There's still no data to support that CSF IC is an actual upgrade. Could be legit or could be another snakeoil product? We shall see.

Hope they are effective at lowering AIT. I am going to try MoCool to mix with IC coolant to see if it helps at all. |

If it's better quality that stock and 28% larger each side then it should work well, but want to see evidence as to how well they actually perform before dropping $2,500 on a set. |

Thanks for the pictures, always interesting.
Whatever works for your engine shop I guess, but did they say why they numbered the cylinders the way they did? You match the piston to the hole, but it would confuse me not to have the cylinders be numbered the same as the BMW layout. Maybe there's more to it than I realize. |

Looking good. Appears to be another solid build of a "bulletproof" long block. Keep up the good work. Congrats.

More great pictures. Please stop posting the rod bearing journal on the crank. My stomach gets knotted up every time I see it!
Oh, those wrist pins on the Carrillo rods are massive! Did the shop mention how much heavier the piston/rod combo is from Carrillo? Well worth the extra weight though! |

I assume these are the same - is your build stock compression? |

I'm surprised. I imagine the stock wrist pin is tapered internally so the difference in weight isn't as much as it would appear. Maybe with the inherent strength of the forged piston they can take more mass out of it compared to a casting.

Even with those wrist pins the whole rotating assembly is lighter then stock. |

That's correct - helps more fuel get into the combustion chamber and run higher boost in addition to slight insurance on knock prevention. Note I also have full head-work done so top end is just plain nutzzz....

Do you know of anyone who did a full point lower compression? I remember when talking with Steve that he said he provided both options.
