It would be nice to see your setup finally running, as I didn't get to see the last one get finished. Just make sure you finish this one.
This will get finished soon am hoping in a month, the last one who bought the kit was on his car and dynoed on 1.0 micra he had at 79bhp which was on low boost, I'll try and get dyno sheetsIt would be nice to see your setup finally running, as I didn't get to see the last one get finished.

[quote="Azzydot, post: 659664, member: 15800"ill anyone need any t25 manifolds making cut and shut with tig welding on them,

I have welded and cutted k11 flanges and the last turbo manifold I sold the man never had a problem of any kind, @micramarch will tell u about my weldsThats not what I said mate
It doesnt matter how strong the weld is if you have a brittle grain structure around it. It will shake apart and crack within a couple of weeks (im talking from experience ).
Yeh that's fine I have done mines how he has mentioned as the casting onto mild steel is harder to stand the heat and can wear off .I have grinded my manifold and same with mild so it holds strong, although I will do checks on it weekly and weld it if needed every month or soAzzy Noddie just trying to help you out with a tip for welding Cast. I have seen Noddies Welding too, He welded my Manifold .
My engines all sorted, only left now is put my build engine in my car and fit all my pipes on and intercooler, wire my injectors on Micra loom, and maf wire, then to eds really to get it mappedSo what's left before you can have it on the road then pal?
erm I think you mean the other way round? if it slips before it reaches your "good" target peak power, no more torque energy will reach the dyno and the graph either flattens out or drops down resulting in a "rubbish" peak power.What if it does slip and makes good power ?
Yeh that's true u spotted that well I didn't relise till u posted thankserm I think you mean the other way round? if it slips before it reaches your "good" target peak power, no more torque energy will reach the dyno and the graph either flattens out or drops down resulting in a "rubbish" peak power.
like any friction mechanism, whenever it starts to slip and goes from static friction to dynamic friction, the CoF drops and only a portion of torque is transferred to the drivetrain, wheels to turn the dyno.
The rest of the extra torque and revs is basically converted to and wasted as heat which further lowers the CoF and gets worse.
@pollyp I mean it might slip before I even got a good target and waste of time money, so am gona do it right first time

1 thing Polly do I need to bread in my clutch for 500 miles ? As once it's done I will start it up and past it to Ed ? or am I doing it wrong ?yes, get it wrong and it'll be a waste of time, effort n money.
the other scenario I was gonna post is when it makes good power but then starts to slip/glaze over time, which is what happened to my badly bedded and badly abused 3-pad helix clutch when it glazed and again was wasted time & money.

I know how u mean, but I can't drive it without a remapped ? coz it will over fuel, I should have got the clucth before in Micra left it n/a and drove it 500miles then swapped it backto achieve the products peak performance, yes.
just like brakes, they need bedding to get the most performance out of them
@Noddie yeh I preheated mines with my tig Torch going up and down makin sure it's really hot and didn't miss no bits of the cast then I welded it up

I have pre heated it I know how casting is, u can tell by looking at itWhat noddie means is you should pre heat the whole manifold I.e stick it in the oven for a bit.
My old man is a tool maker by trade and spent years fixing cast items. Molds etc and he's always said that you should pre heat the job. It provides a more even heat distribution which helps reduce the chance of cracks when the piece cools.
I can't really do that, coz the Injector are bolted in a tight seal in the inlet, and once I wired them up I will have to rewire it all up, and my maf will be wired, but taking all that off it's worth it coz I'll be running probleyYou can leave the turbo on and running it close to standard by doing the following :-
Leave the wastegate actuator off, put standard injectors and throttle body back.
So long as you haven't modified anything else. It will almost be standard. You Turbo will not spool up, because the actuator is off. It will save you have to put everything back as standard again.
Can't you use your spare fuel rail to make things easier to take of and on.I can't really do that, coz the Injector are bolted in a tight seal in the inlet, and once I wired them up I will have to rewire it all up, and my maf will be wired, but taking all that off it's worth it coz I'll be running probley

I have preheated it so it's red I did make sure the part am workin on for the weld is nice and hot and clean then weldedTBH you need to get the cast close to red hot for any noticeable effect from my experience, and then put a metal bucket or similar over it to allow the metal to cool slowly to avoid cracking (from my experience with cast stuff, although that is 1800's material technology...)
My fuel rail is Diffrent to the one am using and the ones am using are bolted on the inlet manifold if I take of the bolts the seals will never go back in place as they expand in place when they fittedCan't you use your spare fuel rail to make things easier to take of and on.
That's other way yes get base map to drive it and bread it inI see leave it, just let Ed know the mods you are doing/done. He may be able to send you an ecu with a base map, to allow you to drive the car around safely.
It will only allow you to drive slowly at normal daily driving speed. It should help resolve your dilemma.

Bread? Hahahaha
Haha yes bread it in then some welly after that
I can take gearbox out but I don't have a crane only 1 jack and k11 jack, 2 axle stands, so that's my options onlyI reckon If you have no problems and you take gb out aswell (seems easier imo if you have a crane to get gb out aswell) then hour and a half if you know what you're doing
Polly how long does it take u to take your engine out and refit it ? Do u use a crane ? Or by lifting it ?
