What is a good static compression ratio?
Speaking of the FAA though, funny thing I have close to four things approved by the FAA for flight. I can assure you they are not as serious as you think they are.
Regardless of all this, people will always call you out cause as you just stated you have experience in EGR and stock emissions stuff. Giving advice on N20 and what not is a little out of your experience and by that nature you really should not be arguing with people who have done things only fueled with what you have read somewhere.
Anywho, this will all go over you so meh.
I did mostly Helicopters and Military/Government stuff before moving to Tucson to the commercial civilian side of things. The FAA is a joke. Pathetic IMO. The A&P means nothing in the grand scheme of things. I know many a mechanic without A&P's that would run circles around all the A&P's in my hangar. It's insane. The FAA has standards far far far below my own.

A person with actual experience (BTW, Pat (Bowtienut) logs upwards of 100 competition nitrous runs per year) will get and hold my trust/respect to a much higher degree.
Someone who has zero hands-on experience in a particular area handing out advice? Not so much.
Jus' sayin'......

You work business jets? I've not much experience with those. But, I know that those have more strict tolerances (perceptional anyway) to the books than what commercial enforces. They still don't hold a candle to the detail of helicopters. I'm entirely too **** for fixed wings. I drive my management crazy, then their bosses and QC back me up.

I'm used to paperwork taking longer than actual work. LOL. You ever done a RESET? If not, that's where every single inspection that has ever been written on an air frame is performed at the same time (it resets all scheduled maintenance inspections to the same point). We tore helicopters to the frame, cleaned and inspected everything (including opening up wiring harnesses and inspecting all wires and cleaning them all), fixed or replaced everything that was bad. Then put it all back together, ground runs, test flights, tq checks, ready for missions in 45-80 days (air frame dependent). The paperwork on those rivals the encyclopedia Britannica. Imagine doing the zero time close outs on that. It takes a day just to review the log book post RESET, and none of the actual RESET paper work goes in the log book.
For me the FAA presents test requirements that are completely overkill and customers err on the side of that cause they A) don't know otherwise B) don't want the liability. Biggest issue is passing vibration tests that test situations that will never ever occur on the frame, unless the wings have fallen off and you are plummeting. Just causes more weight and cost into product.
So far, I have never had the FAA have my stuff pulled apart, all my FAI for conformity have been flying color passes. But again, the FAA isn't as bad as people make em out to be, sadly they are more concerned with paper trail than the product meeting said print
But I digress, run a 8.1:1 SCR.

I miss those silly twirly wings! Hopefully I get back to that soon, applied for a job locally with great pay, excellent benefits, and awesome job security. Got an offer, just waiting on the back ground check...... Fingers Crossed.
The paper trail is the truth. That really is all it's about; Government control and finding out who to blame for what going wrong.
Back on topic. I thought N20 was treated like N/A for the build with the exception of ring gaps and PTW clearances. Then the tune adds fuel and pulls timing at activation? So SCR should be determined just like it would be for DCR on a cam N/A build?
But, I also have a 3600lb sled that goes 140mph, what you got son?
Because it is a interview in a way.
U sound more like AA member than a "Man-Crusher". Now u want to brag your non-emissions car and have nothing to share 'bout compression for NOx. And that derelict babbling attracts other lamebrain unemployed experts bragging again and again and again off topic. Yea someone that has to tell u how good they are means u would defiantly miss it if they didnt. Same troll now is asking for the right compression ratio science shows he really dont know poop 'bout NOx but is just here to share his butt hurt whining and whining and whining. Cant shut up a real oink head.
Yea i link and even sometimes cut and paste good information for those asking. I dont know anyone here that has done continuous objective testing of different compression ratios with different size NOx applications - other than some NOx vendors or D. Vizard. But to share that here makes some of the hacks sequel like pigs for stepping on there amateur progress. So what? They can sequel all they want - it dont change the facts or the truth.

BTW, Cardo0, I'm not unemployed (if that was what you were trying to say), I am gainfully employed with a reputable international employer with good pay and benefits. I have, however, found a better job with a better employer with better pay, benefits, and schedule locally. Why wouldn't I take it?

The Best V8 Stories One Small Block at Time
The LT1 is very similar to older SBC engines but is different.
In the 90s when I became interested in cars all the magazines and writers like Vizard were saying 185psi cranking was about the max for a street pump gas(92 octane) motor, BUT even the Caprice LT1 at 10:1 cranks higher than that and is fine on 87 octane.
You have to be a troll but the most dedicated one I have ever seen, no way a normal functional human being could be as thick as you are in the face of so many vastly more experienced posters.
U truly have some chronic mental issues and need to seek help. The topic here is compression ratio with NOx. And u have nothing but personal attacks to contribute. No useful information. U only display your mental and emotional problems by lying and lying. As i said before the blabbering derelicts here only attract more trolls and u confirm that fact.

I am merely enjoying the fellow troll, doing some quality troll work. Although in your case, I am not sure you intend to do so.
All in all, 5 star trolling cado0

Where on that page does it say specifically LT1 engines?
I highlighted where I said I was stating what I read in the 90s so you quoting a book written AFTER the things I was talking about just makes you the one the one distorting things.
I have EXPERIENCE with street/strip LT1s as in multiple with cranking compressions all the way up to 245psi. till outside the magic range you want to believe as gospel.
Vizard was for all practical purposes a magazine writer, he never was, has been or will be some great engine master, you put him up on way too high a pedestal. His books are a great introduction for the novice, some of us go further within specific applications. His experience is with a much greater range of engines than most of us, but you will find a lot of folks here who know the LT1 far better than he.

What is NOx?: NOx is the generic term for a group of highly reactive gases, all of which contain nitrogen and oxygen in varying amounts. Many of the nitrogen oxides are colorless and odorless. However, one common pollutant, nitrogen dioxide (NO2) along with particles in the air can often be seen as a reddish-brown layer over many urban areas.
Nitrogen oxides (NOX) formed during the combustion of coal are mainly nitric oxide (NO) and nitrogen dioxide (NO2), together commonly referred to as NOX. NOX formed during combustion is composed predominantly of NO (90-95%) and a lesser amount (5-10%) of NO2. A very small percentage of nitrous oxides (N2O) are also formed . The nitric oxide slowly oxidizes to nitrogen oxide in the atmosphere. However this reaction is accelerated in the presence of ozone (O3) and reactive organic compounds. Source
Cant butt hurt something that is brain dead.

That statement is as pompous as it gets - something i can expect only from u. LIke u have your own engine dyno and do development work for the major auto mfrs??? U have a bachelors in aerospace and a masters in mechanical engineering too?? The truth is u and your armature forum experts are really peons in comparison to Vizard - and ive nothing to be sorry about for saying it.
I cant decide if I'd want this cardoo guy banned or not. I mean the **** he says is just ridiculous but it is very entertaining.
And now u must be an expert here too. Another retard that thinks hes some kinda judge here and cant figure out how to use the ignore function. I guess he prefers the looney reciting a google definition of NOx. Yea, thats a real expert. He goes from explaining how good a tech he is at the "hanger" to reciting google definitions. Too bad he has to change jobs every 2 years to have real career. Maybe he prefers a career in looney space rather than aerospace. Maybe he wears a nice tight jacket to prevent him from playing with sharp objects - both him and that pompous psychopath that explains how hes an LT1 expert too.
Dang, this place is mental sanatorium - and overcrowded too

I got that message once, damn floor pan blew out! The HUD popped out of the dash just like you said!!!
