finer thread pitch= more clamping force= use less torque for same clamping force.

My guess this one is going to be quite a bit more aggressive? Will you be using the same Borg Warner twin scroll or are you going with a complete new set up?

Yes, I will use the same twin scroll 'small' Borg turbo I still have left from the old engine. The new engine will also be equipped with these newly developed billet heads from Thorsten Pieper. Should be done before years end |

I have heard from Thorsten's T4 head project a couple of months ago, but didn't want to spill the beans. It is top quality for sure just like the oxyboxer heads. I would think 500-550hp with the same reliability as your previous engine is really possible.

Congrats Walter.
Hay,I was looking at Pauters website,I noticed that he's making his rockers without needle bearings or bushings for shaft support; just aluminium rockers to shaft. I wonder why he has not stated why. This is a sharp turn from needle bearings, bushings, to nothing What is your choice for rods? How about cooling system, upright? Nice work Walter |

I already have the rods, they were a test set from R&R through Jake. Here coupled to a set of 77,50m pistons from the 1200T project (testfit for the 20mm pins): |

Those rods look plenty strong enough. |

Nice parts! What cylinders will you be using? Interesting that you chose to go to a 98mm bore, I would have thought that the heads were made for a minimum 100mm bore. I can understand wanting to minimize knock but 98 is somewhat exotic, hence the question on what cylinders you will use. It's good to see you back, always loved your projects and inspirates me to keep miy project going!

The yet-to-be-determined bore (98 or 100) is still up in the air, but best chance is indeed 98mm. Knock threshold isn't a consideration on that aspect, trust me. I am not convinced bore has that high a correlation with knock in our application anyways.
If it turns out to become 98mm bore, I'll tell the story behind why lateron |

My thoughts exactly. The 100cc difference of the 2mm bore will make only a very small difference in spool, so the better/stronger cylinder (and costs) will play a more important role
