Too much engine?

[OsoMoore]

Aside from the horror of the messed up rear bumper, what do you think of putting this much engine in a 911?

Like they say ... there's no replacement for displacement ...
I would give my neighbour's kidney just to drive that car for a day

Cheers !

Maybe too many stickers on the rear window, but definitely not too much engine.

[baq911]

I wouldn't say its too much HP if its set up correctly....which this one seems like it is.

Must look great at nite spooled up......ass on fire.

[nvnovrts]

that is filthy.

Everyone has their needs, wants & expectations in life... The problem with a lot of "our cars" is that in paper, a 2012 BMW 328 Diesel will not only give this car, but many others out there, a hard time, but which would you rather drive? It looks all right and props to the builder who should also post on the rear end thread, BUT without much of the fanfare this one has, I'd love to humble it down in a dragstrip and/or road course as well as a few other dozen cats out there, no? Mucha espuma, poco chocolate ....

Maybe this one below actually may be too much for most of us... But please keep in mind, asking "what if?' on this thread almost begs the response to be - depends on who is asking and how much can they afford, because typically, if you gotta ask, then - Bruce Canepa never heard of either one, hence this monster dwarfing just about anything that's ever seen to be street legal, including the blue one above

Description:

1989 Porsche Twin-Turbo Speedster Edited from the Porsche 911 Performance Handbook by Bruce Anderson This could be the ultimate street hot-rod: a 1989 Porsche Speedster with 935 suspension and a twin-turbo, IMSA version of the 962 engine. It was built by an old friend of mine: Bruce Canepa, of Canepa Design in Scotts Valley, California. Bruce has been involved with Porsches as a business, as a race driver, and as an enthusiast for years. Canepa Design did a lot of Porsche slantnose conversions when they were all the rage in the 1980s. Canepa developed his own slantnose in 1983, a design he felt could do as well and maybe better than the factory conversions. All of the brackets and mounting hardware for his were made of stainless steel to prevent corrosion. He converted the factory fenders, then re-zink-coated them for rust prevention. Extremely popular, Canepa conversions for were done for customers as far away as Australia. Canepa's involvement with Porsches included ownership of one of the Holbert-built 962s, which he restored and raced. The 962 had come with a spare engine. Although tired and worn out, it was a great candidate for a rebuild so Bruce set it aside for a future project. Gary Primm, a casino owner in Las Vegas, knows cars. He has a large collection and in 1989 he added a brand new Porsche Speedster. A bit disappointed with its performance, he parked it with less than 100 miles on the clock. Primm met Bruce Canepa through AMG and they talked at length about what could be done to the Speedster to both improve its looks and make it a more exciting car to drive. Canepa felt that since 911 Speedsters had the turbo-look bodywork and suspension, they should have also been turbocharged. He thought that their performance should be like a modern update of the old Carrera four-cam Speedster, a car that was great fun in its day. Canepa's idea was to scale up that sort of performance and fun to contemporary levels. Canepa had the 962 engine assembly and he knew he could turn it into an awesome street motor. He told Primm that, using an assortment of Porsche factory racing components, he would transform the Speedster into something really exciting. It would have lots of power, it would handle, and it would stop on a dime. He could also make it ride well; firm like a race car, but not so firm that it wouldn't be a delight on the street. Primm liked what he heard, and gave Canepa the green light. Originally Canepa said that he wanted the car to look stock except for a large DP (Design Plastic) rear wing. He soon realized he would need larger wheels and tires to handle the potential performance. It also became clear that the stock bodywork of the car would look unbalanced with the oversized wing. Canepa liked the looks of the 934, and so adapted some of its design characteristics in the Speedster. Canepa says the design maintains a uniquely Porsche look: competitive yet subtle, classy but, at the same time, very serious. The design uses 934 fender flares and a 934 front spoiler. The DP rear wing was chosen for the look, and because a 934 wing wouldn't cover the huge 962 intercooler. The car was also to be air conditioned, so the wing had to house the A-C condenser. The overall goal was a car that would be very, very fast, while still retaining all the creature comforts of a street Porsche. It would have at least 550 horsepower and a top speed in excess of 200 mph. Because of the potential speed, Canepa installed a low profile roll bar for safety. The roll bar is welded to a side bar structure, which in turn is tied to chassis rails that run from the rear to the front tower assembly. The stock Speedster is fairly flexible and, as a result, doesn't ride as well as it should. Canepa felt that for the suspension to work properly, the chassis needed to be rigid like a Porsche coupe. So, in addition to the roll bar and side structure, Canepa's technicians reinforced the chassis by boxing the rockers and raising the floor level behind the seats, effectively creating a monocoque substructure. The result is an incredibly stiff tub. The only other way to achieve this kind of rigidity, says Canepa, would have been to weld a roof on the car. Originally the plan was to use coil-over suspension, but during the planning stages another customer had Canepa build a Porsche Club car that was to see double duty on the track and on the street. After much testing of coil-over spring rates they found a solution that, in theory, worked well. In reality, today's real-life highways aren't very smooth and the car rode horribly. When the spring rate was softened for street use, the track handling suffered. As a result, a torsion bar suspension was chosen for the Speedster. Torsion bars provide a good ride on all pavement surfaces, plus they'll let you take a corner as fast as your fear level allows. Canepa used rifle-drilled torsion bars from Stevens Machining, 23mm in front, 33mm in the rear. 22mm "Charlie Bar" sway bars from Wrightwood Racing are also used, along with custom-valved shock absorbers from Bilstein. 935 center-lock hubs and nuts were used so the Speedster could run center-lock wheels. BBS had just developed a wheel to handle the side loads of the new GTP cars. Cleaner-looking with thicker spokes, it was ideal for the Speedster. The 17 inch BBS-GTP wheels are 9 1-2 inches wide up front, 12 3-4” wide in back, with 275-40 ZR17 and 315-35 ZR17 Goodyear GS-C tires. For brakes, Canepa mounted 935 rotors to the 935 hubs. Calipers are the big 959-style Brembos. In order to combine the streetabiliy of power brakes with the stopping power of a race car, Canepa designers fabricated a power brake vacuum storage tank using the 962 engine as the vacuum source. Canepa says that the Speedster handles better than any street Porsche he's ever driven. He says that with racing slicks it would handle as well as his RSR. It has a great ride too, as smooth as a new Carrera on all the road surfaces on which it was tested. Jerry Woods got the nod to build the 962 engine. Canepa wanted a lot of torque, a lot of bottom end power, and as little lag as possible so it would be manageable on the street. That's exactly what Jerry delivered. He converted the 962 to 3.3 liters by using 100 mm pistons and a 70.4 mm stroke crankshaft. He chose an HKS electronic wastegate control, designed a proprietary programmable twin ignition system, and added a prototype Haltech fuel injection management system that's designed to take full advantage of the 962's twin sets of staged fuel injectors. It runs on one set when normally aspirated, then kicks in the second when the engine comes up onto boost. The result is enjoyable operation around town, and absolutely stunning acceleration and performance on the open road. Upon completion, the Woods-built motor delivered 581 hp at 6500 RPM at 1.1 Bar boost. Peak torque was 550 lb-ft at 4000 RPM. (On 110 octane fuel and 1.3 bar boost, the motor delivered 650 hp). Installing it in the Speedster presented its own set of Inquire

