The Number One Reliability Mod for the Rotary Engine.

[RETed]

Just trying to think outside the box...

How about we just drill through the rotor housing and just add an extra coolant line?
I've seen this done to oiling systems on 13B's but not for the coolant system...
Adding an extra coolant line into the area would:
1) add more coolant if the system can handle it, and
2) create more turbulent flow due to the "cross flow"

I highly doubt temp is an issue at all, you only need to look at the body of the spark plug and the FACT that carbon so readily builds up there, any meaningful heat would mean no carbon would accumulate there, it is much more a sign of a mismatch of apex seal materials, after market "modifications" lol or springs used by some people where the apex seal starts to lift off the rotor housing well before the spark plug hole you see it on some engines you don't see it on others.

That area on the leading plug is very cold (look at the amount of carbon accumulated on the spark plugs for verification of that fact) much more so than on the trailing plugs which are shielded

It's just the apex seal decides to jump off the housing and this is exaggerated by crap tunes especially ones relying on methadone injection (borderline detonation machines) that are causing apex seals to bounce all over the place

You see many "precision" self called "shops" wont even use new rotors let alone rotor housings in their builds and they wonder why they get odd wear patterns on the pieces of garbage they self assemble and post all over the internet and theorize as to why they get fucked up wear patterns in engines, let alone how they tune them, or what temperatures they run at.... it laughable at best, disturbing at the least.

After Market apex seal after a few hours


Stock apex seal after thousand hours

People need to look up conduction, convection, & radiation. Do some basic experiments of you own "at home" you will see water flow is not your problem at all.

Apex seal materials, springs, and tuning + theology to certain rubbish set ups are the single biggest reliability issues in rotaries.

Use the right parts
Keep the "whole motor" cool
Keep the inside of it cool (correct tuning)

And you will not see these carbon wings lol, be it at 200bhp or 1200bhp on a 13B (all on stock std 13B-REW rotor housings)

Thanks Barry, now does this information hold true to the S4 and older housings as i "thought" the S4 and older housings had a bigger "gap" between the plugs?

The first picture appears to have the 5/6th port actuators as on an S4 N/A.

I'll see if I can dig up a pair of CLR housings that had been modified for extra cooling tubes added for more cooling in this area for his road racing cars. He really has a lot of good experience and ideas for keeping motors alive! Most of his engine and race cars see no less than 7k rpm for hours on end.

There is many different things I could rate as #1 mods before fucking around with this on the internet advice of others.

That's just me though.

Calling this #1 reliability mod is so off base its not even funny, not to make a point Barry but it just is.

Put in a proper cooling system
Put in a proper thermostat
Put in proper drive pulleys
Tune your car right
Run the right parts on a rebuild
Find a legitimate rebuilder (#1 best bit of advice)
Find a rebuilder who has a running car to show what he preaches lol
Run a proper ignition system
Tune the car correctly
If its turbocharged make sure its water injected (absolute #1 reliability mod)
Don't use after market apex seals (#2 reliability mod)
Don't go to BDC for anything (#1 reliability mod)
Don't read anthying written by Howard Coleman (#1 reliability mod)
Use the internet mostly for porn (#1 reliability mod)

I've never had "carbon wings" LOL like I stated, some do, you have to question why???? probably cause they don't do any of the other basics properly???? Mis diagnosis and false conclusions abound........ welcome to forum hypothesis

[t_g_farrell]

+1 on all the stuff Rice just stated.

Heres a pic of the RB solution. I know theres some engineering time behind
this as well.

What is the consensus of the effectiveness of this mod?

Huh?

I only ask because a trusted engine builder raves about them. Those and the Goopy.

Wouldn’t it be more appropriate in a technical section ie. not the lounge, for responses to include a source supporting an opinion. For instance the effects of cooling… flow vs. velocity.

RX200013B- I am not sure when the widening of the plug spacing took place. I am more familar with 3rd Gens. Maybe someone can enlighten us.

rxspeed7- I would love to see some of Carlos’ cooling modifications. He is one of our Rotary Intellects.

How about the Factory Racing Engines. Here is a picture of the R26B racing housing. "The Money is No Object” project. What do their housings look like? It looks similar to the one being proposed. Well I'll be darned!

BARRY,

Can you copy and post all the information(if you have time) that has been gone over on the "evil forum" forever ago. With all the real data, real tests, real results, real conclusions, real pictures, real sae papers ect ect.
