Well I've been trying to race my buddy with an ss 5th gen for a while , it finally happened . He is a full bolt on with a Maggie at 8 # he dynoed yesterday at 571/530 . I wasn't expecting to race so I didn't have my bottle pressure up it was around 750 probably. First run was a dig run and I miss 3rd . Well now I know we are getting at it so I flipped the bottle heater on so next two runs psi is at 950 . Last two runs were rolls 20-110 mph this time the nitrous hits like it's suppose to and I pull instantly and take him by about 2-3 lengths . Both cars have tire and I was on e85 and 75shot , very proud of my lil 5.0 doing work against a higher hp boat
