Go back and read that article again, if the thing ignites at BDC, it's preignition, a wholly different thing than detonation...
As for a Diesel, you are confusing spark ignition with heat of compression ignition.
A diesel has NO fuel in the compression chamber before the point of Ignition. Ignition happens when you take 17:1 compressed air at a heat of around 600F+, and spray in your fuel. Which ignites from the heat present, and burns from there.
Spark ignited engines, on the other hand are compressing a fuel/air combustible mixture. And the more dispersed the fuel/air is, the easier it is ignited and the faster it will burn.
If you think it will burn better compressed, think about it like this:
When Sherman went through the South, the first thing he did was find the local flour mill. He sent his men to get sacks of flour, and take them to the rooftops of the buildings along the main street, where they would cut them open and flay the flour out into the air to waft down to earth. They would then chuck one stick of dynamite into the middle of the street amid the flour-fog, and BOOM! The entire main street was efficiently dispacthed.
Now, stick a single stick of dynamite in the middle of 50 sacks of flour and set it off and see what it does. (Not Much...)
That's a rough equivalent of the piston at BDC with a combustible mixture present, and the piston at 37 degrees before TDC with a compressed, combustible mixture present.
It's the pressure trace of Preignition that will get you. You can see when it starts burning, and as it burns it expands---sure, it's burning slooooowly, that's why it's usually silent. This expansion happens while the space for the expansion is getting mechanically smaller. It's why they call it the silent killer. Think of it as hypertension for your car. Detonation is when the expanding gasses are rapidly burning, faster than the piston is going down (expanding) and that pressure spikes. While it's a pressure spike, the volume available for expansion is expanding...far less potentially damaging than preignition when the space is mechanically decreasing.

Trailing airhose? HARDLY!
Use a SCUBA Tank!
80 Cubic Feet of air---enough for one minute of operation of one of the 4HP Chainsaws with a high-flow two-stage regulator and 8 Bar requirement...
Heck, you can even get em in aluminum so the smaller homicidal mainiacs can move into disembowelment via power tools as well!
******************************
As for the S.C. Redneck comment, there is a visual image that comes to mind of the corpulent good-old boy that doesn't move that fast...
What I was getting at is two guys that fit that visual discription, and who were relegated to 'light duty' because of on-the-job injuries got more done in a day that a crew of 22 did here in three!
Appearances can be decieving. Work ethic has a lot to do with it, sit on your hands long enough and you start to crave getting something anything accomplished.
Those guys had been pushing mops and brooms around (millwrights) for over a month when I got them assigned to me because of some scheduling difficulties.
Frankly, given the way they worked, I think we could have gotten the whole thing done in four days had they been 100%!
Though I will admit, it DID take them 24 hours (that's three 8 hour days, guys!) to change the oil in the machine...300 gallons.
Now, I guess 24 hours spent on oil changes in 20+ years of running really only works out to less than one hour a year on oil changes...but I would have preferred that it all didn't have to occur when I was at the jobsite! LOL
They wanted to 'make the job last' when it became apparent that the work wasn't that strenuous, and it was WAY better to be in yoru dickies and twisting a wrench slowly than acting like some ersatz janitor to fill a slot because you're on restricted duty...
And since I was on a special rate for the job...I was not too quick about lighting a fire under them at the time.
I guess I got some redneck in me, too! LOL

If I was viewing this in California...
The black helicopters would be circling by the time I typed this!
I think even looking a Supressor Porn is against some law there.
My kid was SO disapointed when the .50 Cal ban went into effect. We had picked out a 'build it yourself' kit (The Grizzly) that we were going to do together as a father-son-scouting project.
So much for that...
Ahhh, a Class 3 State.
If only you guys had decent weather. You already got the Packers. Give Madison to Iowa, and I'd make it a consideration for residence! LOL
Argh! I knew I should have never clicked on that link...

Yeah, just saw on the news the national price is dropping from 6000 to 5500 rupiah a litre. So that means it's dropped to 20,790 a gallon...and the IdR to US$ exchange rate is now 12,956, so that means $1.60 a gallon for Super 95 Octane. (refigure earlier post of mine, I was using the old Rupiyah I bought here in 2005. The exchange rate is now much better!)

