Sometimes its better to cut losses and move on. What goes around comes around.

Should have stayed 3 rotor? You should have finished your 3 rotor

 

yes sir, chip is a god

 

Anyway, for some positives,

All in all, we did well. Assembled a car from ground up, paint/body, wiring, engine, tuning etc in under 1.5 years and drove the nuts off of it at 900hp. A few hiccups in the process, but well expected considering there's only been a handful of peripheral ported turbo cars and very little data.

Now for a little motivation for the week. We will come back, utilizing everything that can be learned from the past, and with this dinosaur-eater monstrosity, shoot for 1200rwhp at 20psi

Engine should hopefully be completed in next few weeks. Internal oil pump will be deleted and trap doors will be added to the pan, so only the external pump will be required. Oil pressure will be increased another 10psi. Walker Morgan will be modifying the manifold to fit Gary (our new name for the turbo). New exhaust, and debating mechanical fuel pump for 1k+ on e85.

Pro tip:

talk less, work more and maybe you'll finish

 

 

You really are amusing

 

David,
Sorry to hear about that, but as you said, better to know now and be able to resolve things without needing an all new engine.

Keep us updated!!

Thank you Robin! All is part of the game of building, just excited to get to work on rx7s haha. Hopefully we meet again soon !

 

Thank you to everyone who has supported this buid from day 1. Everything happens for a reason and for every set back there's an opportunity to look at bright side and go bigger and better. The push continues. The same process from the beginning. Thanks again

 

DeLaHuerta? Tell him Al Sickenger says "hi". So sorry for muddying up the thread.

 

So are you going to fix your Instagram name then? nick_20b should now be Half_A_Rx8.

David, keep hustlin' brother. You're an inspiration to so many of us and have put EVERYTHING into this build while asking nothing in return.

 

^ "While asking for nothing in return"....

What is one supposed to ask for when building their own car?

Is building a car the same thing as being a fire fighter or something?

 

Well if you are building an RX7.... You should really be a firefighter...

 

lol its funny, all the saltiest one's in here, are the same folks who cant seem to finish their projects. Keep amusing us please

 

Sent the oil pump off today to peterson to have direct drive 3/8 hex installed on the rear.

Talking with Weldon, Waterman, and Aeromotive to find the perfect fitting pump for the application.

The things are incredible. I didn't want to run one before, just because I never figured we'd need this much fuel. But the BSFC of this engine is almost 0.85 and with e85 it will easily be over 1.0. The smallest aeromotive mechanical flows over 9 gallons per minute at 5k (when its half speed of crank shaft). Thats over 360 gallons per hour! 1, 363 liters per hour. Yes One-thousand, three hundred and sixty three liters per hour at 100psi!! Thats f*ck all fuel

Plan is to set this thing up for e85 and 30psi

 

Another shot of the small turbo

 

 

 

finally figured out where the oil was coming from above the crank pulley lol

 

Few pics from the tear down. Housings and irons and etc don't look too bad. But you can see from the markings/scratching on the rotors and irons that the have been contacting the plates. I'm glad we caught this now and not later which would eventually have required alot more work. Thankfully the bearings/e-shaft look good.

Housings are now off to Chip Ursu for his new badass witchcraft

Rotational assembly will be on the way soon for clearance, lightening, and balancing so that this contact doesn't happen again.

He's also measuring the crank shaft. Reportedly there was no end-play on the dial gauge when the motor was torn down. And there's reports that some of these cranks may have issues with lobe angle. Getting it checked to be sure. Triple-check everything, and take no one's word on anything when you're messing with this kind of intricacy and cost

Shout out to Zachariah Richardson, Zebbi King Turner, CLR, Chip Ursu, and Abel Ibbirah for the suggestions and helping steer this in the right direction. And thanks to everyone in here.

and once again to all the pretenders and haters please comment, we love you

 

To celebrate being the first time needing to rebuild a rotary engine in 10 years, we will reward the new engine with this turbo.

 

Question from the uneducated here, what is the bolt and connector above the spark plug on one of the pictures?

 

 

That's a knock sensor. Super important to have here... One per rotor ideally.
