13 compression on a modern engine aint the same 13 compression that we're used to working with on a prehistoric BP.
while I don't think mazda "beefed" up the trans for more power, I do think they're well aware that most of these cars will be driven hard through twisties and track, so I don't think it's a "glass box".
the fuel system question is a good one

If Mazda went as far with weight reduction on the gearbox as they did on the weight reductions on the rest of the chassis I could see it being a glass box. For the most part stronger trans=bigger internals=heavier box.
Who knows though. Time will tell.

Also, the bellhousing is not the same as the NC, so Fiat guys won't be able to source NC transmissions as replacements, even if it is the same internally.

Well, I am up to 1500 miles now and this car is just fantastic. However, the suspension is hilariously soft and I had to take it easy on the back roads of the hill country between Austin and San Antonio the past few days. You can feel the weight transfer from when you do absolutely anything. Accelerate and the things squats hard, hit a bump in mid corner and the whole car heaves sideways. I can't wait to get some real suspension on it. I also really need to get an LSD, because wheel spin from moderate cornering is quite annoying.
The dealer continues to be unresponsive about my top issue.

How exactly is an NC box in the Fiat, a completely different engine with no similarity to the 2.0 skyactive, of any help to someone with an ND?

Discovered something interesting and quite counter intuitive on the dyno yesterday. When doing OEM baselines we always run an OEM like tire. In the case of the ND we assumed the huge RE71R would be costing it 2-3whp. Not so. Both sets inflated to 30psi, same coolant and IAT temps at start of pull then SAE corrected. Did multiple runs in each config and the results were the same. Picked to representative pulls to display. I'm sure there is a significant aero drag components and then tire scrub when cornering but straight line rolling resistance appears to be a wash. Weird.
BTW, you can use 140whp as Dynojet SAE corrected power for the ND, heat soaked. We could cheat the number a bit on a cold engine but 140whp is real world. Goodwins dyno shows 137~138 for the baseline I think so all their numbers are conservative by that amount. Got the Goodwin header on last night. SOTP feels like at least 10whp on the stock map. Will post dyno's in a day or so.

Additional rolling resistance of the wider, softer compound tire being offset by stiffer sidewalls and higher relative pressure?
Edit- that came out wrong. I should have said that at equal pressures both tires actually make the same area of contact, might even be smaller for the 245 with the stiffer sidewalls.

Fire Truck Red ND RZ over Jet Black
Finally got around to edit and upload the gallery for the beautiful Jet Black Club that we installed our ND RZ in.
The Fire Truck Red powder coat is pretty much a dead match to the Brembo calipers, so for those who are looking to pick up a bit of color, consider this a great looking $80 option on Brembo equipped cars :thumbs:
Took this pic for those who asked about the way the side cubbies behind the seats look like post installation -
I'll upload pics of the covers in a separate post.
Enjoy!

Cosmetic covers for ND RZ installation are now available!
The covers for the ND RZ installation are now available and you can order them directly from us, just shoot me an email or call us at (818)339-3884.
They are priced at $95 plus shipping, with no charge on shipping if they are ordered with the bar.
The covers are supplied with the sticky back Velcro, ready to install in a matter of minutes -
The production covers were further optimized from the ones shown previously by cleaning up the design even further to create a more seamless look.
Installation is nearly identical other than changing the location of one small piece of Velcro on each side (moved from the top to the back of the panel).
We've been working hard to finish off the looks of the ND RZ installation to make it as factory-looking as possible.
Next on our to-do list is a ND RZ specific clear wind deflector which will double up as a great way to make the cheese grater looking OEM deflector go away
Stay tuned!
