Sodium filled valves

Sort of off topic, but someone was flow testing the new head and they said it needs a lot of work. I didn’t get specific numbers but seems that the headifold is limiting (to nobody’s surprise).

I'm waiting to see what Dr. Papadakis says

You can see from their teardown video it is flowing very similarly (within a few CFM) to a stock 2JZGTE head (exhaust side)

it won't have any trouble pushing 1k+ then

Nope, heat management will be the big one.... Keen to see how it goes!

Quote from Headgame Motorworks who has flow benched the Supra head:

HA! no flow numbers shared.

But will say it's the worst cylinder head in terms of flow ever on the flow bench.

The one redeeming thing I can think of is that we always have the other B58 head to turn to if that becomes necessary for high horsepower.

EDIT: Here is the flow from the test, also Stephen said in some comment that the flow was OK, not great.

Those numbers are a little less than a stock 2J, but theyre close enough.


Intake/exhaust:

.100" 81 65

.200" 155 122

.300" 199 145

.400" 207 151

.500" 215 152

Correct me if I'm wrong, but flow testing only tests the valves? Not really the actual port? Because the issue with this head is you have 12 valves all bleeding into 2 small-ish holes.
