    Weight of a RRC chassis?

    in Range Rover Forum

    Posted

    Hi Reggie

    I have used a bathroom scale and did as below, acctually the workshop now posseses one cooking scale, one bathroom scale and a postal scale for the nitty-gritty bits, as we are car weight watchers not body weight watchers :lol:

    Placed the one end off the chassis on axlestands as close to the end as possible and the other end did rest on a thick playwood

    piese then I read the scale noted it, did the same in the other end added the two figures and then you have an approx weight close enough for my purpose and I guess also for yours.

    regards

    After 10,000 posts I suppose eventually one was bound to prove useful :P

    Also I haven't forgotten I owe a donation from the assorted tat from the shed I foisted onto various forumers a while back - maybe we should have an LR4x4 autojumble somewhere, or even just an LR4x4 yearly gathering?

    A yearly gathering would be fun, would go a long way to participate

    Kind regards

    Hi

    I say TIC and I have done it before; TIC it is there is no substitute for that quality and service have had several sets on different cars, they do not sag, they do as a para spring are suppese to do and they last for ever...

    The ones we have on The Kitten has taken a lot off abbuse and are still fine.

    Thats my words

    Kind regards

    Hi Steve

    I think there is two aspect when talking about springs, flex and comfy, me experiences is that you can get both with both types, BUT and it is a big one I do not know of any one that today makes OE or eq to that springs in the same quality as the old OE springs from LR.

    But if you can get OE 7 leaf LWT front springs and refurb with grease and so and a set of OE 109 STW rears and then fit HD 88" dampers you have from OE std parts a good compromise, but do not buy any of the carp that is being made today, thats my experience.

    Para wise, I do run TIC's ( 2 lef front and 3 rear) on The Kitten with some extra long shocks and we have same flex as a 2" lifted 90" but it is a little stiffer than the above setup ( the kitten weighs 1550kg ready to run less the two monkeys :lol: ), we have a anti wrap bar on the front and are going to have one at the rear in the future also, but the the Kitten is solely used for competition.

    Thats my adwise based on 30 years with series vehicles.

    K&N on a snorkel?

    in Defender Forum (1983 - 2016)

    Posted

    Hi

    Thats no good idea, it is best to have the filter protected from water spray that might hit it at lets say 50Mph.

    So under the bonnet and in a closure to keep the heat from out off the intake system.

    Regards

    Ole.

    Ps actually not filter is /as far as I know) ment to be fitted at the top/end of a snorkel.

    series transfer box

    Hi Brian

    If I understand your correct then you are asking if the speed of the props to the diff's,and IE a prop driven from a PTO fitted to the back off the gearbox are the same in lowgear?

    The speed is not the same there will allways be the difference that the transferbox makes, wether in low or high range, the PTO however follows the main gearbox IE in 4 gear the speed is the same as the engine.

    Dont laugh-but my 2.5NA 'performance' project

    in Defender Forum (1983 - 2016)

    Posted

    I think it is a great project. I just wanted to point out that spending effort on the ram thing was not worth it. As stated, getting cold air is more important. Freeing up the air flow, getting as high a compression as possible, setting the timing correctly, making sure the pump and injectors are as good as possible are the things to focus on.

    Here is a good controversial topic to consider for seating in the rings to the bores.... http://www.mototuneusa.com/break_in_secrets.htm

    Hi

    That is they way to do it, we have done so in almost 20 years now with great succes, so go a head.

    Hi

    A little more info, I have done the porting and manifold matching on a 2,25 diesel way back 20 years ago fuel up by 15% freeflow exhaust 2,5" and an very unrestricted airfilter with cold air feed, I had for the size off engine, load off pulling power, could not prowoke black smoke at all it gave, when I cruised at 50Mph, more than 10% better milage, but it would almost outrun it self in the higher rev range so one had to be carefull.

    Re the cam on the 2,5 na diesel and petrol the cam is the same, to me it says a lot about how de-tuned the petrol engine is.

    I have heard of people using the ACR cam in 200Tdi's but I have never heard off how the result is.

    I have my self drawn all the pre 300tdi 4 cyl landrover cam profils on paper also the ACR performance one, it has not much more lift and not a lot more duration but it has faster "raise" times on the lobes, wich is possible because thes engines have "roller" cam followers as far as I know.

    In other words the area under profile is larger without having a lot more lift and duration, tha tis also why ACR cams are made from blanks and not just regrinds.

    And Aragon you are right re cost and result, but he aksed us not to laugh so we wont because some us has been there just because it was possible not everything in life has to be rational :D

    So go for it

    Hi

    My comments in bold

    Air Inlet will be aided by a Mantec snorkle with a Safari head to help with the 'ram air' effect

    I sincerely doubt an extra yard of intake plumbing is going to aid air induction, and I don't think anyone has ever come up with any evidence of a ram-air effect outside Safari Snorkel's sales blurb. It's not a V2 rocket. I'd look at sticking a 110 V8 filter in, they're the size of a dustbin so should let it breathe more freely should the standard filter be insufficient.

    I have done some measurements on such a set up and the conclusion was that below 50mph there was more restriction with a snorkel set up and above it gave a tinny tinny less under presure in the inlet manifold, I can not remember the figures it is close to 10 years ago, so you are right John.

    It is much more important to make shure that the engine gets coold air from outside the engine bay every time you increase the inlet temp by 10 C you lose rouhgly 3% hp :(

    The aluminium inlet manifold casting will be smoothed internally and possibly enlarged slightly.

    An 40-80 grit grind surface is usually ok.

    Don't smooth it too much or you'll ruin the airflow, air likes a matte surface not shiny.

    Any other ideas?

    Supercharger, propane, NOS, diesel-electric hybrid, twin engines, convert it to two-stroke...

    Ricardo have done more than a little engine tweaking over the years, check Wikipedia for some inspiration :P

    And as others have mentioned it is not at all cost vise a good idea, but for the expeience it is very good and fun and good to learn from

    Diff Pegging

    Hi Soren

    On my first attempts I did not use anything but a bolt with a very very little radius at the end and it also work and you where

    not in doubt that it worked one could hear it but as others have mentioned it is so short time it touches so no prob.

    Regards

    crown or ashcroft

    in International Forum

    Even the diffs pegged and installed by Ashcroft himself can break after two 12 days driving, that is two european competitions. And I do realise, even during competition, that diffs can break up, so drive accordingly. However, in a competition the idea is to go as fast as you can. I just hoped there was someone out there who had first hand experience to tell if crown ring and pinions would be any stronger. I think it's not so much the bhp but the torque in situations with on and off grip, going with some speed up a steep hill. If the roadbook sends you there, you just try to go up, and hope that nothing is breaking down.

    Hi

    Just a question out off couriosity, is mainly front or rear you break?? or just both off them.

    Welding In the Field

    in Tools and Fabrication

    Posted

    Hi Folks

    We did it last year at the annual national LR meeting, it was one off the tasks at our "trophy", the teams had to weld to 5x50mm plates togther,they where supplied with two rods a set off jumper cables a plier to hold the rod and finally a pices off normal window glass and a candel!!

    Now it is the last two bits that are interesting, you simply use the candel to "blacken" the glas until enough to use as eye protection, I know it does not protect the face and also the eyes not perfect but we are talking field repair under certain circumstances.

    All the teams did the task and about 80 people total now know whyy to carry welding rods and jumper cables traveling and competing in the outback.

    Just my words.

    Regards

    Ole.

    Ps they also had a normal welding helmet as this was not a "live" situation.
