Hey RK,
1. I know you did the maths and agree with me, that's why you changed he subject to tuning carbs. What if carbs are already tuned and tuned alike 15-30hp as you stated, for engines that are commonly built between 400-600hp, like in our cobras represents 5% +/- of their power. Correct?
How can you argue that 5% is insignificant, yet argue that 5% of your car's weight is?
2. Nah, reliability was never raised by the builders, unless I missed it. Show me please. It was only raised by third parties who seemingly misinterpreted what the builders were saying. True?
3. You first raised the rule of 3s. Pat just explained the reason for your observations. Yes?
Now, just so i don't get confused buddy, please just answer "yes" or "no" next to each point. Then you can elaborate on your reasoning  |
1. Now there's a new hypothetical, with the carb already dyno-tuned and re-jetted. How about a new hypothetical, let's run a Cobra with and without the passenger seat and with a racing seat in place of the standard driver's seat? And also with the driver at his or her current weight and after losing 25 lbs?
As I said, they're (power increase and weight reduction) not mutually exclusive. Also, I never said 125 lbs or 5.5% was significant, what I did say was that if you choose cast iron, then the buyer would have felt that 125 lbs was not "meaningful."
2. Although I didn't just say builders, both builders and consumers have mentioned potential reliability issues with alloy blocks, whether it's a casting flaw or not. And cast iron blocks have casting flaws too, didn't I hear there were issues with the blocks coming out of South Korea or something? The expansion, contraction, etc. allegedly causes reliability issues that none of us (roughly a dozen on this thread) with alloy blocks have actually experienced.
Reliability issues from builders:

3. As I said, I only pointed out the anomaly of folks mentioned things in 3's, like Patrick, I was not one that spoke in 3's.
