We have been down this road with you before, and if you refuse to educate yourself, don't miseducate others, thats just irresponsible. Its almost as bad as telling people the Compression ratio, which is volume based, can be used to linearly calculate pressure. Again, not a 1 to 1 comparison.

So, you think GM does stuff willy nilly, but Ford not taking action proves something? I dont buy that, and I dont think every company has the same level of expertise and R&D for all the platforms. GM makes some crappy engines and Ford makes some great ones, and then Ford makes some bad choices...

It seems you dont understand chemistry. Volume is a physical size of something, not a quantity as it is used in some cases. And you arent even increasing mass flow over another turbo, unless you get the IATs lower. Big difference between mass flow and volume flow. You cannot control boost...

turbonator, what turbos did you use on the center mounts you built?

I dont think the piston needs to change just to use a wider flame front, and I am basically saying I dont think velocity is the key to great mixture in the cylinder. I would prefer great dispersion, distributed pressure across the piston rather than hoping the swirl thing works at elevated fuel...

Oh believe you me, the pump mapping and timing advance was tweaked every which way, and this would easily work on normal 6.5 turbo engine out to 100cc. When I run loaded I get no haze at all, and I usually think of any haze as some inefficiency in the combustion. Might be surprised what a...

And why wouldnt you want the flame to be a little wider on the piston, the more area that you apply a pressure the greater the force it exerts. And the wider it is, it may mix with oxygen in the cylinder quicker, faster exposure.

To me, the 10-blade turbine is recommended, but seems the sellers have no idea they even exist, and won't ask suppliers to provide it. Its just random. Seems most original purchasers got the 10-blade and now everyone gets 12-blade. The 12-blade should spool a tad faster, but the 10-blade...

Yes, MASS AIR FLOW, that is more mass, people just incorrectly apply the theories to volume (CFM is a volume flow). And its not voodoo that a larger turbo automatically means better mass flow. To increase mass air flow you need to increase boost or lower the air temp. If you do not lower the...

The squish area plus precup makes up the entire combustion chamber that is the 1 factor in the XX:1 compression ratio. So any change to the precup volume lowers the CR, which will lower cylinder temps as well. It could also be done to help burn more fuel volume, more precombustion. On...

I wouldnt say we have no experience, that is a generalization. I have been monitoring power impressions, how the larger turbos feel with different engine configs, some precup experiments that have been done already, and another 6.2 precup engine that wont run 70cc without black smoke and high...

Yeah, I commonly adjust the height or width of the opening on the spade receptacle until its a tight fit to whatever thickness terminal youre putting it on.

Very Cool. Nice wastegate plumbing. Is that 2 CDRs as well?

Youre talking about AIR MASS, you passed more mass :hihi:, not volume through the engine. An intercooler is rated for CFM, do you ever find one rated for the same high CFM as the turbo? No, because it goes off the CFM of the engine, it doesnt care that you took 2 cubic feet of air and made it...

And what you dont see in the pic is the back side, the inner volumes got greater, to drop the CR over the years.

Thats not true. Go do the math or physics/chemistry. Its a physical fact. The engine is a fixed pump, it only flows 6.5L of VOLUME per 2 revolutions. At the same temperature that 6.5L is the same mass. When the temperature is lower, there is more mass at the same CFM through the engine...

People do it all the time, when they swap engines or heads and use the latest precups GM made. Compared to the smaller, with smaller mouths made in previous years. And GM continually increased the power rating, so it seems they already did it for us. I am not contending that 6.5ers have to...

Not everyone runs only 80cc of fuel, I can hit 100cc or better with a stock DS4. Highly modded DB2s that can push a bit more. That doesnt mean every precup is even able to handle 80cc very well with a specific CR, boost level and Air to Fuel ratio. Your conclusions are drawn by inference...

Dylly was correct, the CFM is exactly the same through the engine at the same boost level. The mass flow is exactly the same at the same IAT. But because it is more efficient there are gains with larger turbos with lower IATs. The definition of efficiency is basically how much mass are you...

Simply put, just because you are not wrong, does not mean you are right. You might be right about one thing, and completely missing another point. You can't speak in terms of facts until you have proven yourself right, and thus far you have not. You have simply taken a specific configuration...
