simple cleaning with vineger or club soda but some good stuff on that site
so what kinda back pressure to boost ratio do you get with those headers? with what housing/turbo?
also have you found a real tuning use for the one egt gauge? ive always been under the assumption that a W/B is used for actual a/f ratio and then you use egt's on each primary for individual cylinder correction( for removing lean/ rich cylinders)?
In the studying I did when I was first putting together my engine configuration, I spent a lot of time looking at the high end turbo motorsports classes. Especially F1. Studying the F1 turbo era, I found that tuned length headers were very popular. In fact, I noticed that the era started out with more log style manifolds and evolved into tuned length. Now, these people have R&D resources at their disposal that I can't even begin to imagine. I would not dare to second guess their decisions to use tuned length headers. If they found there was power in that decision, then I was on the band wagon too. Another well known tuner, Steve Kinsler of Kinsler Fuel Injection has documented that a turbocharged engine reacts to cam and manifold tuning much the same way a naturally aspirated engine does. His quote on cam selection for a turbocharged engine is, "Don't choke that engine". Again, who am I to second guess his successful experiences. A lot of times you don't need to go through the expense to do your own testing to find answers to some tuning questions. Just look at what other highly successful people have done. And people that have much more resources for testing than a simple hobbiest racer.Nice work, especially in the merge area of the crossover.
Have you ever found any data that supports the idea that stepped, equal length headers are a benefit in a turbo application? With the backpressure I have thought there would be no or very little benefit.
CharlieF1. I'm glad you're getting something out of all this.Once again Donnie, you get me thinking. Your work is amazing and if I get to the point you're at I'd be a happy man.
