Guest shuyun Posted March 23, 2003 Share Posted March 23, 2003 Does anyone cool the exhaust with a heat exchanger. I have found some that cool the exhaust gases going back into the intake but i have not found anyon cooling the exhaust into a turbo charger.

Cody 82 ZXT Posted March 23, 2003 Share Posted March 23, 2003 Why would you want to cool the exhaust gases going into the turbo? You not only need the pressure or flow of the exhaust to spool your turbo but, you must have the heat that is provided by the combustion process. You need to do what ever you can to keep the heat in the manifold so that it can flow through the turbo. After that who cares what happens to the heat. Many people coat thier manifolds with Jet-Hot or similar products to help spool time of the turbo and to keep heat out of the engine bay. It just so happens that it looks cool.

Guest shuyun Posted March 23, 2003 Share Posted March 23, 2003 No if you can take the exhaust gas coming off the motor from 1200F to 900F with a heat exhanger before it goes into the turbo the turbo. what affect would it have oh the heat put into the fresh air as it is it run through a trough the turbo.

Cody 82 ZXT Posted March 23, 2003 Share Posted March 23, 2003 If you weree to reduce the tempature of the exhaust before it enters the turbo it would have a negative effect on the performance of your vehicle. Once again you must have the heat aswell as the volume or flow of the exhaust to power the turbine blades. I really suggest you do so reading on turbocharging. A good book on the subject is Maximun Boost by Corky Bell. You can pick it up at your local book store for 20 bucks or so. I do think I know what you are trying to do. Let me see if I can get it right. You are wanting to lower the tempature of the intake air by lowering the exhaust gas temp. First off the intake and the exahust sides are totally seperate from one another. The heat in the intake air comes from the compression of the air not from the hot turbine section of the turbo. If you could change the laws of nature you could make the intake be as compressed as you wanted and not have any heat built up. Since you can't change these things you have to run an intercooler to reduce the intake tempature to a manageable level. Your right in thinking that cooler air is better but, cooling the exhaust side is not the way to get there. Have a good one. Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 23, 2003 Share Posted March 23, 2003 Hot expanded air = fast air The only issue with heat is you need to keep it down obviously to not destroy the turbo, if your running very hot though then I'm going to guess your lean or the timing is off.
