AudiDudi observes >>>WOT in low rpm's more than high<<<
>>>We are talking about I5t<<<
First point, I agree. Second point, I was referring to the guy
that had the nitrous on an I5 NA that went to Mexico on him.
Up front, I admit [as I did earlier] Nitrous CAN be great. I
have just never experienced it to aid low end around town power--nor
would I [personal preference only].
Nitrous does chill things a bit. Observe temperature of air
exiting supercharger about 100 degree lower, when nitrous injected in
front of the charger. W/ a charger and nitrous, you must of course
increase fuel pressure and delivery. Brave? Put a wet nitrous system on
outlet side of charger--cools air more as adds more fuel. Remember, if
nitrous is used regularly on street/strip GENERALLY want to drop to spark
plug at least 1 heat range colder than stock--help control
detonation--hopefully. ALWAYS use the highest octane fuel avail. AVOID
AvGas, if you were not already.
Most likely you will need to retard timing a bit. Bigger the HP
advertised, more retard. On turbo, you are prolly gonna put fogger ahead
of throttle body [I THINK you MAY see boost increase--which can be good
or bad]. You really must watch for lean burn here.
Nerdy fact: More air [23% oxygen by weight] = more fuel can be
combusted. One pound of Nitrous [36% oxygen by weight]. So, benefit of
nitrous comes from the fact that it provides 56% more oxygen in 1 pnd
unit. O.K., for the scientists out there--these are close, right?
My old experience w/ the laughing stuff, and the reason why it
does not appeal to me as a low end solution, is that [and this varies on
amount, where fogger placed, wet or dry, etc.,] nitrous comes on with all
the charm of a knee to the spuds. I'm sure this has been engineered around.
Does it work. No doubt. One reason the NHRA banned it after
1982 season--works bigtime on forced induction motors. But, I tend to
view things with ol' Mr. Murphy in mind: if it can go wrong, it will go
wrong at all the wrong times. Preference differs, but I would not have
nitrous on my everyday driver if it was installed for free. I would love
to have it on a weekend road / track car [like the TQC I am looking to
steal]. People use it in everyday drivers, just not me.
I do agree with the earlier post that the tech guys at NOS [see
any car mag] are good
