Can someone tell me what this box was originally from? Also it has 4 bellhousing mountings whereas I see many -2s have 7 mounts. I have a bellhousing that has the 7 mounts. I guess its not going to be able to be mounted up to this casing - without recasting a new bellhousing? Your thoughts...

I would like to hear your ideas for compression ratios for an engine. I know that too little and the power isnt there, but too much has its dangers. How much is 'too much' and what would be considered a reasonable amount for a good street/track engine? I realise there are contributing...

Im looking at a new engine for one of my cars. The car is set up for an SBC engine (I know Im treading carefully in Ford country here!) Id like to do a 4.125 bore with a 3.25 stroke and 6" rod combination (this will give me around 352ci). The car is light in weight with a manual gearbox. Im...

Can anyone tell me please, what they are using for CV joints on the Ricardo gearbox? I have meaured up to see what the pcd is, and its seems to be a somewhat unusual size. The standard Porsche 930 type joint is about a 1mm or so different in its pcd. Thanks.

Could anyone please measure for me, the distance from the centre of the output halfshaft, to the front of the box where the bellhousing bolts on, and the distance from the output halfshaft to the overall rear of the gearbox. Thanks.

I have just landed myself a Ricardo 6-speed trans. Can anyone please tell me what the shift pattern is for the box? I cant seem to find reverse on the bench!!!! While Im at it - a punt for RPM Transmissions in Indiana, excellent guys to deal with.

Here are You Tube videos of valve float and spring dancing. There are a lot of others on there, but this will give you food for thought of whats happening inside your engine. YouTube - Valve Float YouTube - Valvespring at 7000 RPM

Does anyone know what, to the betterment, of front suspension geometry can power steering offer? We all know it allows the wheels to be turned easier, but are there benefits of having different geometry that makes the wheels harder to turn but a better wheel/road relationship and hence require...

As we all know, under braking, weight is transferred towards the front of the vehicle. Is there any relationship between suspension geometry/centre of gravity and the transfer of weight to a particular point on the front of the car? To get an idea of where Im coming from, does the weight...

Ive just aquired a set of 4 x 48 DCOE carbs. I got them rather cheap so thought I might add them to the workshops shelf. But I had this idea. I have a cross-ram manifold to suit a set of sidedrafts for a V8. Now instead of rebuilding them and buggering around with jetting and other manner of...

Could anyone tell me, about power figures that are quoted using rolling roads. Now - heres my question. In what gear are readings taken? To put it like this, if you took a reading in first gear, there would be more torque available to run the rollers, and hence a higher figure than in say...

I am in need of a ZF 5SD25-2 transaxle, and if its out of a Pantera, the half shafts as well. Any info welcome. Cheers Bruce

Apart from the usual side ID plate, what is the difference between the 'boxes' with regards to the side plates around the diff area? Some are fastened by, I think 7 bolts and others 4 or 5? Is this an indication of strength upgrades over the years or something else? I know the original design...

How many of you have thought about using Porsches 'TipTronic' gearboxes in your cars?? I see they are somewhat plentiful and at the right prices. How about this?? Convert it to a manual clutch - toss out the torque converter and put a normal flywheel and pressure plate in. Then build...

I have been searching the site now for a few days and cannot find the section that has club videos and downloads. I did come across it one day last week but cannot find it again. It showed various video downloads from club sprint, hillclimb and track events. Seems the only thing missing from...
