The title is the question.
I know what to look for with water-cooled stuff. I have no experience with air-cooled stuff yet... What say you? Is there a normal range? A never exceed number? Anyone ever use 4 thermocouples? Was there any noticeable difference (#3 is of concern to me)? Thoughts, tips, any data would be greatly appreciated! |

Just dying to know.
Delta across the CHT sensors? Did you see any evidence of any cylinder being significantly different than the others? Did the car have the racoon sized tube from the front during these tests? I'm guessing that was the biggest improvement to the cooling system you did. Ever ingest anything? |

QUOTE(technicalninja @ Jan 8 2024, 05:23 PM)  Just dying to know. Delta across the CHT sensors? Within 25F most of the time. QUOTE Did you see any evidence of any cylinder being significantly different than the others? Not really, although before I installed turning vanes under my shroud, I saw lower temps at cyls 2 & 3. QUOTE Did the car have the racoon sized tube from the front during these tests? That was only added in 2005 after being unable to keep the 12:1 engine CHTs below 400F on WOT runs. I implemented lots of air management ideas, but nothing solved the problem until I added forced air to the engine compartment. It didn't affect the temperature spread across cylinders. QUOTE I'm guessing that was the biggest improvement to the cooling system you did. Considering the side benefit of more air for induction, yes. QUOTE Ever ingest anything? There's a screen on the inlet at the front of the car. Lots of rubber tire bits collected there but nothing more substantial. |
