared to the DE or VHR engines. At least not as soon as what came out for the DE, or what will probably be coming out for the VHR once the GT-R is here.

Now if we can get the 370Z with the same motor making 345hp 290tq.. mmmmmm
