Some really interesting posts in here, but.... if manufacturers make the engine parts just strong enough to leave a bit of safety margin, why aren't mapped cars going bang all over the place? RS tuning will put 40-50BHp and 60-100lb FT of torque extra on an R26 engine and it's extremely rare for anything to pop. We're talking a 20% increase in power and 30% extra torque. And why can engines from some manufacturers (the VAG group mainly) withstand massive power increases with standard internals?
From what I understand from whats been said : Some cars parts are made to a price point so they fail by design earlier. Other might not be , or use a rod / piston from another setup that has been around for a while , or used in multiple engines. Some VAGs also have chocolate rods .. Some
I'm not saying people shouldn't tune they're cars. They should definitely do it. I'm just throwing some light about why you can increase power and things like this. First thing I do when I buy a new car, i look what tuning can do for that car and i never had a car without tuning. From mild to radical. I don't think I can find info about R26 because pretty much all left the company or something since 12-14 years ago. Not even 250 I cannot really find easily. If you read my older posts, I just say that the power increase has to be in balance with how you use the car. If you thrash the car daily, stay with a mild tune and change as many parts to push the boundaries forward. If the car just sees a blast from time to time, then you can go to some nicer numbers. I just wanted people to help people be aware of what happens beyond the remap. S.
Good bit of reading that second post, not much anyone could add to that. I recall seeing something on TV where they were testing the Focus ST 2.5 turbo engine in a similar way to that mentioned. Ran it for something like the equivalent of 100,000 miles at almost maximum revs. Was crazy seeing this engine glowing on a test bench.
They will, Every new engine will be bench tested by the manufacturer, Thats just part of development A friend of mine works at Ford Dunton in the Engine Dyno and does just that, Tests them to destruction pretty much
Friend used to work for Honda f1, they did the same with the f1 motor but could start and run a test cycle on an engine in Japan using the UK system. They used to wait for one of the Japanese guys to doze off, then fire up the motor closest to him.
