Anyone know who makes the GM oil pumps?
Anyone got any gen on where to get an OE oil pump?
Want it to be OE spec as I've heard there is a lot of pants pattern parts about and I'm not gonna risk a 5.5k engine just to save a bit now. - However there is also no point throwing money away so if I can get the OE part cheaper I will.
VX wants loadsa money for one and so I'm trying to find someone who supplies with only a 'normal' amount of mark-up put on it.
Being a bit of a sado I've done a work & cost schedule and reckon it will be up together and running at the end of December after spending another £4k on it (yes just the engine). I know this sounds like a long time but there is still alot of work to do both by me and by other companies. This includes work to rods, having a new exhaust system made (the spare wheel well will be coming out for that), work to head, block etc etc.
Gary you especially should be able to appreciate what it's like having to wait on parts to be made and altered, coated, worked on etc etc, and I don't want to rush or bodge things as I want to get it right (or thereabouts) first time. Also being a family man and having a full time job restrics the time I can deadecate to it.
Ho-hum, I'll just keep ploding away at it.
Quetin Hazel - do they make the OE part or the pattern sold by Auto-vaux. I got a price off them ages ago of £70.
Does FAI ring anyones bell? A local factors I use (they sell LUK clutches etc) can get these @ £70 a time as well. Anyone know if these are the OE ones?
Anyone got a pump (or a piccie) to look at and see if it's stamped up?
The conrods I bought of Animal. They are the Arrow ones ABD sells. Some how Matt picked up some dirt in the oil and this has contaminated the little ends. I therefore have 2 options:
Give them to South Cerny (recommended by Swindon) and they will install new copper (?? i.e. std type spec) ends in for £100ish.
Send them back to Arrow who can either put new origional spec ends in, or ends made from Beridium (sp?). - This stuff is supposidly the dogs nadgers.
Although comparably expensive I'm leaning towards the Arrow Beridium option as I'd rather spend more now and be happier my engine will take the (aimed for) 330bhp (when on nos). Also it'll be a good build for any future ideas.
If I go down to SC I wouldn't mind saying hello as you're not far from there are you?
Home is towards Brighton but I work in Brentford so I'll probably wonder over in the afternoon to SC's one day.
I am going for the rough 225 spec (cams).
Arrow say the B stuff they use when on an engine 'stressed more than normal'. My thinking was that with the nos running there would be a fair amount of stress there, and although probably not going higher than 8k I might in the future so building in a little flexability now as the oppertunity is there would not be a bad thing.
Evene if I do go to arrow I might well pop over some time to say hello and have a gander if thats ok. I work near Heathro so it's not a million miles away.
Well if I hadn't already got the MBE I would be doing something clever, but as I'm now limited by it, it does look like I'll have to do the nos by shorting the air temp sensor. However I'm not using the barometric sensor so I might ustilise that. I'll be using a programmable progressive controller for the NOS side of it.
Had a conversation with Steve B and he has done a nos car before and the temp thing is how they did it.
I'm gonna have another conversation with him about it and maybe give MBE a call to see if there are any clever options but I'm not too hopeful.
well technically it's possible to fine tune it, by shorting it, you will be forcing the ECU to take a value from way off the 'bell curve' of the air temp compensation map, so as long as the value you put in there is calculated to give the right amount of fuelling for the size of jets you will use, it should work quite well.
not sure if the baro will have enough of an effect - though again, assuming the baro comp map limits are wide enough, same applies I guess.
you could go one stage further, and take the sensor out of circuit, substituting R values as the nos starts to kick in - that way you could fuel correctly as the nos controller progresses in -this assume it has the ability to output what nos stage is active - I assume it would.
are you tapping the TB's to get the gas in, or using an injection plate somewhere ?
If the controler can 'talk' to the MBE then that would be the best way. I need to talk to some NOS guys in the know then some MBE experts.
I was looking at running yellow injectors (got some off Richie) which should hopefully run engough fuel. Again I'll need the info on the NOS and MBE then do the math.
Ideally I'd like to be able to chage the BHP the nos makes so I can go a bit subtle when I want and silly (100+) when I fancey, but I don't know if the 'outthe box' nos systems will give me this. The ones I've looked at so far won't.
As for placing of jets They'll go where ever is best. I'm thinking that tapping the TB's will give best positioning and mixing with the fuel, but again I need to find a nos guru to discuss the finer points of it all.
I'm sure with some effort and help I'll be able to get it all to do what I want.
