Another delta question????

I understand the whole delta process. Get the ECT up to 190 at 65 mph on the flat highway and check out the EOT. It should be under 15 degress. But my question is what role do different gears do to this delta. I have 4.30 gears instead of the 3.73 that came with the truck. Does this cause the EOT to be higher than normal.

I'm just curious. Current ECT 190-194 EOT are 198-200. I think that my deltas are fine right now just my brain spinning.

Basically you want to get on the highway and run under 2000 rpm. Its not your speed but how your engine is working. The test sees if the cooler is cooling.

The surrent TSB states to carefully accelerate to WOT to achieve maximum boost for the test. The engine needs to be up to temp also (coolant at 190 or higher).

That's so your temps get over 190*

So I guess that's what I mean. I always see the 65mph on flat highway, but my RPMs at 65 is different then the RPMs on the truck with stock gears. I guess its not that big of a deal.

I find overall MPH determines EOT. I'll lower EOT 5*+ if running at 50 MPH compared to 70+ MPH. I would guess RPMs play a part into the temps too.

Interesting... I was running down the highway today at 70 miles an hour and when my EOT got up to 190 my ECT was 187.

That's good, right?
