Hey jacob

1. splitter is ultra high density poly ethylene, the front is mounted to the core support crash beam directly with tension rods, the sides are mounted to the canards, and are braced from underneith with L brackets to the backside of the frame area behind the oil coolers. The back side has huge spacers/with m8 bolts that run through the sway bar braces.

2. water to air intercooler is integrated into the intake manifold, that why it appears as if it has no intercooler. This keeps pressure drop extraordarily low and also does not allow any of the metal post intercooler to heatsoak as there's no charge piping post intercooler


the tank in the rear of the car hold 2 gallons of water, theres a heat exchanger in the nose and two behind each seat. I see no change in IAT temp on boost, or at stop lights, when i have the pump on. Though I haven't run more than 8psi, not past 5k rpm under WOT.


The car doesn't have any specific purpose, just concepts/ideas put to work. Hopefully it can do some track time, but definitely not going to be hardcore racing it. That's for the next one
Thanks man!

 

interesting. i am very curious how well it works on the dyno from low rpm to redline at full throttle/boost, or several full throttle/boost gear runs.

-you say there are coolers to cool the water for the system (which i assume are conventional air liquid coolers) but i'm wondering: if outside air is cooling the water for the system, and that air-cooled water is cooling your intake air, is that any better than the outside air directly cooling the intake air? i understand that water can pull heat away from aluminum much better than air can, but if the heat is just being transferred into the water that's being cooled by air, how much better a job could it do?

i have never been a fan of these, mostly due to added complexity (i'm an outspoked proponent of simplicity for car/project stuff) but i am genuinely curious how well it performs at full tilt. i am wondering if the complexity is worth it when VMICs matched with cold and intakes have produced very good results on run-ragged track cars on this forum.

also, disclaimer: i'm definitely not trying to be a sarcastic dick here; my interest is piqued because you're doing such a unique, large investment project.

 

The theory of why water-based intercooling works well is because the water absorbs the charge heat better and so allows for efficient cooling with a smaller expansion area for the intake. The coolers for the water can be as big as you like without any effect on the intake charge. You're correct in thinking that heat requires a certain amount of air cooling either way but water allows you to "out-source" the necessary air cooling away from needing a large intercooler volume.

 

Well this weekend was absolutely one of the most fun weekends on my life. Nothing like cruising to a car show with your best friends.

Car did phenomenal. Drove 3 hrs both ways, not a single hiccup, not even a single hiccup. Averaged 13 mph, better than my 3 rotor, who would have thought !? At one point, we were stuck in stop/go traffic from construction work, sitting in 80F weather for 45mins. Coolant temps never surpassed 205f! Just so thrilled. We didn't use much throttle/boost, but intake temps never exceeded 110F with the intercooler pump engaged, even sitting fore long periods.

And to the few who kept up with the "pport is going to be awful on the street". hahaha try again

The import alliance event was fantastic. Met so many badass people. Will definitely be coming back!

Now...to see if we're crazy enough to drive it to California for SevenStock

 

Hah! You might have a high tolerance for the pport compared to some others. How'd the fuel cavitation issue hold up? See you kept the cooler.
Any vids? More media of this beast, please!

 

 

Seemed fine to me man! Ended up using only 1 fuel pump, having had both wired up to independent manual switches in fear of one failing. The cooler definitely definitely definitely helped. Surge tank and lines/pump, even the rails, cool to the touch.

 

Glad to hear everything went well! That fuel economy ain't half bad, either.

 

Love the new pics. Droll!

Great to hear that the drive was a success!!

Nothing is better than building up a car, sorting any issues then enjoying it!

Problem is, if you like me you'll want to build another soon. #buildjunkie

How many miles you have on the motor now?

-Dave.

 

Thanks guys!

Here's one more that a FB friend posted


Time to get back to work. Diff brace, trans brace, check over everything, book flight for the best of the best, Nelson Siverio and burn some tires!

 

Amazing build! A couple of my friends drove up to the show last weekend and got some pictures and videos of your car, I wish I could have been there to see it in person. I totally agree with your decision to keep the FD body lines, to me they can't be beat. Glad to see someone not cutting corners on a build and get it done so quickly.

 

Thank you again to everyone who has contributed and supported this build and all of the builds on this forum. Every build has its ups and downs. We all experience struggles where things don't go as expected. Budget stress, part fitment issues, timeline issues, personal mistakes, misinformation, vendor issues, etc. Anytime you push your personal limits, there will be rough patches. The build threads help us to remain motivated. To see that other's have been through the same, but manage to push through. I know there are so many cars over the past decade that help me to stay dedicated to ignore negativity. To stay focused on ideas and goals and to make decisions without fear. Threads like bewtew's 1bad20b. Chris Carlisis's 3 rotor build. David Hayes 20b swap. etc etc Car's that started out from scratch, went through the rough patches, and pushed through to successful driving vehicles, all over this forum.


Just want to say how great rx7club has been for the past decade.

Glad to help in any way. Mostly, it's "don't do what I have done" that is of most value.

 

And, despite that he still encountered some similar problems wrt the oil pump and manifold design from a well regarded shop.
Now we see the violence inherent in the system. We're being repressed.

 

Good to see everything running perfectly! Congrats! That fuel economy is actually better than stock when you consider that you have 100% more displacement and running the same gearing. Best my stock fd ever got was 26mpg hwy. All things being equal plus 2 more rotors cuts that economy in half. What A/F are you running under cruise? Not to mention, you have more drag and a heavier car and still managed that. Glad you're actually driving this thing like that. Now you need a highway gear.

Oh yea, if you actually drive it to sevenstock, we should link up along the way and meet the Arizona crew since you'll be driving on I-20. We can make some sweat 3 and 4 rotor noise on the way there.

 

Trey..... it's I-10 from AZ to Fontana, CA and it would be SWEET, no sweat.

Zach, would love to see you make SSXX in November, but if you do, I hope you trailer, not drive it. It's a long *** ride and **** happens along the way. You've got too much invested at this point. JMO. Hope to see you in November!

 

Definitely set on making. I will try my absolute hardest to do whatever it takes getting the car ready etc to make it. Def will trailer it but wouldn't mind taking it out for a few hrs of cruise time. It would just exceptionally be badass to all meet up in person and cruise!!!

 

Trying to talk Stickman into going too! Just saw some vids of this 3 rotor destroying the dyno with Nelson tuning. He's out in AZ too. RCCAZ do you two know each other?

 

Your right but for me, it starts with I-20 and merges over.

 

The IA show is just awesome. Great atmosphere, no elitist attitude, All down to earth people, who love working on their cars. Its cool to be around people who share the same insanity.

Want to thank them for showcasing the car in their vid. Would like to make the summer meet, but we now may have some totally insane things on the pipeline

Thanks for following as always guys. A few connections have been made and now huge huge things coming soon in the coming weeks/months for this year! Can't wait to keep updating, have to wait and see

 

 

Sick pic!
