    Re: Ford Taunus TC2 Rallycross

    Here are some pics of the rear axle.

























    An other question, can anybody tell me what for a axle this is. Last time somebody that worked for years on ford said it was an atlas axle. I just cant believe him, i dont think that they ever put atlas axles in the Taunus. But from pictures i have seen that this looks like the baby atlas, And that they are not to bad. Anybody an idea?

      Koln axles were usually fitted to cortinas and taunuses I believe.

      Regarding your spring problem, if the rear springs are too hard you won't get weight transfer to the rear on acceleration and therefore you will have less grip. The axle bounce (tramp) is most likely due to the void bushes in the top locating arms allowing the axle to wind up, then rebound.

        You mean the 2 above the diff or the 2 that hold it to the chassis? or both of them?

          Normally the 2 above the diff are the worst, but you should probably check / replace all of them if they are the original rubber items!

              So from the advice I got from here, I stuck new poly bushes all around the rear axle. Was a fun job drilling the old rubber bushes.

              And also I installed a second panhard rod ( i think dont know the english name) So it should be stiffer in the back and looks at the moment now.

              Some pics



















              So thats for now, Going on a little vacation and the the car in going to a rollingroad, for tuning, will show graph from tests.

                arieke, that looks like axle tramp is going on when you start.

                some tips when i was starting of that same line in the escort :p

                get the rear softer inbound, there is hardly any weight transfer to the back, the rear of the car doesnt drop down when you lift off. the rear seems too hard. look at the starts of the volvo's in rallycross, they almost hit the ground when starting of the line.
                try to fit anti tramp bars to prevent it happening : simple installation. there should be plenty of pics on the forum. Or install a 4 link system that you set up so the car drops when starting from the line.

                i had the bugger axle tramp when i still had leaves on the escort. when i installed a 4 link system with a Z-bar is was gone and dramatically improved the overall handling.

                  in the uk, cortinas had a variation on of the atlas axle, so they are atlas's but not quite the atlas we have in our capris

                    thats an anti roll bar.

                    a panard rod connects one end of the axle, the the chassis on the opposite side of the car ro stop the axle moving sideways

                      Re: Ford Taunus TC2 Rallycross

                      u have a koln axle there, some cortinas here that had the atlas type axles, i believe they are mk3,4 and 5's 2l + and some towing packaged cars had them fitted, if u can find one u can fit capri slipper

                      To tell a heavy atlas type look at the bolt pattern on the diff plate if its symmetrical its a atlas type

                        Re: Ford Taunus TC2 Rallycross

                        Yeh that's a Koln (or chocolate axle) IE get it warm and it melts
                        TBH with all that rear anti roll bar stiffnes your turn in will be very direct and cause more overstear
                        i use a hyundai rear ARB it's 20 mm and about as far as i like to go on the rear
                        Ii don't like to fully polybush the rear end, for 1 it will start to crack the mounts at the chassis end and it limits the axle movement and makes for a very very hard and skippy ride especialy on bumpy corners, personly i'd be softenong the rear and using rubber bushes at the axle end of the arms, if you want better axle locatuion you need to go back to rubber and add a panhard rod (if you can find an 81 to 89 hyundai stellar they have a cortina rear end thats 5 linked with slightly alterd bushes and a way way better than the standard taunus set up

                        Although that is all based on playing with them for road use, never really rallyed one seriousely

                            So we went to a rolling road.

                            The previous driver said it had 171hp. So, ... This guy, he set everything up, did first run and said its overfueling. To large air of fuel tubes. The previous owner had 170 (these were drilled) in the carbs, but it was overfueling, So he got some other and put 145 in the carbs and the engine made 150hp at 6100 rpm and same torque, So second run he put 140 in and the we got this.





                            For a standard rs2000 engine I must say it aint bad. they had new 150hp and 190nm torque I even got 10 more. The fast road cams will make a difference. But that will wait they will fit in the rs2300 engine.


                            The previous owner should have had the same probs with the overfueling,right?? it cant be from, something I did. Because i didnt change anything. I dont even believe the engine had 171hp because overfueling you always see on a rollingroad.


                            Would rather see those 170hp. But he said his rolling road is a bit off. So ...

                              I think pretty much all dynos differ from each other, they're only really usefull for comparisons if you use the same RR every time to keep track of the mods you fit IMHO.
                              That's still a pretty good result though what sort of millage has the engine done ?

                                nice to see someone doing something original for once!
                                also, i think the matter is that the man told you the bhp at the fly wheel (so it seems powerfuller than it is at the wheels) the dynor might possibly have told you the bhp at the wheels
                                hope this helps
