Whats the diff between turboing a Rotary and a piston engine

[tifneedle208]

I'd figure there would be much less wear on a rotary. For some reason in my uneducated mind it just makes sense.

In a piston engine, if its not designed for the additional HP you get a lot more wear and less engine life at high boost. Including throwing a rod or blowing a hole in the block if you run it to high without the propper upgrades.

Now on a rotary, it works different. Wouldn't turboing a rotary with high boost cause less wear and less damage to the engine life than it would if you boosted a piston engine?

Blast...thought I was on to something there for a minute.

Turbo charged Rotary's especially with high boost have a bitch load of problems with them blowing up because they don't get enough fuel and they decide to blow seals and then blow up. It costs alot to get alot from a turbocharged rotary.

ratarys have enought trouble keeping cool, even worse if u slap a turbo on there. none the less its my favorite engine.

rotarys hate heat, and detonation, both of which turbos can easily cause, so if you turbo a rotary it has to be done right, you have to make sure the fuel and the cooling system is up to spec, and they are very thirsty, thats why you see alot of rotaries with massive injectors

another problem is alot of the aftermarket apex seals dont last as long as the stock weaker ones

but rotaries still kick ass

yeah, pretty much any engine u add boost to is going to have wear and reliablility problems. No matter how the engine is built, the added pressure will always increase the strain on the block and internals. Rotaries also arent very well known for being reliable either. The seals blow and are hard to replace.
