Re: How Much Boost????
We have a customer who we build the engines for in a Daytona we run a 4.625 bore by 4.625 stroke the cyl heads are 125 cc and a flat top piston with one of our custom cams solid roller we run 9.5 lbs of boost with no inter cooler on 93 oct and run 119 mph at 5900rpm it is currently the fastest boat of its size in the Miami area. It has taken quite of work to make the combo work and its all in the cam we have had at least 5 cams before we had this one and I can tell you that the lobe sep has been the key. Ill give a clue its not from 110-114. Sincerely Laz Mesa
