Question Dyno HP curve on a nitrous engine

Does anyone have a picture of a dyno print out of a nitrous engine run without using the nitrous?

Reason being, I ran my Chevelle on a chassis dyno last week without using the nitrous. The engine is setup for nitrous but I am unsure about the exact specs on the camshaft. I basically want to compare my dyno results with someone elses and see if my results are what I should expect or if they show a problem with the engine.

thanks.

Here's mine: http://www.go-fast.org/z28/photos/nitrous/n2odyno.gif

You'll see a stock LT1 dyno, then my 383 NA, then the 383 with about 175hp of nitrous.

thanks kmook !

Those dyno results are nice, thanks for sharing.

My N/A dyno sheet looks nothing like you guy's N/A runs, both HP and TQ were alot different. Do you guys have NITROUS CAMS in your engines or are they regular cams? cause I am really looking for dyno results from a nitrous engine off the spray.

I am getting my webspace setup to host some pics. Then I can share my dyno results with you all.

What kit are you running, those torque numbers seem very low for a 175 shot.

Not a kit, just parts. But NOS Cheater solenoids, if that helps. What kind of torque gain would you expect?

Looks like my old car when I got it done except my fuel program was set up too rich and that will cause a torque drop.
