I've got the My02 WRx...since the gearbox and front diff etc all work together, is it possible to use a friction reducer made for gearboxes?

 

Only if you want to waste your money

 

Already bought it for engine, but this stuff does gearbox too.

Don't suppose it's okay for the rear LSD though?

 

Quite scary that you are going to use an addative in an 02 car

Rob

 

Why's that Rob?

 

The best you can hope for is that it will not clog the pores in the oil filter (Teflon/PTFE), the worst is that it will dissolve your big end and crank bearings (parafin based).

If these products were any good, the big oil companies, who spend millions on research, would use them/sell them. Some are dangerous, most are just useless.

If you filled an old army style cooking pan up with engine oil and then poured Teflon granules into the oil, would it turn into a Teflon coated non stick pan?

 

Oh..er...

It's this Extralube ZX1 stuff...used in everything...diffs, coolant, fuel, gearbox, engine...not PTFE. Still not a good idea?

 

What about "Moly slip" (molybdenum disulphide)? It's a solid lubricant that would keep the drivetrain from immediately ceasing if a car dumped its oil. That used to be used in rallying, didn't it? Or, wasn't it any good?

 

AS

What is in it then?

 

MoS2 (Molybdenum DiSulphide) particles are typically 7 micron in diameter, the holes in the oil filter are 10 micron.

The problem with it is the S, the Sulphur. This attacks the soft bearing material to form Sulphates.

 

Pete, it's the Extralube ZX1 stuff.

Not sure how it works, but the instructions say it can be put in anything..inc coolant! Can even be used in auto boxes.

Quote from box 'virtually eliminates friction and wear'.

I know my mate turbo Ken has used this stuff on a classic and he's done a loads of hard miles, just wasn't sure re the LSD.

 

Then perhaps MoS2 worked well in context, 'cos the drivetrains of the rally cars didn't need to survive for the periods we expect road cars to live for.

I'm a physical scientist by training, so understand what you mean. However - what are you saying is reacting with the MoS2? Some element of the oil itself, or directly with the metal componentry?

 

Fatman

It was explained to me by a very eminent chemist as...

Either the molecules break down allowing the Mo molecules to bond to the engines internals, releasing the corrosive sulphur molecules, or they don't and the additive does nothing. Mostly they don't but as the MoS2 passes through the crank and big end bearings, the pressure and temp are high enough to break some bonds. Right where you don't want it to happen.

I'm not a chemist and am relaying what a very good one explained to me

 

TBH I had only heard of MoS2 being used in gearboxes - not in engines. I imagine that there's less heat generated in gearbox oil than there is in engine oil, so perhaps that breakdown process isn't so serious/likely.

I can believe that MoS2 would break down quite easily, MoS2 is a covalently bonded molecule (i.e. quite a weak bond). So perhaps use in an engine wouldn't be such a good idea!

I wonder if MoS2 is still used in gearboxes on rally cars?

 

If your rear diff is an LSD, unless it specifically states that it works with LSD's, DON"T USE.

 

AS, you know Turbo Ken then lol.

He seems to know his stuff about turbocharged cars. His impreza is impressive but, OMG have you been out in the cossie or 21turb!!!!

I used the ZX1 treatment on my UK97, upon recommendation of Ken (uses it in his 21turbo running 2 bar - and the engine has covered 197,000 miles), and also upon recommendation of another mate Mark who uses it in his trackday car (alpina 5 series) and all his other cars.



Iain

 

I've used ZX1 in my last three cars (Astra GTE, Clio Williams and my current STI Type-R) and never had a problem with it.

Craig.

 

Yes of course you can, it's called 'oil' !

Paul

 

I've just added it to mine for gearbox, coolant etc...gearbox feels smoother (but that might be due to slightly better quality oil - time and miles will confirm that).

Yeh Ian, I worked in the same building as turbo Ken...I know he recommends it big time. I think it's working...but I need another tub to add to engine. If his has done those miles, then surely it cannot cause the problems above - or it would fail (with Ken's tuning, it needs to be a strong engine!).

 

AS,

Fair play to him though, he does seem to get the results.

Have you done your 50 - 70 times yet? Ken was chatting to me about this on Sunday over a beer lol.



Iain

 

Ah, not yet. I told Ken it would be pants for my motor as he wanted 30-50 results (not even on boost in 3rd at that speed!).

I'll have a go sometime this week, subject to a decent clear road.

I hope turbo Ken didn't drive back home after that...I know what he's like with a few beers!!

 

LOL @ TK after a few beers.

Just jesting with the stop watch thing, Ken's been talking about it for months.

I think his cossie is something like 1.8 seconds

Do you ever get down to Cirencester? If so it would be good to see the 02 beast.



Iain

 

Never been there bloke...ever. Good place?

We'll have to sort something with turbo Ken sometime.

Tell him to hurry up and fit that TD05..

 

LOL

I've told him that if he doesn't fit it soon then it automatically becomes my property lol.

I'm interested to see how he gets on with the 05, as i too want to replace my 04 with a front entry 05

 

Knowing Ken, he'll get 3 bar out of it at 3000 revs, and all he'll of done is buy a new fish-tank T for £.50

You'll need to do the jets and pump too, but it's worth every penny (Penny in Ken's case, pounds for everyone else).

 

LOL, true about the fish tank spares , he cracks me up, but then again gets the result.

Yeah i've been telling him to uprate the fuel pump etc for ages - all he says is 'i cannay see the point man, its been ok for this amount of time like'

 

I'm sure he would do it subject to someone supplying it for a £1 including packaging!

He does get results...but then again, the coke can does amazing things don't ya think?

 

I have done most of the saftey mods (and a few more lol)

Uprated fuel pump
Rising rate fuel reg
de-cat & ported exhaust manifold
ported polished & knife edged throttle body and intercooler pipework
Samco intercooler pipework
Catch tank for crankcase breather & rocker cover breathers
My own design auto intercooler waterspray kit
Induction kit
HKS FCD
Dawes
AFR meter
det cans etc

Plus a few other bits and bobs that have forgotten lol

Next is the TD05 and FMIC i think

 

LOL true, true

 

You'll be laughing with the TD05 and FMIC. Get it done bloke (don't wait for turbo Ken as he'll move from his arm chair by early next year...maybe).

I've got the APS TMIC (as I didn't want to cut the front bumper till it wasn't a front bumper anymore), with cold air feeds all around it. I've made sure the cold air doesn't stop the flow through the IC...and now she runs cold all day long, even on the outside castings. Only time I have trouble is when the cars stuck in traffic for ages...but then, I wouldn't boot it anyway, as the coolant temp goes through the roof - got a temp gauge to let me know when I can floor it again.

Also got the auto waterspray (my own design too), works a treat.
