i am using it... i made my own manifold brace. it works like a charm, but you know i am not a power fanatic nor would i advertise this kit is great for high end power... i mean but basically the kit comes with all of the things you CAN go cheap on, but don't have to... see the turbo and manifold and wastegate and bov don't have to be the most expensive out there to make power... they can be mediocre, but you can't cut corners on fuel management if you want power, and you don't want your engine to blow up.
i am running 7 lbs of boost (0.5 bar), don't know power numbers.... maybe hovering around 200 whp...
this is a more realistic number you could theoretically expect from a kat on .5bar...a lot of kits advertise things like 240 whp.... umm sure you can get that on .5 bar with a whole lot of tuning.
if you throw on a turbo and a fmu and just go with .5 bar you're probably not going to see 240 whp.
see here's how you can ballpark calculate theoretical numbers in hp as a function of boost pressure:
normal atmospheric pressure is around 14.7 lbs... so logically if you double your atmospheric pressure (which is done by the turbo by creating a vacuum), you can double your power as well. so logically by my setup on .5 bar, i would have my original power plus 50% of the original number.
originally i think the 240 may put down around 125 hp to the wheels (this may be stingy or generous, i'm not really sure... it varies by engine and i've never had mine on a dyno so i don't know)...so 1/2 of 125 = 62.562.5 + 125 = 187.5 hp i can expect at my rear wheels.
again this is only a ballpark figure, and doesn't sound like much maybe, but i don't believe many people have a concept of real tangible power... people overestimate their numbers (like nissan does when they tell you that the 240sx has 155 hp... that may be, but only at the crank).
anyway their is an actual more precise formula to calculate hp numbers as a function of fuel and air flow... i don't know it off hand, but it';s fun to go around and call bs on people when they throw out some rediculous number. you can ask them about fuel setup and air flow and determine how much crap they are talking.
there are a lot of people that ACTUALLY DO put down a lot of power with their kat on this forum. ask them about tuning and what not, because they are more apt to tell you what they have done to achieve desired numbers.
i don't tune my car for a number, i just try to make it well balanced, and not overpowered... so i'm not the guy to ask about "hey i want this power, what should i do?"... i can give you advice but i have never personally done dyno tuning and that's where a lot of power lies.
i'm not knocking the guys who do go for big power, that's just not what i'm in to.
ask the guys like structure, ivanatspracing, dwracing, and many more.
also use the search button, there is A LOT of information on this forum that would interest you.
