I will be porting my housings in the next week and I was wondering what everyones preferred steet port config was. As you know there are a few different ways of steet porting. I am just planning on taking it as big as possible, any thoughts or suggestions/warnings. I will have access to PFS port templates I believe. I think Rays templates are pretty big from what I remember. Dragon I 'm sure you have some experience here right?

Go BIG!...and be careful not to nick the sides of the end/intermediate plates.

Yea that is the advice that Ray gave me today. I am a little hesitent to do it because If I **** up it's gonna cost me $300 or so. But you gotta crack a few eggs right?

There really isn't much to it. The only trick is just going slow as not to get in a rush and break throught the back side of the housing while grinding it out. A new housing will run you about $300 if you screw up. I'll get this thread rolling by Monday.

Ok I got an email from Rob at Pineapple racing earlier. I didn't think through everything I should have. I didn't think about boost creep. When I open up the ports for the exhaust it's gonna wanna creep up on me.I was thinking that a boost controller would simply cure this. It's not that simple apperently. So I am gonna need to port the wastegate to help keep the boost creep down. I may put in a restrictor pill as well. We'll see ho wit turns out. I did one exhaust port so far. The bits I got gummed up with alluminum quickly though and were not good for long. They were not carbide tipped. I got Ryans good digi camera now and I will get some pics tomorrow.

Also Rob informed me that you should be cautious how wide the ports get. The widerthey are you really risk the apex seal bowing into the port and breaking themselves.

ok, since nobody is replying to this i'm gonna ask a bunch of stupid questions, cuz i don't know much about all this milling and porting stuff. what does all of this do and how ? wait.. that was one question, but i'm curious. also, do these 3mm seals make your engine last longer? if so, why doesn't everyone do it? ok theres three

As long as someone broke the ice with stupid questions....Will this shorten the life of my engine, and is it appropriate for regular street driving? I don't mean is it legal, but will it run ok?

Make sure that you get carbide bits. Most rotary files will wear out pretty quickly when doing porting.
