Just got news...ETP 225 flow numbers...added full flow numbers... Intake:
.200 138.30
.300 214.30
.400 266.40
.500 302.54
.600 320.76
.625 327.09
.650 306.50
Exhaust
.200 110.21
.300 160.68
.400 206.36
.500 222.37
.600 231.00
.700 236.54
We've flowed alot of LS1 heads on this fixture and this head outflows any ported stock casting tested on this bench by 20+ cfm. Never flowed my old GTPs on this bench, but I did have them on a SF600 and they flowed 294 IIRC
Flowed on a 4.00" bore @ 28"

Was any wet flow testing done?
People talk about velocity and the like, but again you guys are still stuck in the world of dry flow bench numbers. The wet flow bench test at .55 inches not .28 inches. When you add liquid to the air the density of the air changes this is something you would never see on a dry flow bench. SO to talk velocity on a dry flow bench at .28 inches, who cares. its all for not. You dont have any idea what it will do with fuel, as the density of the air changes, and until you flow the head on a higher level like .55 inches instead of .28 inches you dont see the truth anyways. Bret from Bauer's can back that up as he has tried other heads you guys praise at .45inches on a dry bench and has seen how the heads fall off. That tells you in the real world on a motor that the head wont be as good as it looks. Sure it will probably make enough power to keep you happy. But lets say you take a head that flow less at .28 inches but flows better on the wet flow bench or even the dry flow bench at .45 or .55 inches of water, what do you think will happen? The engine will make more power!!!! Thats a FACT, so keep looking at those great numbers everybody post, but until the "industry" standards change people will keep asking for stuff that doesnt really matter, or that they dont really understand why it does what it does!! Heck the guys writing the magazine articles dont know, thats why they write articles!!

I had a set done like 3 months ago and have another set (215's) at the shop to get done right now.
My numbers weren't as good as your but I use a JMK bench and the numbers are about 5-10% lower.
However the 225's did out flow all the stock ported heads I have ever had flowed by a good bit.
The stage 3 TEA's were close in the peak numbers but that is really the only head that was even close and it was 8cfm's less at 600 and more then that from 200-500

I don't think people really use the wet flow benches for numbers, but more so to examine how the fuel separates or does not separate from the air stream. Good luck with those heads Brian!

Is the .650" measurement a type-o? Seems like they wouldn't go static that fast but I guess you never know. Go hit the track now man and get us some results.

The 225 numbers look good Brian. Very similar to the 240cc ETP heads that Tony Mamo flowed:
Intake
Head Int. Valvelift ..........Runner
.. .200 .300 .400 .500 .550 .600 .Volume Comm ents .
"Z"....137...211...270....310....324....336.....24 0 cc's ..New "Best" peak #'s
Exhaust (with pipe)
Head .Exhaust Valvelift ..Runner
...200 .300 .400 .500 .600............Volume
"Z"....117....170...215...241...253........... .95 cc's.....BIG port / strong #'s

Here are my ETP 225's that were flowed on Force Fed High Performance's bench. Did you have a pipe on the exhaust? The intake is very close until .650
