Holy Sh*t...thats nice! I want one!

 

i want two, nice

 

Nice car... god damn.... Where did you get those guages?

 

Thanks, we designed and created the Tach in house. Because we use an Electromotive Tec3r, we are able to configure the tach output to 1 pulse per revolution making the original 8,000 RPM Position equal to 16,000 RPM. The backplate for the tach was created here @ MPS and then sent out for high resolution printing on translucent paper for backlighting.

 

Jesus! At what RPM is your power peak? What size turbo are you using? Was the driver smoking during the pass? What a bad ***

 

BEAUTIFUL

Thank god you put that into an FC!

 

Nice to see a crazy rotary car in canada!!!

 

Good gawd, that doesn't even sound like a rotary when you were driving. Almost sounded like an F1 machine. I'd be afraid to drive that.

 

GOOD GOD!!!a

 

Holy $hit!! Thats Is Totally Awesome!!!!

 

Holy crap, you have my dream car!! Your neighbors must hate you guys. haha.

 

So. . . . We need more details on this car. Those videos are crazy.

 

wow!!!!!!! thats all i can say is wow

 

Have you guys finished tuning? Care to share any numbers, nudge nuge, wink wink, know what I mean?

 

NICE! love the sound!

 

thats totally sick!
i give u probs it does sound like a formula 1 car..i cant wait to hear the specs on this baby

 

The car made 708 RWHP at 5500 RPM and 13 lbs boost using 93 octane gas. This is a real street car running pump gas. This engine is a 20B Peripheral Port Turbo with custom MPS flatside throttles and MPS eccentric shaft. This combination has a powerband that really bites above 7500 RPM and continues to well past 11,000 RPM. We will keep you posted with the high RPM numbers, where the motor really comes to life.

 

Impressive, I am happy to see someone making a street car with a Peripheral Port Turbo.

What is the benefit of the rectangular port then the traditional circle?

 

Do you plan on producing these ecentric shafts for the public. I was wanting to build my own 20b and this might (might) be a more affordable way.

On the ports I am talking out of my ***, but I believe the more square port allows for more aggresive porting. Like a cam on a piston engine I have always looked at the width of the port to be like the cams lift.....the height of the port as the cams duratioin.....and the curvature of the port as the slope of the cams lob as to which it reaches its peak lift. So a square shaped port would be a very aggresive slop that reaches peak "lift" very quickly, and a curved port is like a gradual rise to the peak lift. I hope that made sense.

 

I think I've seen this car driving through the drive-through at the coffee shop a few times...

 

+1 on the Holy **** factor...

Do you guys have to rebuild it... like daily??? and on the dyno, i thought i saw it idle good... whats that thing idle at? How hard was it to PP the housings???

 

Jeez, that pass on the street was the craziest thing I've every heard or seen! AWESOME

 

that thing is sweet.......!

 

Lmao.. > 11000 rpm. It sounds perfect.. gotta love 20bs.

Absolutely ridiculous, and I love it.
