The board after mapping

[legendaryslave]

I don't know who has pulled out of this history of back pressure on the turbo diesel engines........... mica we are talking about 2 times !!
I have done many tests on a chassis dynamometer, and with a stopwatch, GPS , the result ? removing the prekat down I have NEVER LOST ANYTHING..... but I only gained the upper , and in the duration of the life of the turbine.
Over the years, I did tests on the drive aspirated and turbo-charged cars and petrol. Very rarely you go out from this rule.

regarding the removal of the catalyst the same concept ? more or less similar? them took over most of the speech, environmental pollution, and the humanities and then in each one ? ****** deciding on us? they want to believe.

to do this test, please remove the exhaust turbine only that Scaria in the environment to see what happens as the car is shit under not, you can go from a diameter ranging from 60 to 200 purging the catalyst for the other test decrease the diameter see what happens you so much backpressure on the exhaust valves.

I forgot it says this character http://it.wikipedia.org/wiki/Equazione_di_bernoulli

don't exaggerate , no one here has told you to go without unloading.

the equation ? certainly valid, but ? wrong applied in this case!!!!! before I open my mouth, I do the tests, I've done, and the results are as above written. NB when I say remove prekat I do not intend to break through and leave them on an empty stomach, this is not ? the maximum. The maximum is obtained by replacing the prekat with a vacuum tube of the same diameter of the original pipe coming in to prekat. That ? it is a tube of the correct diameter , designed by the designers and also according to the bernoulli's equation.

According to me we are not in disagreement , c'? only a misunderstanding .

add: clearly if we vary the diameters , lengths , and anything else (breaking the prekat or the kat, and leaving the stomach empty you go to extend the diameter (to slow down the speed? of the gas) and then again tighten it and this ? very counterproductive. Of course ,compared to a DIESEL particulate filter clogged ? always a paradise. Everything is to see what we are comparing. My tests were done on race engines where it was possible to increase the diameters. Increasing the diameter beyond a certain value (relative!) do not bring additional benefits. Increase huge diameter leads to the problem that you mentioned. But to make the idea you speak of 76mm exhaust on a 1.4 engine naturally aspirated.....
