Let me preface this by saying that JUN3 are great camshafts and rightly so because most people have not found camshafts that make better power. This does not mean it can not be done. (Important lesson here: DO NOT LET THE LIMITATIONS OF OTHERS LIMIT YOU).
Before I go into specs and details, RM is and will always be grateful that the owner of this motor Arno (98itr484) for putting together a bad ass motor and gracious enough to share his dyno tuning sessions. THANKS ARNO AND FRIENDS!!!
I expect to see a 25 - 28whp gain from the m22 cams / Rocket Head
So far Arno is 10hp over his previous setup even with the stock injectors maxed out and the run cutoff at 8.0K due to fuel starvation.
