Hey everyone-
I work for the company that makes the converters that FC is using and I noticed that a few people claimed that a Random Tech could make more hp...
Well I am here to tell you why I believe that is false.....
First lets look at the facts-
By EPA and CARB standards, the brick must have a density of at least 400 cells per square inch.
Our converters are legal (EPA approved in every state but CA on OBDII equipped vehicles)
So, seeing as we are all resticted to using the same brick, the difference in flow must come from the converter shell design.
1. The first thing you will notice is Random uses a smooth shell, while the FC has grooves in it.
This serves two functions-
The brick is surrounded by a cushioning mat that is 1/8" thick....well what we do is move this mat which is an unpermeable object out of the exhaust flow by putting it in the grooves therefore reducing both turbulence and back pressure.
By putting it out of the exhaust flow, we are also building a more durable converter, because the exhaust is not hitting the mat, wearing it away....
2. Random uses a butt to butt point weld where the pipe hits the converter, therefore creating a sharp edge which does not hurt it so much on the intake side as it does on the exhaust side
We use a 1/2 inch overlap, which not only provides a stronger weld, but provides a much smoother transition from pipe to converter shell.
3. Converter size. Well we all know the FC converter is bigger, well because it is bigger, you are going to have more surface area for the exhaust to flow through.
I am not here to bash the Random converter, just to show you the differences.
These are the main differences, and while one manufacturer can always claim to make more power then another....
We are the only manufacturer that has physical evidence to back it up.
Otherwise given the "right conditions" I am 100% positive we could make more then 7fwhp on a stock Focus.
I know that our converter will outflow a Random tech as a fact.
