Are these predicted hp numbers even remotely correct?

I found this on the nasioc turbo forum: TD05-16G (small) - 505CFM at 14.7psi for a 2.0L engine . . . click on the link.

On the turbo chart it also gives a set of conversions to approximate hp:
1 HP approx equals 1.45 CFM
1 CFM approx equals 0.0745 lb of air/min
0.108 Lb/min approx equals 1 hp
1 Meter cubed/sec = 35.314 CFS = 2118.867 CFM
1 KG/sec = 132 lbs/min approx equals 1771.812 CFM

Now if I do the conversion:
505x0.0745=37.6225lb of air/min
37.6225/0.108=348.356hp

Now I'm assuming there are other factors that take away from this number, and I know that this is ESTIMATED crank hp, not wheel hp. However, the measurements of CFM for the TD05-16G are based on a 2.0L engine and not a 2.2L engine. How would these measurements differ with a larger engine?

Now close to 350hp would be nice, but I'm not really thinking that's the case with my car. Especially since I'm maxxing out the injectors . . .

Anyone care to comment?

the extra 0.2L shouldn't change much considering the 2.0L engine is a bit more efficient. Better ECU and better flowing heads. So I'd expect the peak Hp to be roughly the same. Torque may be different, but thats a whole different realm. I do see the TD05-16G making 350 hp though. At something more realistic like 20 pounds with proper fuel regulation and some upgraded engine managment. These engines have alot in them but you have to spend a sh*tload in support systems.

the fact is, that is not the amount of HP you would make, but rather it is the max hp you could make from that turbo. i have heard from other sources as well that about 350 crank hp is the maxxing out the td05-16g turbo. :o
