should adding NOS decrease HP/TQ by 35% when NOS not activated?

[Brainhulk]

So apparently afr/timing changes need to be made to run NOS safely. Therefore when adding NOS, overall engine power should decrease in exchange for the couple of seconds of fast and furious mode.

 

[sporkface69]

If it happens IRL, then yes.

I think 35% is too arbitrary of a number though.

 

[Dwight_C]

35% is a bit much, but I like the idea, because then people will be discouraged from using it willy nilly in online races. I like drag racing online, and will only use the nitrous in that application, but it would be cool to actually have to tune your engine to properly run it.

 

[ace004]

Isn't that all done electronically now on the new cars/systems? So you switch it over with a laptop and the fuel trim and ignition timing changes when your nitrous tps sensor activates? Does anyone hear actually run nitrous?

Not on old OHV carbureted setups. On my cars, I twist the distributor, and jet up the carb. I'm old school. Hahaha

Well yeah, in carbureted vehicles those gismos don't work, but with EFI I think we are beyond that. Although I could be wrong, I don't have nitrous on my personal vehicle.

 

[Falango]

I don't understand why I'd fit nitrous to get back power I'm sacrificing to have nitrous...........
35% seems a bit drastic for that......

On late model cars, its as easy as plugging in your tuning suite, and telling it to run nitrous. Many modern cars have knock retard which retards the timing in order to protect the engine from detonation. I'm sure that modern stuff could run at normal timing, and then retard the timing and increase fuel as soon as you hit the button. So technically, you would drive around normally, and when you hit the button, the computor would automatically make the necessary adjustments. This is theory mind you, I've never sprayed a cpu controlled car.

see that's what I thought from my past reading on the subject. Thanks for clearing that up!

I don't see the point of adding a handicap with NOS, if this is what I understood. There should just be an option to disactivate NOS online (a possible restriction like other restrictions (TC, SFR ...))

 

[Jay]

No, if the Nitrous is a wet system then the fogger will take care of AFR.

 

[Gturbo5]

20% Cooler!

 

[Aloha62_2]

35%!!!???!!!

Those changes would be closer to 3.5% and tuner ECU's with modern injection systems are more then capable of fully compensating as required resulting in no loss of power.

 

[Brainhulk]

35% is an excellent number, the gain will surpass that when activated. It will discourage use in circuit races and will only be advantageous on short drag races.

And cars with turbos should only be able to race with two tyres when not on boost. After all there is nothing like a penalty with no basis in reality to balance things.

Adding turbos affect PP. Nitrous apparently does not. Where is the balance in that.

surely adding a fixed PP penalty and a weight addition* for a car with nitrous installed would be easier and more balanced then an utterly bizarre massive power drop.



*I have installed them, the full kits can add up to be fairly heavy.

I would go for that also. PP and weight penalty. If not, there should be a power penalty when not activated
