looking to swap from stock apex seals to 3mm apex seals, as i want to run high boost, my engine is already freshly rebuilt so would it be pointless and alot of to change the rotar seals?

also is there anywere that supply these seals?

thanks

 

They're not unbreakable like anything BUT they do take more punishment over 2mm. Most people only 3mm when the rotors can't be clearanced for 2mm anymore so they have them machined to 3mm.

Note: I was actually at 18 PSi but didn't realize it until some days later...

Yes most definantly make sure you have an accurate reading of your AFR (wideband) and you have a reliable boost gauge. I find analog ones aren't all that accurate many times (like VDO). With a rotary being temperamental about boost level, I would invest in an Electronic Boost gauge for an accurate reading.

 

YES! it is always about the tuning.
you can buy,build,make,cut,grind,machine,weld,andETC.
but it still is about the tuning.
get your seventh sense working, so will know,before hand, that the engine is reaching detonation point!
