Hey everyone I fell in love with rotary engines Ever since I started racing formula Mazda open wheel cars years ago. My formula car had the 13b rotary engine. Now I am on my second 8. I have a few others. These cars must vary alot in hp from car to car. My first one seemed to have 50 hp more than any other I have drove .including the one I have now and it has a fresh motor. First one would spin wheels shifting to 2nd and would chirp into 3rd. And none of the others have came close to that power.im wondering if I just had one other those fluke engines that put out alot more from the factory.or if the tune can be changed on the one I have now with access port to obtain the same power as the first one I had. Both cars were pretty much completely stock.

 

Tell us exactly what cars, engines and state of tune you are comparing here. Your post isn't clear on the details.

 

The race car and the rx8s habe the renesis. Of course the race car was faster it was 1000lbs with 6 speed sequential. But my first 8 stock was much more powerful than the stock one I have now. I have also drove two other 8s and none seem to have the power of my first 8 . I was wondering if these cars vary in hp alot from car to car.

 

I don't believe Renesis engines - fully stock, properly maintained and in good condition - vary in HP significantly, engine to engine, any more than reciprocating engines do. I suspect what you've encountered are Renesis engines in varying degrees of mechanical health.
