Rob needs to buy a dyno. The street tuning is freaking me out.
Finally a Rob video! Been too long...
Sounds like an air-to-water intercooler is coming. I would love to see the heat exchanger integrated into the hood somehow to keep that stock look. Now that would be sick.
Dude, Rob, I'm telling you man, get rid of those push to connect fittings. They are the worst for high heat and no-leak. Push to connect fittings are not rated for "leak-free" operation. You want to use a fitting which is rated for high vacuum operation. SMC makes a KFG2 stainless fitting which is rated for vacuum. You can also go with a formed hardline AN fitting with aluminum or stainless lines if you want. But push to connect is not the way to go. I may not make high horsepower cars, I design and build industrial equipment and if we have high vacuum pressure vessels, push to connect fittings are a big no-no.
Maybe get rid of that stock intercooler and convert a new one to an interchiller, put an ac compressor from a prius or something like that and mount a condesor and get an expansion valve and make some custom lines. I think it'd be a sweet build series and I think it'd be the icing on the rx7 cake
Would be awesome to see if Isaiah could build a custom top mount style intercooler that would be able to flow enough for this turbo. Bigger core and inlets using the original mounts and a made to fit seal to the factory scoop because... why not
Who else is waiting for Robs hub dyno to arrive?
That's literally how a surge port works. Its the same way on every surge port turbo. I have no IC and twin 78mm surge port turbos with 3" piping "Y" to 4" piping and 102mm TB. It does the exact same thing. The TB is closed at idle. its going to bypass a TON of air through the port. Larger piping isn't going to change that, Its normal. It will bypass a ton of air at WOT as well. Don't get me wrong, there will be a massive pressure drop across that baby IC, but its not going to screw with your tune as its a constant. I'd look elsewhere. How much of a surge in the boost pressure is there? Could it just be the sensor signal noise? A lot of transducers will make a wavy signal and need "smoothed" in the software. -good luck!
I'm sure this will be lost in the comments but is it possible to have a cross plane 4 rotor e shaft, like a crankshaft on a r1?
Reyosuke Takahashi will be proud if you make it look like his FC in the Initial D fifth and final anime series.
YES MORE DAHM CONTENT
They make aftermarket top mount inter coolers for the FC. Re Amemiya made one, ARC made one, and a few others. May not find brand new but used for sure. You could also do an air to water cooler in the stock location for a super clean look but more fab work.
The part from @
Almost at a million subs rob, hella proud of you bro, you’ve come a long way hopefully you keep making your dreams come true
I would change out the inter cooler just for a test at least. It’s definitely kneecapping the engine for power.
I love watching you with subtitle and when you do a pull, it's says "music"
i love the FC content! its the most relatable thing to me that has to do with 7's since its actually an FC and not an FD. Please keep it going!
Might consider mangling the hood some to extend the width and height of the scoop if planning to keep the intercooler at the top, but the large flat hood will probably warp with all the welding. Maybe get the guys that built your fenders for the 4 rotor to build you one from 3d scans of the current hood and just extend the width/height of the scoop to mold in carbon fiber. Plus once they create the mold for the hood, I'm sure others with the same years would like one as well to resell more of them.
Did the booster vacuum fix also fix the weird MAP signal? If not, double check where your vacuum signal for the MAP is sourced. Back when I was a Microtec dealer and still using Haltec E6K’s on these cars I found that the vacuum ports closest to the throttle plates produced very erratic signals. I surmised it was turbulence near those ports.
I love the factory look of the intercooler. Would love to see a larger top mount that has the factory cover.
