car porn! NSFG (not safe for the garage!) Is this a different engine than what's you have in your car now?

its actually the engine that was in my 928. After the conversion from Variocam, to regular cylinder heads and Simard cams, I sat on the project for years. In the course of my delay, a vendor came out with a new super duty street friendly clutch kit. I finally got it running last year, and lets just say that vendor's clutches are hard on engines, and not tested as well as they proclaim. 5 motors that I know of have been lunched by being guinea pigs for their "development" and I use that term as loosely as they claim their products to be "tested".

:hiding:

Also adding to the problem is that this clutch vendor got into yet another spat with another vendor who is a great friend. The clutch vendor decided to quit providing support for his kit because I was friends with the vendor he was pissed at. The company that makes some of the parts for the kit would not provide support because said vendor is not an authorized reseller for their products.

Looks amazing!
Just out of curiosity, which bore size and stroke will this engine have?

6.4 liters. 3.75 stroke and 4.095 bore. Static compression ratio of 11.4:1 Simard gun drilled billet cams intake .450 lift, 226 duration, exhaust .420 lift 220 duration LCA 110. heads have 968 intake valves (with INA Touareg lifters) and ported to 50mm round intake port for the 50mm ITB's. I'll be running it with a Link Thunder ecu, Injector Dynamics 750cc injectors & VAG COP for ignition.

Titanium connecting rods, that seems expensive. Nice shiny Scat stroker crankshaft. I have a couple of those lying around.
The Scat Chevy syndrome has been discussed at length where the connecting rod sits offset in the piston. How is it in this case, are the crower rods made to sit in the center of the piston?
In my case with Scat Chevy 6 inch steel rods I solved the problem by turning the connecting rods 180 degrees around.

PS What happened to Mike Simard? I heard he went bankrupt.

the rods were a custom one off made set of crower titanium rods & since they didn't have stock available they made mine for the same price as off the shelf. The engine, was originally designed around oliver Ti rods, and so I wanted to stick with that in mind. I ran off the shelf Oliver rods for 30K miles with no issues and no abnormal wear on the pistons or cylinder walls.

made some decent progress this weekend. Head gaskets came in so I was motivated to get out there and get some stuff done. I didn't get to the head gaskets as I wanted to get the timing belt tensioner and oil pump installed as well as some of the oil control bits for the sump.



This is the oil deflector setup from Kevin Johnson's crank scraper kit. The drains from the 5-8 cylinder head are aimed right at the spinning counterweights so I think these are a good addition. The 5-8 side of the block has all of the oil galleys in the way which is why Porsche didn't design the drains as they did on the 1-4 side.

this is the drain that is aimed at the counterweights.

Image

This is one of the deflectors that redirects the oil straight down instead of onto the spinning counterweights.

Image

I decided to not use the crank scraper portion of the kit because I had the crank polished and I I decided that the gains from the scraper would be minimal.

I did decide to use the sump divider and the trap doors which I think works really well.

Here are the pan mods to go along with the sump divider
