Gotti94 Posted January 21, 2020 Report Posted January 21, 2020 Mods triple port exhaust 4mil stroker crank vforce 4 35mm carbs Play port Domes cut I currently have t5s, is it worth buying CPIs or shears? Will I see major gain going from t-5s to CPIs or shears? new to this. Quote
Gotti94 Posted January 21, 2020 Author Report Posted January 21, 2020 Which makes more power CPI or shears? Quote
gusto Posted January 21, 2020 Report Posted January 21, 2020 How heavy are you? If your a bigger guy go with CPI. Shearers generally make 2 more hp and will rev higher and hit later. CPI usually makes broader power and has a stronger curve throughout. Both have positives and negatives. Cant lose on either... 1 Quote

gusto Posted January 23, 2020 Report Posted January 23, 2020 It’s another pipe for your consideration. kind of similar to your build. Who built your motor? 1 Quote
pp13bnos Posted January 23, 2020 Report Posted January 23, 2020 I'll probably be in the minority here, but on my old setup with a stock ported engine, but with all the bolt-ons, I preferred the T-5s. 1 Quote
trickedcarbine Posted January 23, 2020 Report Posted January 23, 2020 The triple exhaust port work is what makes those cylinders move more then most. If the motor can eat and shit that much, the CPI will blow the T5’s outta the water and have about as much bottom end. Quote
gusto Posted January 23, 2020 Report Posted January 23, 2020 I’d like to know who ported his engine. It many people investing this kind of money in stock cylinders anymore, they just buy a cub. also interests me on builders who add Boyenssen ports and other builder who enlarge the intake instead citing no difference. also jetting differences on the same motor but with a different builder is huge. i guess what I’m saying is ask the builder what works with his porting.

gusto Posted January 23, 2020 Report Posted January 23, 2020 On my 4 mil non triple ported I figured I’d dump by PCs for CPI and have better results. the PCs were better for that motor Quote
specialblend07 Posted January 23, 2020 Report Posted January 23, 2020 Snipers IIRC are like a year wait, minimal gains, and fitment is bad. Quote
kawa110 Posted January 23, 2020 Report Posted January 23, 2020 ^^^for another few hundred $ hand coned LED’s the way to go??? Sent from my iPhone using Tapatalk Quote
