Yeah but that is a OLD program.

Im trying to figure out why my head temps jumped up 50 deg on avg. This engine would run all day long at 240-250 . All of a sudden its running at 300+. The decel fuel cut would cool the heads at will, now no effect. The decel cut is working. It just wants to hover at 295-310. Thermostat is working. Oil temps do not even top 150 (dry sump 8qts.) HMMMM

Engine: 2276cc
fuel injected
intercooled
turbo

Mine says 300 on the low and 350 to 375 when running hard. I don't know what it means or if something is off. My AFR's are good. timing is 28. I need to push it up to 30 or 32 to test.

Yeah, I came across it at least 6 years ago.

Thanks for the reply!

Well, i guess i could say it was running exceptionally cool before and running normal temps now! what type of gauge are you running? I base mine on the cyl head temp from the ecu and an autometer dual channel gauge. both run within a couple degrees of each other. mine ran about 325-340 once on a 90 deg day with 90% humidity and the oil temp about 195-200 I was pushing it hard and on a 80 mile round trip ride. Its nice and cool out today ill have to go make some runs on the local deserted highway and see what happens.

Yeah that's the one. Gets you in the ball park.

Well I worked on the mounts for the inter cooler. I need to wire the fan back up and weld up the new pressure duct if it ever gets here. I mounted the new alki injection tank.


Does it remind you of something. Aluminum tanks are costing over 50$ for a small tank and over 100 for something over a quart. That is crazy. I then thought fire extinguisher. It is a tank. I striped the tank and repainted it. I removed the top parts that make it look like a fire Ex. I also strapped it down with a steel band, so no bozo will try to put a fire out with alki.

I unwrapped my header today, it's back from coating. The color is Grey Ice and good for 2000°. It is only suppost to radiate 70° with 1400° exhaust gas. I'll post a couple more when I get some good light to take a picture in.
