Peljhan , as you are varying the timing by moving the whole disc , forward and back - this means the duration is fixed . I would start with 90* closing
as it is proven that carburation is a nightmare past this with very little extra power.
Then run the sim in 1* retarded closing sequentially.
This will give an indication of what timing suits each rpm best.
But this gives odd sets of timing ie at 90* closing you have 135* opening , so radical closing , but average opening.
Back at 80* closing you have 145* opening , so very mild closing , but very radical opening.
Again , past 145* , tuning is a nightmare - and this will not show up as bad carburation issues in the sim , as in reality.
This is why I believe Fletts servo gib system is superior , especially when operating both sides independantly.
Many 4T cars had VVT on the inlet only , and this worked well , but VVT on both cams gave a huge increase in power range.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
