Someone said it's on an engine dyno. Can that be confirmed or not?

Still some very easy questions that need some simple answers.

if it's an engine dyno, this would also mean that the whp gain is lower...

That is a dynapack, with a correction factor applied. Read the plot again and view the right side column. You will notice axle power. Dynapack attaches tot he hub and is not a roller based dyno. It is fairly common for people to apply correction factors. This is not an engine dyno.

Regardless of what the gain is you are seeing a peak of ~ 9.7% gain at the largest gap @ 6359. So if you were on a Brand X dyno making 150WHP @ 6359HP and these gains were consistent then at 6359 you could expect ~ 164 WHP. This mod is essentially shortening the power band but increasing it at the same time. Luckily it is not shortening it by very much, it looks like they probably played with height until the falloff lined up with the factory one. However your "butt dyno" will feel like the car has a significant power loss at higher RPM due to the fact your get a negative surge for a longer period of time even though you have nearly the same HP at redline. This is why I purchased these I an extremely curious how cam profile adjustments will affect this and if the gains I can currently get at 6800 can be still somewhat available if so this could give very nice mid power gains, but I won't know for about a week or two

I have not received the package yet. If they shipped it out Friday it will probably show up tomorrow.

So I plan on getting a full blown turbo kit. If these power blocks do end up making decent power, would the turbo kit fit since the power blocks raise the manifold

So when you do get it.... I'll be expecting pictures for the package/install looking just like your teardown pictures.

How reliable are spacers like this? Will this cause any premature wear and tear on anything?

I don't see how it would. Its somewhat similar to throttle body spacers that increase the volume of the intake manifold.

Even if made of right material I bet the gains FI are not worth the cost or trouble
