Compared to the cast killerB collector. The original hand made one has the awesome low angle merge.

Of course it can be overdone. The FA headers coming onto the market are a perfect example of horrible merge collectors. At some point, you are forcing gasses into other primaries, which is not ideal for unrestricted flow. Quote:
Where the cast collector really shines is in that it is a true high velocity merge collector. This is something that cannot be accomplished with tubing. Prime can chime in here, but IIRC we picked up ~15whp and a decent amount of response swapping to the newer casting design. I expected 3-5whp, so that was a pleasant unexpected surprise, and something we've never outwardly advertised. This was on one of our shop cars that at the time was ~400whp. We've got a backlog right now, but I do have a lightly used latest version on the shelf if Prime needs one for comparison. Let me know. |

Jr keepin it REAL.
Seriously though I don't know who they think they're fooling with 70whp gains over another aftermarket header... oh wait there's actually a handful of dudes on this thread that got bamboozled Also user, what about the most conniving and evil company in the industry no longer in existence? |

How much of an effect do the multiple joint welds have on flow and does having the brace welded from the exit to the header flange put any undue stress on the assembly at higher temps, from expansion? Do the welders smooth each joint on the inside as they go? I remember seeing the full race header and thinking how awkward they looked with all of the welds, and wondering the same.

I personally don't think we are trying to "fool" anybody. We were told by this company that they would produce some third party testing. These are the results they provided us. Which is why I sent another one to Jr. free of charge for more testing. Pretty simple

If it were only that easy
How good is the fit-up? Having this many welds is good and bad. A benefit is that it allows you to move things around to compensate for manufacturing deviances. A bad side is there are WAY more opportunities for less than perfect fit-up. Another bad thing is the fit-up will not be ideal. Look at the pics. Everywhere a straight tube leg meets a bend, there is a size difference. That's not only on the outside. That's because when tube is formed, it goes out of round and the wall will thin and thicken. It doesn't matter if you use mandrels made by NASA, stubbing a straight leg to a bend will do this and no matter how good the welder is there will be a transition where they meet. The ONLY way around that is by forming primaries/secondaries from a single tube. Another benefit is cost. When you buy off-the-shelf elbows, straights, flares, etc... it's way less expensive than investing in custom tooling testing and repeat. Even if this header doesn't make power up to it's claims, if the quality and long-term reliability are there, then the price will make it a good seller. |
