What is the best APEX SEAL for the RX8 Renesis Engine - reliability, performance, OEM or Aftermarket

[@AnthonyHaywood]

Thanks for all the education on behalf of everyone thank you!

👍

I was literally just talking about this to my friend I have been searching for literal months for this information

[@Vipurs]

Awesome vids to watch durning my my lunch break, thanks Kyle I hope to see you driving in Jersey this year!

[@jupier324]

brother, the video is very good, but please fix the white noise on the microphone

Been having a good experince with my RA classic seals. Running a borg warner 64.5 sxe at 1bar

Do you have an opinion about the Citroën three piece apex seals, patent US3894820? People at Aixro said it are good in corners. And about Citroën pt US3705818, for rubbing surfaces coating? It seems there are experimental data Nikasil being better than hard Chrome, but finding someone resurfacing housings with nikasil is hard.

[@dgmdgm7271]

Thanks for the information. But from what I understand, if we put more resistant ceramic apexes, we will inevitably ruin the housing more quickly... I don't know what is better... But it will certainly be more expensive.

[@KyleMohanRacing]

why would there be more resistance?

[@dgmdgm7271]

​@@KyleMohanRacing I think it's a bit like brakes. You can use harder brake pads, but you will necessarily wear out the disc more quickly.

[@mokokawi]

I would imagine if it's got enough oil,it should be ok

[@KyleMohanRacing]

Yeah, as long as lubrication and fuel delivery are good, it should be fine. Just expensive. As long as you don't break them somehow it's a good seal. Although long term carbon buildup will still be an issue in an RX8

[@jtso7636]

What makes ceramics unsuitable for a non-turbo street car?

[@KyleMohanRacing]

price they are $2,300.00 ish per set.

[@neitjnf]

if you go with RX-7 height apexes in a Renesis, what can you do about the corner seal metal plug?

[@KyleMohanRacing]

Simply run an RX7 corner. Or we can get RX8 corners modified but added expenses without a big benefit. Lots of RX7 corner seal options.

[@ultimatejay]

What about Atkins seals?

[@RedLine_Renesis]

So, is it safe to assume ceramic seals will cause more wear on the housings for OEM street use?

[@jtso7636]

Ceramic seals are supposed to have lower friction than OEM. It seems like no one has used them in a mildly modified street car since they're about $1500 for 1 rotor, so there's probably little data on use in that situation.

[@KyleMohanRacing]

no, they will last a long time as a ceramic seal can if in proper conditions. but the rest of the motor still wears out at normal rate...

[@KyleMohanRacing]

@jtso7636 Actually we built a couple street cars with ceramic seals. (Expensive) but happy to do if requested. The issue was usually lack of maintenance. Or some external component Failing and damaging the motor anyway. So, the ceramic seal was just an expensive part to break. ... - We generally suggest that if you want $2300 and Apex seals. Then you should be putting every other part in the motor as new as well. Very few motors start with all new parts. There's for very few street motors. Start off with ceramic apex seals.
