Rufus power!

Just had my carbies tuned and the car is running sweet, Out of curiosity I had Rufus run up on the dyno after the engine rebuild (plus 600km). Interesting that he made 98.4hp@4900rpm. Seperate test to 5200rpm 170kph showed a level off.
It only has a mild cam 1/8" bigger extractors and a bit of porting. Carbies are too small to achieve any more power. Not bad considering manufacturer's specs show 91horses at the flywheel 8- Good flat torque graph too, higher than manufacturers rating.

car looks good ..... all the work you have done on motor and only gaining 7 horses over standard not good

you would expect more

thats rear wheel HP, not quoted engine power. There are losses in the trans. so the rear wheel HP measured is pretty good I think.

Thats a big improvement the best guide would be research whp stock on 13 inch wheels/tyres

i think you would be supprised.

Yeah Geoff, considering a manual transmission car typically loses 16% of its flywheel
horsepower that means my engine is producing 133 net HP at the flywheel, whopping 45
more HP than standard G161. Greg, I am running std profile 13" wheels.
How did Mildred's 1st big drive go today?
I have been installing my new quarter window rubber seals today.... Bit tedious, and I discovered why the
LHS was siliconed shut... The top pivot spot weld is broken off.

if araldite doesn't work the window will have
to be siliconed shut again
Cheers, Lewis

Lewis, as you will have seen, I have spare GT doors so if you need a top frame, let me know.
