Re: OS TR12 Efra version
 

You mean the E-spec? YES it is considerably faster, even more so than OS claims. Fast enough your lap times will probably decrease!! LOL J/K. But very serious about the power.

Bottom line about engine break-in guys. I posted on this many pages back- you can search for the details, but a fresh engine DOES NOT need tank after tank of idle speed with a rich setting!! All you have to do is run the motor conservatively on the tune around the track the same way you would race- part throttle, sometimes WOT, etc. Just don't run but 2-4 minutes at a time. Let the motor cool then run it again. After 3-4 heat cycles start sneaking up on a good tune and roll.

HEAR this- idling these motors super rich over and over and over is killing the piston to cylinder wall seal!!! You are washing the freaking cylinder wall down with super rich settings!!

OS 12 R-Spec and E-Spec
 

Hey guys someone told me that the OS 12TR E Spec and R Spec have the same case as the 12TR (P) T????? Please give me your opinion so i cna prove him wrong :)

Re: Re: OS TR12 Efra version
 

thanks:D

Re: OS 12 R-Spec and E-Spec
 

Hope you didn't bet on it. OS part# 21451010 is the crankcase for all three.

I don't know of any OS engine with a stainless steel heat sink.

Re: Re: OS 12 R-Spec and E-Spec
 

Crap.... so that means the only diffrence between the (P) T and the E/R-Spec is the head and 3 port piston and cylinder.

I wonder if the E/R-Spec is as fast or faster than the (P) T :D :nod: there so hard to bloody find any suggested shops etc..

I spoke to an OS engine rep about pipe choices on the .12 TR. he recomended trying the os 1040 pipe with the 1000m manifold. I havent got around to it yet but worth a try to anyone looking for a good pipe combo.

any of these will do !:D

Do you mean this one? Its aluminum. A stainless steel one would be rather heavy.
