    Oil pump priming

    several minutes is way too long. i just primed a freshly built engine, it took about 4 seconds to show oil pressure. what i have done with engines that have gone "dry" and wont prime on a drill without repacking is take the oil switch out and pump oil into the gallery whilst spinning the...

    V8 4 speed gearbox - difficulty with reverse.

    change the gearbox mount! the gear lever gaiter tries to pull the box out of reverse, if the back of the box is sitting low because the rubber mounts of sagged the problem is exaggerated, i have cured numerous cases of jumping out of reverse by changing it, including gearboxes which have been...

    Yes you are right in that a turbo will make a good substitute for cubic inches, but it comes at a price, small engines using boost to make the same power as bigger engines pay the price in terms of long term wear and tear, because you have the same loading going through bearings etc a fraction...

    apply the same technology airflow and boost pressures to a 3.5 engine and see how much torque you get then.............

    the owner has the car back now, but i did get to drive it before it went back. wow its really nice and not a handful either. driven normally or briskly you dont really notice the torque curve as such, its somewhat like a modern turbo diesel now it accelerates well whatever gear/revs, whether...

    lack of oil.

    at tickover you wont see much oil, ive run engines on our dyno with valve covers removed its only once you get to about 3000 rpm things start getting messy. but you could unbolt the rockers and check oil comes up the feed holes, but spinning it over on the starter again wont bring much oil up...

    the other thing this does is make me want to build a v8 race car, but then again i do race against rover v8 powered tr7s, morgans etc, with 285bhp my bmw matches or beats most of them on horsepower, but my little old 2.8 doesnt come close to big v8 torque, and most of the time the huge low down...

    you might use all the power but my client wont! just out of interest ive just run it up again, when i recorded those numbers yesterday it was blisteringly hot, the dyno logged 49/50 degrees C intake air temp, its still hot this evening but with a more sensible air temp of 34/35 we pulled out...

    cost would of been same if we had used a 3.9 or 4.0 bottom end, i had a suitable 4.6 available so that was used, no harm in having a reserve of torque that you rarely use, its rare for any car to ever be used to its fullest power potential, what your saying no different to saying we should all...