No side grip?
Loose the Leather Mask Ak?

"The new phone book is here! The new phone book is here!"
I highly doubt I have to look to see if what I took to MSA made their pages...LOL

"8 posts does not a member make"
Participant, maybe.
Member? Hardly.
Sorry about your situation. For $65 you can get the harness from DIYAutotune, the sensors in the stock datsun work fine, and the later MS units have software that lets you set the data pairs so there really is no need to change to 'gm' sensors.
Check out the MS forum here, lots of information there.

Powder coating will withstand solvents far better than the 500F Rattle Can stuff will...
I am in the habit of solvent spraying the engine when oil gets on it, my only reason for mentioning it.
Powdercoating is cheap when you consider clear annodizing...though you can check out Caswell Plating.com and see what one of their smaller '5 gallon bucket' setups goes for, I'm sure there's all sorts of little doo-dads you can think of to clear anodize once you have the kit at the house, and the car all apart...

So, what about that Y40?
-
I used to own a Valiant Charger with a 4.3L straight six, ... , but second you went round a corner would lean out terribly and car would always stutter and stop...........
They did not solve that on the Volare's as well... my wife's 7X Volare would ALWAYS stall when I drove it around a left corner...
She drove it slower, so no problem I guess. But everytime I stepped on it to turn left across traffic the damn thing died on me.
And that was a one or two barrel carb. Terrible positioning of float bowl or something. 15 years down the road, and still the same symptom.
That's progress, eh?
Back to your regular programming.

Now question is, which do you prefer... White or Pink?
There is an answer for that question, but I'm not saying it...
-
Same as my buddy Drew. He snagged I don't know how many 3-53 Detroit Blowers with all these grand plans on using them on this project or that.
That was in 1985...
They still sit in their boxes, oiled and fresh. Likely they will never be used.
At least you're being realistic! LOL
E-Bay is your friend!

Is there a photo that accompanies that story Palmetto?
When they made the announcement at Tonawanda earlier this year my buddy was told 'dress nice today, and meet us at 1030 for a meeting'
Ended up they wanted him on the podium during the announcement to the local press!
He was not comfortable in that role...LOL
-
yes, too bad they have a test at all!
now they even outlawed the sale of new two stroke lawn equipment.
so we, the american public, who pays these politicians salaries have them do nothing but bother us and take our money while factories, The Main Cause Of Air Polution, in the united states get to spew forth their toxic venom into our air and rivers and drinking water.
I always wondered what kind of a person would sell out the planet they live on.
on a positive note I had a non-original gas cap and the smog tech told me he could have failed me because its not part of the oem emissions set up.
I told him he shoulda mentioned that before he took my money 3 times
Ohh, you may want to edit part of that...
As for cats not helping pass smog, they won't if your car isn't running right. There are tests in the FSM to test the thing, and to test the O2 sensor feedback loop.
With the feedback loop properly functioning, no vacuum leaks, and an engine in good tune, you don't need the catalytic converter to pass to 1981 specifications. My 73 passed to 83 standards with AIR injection, headers, and SU's.
The catalyst is there to handle 'excursions' where the engine goes out of the cleanest runnign range. There is some scrubbing done at all times, but when the car is cruising on the road at speeds above about 1500 rpms, and below 3300rpms it's on that O2 feedback loop and polluting the least.
As for replacement cats...a $90 cat will last you maybe a year. Chances are good it will fail again in two years for one of two reasons:
1) the aftermarket cat has taken a dump
2) whatever poisioned your original equipment cat (other than 250K+ miles) likely will burn this one up too. Usually a rich mixture from someone playing with the AFM.
New catalysts from OEM's have a lifespan of 10 years and 100K miles by statute.
Replacement catalysts have no such standards. If you are paying $90 for it, you are paying LESS than what a scrap yard will pay you for your old OEM Catalyst.
That should tell you something about how much more catalyzing metal there is in OEM units compared to aftermarket offerings.
Let me guess, the guy that did the work 'tossed your old cat away so you wouldn't have to deal with it' right? What a great guy!
He just made $100 to $150 on your catalyst, on top of what you paid him for his aftermarket installation.

