THere's all you need to know.
Keep spewing the BS, there are lots of people on the floor laughing by now.
I guess you're really looking bad now 5-7?

So will someone clarify what the debate is about here? I thought the original post was about most static compression on pump gas?
I want to avoid the bitchfest and correcting quite a few posts that are obviousily wrong, and keep to the technical discussion.

Tell me more about this 1200 psi cylinder pressure fucktard.

Hey 5-7,
Post a link to prove you have 120,000 PSI during combustion.
Otherwise go home.
Tomorrow when I have a little time, I'll post a graph from my engine technology
book which clearly shows the combustion pressures from every degree
in the cycle.
MustangEater,
This started out as highest compression on pump gas with 100 shot of nitrous.
Then it turned into cylinder pressure before and after ignition with nitrous.
Now some idiot named 5-7 is just spilling crap about 120,000 PSI power strokes!
Wow, I wonder if top fuel cars get half that much.

Octane Combustion
C8H18 + 12.5O2 --> 8CO2 + 9H2O
for every MOLE of C8H18 (octane) burned, 8 MOLES of CO2 are produced, along with 9 Moles of H2O (which would be in vapor form). That gas produces huge pressure. The large evolution of GAS is why EXPLOSIVES do the damage they do. You ******* clueless tard. Of course, as gases EXPAND their pressure drops, but I really think gas laws are beyond the scope of your intellect.
Now let's take this into consideration. Basic ARP bolts have a tensile strength of 190000 psi. Do you ******* think that if cylinder pressures AFTER combustion were as low as 1200 psi, you'd need a bolt ANYWHERE NEAR 190000 psi tensile strength????? You could probably get by with NYLON as I said earlier. And consider this, the high end ARP bolts are 220000 psi tensile strength. If 190000 psi tensile strength bolt is STRETCHED, it means a force in excess of 190000 psi. And this happens frequently in racing motors or poorly built ones. Cylinder heads getting blown off the block, rods going through the oil pan, or pistons flying up into the cylinder head. Put it together

A Stock Cube LS1 running on pump gas with a 100 shot could run a healthy compression, it all depends on the combination. I'll try to keep this a puerile as I can for the normal LS1tech member It (the cam) would have to be a "wide" camshaft that "bleeds" off loads of cylinder pressure. Naturally aspirated it's rather simple to run 12.0:1 + on 93 octane once you start factoring in Nitrous in to a Naturally Aspirated combo it complicates things.
If it was my car I'd build the combo to run on 93 octane Naturally Aspirated and try to spray it. There is some leeway with these things, although you would have to take out some timing once you start using nitrous.

OK, so you guys spill nonsense and can't back it up, but we're supposed to
believe you.
But I can't post links from NOS, KB Pistons, etc.?
Alright little boys and girls, here's the picture I promised from my book:
Notice the left axis scale peaks at 700 PSI for a naturally aspirated engine.
You might get 1200 PSI for 100 shot of nitrous.
Now I have two credible items stating combustion pressure.
As for the 190,000 PSI tensile strength:
So , to prove you're even more of a moron, TENSILE means to stretch.
You don't use TENSILE Values on the power stroke because that would be
compressing the rod! Look it up in the dictionary.
The TENSILE stregth of the bolt is to hold the rod caps in place while
the PISTON, CONNECTING ROD, RINGS fly around at 7000 RPM!
Ever wonder how much that assembly would weigh spinning that fast?
So now I've proved even 5-7 wrong with pictures and credible links.
Are you all being one sided because I'm new? Really, this is either a really
bad joke, or 5-7 is the dumbest person on this site. ANyone who believes
this guy is a fool.

By the way 5-7, it's pretty ignorant of you to assume I don't have a physics/science/chem background.
I can take a pic of all of my College text books and degree if you like?
Here's a little lesson on crank angle since you brought that up too.
Can anyone tell me what the crank angle is when the piston is at TDC?
Use this diagram to figure it out...because 5-7 doesn't get it.

and 90* (which is the angle the piston is a TDC in a SBC, LS1) would be perpendicular force (what you are calling linear), and when you. Firing it off early might work for a 60* V6, but we use 90* V8s.

That force comes from somewhere moron. With all bolts after combustion, they are withstanding the huge, instantaneous cylinder pressures. When the piston STOPS and goes to other way, its ONLY because another cylinder is going down the cylinder and sending the other one up. Sure there is energy lost in friction etc., but it's close to the same. You missed that part about

[/QUOTE]I don't see a piston at TDC in any of your little pictures kiddo. if it where, the pink dotted line would be staight up and down. Go away inbreed. TDC is at an instant. Everything is at an instant. It's dynamics. get a graph, and you'll see it. Nice try, **** off now
#118
Did you miss the picture I posted out of my engine technology book?
Here is it again since you 're too busy trying to sound smart instead of reading
my posts and learning.
P.S. Read back a couple of posts too, you missed some good stuff.
You take the cake over Terry Vance. You make him look like a genious.

crank angle at TDC.
I just posted those for you to help your little mind out.
WHy don't you answer ANY of my questions, or provide PROOF to ANY of your
posts?
Maybe because you don't know **** and you can't find any books, or links
to verify your BS.
The ball is in your court. You haven't proved a thing...except that you're a
hopeless case.
#120
who is stupid enough to think that sb physics doesn't apply to the LS1??
the only thing this thread proved to me is that having a fast car means u know exactly jack ****.
there's a lot of BS flying around in here but i don't see any from Adrenaline. maybe that's just because i'm not blinded by owning an LS1 and just working on them.
