Valadezj Posted March 13, 2013 Report Posted March 13, 2013 Is anyone interested in trading your small bore inframe shearers for a chrome set of small bore inframe cpis. Shearers must be chrome and small bore. PM or text 480 543 8736 Quote
Wildcardracing Posted March 13, 2013 Report Posted March 13, 2013 Jose, That cub you bought is ported for the CPI's. Might want to hang onto them. Just sayin. Quote
Valadezj Posted March 13, 2013 Author Report Posted March 13, 2013 ok kool, will do , i was just second guessing because everyone keeps saying shearers give 7 more hp on certain applications. Quote
special06shee Posted March 13, 2013 Report Posted March 13, 2013 cpis are great pipes!! i had them on a redline ported cub. it was dynoed with the shearers and cpis. the shearers made (if i remeber correctly) 1-1/2 hp over the cpi's and had a bit more over rev,BUT, the cpi's pulled more hp and tq all the way up the front side curve until almost 9k. in my opinion id take a broader curve any day vs a couple hp gain up top! now on my 10cub the shearers made 10hp over the cpis and more or less had the same curve down low as th cpi's.. every motor will like a certain pipe better then others 1 Quote
