Gawd, I know. The expense will make me cry, though having full control of the map would be a relief.

Nev got one on the shelf which is pre increase costs that are now in place if you want it. You know you want it mapped properly

Some of you may have heard on the grapevine that I was getting some new hub carriers/uprights machined up for Nipper last year, due to the excessive cost of equivalents from Elise Parts.

Unfortunately (and frighteningly) that company who make parts for Ford TA cars etc. failed to machine them and tried evading paying me back. The woeful story/thread naming and shaming them is here if anyone is interested.

 

I had hoped to get multiple sets machined up for other people on here who wanted to lower their ride height without affecting wishbone angles. Perhaps in due course I will find some other company, though at the moment I don't feel the urge really.

Gutted about this Nev and don't blame you for not jumping back in.

[Nev]

Someone has suggested that I make it clear that I was reverse engineering an ordinary OEM hub carrier (not an Elise Parts one) - in case there was any ambiguity.

Fully synth Sylkolene 15w50 I think Chris and have changed the oil at least 4 times. Twice whilst running in over the first 500 miles or so (with mineral) and then fully synth every 3500 miles or so after that. I've never run out (or low) even on the dipstick either. It's all a bit of a mystery, hopefully identifiable when then engine is opened up. I also extracted/tested the spring + plunger on the oil relief valve in the pump and that is fine too, no sign of scoring or sticking on the plunger. I did this to be sure it wasn't stuck closed (had heard of a few cases where this has happened) as it might have caused overwhelming oil pressure at high revs and when the oil was cold, which might explain the turbo 'seals'/shaft leaking. I have bought an oil pressure sender unit and gauge for installation after the oil restrictor to the turbo for when I put the engine back in. This will at least let me know what pressure the turbo is seeing.

 

It might be worth sending a bit of oil off for sample.  One of the two Europa race cars we have here has a propensity to absorb a fair bit of fuel into the oil which thins it down considerably.  We have been using the silkolene 15-50, now swapping out to Joe Gibbs to see if that works any better.

 

 

Just bypass the oil cooler, best way to remove fuel from the sump is to up the temperature of the oil - not much difference in fuel retention properties between oils, although ester based oils will be worse

Ugg, I've just been pottering in the garage this evening amongst the debris of my engine extraction and saw the bowl of oil I drained out of the car the other day (approx. 3500 miles old, perhaps 4000 miles). I stirred it up and sniffed it and then compared it to fresh oil in the can. The used oil certainly smelled a lot different, not distinctly of petrol but certainly different and stronger and perhaps more petrol like... I think I will attempt a home made viscosity test by pouring a set amount of each oil (used and unused) down a narrow funnel and time it. If there is a marked difference in time (ie the used oil is thinner and hence flows faster) I wonder if this would be considered as evidence to oil contamination? Is that a fair test? The car does get dreadful MPG, approx. 20 MPG just driving normally, so maybe it is overfueling.

 

No, that won't do anything because there are lots of competing effects - oils thin due to viscosity modifier shear, they thicken due to sooting and oxidation, and thin due to fuel dilution. Let me check how much oil I needed to measure fuel dilution and get back to you tomorrow.

Was the block bored under tension? As you tension the block the cylinders will change shape, so they will be out of round if they didn't tension them.

[Nev]

Fez, if I were to send you a sample of original oil and the drained oil out of the sump would you be able to test them some how please? That would be ace if you could, but I don't want to cause a bother. Mind you the drained oil has been sitting around with just a rag over the basin that it is in, exposed to the garage air (dunno if that will have an effect).

I have no idea TBH, is it normal practice to tension the block (lengthways?) while the machining takes place? Would you mind explaining why would this be necessary as I'm out of my depth here... possibly the compressive force of the head bolts clamping down and squeezing the block out sideways??

Ha ha jokes aside from what dealings ive had wiv mark BEWARE is a bit strong!
To me mark is a total asset to the cosworth scene wiv out dout an wiv out people like him investing tonnes ov his time/money/effort/enthusiasm to keep moving things forward wiv what he's doing down his work shop think the cosworth scene would be at a MASSIV loss wiv out him!!!!! People will b slating him for the way he runs his business but to me if i phoned mark up an said ime thinking ov making one ov ur products my self he's the type ov guy will giv u help/advice on how to do it 99% ov other firms would politely tell u to fcuk OFF are u takin the p*ss an slam the phone down!!!!!! Mark is a genuine enthusiast that's hear to help us all wiv his work that is 2nd to non!!!!! Most ov his work is all bespoke work that all takes time an some times he might be a bit lackadaisical wiv his times but wiv ALL cock up every now an then!!!!!!! Marks hear to help an share all his knowledge regardless wat every one says!!!!!! Plus marks extending/extended/new staff wiv new machinery at his work shop which will help him get work out on time AT LAST ha ha All this is only my opinion but ime hopeing people will b thinking the same thing

 

Bet his mum's very proud.

I am hoping that someone clever and with an engineering backgound like Dave Hardwick or John Welsh or maybe JohnTurbo would be able to make some lowered front uprights. I suspect several sets would sell. Approx 3cm lowered hub offset would be suitable in my estimation, with hardpoints for 2 types of brakes (OEM and AP) and hardpoints for the wishbones. Any takers... ?!

Just buy the EP ones!

Just buy the EP ones!

£1100 for 2 chunks of metal is beyond my budget. I know they take some effort to design and reverse engineer from the OEM units, and an hour or two of machine time, but that is too much for me. Many of our cars are only worth £6000 to £12000 now, so spending 15% of their value is hard to justify unless you are racing or somesuch. Also, based on the truly terrible postings by Simon Southam, I want to avoid Elise Parts. Geary, Ian and others are fine and professional to deal with, but "Scuffers" is losing them trade, certainly from me anyway and I suspect from others too if what I hear on the grapevine is true.

Absolutely agree.
