My stink wheel on the dyno

[lee bishop]

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.

That's decent power Lee,well done.

Can you see the two vids ??

[kas750]

How good does that sound!

Plenty of horses from 3,000 up Lee, pretty linear trace too.

Neil is a good chap.

Sound mint Lee I want one

[Escort TC]

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.

Spec as follows :-

701M block 85mm bores x-flow/BDA cast crank double dowelled 77.6mm throw = 1760cc
Farndon steel rods
J E custom forged pistons
Big valve head inlets 1.6" exhaust 1.4"
QED 360 camshafts ( their sprint cam equivalent ) top out at 6500 rpm
Compression ratio 12:1
Burton modular water pump conversion
Standard twink exhaust manifold
B8ES plugs
Luminition elec ign

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 ****

Carbs are the correct original lotus matched twin 40's 0031
F11 emulsion tubes
120 mains
155 air correctors
45 F8 idle jets
34 mm chokes

What's betting mk1 Gaz will be along later to put you all right !

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

[lee bishop]

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 !
