engine break in period
Have a single turbo installation at hand with a rebuilt motor. Should i start off with stock twins or should i slap on the single for the break in period and hope that I have enough control over myself for the break in period????

Probably best not to do the work twice and just install the single turbo. Then in your EMS, set up overboost fuel cut for about 2PSI to keep you from using the out of control foot.

thanx!! what is a decent break in period? 3k? 5k??

*Pre-mix. Even with an OMP I'd do about .5 oz. per gallon. *For initial start-up pull the EGI and crank it for 30 seconds or so until you build up some oil pressure. Replace the EGI and start it up. If everything is normal (no obvious leaks, funny noises or whatever) Monitor temps closely. Let it idle at least until at full operating temperature. Good time to check to make sure fans come on at all speeds. *No boost for 500 miles. Then change oil and filter. *Reduced boost for another 500 miles. IIRC, a trusted builder and board member suggests keeping it under ~ 5 psi. Change oil and filter again. *Full boost for another 500 miles but change oil and filter again. Break-in complete. There is some debate on the worth of breaking an engine in. I'm not a guru, but in the camp that it's the thing to do. I think it also depends on exactly what was rebuilt, i.e. did it include main and rotor bearings? I think heat cycles are also important. So don't just go out and drive 500 miles down the interstate. Normal driving, with normal loads and normal changes and ranges in rpm. I would go ahead and install the single turbo. Obviously with all the changes I would NOT use synthetic for break-in. And if you have a good set of USED plugs, consider using them for intial start-up. Save the new plugs for AFTER all the hylomar, anti-seize and assembly lube has burned off. My .02. |
I was wondering the same this as well

Everyone has a different opinion on breaking. Personally I drive easily for the first 500 miles or so, change the oil, then beat the hell out of it.
