Yesterday at Buttonwillow for our DE, the temperature was not all that hot, but I could only get in 2 laps at race speed before my CHT gauge started hollering at me. Here are the maximum values from yesterday:
Cyl #1 384 degrees Cyl #2 357 degrees Cyl #3 433 degrees Cyl #4 402 degrees I have the alarm set at 400 degrees, so each time it reached that temp, I backed off and let it cool down and finished each session with just a Sunday drive. Here's what I have: My engine is a 2270 built by Original Customs 2 40 DLRAs: 150 main jets 180 air correction jets 34 venturis 9164.2 emulsion tubes 75 idle jets 50 pump jets Both carbs are accurately sync'd and the a/f gauge shows between 13 - 14 all through the progression to WOT The timing is set to about 30 degrees I am running a stock cooling system with the thermostat and flaps working properly. I pulled engine tin to look for obstructions. None. I am running a Sebtrab 8 x 10 oil cooler but my temps are over 220 when pushing it hard. No fans. I am not sure where to go from here: alternate cooling, larger oil cooler, fans? Any suggestions would be appreciated. |
