That is the whole thing in a nutshell regarding JSUP. There are always a certain percentage people who will rebel against a certain product because the majority of people believe that product to be the best in its category.
Let me say I'm currently running Dart Pro One 200cc heads on my motor and making good power. However I'm in the process of building up a new motor for more power and higher rpm and I'm going with the Dart SHP block and the AFR 195cc Competition port heads.
One of the reasons for the AFR selection besides the better combustion chamber design and flow numbers is the light weight valves and springs for higher rpm without valve float. I estimate my new shift points to be around 7000rpm.
I run Dart products and would buy them again but I feel at this point in time AFR has a better product. Simple as that.
I pretty much agree..... I ran Dart cylinder heads for over 7 years before switching to AFR's, I won most of the below trophies with the Dart's, those are not just bracket racing trophies, but also late model Heads-up shoot-out event wins as well. I never had a single problem with them.... I then did the same test that Wes did, except my test was on the dragstrip instead of the dyno.... I went over 2 tenths quicker with the AFR's without any other changes at all..... but that doesn't make me hate the Darts. I had a great time with them, but I do regret not switching earlier, might have been a few more wins if I had.
That's great BB. Worked for you. Does this now translate that no other head will ever produce better results on a given motor? And let's be fair, a 10 year old Dart design (assuming you didn't get the first head off the line) as cast vs. a current design and CNC porting. And you're surprised you got better results? I'm not. Dart claims 50ish HP over their older designed heads to their new Pro1s. Ya think you'd see a change with new Darts? You're basis on this is flawed for that reason. How can you even draw ANY conclusions based on those facts alone. Yet, on that faulty basis, you'll say AFR was better. It does not add up.
Are there guys running Brodix winning trophies?
It's great, you picked up time and credit AFR, as faulty as that was proven above. I'm happy for you. Does this mean you're going to brow beat someone and make insulting comments like "your engine will be a pig if you don't use AFR"?
