Is that the master link/throttle cable setup yours came with?

My view is, as long as you use the proper piston shape, you are ahead of the game on an 885 head. This was done because parts were in house ready to go aside from some balancing. That, he just dumped a ton of money in the car, and we discovered his expensive head was cracked, so that had to be replaced. Long story, I made a thread about it.

Once you go OVER an 84mm stroke with a 135mm rod length the wrist pin on a custom piston encroaches the lower oil control ring necessitating support rings. This creates an extra gap for oil to get by along with becoming a point of friction/wear during warmup. In short, power is gained but longevity decreases. Additionally that wear/blowby is exacerbated when using 2618 alloy pistons.
Going 3.0L and larger is fine on a race car or a very aggressive street car, it just will not last nearly as long as a proper 2.5-2.9L (when I say proper I mean NOT using ghetto-machined stock cast pistons or the use of 130mm rods). If you are shooting for high numbers and don't mind building a new engine in 50k then go big.
I've got a write up on it if you shoot me a PM (it's a word document). Since I don't work at IE IE anymore, I don't feel like a cheesy sales guy in saying this was the premise behind designing the IE/MahleMotorsport 2.9L street-stroker pistons.
Sorry Kameron, but to your regularly scheduled program. Great to see you back with an ITB setup.Last edited by SkiFree; 05-17-2016, 09:57 AM.

I dont mind at all, this is the kind information that should be shared and posted.
I need to get some distilled water, oil, and I'm wanting to try this kind of sync. tool but summit racing nor anywhere local seems to have one.
The newer rhd setup has huge vacuum lines for the supplied vacuum block setup so my motion pro sync tool would need huge adapters to work. The new vac line barbs are like fuel line sized now and the motion pro tool uses the smallest vac line.
