to all the mopar engine gurus can you give me a hp estimate on a 511ci engine iam putting together? its b1 headed- 709 lift solid roller for a procharged application - 9.5 comp. - a d1sc small procharger it will be pushing 12 pounds or air at 6200 rpm on pumpgas

First of all are you blowing through a Carb or not? If so what size carb., if not what size throotle body? Are you planning on intercoooling or using water and alcholol injection? I have built several roots blown street hemi motors for street use, one on pump gas(4,250 bore with 4,375 stroke, Stage V aluminum heads, Mopar iron block, two 1150 Domintor sucking through, no intercooling or alcholol and water injection) and one on race gas, the pump gas motor made 924 HP at 7300 RPM with 7 lbs of boost, the race gas motor made 980 HP at 6500 RPM with 17 lbs of boost If you intercool yours and tune the timing to run pump gas you should be able to make or exceed the same results If you use that much boost and don't use intercooling or water and alcholol injection your probally going to hurt it pretty quick IHTHs My ported B1 heads flow real close to what the Stage V aluminum Hemi heads flowed You really need to watch the manifold inlet temps when tuning a blown motor
