what can are engines handly (HP)
I don't know if any one can answer this but what can rotarys handle HP wise before blowning a hole in the rotor?
or snaping the e shaft?
or blowing apart the housings?
and can we try and give the limits for each series of motor (S4,S5,rew)

Zenki FC - 400hp
Kouki FC - 500hp
FD - 600hp
This is the rule of thumb I stick to.  The rotors and rotor housing don't fail.  It's the dowel mount bosses that crack or the water jacket groove fails.

Bringing one back from the dead...
I thought the only difference between the S4 and S5 blocks was internal. What else is different? Is it the dowels? Can S5 blocks run mechanical OMP (sic)?
Help before my engine goes away for a rebuild!

it depends who you choose to listen to.......
i know of a Series 5 motor making 830HP with no extra dowels, running 2mm seals.
there are a number of guys out there making 500HP on series 4 blocks with no troubles.
i personally believe that cracking plates is due to detonation at anything under 650ish HP weather it be S4/S5 or FD engine block.

Like I always do, I always estimate on the conservative side.  Hey, we can't all be supertuners, and I guarantee you're going to detonate at least once.  Hell, I'll admit that I detonated my engine more than I have wanted to - not sissy "popcorn" detonation but NASTY hammer-on-metal-pipe detonation over a dozen times!  My motor is still together, and I've torn it down and found no damage.  Granted, I'm not even close to a 400hp monster...

by any chance are the guys making 300HP who are crackingplates - do they run 3mm apex seals?
if the do, be they believe you NEED extra dowels to run over 15psi boost too - sounds like 95% of New Zealand rotary guys if ya ask me hahaha

the two locating DOWELS which hold the rotor housing in the right place in relation to the end and centre plates.
Some people believe that you need to add extra ones down the combustion side of the housing to prevent the housing from "walking" sideways when you are running upped boost, but testing from a number of places has shown this is due to detonation and not from running high boost
