If x mean 0 then probably yes. Didn't you run your last one in on the trailer John?

So...........back to this running in process what is the best way to go about it, how many miles, what revs, is a running in map needed?

This is the ffedback I got from my engine builder when I asked the same question

> Here is what I suggest for breakin, but of course always follow what

>your tuner says to do. THis is just what works best for me.

>

> First 300 miles, no boost no more than 4500rpms. Use non-synthetic oils

>of 10-30 weight. I use the cheapest oil I can find for the first round.

> Granny drive the car, and don't get on the highway and go for 300miles.

>That is not the right way to do it. The fueling needs to be pretty spot on,

>if not a little lean for this otherwise the rings will take forever to

>seat.

> AFter 300 miles, change oil/filter and put in non-synthetic again but

>use a decent brand. Now you don't want to run any more than 12-13psi boost

>and set your limiter to 6000rpms. Drive like this for 1200-1500miles.

>This is also where you will be working on your part throttle fueling. You

>should be able to get it dialed in within this mileage timeframe.

> If all is well after 1500 miles, change oil/filter again. Still no

>synthetics. Have the car dyno tuned and then immeadiately after, change

>the oil to full synthetic. Now your done. Every 5000 miles or so I usually

>do 3rd gear pulls from 1500rpms to redline and then leave it in gear and

>let the engine do the braking. I do this about 10-15 times. This just

>helps keep the rings fully seated and usually will also help keep the

>cylinders fairly clean of any buildup you might encounter

[RA Dunk]

OMG its going to take fecking months to run it in like that!!

[colin_ross]

Ok I should have read that first and not just copied/paste it.

I followed the routine but changed the miles

300 before the first change

another 300 before the second

last one at 1000.

Buy a magnetic sump plug as well if you don't have one. I can post up pics to show you what mine pulled out of a fresh engine.

[RA Dunk]

so in effect

300 before the first change (on the cheapest oil available, under 4K) on daily town driving, no motorways

another 300 before the second (slightly better oil still non-synthetic no more than 12-13PSI, under 6K)

last one at 1000. (Remap and yehaaaaaa)

did you get a map to run it in on Col? is this necessary?

I've heard of people getting a running in or "guesstimap" before but I never bothered. I only changed a few things between stages so didn't see the point.....bigger engine,bigger turbo,new fuel system etc

Have you got an afr or knocklink? If so watch what they're tellign you. As long as the fuelling is ok and there's no det you should be fine but an e-mail to your mapper should confirm this.

think the Simtec comes built in with knock detection, but will double check with andy

cheers

Who is building the engine ? Ask them how to run it in, their tolerances and the way they've Honed it will pretty much determine the runing in procedure

[fai17]

Running in procedure is still a quess to me.

I'm going to speak with my builder soon.....but 500 miles comes to mine.

Use Millers run in oil

500 miles

Keep below 1 bar and 5k with varied driving but don't hold it on boost for any lenght of time.

Then new filter and Millers CF 10/60 and a map from the Forrest variety

Yes, Simtec has knock detection but it cant reterd to a safer level when it detects it.

As for the run in most tuners give it 2 miles before seeing 1 bar of boost and 5000 rpm (for very short periods) and then a further 200miles

before hiting it with 2+ bar of boost for short periods

Have a read at this.
