Man you guys are crafty! I was waiting for song approval from the artist, so only uploaded to see how it all looked. Hence no title/ description.

I'm subbed to your YouTube channel so it came up on my "what to watch" list :)

Video was awesome.

diabolical1 06-17-13 01:24 PM

funny thing happened ... I watched the video and somehow the balancing and building put me in such a trance that by the time I heard it idling, I realized my hand had naturally migrated to my pants. even funnier ... i'm not ashamed. nope. not at all. :)

Lol I have heard similar stories from others :-) And thanks guys!

David Hayes 06-17-13 03:34 PM

Damn, that thing is beautiful. Can't wait for a drive along at the Fall VIR event. I call dibs!

Makes my wimpy 3 rotor seem, well, wimpy :)

Ceylon 06-17-13 03:50 PM

Just watched that vid four times back to back - Damn that's awesome :)

RCCAZ 1 06-17-13 05:57 PM

When will we be able to hear and see something MORE than just idle?? ;) How about some "drive along" vids as your breaking her in?? :)

Nice Video BTW Logan. Excellent job on the build!

chohakai 06-17-13 07:32 PM

Great video, Logan. Man, never figured you'd go Hollywood on us... I guess you have the vanity in there somewhere.... LOL... One advice, your co-start (Matt) is a bit stiff though, I'd take him out in the remake/update videos. :D

Congrats on the project. Wish you had put in the same amount of passion and effort into my 20B porsche build though... j/k :D

Farkel 06-18-13 01:14 AM

That time lapse sequence made the assembly process look deceivingly effortless! Can't wait to see the shakedown video next :)

Lol I'm not sure I would ever call a 675rwhp turbo 20b wimpy. But thanks David, you officially have dibs on first ride along :)

Thanks! This is the response I was shooting for.

This was "part 1" which was really about the assembly. Part 2 video will be all break-in, dyno runs, and ridiculous flyby's. But I'm not sure how long until that happens, I cheated on getting it to run. Doesn't even have the oil coolers hooked up, open header no exhaust haha. When I told my dad how close it was to starting he forced me to stop hanging out at his house on fathers day and start the 4-rotor instead haha.

Thanks Fred, it was done with a cell phone, go-pro and roller skate. Low budget is a understatement lol.

Maybe it was a tease, but every joke is usually 50% true. I put in just as much passion and definitely more effort on your 20b Porsche. I remember working 28hrs straight more than few times. The 4-rotor never would be worth that physical abuse to me. My customers are worth it. To put it delicately however, I never have and probably never will, meet someone with no timeframe on completion. You had a deadline to adhere to, and a goal budget. The 4-rotor is over two years of time, and basically no budget. If I couldn't buy what I wanted, I waited until something else I had to sell, sold. Sometimes it took months to buy just one part. It was pure freedom with no second party direction or goals, just my own goals.

If someone asked us to build the exact version of my car few would WANT to afford it. Let alone wait long enough to get it finished. That is why it will most likely always remain one of a kind. But hopefully an excellent rolling business card :)

The stacking isn't very time consuming. Its the hours and hours and hours of machining, porting, tapping, filling things in with epoxy, cure times, cleaning, clearancing, etc etc. It was dry assembled about 3 times first to check part interference and bearing fit first before the final assembly. Almost no factory part was able to be used "off the shelf" in the damn thing lol. Even the front bolt would not just bolt on. Had to be machined shorter and start with a early 12a or GSL-se bolt. Dont even get me started on the e-shaft oil jets!

Next video will be fun. About to start taking donations so I can really finish it to drive!

Brent Dalton 06-18-13 05:39 AM

Awesome video Logan! Glad to you fired her up the other day! I can only imagine the joy from that first crank. Looking forward to seeing this continue to progress and some future track videos!

RotaryEvolution 06-18-13 11:31 AM

nice work Logan, all these 4 rotors coming out are pushing me to just set aside some of this work and get going on mine! i haven't even touched it in over a year.. for now i guess i will just have to put off the main work until after the move to florida.

Ahhh man, I was hoping for an academy award. Guess that will have to wait, lol.

Very true words. I'm happy with your work, yet no project is ever 100% complete 1st time around, it takes a few iterations of optimization and fine tuning, etc. The real trouble is that you're just so far away...

Thanks Brent, it was pretty exciting. Was a little scared it wouldn't sound like I wanted. But it was spot on and even better, idles like the 787b and Rx792p. My two hero's :)

Starfox07 06-19-13 01:44 PM

So the same or more power, N/A, as a Mclaren F1, but lighter. Wow. Can't wait to hear this thing on the dyno.

unwritten-dinasty 06-19-13 02:19 PM

Logan, you are a GOD man.

fbse7en 06-19-13 02:38 PM

O.M.G. *slowly removes sunglasses* This. Is. Art. MORE-MORE-MOOOORE!!

Farley 06-20-13 05:59 AM

Flat out amazing ..

dabigesii 06-20-13 12:31 PM

Wow...I'm hoping this makes 600+whp na...because if so, I might have to make this a long term goal for my car. I would miss my lovely turbo whistle and the turbo feeling though.
