  • My stink wheel on the dyno

    Went over to salisbury yesterday morning ( in the pouring rain ) to have stink run up and see what the boat anchor was chucking out. It was an interesting morning and many many things were tried to eek horsepower out of it. The final result was 133 BHP @ flywheel and 117 @ wheels. 119 lbs/ft of torque at 5000 rpm. Couldnt work out why the power dropped off so drastically at 6500 rpm but i have since learned that is typical of QED cams. The engine has steel rods and forged pistons but its all pretty safe if its not going past 6.5k so should have longevity.

            Neil is a good chap.

                which carbs and carb spec., camshafts, camshaft settings, cc, Valves, Compression has the TC. The dyno sheet locks to me like SE Cams with 40 Carbs and raised compression with big valves.

                My Rallye/Street TC is 168 @ 7290 , 181,7 Nm @ 5460 (134,5 lb) with Full Race Valves, 45 Carbs, many Compression and old Piper 8FR2 Cams.
                And my originale Holbay F2 TC is 185HP @ 8090, 183,8 Nm @ 6060 (136 lbs) on 45 Carbs. With Lucas Inj. it is a little bit more. For the F2 Engine i have the originale Dyno Sheet and this is very similar to my Roller Dyno.
                Both Engine are mounted in Escort MK1 with same Gearbox (ZF 0,87) and Atlas Axle 5,1.But is a big Diff. to drive.

                    Forgot to add distributor set to 27 deg of advance which I thought was low, but this is typical of higher compression ratio's I've since learned. We put it at 36 deg for one run and lost 20 hp and it pinked like ****

                          Have tried to get rid of the dip @ 3000 rpm?

                            Yeah i just think its a little step coming on to the cam. I could have probably been smoothed out but bottom end would have tailed off. Interestingly when the air filter element went back on torque at the bottom improved !
