Actually there was a nice improvement.
I have most of the final numbers and am going to write in more detail in a new thread. But the 2 real; imrovements were a 25rwhp increase and an IAT decrease of 12-15 degrees.
I am waiting on Stiegeneier's notes and that will give me a better picture of the overall results. I will have pictures, graphs and detailed data as soon as I can get it together.
Please be patient while I write it up.
25rwhp not bad :beer:
But for $1000 bucks a pulley swap and re tune would be cheaper
