Flow testing the Wonder ported head!! 

Uncle Johnny's dancing is second to none.

Before I watch this, I want to thank those responsible for me spitting out my freshly poured IPA after reading the video description. Stevie Wonder for the win!

Love this work. Thanks for the info. Love from New Zealand as always :D

I'd like to see some more commentary on how this head flows. Looks like all gains on the exhaust side and only a little loss at low lift on the intake side, could a good valve job or back cut help the low lift flow? Also how would the turbulence at 0.350" effect how it runs. Is there a loss in port energy and air velocity that could hurt low rpm power and drivability or will this head perform better than stock but not as good as it could be?

Hi Dave, while you don't upload new video, I'm reviewing the old ones. And when I watched this video, a doubt arose in me, the noise that occurs in the intake, that humming noise that you show at minute 3:56, is it when it starts to be turbulent and you lose air flow? Is it due to excessive speed of the air in the port. Thank you. All the best Goyo

The flow of all gasses in combustion engines is wildly turbulent

Love it.😁

I still have the spare Subaru L25 heads if you wanted to check them out or do video. Everything is OK with the car itself. I got them because I thought I was going to have to use them in a head gasket job. Turns out everything is ok. I'm in NJ as well, they said a dealer did work on it, from milling to 3-angle grind with being vacuum tested etc... just putting it out there They say, from listing: "These heads have been reconditioned and were sold threw a Subaru Dealer in Denver CO ,I purchased the inventory of a now out of business repair shop and these were among the parts. I contacted the dealer and they were able to give me a basic description of what gets done to the heads. Cam seals included, installer must set valve lash and put sealant under rocker plate. hot tank cleaned and inspected, pressure tested deck resurfaced new stems, guides, valves, and seals milled to .0015" for straightness 3 angle grind of valves and vacuum tested Here are the s/n's on the heads and other markings on each head for reference only and does not effect compatibility #1 584500 AS 004 7-1B #2 980518 Q1 013 6B I am not the original purchaser so I have no way to warrant the items, sold as-is please be sure to inspect pictures as these are non returnable, I think these are non egr heads but not completely sure "

Question : do you fill up with welding bowls that have irregularities and exceed the ratio between the bowl and valve?

I can't tell you how many people I have met who think a Huge cam and porting a head as big as they can and a half ass or "lapped" valves wlll make power.... Which it won't. I learned a lot from bret but I will still never be as good as him and you. Great stuff buddy! I wouldlove for you to do a Video on my Vortec 4.3 heads that i ported if you're interested tell me what I did good, what I did bad and what i could improve on.

If you don’t mind me asking we’re did you get the valve fixture from that opens both valves?

It may not be as important with turbo/supercharged applications, but for N/A applications port velocity is every bit as important as volume (CFM). I guarantee that Stevie Wonder killed the port velocity and other flow characteristics that you don't see in the CFM numbers. I've enjoyed your videos, this is very interesting stuff even though my background is domestic performance.

DAVE VS UNK ‼️‼️‼️

"STUPID IS AS STUPID DOES"😢

Uncle Johnny is hard to deal with haha.

@headgames is there a way I can send you pictures of a 2jz ge port i want your opinion on it before I install it

That was funny

The air goes turbulent? That doesn't make any sense. The air you exhale with every breath is wildly turbulent.
