I just got my car done. took me 6 months ;) "yeah i know im slow" I changed my rotor house and one rotor. Now the question is .... how do i breake it in? 500km with no boost" ? And after 500km push it up to 4500? Anyone know the drill?! Sorry my for my leet english :D:Hammer
When I got my car back from Pip, the rev limiter was sent to 4.5k rpm and boost was set to .5 bar.
I was overly cautious with warming the car up the first few time (and still am) and avoided boost as much as possible for the first 500miles. For the second 500 miles, which are almost finished, I\'ve let it boost and have driven it as normally as possible - although I still avoid WOT and I make sure I always warm up and cool down thoroughly.
I’m sure lots of people will tell you different things – but as long as you don’t do anything stupid I’m sure it will go just fine!

ill try.... its hard..... must push the pedal to the metal.... :[ thanx mate! I just forgot how many miles i needed to drive before i could push it
When I was running in the engine in my FC last year, I initially kept it under 3krpm and then slowly went up to about 4k over time. Obviously I tried to avoid WOT and and boost, but I also made sure that I didn\'t run the engine at constant rpm and with varying loads - basically I staid off the motorway as much as possible for the first 1000 miles.
You must resist :p For your engines sake!!
I did 1000 miles at varying RPMS and loads on the motorways. Change gears alot, even when you dont need to. TRy and keep it under 4000 revs and keep off boost.
I ran mine in gently (no more than 3000rpm and no boost) for 500 miles, then got it mapped! :eek :D

You mapped it just after 500 miles? Stock turbos and so on? How high boost and so on? :):burnout
Nope, single turbo! Street ported. :p
as most people have said, most uk specialists will say minmum of 1000 miles. 500miles below about 3-3500rpm, off boost, the next 500miles, up to 4500rpm tops, with a little boost, no more than about 0.4bar.
you must vary the revs though, all the time. no good sitting on a motorway, at 70mph, for a couple of hours. must go up to 80, down to 60 etc, every few minutes etc
Quote from: D1 WTFyou must not vary the revs though, all the time.
Don\'t you mean you
must vary the revs ;)
lol, *EDITED*.
was think about saying "you must not sit at same revs for long peroid of time".
obviously i started writing it to.
cheers, that could have been confusing advice
thanks mates!i think i will start breaking it in now.... summer tires and snow
Totally different approach but...
What about abusing it...as the car is going to be abused for its lifetime???
I think when I had mine re-built I had to do the first 500 miles under 3500 revs then then next 500 under 4500 revs. Oil change then with every hundred miles after that increasing the revs by 100. Took FOREVER.
This i must admit is my technique. Initial warm up at tickover shut down check levels 15min run check levels again then drive it like you stole it. Whilst it may not be right by the book it works for me may shorten the engine life by a fraction but how many engine live to a old age anyway?
Kevin
Drive it like you stole it!!!!!!!!!! Just drive it normally..........:rolleyes: :guinness

Not if you want to keep a warranty!

1000 miles!:2eek I use to run my race piston engines in on the track. In fact the last engine did about about 30 or 40 miles on the rolling road, then was setup for fueling, then given decent beans in one 15 minute practice session, then was raced. Mind you, it was stripped down every season (about 300-400 miles at most). A lot of this was due to the tolerances and way the engine was built (it raced the rest of the season very very well)
Carl, what is it like for getting a fresh rotary engine ready to race? Given the car can\'t be driven on the road at all. I have run engines in on trackdays before - although that alternates between boring (keeping revs low, etc) and hilarious (still going faster than a lot of other drivers with a \'running in, please pass\' sign in the back :D )
This rotary world is taking a lot of learning!
Mind you, 1000 miles isn\'t too bad. It was nearer 10,000 miles before the V8 in my road car stopped feeling tight and reved. Big old American pig iron!
So no one subscribes to the ***very controversial*** piston method describe in detail here:
http://www.mototuneusa.com/break_in_secrets.htm
It isn\'t drive it like you stole it, but it is making sure you get maximum compression as early as possible once everything is warm... Basically I beleive this method works for piston engines, as does a few motorcycle teams I know but the rotary is a different beast ;)
You\'d still want to get the seals matched to the housing ASAP right?
Ceramic seals take alot longer,say around 2000 miles before they really start to feel good.
Of course,it does very much depend on the type of mileage done too.

That\'s how I ran in the race engines. The most miles one ever did before being raced was about 100 miles, all quite hard and fast.
I also ran in the V8 in a similar way, and that has made more power on the rolling road than the factory figures, and other cars of the same type on the same day. Now heading for 50k miles in 2 years with no problems or oil consumption.
But the rotary is a very different beast. Yes?

Dont worry Carl was just asking cos after speaking to kev about it i didnt know...
Il follow whatever you say guv, as long as you dont limit my car to 98mph :Giggle
Rixio:wave
P.S will call you tmrw :)
My WGT warranty note says keep under 4000rpm and don\'t use full throttle for 500 miles, then gradually raise revs and throttle untill 1000 miles when it is then run in.

Pip put a limiter on mine to stop me going over 4.5k.. he must not trust me :(.....
..... how right he was! :3gears-lh

It really does work a treat on piston engines!
But rotaries... Now, as the inside of the housing is smooth to begin with AFAIK then the corner seals just need to flatten to that surface right?
Mines 700 miles since WGT rebuild, there was a boost leak so never got it above vacuum for 500. Fixed the boost which now peaks at 10psi (I\'m sure Pip said he\'d limited it to 6). I\'ve maintained RPM<4500rpm and never pushed more than 1/3 throttle.
Brief but regular low pressure boosts must be the way to go near the end to position the apex seals under some strain, they move in and out and waggle up and down too!
