Cams in general are more of moving the powerband around.

great genral knowlage... now how does it apply?
what does the NA cams do for the turbo engine?
lower the power band so you have more lower end 'grunt'?

From what I have research, na cams in your 7m-gte are good for a few ft/lbs and even some horse power, but they wont withstand the abuse if you are running alot of boost or are aiming to hit high numbers, ie. over 300-350 horse. So if you are pretty much stock, then you will probably notice a nice increase, if you are looking for a reliable high horse power build stay away. Also make sure the cams are in good shape or you might risk jacking your valves as well as you guides, that could get pricey...

Cams dont add air, or fuel, so please tell how you are going gain few a ft/lbs or HP?.They adjust as to the amount of air and fuel to allow the power to be increased within the powerband, but with that lost in another area of that same exact powerband.

Basically in Lamens terms: Turbo cams allow more top end power, NA cams are more for the Low end to make up for not having a turbo.....Now with that in mind, you take the Intake cam from the NA that is the going to make the powerband in the lower RPMS, and put that in the Turbo.

What is your result?
You are sacrificing some of the Top end power that you had originally from the turbo intake cam but you will get the difference of the NA cam to come into play in the Lower RPMs of the powerband.

When the vavles stay open longer they should let more fuel/air in causing a greater explosion creating more hp/toruqe

Why wouldnt they? There not forged or anything like that, there made out of the same exact thing as the turbo cams.

But if i was going to replace my cams, i would do it with some racing cams instead of the na cams, Like from here http://www.suprastore.com/brcr7mca.html
Probly alot better then the na cams.

do tell how turbo lag adds low end power!!!!



Low end power is usually accomplished by higher compression…



The reason turbo engines have little to no lower end is because they are specifically made to keep compression low so you do not get pinging (pre-mature cylinder gas detonation).

You answered your own question. I wasnt trying to go into detail as to how an engine works with or without a turbo. I was merely stating the biggest difference between the two 7m's for general clarification as to why there is such the power difference.

Yay!! you understand that having different amounts of compression will result in how an engine will react.

If you can show me how I said Turbo Lag will result in low end power send me a pm otherwise stop being a troll, I was stating information for the cams and you come at me about compression and turbo's.

Thank you very much this is exactly what I was looking for.
It makes sence that the 7mgte and 7mge cams wont hold up to the abuse that an after market cam built specifically for race applacations would.

I was just looking for some thing cheap and easy I could bolt in while doing my head gasket and this looks like just the thing...


Now that the question has been answered, and there is some totaly mindless off-topic banter that adds nothing to the topic....

Well obviously if you would have said what you meant in the first place, instead of trying to be a condescending asshole (I quoted the original post) you wouldn’t have had to edit your post to clarify your position.
