Saw the 5.2 on an engine dyno

[ohtobbad]

I seen plenty of engines on a dyno.
Seeing 5.2FPC would be cool, but without knowing more.
IE: some numbers, its meaningless, we all know its seen plenty of dyno time.

Was this engine dyno held at ford?

No. Independent race shop.
One of the teams that does development work for Ford.

I agree.

Cant wait for all the info to come out.

10,000 rpm's........the magic of overhead cams! Try that with pushrods...........

I love my Boss for this reason. It's so rev happy. Much different than my old 392.

Its even better...

As I said in my original post: way past 10k

NASCAR engines can hit over 10,000 RPM... But I guess if you want to talk about racing engines you could show a DOHC F1 engine hitting like 20,000 RPM.

Was it still making power at that point or was it dropping off pretty hard?

Those NASCAR motors cost more than the GT350R.....F1 cost more than a new 4 bedroom house with a two car garage.

But a race engine is a completely different animal than a production car engine. Those NASCAR engines might last a few thousand miles at the most. They are tired after 500 miles and it's not uncommon for a NASCAR engine to not make it through a 500 mile race.

Completely apples and oranges when you compare a NASCAR engine to something that is built to last over 100,000 miles.

How long till electric solenoid actuated valves? That's good for alteast another 2-3000 rpm. New koenigsegg is running pneumatics.

It made power all the way to the rev limiter.
No dips in the curve, nothing.

Very impressive as I said before.

In CA?

No, in Michigan.

So what you're saying is when they are dynoed in owners hand, they will pull right past the 8250rpm redline and continue to make power whereas most cars peak a few hundred rpm before redline? That's one hell of an intake manifold and some pretty large cams to do that.

Assuming 360 lb/ft @ 9500 rpm, 650 hp? Interesting
