"I GOT HEADS! I GOT HEADS" Taking a closer look, we really did get NISMO 46cc heads!
Good thing there is 93 and 100 octane around the corner.

Now here comes all the questions about the upcoming configuration changes on jeffs car.
I had already mentioned this to Jeff over at the shop, but I thought I'd throw it in here for good measure.
As jeff wants to end up with Turbo, isn't part of the idea about running turbo is lower compression (to a point fellas) allows better gains/performance/safety on turbo operation?

When we do the turbo project will will also build a low compression forged bottom end, with the Nismo heads coupled to it. The pistons will be custom made to end up with an overall compression somewhere between 9 and 9.5. We are still working on the numbers, but it's race season right now so my car takes a back seat for a bit.

and that is universal problem with Dynos....
You never know what you're gonna get, and there isn't too much that can be done about that, unless all the dyno operators, synchronized their "adjustments" and made certain everything about their dyno was A1 condiion and configuration and then if that wasn't enough, they would need to programmed identically.
Of course, next on the list is altitiude, and atmospheric conditions, so who knows... Dynos are guides and generally not fact.
None of the above is going to happen, and as Jason mentioned in a post as well, you will get different results from different dynos.
Have you been to dyno'd your car at various locations at similar times and weather?
275 at the rear wheel doesn't seem likely unless you have an abnormally stronger engine, and all things in the universe were in your favor at the time.
I'm not putting you down/ragging , it just doesn't seem likely.
if you do have 275, WOW!

That is what I find unlikely, not that your combination of mods can't produce 270....
Of course if there is something that he failed to mention as to what "half" mods he has like (no exhaust, straight exhaust manifold) along with cams/pulleys/intake perhaps it's possible.
But then again, what do I know? (don't answer that)

The dyno is relative to itself.....that's it.
So what good are they? Simple - for comparing results among other cars that dyno on that particular dyno. Let's say a 911 TT with the X50 package dynoes at 400 at the wheels on a local AWD dyno. I bring my Z in, and it dyno's 260. We know that the 911 is making substantially more HP than my Z is. Is it really 140 hp more? Noone can know that answer for sure, but it certainly is fair to say and logical to conclude that the Porsche is making substantially more HP.
Now the other extreme - one guy in CA dynoes his car with a set number of mods at 260 hp, and someone in NY dynoes their Z with the same exact mods and 250 hp. I would bet dollars to donuts that if the two cars were ever to lineup side by side, they would be near neck and neck with each other.
Use the dyno for what it is guys - an estimation and a diagnostic tool. It is not the empirical be all and end all in HP.

That is a fantastic article. I'll keep that link saved for future reference.
