340 improvements with dyno numbers

you realize that is a magazine article.
I do. That is a problem somehow? The link is attributed to the owner.

Build it and be disappointed when it acts like a 330-340hp engine.

That is intended as a response to something? I don't know what that might be.

It's not a 'build'. It's a stepped process with performance numbers attached to each step. And having ended up with close to 400hp, how does that related to the stated disappointment?

This sure got off the rails quick! The link is simply a list of some common modifications with dyno results. There is no indication of the link having an intent of 'building' a 10-second car...or anything else.

What is all the angst about?
