TDI

This picture shows the engine fully assembled, with the ancilliaries and HKS/Rotrex supercharger, on the trolley on it's way to being reinstalled in the car.

This picure shows the engine mostly assembled, without the anciliaries etc.

This picture shows the cylinder block assembled with one cylinder head/camshaft assembly almost complete.

Here you can see the cylinder block partially assembled, showing the Cosworth piston crowns, Cosworth cylinder head studs and metal cylinder head gaskets.

These are the Cosworth/Carillo H section forged steel connecting rods fitted to the Cosworth pistons. Please note the design of the underside reinforcement of the pistons.

Here's a picture of a Cosworth low compression forged piston undergoing the balancing checking process. These are very strong and are ideally suited to engines with a supercharger or turbocharger. The piston skirts have a super slippery anti-scuff coating too

Please note that I will be away on business Wednesday 21st and Thursday 22nd June so please expect any email and PM's to be replied to on Friday. Sam and Jeremy will be available to answer and urgent queries by email and phone as per usual.

Hi Guys, I heard from Cosworth yesterday that they are developing an intake plenum for the 350Z. I don't have a release date yet, but I think it's very encouraging that Cosworth are continuing to take an interest in the VQ35

No, the engine was standard but is now being uprated with Cosworth internals . Sorry for any confusion

And here is what used to be a connecting rod

This supercharged engine suffered a catastrophic failure at an indicated 195 MPH in 6th gear with the techo needle bouncing off the rev limiter Pieces of the connecting rods are still spread over some Belgian tarmac I believe Here's what happens to the cylinder block when a connecting rod parts company.

NICKNAMES If Laura, Suzanne, Kate and Sarah go out for lunch, they will call each other Laura, Suzanne, Kate and Sarah. If Mike, Charlie, Dave and John go out, they will affectionately refer to each other as Fat Boy, Godzilla, Sh*t-Head and Four-eyes. EATING OUT When the bill arrives, Mike, Charlie, Dave and John will each throw in £20, even though it's only for £32.50. None of them will have anything smaller and none will actually admit they want change back. When the girls get their bill, out come the pocket calculators. MONEY A man will pay £2 for a £1 item he needs. A woman will pay £1 for a £2 item that she doesn't need but it's on sale. BATHROOMS A man has six items in his bathroom: toothbrush and toothpaste, shaving cream, razor, a bar of soap, and a towel from M&S. The average number of items in the typical woman's bathroom is 337. A man would not be able to identify more than 20 of these items. ARGUMENTS A woman has the last word in any argument. Anything a man says after that is the beginning of a new argument. CATS Women love cats. Men say they love cats, but when women aren't looking, men kick cats. FUTURE A woman worries about the future until she gets a husband. A man never worries about the future until he gets a wife. SUCCESS A successful man is one who makes more money than his wife can spend. A successful woman is one who can find such a man. MARRIAGE A woman marries a man expecting he will change, but he doesn't. A man marries a woman expecting that she won't change, but she does. DRESSING UP A woman will dress up to go shopping, water the plants, empty the bins, answer the phone, read a book, and get the post. A man will dress up for weddings and funerals. NATURAL Men wake up as good-looking as they went to bed. Women somehow deteriorate during the night. OFFSPRING Ah, children. A woman knows all about her children. She knows about dentist appointments and romances, best friends, favourite foods, secret fears and hopes and dreams. A man is vaguely aware of some short people living in the house. THOUGHT FOR THE DAY Any married man should forget his mistakes. There's no use in two people remembering the same thing. What a woman says: C'mon...This place is a mess. You and I need to clean. Your trousers are on the floor and you'll have no clothes if we don't do the laundry now. What a man hears: C'MON ... blah, blah, blah YOU AND I blah, blah, blah, blah, blah ON THE FLOOR blah, blah, blah, NO CLOTHES blah, blah, blah, blah, NOW.

We are very proud to have been chosen to distribute these parts by Cosworth

Oh I see. Headers are normally exhaust manifolds

Since we installed the Rototest dyno in our new test facilities, we have been approached by a number of other tuning companies to use our facilities themselves, either using our Cosworth trained Technician or doing the work themselves. We have decided to launch this as a formal facility to the industry and to "self tuners" who can rent the dyno cell on an hourly basis. I hope this is of interest

The American call it a "Header". It's the part between the cylinder head and catalytic converter. A well designed manifold (header) will have tuned lengths to aid cylinder scavenging, and will have optimised runner volumes (too small will create aflow restriction, and too large will loose port velocity). There is a big difference between good and bad manifolds

Hello, Just to let you know that the HKS high performance exhaust manifolds are avaiable now for £1157.38 including vat. We haven't tested any yet, but will do in due course. Please let me know if you have any interest. Thanks

I looks like Allan is quoting estimated flywheel figures, whereas our Certificate of Performance shows figures at the hubs. Mark

If it was my car I would be inclined to try it with the standard air box, as the one you have does have areas of concern over it's design (this will allow validation of the effectiveness of the plenum spacers and air box individually), then I would be looking to use better exhaust manifolds. Mark

We did calibrate the a/f below 4k, it is just that with n/a cars most power gains are realised in the mid and higher rpm's, and especially with Grahams car there were no gains to be had below 4k from tuning. The FCON SZ and V Pro are both "piggy back ecu"s althogh the V Pro can be also used as a stand alone (but is very rarely done). The ecu is in open loop at all rpm's when at full throttle (not just above 4k). We can also map the closed loop cycles if needed by introducing 02 simulators (but rarely need to do so). Regarding the air/fuel distribution of the plenum, if anything the front 2 cylinders run richer (not leaner) that the other 4 because they do not have as much air flow. After tuning, the a/f's were the same. Hope this helps

That's a great shame Graham - I am very sorry for your disappointment. We have no experience of the parts that you bought so are unable to advise you whether they are good, bad or indifferent, but without doubt they do not work in this combination on a car of your current specification. It may well be the case that they will work better if you had more efficient exhaust manifolds and de-cats, or it could be that they will never work better than they are now. Unfortunately there's only one way to find out, and that's by testing. Please let me know if I can be of any help

I hope I'm not contravening any protocol by this: We would like to offer club members a 10% discount on the SLD parts and the labour at Lakeside or Warrington. Would an Admin or Mod please contact me to agree this please? Thanks

I was wondering what your favourite Japanese orientated car magazine was,and why. Plese take a minute to poll. Thanks

If you haven't been sorted yet, TDi North can do it and is in Warrington if that's any good to you? Pauls number is 01920 289100. Hope that helps

Cosworth released some flow data yesterday of their big valve CNC ported cylinder heads. I have attached the air flow data test sheet for your information. As a person who was responsible for a considerable amount of head porting and flow bench testing, I can tell you that this is very impressive
