Not that simple. The blower on a fuelie develops several atmospheres of pressure. Right away 6:1 is equivalent to 18:1. Also "Nitro" carries its own oxygen (is eXplosive). And the intake charge is as much liquid as air. Peak pressures are FAR higher than in your car. A fuelie built around a 1956 Chrysler 250HP engine would make over 1,200HP, partly from high RPM, but also by high pressure. Today's fuelies are built on custom blocks inspired by the 1966 Chrysler/Plymouth and make over 3,000HP at the end of the run. And if they run a half second too long they blow-up. Between rounds they replace pistons, conn-rods, pushrods.
It probably retards the spark, the classic way to tame knock. AND running the engine RICH is the other knock-fix. 20% rich is just a start.
The knock sensor should not be an expensive part?
And the cost to install with labor?
Also, get all the bearings and so on checked out.
Clutch / auto transmission too.
Though California has some of the toughest emission standards.
Here 91 octane standard gasoline is about US $ 1.3 a liter, and a 30 cents increase expected any time.
Diesel is only about 5 cents cheaper, if that.

The equation for power from an engine uses the average compression ratio, multiply by root 2 (1.414) to get the actual max. ratio.
Like PRR said, those are highly stressed engines, which need maintenance, so you have to consider that also when calculating running cost.
But I don't think you can drive those safely on the street, suppose a pet dog comes out of a house in front of you?
3000 HP is the kind of power needed by really big dumpers used in coal mines, and railway engines tend to be in the 3,000 to 4,000 HP class here in India.

Delhi Mumbai Fares, 1384 km:
Rajdhani Express, lowest price (air conditioned, meals included), 2960 Rupees, about US $ 40
Sleeper (no air con, just a berth), $8 or so.
Cheapest is just $5, sit where you can.
The trains are between 15 and 18 cars long, each has 64 to 72 passengers.
You can compare with your local services...

The big diesels will run at those power levels all day. A nitro dragster engine will only last seconds.
3,000HP top fuel engines are so yesterday. The most powerful cars have topped 11,000HP now. Fuel efficiency is not a concern in drag racing!
Nitro's were over 10,000 HP back in 2013 when I attended the NHRA drag racing event in Las Vegas, the year when legend John Force beat his daughter Brittany Force in the final of the nitro Funny Car event. Great to witness. What was also interesting to hear was the noise, particularly between the top alcohol dragsters and those running nitro. The alcohol dragsters rev up while the nitro dragsters go from idling to exploding off the line.
This seems to explain why nitro cars can just explode off the line, reportedly pulling 5 g's while alcohol dragster only pull 3 g's off the line.
This was extensively used in my country during WWII. You had these hideously looking cars with the gas generator as a sort of backpack or at the front bumper.

No, it's exactly ON context if you read my post:
Simplified:
I am not saying one specific thing is the reason for the increase in cost, I am saying it's an unpopular thing to do and people accept it more willingly if there is something else than can be seen as root cause. Though those things certainly make an impact, it's not the sole reason.
I am well aware of that fact, but there are other concerns that make an even bigger impact on prices and food security. The biggest problem in Norway is that the government is building a lot of roads sacrificing farm land in the process, usually it's an addition to the existing roads not despite the facts that:
1. Building more roads have never been able to reduce traffic.
2. If we are to achieve the goals in the treaties signed by a significant portion of the worlds nations to reduce climate change we absolutely MUST stop burning oil at a frantic rate merely to stroke our own egoes.
3. By removing our very limited farmland we are increasingly reliant on imports that require more traffic/transportation.
Last year Norway exported almost 15% of it's food products. So there's some space for roads ;-)

That picture of the Audi car with a gas generator is taken somewhere here in Helsinki, Finland, but I can ensure that is an extremely rare sight, at least for now and hopefully will stay so.
Regarding natural gas and crude oil prices, when the ₽ dips the trade is still nominated in $, and when any "crisis" hikes up the prices it's also in favor for certain exporters.
As of recent, March 10th, pump gas in St. Petersburg is roughly 50 ₽/liter, while here in Finland it's as in many other countries over 2€/liter.

Guildford to London Waterloo station 31 miles. Cost ~£4K/year or ~£30/return day rate. No here comes the smite - at the main station if you catch the 20 minute fast express that cost will be standing room only, packed like sardines with enough space to move your finger on your phone only. If you take the every stop that's an hour and still packed like sardines.
If you get the smaller Guildford station you always get a seat, takes an hour and still costs the same. The rub is you get less frequent trains and only on one line (without dropping into Guildford main first).
What got me was the distance/time for the commutes by the folks in the Pune office. I mean working in London it was 12 hours stepping on the train at 0730 and stepping off the train at 1930 every day, with 1-1.5hours travel. The folks in Pune were commuting 2+ hours in every day. The additional costs then impact the public service costs and make what is a game of pack-the-sardine-tin even more of a trial.
Stick to the topic, stay within the rules.For comparison: in Germany Diesel is about $2.52/liter, petrol (sorry, in Germany min ocatane is 95) $2.30/liter
Good Diesel cars need about 5 till 6 liter/100km (39...47 miles per gallon). Petrol cars about 7 till 9 liter (26...33 miles per gallon). Big V8s will be rebuilt to natural gas (gas not as petrol, I mean gas as gas) because it's much cheaper than petrol.

You can start a thread about travel in different cities.
That said, as a comparison, road transport is 4 times rail cost, and air is 10 times. In terms of energy costs.
So rail is the most efficient way to transport on land.
I have some old Reader's Digest magazines, and in one of those the DC-9 was described as an ideal commuter aircraft.
I wonder how much jet fuel was thus used.
We are still waiting, the prices here are stable, and it seems the announcement that some countries will start pumping increased quantities has caused a big drop in the spot market price of crude oil.
Like I said, it was a panic reaction by some traders, or speculation.
If you are into conspiracy theories, or not...depends!
For those curious, diesel is described as gas oil and sold by cargoes during trading on commodity exchanges.
A cargo implies a fully laden sea going tanker, a fairly large quantity, I do not have the exact value.
Sulfur levels and sometimes the cetane level are also described, and the units can be in metric tonnes or liters. But weight is the more common description.

Here the gas conversions use mostly Italian systems, it seems they are the dominant producers.
The cars have an extra gas tank fitted in the luggage area, and can use either gasoline or gas, which was LPG earlier, now mostly natural gas.
So bi-fuel cars...spark ignition engines, not diesel cars with compression ignition engines.
But there is no need to rebuild the engine, unless it is worn out.
Economy is 1.5 x petrol per kilo of natural gas to gasoline in liters.
LPG gets a 1 km / liter economy reduction, but is about 2/3 the gasoline cost, so there you save money.
A petrol fueled car which runs 20 km / liter on petrol should give 30 km per kilo of natural gas, and about 19 km per liter of LPG.
Both gases cannot be used together, the working pressures are very different.
CNG here is 450 gm / liter, sold by the kilo.
LPG is 540 - 570 gm /liter, sold by the liter.
Diesel is about 800 and gasoline about 750 gm / liter. Both sold by the liter.

Low compression is better suited for blown and super charged engines the objective is to charge the cylinders with more air charges for bigger booms.
You mean forced induction engine. Around where I am, blown engine is basically no engine. BTW, supercharged engine is forced induction engine.
EH, just ol’skool hotrod lingo 😎

but you are correct that it is one in the same as a supercharger…..just not technically so.
