That is very cool!!!!!!!!

 

Yeah it's cool but take a close look at the intake right infront of the throttlebody. They state that it is a 13b turbo but I've never seen a filter infront of the throttlebody on a turbo motor also where's the turbo. Cracked me up when I saw it in the magazine the other day. Also has a Cadillac grill on it. Thing is still badass.

 

another place where rotaries might be banned????????

 

that looks like a turbo intake/motor minus the turbo

 

Rotary mills have been providing high-performance reliability on the racetrack for years. They provide a high horsepower-to-weight ratio, can be tuned for lightening fast throttle response, and when appropriately built, will spin to higher RPM than any piston engine. As less weight and more ponies are always a priority, the high power-to-weight ratio of using a rotary beckoned consideration. It was only a matter of time before one ended up in a competition rock buggy.

high performance reliability on the racetrack for years...................... hahaha

 

thats actually the once place rotaries rock is on the track. They are very reliable for track motors

 

How about a 4 port Renesis in a rock crawler.

Very Cool! Both of them!

 

Jake's crawler was in the Nov issue of RX Tuner as well ... very cool stuff!

 

Jake's crawler is turbo now ... at the time these pics were taken obviously, and when we did the story in RX Tuner, it was NA.

 

My brother inlaw has a Samurai and I keep telling him to put a 13B in it hopefully seeing this one will twist his arm alittle. His Samurai does great it's lifted has 31in tires and it creaps and crawls over alot of things just doesn't have enough power. He has the 1600cc motor in it with the 1300cc head, I believe those are the sizes, but it just doesn't move all that great. Especially because it's his tow vehicle for his quad when he goes out to the desert. He has to beat the hell out of the motor when he's going through the mountains. But it does great climbing over rocks and duning.

 

thats prety cool, im not used to seeing 3 exhaust pipes off of a 2 rotor, i was confused for a sec, then i remembered, ahhh yes, Side port exhaust.

 

I was definately confused for a second about the 3 pipes on the header like 88t2romad. Took me a second to remember that the rx-8 has the side exhause ports.

 

what about "will spin to a higher RPM than any piston engine"? HAHA, what about F1 engines?

 

Well, that first crawler isnt turbo at all. So Im guessing either they put the turbo on afterwards or its a heavily modified n/a.

And as for reving higher than any piston engines, remember those 1.8l motors that honda builds or built, that were found in integras and civics.. some have a redline of about 9-10k and the s2000 also have a high redline..

 

Oh sweet, I've wanted to see a rotary go off raod for a while now. Those crawlers are awesome.

 

I'm plannin a Samurai Rotary swap. But I gotta get my 7 first. Afterwards I'm gonna put a REW into the FC and the NA from the FC into the Samurai. But I'm gonna supercharge the engine once it goes in. Then maybe I will finally get a little more fun outta that Sami.

 

I almost put a rotary in my Yota before I built the engine for it. I was really close, lol. A guy I wheel with that runs a 6 port 13B in a truggy he has.

I do not understand why you are laughing at that, it is true. High performance rotaries on the racetrack are reliable. Very true indeed.

 

There are a ton of guys out here in the desert who have rotary powered sandrails. Bad ***.

 

Time to be the devils advocate

The output shaft (where rpm is measured) spins at 3x the rotor speed. That way you get one revolution per ignition event, per rotor. So, a Rotary spinning at 9K is really just 3K rotor wise.

 

Somehow I don't think the fact that F1 engines go to 19k has any baring on what he's talking about.

Rotaries have an absolutely awsome record at racetracks.

 

Jake and I have been tuning it last weekend and will be doing more very
soon. It is turbo charged now. The last one was supposed to be also but
the frame was designed around an NA engine first and then Jake bought
the turbo engine from me later.
The final drive ratio is 180 - 1. It goes to 10 psi of boost and you can be
walking beside it. It is an automatic with a torque converter lock out
solinoid installed. Jake can spool it up and then let the trans lock up
and start smoking all 4 tires!! It is really a mind bender!!

You are correct in your thinking!
