LOL!!!!! you got it. And with summer hours i'm out of work at 3!!!!!

 

She has a heartbeat!!

But hiccups at high rpm... they are troubleshooting it know argh!

 

You already took your new engine to high RPM?

thewird

 

no, the dealership is still testing / verifying the install

besides breaking in a rebuilt rotary doesnt take that long.

1 hour below 7k
1 hour below 8k
1 hour reaching up to 9k

then you are good to go, with an oil change shortly therafter.

 

they run the engine for ONE FULL HOUR at those RPMS????

 

Are they actually driving the car or on a dyno? Or are they just free reving it?

As an FYI, just copied from MazdaSpeed Motorsports site. Take it for what it's worth. (Sorry for the formatting of the table.)

Rotary Engine Break-in Procedures

A proper and careful break-in period for a newly rebuilt engine is extremely important. The break-in procedures listed on the following page may seem excessive. However, an engine that has been broken in properly will see more power across the engine's rpm range and longer service life than a comparable engine that has not. If using the old bearings, please note the difference in hours and mileage requirements for the break-in period.

When breaking in any engine (race or stock), use a low ash content, mineral-based racing oil (20W or 30W). After the break-in period, change to a mineral or synthetic racing oil (30W or 40W).
Race Engine Break-in Procedures

The information provided in this catalog is intended for use by individuals with some knowledge of rotary engine rebuilding. There are many experienced high-performance rotary engine rebuilders across the country. Please contact us for the locations of these shops.

Race Engine Break-In

Using a dynamometer for engine break-in is preferred. If you do not have access to a "Dyno," use the mileage break-in figures on the following table. The engine should first be run at idle for 30-45 minutes. During this time, be sure to check for leaks and keep an eye on the gauges. Ideally, for the first 100 miles (depending on use of new or used bearings), avoid operating the engine above 5000 rpm or under heavy load.

From 100-200 miles, gradually increase rpm, but never allow the engine to approach red line. Beyond 200 miles we recommend only short bursts of power approaching red line for 100 miles. At this point, change the break-in engine oil. The engine break-in period is now complete.


TIME & MILEAGE RECOMMENDATIONS
DYNO HOURS MILEAGE
RPM NEW BEARINGS OLD BEARINGS NEW BEARINGS OLD BEARINGS
1500 0.5 - - -
2000 0.5 0.5 - -
2500 0.5 - - -
3000 0.5 - - -
4000 1.0 0.5 - -
5000 1.0 0.5 60 -
6000 1.5 0.5 60 25
6500 1.5 0.5 - -
7000 - - 60 25
8000 - - 60 25
8500 - - 60 25
TOTAL 7.0 2.5 300 100


*Edit, to decipher a couple of so you can read it, if you have new bearings, and are using a dyno, Mazdaspeed recommends:

.5 of an hour at 1500rpm
.5 at 2000rpm
.5 at 2500rpm
.5 at 3000rpm
1 at 4000rpm
1 at 5000rpm
1.5 at 6000rpm
1.5 at 6500pm

On the road (also new bearing)
60 miles at 5000rpm
60 miles at 6000rpm
60 miles at 7000rpm
60 miles at 8000rpm
60 miles at 8500rpm

Adjusted downward significantly (the other columns) for "seasoned" bearings.

Take that for what it's worth. There are too many rotary break-in theory's to count...

 

Ahhhhh....... thats better SHE'S BACK!!!!!!

God i missed driving my car!!

She's purring like a kitten

 

YES! Nice! Must have seemed like it was forever! I know that when my Talon was in the shop for so long I was absolutely crazy. I hate driving my wife's Grand Am GT piece of sh*t. So when I decided to get another car as I could not wait anymore for my Talon ... that's when I got my 8. I never looked back. My Talon is working great now ... awesome car ... but pales by comparison!! I gave the car to my son for his graduation from college. He's very happy ... but you can bet ... I'm happier!!! Congratulations on getting your baby back!!!!!

 

Glad to hear she's back! Though it took some time to source the engine, you give me a lot of assurance that whenever the time comes for my renny to pop, it'll be ok Drive her hard!! (especially at the track )

 

First post...I followed Railton over here. Glad you've got yours back.

I've got an 07 GT with 9,000 km on it...picked it up Sept last year...brand-new believe it or not.

I wasn't committed to it...I seem to be the only one that finds the seat uncomfortable...and I was thinking about trading it in on something else.

Once I looked at the options, I simply couldn't beat the value. For a new Mustang GT, they wanted my car...and $19,000. Makes no sense.

Anyway, I'm not a prolific poster by any means...but I will attempt to contribute where I can.

 

Well here are some pictures of my engine on the floor (not too sure if this is the old one or the new one) Sorry about the shitty quality, the tech took them with his cell phone. If you look closely in the background of the 4th picture you can see the other 8 up on the hoist getting its new engine at the same time.

 

and one more

 

Great she's back...c ya at the track and see how she goes.

 

wow... mine went smoothly compared to yours

 

Wow! What sh*tty treatment!! I must say ... you documented and wrote your responses amazingly well!! Let us know what happens. Thank God I find out about all these tragic stories the easy way! Thank you RX-8 Club!!

 

Lol !!! I was reading this thread as I was reading up on engine replacements when I saw this last post by me. I think this post was supposed to go to Thumpers post about his crappy treatment from Ajax Mazda!! I bet I confised a lot of people here!
