this might be a stupid question but here it goes. if you run a gt35r at say 20 psi and then the stock turbo at 20psi does the gt35r make more horsepower or is it the same for both?? i only ask cause i heard sombody say "making gt35r power at 18 psi".

 

You will definitely make more power at 20 psi on a GT35-R, that 20 psi on a stock turbo.The GT35 will produce more power bc of the size of the turbo and way more air flow,but this is like comparing oranges to apples

 

don't fret, this is a common misconnception. MANY people on here don't get it.

I simple terms, 20 psi on the 35r is much different than 20 on the 16g. Reason? Simple... the 35r flows more air. So in a nutshell, it can pack more air into the cylinder at 20 psi than a 16g can. Ovbiously more air = more power

Perhaps someone can plost up flow charts... that's an easy way to read it.

But our stock turbos can generate 20 psi at a lower rpm than the GT35R.

 

yea i know that. i know all about the spool up diffrence

 

It's like the link above states...

Again, keeping it simple... if you had the same car making 300 hp on the 16g at 20psi, the 35r could make 300hp at 10psi.

Now that's not a real life number, it's merely an example showing how much more air the 35r flows.

 

An important fact to remember: PSI is PSI, if you have 20 psi in your tire or 20 psi in your I/C piping. It’s the same thing. What changes is the volume of air. Or how much you are compressing.

 

Lets use a simplistic laymans explanation..

If you have a Garden hose, and a fire hose, both had water spraying at the same pressure, which of the two would knock you off your feet?

Thats essentially the difference.. Though the pressure is the same, the quantity (mass) is greater, but for several reasons, first the size of the compressor means it can scoop and compress more air, also because of its size it can compress it easier without generating uneccessary heat...

Another analogy would be people entering a stadium.. If you had 1 person per second per door... One door is open, its still 1 person per second per door, if you had 10 doors open, it would still be 1 person per second per door.. But the mass is greater (Ten people in a second)

If you try to take that one door, and increase the rate where you get 10 people through the door per second to match the 10 doors.. You'll have a bunch of people running as fast as they can through the door, likely running into eachother and "Getting heated" and you'd start getting less people through the door no matter how high the rate you try to make..


Well.. Kinda.. But I think you can get the point..

Understand?
