Wow, I take a few days off......
Wasn't the original scope of the question about bumping up a slanty to stock 360 V8 levels or something like that? I like the side track about spooling a /6, but it looks like you are building up the little motor to get to the mild performance level of a stock V8. In the endgame, you are still limited by the low flow characteristics of the stock slant head. The power adders overcome some of those limitations, but they are still limitations.
Not to be argumentative here, but with up tp 500 horsepower readily available to ther turbo /6 builder, what "limitations" are you referring to?
Side note to the side track:
I would think that there would be more that could be accomplished with the addition of EFI to the turbo'd 6 (with better tunability).[/QUOTE]
My recommendation for a carburetor was based on what has already been done and in a K.I.S.S. mode, a proven line of attack. I'm sure you're right, that EFI would probably offer an improvement in driveability (if not power) over a blow-thru carb, which is usually problematic, at best, IF a good. workable EFI system could be implemented.
Just look at all these vacuum/boost lines/connections to our induction system: grievous complication...:wack:
No argument at all. Just sussing out information.
It's already been stated here about the flow limitations of the slant six head, the lack of aftermarket support and whatnot. I'm not a huge genius on engine building, turbos or blowers. I do know that for performance, flow is key. Using an adder gets more air in (and by virtue, out). Yet, isn't the low flow characteristics of the head still a limiting factor?
It's been explained to me that with a supercharger, the air is heated by being forced thru the intake ports and valves. Yes it's heated initially by being compressed by the supercharger, which is why intercoolers are so effective, but it still gets heated by the restriction in the head. Simply think of blowing across your open hand vs. blowing through your closed fist. Which would you rather do in the winter? Add in charge dillution by residual exhaust that cannot escape thru low flowing exhaust ports fast enough and that is what I consider limitations. It's just physics.
On slantsix.org wasn't there a big thing going about adapting a GM V6 MPFI to the slanty? From what I was reading, it wasn't a big leap. Did it ever pan out?
Still yet again, I ask about a modified smaller engine vs. a more powerful yet stock larger one? Sure up to 500hp is "readily" available with a slanty, yet you still have to pull out the tuning tricks, add in some serious hardware and be at the upper limits of what's available. I'm not knocking the lil 6 popper, I drive one daily, but I also know that my stroked 340 will put the smile on this old mug of mine.
