Pettit Racing

ABSOLUTELY! Pettit Racing has been building, racing and selling rotary engines for over 20 years.

If you need a rebuild of your current engine or a complete crate motor - we can and will help.

We don't advertise these on our online store where you can add them to a cart, because they are more labor intensive and require more information then we could possibly efficiently provide.  Most engines are built as a 'two way street' - you tell us what you want, what you will use it for, what your goals are and we respond with the best course of action, materials that will be used and final cost.

For more information, check out: Pettit Racing Engines then give us a call!

Our standard street port improves efficiency and flow with out major changes in port timing, benefits are better fuel economy as well as more power delivered through all the rpm ranges and boost levels. Our standard 13btt street port engine, when properly tuned maintaining a charge temperature <125F @ 16‑20 psi/boost with a 1:1 ‑ 1:1.25 backpressure ratio is capable of producing 200+ hp / rotor. On a two-rotor engine this is 400 hp, sure these engines will make more power but then other factors like material strength and management errors become more critical and these variables can lead to unexpected failures.

Extra large and monster ports (common with older naturally aspirated and drag race engines) can compromise reliability. Since the seals, both apex and side, pass over larger openings, this allows more seal flex to occur resulting in accelerated seal wear as well as greater possibility for catastrophic failures.  All this should be especially evident when most conversations about turbo rotary engines include mention of seal failures.  More info on our engine page.

Assuming all other specs are normal,   a clogged catalytic converter would cause that problem, if the converter is good check for a restriction in the induction system.
