I finally finished my 540 Brodix I have been working on for a couple of years. I just took it to Edmonton to check it out on a dyno before installation. I am delighted with the results. It makes huge torque and knocks on 800 h.p. I did not run it past 6000 as it is a boat engine. The engine I had previously made 565 so this will be a noticeable improvement. Naturally aspirated, with no power adders. Hopefully, it will be reliable and give years of service.
