I use the 2 softest light silver springs,if it comes in to quickly after that[any sign of detonation] I use one blue instead of one silver,i leave the stop as it is on N/A engines

i just changed the springs and took the car for a ride.
what a difference that two little springs can make,it is like another engine.
everything seems to be all right no detonation.
but i wonder how detonation sounds,is it something that you hear really good.
and when do you normally hear it high in the revs?

Excellent now you can enjoy it ;D

detonation,it normally occurs at lower rpm in a taller gear,like 1500 to 200rpm in 4th if the advance comes in to early with alot of load on the engine,it sounds like a knocking, a little like a diesel engine,how much total advance do you have now? any detonation higher up would be to much total advance or if its lean,the rate the advance comes in[changing the springs] doesnt affect this

cheers richie

Hey Richie,

i do enjoy it just have to drive it a bit more now to get some confidence in it.
no sounds like that just that IDA sound.
the total advance is 30 degres now.
i think i'm quite safe with 9.0-1 compression and 98 octane fuel.
