wouldn't you like to have the time and equipment to measure the heat paths?

QUOTE(sean_v8_914 @ Nov 23 2011, 09:29 AM)  wouldn't you like to have the time and equipment to measure the heat paths? If it really mattered. At 200HP and even beyond we cool engines with iron cylinders and stock cooling systems without any issues and CHT values COOLER than a stock 2.0 using the same cooling system. Above that output no one has the money to buy the engines; so it really doesn't matter. The crazy ones we do today are just done for fun and these days I am retaining all of those and not even trying to sell them. Its just away to blister the competitors balls. With the component quality degradation that we have seen in the last two years, it'll be impossible for us to continue building high quality engines at any sane price level after 2015, and it might even occur sooner than that. My data logging system can measure 32 CHT/OT channels and I have used it to measure CHT and CT on the same engine with 4 sensors on each cylinder. What I learned was critical to the development of engine combinations (that don't generate heat), but not so much critical to the development of cooling systems. |
