flatback90 Posted March 23, 2008 Share Posted March 23, 2008 do intercoolers have to be blow thru or can they be suck thru? ie instead of filter/turbo/intercooler/inlet can it be filter/intercooler/turbo/inlet or am i being stoopid? Quote Link to comment Share on other sites More sharing options...
Matt Neale Posted March 23, 2008 Share Posted March 23, 2008 do intercoolers have to be blow thru or can they be suck thru?ie instead of filter/turbo/intercooler/inlet can it be filter/intercooler/turbo/inlet or am i being stoopid? Not really a stupid question - but: The whole point in having an intercooler is to cool the air that's been heated by the compression action of the turbo. Therefore if you plumb the intercooler in upstream of the turbo, there is no point in having it fitted. Matt Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted March 23, 2008 Share Posted March 23, 2008 ^^^^^^ What he said. the intercooler is there to cool the compressed air, so by fitting it up-stream of the turbo you'll have a system with no functioning intercooler in it.

landrover598 Posted March 24, 2008 Share Posted March 24, 2008 Whilst we're on the subject. How much of a power loss would there be on a 200tdi if there was no intercooler. Quote Link to comment Share on other sites More sharing options...
western Posted March 24, 2008 Share Posted March 24, 2008 probably the same as if the intercooler hoses weren't fitted & turbo drew straight from the air filter. Quote Link to comment Share on other sites More sharing options...
thirstybeast Posted March 24, 2008 Share Posted March 24, 2008 Whilst we're on the subject. How much of a power loss would there be on a 200tdi if there was no intercooler. Power loss running without an cooler isnt that much, they are a relativley modern must have item. Most of the large machines I look after (Cat D8,Cat D6, Cat963, volvo A20) dont use an intercooler. I know they were designed without them while a TDI is meant to have them. My intake manifold temp is higher by about 30 degrees C than an inter cooled model (I checked) but the vehicle compares well to other TDI's I regularly drive. I like the idea of a small fan cooled system and may have a go at that. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted March 24, 2008 Share Posted March 24, 2008 turbo drew straight from the air filter. It does doesn't it ? or have I missed something obvious here Mo Quote Link to comment Share on other sites More sharing options...
western Posted March 24, 2008 Share Posted March 24, 2008 as like the old TD engine [i.e. NO intercooler] Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted March 24, 2008 Share Posted March 24, 2008 But surely all LR turbos draw straight from the air filter Mo Quote Link to comment Share on other sites More sharing options...
western Posted March 24, 2008 Share Posted March 24, 2008 But surely all LR turbos draw straight from the air filter Mo not directly, cos the intercooler is in the intake path. I mean like air filter unit/connecting hose/turbo compreesor Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted March 24, 2008 Share Posted March 24, 2008 But Ralph, don't they draw from the air filter to the turbo to the intercooler to the inlet manifold ? Mo Quote Link to comment Share on other sites More sharing options...
landrover598 Posted March 24, 2008 Share Posted March 24, 2008 Air filter > turbo > intercooler > manifold Perhaps i'll try running the tdi without the intercooler for now, and see how it goes. Quote Link to comment Share on other sites More sharing options...
