The owner will get all the dyno results, of course. I have 3 dynes here, 2 engine dynes, and a chassis dyno. I will have 3 different sets of plots from this car, since I repaired the engine thats currently in the car last year (nothing wrong with it today).

I have learned over the years that anything that we post publicly ends up getting used against us. This is why we don't post graphs, under any circumstance.

I can't wait to hear how this turns out. Will the redline be increased on this engine or left as stock?
No, not in this iteration of the combination. The stock hydraulic lifters are not even effective for the stock redline, so we work to make more average power and to DECREASE the point where peak power is made, away from redline. Typically when I perform ECU tunes we turn the rev limiter down, not up, because the extra RPM isn't necessary, and it creates extra friction, extra heat, and kills lifters and valve springs.

No, "tuners" won't tell you this, because they aren't internists and they have no comprehension of the mechanical limitations of these engines. We love them, they blow up lots of lifters and keep our schedule filled with the fruits of their labors.

In a few months this engine will see my L3 cams and even higher performance valve springs, along with my modified tensioners. At that point we may decide to increase the rev limit a few hundred RPM beyond stock. If so, it'll also get my higher performance lifter package.

The car has been dropped off at the shop as of a few minutes ago. The engine is being moved from my clean room at the Research Facility to the main shop on Monday, and the transformation of the vehicle will begin.

Here's how the engine stands right now...
