Hemi Posted October 1, 2008 Share Posted October 1, 2008 surge happens when the turbo can make more boost and is restricted to less that the surge line amount via wastegate or inlet (not pressure side) restrictorit surges because it cannot maintain less that that pressure at a flow less that that value and more than 0 as it spools it hits a point were there is not enough ex gas to force compression but enough to make some pressure but not maintain it so it surges to presure...then the pressure overcomes the turbine drive and stalls the compressor because the motor is supercharged it has far more ex presure than what a normal engine of a given size woudl normally have so sized correctly you wont have the intake pressure exceed the given turbine power compressor maps are a good basis but you need to overlay them with turbine maps and engine flow to get a idea on what it will do you still need to size your turbine/compressor combo corectly for the application and twincharging will not bode well with a poorly designed setup just my 2 cents ive written this as simply as i can so everyone can get a idea of what im saying ..so somethings are not exact for teh sake of understanding cheers even i understanded that , good show old chap Quote Link to comment Share on other sites More sharing options...
fishtailfred Posted October 2, 2008 Share Posted October 2, 2008 I didn't read the thread, but anyone considering doing an SC/turbo project should strongly consider building one of these instead : If I can't get my ute sliding how I want it to, I'll be trying that as the next step.
