Mazda RX7 13b rotary engine compression test
This is a quick compression test of a rebuildable core. Rotary engines are
a lot like two strokes. They will not start below 75 psi compression, this
one seemingly has normal 100 plus psi. compression with no liquid in the
chambers. This particular engine is rated at 137 hp. and roughly 100ft lbs.
torque. Pretty amazing power output for such a small package. I personally
would take this engine apart and rebuild it as it has roughly 80K miles on
it. It ran fine but smoked on startup. A few people have commented that I
should take the out the schrader check valve out of the compression tester
for a more accurate reading. I may just do that and put up a new video.
MAZDA RX7 Rotary Engine Failures
MAZDA RX7 Rotary Engine Failures
MAZDA RX7 rotary engines are strong and displace a lot of power for their
size. Traditionally, carbon deposits and heat are their biggest enemies.
Rotary engines run with a huge temperature differential, meaning that one
side of the engine runs cooler that the combustion side (side with the park
plugs). As a rule, cooling system damage should be avoided at all costs.
Learn how these issues affect rotary engines and what kind of damage is
done to them when they really fail.

what we find when the engine with 51,000 miles is pulled.

PS: I admit I didn't hold the camera stable enough for the first day of
footage. Gave me a damn headache editing the footage.

Redline Review: 2015 Mazda CX-5
No longer just a re-badge Ford, Mazda starts from scratch and builds us a
compact SUV with the soul of a Miata. The 2015 CX-5 has all the traditional
strengths: a roomy cabin, good fuel efficiency, an excellent driving
position, and good cargo space. Only a lack of an upgrade engine and
slightly dated cabin tech keep it from being the best in the segment.
