I pmed area47. The harrop is a ton of fun don't let anyone fool you by HP numbers. They don't mean ****. I dynoed my car at 222 with stage 2 and I had a 14.0 quartermile. If 12-14 psi is just doing that at 222...then 26psi that I had on the harrop with the 2.75 can really make things interesting with those larger injectors.
