what are the rules for nitrous at PRP? we’re going to be running a 75 shot of wet NX. i heard about a blowdown pipe? anything else needed? also we’re going to be running the nitrous feed line thru a hood in the chassis and underneath the car, is this allowed? ---

this is from the NHRA. i’m not sure how that applies to PRP. Nitrous Oxide The use of any agents other than NOS as part of, or mixed with, this pressurized fuel system is strictly prohibited. All bottles must be securely mounted, stamped with minimum DOT 1800 pound rating, and identified as nitrous oxide. Nitrous oxide bottle(s) located in the driver compartment must be equipped with a relief valve and vented outside the compartment. System must be commercially available, and installed as per manufacture’s recommendations. Commercially available thermostatically controlled blanket-type warmer accepted. Any other external heating of bottle(s) prohibited. ---

> and run consistant with auto tranny Yeah, good luck with that lasting. Most automatics that are mated to 4 poppers aren’t designed to handle much torque. Nitrous injection tends to make 1.5 to 2 times the amount of torque as horsepower (for example, a 100 shot on a mild 5.0 is known to make 200lb/ft of torque). I’ll predict right now that the transmission won’t last a month. 😃 ---

Nitrous is VERY torquey indeed. Try boost where it comes on a bit slower. IF you are bracket racing then you don’t need nitrous anyways. ---

well we just want to see what the car will do with spray… its said straight from GM that the motor can hold up to 250whp with stock internals, so im guessing around 300lb tq ---
