80s tech is even a stretch....

 

why isn't a t25 as good as an EFR6258?

 

Why isn't one horse as strong as hundreds of them?

 

Obviously you guys havent tried the tornado on your n/a builds. This was engineered in a wind tunnel! Reap the rewards of whirling air no matter how small your ports.

 

When I worked at Autozone many moons ago we sold those LMAO.

 

Why isn't donkey as stronk as ox?

 

Bad port design and low static compression.

 

Ehh...

...exactly. The size of the port is not actually of all that much consequence. Bigger ports mean less velocity, which means less low-end torque, even if the flow numbers are the same. The port design is what those photos are showing. The BP's short side radius is laughable. When a pro ports a BP head, they can't even touch the ceiling of the port, because literally all they can do is make it worse. The B16 port looks like a factory race head, just like all of Honda's heads do.

 

Because every car performs better with an inlet restriction!

 

What part of vortex dont you understand? Jeez

 

who wants their air STRAIGHT anyway?

 

Right

 

GAY air has more fun!

 

My initial impression after pulling a silicone casting of the intake port was the opposite: leave the floor and work the ceiling.
Have somewhere you can point me to talking more about this?

 

Port a head and stick it on a Dyno. That's what Andrew, myself and a few others have done for the last decade or so. Bowl blending doesn't mean port shaping in my view. That's just correcting for low cost manufacturing processes. Filling in the short side radius time-tested approach to low port angle heads. In another life, we did that to 2.0L Pinto heads.

 

it's 2018. We need to let the air choose it's orientation.

 

Google "short side radius"

unnatural aspirations

 

I took a casting of a VVT head and then laser scanned the casting. Here it is: https://a360.co/2JKtHkp
Rounding out the flat roof from the injector pocket through to the bowl looks to me like one way to achieve the appropriate change in cross section through the length of the port.

Even with filling the floor as an option I didn't see the shape up top as being good. It doesn't look like it has an appropriate change in cross section through the length of the port.

 

Just to make some things crystal clear here.. The port roof is where the guide protrudes out of, and the floor is where the short turn radius is.

Id never touch the floor with a carbide cutter because the short turn is so bad
