Dynoed my car with nitrous heres the #'s Hey guys i got to dyno my car yesterday. I wanted to have a stock baseline run, before i install the mods. i recently installed the nitrous kit. here are the numbers.
Stock baseline 2001 C5 corvette no tune 314 rwhp and 322tq
Stock baseline 2001 C5 corvette no tune with 100 shot 397 rwhp and 412 tq
I was reeally worried to run the nitrous but my tuner said it would be ok for one pass.
Next mod im in the process of installing:
LG Headers
TR6 Plugs
and going up to 150 shot tuned of course.
You guys think ill be ok with 150 shot?
And thanks to all the fellas that helped out on this board.

You need to be carefully what you say to people on the board. Just cause your car runs fine a 150 shot doens't mean someone else will. Every car is different! If you want to be safe depending on your injector duty cycle you could step up to a larger injector and a 255lph pump. I would rather not see someone blow their motor up because someone else said their car ran fine and 150shot.

That some kinda new democratic economic math???
397-314=83 HP Gain
412-322=90 TQ Gain
A 150 wet is doable with a Stock C-5, just have all the safety's in place and monitor AFR and Fuel Pressure.

Beer, by my calculations you would be correct.
Like some of the other guys said. Monitor your A/F and fuel pressure and you will most likely be fine. I am guessing you were fat with the stock jetting on your kit. Thats why you didnt get the full 100 rwhp, but your at a good starting point.

No you did nothing wrong.
Jetting is generally rich (the recommended jetting that is). Best bet is to log and shoot for under 12 for AFR when on spray. You can do this by increasing or decreasing the jet size on say the fuel side to tweak the AFR to get it say right at 11.5 or maybe 11.8.
If your AFR was say 10.7 when you sprayed on the dyno, changing the fuel jet down a size or two will bring up the AFR to the 11's and you will likely show more power.

Don't worry so much. People use nitrous at their own risk, and it is pretty well understood that these cars can handle a 150 shot.
If it breaks it breaks. The user should know this, and is clearly assuming any risk by modifying the car. Is nice that you are concerned, but we are all big boys here.

Just like everyone else said, most kits have a recommended jet size that is on the conservative (rich) side. You are certainly not doing anything wrong. Thats pretty much where everyone starts. To get the full 100rwhp, you would need to go with a smaller fuel jet. This will increase your A/F ratio and bump up your power a bit.

Hell yea it can support a 150rwhp shot, all day long, but that is given a good tune which covers all of the parameters needing coverage IE: timing, fuel system, a/f ratio, safety devices, plugs, gas and so on. Then later when your more comfortable, moving to a 200 shot is certainly doable; but the risk factor does move up; however, with a spot on safe tune and all of the safety stuff (a/f ratio lean/rich shut down feature is a beautifull thing) we can live a nice long safe life even at 200 with a stock motor. Just make sure your knowledge bank has had a few deposits made before moving to the 200 and you'll be fine.

Dont be fooled by the information listed above. The info on jetting above is great info but please do not assume your car is rich and go down on the fuel jet with out knowing your airfuel or reading the psark plugs. Factory suggested jetting is not always on the rich side and in some cercumstances is actually dry. If you assume its rich and do not know for sure and go down on the jet it could cost you a motor..
As to 150 being safe. The 150 hp is what we suggest not going over for safety. Anything over that you are taking a risk and putting extra strain on the motor it is not rated to handle. Take that risk knowing you can afford to fix what breaks.
