W series heads are NOT legal in Stock or Super Stock. Just an FYI.
Not in Stock but in certain classes of Super Stock they are.

in terms of power made vs effort the TF's are hard to beat from what I have seen. However in terms of their ability to make real impressive power I'm not so sure
There are classes where the W2 head is legal in Super Stock.....like SS/BM or CM....but correct on the traditional SS classes no...
I’ve made in the 580’s with ported RPM heads and an easy on parts roller cam.
You def couldn’t duplicate that level of performance with another set of RPM’s for what you could buy the TF’s for.
So, if the TF’s were exactly as good as that set of ported RPM’s, and made the exact same power........ it would be equal performance for less $$$.
Plus...... you can buy them set up with a 2” installed height and roller springs to accommodate a .700 lift cam.
Oh and those didn't make a jawdropping amount of HP either.
I agree with you Dwayne, I'd love to do that.You weren’t really expecting them to after looking them over and flowing them though.
And..... the TF’s are less $$$.
Here the test....... two sets of heads.
The TF’s right ootb....... do nothing but bolt them on.
The other set, some RPMs that you buy new, and upgrade only as much as you can, and have them not cost anymore(customer price) than what the TF’s cost.
Dyno both on the same 550hp plus capable short block/induction/valvetrain.
See how they stack up in the bang for the buck category.
I agree with you Dwayne, I'd love to do that.
I betcha they wind up DARN close like less than 10 HP/Lb/ft close.
A customer walks in and says I
want a 500+ HP 408 and aluminum heads. I'm not gonna instantly sell them a 408 with TF's. I'm gonna sell him a truly CUSTOMIZED (investing myself-cuz I'm passionate about this stuff) engine with heads that are the best VALUE and will also meet their expectations. The upshot is substantial --meaning TF's are not even close in price to SM's or Eddy's -so I can work and earn $$$$ to meet the HP goal that a TF would provide.
In short if I can make an Eddy work as well as a TF and make some $ doing it then as long as I'm not rushed or lazy I will take that route. Or if the customer specifies the TF's I would use them I should add.
From what I have seen the TF's even with their gorgeous chambers and gorgeous CNC work and wicked flow rates should make A LOT more power than what is being reported.
We should start yet another thread about cylinder head flow rates and why a 265 cfm head makes more power than a 300+ cfm head. I've witnessed it many many times. I am getting a good on handle on what REALLY makes power. The other side of the HP coin is --HOW hard does it accelerate? I have been in high HP rides that didn't accelerate nearly as hard as a 500 HP package. J.Rob
Your last paragraph needs to be read. And read. And re-read over and over and over and over. You can't read it too many times.
That's one issue the water brake dyno has. It doesn't measure the ability to accelerate. Doesn't mean it isn't an a tool you shouldn't use every time. Like a flow bench, you need to understand what the tools limit is.
Read that last paragraph over and over. RAMM nailed it.

The problem with the dyno is that IT dictates how the RPM's are accelerated. The inertia based dyno that the Carb builder shootout at BLP was held on is probably thee BEST to figure this stuff out on. I think most dynos do a good job but unscrupulous operators are the biggest chink in their armour. J.Rlob
No need, I have it. It has a special dial to adjust the tail wind.We should start a Dyno post to see who has the fastest DYNO. Lol
And I could derail it!......lol...We should start yet another thread about cylinder head flow rates and why a 265 cfm head makes more power than a 300+ cfm head. I've witnessed it many many times.

I would enjoy that kind of thread vary much

my opinion is that there is very little difference from an out of the box trick flow and solidly worked Eddie regards ET/ mph. I frankly expected to see a notable difference... say maybe pushing 3 tenths type stuff, but i am relatively positive there is nowhere near that kind of difference.
AKA - Best bang for the buck in there type of head and performance arena?I don’t know why there would be such an expectation from the TF heads.
They aren’t any bigger, and don’t flow any more than the MCH type of CNC job on the RPM heads.
Imo, the biggest benefit to the TF head is what you get for the $$$$, and that they are available with 2” installed height springs.

We should build an engine and ship it to a half a dozen different dynos around the country and see the results, they did the same thing with flow benches and a cylinder head at one time....We should start a Dyno post to see who has the fastest DYNO. Lol
