Background I would be primarily concerned with the i-VTEC cam related mechanisms. I do not see that this engine is an interference engine. If it were an interference engine and you floated your valves, you would have more than likely had valve to piston contact and that would have immediate effect on your motor as well as your driving experience, you ...

It's very hard to say what damage, if any, will have occurred. All I can tell you is from my own personal experience. I once went from the red line in 3rd gear with a wide open throttle to 4th at approximately 90mph on a 1983 Golf and accidentally selected 2nd (and managed to get the clutch up). The instantaneous effect was that all of the dials gave ...

I run a supercharger on my race car and it will definitely affect the safe RPM limit of a motor, the red line, as it increases the stresses of the internal components, the factory settings do not account for additional speed equipment added after the car was manufactured. Any kind of problem with a normally aspirated motor are greatly increased on a ...

I don't have any empirical evidence for you, so this is mostly opinion. IMHO, a supercharger will not change a redline. The redline is a factor of the mechanical abilities of the engine (internal components), and has nothing to do with anything the supercharger does to it (basically adding hp). If you don't change anything internally on the engine (rods, ...

Seeing as it's my question, I've kept it in the back of my mind for a while. Without any hard evidence to back it up, I've come to a general conclusion that makes sense to me. Immediately releasing the gas and putting the clutch in, such that the engine would go from WOT under load to idle without load, could cause unburnt oil, which was vented into the ...

The fundamental premise of an internal combustion engine is "pressure". The event described will have created pressures within the engine, far beyond anything it was ever designed to contain. The impacts on the mechanicals (moving parts) are secondary. Therefore the reliability factor of the engine is now zero. A catastrophic failure can be anticipated ...

If the car continued to drive normally no damage occurred. Start it up right now with the hood open (it helps to hear noises you would normally would not). What if the cars feels weird? Damage to the engine is immediately obvious at startup. A common type of damage are bent valves. Which occur when the valves are not closed fast enough and they hit the ...
