Engine Run in!

[Lynchy172]

Iv just fully rebuilt my track car engine and was wondering how many miles til anyone reckon they would run it in like i was thinkin bout 250 or so??

Maybe depending on the spec, main thing is don't let it labour as well as over rev and don't run at one constant speed, I'd do 100 have an oil and filter change and have a good look in the oil, then 250 more to be safe.

Who did the rebuild? can they advise best way to run in?

I built it myself i was just gonna drive it around without goin high up in the revs!!!

sound tanks man!

50 miles, lots of engine breaking and foot to the floor without exceeding ~4krpm, bed the rings in, change the oil and filter, job done. Give it death.

I get annoyed people who think they need to bed the engine in for 5000 miles.

about 2hours on mineral oil giving it lots of load and that'll do IMO

 

[Andyman]

I reckon you should stick with the 250 miles thing mate with load but not over reving

120 for 30 miles down the A1

Cool thanks what bhp do any ye reckon i get from the engine i built it was a williams block got it bored out to 2.1 with wossner high compression pistons,crank lightned and balanced and knife edged lightened flywheel,matched inlets and polished head with piper high lift cams and vernier pulleys,four branch manifold full exhaust system and then gonna get the ecu chipped to suit it any ideas??

 

[sideways danny]

all that on the engine and still the standard ecu? wasted

might get close to 200 if it's been done very well
