How much psi should a rotary engine have?
Continuous low cranking compression pulses strongly suggest the failure of at least two apex seal, corner seal and/or side seal sets. Note: Race engines (peripheral or bridge port) generally have a normal compression pressure of 90-120 PSI. All other parameters are the same.
How much is a rotary compression test?
The average cost for an Engine Compression Test is between $88 and $111 but can vary from car to car.
How to do a compression test-RX-7?
1. Warm up engine to operating temperature, then allow it to cool for 10 minutes while you get the plugs out. 2. Remove the front and rear trailing (upper) spark plugs while the engine cools. 3. Disconnect the circuit opening relay, and the igniter connector.
Which is the best compression tester for rotary engines?
24 months of development and in house testing have resulted in the most powerful, highest resolution handheld compression tester in the market place. Providing accurate and repeatable compression readings on all rotary engines from 10A through to the latest Renesis 13B.
How do you do a compression test on a car?
You can use the top spark plug hole (easiest to get to and there is no difference between top of bottom values). You need a special rotary compression tester allowing you to measure the difference between the 3 rotors. The test should be done on a warm engine and you should get above 200 rpm from the starter motor.
Can you do a compression test on a Renesis 10A?
Providing accurate and repeatable compression readings on all rotary engines from 10A through to the latest Renesis 13B. Whether you are a DIY’er or a Professional our plug and play design and proprietry electronics, firmware and sensor allow you to complete a multi chamber compression test.

What should I look for in a compression test?
You should watch for 3 bounces of the needle (once for each rotor face). Specifications vary depending on the brand of shop manual. I’ve gone by 7.0 kgf/cm2 or 100 psi minimum @ 250 rpm as stated in my 93 RX-7 Workshop Manual. Other references say 6.0 kgf/cm2.
