215? is normal operating temps for these engines. Corvettes see upwards of 230? when on the track. Not sure what everyones worry about being at the temp. These's aren't SBC that need to be under 195?
It's one thing if the thermostat is keeping it that toasty, it's another if not enough airflow is doing it. That's not a controlled temp, it's a problem waiting to bite you in the ass.
But it doesn't explain everyones fear of running at stock temp for these engines. Whats the fear?
That's a different topic, but it's some more headroom for temp buildup when you get into some boostyness.
I agree that they dont need to run at 190. My concern is that if I cannot keep the temps in check just cruising around town there is no way I will be able to be able to keep it cool on track for a 20 minute session. Last year I saw temps up close to 230. I increased boost levels and am afraid I dont have enough cooling for sustained track days even with the 3 core radiator.
From what I have read, the reasoning for the high temps has everything to do with emissions output and nothing to do with ideal operating temps.
I am not sure Ill take the car out for another track day though so its probably not even worth me worrying about at this point.
Find NWAA events on MSR. They keep the number of entrants low and you will get so much seat time you will be sitting on the sidelines watching, saving your tires. BCA does the same thing occasionally. I ran with them last year at an event that was limited to 25-30 drivers. I think I made 20+ runs that day. At the BCA hosted Audi event at PIR I made 30+ runs and put the car away because the front tires were done. That event finished them off.
I love the sound of that Roy. Ill look them up. I have a set of 315 rivals I need to finish off. I might throw them on for this weekend if I go. I like the 11" wheels better than the 10's so I want to swap on some fresh rubber on them. Have one set with Rivals and another with the yok's
Sean, to better guide that belt, maybe add one or two idlers with flanges to help pick up any sudden slack, keep vibration and wander down?
If it is 6 rib, maybe try a Gates 36270 (https://www.rockauto.com/en/moreinfo.php?pk=1390705&jsn=2055). Here's a massive list of them http://www.gates.com/oreilly/PDFs/Pulley Size Listing.pdf . Same 6-rib pulley but with ribs: Gates 36100 (https://www.rockauto.com/en/moreinfo.php?pk=1015482&jsn=2059)
HTH
I have never seen those smooth back with flanges before. If I have other issues with the belt coming off I will definately give those a shot. How did you find those? Are they a normal application on something?
