I just finished up a cam swap on my 2000 Camaro. It made 322 rwhp with stock cam, so I'm guesstimating as high as 375rwhp when it is re-tuned. (Guessing high to be safe)

From what I have found, the 2000 LS1 F-body has 26.6# injectors.

I also have an NOS #5177 dry kit for the car, which is capable of 100hp according to their advertisement/claims.

Assuming car can be tuned for 75-100hp nitrous shot, am I asking for trouble with stock injectors or not?

I'd rather scrap the whole nitrous idea than to start buying bigger injectors, fuel pumps, etc...In other words, I do NOT want to open up a whole can of worms and start on the slippery slope of spending a whole lot of cash, just to be able to spray the car once or twice a year at a test and tune...

Thanks in advance.

 

you might be able to run nitrous on the stock pump and injectors...BUT...I would not suggest it.

The stock fuel system is only good for around 450whp....with the fact you are getting a new tune the only costs would be the injectors and the fuel pump.

or you could just jet the nitrous system down to 50-75hp...depending on how the car is reacting to the nitrous as far as air fuel ratio and fuel pressure.

 

wouldn't the best thing to do in a situation like this is maybe upgrade your current setup, add a fuel selanoid etc? im sure you could put something together for him.

 

converting to a wet system would be an option but I would still reccomend upgrading the fuel pump.

A dry to wet conversion would be around $200
Racetronix Kit $249 (650whp)
A Walbro 255 alone is around $150 (550whp)
Injectors $350

If it was my car a fuel system upgrade would be one of the first mods I did....without a good fuel system you are severely limiting your options.

 

Thanks for the replies so far guys.

I actually have an external pump that I got along with the used nitrous kit.

If you are using that pump inline with the stock pump...you will still be limited to the flow limits of the stock pump....this can also create cavitation at the stock pump as you are trying to pull the fuel faster than the intank pump can flow.

 

You also need to tell us what tranny you are running, since the fuel requirements are determined by flywheel HP, not rwHP.

FWIW, my stock fuel pump would drop psi at WOT with my stock engine and a 125+ hp shot. I can't imagine your setup would work with the stock pump, let alone the 24# injectors.

 

sorry dont mean to hijack but I am making about 580 fwhp and plan to run a 150shot on top can my racetronics 255 kit support that?

 

most cars have been able to support 6-650rwhp on the racetronix systems.

For your application I would suggest running a dedicated nitrous fuel system...this removes the nitrous system fuel demands from the main fuel system, and lets you run higher octane fuel only when spraying.

I run 93 octane in the main tank and C16 in my dedicated.
