You could bring up what ifs all day, but the fact is they aren't equal..You can't run 14psi as easy as you can run 14psi in a Cobra, period.
Further more, even if you were able to run that much boost you might be reaching the blower's maximum capability. Once again BOOST is only a measure of restriction, I don't know how else to make you understand it.. A bigger, high compression motor can push the blower twice as hard as a smaller lower compression motor at the same boost level.
As an example, there is a guy on here with a ported eaton, but he has heads/cams and a stroked/built 5.0L. After the heads/cams he was running a 3.1lb upper with a 8lb lower and only making 11psi. If he still had the stock motor he would easily be running 19-20psi+, but he's only making 11psi with the blower being spun to it's absolute limit. It's a perfect example of freeing restriction which then shows a lower boost # on the gauge. Even though it's only showing 11psi he's still at the absolute capability of the blower the same as if it were a stock Cobra was running 17psi+
If I race a Supra running 35psi and I'm making as much power running 20psi in my Cobra, I would be a ridiculous ricer to say "well logically I'll be making more at 35psi". :lol: :bored: For one I don't if my Cobra could handle that boost, and two running "similar FI applications" I could be pushing the application well beyond it's capability REGARDLESS of what number shows up on the boost gauge..
You're too obsessed with boost numbers, read my post above and try to understand how it works. As for bolt-on Cobras making 450rwhp, the blower is FACTORY, (meaning it's designed to pass inspection/smog, be reliable, efficient, etc). "Ifffff I did this and installed this aftermarket blower, and had these heads with this cam and ran this much boost and did this I could make more power." That's all Honda talk right there.
Dude it's not me you should be preaching to about boost and efficiency. I own two grand nationals I know plenty about changes in boost levels when changing things such as a cai, weather, cam, heads, and in some cases headers. You need to actually read the entire thread before jumping in the middle of a conversation and trying to act like you know what all is going on.
I will break it down for you my original comment was "Both lsx motors and modular motors have their pluses and minuses," this is a fact. My next comment was, "When both lsx motors and modular motors are using forced induction then there is no replacement for displacement." And you just proved my point for me. An example is since the ls motor is more efficient 1 lb of boost for a ls motor might increase hp by 25, compared to 1 lb of boost on a modular motor may increase hp by 10 on average. So what does this mean? It means that lb for lb and mod for mod, the more efficient motor that has things such as better flowing heads, cam, and cubic inches is going to respond more favorably than the less efficient motor that has less cubic inches, less efficient heads, cam, and so forth, this is an indisputable fact. There is no if this and that. My car is set up n/a I don't need to speculate what my set up is capable of I already know. I also know what the 03-04 cobra motors are capable of, and could care less if it's set up with a blower or came factory with turbo. The point is my car is making as much all motor as the 03-04 cobra is with a blower; and my car still passes smog inspection and gets 25+ mpg. Now a GT 500 can make 550+ rwhp with just a pully swap, that's something to brag about being pullied and only making 450 rwhp is no big deal in my opinion. If that hurts your feelings well it is what it is.
