i did search and i didnt find much ,it would be useful to have a  reference doc or subject  of some kind to know the reasonable   max rpm  to finish races (the redline)for all cars of all mods , i know the the Cosworth  limit was 9000rpm in 67 but in 68 -69 ?? in the game and in the GPLsetup theres the maximum power and torque rpm  but not the redline

Hi,

I think their may be a redline.

Just looked at a setup of mine in GPLsetup for the 69 extra Matra.

Shows a bold redline in the lower graph. If you follow an imaginary line upwards to the upper graph it appears to relate to a redline of 10,000 to 10,100 Max RPM.

Will look at some other car setups for other mods via GPLsetup and see if the cos worth Max RPM differs.

Hopefully I'm reading the graphs correctly.

Would be good to know. A list as you say would be really useful for all cars.

Paul.

Oops.

Guess I'm wrong.

Looked at a setup for a 67 Lotus 49.

Lower graph redline moved.. but up not down as expected to a lower max redline.

Actually realise now it relates to Max top speed in relation to gearing. Not revs.

Paul.

youre right , i dont trust that red line in in GPL setup , its incredible that a basic info like that is not somewhere, im sure that its possible to do simple chart

Ok.. I have seen this info regarding safe Max RPM's in at least the 67 cars.

It was in the tech data for the cars in another sim.

I'm trying to remember. May have been in Assetto Corsa or something.

If I find it will try to copy info and list it here.

Whether its correct or not is another matter.

But this info must be within the GPL  community somewhere as it must surely be basic data to have been able to build all the specific mods.

Paul.

It should be near the max power RPM, some 100-150 rpms over maybe. So the data is in the car info screen.

in the original 67 season  the max power of the Cosworth was at 9000 , and anybody who drove the lotus 67 knows that you were not finishing race if you were going over 9000 ,so i wouldnt rely too much on the numbers in the team and players info in the game

You can change gear with the lotus at 9000 or just 1 or 2 hundred revs more and it's fine as long as lift properly. I always took the peak power figures to be guidelines of "don't go much over this figure". You can kind of hear when you are thrashing the engine too much, it sounds painful.
I agree it would be helpful to know when engine damage starts for each car, but the values given in the player info screen aren't too bad indications.

There are more factors that come into play damaging the engine, like speedshifting and overheating. Or suffering chassis damage, it can trigger mechanical failures as well.

That said, a solid redline number for each 67 car would be handy. The red dots in GPLSM shows the redline, at the 90% powerband graphic. But it's a bit hard to read correctly. The Team Info only shows max BHP at a certain RPM, but that is clearly under the redline ofcourse, at least for most cars.

Depending on the engine characteristic, you can/have to use more revs, or less. For the BRM more, the Brabham less, for example.

PS: sometimes you don't redline at all, because the engine would overheat (for example Honda), or you would be slower (Brabham). All in all there's simply no basic guideline to keep the engine safe. Most of it you have to learn by practice an experience, by racing.
