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.

Hi Lewis
Are you happy with the performance, did it make a lot of difference?

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 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
