Advice on some Dell'orto DHLA 40

[carlo rossi]

OK stock as between 74 and 80 hp at rear wheels if you use a mainline dyno
dynatech will be 5hp higher
then you add approx 50hp for the losses of a transaxle giving you about 124 to 130 flywheel
thats foe an alfetta
spidewr with 105 tranny
should get 80hp to 85hp rear wheel then add  35 to 40hp for flywheel hp

Got the cars back.  Starts, idles and runs really well.  Flat spot gone & quite responsive.  Took it for a sprint through Galston Gorge yesterday, and it accelerates out of the hairpins really well.  Used to sputter on hard acceleration on the tight corners.

Attached is a copy of the Dyno report.  Folks at Classic Alfa are suggesting this camshaft for both inlet & exhaust : https://classicalfa.com/products.php?product=EN521-11.2mm-PERFORMANCE-CAMSHAFT

Worth a try?

Looks good as it is, a nice road driving setup for our speed limits and practical limitations of the car's type/age.

whats the red and the blue line ? as in there are 2 cars? which is yours
because  thats 85hp and 90 hp between the 2
the torque is interesting normally it would start lower then peak around 4000rpm and slowly go down fairly flat
what is your jetting ? as you see there is a second peak at 4000 the under 3500rpm graph is  wrong or you are running super lean idles
what brand Dyno would be helpful as well looks like a mainline
sounds like a healthy engine  thou well done
also with the cams see if you can get the 10548 ....51 cam
its excellent or the cand b 10.9 mm cam dont have to modify the head
slighty less timiing that the posted one but less hassle and cost
also the spica injection was a brilliant design 4 throttle bodies  4 injectors it was a piece of art and mastery
effectively injected dellortos their only issue was they really didnt like cam change you had to modify the mechanical program
alla wes ingram in the US
which if it came with carbs and it has 90hp its probably got  10548...01 cams in already
you should lift the cover and check
