B00STDZ Posted April 25, 2009 Share Posted April 25, 2009 Im looking at getting my intake(n42 on l28et) ported and I was wondering which method would recieve the best results... I've heard of a method of some type of special "clay" being shot through the intake to smooth off the inperfections inside the intake. Then theres the basic job the die grinder. Some people I have talked to have said it is better to leave the intake "rough" for something for the air to "grab" to maximise the air/fuel mixture. I have porting the intake opening to 60mm with a die grinder as of now. Some people commented about not being able to fully port the intake to 60mm? I had no problem. Ported it 60mm straight through with no tapering. Tell me some setups you guys have used and the results it achieved... Quote Link to comment Share on other sites More sharing options...

A special medium is forced through the manifold to remove roughness and improve airflow. An EFI manifold like the one you have is an air only design. Fuel is added at the head/manifold junction by the direct port injectors. A wet manifold, such as one that uses a carburettor may benefit somewhat by keeping the manifold interior 'rough' Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted April 25, 2009 Share Posted April 25, 2009 Extrude Hone is quite expensive. If you can weld or have a buddy or local weld shop, you can get a bigger manifold made for same ballpark cost. Quote Link to comment Share on other sites More sharing options...
hughdogz Posted April 25, 2009 Share Posted April 25, 2009 It's been discussed before: http://forums.hybridz.org/showthread.php?t=132014&highlight=porting Most notably, Monzter (and 510Six) have a really good solution: Hope this helps, -hughdogz Quote Link to comment Share on other sites More sharing options...
