# What should the cylinder compression be?

## What should the cylinder compression be?

Healthy engines should have compression over 100 psi per cylinder, with no more than 10 percent variation between the highest and lowest readings. With a compression tester, a few hand tools, and 20 minutes, you can try this yourself.

Is 150 psi a good compression?

150 is realy good compression.

### How do I know if my VW is dual port?

It is pretty easy to tell the difference between the two. Look at the intake manifold. If the ends of the manifold where they connect to the heads are made of cast aluminum and split into two ports then you know that it is a dual port motor.

What should the compression be on a VW 1600 engine?

VW performance air cooled engines for the street can run 8.5:1, 9:1, or even 10:1. But for this engine, we want to keep it cool between 7:1 to 7.5:1. As stated, the compression ratio is effectively the difference between the “suck” volume and the “squished” volume of air inside the combustion chamber.

#### How do I know what VW engine I have?

Identification of the Volkswagen engine can by accomplished by locating the engine casting number on the engine block.

1. Locate the engine casting number. According to Bustopia, the engine casting number is located below the generator stand, which is mounted to the top of the engine.
2. Write down the casting number.

Is 90 psi a good compression?

As a general rule of thumb, compression pressure around 90psi is the minimum required for combustion to occur in a gasoline engine.

## Is 120 psi enough compression?

You should start to worry if one of your cylinders is getting close to 100 psi. Most new engines in good condition compress at around 175 psi. Suppose that #4 cylinder were at 120 psi, the difference ratio would be 31.4% which would indicate excessive wear in the cylinder.

Is 170 psi good compression?

You should start to worry if one of your cylinders is getting close to 100 psi. Most new engines in good condition compress at around 175 psi.

### Is 135 a low compression?

There is more than one school of thought on what the compression, of the average engine should be. As a general rule a compression of 135 PSI or better is excellent. Similarly, a compression of 85 PSI or lower is extremely bad. As long as the lowest reading is 100 PSI or better; then the engine is acceptable.

How many horsepower is 1600cc?

A 1600cc engine can produce 120hp at 5000rpm. The 1600cc V-twin Harley Davidsons have about 90HP while the four cylinder sport bikes have 160 HP. 1600cc engines are capable of generating more than 160hp.

#### How many horsepower does a VW 1600 have?

VW later boosted the 1,200cc engine to 40 horsepower. In the 1960s, VW went through 1,300cc and 1,500cc transition models before coming to the 1,600cc single intake port design, and then the 1,600cc dual port design at 60 horsepower, that lasted through the end of production.

What is a good compression ratio for a 1600cc engine?

Compression Ratio. Typical results of a compression test were reported to us: #1-100 psi; #2-130 psi; #3-95 psi; #4-120 psi. Someone else wrote to say, I am beginning to think my 1600cc engine may be ready to go, it seems I am getting some bearing noise, and now all of a sudden one cylinder has dropped from 127 psi to 100 psi.

## How much horsepower does a 1600cc engine have?

The initial production of the 1600 was a 1.6-L engine named Type 126. It featured a carburetor fuel system and there were several versions. This engine’s original postwar production was 1100cc, putting out just 25hp, eventually reaching the 60hp 1600cc. It would be a while before the company would add fuel injection to this vehicle.

What Octane should I use for 1500cc to 1600cc?

Same thing with changning yuour 1500 pistons and cylinders for 1600 cersions and keeping the 1500 heads – you’ll get a compressionr atio of about 8:1. Such changes require the use of a higher octane gasoline/petrol 8:1 need about 93 RON octane (89 AKI in the USA) and 8.5:1 compression ratio needs about 95 RON (91AKI in the USA).
