220-230..? what engine u use bro..? ur crank pulley doesnt have any prob. 1 thing u should to know.. lighten- increase pickup... but.. decrease topspeed
on most tri y headers, i noticed pairing of cylinder 1 and 4, 2 and 3 (1-4, 2-3) which forms non-sequential header but i saw some tri y headers have pairings of 1-2, 3-4 which forms sequential header
im hunting for new tri y header but im confused with which one to choose to suit overall street performance output
anyone can enlighten me on the effect of pairings of header primaries on the power curve?
it will be good if i know the difference so i can choose which one is...
