2015 Street Glide, 103 CI, ported & polished heads, S&S 585 cam, D&D 2-1 exhaust, High-flow AC - completed at 5,000 ft in elevation (Denver-Colorado)
The Red line beginning reading were with the D&D exhaust, High-flow AC & Power Vision tune.
What level of porting and polishing? Numbers seem pretty modest. If you're happy, that's all matters tho.
First, I told them not to go full power with the tune - I do lots of 300 mile days at higher elevations and I wanted some fuel economy
Second I'm thinking it's abut a 15% power loss between sea level and 5,000 ft
I'm more than happy with the results - otherwise I would have dropped the coin for a 124 S&S if I wanted pure HP
I understand the lack of air at higher elevations but when the computer spits out SAE numbers, isn’t everything factored so charts all across the country are on the same playing field?
I got my last two dynos conducted in Oregon and both times the tuner came out of the room and said today’s air was the pits, but I’m thinking, “the SAE conversion factor would figure that out wouldn’t it”?
