I've got Tom's ECU, fast road cam and fuel pressure regulator in my race 924S. 177bhp. Now plenty will say that's not that impressive but Tom will tell you they never saw more than 148bhp from any of the 944s they tested on the rolling road they used to use so it represents virtually 20% improvement and its a very driveable engine.

Michael (Talkwrench) sent me a photo from the workshop of the first few bits that have been blasted before some experimentation.
The engine holder thingummybob has arrived too so I really need to clear some time to get over and start taking the main block apart.

.Quick update on this as I'm over at the workshop again this morning for some engine tinkering.
I broke down the engine last week and organised all of the parts that are going to be fiddled with.
Delighted to see that the piston faces and bores are in great shape. I did have to clear out a bunch of munched up wheat from the chambers that I assume was from some particularly mad pot-holing mice.
Then I organised all of the bits I got in the pallet. The list goes on and on but there is some great stuff there for modifying.
This morning I'm hoping to break down the bottom end and remove all the ancillaries. Also have a look at the cam. I'll be replacing that with something gnarly but if it's in good shape I'll clean it up and stick it in the stores for the other road engine along with these pistons, rods etc.

I feel like a real mechanic today having done mechanicky stuff under the expert tutelage of Michael.
Stripped down the bottom end by removing both balance shafts, sump and auxiliaries.
We're going to delete the balance shafts but that's not as simple as first thought as they're fed with oil through the housings. This will mean permanently sealing those oil ways but Michael seemed pretty laissez faire about it so, you know, whatevs.
Michael was also surprised at the sheer damned size of the crank. I have to admit to even my amateur eyes it is quite a piece of kit. It'll be interesting to see just what can be shaved from it.
So far pretty much everything about this engine is spanking. I bought it as a '80,000 mile engine' and I can quite believe it. Everything important is looking tickety boo.
Lots and lots and lots of media blasting about to happen, plus I've got to go back and remove the ladder and crank (and presumably all the other engine bits like pistons and rods and stuff). Aiming to do that on Thursday morning so the bare bottom end can be blasted. Then the phoenix from the ashes will rise, mightier than ever. Probably.

I did a bit of reading around on this issue as I have disconnected the balance shafts on my 924 S race car. I came down in favour of the view that at the consistently higher revs of a race car it wasn't too much of a risk, and that's been proven so far (touch wood) over about 8-9 40 min races plus practices.
At lower revs maybe it's an issue as the lower revs tend to be less smooth?
