Are ceramic apex seals good?
Ceramic apex seals are the ultimate seals for racing engines. Now, not every racing engine is going to need these, they are expensive, and for the most part, they are worth it. They don’t break, they can handle high heat and the best part is how light and resilient they are.
How often do apex seals need to be replaced?
Those apex seals don’t tend to last long before they need replacing, either. Rebuilding a Wankel at 80,000-100,000 miles is typical, and earlier than most piston engine need such exhaustive work.
How long do carbon apex seals last?
The seals that can fail and not do much harm are the carbon seals. They do not work well with boost, can not be detonated even once, and will only last about 20,000 miles if you are good to it but they won’t kill your engine when they fail.
What are the apex seals?
The apex seal is the seal placed at the tip or “apex” of the device. The apex seal is the only moving part that comes in direct contact with the rotor housing. A damaged or faulty apex seal can cause a host of problems. So, here are some signs that the apex seal in a rotary engine powered vehicle may be bad.
Are rotary motors reliable?
Rotary engines are basically just as reliable as standard engines. While some early designs had seal problems, many other contemporary designs did not. The seal problems were solved eventually, and overall a rotary engine requires somewhat less maintenance than a regular engine.
How long do rotary engines last RX8?
How long will the RX-8 engine last? There are various answers and speculations as to how long a typical RENESIS engine can last for. Just like any other engine, taking the time to care for it properly will make it last longer than usual, however, that could mean 80,000 miles or less.
How much compression should a rotary engine have?
Continuous low cranking compression pulses strongly suggest the failure of at least two apex seal, corner seal and/or side seal sets. Note: Race engines (peripheral or bridge port) generally have a normal compression pressure of 90-120 PSI. All other parameters are the same.
Why did Ian ianetti stop making 3mm seals?
Ianetti(sp?) stopped making his 3mm seals b/c of too many problems with them, or rather the rotor housings. If either are machined even slightly less than perfect, it almost always results in another rebuild rather quickly. Stick with 2mm seals.

What is the best apex seal for rotary engines?
Iannetti Ceramic Apex Seals are the ultimate apex seal for any rotary engine. They are extremely strong, very light, and do not wear into the rotor housings the way a steel apex seal can.
What’s the difference between stock and ceramic apex seals?
Stock apex seals can overheat, and warp which is not a concern with the ceramic seals. The ceramic seals although not indestructable, can take a lot more detonation than stock seals. They can also stand up to a lot more boost/power output.
