I am very comfortable with the OP's assertions because I know who he is and what he does.
I can also understand why many would question the OP's claims.
This site has its hierarchy of expertese and someone who does not post often is naturally going to be questioned. It's the nature of any board.
So lets just do the mod and do the before and after dyno's. We will do it at Team ZaG's shop and have it dyno'ed at V2.
Who do I get to knock out once its done?

being skeptical is great, but being a dick about is not. being skeptical does not mean you do not believe it, just that you need more evidence, information, proof... whatever! asking questions, or allowing the author time to explain is the proper way to get a resolution and get to the truth.
do you get what I am trying to say?

Really, that shiet is annoying.

I would just like to point out that the people who are complaining about the the way the other members are acting towards the OP are the reason people are still doing it. If you just stop trying to get in the last word, then the next person will not have anything left to say. You are fueling the fire and complaining that this thread has gone to waste but it is because you continue to bring up the useless posts saying things like "BS" or "PROOF" so just dont mention them and move on. Maybe we can redirect the focus back towards the original discussion.
So, with that said, does anyone think it would be possible to use HR cams in the non-revup, or maybe since the revup uses that VVL or w/e it is called on both intake and exhaust, then maybe it is possible for you rev-up guys to save a buck and use HR cams instead of buying aftermarket for $1000. If you gain about 10HP then thats a decent mod because you are getting about the same as you would from lets say, JWT cams, for a fraction of the price.
Please discuss, and lets act like a FORUM, and try to make some good out of this. Maybe some peoples goals of NA power can now be achieved w/o having to spend as much money.

Case closed.

I don't see how this is a cost effective mod.

Area under the curve could also be a big selling point. We won't know until someone does a clear before and after dyno.
Case reopened, pending dyno.

It's a well known fact that the plenums differ on the HR's and the 287's. It would be very remiss (read: STUPID) of you to ignore this fact when trying to get your precious "HR" power, dumbass.
What proof do I have? Nissan's claimed crank hp and tq numbers. Doesn't get better than that, son.

Well the lift and duration of the 287 vs REVUP cams aren't too different I would think. The main gains are coming from the timing adjustment by moving the exhaust sprockets, but then again that will throw off many other aspects like smoothness.
If someone is going to do cams, you might as well buy the ones that have the higher lift that have been proven like JWT, tomei, jun, etc. I'm not saying the REVUP exhaust cam isn't giving power, i'm saying there is more power with much more area under the curve with both intake and exhaust cams that are aftermarket with a higher lift and duration.
If the REVUP cams were that great don't you think crawford would have used it on their Z instead of using their own custom ground cams?
Not trying to be an ***, i'm just being logical thats all.

Thats a good point. But what i would say to your crawford comment is that yes more power can come from a much more aggressive cam, and in the crawford car they had the money, and ability to make whatever they wanted to go into that car. Also, to aggressive is obviously not streetable for several reasons. With the saving some money issue, possibly getting the Rev-up Ex cams, and then getting some tomei or Jun, GT motorsports or w/e intake cams could be quite the power adder. If just this exhaust cam upgrade is yielding about 10HP, then getting some aftermarket intake cams could definitely do some help also. And since the Rev-up cam mod apparently makes about as much as aftermarket intake and exhaust cams do, coupling the rev-ups w/ some Tomei intake cams i think you will have a pretty potent combination.
Also, for my personal knowledge only, do they make any aftermarket cams for the REV-UP engine?
