Some times you can find them at the large chain book stores, but you can always get them from Amazon.

 

Thank you Rick and Rick for the replies. I like to hear what works for everyone, the books will talk about optimizing a system and I like to see how that is applied and what the gains are in the real world.

I'll check into some of those books, thanks.

 

+1 for the corky bell book

 

This is the only real problem I see with a log design single, however I think the log holds in more heat than a header design, and heat is energy.

 

Not always. Its the materials you use that can sometimes be more drastic on the heat itself. And, if you can direct heat instead of trapping it, then you using the heat more effectively. Also, you will find that inside a log type manifold where there are sharp turns, hot spots will form and become problems later down the road. There is also a big difference in the way the vehicle responds and drives.

Use 625 Inconel...problem solved!

 

Will the hot spots cause failure of the log manifold or un-even cylinder temperatures? Also, how would the cam choice be affected by using a log manifold vs. a tubular header?

 

It is obvious that all problems can be solved with money

 

Not if they are welded properly, we give a warranty with our kits against cracking and workmanship and so far in 2 years I have only seen 1 return. Cylinder temperatures are all different anyway, the log or header will not effect cylinder temps. But tune up, injectors flow, and timing sure will. The header(s) is after the cylinder.
WE have on order several data logging products to help our research into where is it hotter etc, how fast is the turbo turning, pressure points within an intake system. And for the just to know reason.

 

Au contraire mon frere!! All problems can be solved with money, just not all people can solve all problems!
