Premium fuel question

[Anonymous]

I'm alittle lost when it comes to the advantages and/or disadvantages of advancing the timing and using premium fuel to alleviate knocking or predetonation. I would like to know more about this topic and thought I'd ask the professionals.

I know there is a point of depreciation when it comes to timing advancement but when? Say with a stock 200 or 250.

Yes there is a point where teh added performance may not be worth the added cost of fuel. Where that point is? Who knows?

I'd like to see dyno results of a car with 10* ADV versus 20* advance and see the power difference, and see if it is really worth it. Maybe I'll do that when I dyno my car since I can rent the bay for an hour and can play with stuff like that. hmmm...

Adding Premium isn"t always the answer. When the engine is at temp..When you give it gas, you can tell at what speeds you get a rattle sound. As you go up in faster accelerations you can fine tune your dizzy to eliminate the rattle...ZZ
