my car had 23k on the ticker when i bought it but she will get pampered when i get it back till warantee is up and only helpful upgrades like possible cat removal and zaust, header and intake but only things to make it breathe better

Racing Beat says:
" - Over 2000 miles, full throttle and high RPM is acceptable."

My question is not why do people think they shoud drive differently for the break-in period, but why do people think that a 9000rpm redline car should really be driven below 5k?

I don't personally think keeping the revs low is pampering. On this engine driving below 3k is lugging IMO. The carbon build up problems appear to be caused by habitual low-rev driving, according to all the reports I've read.

I agree, after the break-in period is over, it's ok and even recommended to keep it over 3k, most definitely when using any amount of throttle, like to accelerate or go up a hill. Occasional excursions in the high rev range are good to keep it clear of carbon build-up (you should have a gut feel for when it needs this). I don't personally think that redlining it a whole lot is good for good longevity - I highly doubt that actually. I also hardly ever take it very high up there, nor use 100% throttle in first gear either - things happen too fast and too harshly in first gear for me and especially if I have any passengers. Again, that's just my personal taste in driving style.

Im sorry but thats b.s. Most 8's make that much to the wheel now after the flash unless u have an engine that is running too rich or just wasnt a quality motor.

ok welp i got car back today. new engine/flywheel/oil metering pump/ complete oil flush, new coolant, and ugh i think thats it

final problem was failed metering pump and dead rear rotor. they said oil was extremely sludgy???? i dunno what thats all about i just changed it lest than 2k before???? who knows maybe after breakin i'll go to royale purple i dunno why it sludged on me. oh well wish me better luck with this engine. i can' tseem to find the break in instructions so if someone wants to quick link go for it thanx guys

here is racing beat's guide http://www.racingbeat.com/RX8%20Break%20in.htm

just keep the revs spontaneous. don't keep it at a steady rate. go throughout the power band. do not wide open throttle. make sure you warm up the motor before driving off. you're doing all of this so everything seats in.

glad you got your car back!!!

Sounds like the sludging seems similar to oil coking in Turbos... do/did you make a habit of cooling down the engine before shutting off, esp. after hard driving and hot weather?? Did they ask you about that when they mentioned the oil sludge?

Racer X-8

My guess is that the sludge is just a whole bunch of finely ground-up engine. The quote here (from his other thread) sounds to me like his engine was working hard at that time at eating itself, chewing itself into fine dust, which makes sludge in oil. A "failed metering pump" equals no oil metering, which equals heavily accelerated rotor/chamber wear, hence a "dead rear rotor" for starters.

yeah. i am sorry for the mistype thing. but have you ever wondered. for example, just say the S2000 has around 240 bhp or 237. whatever, but the amount of whp they get is about 200 to 210. but what do we get. 180??. you have got to be kidding me if the engines in rx8s are around 237.

for the greddy turbos, yeah, substitue the greddy e manage will help. so that it shows Greddy doesn't know how the car work. otherwise, they will have a better e manage system.

then the mazda dealers. the engine's ability to redline at 9K is impressive. it feels like one of those INDI500 race cars. great. but wait, are rx8s equiped with the right tranny to handle the Revs. i don't think a Miata transmission will do good to the car.
