Gain power.
Burn up Valves Bummer |
From what I understand the S cars run like 10:1 rich or something and N/A engines make best power between 12.5:1 and 13:1 AFR... danger only usually exists when approaching 14:1 under heavy load, though richer is usually safer. Situations can arise where due to intake air temp or coolant temp the optimum AFR for best power becomes dangerous with the stock timing map, but the resultant damage is usually the piston, not the exhaust valve |
S cars are in the 9.x:1 range, and it is my understanding that if you lean it out too much, combustion temperature is too high and eventually melts the exhaust valves
|
9.x:1 air fuel ratio? Wow, that is pig rich lol... or or were you referencing the static compression ratio? |
Eehhnnnnhhh (buzzer)
I was thinking compr ratio So sorry |
I think most of the S cars were 9.5:1, though with some creative swapping of parts you can arrive at something like 10.2:1 and still technically be “stock”... I think the combo is late rotating assembly with early flat faced valves that gives high compression, but can’t remember 100% since I haven’t had an S car in forever, and if I got one as a project I’d likely be wanting to Ecotec swap it... |
Thank you guys for your input, and feed back I didnt know all that good information💯. Some one mentioned about boost??...., and well how can I boost my car?? What are the steps I could take??. Thank you..
