I watched a video on youtube because I was interested in it. They had a 350 nova and installed it. Then they did a baseline without it and then with it. It made 4rwhp extra. So for just 4 hp I'll save my 300 to 600 bucks.
I understand that on lower comp N/A engines gains are minimal but can be pretty decent on higher comp.
I'm am going to run the snow performance setup on my 12.5 to 1 360 soon and see what it does.
If it means I can run pump gas it will more than pay for itself very quickly.
