Why do we need to compare to understand this? Don't pure methanol cars not even require intercoolers?

Add it in and measure temps. If temps aren't good, then adjust the fluid and or flow

Enquiring minds want to know if the Dragon cherry was finally popped … :suspect:

I know 😃

DGRR... the GOAT weekend!
 

Indeed sir, cherry popped, mind blown! The 15-hour drive home from DGRR afforded lots of reflection on the DGRR:

• What a fantastic community of enthusiasts and friends. To the person: generous, engaging, and just good people. Personally, the highlight was hanging with (many decades old) friends from across the country... and meeting some awesome new friends. My oldest friend, Dale Clark, set me up with getting to know a house full of new friends (hey, Steven Stephen, and Stevie, Tito, Jim, and the gang). Breaking bread, helping each other out, talking shop, and driving like Valkeries... rotary Valhalla!
• The Dragon is just simply epic. Of the many roads and tracks I've driven, it's as technical and well-designed as any. The ubiquitous guardrail-less cliff dropoffs add to the spiciness of the drive!! Again, on the drive back, I was thinking how similar to an autocross with sheer rock walls and dropoff cliffs medians in lieu of cones it was. Nowhere to put down any real power, so 2nd and 3rd gear predominate. Oh, but the banking and flow... sublime!!
• The collective events and their cars were humbling. Pick your poison, 12A, 13B, 20B, 26B, and swaps... they were present in awesome packs. Phil Sohn put together a master class in planning and rotary appreciation!
• Finally, the Spic Racer ran like a scorched cat... well, a wiper-less cat in the rain. Especially since the first two days of driving the Dragon and the Skyway required wipers and a snorkel. I had none. Add to that a Weldon fuel pump running at max blast (awaiting PWM tuning) that required earplugs for every drive, new Kumho V730 that are known to be below-average rain tires, and it was a "big boy experience". As a very well-known (and now proven intrepid) member of this Forum said, when he asked to ride with me on the first day, it was "an authentic ride"!!
• Perhaps the only regret of the weekend was that I missed introducing myself to Mr. Coleman. The whirlwind of people and events distracted me from the first meeting. Hopefully, next time Howard...
• All and all, clearly the Greatest of All Time weekends for me!

Yes... so many fill-up I stopped closing the fuel lid! ;)

Great seeing you again and awesome seeing the car alive and kicking ass!

And, yes, that Weldon fuel pump....it goes to 11!

Dale

Congrats Carlos!
Happy to see this car driving again

I've really got to try to do DGRR next year!

Awesome Time!!
 

Its was funny, Stevie made the comment as were idling behind you at a stop light " Dad, Carlos's fuel pump is louder than your exhaust" :nod:



Man, it was awesome meeting you Bro!
A true pleasure to hang out and chat about rotaries, tuning and military life stories.
Look forward to seeing ya at another great DGRR in the future https://www.rx7club.com/images/smilies/icon_tup.gif




Steve

We'd love to have you, Pete!

Carlos, how's the car doing after you got home? Or is it still locked in the garage until you come down from Rotary Overdose Weekend?

Dale

@estevan62274 Sir, the pleasure was ALL mine. Now I can't wait to see you and Stevie next year in the 20B! Regarding everyone's favorite Air Raid Siren (i.e. Weldon pump), I tested it at idle with only 20% duty cycle, and it remarkably almost sounded like a normal pump. Tuning the fuel pressure PID for the pump will be at the top of my priorities once I get Shane's attention.

Dale, thank you again for your invaluable "Rotary Sherpa" help and for introducing me to such an incredible group of good guys! And yes, the FD has sat since the DGRR rotary as a result of rotary satiation. However, I've started pestering Shane to help me finish the tuning. We've got E50 start-up and idle, initial launch and traction control maps, and the aforementioned fuel pump PWM setup before we get back to the Alamo dyno. The only outstanding decision is whether I'll swap out the ancient GT40 (67 lbs/min) to an upgraded GTX40 (82 lbs/min), a relatively simple super-core swap before the dyno.

Pete, words fail me (an exceedingly rare phenomenon) in describing how eric DGRR is. I assure you, you'll have the best car time of your life. ''nuf said!

Of course the BIG mod I'm wondering about is....

Wipers? :)

LOVE YA BUDDY

Dale

Wipers.... we don't need not sinkin wipers...
just just need to good faster!! :cool:

For what its worth... I also took the wipers off my car lol

DGRR isn't cheap. Just ask Dale about his single turbo covet, or the jewel that Crispy "Smaug" is letting me "steal" from his Mazdaspeed horde.

Nice! I have that MS bar on my car, bought it back when it wasn't a big deal :). Also have the REAR bar.....

And the 8374 kit just got ordered....damn that was one expensive trip!

Had to share the post to the RX-7 Facebook group I shared with Carlos yesterday..... :)

That's Carlos' car with the racing stripes. Good times!

Dale

Carlos, I can’t seem to find any information on what side alternator mount you’re using?
.

Thanks for the flashback Mr Clark. I see myself and my accomplice, Dean Colver, shooting shit in the background. Gotta admit I still get warm and fuzzy when I see the stripes. Good times

Team, unfortunately/fortunately, the alternator location was a custom design that a certain Brembo Chief Engineer came up with before he sold the car as a roller to me. It does sit nice and low, doesn't it!

I almost guessed it right; figured it to be a Rohan design, making it just as impossible to find …
.

Things that make you go, "Hmmmm"?!
 

I asked Klotz tech support which premix they recommended in my application...

<Carlos> "Which Klotz pre-mix do you recommend for a E50 fueled 13B rotary turbo engine? The fuel may sit in the tank up to a month at a time. Many thanks, Carlos"

<Jeff @ Klotz> "Carlos, I would recommend our Uplon Fuel Lube (KL-107)."

Gonna have to give this a bit more thought.

I was using an upper lube in addition to Redline premix, was never sure enough to try running upper lube alone

been leaning towards the new Bio-Rotary premix, just wish there was more feedback than the promoted promoter, the few people running it here seem satisfied to date though.
.

I suppose the question is; how much do you use oz/gal if using it as a straight up premix? Because as a top lube the 1/2 oz/gal recommendation is fairly standard. I was using that in addition to 1 oz/gal of Redline premix

which btw the standard Redline premix is rated for up to E50. For higher ethanol levels they recommend switching to their alcohol specific premix.
.

That was also my first thought, though I would consider a slightly higher rate. I'll need to delve a little further before I trust my minty engine to this new alchemy,

Hell ya bro! Love it!!
but where’s the wipers button? :D
