Message: <blockquote data-quote="xtremeleo" data-source="post: 1554005" data-attributes="member: 18941">bro, iam not againts std gasket. iam using one wit higher boost level (witin limits, of course :)), and never changed the std gasket in the engines dat ive mod previously even when using bigger turbines. its not impossible to make a lot of improvement just by boost alone, but the consequences have to be taken into consideration ie can ur ignition timing retard fast enuff when the strong boost of a bigger turbine kicks in? FYI, an L2 turbine, even boosting at the same level as say a TD04, but there r sum difference in performance (usually big difference since the turbine's sizes differs a lot). TD04 is gonna lag kaw2 compared to the puny L2's turbine (obviously, ya?), but once it kicks in, 1 bar is gonna fly across the boost meter, compare dis to d capability of the L2 turbine, which wud not have the same charging capability. charging slowly wud let ur ignition timing retards in time, but will it react the same wit a TD04? dats the million dollar Q, much will say sure can maa.. but in a millionth of a second, can all ur sensors give inputs to the ECU quick enuff to avoid ping which is a sign of detonation? ping doesnt only occur when u can hear it, unless u have a ping detector u wont know if it happens in the slightest.the ignition timing part is one of the part u have to look at carefully bro, not simply boost out of the safety range and expect it to be safe, even if ur boost meter gives the same reading. 1 bar is 1 bar, but wit different turbines, the effects vary greatly wit the turbine capability.just be careful k, much poeple doesnt say y their engine goes kaboom, they wont say its because of their mistakes, ie changing to bigger turbine, boost kaw2 and forgetting the tuning part. they ll say, its the mech's fault, wiring, etc.iam wit std engine rite about now, and booting it hard on cold nites gives me boost cut at only 0.96 bar (reading is from a blitz electronic boost meter), as fast as i let my foot down. dis wudnt have happened when booting it on "hotter" (comparatively) nites, just to give u a glimpse on how safety is taken care off in a std system. FYI, my MAP sensor is good enuff for 1 bar application, so y did it alwiz cut fuel on 0.96 on colder nites but on hotter nites boost cut comes in at 1.12 bar? remember, dis happens wit the SAME turbine, but the effect is quite noticable.. because the air is more dense on colder nites, and charging a certain volume of air lets more oxygen molecules into the combustion chamber in a given time, or more oxygen per CFM on colder nites. CFM stays the same, but oxygen level increases per pulse of air charge. u get me? compare dis wit a TD04, higher CFM reading then the RHF5 (is dis the right series for the L2 turbine?), and charging colder, more dense air at 1 bar compared to the RHF5. whaddaya think is gonna happen? eliminating ur safety feature isnt a good thing, as a reminder bro if u really gonna boost 1 bar on dat TD04.. unless u have the other vital parts sorted out :)</blockquote>
