What do you guys make of this?

[tirwin]

I recently made my annual pilgrimage to Amelia Island for the Concours. ALWAYS a lot of fun. Really dodged a bullet this year by going before this coronavirus thing hit hard.

Anyway, I was partaking in some awesome car-watching and I stumbled (staggered?) across this company called Classic Nine Motorwerks. I don't know if the guys behind it possibly contribute here. If so, maybe they will chime in.

Personally, I had never heard of this outfit before but they had a car on display. Looks like they're trying to copy the Singer business model with their own twist. The car looks great.

I talked to one of the owners of the company and I'll be honest... he lost my interest pretty fast when he started talking money. Write them a check for $380K plus bring a tub and you can have one of their cars. So close! If they had only gone to $379,900 I would've been in.

But here is what I found really interesting and is what led me to talk to the guy.

The inspiration for the car was "what if Porsche had made a turbocharged version of the Carrera RS?" I like the concept.





I really just wanted to know about the turbo setup. Apparently, I can get the answer for $380K.

I think it's a 3.0 with a 3.2 plenum and some other bits.

There was another company at Werks Reunion that had an interesting turbocharged ITB setup. I got their brochure but I seem to have lost it. I'm trying to find out their name. Anyone see this kind of setup before?



I thing I like about both is the compact nature -- they don't require a turbo tail.

I've been thinking about going the turbo route one day. Really like the turbo + ITB setup.

Thoughts? Anyone willing to speculate on how these are set up? Anyone know if the ITB plenum from the last pic is something off the shelf or is it bespoke?

[tirwin]

Dammit. I don't know why the top two pictures are rotated 90º. If you right click and "open image in a new tab" they are turned the right way.

[Mixed76]

The info sheet says it is a 3.0 with itbs and a turbo. I see no itbs and no turbo plumbing or intercooler. Maybe that's not the model on display?

Nice concept. Can be done by the advanced hobbyist for a lot less money- already has been, hasn't it?

Second car looks like an advanced hobbyist build. Clean install. I wonder if the intercooler and fan are enough to cool the intake charge.

[tirwin]

Yea, you know I went back and went through my pics again. Maybe I messed up posting the pic but I think that is the right one based on the order and the car color. They said it was a customer’s car so maybe it was a different setup.

I did not get to talk to the people representing the 2nd car.

I’m really curious about that intake setup. Would like to hear anyone’s thoughts on how that could replicated.

[tirwin]

Ah. Figured it out. Same company did both cars.

They did, they came out with it the next year and called it a 930 :-)
(unfortunate about those new impact bumper laws that came out the same year though :-(

Yea, I know.

They did some other bespoke stuff on the car that looks nice. I think they used RS gearing ratios.

I just want to know if they fabricated some of this themselves? I'm wondering about turbocharging with an ITB setup and is this likely modifications of off-the-shelf stuff or does this look like a lot of custom fabrication?

TurboKraft does this on a regular basis.

My exact same thoughts, they even have a beautiful intercooler to tuck under that ducktail.

[full quack]

I love the COP, but what is in place of the dizzy...kinda looks like a vacuum line heading toward the BOV coming out of the top billet cover???
Curious monkeys want to know.

My guess is it’s something similar to Andrew Daraud’s solution. It’s basically using the dizzy as a sensor instead of using a toothed pulley.

I consider that a negative - why neuter the tough appearance of such a car with a prepubescent tail?!?!?!

[Rawknees'Turbo]

Also, I am a doubting Thomas about that electric fan on the intercooler (which looks to be a standard air-to-air unit, and not water/air) - no way does as much air move through it as opposed to a large intercooler, mounted farther rearward, and sitting under a tea tray - can't even be close.

Sleeper.

Wondering when you would show up.

You must’ve been out using the turbo and the meatlocker A/C to fumigate the neighborhood for COVID-19.

Unfortunately, we are in our 2nd straight week of almost continueous rain and storms (and 100% humidity when not actually raining - warm, nasty temps, too), so the fumigator has stayed home. But good idea - I bet all the unburnt fuel sent out the car's keister would do the business on COVID-19 . . . maybe I can market that shiit and become wealthy!!! Never let a crisis go to waste (just like the politicians don't!).

I bet the throttle response is wicked on that thing, but I've seen dyno numbers on it of "only" about 450hp - I say only as that number is attainable with a highly modded CIS system (just barely), and I've seen similar builds to that car with 600 plus, so I wonder what it holding it back.

I realized that I can save humanity by laying on the couch, watching TV and drinking.

THIS IS THE MOMENT I’VE BEEN PREPARING FOR MY WHOLE LIFE!!!

Back to turbocharging...

Rawknee, do you think that this intercooler would be too small even for a modest amount of boost?

Can we reverse-engineer this with some napkin math?

A NA 3.0 with EFI, ITBs and the right cams and exhaust might make, what... 240-250 HP? What kind of boost would this have to run to nearly double the HP?

Maybe that’s a microchannel intercooler.

[Ollies930]

The hp/torque graph in the second picture shows peak toque at 3500rpm and peak horsepower still climbing hard at 6500rpm, so peak probably beyond 7000rpm. I find that difficult to believe. Too much of a spread between the two. You would need variable valve timing to accomplish that. The numbers are easy to accomplish, the spread between the two is near impossible.
Just my 2 cents.

The Dude:
Oh, the usual. I bowl. Drive around. The occasional acid flashback.

[TurboKraft]

+1 the dyno looks suspiscious
First car is clearly not turbocharged, why have a Turbo placard next to it?
Second car... good first try, kudos for effort.

Clearly that is one of my favorite movies of all time. Never gets old.

If Luft happens, I'll be easy to spot in my Dude t-shirt.
