    Engine Mounts - Drivetrain Misalignment

    "It's impossible to imagine all but the most stupid inattentive drivers could not notice something is seriously wrong. Yes I know we should not underestimate the destructive talents of idiots or imagine they are in short supply. Regards Pat" Quite possibly the most accurate statement ever to...

    Fuel Filler Location

    Several makers have taken the "central filler" route more recently and most probably Triumph TR6 being the most well known. Jaguar and Aston-Martin also side stepped the problem with filler points on both sides of the car for some of their models. Added costs and complexity but made finding a...

    Exhaust Manifold Primary Diameter Sizing

    Michael, You might find flex tube or even vacuum cleaner flex plastic tube a more accurate substitute. This tends to give a better approximation of the space required. Peter.

    Watts Z-Link on GM Cruze

    Norm, The only other car using cantilever springs for location I can recall is the early MkI Jaguar sedans circa 1960 / 61. Yes the Sprigets were a little "twitchy"...downright treacherous if you really want to be honest... but a great fun drive and all at or below the legal limit in most...

    Smoke Test

    Certainly is...politicians have developed it to an art form! Peter.

    DOHC valve angles and centerline

    Lambent 32, have a search for books by Ian Falloon on the Ducati DesmoQuattro and other Ducati engines and also for a book by Alan Cathcart and Marc Cook on the Ducati 999. Both discuss the valve layouts , angles , packaging requirements etc in detail and Falloon makes comparisons with...

    Look what they got away with

    Related to the above posts is the dimension used by Rolls Royce for their six cylinder inline engines. It remained the same for 44 years and there was a paper written on it. The title was "The History of a Dimension" and the writer was G.S. Grylls. Link below for those interested...

    Roof Rack "Wind Tunnel": A Naive Idea?

    Autogyro, One point which may complicate matters is isolating the signals from the test model from those generated by the motion of the carry vehicle to give accurate data. Never done it so I am not sure how much of a problem it may be. Interesting thought though. Peter.

    What are interior body panels made of?

    Rick, If the adhesives don't work as you want you might try locating a place performing plastic welding. Local phone book , car clubs etc are usually good sources. This can be done to appear virtually undetectable from the inside of the vehicle. Good luck , Peter.

    Jaguar IRS question

    There were two main reasons for the Jaguar arrangement: The first as Lionel Hutz suggested being a flat floor for the luggage compartment which was a complaint from some about the previous car. The second was to allow the rear subframe to be installed and removed as a unit since the coil over...

    Is there any point in wind tunnel testing a 1:43 scale model

    If it is of any help here...Citroen used scale models for their cars in wind tunnels and the smallest scale was 1:10. I recall reading a comment from them along the lines that anything less was not sufficiently accurate to base decisions on. This was back in the 1970's so it may well have...

    Moulton Hydragas and Creuat: coupled hydropneumatic springs

    autogyro46, I suggest the main reason no other makers "picked up the ball" is simply the cost of paying Moulton to use their system when makers like BMW can engineer one of their own and not have to pay anyone to use it. One practical aspect of the Moulton hydragas / hydrolastic set up is the...

    hypiod gears

    " Historically speaking- I believe that hypoid rear axle drives came into being simply to allow lower floorpans of vehicles, rather than any other particular advantage. Any comments? (wouldn't be the first time I was mistaken!)' Basically correct. The earliest cars sometimes had worm drive...

    In search of Bell housing bolt patterns.

    archangel, there is a dedicated 215 chat group on Yahoo if that helps. No personal experience with either the engine of the group. Also this engine and variants of it are a popular option for Z car (Nissan / Datsun 240 , 260 , 280Z series) modifiers so a board for them may provide some leads...

    Prius Mileage

    msquared48 , There are a few Prius owners groups on the internet and perhaps one may hold the answer you are chasing. This is the leading item according to Google: http://www.priusownersgroup.com/ I have to agree that is a significant drop. Wheel alignment alterations possibly? Pete.

    Rotating Mass weight and fuel economy.

    TxGat, The largest influence on fuel economy is the driver and the use of the right foot. If FE gains are what you are seeking then altering your driving style is the most effective way to get them. There are a couple of sites worth looking at listed below: http://ecomodder.com and...

    Purely mechanical system to give a continuously variable gear ratio

    Nemisis4, Napier built an aircraft engine using a series of tapered discs as a variable ratio drive for the supercharger. The engine was either the Sabre or Nomad if I recall correctly. This may provide some leads. Pete.

    Purely mechanical system to give a continuously variable gear ratio

    Nemisi4, "fishwrapper" does indeed refer to newspapers usually tabloids. The name derives from the using of newspapers by fish sellers to wrap their products. Pete.

    Valve grinding

    One extra point ...expect to pay for this. It does take a level of experience as Evelrod pointed out as well as time and constant checking ; all of which costs money. Good luck with the rebuild and running. Pete.
