Okay with that but to get a usable braking force you need high revs so what about engine wear and does using the engine brake regulary over a long period of time eg. For 10 years with high revs harm my engine
Using the same set of brake pads for 10 years would harm your vehicle more. Lol.
When your engine breaking you shouldnt need it anywhere near redline. Usually its pretty effective even if youre only a few rpm higher than cruising speeds. I imagine there might be a bit more wear downshifting close to the redline, but if youre the kind of person downshifting like that youre probably also revving your car to redline anyway lol
My car engine brakes pretty well at 3-4k RPM, highway cruising is 3K and redline is 6-7k. So i dont see why there should be much more wear. Unless youre trying to race your car and accelerate and decelerate as fast as possible there wont be an issue. You obviously use it in conjunction with your brakes if you need to stop quick
I have 491K on my original engine and transmission, and always engine brake. Still running quite well, and that’s more mileage than most people will put on in a decade.
When u have a rotary engine, high revs are just some everyday thing lol
You forgot to add that you also get better lubrication from engine breaking and thus afterwards(especially if you had a long downhill trip, with properly warm oil and engine) you can feel the engine smoother. Nice vid as always tho!
I’m going to add to this that my Focus has 491K on the original engine and transmission, and I always engine brake. The difference is that I actually downshift to do so. I rarely use my actual brakes. I’ve never had a problem related to doing this. I’ll also point out that when I’m about to come off of a highway at high speeds, I’ll engine brake with downshifting to the point of almost touching redline.
Iff you adjust your engines speed with your accelerator-pedal and not with your clutch, everything should be fine when your engine is warm
Especially after a long motorway run when the brakes are cold, you don’t want to jump on them straight away as this is how you warp discs. Engine brake and a few dabs to get some heat, then start braking more heavily
I do something similar but I do not redline, I only try to mach the revs with the accelerator and I ended using the brakes for parking and for those ‘just in case’ scenarios
Just be careful you dont put the pistons through the bonnet.
I had the same thermostat issue in my E36. The way I saw it was that the fan and radiator were working more than they were asked to since there was no “additional heat from combustion” to cool.
Trucks have factory equipment for this. Its perfectly fine.
Trucks use an exhaust brake…which restricts the exhaust to build back pressure to slow the engine. Different operations principle all together.

Nice vid. I like to engine brake my dads a4 2.0 diesel with heel’n’toe. Is that good too?
with heel’n toe? that only means you break at the same time as you downshift and match the engine speed with the gearbox to not wear the clutch. so in short no but if you are already breaking why would you engine break at the same time? does not make much of a difference does it?
It doesnt harm it as long its not strong
Ofc engine braking is better closer to redline, but even then id say your motor wont have a lot of notable wear over time
My A3s DSG actually shifts down when going downhill to be able to use engine braking.
