Westfield rotary engine applications - new for 2016

[manik]

For all of you who couldn't make it to the Westfield factory open day this past weekend. Some interesting engine options in the new year including a 120BHP rotary which will be mated to the Mazda gearboxes.

 

 

 

and the new Honda S2000 throttle body kit:

Any info on weight, size and cost? Can two of them be paired. There should be plenty of room in the engine compartment for two or maybe three of them.

I'm looking forward to more details on the Omex/Honda throttle bodies with some dyno numbers.

Not many details just yet, but the company is working with Westfield for a customized product.

I really like Wankel engines. [insert story here on the US Navy paying me to design a Mazda rotary installation that ran underwater with 100% EGR] I had the engine out of my Lotus Elan for overhaul, and while the engine bay was empty, I dangled a Mazda 12A rotary in there with thoughts of converting it. Nah, I decided to leave the Lotus as a real Lotus. It would have fit nicely except for the exhaust ports running straight into the chassis.

 

Looks like that's not a problem with the Westfield. I hope it's a success in the marketplace. Tom, did they say how much it weighs?

I currently owned 1993 RX-7 and owned 3 of them over the years. Rotary is not for novice to take care.

Mazda started the rotary for over a decade now and still plenty of ills -- mostly in sealing issue, heat, gas guzzler, emission compliance & the volatility of the apex seal.

It's a wonderful engine. but I will not touch it if the Westfield rotary was developed by someone other than Mazda. I don't know how much experience this builder in the rotary technology.

The Mazda is experienced enough to the rotary engine but i'm still doubtful. Only for the people enough knowledge on this system.

Mine is for sale by the way.....

Agree with BusaNostra. 58lbs core weight without flywheel bell housing and accessory drive. That and a tbo of 500 hrs makes the Mazda rotary that's in mine look good. It is a directed toward the aviation market. Rotaries are not for the faint of heart but do produce a lot of power for weight and size/shape.

I thought that 500hr recommended refresh period was unbelievable. At least for a street car. A 120HP single rotor, N/A Wankel? Doable, but for drivability, and durability, I'll stick with the Mazda built version. By the time the starter, alternator, water pump, oil sump and pump, intake ass'y, etc. are added, that cute little engine won't look so simple IMO.

I don't disagree with your assessment. And I think Busa is pretty much right on target with his comments as well.

 

However there is another way to look at it. 500Hrs in a street car driven at 60MPH = 30k miles. For me that's about 7 years worth of street driving.

 

And in track terms, assuming 2-4Hrs time per track day, that same 500Hrs works out to 125-250 events. Again, not so bad. Especially compared to a serious BDD. A good friend of mine says that he figures the one in his sports racer is only good for 30-40Hrs per refresh if run to 9k RPM. And the 2.0L Porsche flat six in his other car is good for 200Hrs. So, in his case, the Porsche engined car is cheaper to operate than the Ford based Cosworth inline 4.

 

Just some food for thought on a different perspective.
