Mazdaspeed's boost??
- Thread starter msp03
- Start date
Welcome aboard...
Although no one is exactly sure what the boost is yet, the common concensus is ~6.5 or 7.0 psi. As far as the ABS, there are no options on the car (aside from color) so the ABS is standard.
Also, you can rest assured that these types of questions have been thoroughly answered before. Try doing a search first, you'll find pretty much everything you need to know.

Some people even say the MSP is running 9 psi...However, we won't get into that because no one is willing to even attempt to understand volumetric efficiency and that fact that Calloway designed a crappy turbo kit.
But, that's not an issue.

How can you judge something you have never seen or touched or looked at before in your whole life? They designed what Mazda let them design. Their manifold is a very good design as a matter of fact. Are you saying that FM's manifold is better? I hope not. Their manifold will get the flow characteristics similar to tubular manifolds. Which is something the current FM manifold will not do or even come close to. The only thing that is bad about the whole turbo kit is the intercooler. Is that what you are solely judging the whole turbo kit on? If so, that's a little nit-picky don't you think. Please tell me whats wrong with the rest of the turbo kit.

Small turbo, cheap piping, small inefficient intercooler...Do I need to go on??
And I have seen it, and I have heard enough to know that what I have is considerably better.
Small Turbo: It is stated in many different articles where mazda personel say that they wanted a small turbo in order to attain almost instant boost and throtle response. This is the reason for the small turbo. It is just your opinion that a small turbo is a piece of crap. This shows you do not know much about designing turbo systems. It's all about making goals of what you want. Mazda made a goal and they attained it.
Cheap Piping: What makes it cheap? The fact that it's plastic? If that's is why you say it's cheap, you are sorely mistaken again. If the piping is made of plastic, it will get next to no heat soak from the engine bay.
Small inefficient intercooler: I'll say that it's small but how do you know it's innefficient? Just because you have hug out with the guys from flyin miata you think you know thermodynamics all of a sudden. You may have heard them talk about inefficiency and you may think you know what it means, but when I hear you talking about it, you dont. This intercooler is probably efficient enough for what it was designed for, the european turbo-diesel. It wasn't designed for the MSP. But I'm sure it does a good enough job for the amount of boost. Also, this small intercooler probably has a low amount of pressure drop, this will reduce lag, or did you already know that.
Moral of the story, the FM kit is a good kit, but it also has it's flaws. It is not gods gift to man. The FM kit you have is designed for profit and performance. Unless a kit is designed solely for performance only, it will always have flaws. You sure do like to knock this turbo kit, have you taken any time to look at your manifold? Not very efficient. It will withstand direct artillery impacts and being left on the surface of the sun, but it's still not efficient. And by the way, the FM intercooler isn't much bigger than the one on the MSP.

All this thought/defense from the guy who thinks the Protege is a piece of crap?!?
First thing, I believe the entire comment about Calloway would fall under my opinion, exactly that...OPINION!
So to answer number one: Yes, my opinion. No where have I professed to know everything about turbos. Yes, it is small...If Mazda wanted that great, I don't, so it is of my opinion that the small turbo is crap.
Number 2: It will flex...So, once again, my opinion is that it is crap.
Number 3: And you know every little bit about efficiency?!? Once again I have never stated that I know everything about forced induction...It is a small and inefficient intercooler, get over it. Yes I have been around the FM guys quite a bit. And in that time I have learned quite a bit. Mazda is looking for bang-for-buck (read as cheapest), not the most efficient piece for their car. At what-ever psi the MSP runs, it isn't the best...And you know it to be the best? How?
Number 4: I know the FM kit has flaws, I never professed it to be the best neither. I do know that OVERALL it is a better design than the MSP. I never said the manifold was the best, and quite frankly, the durability factor far out wieghs the flow. That is my OPINION...
And Mr. Know-All-About-Efficiency, the size of the intercooler doesn't have as much effect as the flow and efficiency does.
So once again, I have stated my OPINION of the MSP turbo. It is great that Mazda went with a turbo for the car. I am dissappointed in what they come up with. Once again this reflects my opinion!
I shouldn't have to type that this is my opinion, it shoudl be obvious because I typed it! My opinion is that the MSP turbo isn't the best they could have come up with. End of argument.
Trust me, 5 to 7psi isn't anywhere near enough to flex hard plastic enough to matter. The only thing that the FM intercooler has over the MSP's is the fact that the numerous short flow paths instead of the long longitudinaly flow paths of the MSP's. If the FM intercooler has internal baffels to direct half the air to half the intercooler, that is also a plus. But I don't think it does if I remember correctly form Patricks.
