GFORCE Transmissions PA
Myself, SpeedNYC (Roan) and 13BRx3 (Allen) took a road trip to GFORCE Tranmissions on Friday. We left there with a few goodies. Big thanks to Roan for getting all the details, talking to Mike and helping both Allen and I get our transmissions. I could have called GFORCE myself but since Roan already had a great relationship with them, he took care of it for me.
Last year I broke 3rd gear, Roan spoke to them and worked it out and since he was buying another transmission (20K total so far) and they fixed my transmission for a great deal. If you have to get GFORCE, I would suggest going through SpeedNYC (Roan) Big thanks to Mike@Gforce who rebuilt the tranny while we watched. He then gave us a tour of the facility which was huge. I really was amazed and how nice they were and the senior Mike made it a point to tell us they appreciate the rotary/import business and will support us. The rotor housings you see in the pic are in development and should be available shortly. Mike mentioned they designed these housings with the combined efforts of a select few of the top engine builders in the rotary drag racing community. These engine builders and tuners are the ones that are going to be testing the unit. The names that were mentioned have rotaries in the 6 sec/low 7 sec range all making over 1000HP.

I had a blast! Thanks everyone!!!!!!
|
I need to get on your guys level asap
|
looking good guys.
Whats the details on the housings? Whats suppose to make them better? |
You should had heard them in the car. Sounded like a party! Did you get my free one?

Awesome pics! I can't wait to hear more about there rotor housing they are making.

What's the deal with everyone's Gforce's breaking?
Also, I have never seen a rotor housing break so I don't see the need for these? The weak link are the e shafts and side plates and apex seals |

most likely the housing was cast around the sleeve so probably not. i'm sure they could try but it may deform the new sleeve on installation.
i wasn't aware the housings were a weak link either unless the twisting forces are cracking the enlarged holes for the dowels/studs. |
im guessin bigger coolant passages...

If anyone seen rotor housing design of wankel engines which were intended to be heavily turbocharged, then they would know how Mazda parts are subtle in comparsion with them. Mazda didnīt change casting strenght of production engines since 10A, they didnīt have to. But if someone is pushing 1300 HP and mainly very high torque levels, its understandable to move on to such components. Not only they will allow for even more power, but internal sealing at such levels will be better and so will be reliability. |

Apex seals and e-shafts are already covered, side plates, its different story. Their breakage at dowel land is consequence of rotor housing deformation. Dowel pins should align parts of the engine, not transfer side loads created by housing deformation to side plates.

Wow, I was there on Thursday afternoon. I got the "tour" but I'm disappointed I didn't spot the rotary parts in the workshop. It was my first time around there even though I work just 10min away. (My car doesn't have the power to need that kind of gearing)
I see you had a look at the new Ford race engine (and the Chevy labels they made for it as a gag). If you noticed some boring cast iron parts in the back room you would have seen what I was there for. |

Once billet parts become more affordable I think the rotary will take off.

The theory behind it is that a stiffer more rigid rotor housing will deflect less under power therefore putting less load on the dowel pin area of the irons.
|
tell 'em not to waste time with the air to exhaust induction ports near the exhaust.
|
|
meant the milling process they use in that area which i still see in the housing. 1 less step in machining but i guess a few less grams of weight.
|
Thanks for the virtual tour Ant. Looks like good things are happening there.

Got my transmission home and started grinding on it! It's got starter clearance now!!!
