Various questions...
Here's what I'm reading... please let me know if some of these seem terribly wrong.
Oil Temp: 100 C (max when moving) Oil Temp: 110-115 C (sitting in traffic) Oil Press: 70-80 PSI (start-up) Oil Press: 40 PSI (hot) H2O Temp: 85 C (max when moving) H2O Temp: 100-110++++ C (sitting in traffic) (This engine does NOT like to sit still.) Also, the shifter wants to "pop out" of 2nd and 4th gears. Is this a linkage adjustment problem? Which way do I turn the brake-bias adjusting rod (at the pedal) to move the bias towards the front brakes and off the rear? When viewing the brake pedal from the driver's seat, the front brake cylinder is on the left and the rear is on the right. And there's a pivoting rod between the two that passes through the brake pedal (standard Wilwood unit). Thanks as usual! Gotta go! Keith :) |
What is your cooling setup?
Radiator (aluminum? # of cores?) Fans (electric only, puller, pusher?) Shroud? The moving coolant temp seems right, the idling temp seems warm. What is your timing at idle in traffic? How bored out was your block, do you have a sonic mapping of the cylinders (thin spots transmitting heat)? Oil pressure seems in the right range, though again, more info: what sort of pump are you running? |
Oh wise one of the spreadsheet ;)
The oil temperature seems a bit high to me, but it may be the result of tight break-in clearances. What weight oil are you using? Heavier oil will tend to run hotter. To change brake bias, shift the pivot bearing toward the cylinder that you want more pressure at (prepositionally speaking). Also, remember to have the front master cylinder link set up longer than the link to the rear one, so that the balance bar will tend toward becoming even under braking. |
Hi Buddy,
If you want some good, detailed instructions on how to adjust your brake balance bar, go to the Wilwood Web site under Brake Pedal Assemblies, Balance Bar Assembly, Tech Tips. This site has the best explanation and diagrams on how to adjust your balance bar. http://www.wilwood.com/products/peda.../pedaltech.asp Hope to see your car on the road soon. |
Keith,
Your water temp sitting seems a touch high. I sat in 400 traffic for 10 minutes two weekends ago on my trip to Southern, with the fans, it never got higher than 95. Take it from me, start with a CHECK of THE TIMING!! Oil PSI hot--is that sitting? or moving? |
Keith,
My engine was also running hotter than I wanted when sitting still in traffic idling. It never over heated (eg. never exceeded 240), but 220 seemed too hot for a 160 thermostat. I flushed all the anti-freeze out and replaced it with water, a bottle of lubricant/antirust and a bottle of water wetter. It now never goes above 190 even when sitting in long lights in the 105 degree Florida heat and humidity. My car stays in an insulated, indirectly heated garage in the winter so I don't worry about it freezing. Water is a much better coolant than anti-freeze. |
Everyone seems to have hit on all of the questions. I would check the timing and fuel mixture. You may want to check the calibration of the temp gauges as well. The shifter sounds like an adjustment thing or the hole needs to be cut out a little more. Keep working and bring it down here.
