Quote from: Doughnutter @ capri v8 driver' I hope I never hit anything again Paul, but unfortunately I'm a beginner and even the pros fuck up from time to time don't think it will sit any lower, thats part of the prob, not a lot of clearance between rad and floor and those motorway cones have massive solid base plate that can bend / break rads / alli easily, especially when you misjudge the clipping point on a 3rd or 4th gear entry and end up a foot or 2 the wrong side of the line you want and end up eating a cone Steel brace is adding weigh were I least want it. looking at reducing front weight and get a better weight distribution, I've already got a heavy big 24v up front, more weight on the nose is not going to help
Quote from: capri v8 driveri was just kidding to make thing's easyer for you, take a look at a vw siroco or audi 80 or a4 diesel radiator's. they are lower in height.where do you have the battery? you could move that one to the boot, if you haven't done that already.greetz paul.capri v8 driver.
Quote from: MikThe aerodynamic diffusers work by cleaning the airflow so that it passes the car with the minimum of effort. most cars now come with basic setups on the front in the guise of an engine undertray. This reduces the amount air from under the car entering the engine bay as this increases the engine bay pressures and reduces the airflow through the rad. Anyway, at the back the same principal applies. Place a smooth bellypan under the rear axle to the rear bumper to smooth the flow from the rear of the car. There is still turbulance, just slightly less violent which in turn, reduces rear end lift. You can improve this further by placing vertical slats or fins to the rear of the belly pan.This is not ground effect and will not produce downforce, it just reduces lift. To produce downforce the car needs to be drastically lower, have a near perfecly smooth floor and the rear diffuser needs to have a triangular side profile (look at the back of a DTM car). This moves the low pressure zone under the rear of the car which in turn pulls the car down(high pressure above the car). All this is well and good and can look very trick and will help straight line stability and cornering ability no end but once you've got the car sideways, it means f**k all.Mik.God, I wish I could learn to type faster.
Quote from: JFB TechThe Cossie rad is the same width as the standard Sierra but it is nowhere near as tall. In the Cossie, it sits at the bottom with the intercooler mounted above it. Overall it is about 4 inches shorter top to bottom, fabricate some bottom mounts or possibly even bolt it to the top of the chassis rails rather than underneath as normal. This should raise the bottom of the rad by 4 inches. A traffic cone is unlikely to bust your crossmember or sump so problem solved.
Quote from: DaveI have seen a couple of Sierra's with rear rads.They had the spare wheel well cut out & it's mounted there.Just one rad, using STD engine pump & electric rad fans.I think the underside of the car is low pressure, so get the fan direction right, seems a common mistake. Do check this out as I can't remember if it is or not.Also bangers run rads the same to protect them but fitted where the rear seat is.No special pumps & STD rads. The extra water volume will increase the cooling capacity.Any weight moved to the back is helpful.
