So while my 914-6 oil tanks are being machined I going to start working through my header with heat exhanger design out of stainless.. I do not have non compete on these with m&k so that gives me design freedom.. However I will use similar design process as the m&k/ rarlyl8 design. So my question is 1.5" the most common size or allot of you using 1.625

I actually think the idea of a heat plenum that would fit to the existing header choices to be a good idea. As you say, why reinvent the wheel. And all the folks out there with the Bursch headers (I think those are the most common after market ones out there) would have the option of adding heat to there existing headers for way less than an all new set.
I would also suggest looking at a very abbreviated design. My stock set with the "full metal jacket" treatment makes lots of heat.,, more than needed except maybe in the most extreme situations and who among us is out driving their sixes at zero degrees?? The aviation style "heat muffs" are much smaller ( https://www.aircraftspruce.com/pages/ep/car...rsheatmuffs.php ) and the single one in my plane makes a lot of heat. Besides price, the biggest benefit might be that a smaller, well engineered muff would allow for a lot more room to adjust valves. I have not attempted a valve adjustment with the stock HE's in place (is it even possible??) but was able to do one with Bursch headers in place. What say the masses (IMG:style_emoticons/default/confused24.gif) ?? |
