Books are great and they will get you started in the right direction but you will eventually have to experiment and apply the knowledge. My advice build a car and try different engine combinations you will learn way more then a generic book that is most likely written for piston vehicles can teach you. The world is full of lemmings that do what the next guy does. Here is the problem when you do the same thing that everyone else is doing and expect different results. Try to get creative and try new things. Take what you learned in the books and apply it and see what really happens. Most of the papers that you are reading that discuss VE on rotary motors cover the topic in NA form. Things change dramatically when you have one air pump feeding another.



Bobby's project is a good example everyone is saying "it won't spool up it won't make the power" etc etc but 99.9 percent of the people have not tried it themselves. Bobby I will now leave your thread alone https://www.nopistons.com/forums/pub...IR#>/smile.png



As for the porting on my car it is a standard oversized street port. I have actually torn it apart for the many non-believers when the dyno sheets and data logs weren't enough proof. I am not the only guy making this power on a street ported motor there are a few others and I'm sure they got there the same way, trial and error because unfortunatley last time I was in Borders theree were no books in the automotive section called "How to make 800rwhp on a 13b."



Hey that is a idea Crispeed want to help me write it?

last one



the dump tubes go right out of the subframe. The wastegates look awesome installed in the car, nice and tidy.



And yes i know that they are different colors...It was that or wait for them to restock...


Who cares about the different colors? I think it looks pretty cool that way...

You are absolutely right. Unfortunanetly I must have gotten it all wrong. My idea of just coping the next guy was to slap the next best turbo on the engine and hope for a miracle. I really believed the pudding is in the porting. Now I am all back to square again!!!!!



Still, if you take a stock port it would make 800 rwhp at 50 psi and 7000rpm, at least theoretically. We all assume that will be to much pressure for the engine to handle. So now efficiency of the mototr comes into play. You can't chase after HP just with a larger turbo. The engine won't hold up and your turbo is in massive surge most of his life...short life.



Now add some porting and your boost level to make 800 will drop significantly. Substitute some rpms (expensive) and your boost level will drop again.



Shoot, my engine is apart right now and I thought I was on the right track. Looks like I need to take it apart many times to catch up to you....or when is this book going to be published???? https://www.nopistons.com/forums/pub...1047683561.gif



And sorry for hijacking this threat (all related though, I think)

You shouldn't, looks bitchin'. https://www.nopistons.com/forums/pub...#>/biggrin.png Edit: I mean hell, if I were doing it, I'd go different colors on the BOVs too. Uniform things are very *yawn* to me, doing things different...now there's a way to live life. (Reason I chose rotary car.)
