510six Posted January 18, 2009 Share Posted January 18, 2009 This is the flow sheet for a N42 head ported by Tim Kerber at http://www.airflowperformance.net , I am hoping to make 500rwh with a non EGR N42 ported and ceramic coated intake using E85 as fuel under boost. A T67 turbo is used attached to a stock turbo manifold with the exhaust flange relocated, the exhaust manifold is ceramic coated inside and out as well. The cam used is a secret split duration WEB unit, that works quite well for a street/strip application. I can say that the lift is close to .500.

ktm Posted January 18, 2009 Share Posted January 18, 2009 Nice numbers. Are you sure about the website address though? I keep getting sent to some generic page. Quote Link to comment Share on other sites More sharing options...
TimZ Posted January 18, 2009 Share Posted January 18, 2009 Interesting- those numbers are very similar to the numbers for my N42 - the exhaust is almost exactly the same. That should work very nicely for you. Have you considered coating the chambers and exhaust ports, too? Quote Link to comment Share on other sites More sharing options...
jc052685 Posted January 18, 2009 Share Posted January 18, 2009 generic site and my web blocker informed my of a possible threat. hummm good numbers though!! Quote Link to comment Share on other sites More sharing options...
510six Posted January 19, 2009 Author Share Posted January 19, 2009 Tim Kerber`s website is currently down for construction, it should be back online in a week or so. Sorry about any confusion.Tim, the chambers and the ports were coated on my last N42 head and the exhaust ports and combustion chambers will be coated on this one as well. Tim Kerber sonic tested the exhaust ports on the N42 and tried to make them flow as well as possible.He also gasket matched the N42 intake to the head as well. I am quite happy with the results, should let the T67 breath better on the top end. Quote Link to comment Share on other sites More sharing options...

1 fast z Posted January 19, 2009 Share Posted January 19, 2009 The stock numbers look exaclty like what my flow bench says for the same heads. I would of thought he could of got some more flow for the port job though. 230 cfm at .550 lift is achievable with stock size 44 mm intake valves.

Tony D Posted January 19, 2009 Share Posted January 19, 2009 The question for me is: "Where did you get those stainless steel injector clip bungs for the rail?" Quote Link to comment Share on other sites More sharing options...

Tony D Posted January 20, 2009 Share Posted January 20, 2009 Oooh, been looking for those! Oneset of 8 on the way to me now from Summitt Racing for only $129. Pricey, but not that much. I wanted the SS versions for a project I had in mind, but didn't know anybody made them. The other mounts on that page may come in handy for my SU project. May order one or two for that testing as well... Thanks for the link. Quote Link to comment Share on other sites More sharing options...
