Hi and greetings from Finland.
I have been reading this forum with great interest using the translator because my Hungarian is non-existent. Very nice to see classic old Ladas being developed even today.
But one thing caught my eye, very little dyno charts from 8v Lada classic engines. I like to put all vehicles in to dyno, great fun and great development work. My Lada is not an exception, it has visited the dyno many many times.https://www.dropbox.com/s/9trvswfo1u81b ... 193710.jpg
Here's my results measured in a very accurate dyno. Right numbers are from the crank.
Since these figures loads of development work has been done, in 2014 spring I'm going to visit dyno once again.
Engine has been absolutely bullet proof and it has seen some hard abuse.https://www.dropbox.com/s/4gmgdq0iu6y6bti/Dyno3.jpg
Full rebuild and balancing work
79.4 x 80
Ported head, modified stock valves
Havassy 272 camshaft
Havassy inlet manifold
40 DHLA carburettors, 32 mm chokes
Stock exhaust manifold, 50 mm exhaust system, 1 muffler
Lada HALL ignition with modified advance curvehttps://www.dropbox.com/s/cma2odwupoe4axk/Dyno2.jpg
Without dual carburettors, carburettor was Weber 32/36 DGV. Otherwise the same engine. Predictable loss without dual carburettors.
Of course I first had a Weber DGV and after that I put the Dellortos on.
Some measured acceleration values:
0-100 km/h 9.5 seconds
0-120 km/h 14 seconds
80-120 in third and fourt gear combined: 8 seconds
60-120 km/h in fourth gear 14 seconds
3.9:1 diff and 185/60/15 tyres.
So if you have dyno figures from your Ladas I would be really interested to see them. Also please feel free to talk about Lada engine modifying in English.
