This page is for personal, non-commercial use. The series Porsche Turbo and Turbo S will introduce themselves next year. Porsche offered a few scribes a taste of what's to come with a shotgun-seat ride in Turbo S development prototypes. The reviews so far commend Porsche for raising the bar yet again.

Power will come from a 3. Peak boost for the Turbo S is The changes add up to estimated output figures of horsepower and pound-feet of torque, according to Car and Driverwhile Automobile quotes torque at lb-ft. That's an improvement of 61 hp over the current Turbo S, and either 27 or 37 lb-ft. Shifting, as has been the case for years, is strictly automatic, an eight-speed PDK dual-clutch managing gears. The transmission housing isn't as long as before, but the unit weighs 53 pounds more than the seven-speed PDK in use at the moment.

Speaking of weight, Turbo S largesse rises by pounds overall in coupe form. Even so, Porsche estimates the 0-to mph blast will take 2. If the magazines are correct, 2. The coming Turbo S adopts staggered wheels; instead of inchers all around, the fronts will hold at 20 inches, the rears grow to 21 inches.

Those back wheels hide out under bodywork wider by 20 millimeters compared to Front brakes upgrade to the mammoth units found on the larger and much heavier Panamera E-Hybrid Turbo S and Taycan Turbo S, with piston calipers — up from six pistons — clamping All-new options for the new car will include a crackling Sport Exhaust, a Sport Performance package that tweaks the suspension and lowers the ride height 20 millimeters, and an optional carbon fiber roof for the coupe.

We still don't know exactly when the new Turbo S will debut, but the announcement is due early next year. We get it. Ads can be annoying. But ads are also how we keep the garage doors open and the lights on here at Autoblog - and keep our stories free for you and for everyone.

It only takes a few seconds. First intel arrives on Porsche Turbo S hp, lb-ft of torque, in 2. Jonathon Ramsey.Here's a comparison chart of turbo compressor wheel and turbine wheel. Not necessarily sorted by size and power.

I did not list the horsepower rating of the turbos. Some cfm listed are max flow. Others are listed at 2 pressure ratio PR or at Note: some turbos come as a bolt-on kit. Specs are not limited to the chart listed below for those none-bolt-on turbos. Disclaimer: Greddy modifies Mitsubishi turbos. Due to lack of factory data, all Greddy turbo specs here are referenced using Mitsubishi specs.

It may not be accurate. This chart is just informational, use at your own risk. G T30R. To4E Custom made to your specifics. Also, there's a 'S' version of The Pentroof kit is the regular version with 70mm inlet. The pro version uses internal wastegates. Actual CFM.

Volumetic Efficiency or VE, I will be using from this point, varies depending on temperature and pressure. The actual calculation of VE is done by ECU using measured amount of intake air, with Mass Air Sensor measuring at intake pipe or Speed Density measuring inside the intake manifold close to intake port of the engine.

Atmospheric pressure as given by average barometer reading. It can be found on all the current model years from Expect to achieve full boost with the proper mods and a quality tune between rpms. No other information known at this time. Of all the IHI models, the VF22 has the largest potential for peak horsepower, and is capable of supporting the highest boost levels.

It is capable of running up to 25 psi. The VF22 is a roller bearing turbo that utilizes the P20 exhaust housing. This housing is mated with the smaller compressor housing of the VF24 for fast response and excellent low and mid-range performance.By ReinhoudAugust 20, in Forced Induction.

Main reason to put it on the dyno was to see how the carbies were adjusted, bike was running way to lean! It had never done that before, hence, this bike weighs at least kgs. Then, a lot of words you never hear in the bible. Con rod gave up, destroyed the crank case, and one piston, valve shim came out what destroyed the rocker cover, long story short, I felt like crying Was in doubt for quite a while if I wanted to rebuild it with or without turbo, decided to rebuild it with turbo, or else it would be a waste of my previous efforts, and that turbo power, it's addictive, but the turbo riders know that.

At that time I worked at a place with a lathe and a milling machine, so I build a new bottom plate with a turbo feed pump incl. To my surprise this worked absolutely perfect, of all the trouble I had with my bike, all the handy work I did myself worked ok.

So after the crank case got destroyed I had to build everything over to the other set off crankcases I have, there was quite some difference in the 2 sets of crankcases, but now I have the 2nd set finished.

