Ahaha, don't know why anyone is taking that as an attack. I think this is the only info he has released:
"We thank ASP for their hard work and their friendship and support on this project.
We are using their base GT kit that is avail for $10.900 and our built engine for this project.
We are using 2.7 heads and all S4 plumming that has been ported by us from intake manifold to throttle body.
The short block was completed with rods and pistions to our spec,balanced/blue printed.
The cool charge comes from ER intercoolers with CF shrouds and Vast WMI kit. In the next few weeks we'll tune for WMI and more fine tuning for better results."

Haha, lots of people on the definsive over a "guess" of race fuel. (educated guess is still a guess) Not to be a Negative Nancy but some times we all just gotta chill out.

It would've taken less breath to say "custom pistons" than it did to tell me to search his old posts for a random spec. I appreciate you're finding it for me though.
Funny thing is if you look at my first post I didn't ask or even mention race gas. My post was asking if thicker headgaskets were used because I was curious about how those thick HG's hold up at way high boost, like this 40 psi. I wasn't even talking about knock lol. (and on a side note, I had already assumed it was race gas because it would be stupid to not use it when trying to tweak a car to the max.)

To comment on your quote above though, if you're knock limited at your current CR, it could also be seen vice versa as meaning that you're running too much boost for the gas you want to run. Or that you're running too much boost for CR you want to run. Or you're running too much timing for the boost you want to run. However you want to say it, or whatever your goals are personally it doesn't cover up the reality that these all work together and knock is a function of all of these variables.

[QUOTE=jibberjive;23778210]Look at what you quoted from me, I didn't say anything about being knock limited. I simply said CR does greatly affect knock. I'm going to assume that you're not ignorant enough or bullheaded enough to try to contend that CR has no effect on knock. I'm sure that you know as well as I and everyone else that detonation has many factors, such as gas octane rating (knock resistance) like you're saying, as well as compression ratio, AFR, timing, IAT's, and boost. These all affect knock.
This has nothing to do with ignorance. This has to do with tuning methods.
On the other hand YOU were strictly talking about CR greatly effecting knock. And I'm letting you know that this is just simply not true. All things equal, if you're gettting knock at the CR you're running you simply put together the wrong motor/setup for your application (ie. you need to run less boost if you're FI or less compression if you're NA OR run higher octane fuel). Simple as that.
It really isn't rocket science. I've tuned many cars and I know very well what can 'cause' knock like some things you've mentioned. CR simply isn't one of them.
You're just not getting it. Unless you have no idea what you're doing, you just don't build a car 'blind' and try to run a 15:1 motor on 87, or build a 11:1 20 psi motor on 94, or whatever you're trying to prove.
Fact is, you choose a CR for your application. Not the other way around.

You can edit. Just have to request it. The notice doesn't always show at the top of the forum page like it is supposed to.

Simply put, if you setup a running engine that didn't knock, kept every single one of the other variables the exact same and only adjusted the CR higher and higher, eventually it would knock. I know wikipedia isn't the end all, but just to show that you're the only one who tries to say CR isn't a factor in an engine's tendency to knock, here's a wikipedia article. Look about halfway through the 2nd paragraph under the "Abnormal detonation" heading.
http://en.wikipedia.org/wiki/Engine_knocking
Not hard to understand what I'm saying, and it really should've been just left at that first single sentence where I said, "CR does affect knock," because it's true.
If you catch yourself trying to reply to this post with something application/tuning specific such as, " But if it knocks at your CR then you chose the wrong (add your own word here)," then stop yourself and reread what I wrote, cause I'm not talking about proper methods of tuning nor any specific setup.
