Precision Turbo Talks - Turbocharger Do's & Don'ts

hi I'm Tristan Kimball and on this edition of turbo talks we're going to talk about the do's and don'ts in turbo charging so let's talk a little bit about the do's and don'ts to turbo charging your vehicle more specifically the do's and don'ts for your turbo charger so one of the probably biggest things that we see is oil coking which of course also causes oil contamination and of course this is a majority of time from hot shutdowns so this is when you're out speared ly driving your car and you pull into your favorite store and you just shut the key off what you've done is you've heated up this center section to a very high temperature and you've just cut off the cooling medium so there's nothing passing through it pulling the heat out of the center section the bearings the shaft the oil that is left in there is then of course so hot that it starts to actually cook when that oil starts to bank it becomes a hard type of brittle substance that of course later can break off and go through your oiling system this can cause damage to the bearing system in the turbo as well as even the bearing system in your car so to prevent this just don't shut it off what you're going to want to do is go on your spirited drive pull up to your favorite restaurant and let the car idle for a couple minutes just sitting there idling allows that oil to pass through the turbocharger and allows it to pull some that heat away helping to cool it down before you shut it off it's kind of a simple thing to do and will really extend the life of your turbo so one of the other topics in the do adults is wastegates so obviously if you're running a turbo you're gonna run either an internal external gate and while majority of our turbos run external gates they're not always placed properly you can check out one of our waste gate videos that goes over our waste gates and a little bit of that information in depth but I will tell you that you want to make sure that the waste gate is placed so that the exhaust has a priority flow to the waste gate meaning you don't want to put a waste gate on a pipe directly 90 degrees or even facing away from the exhaust flow because it's going to go past it into the turbo before it gets a chance to actually go out the gate this of course is going to cause some over boosting issues as you know if you're trying to target 10 psi you may end up targeting 14 or 15 psi depending on setup so it's one of those things you really want to be careful of make sure that your waste gates are placed properly and also of course sized properly there's different size gates for different applications and you can always call us here and ask us what size gate will work right for your particular turbo one of the other big things and it's probably one of the big biggest questions we get on regular basis is the oil feed so 90% of the time probably you don't want to use a restrictor obviously there are there are those cases when a restrictor is going to need to be used it's on a case-by-case basis and we do not suggest throwing an oil restrictor in every turbo oil restrictors typically are only used on a ball-bearing system when they are used or recommended you will not want to use one a journal bearing system the drum bearings need the oil much more than the ball bearing systems do and of course you can check out our video on ball bearing and journal bearings for a little more understanding of that oil feeds of course are just as important as oil drains so the oil drain is probably one of the biggest things that a lot of issues and headaches for you know customers with smoking or oil leaking out of the turbo so you do want to use a proper sized drain and a proper size line to allow your turbo to properly drain back to the oil pan to prevent oil from backing up and of course causing smoking and leaking issues we always recommend a dash 10 as a minimum size or 5/8 of an inch and of course if you've got room it doesn't hurt to do a dash 12 or third 3/4 inch line either one of the big things you want to make sure that you focus on is the drain flange itself if you use our drain flange it's guaranteed not to cover this opening if you use another manufacturers drain flange it may be a little bit smaller and cover this opening causing a lip or a shelf here that is going to cause oil to start to pull up which can potentially cause oil to leak and your turbo to smoke so if you're going to use an aftermarket flange make sure that it's large enough to accommodate the other things going to be is the flange itself usually has either a fitting built into it or screw in type fitting for a dash 10 or you know larger line you want to make sure that the inside of that flange and that fitting is large enough a lot of these will be 0.38 oh you know 0.40 oh they're too small and not adequate to actually get that flow out of there we use a high flowing - 10 or B style fitting with our flange and you can purchase those directly from precision turbo one of the last things to talk about when it comes to the turbocharger and of course oil feed and oil drain and the do's and don'ts is crankcase ventilation so we want to talk about that because the crankcase ventilation system is going to affect the drain system on the turbo if you do not have a good crankcase ventilation pressure is going to build up which of course will try to escape out of the engine and you means necessary so it will try to go up the drain line into the turbo when that happens and it's pushing pressure against the drain cannot work adequately and relieve the oil from the turbo and so it will start to come out the exhaust side of the turbo in most cases sometimes even on the compressor side if it's a severe situation so we want to make sure that the crankcase ventilation system is up to snuff we want to make sure that we have valve covers and possibly even blocks you know vented properly we don't really want to use too much in the way of baffled catch cans as they can actually result in holding entertaining pressure so it's a it's good to make sure that you use a good breather system that's well adequate for the motor combination and probably one of the last things to discuss in regards to the turbos is hard piping so a lot of guys will run you know from a turbo directly to a throttle body or from a turbo to an intercooler to a throttle body and when they do this they'll either well of even flange on to the turbo or maybe if it's a larger turbo like a pro mod that has an existing feed band flange here they'll come off of that and they'll weld a pipe from that hard all the way through the system the problem with this is that we end up side loading the turbo so what that means is if the turbo for instance is mounted to the chassis like it is in many race cars or the turbo is braced off of something on the chassis the motor and turbo will flex separately that hard pipe that connects them will now actually put load against the turbo and actually start to flex this cover when that happens the wheel of course touches down which causes damage to your compressor wheel and sometimes the turbo wheel as well it's always best to make sure that either the turbo itself has a coupler on it or in the system somewhere you have a coupler so that you can get that flex and movement you need as the motor and turbo you know move independently the only other way of course to do this is to make sure that the turbo itself is mounted directly to the motor and braced off of it so the turbo and motor move is one unit if doing that the exhaust side of the turbo cannot be braced whatsoever to the chassis because obviously that will add a point which will start to twist on the exhaust side causing side blowing as well so these are just some of the kind of major do's and don'ts with the turbocharger obviously there's a lot of things that you want to do you want to make horsepower you do want the turbo to live a long life and you don't want to have to set it in here for service early because it didn't get adequately oiled or you possibly you know sigh blow to the compressor or turbine wheel so if you follow some of these simple tips they will help you with a long life for your turbocharger and you know have a great time whether it's on the street or at the track making power and feeling boost so that's it for this time on turbo talks i'm tristan kibble we'll see you next time you