Then I got scared that clip falling off while engine was running what didn't happen before and causing havoc, and decided to play it save. Plan is to rebuild a stock crank with Katana rods, billet clutch basket and reinforced backing plate and straight cut gears, this is all very expensive, but I can't afford another time it goes wrong.

With all that it should be able to handle at least hp. I've got a bad paid job, and I'm busy fixing up my Land Rover Discovery V8so it's going to take some time before it's going again.

Bottom plate needs to be cleaned, and I want to spend some time on the oil pressure regulator, crank up the pressure a little. Very impressive and innovative! Can't say i've ever seen anyone use a bevel driven oil pump but if it works then why not! Bottom plate is 5mm thick, that "tower" is screwed in the bottom plate, and then secured with 3 M6 bolts, it's all quite sturdy. Scavenge pump is also a few mm wider as the feed pump, idea was that the wider pump moves more oil from turbo charger into sump as the feed pump moves from sump to turbo.

I had it all disconnected, feed line and scavenge line into a measuring jug, and then fire up the engine, jug stayed almost empty, all works absolutely perfect!

Brilliant, brilliant, brilliant. Cool solution and excellent engineering skills. As Maggot said, " Gold". This morning I spent some time behind my little lathe, just some improvements on the bottom plate.

The shaft driven by the extended shaft had too much clearance, also the bush in the oil pump was separate from the bush in the "tower", therefor it didn't turn smooth the first time I put all together and I had to make it all go smooth, because off that it got too much clearance, not a lot, but enough to spent some time on it. Also I had to make a spacer to get the gear at the right height, I didn't like that either, therefor I made the top bush a little bit longer so I can leave the spacer.

So, bashed the old bushes out, turn new bushes, and tap those back in, all fits and works perfect, I'm happy with it, less parts, less clearance, better alignment, and it turns more smooth. I also should send out my tax return papers so I can order the con rods. I'm looking into what sort of turbocharger to get, I had a TDG on it, that's too big, boost came in about rpm, and took another rpm to get full torque.

Since a few months I have another job, which what I earn a bit more, and for my new boss I'm working in an aluminium plant for a few months, and with this job I have about 2. Those IHIs look quite ok based on info that is floating around the net. Although difference in spooling compared to your current one might be quite small in the end. One alternative with ball bearings could be Garrett GTR.

It's about the same size than those IHIs or maybe slightly smaller. Yep, like you probably have noticed published info about those IHI turbos is quite limited. But based on what I found they are probably somewhat smaller than your current turbo. So if those are easily available they are probably quite good choice. Garrett one is most likely again slightly smaller and faster spooling than any of those IHIs. And you can get them as new for relatively reasonable money.Privacy Terms.

IHI VF22 cfm at Of all the IHI models, the VF22 has the largest potential for peak horsepower, and is capable of supporting the highest boost levels. It is capable of running up to 25 psi. The VF22 is a roller bearing turbo that utilizes the P20 exhaust housing. Expect to achieve full boost with the proper mods and a quality tune between rpms.

This housing is mated with the smaller compressor housing of the VF24 for fast response and excellent low and mid-range performance.

It does not have the same top end power of the VF22, but spools up slightly quicker. This turbo shares its compressor housing with the VF23, however, this housing is mated with a smaller P18 exhaust side.

The smaller characteristics of this turbo allow it to provide ample bottom end power and quick spool. This turbo is very popular for Imprezas with automatic transmissions and Group-N rally cars. Utilizes a thrust-bearing design and a P12 exhaust housing. Utilizes a divided thrust-bearing design and a B14 exhaust housing. Utilizes a ball-bearing design and a P18 exhaust housing.

The VF29 is nearly identical to the VF24, with the same compressor and exhaust housings. However, the compressor wheel in the VF29 has been changed slightly. The changes made to the compressor wheel in this model are generally viewed as improvements, and as such, this unit is typically chosen over the VF Has a different location for the pressure hose on the wastegate actuator.

On the exhaust side it uses a It's rated atrpm. Both the primary and secondary turbochargers use a floating metal centre bearing - not ball bearings. At idle, the turbo spins at around 20, rpm and it can go on to a maximum speed ofrpm. It has a 17mm diameter wastegate opening to bypass excess exhaust gas. Comes in at rpm. The VF34 is nearly identical to the VF30 but has improved spool up due to its roller bearing design.

