---- off dick head....... i found the calculations that i was looking for . no thax to all the douch bags that have negative comments


i hope you find anouther person to hate on. Seems like thats all this forum is good for, that and stroking each other off while watching gay ****

 

if were all so gay why the ---- are you still posting.....

 

So what "calculations" did you find?

Prove us all wrong and tell us what turbo, what engine, etc you are going with, and what calculations you found?

You asked a stupid question to start with, then a few more, and now have found some magical calculations? I doubt it.

Please prove me wrong.

 

That's not completely correct. Nitrous oxide won't change the pressure in the intake manifold so the turbo is going to continue producing the same amount air/pressure so the turbine wheel will need to spin just as fast. The WG will just have to work a lot harder with the increased output(exhaust) of the engine.

 

Correct - what happens is you have increased thermal energy out the exhaust valves in both flow and temperature - nitrous is an oxidizer and tends to accelerate the combustion process nicely. You will need to work the WG harder, aka the wastegate will need to open more to hold the same boost as prior to nitrous. So if the WG opened 1/4" before to hold 14 psi you might have it open 1/2" to hold 14 psi. What you do risk is outflowing the wastegate depending on how much you spray. If you have a single 38mm or internal WG turbo forget about it - you'll be making too much energy to bypass the turbine wheel through that small opening. A TiAL 44mm is pretty much as big as you really need for anything.

You won't get compressor surge, but you can over-boost if your WG is pegged wide open but your energy is producing more energy than can fit through that hole. Another issue is backpressure but that gets complicated.

 

this wont help the turbos effiecency at all will it? like...will a turbo that is maxed out at 20 psi normally be able to create say 30 psi with no2? i doubt it but u never know...

 

No in fact it'll likely destroy the turbo if thats the case. If the turbo is only able to produce 20 psi that means any further spooling should cause it to exceed sustainable rpm and that will shortly destroy the turbo. But for a turbo to only be able to create 20 psi says that the turbo is likely very small and nitrous shouldn't even be considered.

 

i was running a 75 wet shot and 10 on a z6 and fmu



i basically tunned the car at WOT with the fuel jets on the fogger



it was bad ***

 

so... lemme guess.... whats this one rule in the forum about??


way to bring hmt out of the dark ages.

 

I wouldn't agree with this at all. WG sizing depends as much on power as it does on manifold design and turbo size. There are plenty of 600hp Hondas running dual 44mm gates because they run big turbines and exhaust manifolds that give the turbine priority. End result is the WG has to really fight for the air and most of the time loses. Thus needing dual gates.
