300 hp slant w/turbo... suggestion
If you build properly, you don't need much boost... (Shhhh! Don't tell anyone though, they think it's better to build a poor engine and the pressurize it to death, because 'boost makes up for it' and then think 300hp from 23psi is wonderful)
"Poor engine" denotes an engine that breathes poorly. A well-built engine will have a professionally ported cylinder head that flows as much air is possible BEFORE the turbo goes on, making possible
high-output, at a relatively low boost.
There's an old saying; speed costs money... how fast do you want to go?
In this case, I proposed a 300 hp slant six without even an intercooler, to keep costs down. The crux of the post was to get as much for your money as possible, aiming at 300 hp, the whole time. Forged pistons and rods fly in the face of that line of thinking, because they are not cheap. But, in the interest of long-term reliability, I swallowed hard, and recommended them because I thought they'd be worth it, on several different levels.
A first-class, ported head is going for around $1,200.00 to $1,500.00 from what I hear, these days.
You cannot achieve the kind of results you posted from a "good" engine without one; the stock head sux in the breathing department. BIG TIME!
Since the whole rationale of my post was that it might be able to build a 300hp motor for an amount of money that would not be so damaging to one's budget that it would prevent the whole project, I tried to minimize expenditures where I could.
I admitted in the article, that a ported head would, indeed, be faster, but declined to suggest it in the interest of economy.
With a forged piston/rod/crank motor, I figured the desired 300 hp would be attainable by cranking up the boost a few pounds, rather than dropping $$$$$$$ for a ported head.
Is there something wrong with that logic?
You seemed to think it was not a very good idea.
Tell me why, please. I don't think the boost will have to go over 20 pounds...
