Regardless of material thickness, it has the same specific heat,
well i dont know "alot" about building super high hp engines but, i can tell you one thing, you cant change the mass of anything without changing its heat capacity. who ever this guy is, he is fucking dumb. for starters, he just stated the obvious and called it an argument. no shit one chunk of stainless will absorb the same heat per pound as another chunk whether or not it has the same mass. congratulation dunb ass, you know more than a fourth grader.
and while you'd think a thicker walled tube would dissipate temperature more, it has more mass to retain temperature as well.
and right here he clearly states that the overall heat capacity has increased, apparently blowing a hole in his own fucking argument thats really a statement that dosent apply to the argument. and since a mass dosnt retain temperature
it only retains heat. you could say, the extra mass is more resistant to a change in temperature, and sound much less retarded. the simple math in this problem says that if two masses have the same specific heat but have different weights (mass) the heat required to increase the temp of the smaller mass one degree is less than the heat required to increase the temp of the larger mass one degree. this guy has no idea what the fuck hes talking about. also, the thin shit has more relative surface area (area per unit mass) so it requires less heat input per degree of temp rise (because of the smaller mass) and it absorbs that heat more efficiently (because of more area per unit mass). this is why pipes are thick and tubes are thin because most pipe standards go back to the steam heating industry. the thicker the pipe the more resistant it is to a change in temp. most OEMs use a cast manifold for exactly this reason.
Being a chemical engineer, I'm sure Bisi could explain the thermodynamic principles behind it easily. But I doubt you, or many other people, would understand it enough for him to bother.
from wiki:
Specific heat capacity, often shortened to specific heat, is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by a unit of temperature. For example, the heat energy required to raise water’s temperature one kelvin (equal to one degree Celsius) is 4186 joules per kilogram
^seems simple enough to me^
in fact this is something any welder can tell you, (an HVAC tech could it explain thoroughly) nobody needs bisi's "advanced explanation" to understand it. if you have a 1 gallon bucket of water on a burner that set to 9 and a 3 gallon bucket of water on the same burner set to 9. it will take three times longer to boil the 3 gallon bucket even if they have the same specific heat. this numb nuts is saying it dosnt matter how much water is in the bucket, it only matters that both buckets contain water. WTF!
bisi could end all this by just posting a dyno chart but he wont because he dosnt have one. he would rather argue over trival items and try to tell people the earth is flat, and he invented the earth anyway, so "your" point of view on the subject is worthless. same reason he dosnt advertise cam specs or anything else. yes there are people who make bad cam decisions based on lift and duration only and all sort of bad information floating around about cars in general. but thats who bisi is, he dosnt care that his customers are stupid and lack mental tooling to ever be happy with his products. i've been doing this shit for awhile, nothing is ever cut and dry. all this guy realy has is his name and he just puts his name on a webb camshaft and calls it a day (fagot), and then dosent give out the timing cards WTF! besides all this, i know pipe headers dont glow anyway. unless you give it the coals with timing looking up at you for like half an hour. f1 headers glow red and they dont even have a turbo. noslo's log header was dull red but there was alot of shit wrong at the time and its not stainless.
in the 80's when they finally gave up on the offy (by "they" i mean the entire indy racing/engineering/sponsor/team manager community) it was making 800 hp from a ~2.6L DOHC inline four running at 40psi on methanol fuel. if i were bisi, i would forgive people for being sceptical, when i dont have a dyno chart and i tell them i've made a significant improvement.
and who ever the fuck mndude07;2356566 is... he should whack himself in the nuts with a rubber mallet, because this guy is nothing but a tool made from inferior genetic material.
