I saw one of these called the "NOSxima". A Rental Maxima V6, on the bottle, turning low 13's and blowing prepped Hondas, Mustangs and such
NOSxima ....
Can you spot the NOS hose .. ?
....
Also the Rental Car Nats ...
Rental Neon, using the Windshield washer reservoir as an additional "fuel tank" with a weird fuel, an extra cheap fuel pump connected with alligator clamps to the battery ... Going from highs 16's to highs 13's, all within a few hours ... remember they needed to return the car the next day !!!
