/\ a little more actually . Bloody boost controllers are the devils work !

My guess, a loud noise, a push against the flat rotor face towards the stationary gear, if the stationary gear has enough wear for the apex to leave (or almost leave) the rotor housing, the apex breaks as the gases rush past the rotor/housing gap.,,,,


Just my guess.


:scratchhe

maybe ask yourself this ... did it detonate or did the flame front jump the apex seal surface into the following chamber(s)?

Currently at 17000 miles and the major detonation scare I had a few thousand miles back does not appear to have affected performance .
Also : now routinely running at 11-12psi in the lower rpm range .

I do get a feeling that my compression may be down a little due to the occasional hot start difficulty but this has been the case since the engine was rebuilt so I just put it down to using old housings .

Does your car has the most current starter? This might help with issue you have with hot start.

I parked my car for the winter so no mileage for the last 3 months....Currently I have about say 13000 miles or so on the rebuilt engine (esmeril seals) and on the 2nd turbo (precision 6265. The old one was the no name turbo that lasted almost 10K miles). And I do need a new starter. Mine crank real slows and take a long long crank to start the engine.

No it doesn't so you are probably right there . It isn't a big enough issue for me to warrant the expense ($700 here) of fitting one though.

That is spendy. My dealership charged me $379 installed.

even if I imported one I'd be lookin at around nz$500-600

Interesting data. Has anyone else experienced hard hot starts with new rotor housings with the Esmeril seals? Im very close to buying so im watching this thread like a hawk

Bump.

Any new info on how these are working? Anymore hot start issues?

Im needing a rebuild, staying NA, would like some NRS ceramic, but really cant afford them, thus looking into Esmeril.

Since last time I talked to you I ordered a new starter from BHR. I installed it myself which only took like 20 mins or so. It took longest to jack the car up. The replacement was easy and fast.

With new starter I don't have long start anymore. It starts almost immediately everytime. No more embrassment at gas station where I routeenly had to pop up the hood to pull fuse and restart engine. I tried start the engine back to back to back 5 times last night and it starts up on first tried every time. Life might be easier for you if you replace your old starter with a new one and it may eliminate the hot start issue that you have.

/\ good to hear . It's really not much of an issue for me though . It always starts - just takes a little longer than I would like .

22000 miles and still ok .

how have you been driving it, hard, mild or granny driving???

A mixture of all that . My daily driving is pretty sedate around town but i do regularly give it full noise through the rev range and that means 11psi which is not mucking around ...


Have not tracked the car with these seals yet though.

o ok hows your air\fuel looking crusing and on full boost.

Really good thanks , how about yours ?



Sorry - what are you getting at ?

welcome, mine is a little on the rich side but its good.

o sorry man i come in peace i was just wondering thats all.

Still all good at 30000 miles . Upgraded starter resolved hard starting mentioned earlier.

on a rotary a faster starter always does regardless of the apex seals

yes

bump

Nothing new here - what about you ?

I had the soda can crush sound twice with the EMU. Stock seals were fine when Charles did the rebuild (car had 47k miles or so at the time?).

Not sure we can compare the esmeral seals to stock just by saying the engine still runs after detonation.

Engine teardown with Esmeril apex seals at 60,000 kms.......
