iv'e had a set of Porsche wheels for a long time as they have the same PCD as the S800 but iv'e never been sure how to mount them without having special wheel nuts made. they only cost me £100. they are 15x6 and with the 195/45x15 low profile tyres they are the same rolling radius as 185/60x13. they will be used as track wheels as i don't want to damage the 13 inch wheels, they are easily worth £1000 and almost irriplacable. iv'e had a set of Porsche 14x1.5 thread sized aluminium wheel nuts kicking around for ages. recently iv'e been measuring up as i will be changing the wheel studs to a larger diameter from 10x1.5 to 12x1.5 for a bit more strength. then i had a brain wave. machine the ball end off the Porsche nuts and use them as spacers. don't know why i didn't think of it before. just 19 more to do the wheels will need a tiny amount drilling out for the shanked nut to go through but it'll locate perfectly and means a cheap set of alloys for track use the spacer is made from aluminium (Porsche wheel nuts are ally and very light) so will still need the washer as a load spreader. the spacer sits flush in the wheel so it looks like there is just the nut and washer holding the wheel on the cookie cutters are not that pretty but readily available and cheap. will be keeping a look out for some prettier 15inch porsche wheels though.

i had a pair fitted into my Datsun . even had Corbeau copy the pattern from the back seat at no extra cost. they are quite low but i filed extra slots into the adjustable headrests to raise them up a bit

Jack the car up ,spin one wheel and look at the other if it's turning the same direction it got a LSD if it turns the opposite direction if an open diff. only true for a plated diff. torsion LSD will act like an open diff when the wheels are off the ground.

the F20c fuel injection manifold sits very high so this will also cause issues in a shallow engine bay. the way i got around this was to make a lower inlet manifold. it'll knock a little bit of power off as there is more of an angle to the head but at least i don't have to have a stupidly big bump in the bonnet

i think you would do better to ditch the rear subframe because they flex so much and make your own frame to mount the diff and lower arms to. you could mount the tops of the shocks a lot higher then.
race/modified cars that are allowed to move mounting points for the rear suspension relocate the front trailing arm mount inline with the lower arm pin otherwise the subframe gets pulled around due to the suspension wanting to go in different arcs. the original set up has to be able move. i'm working on a V12 E Type at the moment that has a heavily modified and beefed up rear end to cope with the bored out to 7.2 litre V12 torque (has 650 na BHP ). it had to have a Dodge Viper gearbox as it would twist the Jag box internals. (i'll get a picture of the rear suspension set up if i remember)

iv'e driven that XJS around the car park at work. it does have a transmission tunnel, its just not fitted in the photos. it doesn't have any steering lock so everywhere is an eight point turn and when the engine isn't running it's nigh on impossible to move the steering wheel. bits you cant see is that it has double calipers on the front on huge vented discs and to be able to connect the steering an arm is welded to the bottom ball jiont cap. the reason the rear 44 numbers are on backwards is that a girlfriend of Bobs at the time had a "blond" moment and fitted them wrong. after that the numbers on the rear were always fitted in this way. it was so fast that other teams thought they were cheating. so for a laugh they fitted a dummy switch onto the switch panel labeled "Nos"

you could always fix it to the throttle pedal? bit of fabrication shouldn't bee too difficult and as it's just for the ignition it wont have to be spot on.

great photos. iv'e driven the Lister no 13 on the road before the bodyshape was changed back to what it is now, amazingly fast acceleration. (plus there are a couple of other cars in the photos iv'e also driven on the road). i was there looking after a Lister no 27 (not road legal) back to the Lister though, that is pretty much full lock , they are not a car to slide around too much as there is no lock to catch a slide.

Is that the 'Cuda that came from Ray? Looks to be in fairly good order. it is and yes its quite solid. it was also a lot cheaper than the advert suggested given it a liberal coating of Gibbs brand to keep the moisture at bay until it's painted. i just want to go through everything to rebush, clean and paint.

thanks to V8ian i now have a Cortina P100 axle to play with. sadly the pigshead is unusable as the Capri LSD wont fit so the plan is to use a Capri pigshead with the P100 tubes and brakes. the huge 10 inch drums just fit under the 13inch wheels and will be easily converted to 5x130 from the 5x127 P100pcd . they will be more than adaquate for the rear brakes so i wont bother trying to fit rear discs. the axle will be plenty strong enough to not worry about it breaking. i have now purchased a tow vehicle for the S800 thought it'll make a more interesting tow car it has sat for over 20 years and just in from California. i'll need to restore and modify it a little, plus get it road regestered. plan is if i break the S800 i can jump in the tow vehicle and still have some fun

Fitting one carb per cylinder is about air flow, more air = more petrol = more power. not quite true. you can fit one big carb on a log manifold and get the same airflow. it is to do with charge robbing and pulse tuning. with a log manifold and one carb the valve opening on one cylinder can pull the fuel/air mix from another runner for another cylinder so that one then has a low volume of fuel air mix. this is worse with high lift cams and some engines will run really rough until the engine rpm is increased quite substantionally. individual runners/throttles really help a lot with low end drivibility with high lift/long duration cams. the length of the runners can easily be altered to take advantage of pulse/ram tuning. if we take an American V8 for example a four barrle Holly will allow more airflow because there are four butterflys feeding all cylinders through a common plenum individually (remember the valves are not open all at the same time). a Holly fed V8 can usually have more horsepower than a four carbd Weber V8. so why fit Webers? it is for drivability. thats why you see drag cars with Holleys because they are just flat out where as a circuit race car has Webers because it needs the engine to pull from low rpm for the corners. going to why fit carbs instead of injection. when the air is pulled through a carb the fuel needs to vapourise and in doing so it will pull some of the heat from the inlet charge cooling it down. also there is more time for the fuel to properly mix with the air. most injection cars have the injector right at the head to aid slow running but this position hurts top end power as it doesn't give any time for the fuel to mix with the air. look at any full race injection system and they will have standoff injectors outside the trumpet giving maximum time for fuel to mix with the air. what ever system is chosen to fuel the engine they will all have an advantage and disadvantage over each other. bike carbs are a cheap way to have your fuel mixed well with the air.

that is a totally different system with one single butterfly and a airflow plate. all injectors squirt continuously. the Lucas system has individual throttles and sequential injection, basically an early ITB set up.
