Lately I been having some problems with my car from it running lean to other fuel related issues that I seemed to have ironed out. Well I went to the dyno for the 100million time this last month to put an end to the what I had figured out was the intake was not properly clamped down and un metered air allowed to enter the motor in turn making the car run lean/loss of power. Needless to say I wasn’t to happy about the intake being lose and costing me extra dyno money in the process because of the shops negligence to properly clap down the intake but I still should prob put blame on me for not checking over my car before it left the shop. I feel I should'nt have too but will from hear on out.
But on to why I’m posting, everything seemed to be going well and a/f was dead on what my tuner was commanding and I managed with some 18#’s boost to pull on a humid day a 598.9 with 550.5Tq (see dyno sheet). Tq was a little low but I just installed some off-road pipes for my bassani x-pipe and that may explain the loss in tq. So I decided I want more power and wanted to do a nitrous run and granted I have done or been around a ton of nitrous cars/03 cobras with nitrous and have never seen black smoke poor out the exhaust and my tuner said he was commanding 11.1 if I remember correctly. I was in the trunk but it also sounded like the motor was making some funny sounds during the pass also. So after we did the nitrous pass I decided to not try again till I make sure everything is working properly and decided to put down another motor pass just to make sure everything was ok but by now the car was heat soaked and only put down some 575rwhp. Either way I’m not sure where to go from here as I plan on pulling the plugs soon and give them a good look over. Everything runs and sounds fine just was concerned about the black smoke that came pouring out the back. Is that normal with an off-road pipe? Let me know your 2cents
