In previous Mario Karts, I haven't had any trouble getting the turbo boost at the beginning of the race. But I can't seem to figure it out in Mario Kart 7 - how do I time the gas to get the starting boost?
The way I do the boost, is when the 2 almost stops spinning, hold the A button. Then, when the 1 stops spinning, release and immediately repress the A button. This makes sure your kart doesn't overheat and explode. If you time it right, you will get the largest possible boost at the beginning of the race. I have perfected it over many years.
A small go-kart with a 10-horsepower lawn mower engine is plenty of fun. Professional racing karts with 250cc engines make around 50 ponies and can top 100 mph in just a few seconds. This particular kart has a 1,340cc engine from a Suzuki Hayabusa, which is assisted by not one but two turbochargers. It makes 800 hp, which is enough to officially call this Batmoblie-looking monstrosity batshit crazy.
The build comes to us from Snail TV on YouTube, and the video starts with it shooting flames on the dyno. As far as opening scenes go, that's tough to beat. But hearing this thing under throttle later on is pretty good, too. In between we get a rundown of the broken parts resulting from the session, presented casually as if this was a basic Toyota Corolla rebuild. We can respect that.
The main problem is with the kart's axle. Apparently, 800 hp is "ripping" things up. Watching the clip, it becomes clear that something isn't right as the boost comes on. The dyno runs start at the five-minute mark in the video, but the really sketchy stuff comes in around seven minutes. The rear wheel is all over the place as the revs come up, at which point things are shut down. The axle was shearing a keyway in the hub, literally tearing it apart. Yikes.
Such is the price for obscene horsepower. Aside from the pair of turbos, the Hayabusa engine is dialed in for high-octane fuel and carries enough electronic gear to launch a spaceship. It also carries air tanks for an air shifter kit, and to get the rear tires out far enough for dyno testing, wheel spacers are installed. Those won't stay in place for the race track, but we kinda dig the widebody look.
I'm building a crf450 gokart turbo. I already made some thing turbo manifold downpipe welder the coolant temp sensor for the microsquirt. I was at first going to turbo charge my crf511 motor but changed my mind. I'm going to keep that motor as is. It has a ported head that I ported 1mm oversized valves springs and retainers. I have a 100mm cylinder works big bore and hotrod +3mm crank. I also have a 13.5 to 1 co piston but it's about 14 to 1 because the longer stroke.it also has a stage 3 hotcams in it the exhaust I custom made it myself. The turbo motor will have a stock stroke hotrods crank with the 11.2 to 1 piston stage 3 cam port job valves it will be fuel injected via a microsquirt. I wanted to keep the stock bore so the cylinder could be stronger. Anyway here are some pics. I need to take a new one with the crf511 in it. I also made the motor mount myself.
Why do people always assume that things are going to blow up. In Puerto Rico they drag race gy6 honda clone motors some turbo some nitrous. You need to know how much you can push a motor. How to tune a motor where to make it stronger at. Yes things happen and you can blow anything up. But how many motors you think John force blew up. Sometimes you have to blow things up to see what went went wrong and were to make it stronger at. Main thing is you can't be scared to go fast.
Nothing to do with your tuning ability etc. Just a matter of adding boost to an already high strung motor and trying to push 100hp from .45L. eventually something is going to give. Could go 200 passes just fine. Could go 10 and snap a rod. Was just wondering about the safety factor and if the nhra had Any conditions of a scatter shield between engine and driver or similar
These 450s already blow up often enough just by themselves. You're worried about the cylinder strength, but the rod/crank/piston are the real weak links here. When a 450 chucks a rod at 11,000 RPM, it makes a big mess.
No one is saying you shouldn't go ahead with the project, as it looks fun. They're just suggesting that you're going to want a piece of metal separating you from the engine in case it does blow. The last thing you want is to be sprayed with burning oil and chunks of metal while you're screaming along at over 100 kph.
That can happen but this can happen to no risk no reward. Just ordered another crf450 motor m only going to do the head work to it and throw 6psi at it. Yo also have to remember those guys are also throwing over 20psi of boost threw those motors. I'm going to start at 6psi and work my way up. I'm also thinking about installing a knock sensor on the motor and setup some fail safes on the ems.
This brand new VZ21 turbo is perfect for your high performance project. It has a rotatable center section that makes it easy to mount on most applications, it is ideal for turbocharging your Go Kart, Murray Briggs, Snowmobiles, Scooter, Quad, Motorcycle ATV, UTV, Dirt Bike, Briggs and Stratton, Lawn Mower, Dune Buggy, Small cars, etc. Built in wastegate allows you to attain boost pressures up to 15+ psi.
190-1000cc
To perform a Mini-Turbo in Mario Kart Tour, hold a drift until you see blue sparks appear under your kart. Once you see those sparks, lift your finger off the screen to receive a brief boost known as a Mini-Turbo.
We should define what that means. A turbocharger is a fan that is rotated by the exhaust pressure. It is actually an exhaust turbine, that is why they call it a turbo charger. It is a turbine on the exhaust. The turbine that runs off of the exhaust spins a compressor called an impeller, and the impeller compresses the air into the intake manifold.
There is a limit to how much pressure you can actually stuff into an engine. I have seen that some racers will stuff 24-PSI which is basically close to being double atmospheric into an engine, but typically the most that you can get out of a turbo charger is going to be around 5 psi to 8 psi.
The other thing too is that especially on a small engine like a 5 horsepower or even like a 10 horsepower you are going to taxed. You are going to be asking a lot of that little engine to get that impeller to spin up and go; so you may not get a whole lot pressure out of it to start. Additionally you are going to have some serious turbo lag to start with.
I have considered some ways to enhance a particular turbo which would be to put an after-burner of sorts where you would crank up the boost on it artificially, but now you are talking about it getting hyper complex.
The whole idea behind a turbo charger is that you are enhancing performance of an engine. You are basically taking an engine that has 5 horsepower and you are making it so that it is 8 horsepower. Well, the tradeoff is how much weight are you going to have byadd to get this amount of horsepower.
It is cool to have a turbo bolted on there, defintely cool to have a turbo charged wine. But is the added weight actually giving you any benefit? That is the issue when you start to deal with bolt on horsepower like a turbo charger or a super charger.
But what we are talking about here though is the turbo charger, and how to get it to work. You are going to need a very small turbo charger, the smallest you can get. There are some motor cycles, 4 cylinder motorcycles that have turbo chargers on them. That would be the kind that I would suggest you get.
Now you are going to notice one thing about dealing with these turbo chargers that they weigh about 15-20 lb. just by themselves. If you weigh a standard of 5 horsepower engine, it weighs about 40-50 lb.
The CentrifugalSupercharger Manual is free with the purchase of the plans. In it are details on how to mount, what tricks to use when supercharging engines.These are some related articles on Super Charging and are well worth the read:
So you actually added a lot of weight just for a turbo. So if you are considering using a turbo charger for adding power to save weight out of your package, that is not going to be your prime objective. It is going to be more a show piece. It is going to be a lot of headaches, because of the oil system that you are going to be dealing with.
The turbo charger as we have said before, uses the exhaust to turn the turbine to turn the compressor. There is heat added from the exhaust pipe. The heat is going to get into the intake side. So you need to be aware that. You may get some detrimental performance because of the heat.
