2022 LOWRIDER S

Description:

This 143ci got a slightly different combination than the last one I built. The CR515 Cam from A.P.E proved to be a great choice that provides massive torque that is delivered smooth for street riding.

PARTS INCLUDED

With stock valves, the HP is a respectable 156Hp which makes for plenty of fun at the twist of the throttle. I have explained this time & time again but once more for the new viewers. I am located 2200ft above sea level & my dyno readings are therefore 6% lower than they would be at sea level. It is a known fact that you loose about 3% of power per 1000ft of elevation. Me sitting 2200ft above sea is ultimately holding my numbers back at least 6% so the numbers would be sitting around 165Hp & 183ft/lbs. The crankshaft is an OEM one that has been trued up, plugged & welded with oversized big end bearings. The compression ratio of this particular build is 11.7:1 (static) Heads are Stage 2 from Alpha Performance Engines & feature stock valve sizes with hand porting & texturing. The valve springs have been replaced to accommodate the higher lift cam. Link to post about 180hp 143ci: https://m.facebook.com/story.php?stor…
