no matter where its mounted your supposed to have a blow down tube. I told him send it up in my buddy's car since he doesnt want to run his cobra (97 stuck in the 14s on street tires). After tech to mount it and he doesnt plan on spraying it till the end of 2nd and through 3rd since hes on street tires so should only run mid to low 12s tops i'd say (6.0l with a very small cam)
