Lococard Member 11 Member For: 15y 11m 16d Posted 09/11/08 01:16 PM Share Posted 09/11/08 01:16 PM Heya,Just trying to understand the workings of the turbo in a mates BA XR6 turbo. The car is modified so here is a picture of the engine bay.In a normal turbo/intercooler system doesn't the turbo spit out hot air into the intercooler, the intercooler cools the air, making it more dense and spits it into the plenum, then into the engine?http://i478.photobucket.com/albums/rr150/heeeryowen/car8.jpgSo, the turbo spits out hot air into the cross over? The intercooler puts cold air into the cross over and then the hot/cold air is put into the engine?How does the CAI come into it?Where does the turbo get air from?Where does the intercooler get the air from?Sorry if this isn't the right section.

Lococard Member 11 Member For: 15y 11m 16d Posted 09/11/08 01:37 PM Author Share Posted 09/11/08 01:37 PM Oh, so the air goes into the front of the turbo, and is spit out the back? A pipe then runs front the rear of the turbo, under it, around near the CAI and into the intercooler?On the rapid systems site they offer high flow and performer. The highflow doesn't use the crossover. What are the benefits of this? Does this mean I remove the CAI altogether? thanks for the prompt reply.

(cold side piping.. and more contineous lengthy pipework) to summerise.. rapids kit shortens the pipework dramatically (quicker air to the engine).. make the pipe larger in diamiter (more air to flow thru), bigger intercooler (cool air a lot quicker and better air flow). hope that makes a lil more sense Link to comment Share on other sites More sharing options...

You still need a CAI as the engine needs air when it isn't on boost? I think.So you would put that under the battery? Link to comment Share on other sites More sharing options...

Guest Guests Posted 10/11/08 12:16 AM Share Posted 10/11/08 12:16 AM Yes you still need a CAI, the colder the air is going into the turbo/cooler, the colder it is coming out. Big cooler, srort pipework & a big CAI is the best bet mate Link to comment Share on other sites More sharing options...
