still tuning!
Ok im still tryin to tune my blow thru carb. i tried putting a powervalve in the secondaries and it went way lean. im thinking the fuel sloshes away from the pvcrs under acceleration and causes them to be exposed to air causing a lean conditon. does that sound right? so i quickly put the plug back in. the next thing i did was block the hsabs. i didnt notice much difference. it did get a little richer but its still in the high 12s for afr at wot. i figured the thing should drown w fuel w the bleeds blocked right? im still runnning massive jets 76/93 and a 2.5 pv in the front and the pvcrs are drilled to .136 the wells are .180. i want to up the boost more but the carb just wont flow enough fuel without changing the main jets. the cruise afrs are still around 10-10.5 range way too rich. so im at a standstill for now any suggestions thanks for your help guys!
