i would drive it gentle off boost,dont let the engine labour.revs are better than labour. dont sit on motorway at the same continious revs. plenty of oil changes.

vary engine revs, use a little boost, 5-10 psi, this forces the rings into the bore to bed in...

dont be affraid to rev it, i used up to 5k on mine, but just be steady, build it up.....

500 change oil,500 change to proper oil and renew filter.


remember, its only the rings your running in, nothing else needs it...

this is a can of worms lolbut i would defo not do 1000 miles i would do 50 under as much load and then start adding boost

as above Pete, dont sit a constant revs as bores will glaze and it will smoke- then you will have to show it some throttle. Hope it runs well for you mate.

I ran myne in on mineral oil for about 400-500miles, first 5miles or so were easyish, changed the oil and filter straight away. then changed it every 100miles.
just followed this guide but with next to no boost at all!

Pete,

Do not let the engine labour.

So do car companys run all their performance cars engines in before they sell any cars?

Depends quite a lot on how it was honed and what ring pack material and tolerances are used.

Any reputable engine builder will be telling you quite clearly what he expects, so just ask him mate. Nobody on here i warrantying your engine are they, so who cares what we think?

Do it motocross bike style, rev the living shit out of it from the second you first start it!

what does labour mean? sorry for sounding dumb

i thought this but i drove a new work car and had a little ragging when i got it and it sound like shite after that so i dont think they do do they? or do they run it in for a bit on a dyno type thing and thne it gets chucked in a car?

Cheers for the replys guys...

labour is pulling up a hill in third gear @ 1100rpm and the engine juddering!!

as for my newest yb build i ran it for 10 mins at 3000 rpm to bed cams in then dropped the oil, drove to test station steady away then after 50 miles started giving it some boost, not a lot mind. At 200 miles i were reving to 5000rpm at 20 psi then at 300 miles she were getting full bag of boost to the red line. And i have a perfect running engine.
