Hybrid 911? Anybody see this?

Ran across this over the weekend while doing a little suspension research:

Vonnen Boost For Porsche – Electrifying Performance

Looks to be a very cool concept and will be interesting to see this implemented on air cooled cars. I cringe at the price tag. Am guessing that gearboxes will need a fair amount of strengthening.

Pretty cool! Thoughts?

You may secure your waiting list position with a down-payment of $10k. Total price depends on your chosen performance level with the base package starting at $75k installed into your car, including parts and labor. Pre-order pricing will be honored for orders placed through the end of calendar 2018.

cool but pricey!

Looks like Vaporware to me. What are you going to do with stage 1 at 175hp? My old TT and my '75S have more horsepower than this. And they are old.

Except they had several running driving ones at Rennsport.

Mated to a Rothsport built ST spec 2.5. The one on the stand is a PDK and water pumper. I think they will sell more of these for Carreras and Caymans.

Hey guys, I'm happy to answer any questions about the system. We have the 991 system close to customer-ready and will be delivering 2019 Q1. And it rips.

The 175 hp in stage 1 is PLUS 175 hp. That puts a garden variety 991 into about 500 hp and a GT3 into 675 hp.

Air cooled cars will follow and will be customer-ready later in 2019. Figure the power-add to be similar.

Curious as to how many BTU's of heat is created by the MGU and how is the liquid cooling managed?

[techweenie]

With electric motors, it's more about the torque than the HP. ICE develop peak torque at 2K+ RPM. Electric motors deliver peak torque at one RPM. A company I have stock in makes powered wheels that add massive torque to cut acceleration times.

Of you're old enough to remember JATO, this is the automotive equivalent.

[Chuck Moreland]

Liquid cooling is independent of the engine cooling system. We have added two separate cooling systems, one dedicated to the battery, the other handling the MGU and controller. Both are ethylene glycol based. There are dual radiators, one dedicated to each circuit. I don't have a BTU number for you.

Chuck, I got to meet you at RRVI. Thanks for being so helpful with my questions.

This concept is one I've been hoping to see available for years. I hope to see more in the future.

How much weight does this package add and how is it distributed?

SYSTEM COMPONENTS & SPECS – Vonnen Boost For Porsche – Electrifying Performance

"Weight: Net 120 lbs (stock flywheel, starter motor removed, 12V battery replaced with lightweight unit)
The system total weight is partially offset by removed components; stock flywheel, starter motor, and 12v battery size reduction. The net system weigh is just over 100 lbs."

Distribution looks to be pretty even, with the battery in the frunk, controller in the rear and motor/generator in the center.

[Chuck Moreland]

Net weight impact is about 120lbs. We have some offsetting savings since we remove the flywheel, starter motor and go to a light weight battery (since the 12v system is not starting the engine).

Our MGU and controller sit in back, and battery module goes in the trunk. the 12v battery savings is close in location to our battery module weight. The flywheel/starter motor savings are close in location to the MGU and controller addition. All-in weight distribution moves forward slightly, but not dramatically. Filling the tank with fuel is a much bigger shift.

Saw it at Rennsport, very cool, would be a nice bump for the aircooled cars.

Chuck - Are you recommending any modifications to gearboxes to handle the increased torque?

[Chuck Moreland]

With respect to the need for trans mods, we have total control of torque delivery. This provides great flexibility with respect to the trans, CV joints, clutch etc. We can program to work with the stock trans without problems.

On the air cooled cars, there are a variety of trans options; G50, 915, 911, 901, 930 each with different torque handling capacities. We can program the system to accommodate each.

We constantly monitor a variety of inputs including gear selection, RPM, and throttle position. Our VCU combines these inputs with knowledge of the trans and engine capability to make decisions about how much torque to produce at any given time. We can limit torque to remain within the operating limits of the drive train

As a simplified example we can limit torque based on gear selection; 1st is limited to 50 ft lbs added, 2nd gets 100 ft lbs, 3rd+ let her rip, etc.

But it gets more sophisticated than that, we can torque-fill. The engine has a torque curve that climbs, then dips with RPM. We can map to add more torque when engine torque is low and less torque when engine torque is high, thus creating a flattened torque curve from idle to redline. We can set that summated flat torque curve to remain within the operating limits of the drive train, and elevate it if the trans has been modded to accommodate more.

We've been working on this concept for a few years and are very excited to be out with it publicly now.

RR was great as the coming out party for Vonnen, glad you could stop at our display.

[Hawkeye's-911T]

A buddy recently sent me these photos of a Tesla modification. There were no details attached.

Cheers

That's the E RWB car from Streetfighter LA. We provided the suspension for that car. It was just at SEMA in the Toyo display.

That is so ****** cool!
