Has the car changed colors a couple of times?

Wider fenders F/R but embarrassingly narrow tire widths?

Agree that the tire widths chosen, especially in the rear, are a bit too narrow. They need to be wider to nail the rear look down.

No. The first car was a mule to gauge public reception. It had fibre glass bodywork, standard rear hatch, 5spd box, standard engine, standard suspension with the new wheels spaced out and finally a non working HVAC.

What you are seeing in the current TG video is an actual fully functional prototype with all the right bits and pieces.

Getting a 110kg weight loss on a road going car with all the modern day comforts is an amazing achievement.

Add the 6spd box with closely spaced ratios and this car will be a rocket-ship compared to even a 5spd GTS with GT cams…
Alex, do you have any insight on whether they will offer engine parts such as the intake to the public?

He talked a lot about re-engineering the plenum. When that came up I immediately thought of the thread here where someone was analyzing the plenum airflow dynamics and concluding that it was the limiting factor for 928 performance, and hence created their own high flow plenum. It's an ancient thread but I am sure it's still here. I would bet that Nardone found it when they were planning the project and focused on the plenum to increase the performance.

I believe that was Phil Threshie, IIRC.

It was allegedly a pretty rough piece when it was finally obtained by another 928er.

While I’m not a huge fan of the lights either, I don’t hate them. The thing is, this build is about a modern interpretation of the 928; how it might have evolved. Had the builders just stuck a pair of H4s on it, it would simply be an 80s/90s 928 with a few interesting twists. The headlights are a part of the modern package, and therefore necessary as they are. That’s how many headlights have evolved. That’s my take anyway.

Yep, the Threshie carbon fiber intake. Any resemblance between the Threshie intake and the Nardone intake is probably responsible for the big peak horsepower bumps that both of them provide:

It is cool that a lot of interesting work was going on back in the day. The big difference was it wasn't well funded back then and most of the time the products were not always well vetted before being sold to other 928ers. And other times they weren't finished.

This Nardone 928 seems to be a very well funded project from the results. Hoping that enough buyers come forward to to keep this series going to bring some interest back to the 928 model.

Cheers.

No, it was a 16v project. Carl's, in fact. The point of it wasn't the solution, but the fluid dynamics study that showed what the problem was. And I don't think the problem was limited to 16v motors since the original question (IIRC) was "why does the 4cyl 944 motor (the 928 motor sliced down the center) put out so much more power per liter than the 928 motor itself?".

Here is what he came up with, perhaps a failed project. But again the most interesting part was the analysis of the problem, not the particular solution.

Look at belgiumberrys 16 V with the webers, 60 hp more than the CIS Euro S with stock intake.
Doing ITB on a Euro S would be interesting.

It's all up in the air - I was told they have 11 cars spoken for and that some parts will be available to the public such as the suspension, wheels and others yet to be determined. The plenum would be nice indeed as it is a bolt on and will release a lot of horse power... I need to check the spacing on my Maserati plenum runners - wonder if something can be bastardised from a used unit? It flows enough air to make up to 530Hp out of a 4.7 so there is enough on the table there...

I'm guessing the reason for the lower power output is because they elected to run the 5-speed, and then modified it to be a 6-speed. The 5-speed is perfectly fine for stock-ish power, but the strokers were blowing them up.

I think it would have been awesome if they had instead fitted a modern 8-speed automatic to the car.

For clarification on the headlights, retaining the teardrop shape when up, as well as the 'frog eyes' lens covers, but using modern bulbs would have really solidified the 928's iconic look from the front. I'm just nit-picking, but would have been a nice touch.

I agree with the comments regarding the wheels/tires, too small - the rear rim should be 11" with 315's. The fronts 10" with at least 265's. They would give the car an even more muscular stance.

Everytime I look at the Nardone, I smile on the inside, and keep liking it more and more - it is truly a beauty!

Not sure why they decided the 928 5-speed was what should be used. Could have pretty easily copied using the Corvette X06 6-speed transmission kit that 928 Motorsports created but done it cleaner and that trans would hold more power. There's nothing super great about a 928 5-speed trans even when working like new with the heavy synchros and the gear ratios will all need to be changed for it to be a good fit for an engine with HP bump. Even at the 350 HP my supercharged 79 puts out, the Z06 trans changed the whole character of the car and being able to run 85 mph in 6th at 2,000 rpm instead of 3,400 rpm is pretty nice.

Out Greg's clutch in with a Z06 trans and he'd be all set.
