Mash the peddle and enjoy. The difference between the two d­evices is their source of energy. So why not look at the option of a supercharger on my NA Subie? You would think the car would've been pretty darned fast but never trapped better than 102-103mph IIRC. The air box from the turbo goes directly to the inlet of the blower and the blower is gear driven off the front accessory drive. The blower carried the engine into the 3500 RPM range at which point the turbo made enough boost that the super belt was putting power BACK into the crankshaft. has anyone ever heard of this being done? Powered by UBB.threads™ PHP Forum Software 7.5.8. As for changing over turbo to s/c, personal decision, but it be a waste due to replacing all the setup for a turbo, ie headers, up/down pipes, etc... Now if you had an NA car like i did, then its more of if your bold to build your own s/c setup or if you just want turnkey kit. Beyond this though there's not a whole lot of difference. Well, I used to own a very nicely put together VW Corrado. The problem is its alittle harder to properly do a supercharging setup. I personally think changing a WRX from Turbo to Supercharged would be awesome. :p. Cheapest method is buy an Eaton M90 on eBay for $200. Both superchargers and turbochargers do this. If the blower was somehow dropped out of the picture then the vanes ended up becoming a big restriction for the turbo to overcome. I would just study the building of superchargers and … Boost is built by pressurizing the air coming into the supercharger. I'm not sure I'd try to do a turbo-blower setup with a carb. On the Detroits there is no way to isolate the blower from the engine. I've only ever heard of a turbo feeding into a blower. Turbos are currently the de facto small-engine power booster because they efficiently run … It got to be a pretty complex system but apparently pretty impressive. Nice score on the Autorotor, do you know what size it is? sure anything could be possible. Whatever the reason GM decided to add a turbo to feed the blower it obviously worked but on the surface it seems like the induction system was more complicated than it needed to be. We offer low boost Turbo conversions for the MINI One and Cooper which are designed to bring them up to Cooper S (and more) spec. You've got to have reasonable mixture for the conditions by the time the mix gets to the cylinders - or you're in trouble. im not sure how that would work though...ideas anyone? In every turbo system there are two sides, the turbine where exhaust gases spin the impeller to speeds of over 100,000 RPM. The technology is pretty neat and has been around for years on Diesels. GM began phasing out the 2 strokes in the early 90's and introducing 4 cycle Diesels that were more emissions and electronically compliant than the 53, 71, and 92 series engines. Pretty much everything but a sophistacated ECU replacement (had a chip and was OBDI). I been in both a s/c subi (i own one) and a turbo subi (wrx), each has its own style. show me one supercharged 4 cylinder that makes more power than most turbo charged 4 cylinders. Turbos use the high temperature exhaust gas to spin a turbine which in turn rotates a compressor. If you get 30-40 hp from the conversion WHO CARES where it came from??? Most high HP supercharger applications are using methanol injection or other fuels that help get around the heat input issue. By far the biggest difference between the S and the regular version is the supercharger that the S features and that is responsible for most of its improved performance. 1.5L or larger? I know every + & - to turbo charging. another idea i have is a turbo blowing through a draw through roots blower setup. The blower continued to spin, but because it wasn't compressing anything, most of the parasitic drag. They took a toyota MR2 engine and put a turbo feeding into a blower. Anyone have experience with supercharging a BMW. That small shaft will break when pressure is applied to it. It is possible, and it has been done. Forced induction engines typically use richer mixtures because they have serious intake temperature problems. Diesel turbos only blow air, direct injection handles fuel. The extra fuel promotes more cooling of the intake charge from the vaporizing of the fuel. In the last days of the 2 stroke Detroit Diesels they used a turbo to feed the blower. A supercharger uses horsepower from the engine’s crankshaft to turn (power) the compressor while a turbo uses the energy in the engine’s exhaust gas to spin the compressor. If you run across a Detroit 6V92T or 8V92T then you've found one to look at. Forced induction refers to some way of forcing more air into the engine than would normally be drawn into it. While others at the same time were switching to turbo from the factory SC and were putting down a lot better power (and torque). now the question i have is why not use a small roots blower to help spool up a large turbo? Unlike a supercharger, a turbo has a lot more components that make up the entire system. Where the supercharger loses out is in peak power vs. a turbo (and the fact that the motors in question already have a turbo, of course). Fast! A centrifugal supercharger is a specialized type of supercharger that uses natural centrifugal energy to force additional oxygen into an engine. Hamfist told me it was only a 1l. Question, I've thought about supercharging beacause turbos are just to complicated for my taste; the problem is that superchargers are too expensive, turbos are far cheaper by comparison. We receive plenty of calls from people asking what it takes to successfully convert from either an N/A or nitrous combination to supercharged for their street car/weekend racer. i was reading some stuff on how some engines, large turbo deisels mainly, use dual turbos with the large turbo feeding into the smaller one to spool it faster. It got to be a pretty complex system but apparently pretty impressive. Replacing the Turbo with a supercharger? They took a toyota MR2 engine and put a turbo feeding into a blower. Go with a small turbo instead (it's small displacement afterall)! Higher compression engines use direct injection (where fuel is fed into the cylinder at the last moment) as this helps to avoid premature ignition issues, and has been effectively used on modern petrol engines, something they borrowed from diesels. A centrifugal supercharger looks a lot like a turbocharger on the compressor side, and that's no coincidence.
