Is the OS .15 CV-R .. side or rear exhausted ??

Is my presumption correct? :

the .15 CV is side exhaust
and
the .15 CV-R is rear exhaust ??

can't find the specs on the OS website>>>

For 12 size engine only the TR series are rear exhaust, the CV series be it 12, 15 or the new 18 are all side exhaust, the R you are refering to are Recoil = Pull Start

Hey topgun, how did you decrease the crank case volume? Sounds like a good way to build up more pressure without having to alter the induction port.

My ittention odecreasing case volume was to increase vacuum and pressure level. But it doesn't mean we don't have to work on induction timing and duartion. case volume and timing realted to each other, but they do different things (we are talking about reasonble difference). I still made induction advanced to compare stock set up ( will like to go further, but not enough meet on shaft). Very important is when it is open and close and it is dictating engine power band and performance. I know a lot of people don't belive in more then 210 degree open on 12 engines, but I belive and do it,on my son's MR12 I have it open 215 and want to do 225, but again not enough meat. On my engine it is much more advanced.
But altering induction without altering the rest of the events will not change a lot, so whole chain of events has to be in siquence and right duration.
I just fill up ports on case with JB weld till the way I wanted to, after that mesured.

Default shims

my o.s. tr came with two shims, i use 20% fuel. If i remove one of the shims will that give the motor more power?or should i just run 30% fuel since the motor has two shims in it?
thanks

Ok just to clarify OS's naming convention:

CV engines .. the original SIDE exhaust
CV-R .. the new SIDE exhaust (R= racing, more power etc)
X= pullstart
(P)= pilot shaft
T= OS's Turbo (use OS's turbo plugs)

cheers
Mark

I was looking at the TR(P) T (eesh, mouthfull). I've read they make a lot of low end grunt which is appealing to me for a sedan. I was taking a look at their (O.S.) pipes and came across the 1032 which I believe is their top end pipe. If I were to use this pipe would I loose the bottom end the motor naturally makes or would the powerband be widened?

Is the turbo legal to use and most tracks for normal weekend racing?
