breaking in new engine.
Turbo Mini Forums

Done some digging on breaking in engine and cam / followers and there seems to be various methods, so thought i best ask or could you comment.

1. Fill with cheap mineral oil / prime oil system.

2. Start engine, keep revs at 2000 rpm (what AFR should i be looking for 12 -13:1) or may be weaker to prevent bore wash and rings not bedding in.

3. Run for 20 min keeping an eye on oil pressure / water temp and AFR.

4. Change oil and filter (would you now put in Millers CTV or continue to run cheap stuff).

5. Get car out on road and keep accelerating and slowing down in 3rd.

6. Get to rolling road and set up as 16 psi..........................

7. Drive it

Whats your thoughts,

MITP 2012 17.01 seconds 1/4 mile against "The Don"
MITP 2013 16.83 seconds 1/4 mile

i did my k-series run 20mins for cams ect, changed oil and drove hard for about an hour, changed oil done noting since runs sweet:0

-Rover 100 VVC #2 - track project

Searching is all you need on TurboMinis

Thats what i was thinking but would you still run cheap mineral oil for the hard run as you call it.

Wont be pushing the mini too hard as wont have been set up so will be a 3rd gear load and unload for a while then a 50 mile trip on the motorway to RR.

Good oil only once the cam is bedded in.

16psi? Puff.

Don't worry about what gear you're in. Just make sure you are accelerating and decelerating not cruising.

In the 13's at last!.. Just

fairly hard acceleration dont go too high on the revs to begin with, over run apparently helps clean the bores too
imo i usually bed the cam in and the rings on the same oil then straight on to the good stuff
i bedded mine in at santapod - and set my personal best too

16 PSI for now Andy, thats why i fitted a turbo box when i didnt need too.

what boost will the gaycharger produce ?

Cheers brett, have to get it out one night when roads are quite (until the mini wakes everyone up) lol

Start it up, hold it at 2k for 20mins, while checking oil pressure, any leaks etc. if all is good take it out and put moderate load on the engine. There's no point changing the filter and oil before putting load on the engine, as you'll only have to do it again after.

I always inspect the filter after the initial run up on load to check for anything unusual, any large chunks of metal in there then at least you have an early warning that something might be wrong before putting lots of miles on it!

Fresh oil, fresh filter and get some miles on it.

1/4mile in 13.2sec @ 111 terminal on 15psi

Gaycharger will be ran at it's full potential - 12psi. Your turbo is barely spinning at 16psi.

16 will be for general street use may be tempted to up it for MITP if its finished.

All I can add Lee is all above.

You've got to finish it first Andy

Very helpful info in here, will be running mine in this weekend.

Would a AFR of 12-13 be ok as Lee said above?

Perfect AFR for power is12.5:1 under full boost but anywhere. 11.5 to 12.5 is safe. under cruise part throttle you may use it a little higher say 13s

Make sure you run very low boost and at least a bdd carb needle until it is ran in and has been on the rollers.

nice i have gone with the bdd to start with.

Where in sheff/rotherham would you say to get it set up on the rollers?

What psi would you be looking at on the standard actuator on the GT1752 set at 1/2 hole pre-load?

about 4-7 psi iirc

5.5psi

next time I'm running my engine in on the dyno, operator said he can put the equivalent of 500 miles on the engine

Cheers Brett, that should be fine for breaking / running in.

Then its a simple job of raising the boost using the Gizmo boost contrller i got off John when its at the rollers.

you might as well just get an actuator that gives you 100% boost and use the gizmo to give you another 100% on top

Now thtats an idea

What actuator would give 16 PSI, which would fit a GT1752, cant be any bigger than the standard actuator size though.

gt20, straight fit 15psi 1mm pre load you may need an longer arm depending on your actuator mount
