Well she's back together and running now , had the engine back off Fred Friday afternoon , was away in Castle Coombe Saturday so didn't have chance to work on it , did plan on coming in Sunday but after being in a neighbors house till 4am for a birthday party I suffered most of sunday with a...

Had mine since may and loving it , what a bonkers car ! Changed the wheels and tyres on mine to mpss and BC 2 piece , tyres are as good as the original bridgestones. i have also fitted a Russ fellows system but without the dp's , sounds awesome ! mine is stage 1 and goes well , I can't...

The box is about 9k euro's , as far as I can tell it comes with the bellhousing to fit on the clio engine , if they mean the 197 block then as the sodemo engine needs a new block i'll see if the head will fit one and i'll use a 197 block , i'm still half tempted to build the 197 road car into a...

Just to add i'll be selling my sadev in the next 6 weeks , it has the lower CW&P for rallying , and has just had a brand new barrel sensor from sadev ! looking for £5k for it , which is what I have spent on it in the last year lol

I heard he was selling all the parts very cheaply ! I would have been interested in buying the box as a spare but you got in before me , which is a good thing as i'm buying a brand new ST82-14 before the end of the year to mate to the rebuilt F3 engine to go in my car as I don't think my current...

How can the mot station be liable for this , there was clearly a fault with your car , otherwise every Clio put through this would catch fire ! sounds like the sound deadening material was not fitted properly and was touching the manifold , so it could have caught fire anywhere , you should be...

Hi Does anyone know what thrust bearing the early UK 172 sadev box uses as its larger than a standard 172 one , mine was lost when the box was sent to SWR and they said there's a few types so measure the clutch plate , but I'm only running a standard plate and thats with Fred at the moment so I...

I wish my clio only cost that , i'm up to around £30k now lol , and i'm looking to upgrade to the larger sadev box before the end of the year adding another £10k to that , but half of that should be covered by the sale of my current box Yes its always cheaper to buy a car rather than build one...

Well if your building a car the seats and belts will be new so in date for 5 years , window film you can do yourself for £20 , I got the stuff from Peter lloyd rallying and did it myself , fuel sampling valve is less than a hundred quid , I see no issue myself so get it built lol. as for the...

My rally car is 920 kg , but I still have all steel panels , glass , and even electric windows , so could go quite a bit lighter

Did you just change the spring on yours , or did you shim it up , if you shimmed it , what thickness did you fit to get to 6 bar ? ​Cheers Ian

Here is my old one One careful owner lol Coleman , I was behind you yesterday on Ewenny Roundabout , thought you were going to have a play but you turned up towards Heronstone , car looks nice , I had an RB5 about 10 years ago , nice cars

Surely you can control the difference in hot and cold pressure with a better choice of oil , if its getting too thin when hot making a big difference in pressure , then a thicker oil would reduce that gap considerably , tbh , I don't see a big difference between hot and cold temps in mine ...

yes but no turbo runs with the wastegate shut all the time , you will get turbo's running out of puff on boosted cars on standard turbo's , my GTR is 600 hp and to go to 750 I need new turbo's lol , but they will produce more boost midrange than needed so is bled off , so putting a stonger...

ok lets forget about 3 bar for the Minute then as they run more pressure than that , speaking to various people they all say the pressure mine was running , 3.8 is about normal , so my pump must have been making more than that to hold it , if not the pressure would have dropped with revs , even...

Yes I know how a pump works , basically on the similar lines of a turbo , a turbo moves air and if it can't move all the air it builds up pressure and the wastegate bleeds off the excess , same as an oil pump , I mean oil mover , lol , see if I prove you wrong then when I mess about with shims...

yes your right , and that pressure is what Renault have decided is right for the use , ie , a standard car , that doesn't mean the pump is as you say made exactly to only run that pressure , each engine will have different requirements as no two engines will leakdown the same I bet , so the pump...

I don't think they are designed to run exactly a certain amount of oil pressure , otherwise they wouldn't need a pressure relief valve , personally I think they will run more pressure , and is capped on the valve , we'll soon see

​Then you just have to get it up to temp before driving it , which is what I do anyway

Well no if the pump can only make 50 psi then no shimming of the valve would change that , but i'm sure all car oil pumps are designed to run a lot more pressure than they actually do and just bleed the rest off via the valve , so I think shimming the spring will make a difference on all engines...

Are you saying the pump can't physically make more than 50 psi of pressure ? have you tested this , and tested shimming the spring to see what difference this makes , it works on all other cars so I fail to see why it wouldn't work on the 172 engine , it works on the Williams engine as you can...

Can you tighten up the tolerance between the pump body and gears ? this will surely reduce the amount of pressure you're loosing , perhaps its worth looking to see what clearance is there on a standard pump , and if that clearance can be improved on. What about running a thicker oil , I always...

Aren't the standard valves in a vauxhall engine nylon ?? They have issues with them sticking and losing oil pressure , happened to me before which took a bottom end out. so what are the mods you say can be done to a standard pump , I can't see after looking inside the pump

Maybe you could just come out with it instead of keeping us guessing then ?? Just taken photo's of a brand new pump I have had delivered to have a look at it , looks easy enough to shim the spring , I guess i'm missing the obvious part about upping the oil pressure ! ​

After speaking to SWR this afternoon , who tell me they used to rebuild a lot of these engines in the Clio cup series say they did used to shim the springs up in the pumps to up the pressure , I'm sure if there was another way he would have told me

just found this but for the F7 engine http://www.ebay.co.uk/itm/NEW-Oil-pump-Renault-Clio-F7R-F7P-Williams-16V-1-8-2-0-/140662351630

I was actually running 3.5-3.8 bar hot under revs , which I agree in my eye's is not enough , my golf rally engine putting out 250hp is running 85 psi hot , just over 6 bar , most cars I have had run at about this pressure , my GTR road car runs 6 bar hot . I can't see why the oil pump springs...

​If you are doing a dry sump kit i'll have one

​i wasn't involved with the build so can't answer that , arrow said it wouldn't show up if someone built the engine and plastigauged it , it would show as ok , is it normal practice to check rods that way before building , I'm not an engine builder so wouldn't know

you can see the oil pressure gauge on the video , there is no loss of oil pressure , if it was the engine design it would have done it back in march when I did exactly the same rally , and the 12 rallies or so I did last year with the same set up , the race cars are cornering far far harder than...
