For those who couldn't care less how their 356 left the factory!

Hey Karl, yes I've seen these filters but I'm so restricted on height especially where the back two chokes sit and the engine lid comes down on them. I have a pal who runs the Jenvey injection set up, although it is on a 911, he has individual filters that just snap individually on the top of the ram pipes. I reckon the actual filtration isn't that good but it's got to be better than F all.

Graham, if you don't find another solution you could speak to ITG, as I know they do custom fits also.
They may be able to provide exactly what you need?
Could be worth a chat with them.

So tomorrow I shall be driving down to Piddlehinton to pick up my engine case. Yes, a lovely name for a little village down in deepest Dorset. Here resides my machine man and the reason he has the case again is that when we installed the crank we felt the tiniest resistance which was barely 5 degrees out of 360 but this was not perfect so the motor had to be torn down for a couple of light passes with the line bore weapon. There was something else we found and this was the bottom skirt of the piston hitting the lower part of the engine case. This does sound diabolicaly serious but it was just a simple error between me and the machine man. Whilst I gave him the piston and barrel which was 92 mil for a 2.8 litre engine, he had set up the depth for the boring bar for the usual 90 mil 2.7 engines. But the 92 has just a tad more stroke so a few more thou clearance was required. When I was speaking with the Mahle rep in Germany he did mention that the 92 piston being a RS item was a lot different to the run of the mill 90 and I simply forgot to pass this info to Stuart the machinist. This is no problem apart from putting the engine build back a couple of weeks.
With some 356 downtime on my hands I thouight I should try something that had been in the back of my mind for sometime. It's just a handling problem I thought I may be able to resolve. When I'm giving the Wee Beastie some serious beans into a corner, that means I'm overdriving the car, the front of the car picks up almost as if it's starting to oversteer. Because the rear of the car is fairly stiff with Koni coil overs and no torsion bars, the front feels very loose. One day when I've got a bunch of spare cash and time I shall chop out all the stock front suspension and fit in either a 911 set up or a four bar arrangement both, joyfully with rack and pinion steering but for now I thought a first step could be to stiffen the anti roll bar, I think you call it a sway bar. The stock size is 15mil but you can buy a 16 and a 17.5 'sport'. Only problem, they are the best part of 500 pounds which seems, like a load of Porsche stuff, excessive. So I reckon I should knock a bar up myself and keep the costs down. What I did was something that I had quite a few years ago on my clubsport 1650 Lotus 105E Anglia and this was an additional bar hung off the existing one. As I said, deadly cheap and quite quick to make. I used a length of 10mil bar and block of alluminium. I chopped the alloy into four on my bandsaw then drilled the bars slightly undersize so they would clamp well. Then sliced the 4 alloy blocks, I had to hacksaw these as they were too small for the band saw, then drilled and tapped them 8mil, heated and bent the bar, bit of paint and job done.
Obviously, I can't tell you if this works or not, well not yet anyway, but I can easily go for a larger size bar if I feel I am going in the right direction to cure my handling woes.

Got the cases back and the guys did a perfect job with the additional machining requirements that were needed. The bottom end is all bolted up but now there is further problem with the estimated compression ratio. We can't move the barrels up by using a larger base gasket, not that we want to because the 92mil barrels are not O ringed, as this tightens up the cam chains and they are on max as it is. The heads are finished and cc'd to .01 of a cc so I really don't want to start mucking around with them. The final figure for them is 63.7cc but the pistons are designed for a head volume of 68cc. As it stands this gives a comp ratio of approx 11.3 to 1 so I don't think I shall be strapping the twin turbos on just yet. Jokes over, what we are doing now is fly cutting the valve reliefs on the pistons. We shall cc the tops after this has been completed, and the amount that will be shaved will be something of a guess-timation because you are not dealing with a full circle just a half round on the top of the piston. With the cc figure we shall calculate how much we can shave off the top of the piston to effectively give us a comp ratio of approx 101/2 to 1. When this lot has been done and when it goes on the dyno, I hope there will be no pre ignition. I have only got a stock T distributor but I might get a better curve with a S dibby, we shall see.
And O.M.G. there is only one month to go before Portugal. I'm trying not to panic, the rest of the car is sorted, I've even got hold of a suit carrier for my DJ. I did get one tip which I'm sure is very useful. Follolwing a full gearbox rebuild, which my 915 has been, in order to fully lubricate all nooks and crannies, bearings and gears and anything else lurking within the gearbox internals, you should upend the box, best do this with a hoist, turn it all sides, up down, left, right so on the first drive every part has a good layer of EP. Bit basic but sort of makes sense, eh.
