A lot of people run their engines in on the dyno. Lots of manufactures throw there engines onto a engine dyno to test performance...

I know a guy that builds 600+hp motors.. and first thing he does is rev the tits off it lol.. said if it doesn't handle now.. it'll never handle.. i like his philosophy :P

Robk nailed it on the head - "..the engine needs to be pushed hard enough to force the rings outwards and utilise the honed cross-hatching on the cylinder walls to bed in the rings, before the cross-hatching has time to fully wear away smooth."

..this is not achieved by low load/throttle/RPM conditions.

Light those tyres up rob haha

Go read the running in thread.
How many bloody times does it need to be said - this thread isn't for running in debates.

@MRTurbo - sorry pal but you're wrong, go read the correct thread for reasons why.

Yeah let's leave the running-in discussion for that other thread, thanks!

BTW...the engine was finally started today! We had it idling a bit too

Initially my mech filled up the cooling system, and found a leak which he had to spend a while fixing. He broke a rusted bolt in the process and had to heli coil it and so on, but that seems OK now.
When we went to start it for the first time, we spent ages mucking around trying to get the injectors to work, before realising that it was probably because I have high impedance injectors (instead of the factory low impedance ones), but I still had the resistor pack there, so the overall resistance would have been too high for the injectors to open properly. We bridged the resistor pack and made a few adjustments to the settings in the Adaptronic ECU, and it started! In the mean time my mech was sorting out the cooling system, I'm not sure if he finished bleeding the air out or not.
This is only a very small step in getting it fully running properly, but it's a good start!

Congrats dude, good feeling hearing it for the first isn't it!

sooon soooon!!!!!

It sounded awesome indeed. I still have to lower the idle speed to something more sensible, which will sound even better with the cams, but I probably won't be able to go much lower than 1000 RPM with the cams I have.

mine idles at 1100 don't be too worried.
