Tuning with tri-y headers

REGGIE WINKLES · 08-06-2015, 02:16 PM

When I switched to Tri-y headers I had to richen the carb as they like more fuel. My car is a stick which may vary from auto trans car. Those headers were worth about .05 overall after tuning on my application. 4-7 swap cams will not work with Tri-y's. They really pick up the 1/8 time, not so much on the top end of 1/4 tracks. Overall they are an improvement, but for my 2 cents I would say they perform much better on auto trans cars than with the stick. I don't know for sure, but have heard anywhere from .10 to .12 on auto trans car. Hope this helps.