No such thing as too much and at least it is a Porsche engine.

[Laneco]

You can never have too much engine.

Your suspension can be lacking, your brakes in need of an upgrade, and (in my case) your driving skills inadequate, but you can NEVER have too much engine.

angela

p.s. - take the time to read the build info on the blue car. It is brilliant.

[ToddM]

But what the hell is it built for?

It would just up it a class where it would NEVER be competitive on the track and it surely isn't street legal.

I see **** like this all the time, these goofy cars built with no apparent reason or purpose other than some boner somebody has that week.

[sc_rufctr]

Lots spent on that one... But this killed it for me.

[Dan J]

Very interesting build. Unique approach from a non traditional Porsche builder
I like it alot

Time attack, open class lapping, the owner's fun...all good reasons for the owner to spend his or her money however they like.

[ToddM]

They can do whatever they want, I guess I don't get it (not that I was invited nor care to be invited).

When you want to build a car for a specific purpose, the right platform needs to first be selected.

[SAY - 642]

Video ...It's cool..... but a twin turbo air cooled, would be the Ultimate Porsche Porn!

But would not mind taking it out, for a spin

Regarding too much...I think beauty lies in the eye of the beholder.

What about the smugglers box just hanging there open with hoses running in and out of it but the battery is not in the smugglers box where it belongs?

I see he comes from a line of go-straight-fast builds which I could care less about which are uncharacteristic of Porsche. i see very little written about the suspension.

This whole no-purpose build is just to showcase Bisimoto parts. I liken this to hand-waving and showboating typical of Apple which people stand in long lines overnight for.

Is it just me or does the idle sound high?

Subtle? Really?
