having just rebuilt the engine, i am waiting till 1200miles to complete run in period (will have covered 850 miles by tomorrow).

at the 1200mile time, i was thinking of getting it set-up (apexi fuel/boost controllers etc) on a rolling road.

however, is it wise to subject the engine to the punishment of a rolling road at such a low milage?

thanks
ian

 

IMHO no, give it few more k.
Give it a chance to loosen up, save you going back for a re-map when it is loose.

 

my engine being run in on a bench dyno and then run uo max power soon afterwards.

This is apparently stndard practice and nothing tio be concerned about.

 

ukLegacy:

where are you getting your Apexis tuned? I have apexi's and am thinking of doing a few subtle engine mods so will need a retune

 

Depends on the tolerances when built. The tighter you built it, the more miles you should give it.
From memory, I think you did build it fairly loose, so probably wouldnt worry too much.

 

Adam, Stevie, thats reassuring then
bearings are standard subaru tolerances, pistons are cossie forged with 3 thou clearance. heads etc are the old ones.

feels really loose and zappy already.

done 870miles now

cheers

Eagle7, havent a clue yet mate, thats the trouble around here, no 4x4 rollers.
i know how to set the apexi's myself, but how many r/road operators do i dont know.

where did you have yours done last time?
