2500 Engine Red Line
Discussion
Hi,
Does anyone know what the red line is supposed to be for a standard 2500 engine? I had previously thought it was 5,500 rpm but recently saw an Autocar road test of a 2500S, where they state it is 5,800 rpm. The 1968 Autocar road test of the TR5 suggests the red line is 5,500 but they took it to 6,000 for their performance tests.
Perhaps I'm being being cautious (and pedantic) but with the long stroke 2500 engine, could 6,000 rpm do some harm?

I owned a few 2500 saloons and I can tell you that the red line on the tachos was 5500 rpm, if that helps.
Frankly, the ordinary carby engine is running out of puff by then anyway.
If you've got hot cams, big valves and decent PI or big carbs then it's a different story.

Just spotted a 2500S rev counter on eBay.

It looks like the red line is about 5750.
