Message: <blockquote data-quote="speed2horizon" data-source="post: 3473373" data-attributes="member: 30831">Agreed on the human nature... When the feel the Gs, the wanted more... But BOT is not the easiest way.... Requires alot of calculation in terms of cost and design if to be done properly...From my opinion, NA car should be left it to be NA. BOT to the engine is not a good idea. If want to make it faster, do it the NA way, by increasing the combustion power at atmospheric pressure. Yes... Very true Supposedly, All engine are designed to work under normal atmospheric pressure. But they are able to work under abnormal pressure condition due to the correction factor on the ECU mapping... And NA Engines (normally aspirated engine) also known as vacuum engine provide suction when the intake valve opens as the piston goes through the intake stroke. This will create a vacuum condition on the intake manifold. However, FI Engines(Forced induction engines) like Supercharged/turbocharged engine forced the air into the cylinder instead of suction from the cylinder. Let say, boosting at 1 bar into the cylinder(1 bar higher than atmospheric pressure) and being compressed till the top dead end, say CR10, the equivalent compression ration would be 20:1... NA means breath normally-suctionAnd yes, Turbocharged will generate more heat and stress to the engine compare to NAs... If we're talking about road cars.... Don;t quite agree with metal gasket. Thick metal gasket is just a way to reduce th e compression ratio. Instead of changing pistons that required more cost, time and hassle. If someone's gonna use metal gasket of 1mm, there's actually not so meaningful. If you buy original GSR topset from MMC, the gasket is also silicon carbon.Management is not so accurate. I would say the ecu mapping.The material could be the same, but the design of the rib bone of the engine might be different... Water cooling system in the engine block are the same, at least for mitsu... Dunno about others... But the water pump might have different capacity. Hoever, radiator are bigger as for some turbo charged engine. But not necessarily. Wira 1.6 Auto has the same radiator size even compare to EVO... Hpwever the fan are different.NA could be fun when things are done in a proper way. However, it may cost more than a engine transplant.in some cases.... But the process of BOT is amazingly fun... Alot of "suprise".... Hahaha...Bump: AGREED, NA modification will cost more to achieve the same amount of power compare to forced induction engine.Not quite agree. The ultimate driving machine on track today is still NA. The Formula 1.... Tell me which 2.4L forced induction engine in the world generating 900-1000Bhp wthout lag.... F1 does.... Kakaka.... Turbo is just another way of increasing the capacity by increasing the intake pressure when needed... Oppsss.... I meant when wanted.. hehee....Carbon itself is an insulation bro... Ppl uses carbon hood for the lightweight... If BOT are measured and done properly, the heat issue can be resolved. If not taken care properly, even NAs can overheat...Not agree... NA has its fun too... 2 different thing... There is no right or wrong... Purely personal preference.. YES!!! BOVSOUND IS DAMN FUXKING AWESOME.... not SQV for me.... again, just personal preference</blockquote>

Ball bearing turbine

I am currently running on ball bearing turbine. I wish to send my turbo for cleaning.. is it possible? I know its not servicable.. but how abt cleaning, re-grease it.. or balance it? Possible? Location in JB.