It also utilizes a P18 exhaust housing. The VF35 is similar to the VF It utilizes the same compressor housing and the same compressor inducer size. The differences are in the divided thrust-bearing design and the P15 exhaust housing. This allows the VF35 to spool slightly quicker than the VF34 at the cost of less top-end performance. The VF36 is a twin-scroll turbocharger that utilizes a ball bearing design, a P25 exhaust housing, and Titanium possibly TiAl?

It is essentially a fast spooling VF The VF37 is a twin-scroll turbocharger that utilizes a thrust bearing design and a P25 exhaust housing. It can be found on all model years from The VF39 utilizes a thrust bearing design and the P15 exhaust housing. It can be found on all the current model years from It utilizes a P18 exhaust housing.The most powerful versions of the Cayenne wear the Turbo badge and are some of the most powerful and best-performing SUVs available.

As with the rest of Porsche's lineup of sports carssedansand crossoversthe Porsche Cayenne Turbo models are fast, well built, and expensive. As true Porsches, they offer luxury-car appointments combined with big power and athletic handling that defy their considerable size and weight. Two models are available, each with all-wheel drive and their own potent powertrain.

That includes the Turbo S E-Hybrid plug-in model, which packs horsepower and, on a full charge, can be driven more than 20 miles solely on the power of its electric motor and small battery pack. Porsche also offers the Cayenne Coupea sexy fastback variant of the SUV, which we review separately. Completely redesigned for the model year, the Porsche Cayenne Turbo hasn't changed much forbut the Cayenne Turbo S E-Hybrid joins the lineup. On the exterior, the Porsche's tailgate badging can now be painted with the model designation in body color, and there's a new paint color available: Cashmere Beige Metallic.

Turbos Explained

By comparison, the hp Turbo model, which can still hit 60 mph in less than four seconds, is the better value, relatively speaking. With the savings, opt for the Sport Chrono package, which adds a Sport Plus Mode for additional performance, and the Assistance package, which contains important safety features including adaptive cruise control and a surround-view camera system that gives you a degree bird's-eye view of the SUV.

It makes parking and maneuvering in tight spaces much easier. Its precise steering, adjustable air suspension, and responsive engine combine to make it feel more like a sports sedan.

And the all-wheel-drive Cayenne doesn't just handle like a vehicle half its size, it also offers a compliant ride and high refinement. It's exceedingly quick, too.

The Cayenne Turbo is powered by a hp twin-turbocharged 4. In our testing, it went from zero to 60 mph in 3. The Turbo S Hybrid's power and performance are even more extreme.

It uses the same twin-turbo V-8 from the Cayenne Turbo, but Porsche has enhanced its power with a hp electric motor sandwiched between the 4. Total output is a mind-boggling horsepower, and speeds as high as 83 mph are possible without the gas engine ever switching on.

The system also can operate in a battery-saving mode that only burns gas or the two systems can work together, and its operation is exceedingly smooth. Its battery pack can complete a full recharge in about 2.

Did we mention it can also sprint to 60 mph in 3. It's one of the quickest SUVs we've ever tested. The E-Hybrid version should provide the best fuel economy when driving around town, but the EPA hasn't released estimates for that model. The Cayenne Turbo model is rated 15 mpg city and 19 mpg highway.

We haven't subjected either Cayenne Turbo model to our highway fuel-economy test.Expect to achieve full boost with the proper mods and a quality tune between rpms. Compressor Map.

Posted 28 September - PM. Ugh i could ramble on for forking days about this stuff. Thanks mate, awesome copy and paste skillz you got there. Should we go into Aftermarket turbo's that are suited to an EJ turbo application? Posted 29 September - PM. Turbocharger Compressor Calculations John Estill Introduction The purpose of this little paper is to show the reader how to calculate the volume and mass of air moving through his engine, and how to size a turbochargers' compressor to move that quantity of air.

It should also offer some enlightenment of the effects of temperature, pressure, and intercooling on the engine's performance. Engine Volumetric Flow Equation This equation is for finding the volume of air going into the engine. The displacement on our cars is cu. We have a four stroke engine; the intake valve on a cylinder opens once every 2 revolutions of the engine. So, for every 2 revs the engine takes in cu. How many pounds of air is that?

That depends on the pressure and temperature of the air in the intake manifold. But the volume is always cu. It relates the air pressure, temperature, volume, and mass ie, pounds of air. If you know any three of these, you can calculate the fourth. What are absolute temperature and pressure? Do we care? Of course we do! Absolute pressure is the gauge pressure measured by a gauge that reads 0 when it is open to the outside air plus atmospheric pressure.