BIG turbine splitline bolts on a bullgang is one thing.
Not having an impact to zip zip zip those 1/2-13 bolts and other small fasteners all over the water piping.
4 3/8" 2000 ft-lbs bolts yeah, that's one thing.
But man! Give a brother a break!

It's beeeeeeen a while, but the Detroits were set up for clockwise, or counterclockwise configuration. The blower could be on either side depending on configuration of the package. That means the blower would be set up using a 'universal' drive package. It looks symmetrical, either direction of mounting...
The diesel blowers are not the same as what you get in aftermarket kits. You can use them, but there are modifications you have to do, and several conversions change the end casings...

The new modular diesle slated for production at Tonawanda Engine Facility for 2010?
My bud ran their CDA Facility, big plans for that engine.
Same place that made the Corvair Engine... Don't know how that bodes for GM Tonawanda... LOL

3 to 8.6 Bar inlet pressure...depends on application
I would surmise a minimum of 14 to 100+ CFM for operation, depending on horsepower.
Besides cutting up hogs, cutting in mines for timbering, and cutting downed trees underwater are two uses for an air-powered saw. But I never used them in that capacity. Only splittin' hawgs....
-
Got Dimensions? I thought the 6-71's had 3 sections in it, a 4-71 might be the one you have. A 3-71 and 2-71 do not have the bridge section with sub-webbing in them.
Length will tell you which it is.
With no frame of reference it's hard to make a definate call.
Rotor Diameter would distinguish it between the 71 and the 53 series.
Actually, a 3 or 4-53 blower would work pretty nicely on our L-Engines...

Pressure drop is a function of pressure and flow present, guys. Temperature drops as work is accomplished, wether the air is 10* or 1000*...it's the premise on which most commercial air separation plants function.
"JeffP is running his turbo off the map to make what he is making and it isn't making 500 rwhp at 18 psi."

To use Nisstune on an L-6 EFI you have to upgrade the ECU to at least a Z31 ECU with appropriate wiring modifications.
If you wan't coil on plug, then there are other ECUs that can be adapted to the L-6 as well to use a Nissan ECU and harness.

It's worked for me in the past, so with all due respect to Sgt Castillo, I'll stick with what's worked in the past for me...
And nobody said anything about walking around the house. That will get you dead sure as crossing the third rail to take a nap on the Tube...

hint: if there is very little of something, it's very valuable.
Not true. By that simple maxim, a verifiable US-Market 260Z should be more valuable that many other models of S30. They're not...
There are plenty of things out there that were one or two-of's and aren't worth squat.
If someone places value on it, then it becomes valuable.
Simply being one-of-a-kind does not impart value in and of itself.
There are other factors that build into it's value.
I could go political in recent events for more recent flagrant examples...but it's a no-no!

Thet thar be fer splittin' hawgs richt dern da middle 'o 'em!
I would kill for an I-R Titanium 1/2" Drive impact on this jobsite.
Sure, you can put 22 guys on a machine, all swinging hammers and slugging wrenches.
But for pipe flanges??? It took a full week here to do what I have goeetn done with two semi-disabled South Carolina Rednecks and an impact in a day (no disrespect, they were guys that 'could be spared' at the plant there, and they were happy to be working...and with a couple of impacts they really didn't need both hands!
Anyone working for Schlumberger?

I'm sure the guys running the equipment may have another idea about who is 'running' the site, but it's always that way!
Yes, sitting behind the computer all day is not for some people...
That is for sure!
US Army Corps of Engineers. USAF. US Navy. Take you pick. And millions is only the beginning. Heck, you can be in charge of mulit-million dollar pieces of equipment within 8-10 months of graduating high school if you go the route of uncle sugar! If that was you goal, I could have saved you a couple grand on tuition and books. The lab fees would be substituted for beer.
:tongue:
