The tilt of the wheel is known as the camber angle. Tilting the wheel in that manner is called negative camber. Doing it the other way around (top outwards) is positive camber. Mounting the wheel with a negative camber improves grip under hard cornering as it counteracts rolling. On a completely level tire (0 camber), when a horizontal force is applied to ...

In this specific example the car is more than likely using airbags. When you decrease or increase the height of a car it affects the tire alignment by usually causing positive camber, pushing the top of the tires outward, this is a highly modified suspension system. This particular person has modified their suspension so the top of the tires tuck in when ...

The rotary engine is still a pump so opening it up helps it rev higher and make more power. Opening the inlet and exhaust ports is a big way to make more power at the engine. You still need the rest of the path to open up as well so opening the exhaust and intake path helps. Earlier Mazda RX-7s had anti pollution gear that killed power. There was a reburn ...

If the question emphasis is on cheap, weight reduction is your friend For many reasons: A lighter car accelerates more quickly Because physics. Since you're planning to drag race, top speed should be less of a concern here. It costs nothing except time and effort Plus it'll help you get familiar with how the car is bolted together There's a chance you ...

Yes, it is possible Albeit with some trade-offs. A modern-day road car is an amalgamation of several sub-systems, and electronics usually have an important role to play in them. The nice thing is that many of these sub-systems were present long before modern-day electronics became commonplace: Engine The heart of the beast remains mechanical to this day, ...

For most vehicles, the cheap but effective upgrades are: Advance your timing: 2 degrees of timing advance can give you a bit more umph, you may need to start using intermediate fuel instead of regular though Exhaust header: on most vehicles, this is the best bang for your budget buck. Replace your stock exhaust manifold by an exhaust header, let the engine ...

There is a product "rivnut" that you can put in the hole, do up, and it locks itself into place... Like a rivet, but it has a thread and is thicker / larger. Then you can just "bolt through" - make sure that the bolt does not push on the outer skin when it is done up though ! There are many versions, this type may be interesting for you: Found here : ...

There are a number of ways to go solid-state ignition and there are a few open source projects that allow you to build your own ECU and loom and utilize an ignition system from something else. One system that instantly springs to mind is MegaSquirt which is a programmable ECU project that uses Ford EDIS parts. Depending on the engine configuration you have ...

The question assumes that the car is a drivable configuration, which may not be true. This car and similar photos you have seen probably have Height adjustable suspension this allows the ride height of the car to be changed on demand. In all likelihood the frame of the car pictured is sitting on the ground. The suspension has been lowered (or tires raised) ...

No. This modification is intended for Gen I/II Small-Block Chevy engines only. What I failed to realize was that while the cylinder numbering convention stays the same across Gen I/II SBC's, the firing order is quite different: 1-8-4-3-6-5-7-2 With this firing order, there is no concern about bank imbalance when performing the 4/7 swap: 1-8-4-3-6-5-7-2 | ...

The D16A8 engine is the equivalent to the ZC DOHC engine (non-vtec). The VTEC head from the D16Y8 will not bolt on. Neither will the head from a B16A1. The head on the D16A8 is superior to that of the D16Y8 even without the VTEC. It flows better and really likes to be turbocharged. I suggest you turbocharge the engine instead of an engine swap. Cheaper and ...

One of the most popular modifications on pre-injection cars is conversion to multiple twin choke carburetors. For example Weber DCOE carbs. Typically this involves changing the inlet manifold which will be specific to the engine on one side and generic Weber / DelOrto fitting on the other. Another popular mod was adding a high lift camshaft, "port ...

You can add anything including turbos , intercoolers, fuel injection, nox injection - just takes money and technical knowledge. If you want a relevant example of design progression look at the inline 6 cylinder Jaguar engine that dates back to the late 1930's or 40's - original power about80 bhp and when they finished using it 10 or so years ago it was at ...

the higher end trims, which all come with keyless ignition So, I'm going to actually go against the crowd here and say, yes, this is completely manageable. Think about it- If they sell the same year model of Tacoma with a keyed ignition module, buy that. It should be designed to enable/disable roughly the same features as the "base model" that comes keyed. ...

A few assumptions first: It is an open loop alpha-n type of injection system (just has a TPS, no MAF or MAP sensors, no O2 sensor, no catalyst) If the above is true, you could probably make it run using that method, but there will be a trade-off, the difference in fuel requirements at one condition (say idle) between the 250 and 350, will be different to ...

TL;DR It's not possible to prepare a Virago 535 so that both short and tall riders can ride it comfortably. Full answer After investigating a lot into this issue, and even after trying a few other motorcycles, I concluded that it's not possible to prepare the small Virago so that both me and my wife can ride it comfortably. The size and ergonomics of the ...

It is entirely for style. This is called "camber". The tires will wear in an odd manner. The tire contact with the road is usually a rectangle on the bottom of the tire. This extreme camber makes the contact patch very small and near the inside edge of the tire. This does significantly reduce grip.

I have only ever had one normally aspirated Subaru, and didn't mod it much, but from the mods I have had on various turbocharged Subarus over the years on some Imprezas, WRXs and my sorely missed Litchfield Forester STi, I wouldn't suggest bothering with this. My preferred route with mods (backed up by Subaru specialists and modders) is: brakes/suspension/...

As @Compro01 said, a few degrees of camber helps cornering. Too much camber places all of the weight on a small section of the tire, making it wear out faster and reducing grip when you're driving in a straight line. Racecars can get away with that because the tires only need to last for one race. The photo in the question is definitely a case of too much ...

There is such a beast known as an analog computer. The computer uses OpAmps to implement complex formulas in an entirely analog fashion. The formulas implemented take input from things like mas air flow, air temperature, coolant temperature, engine rpm and provide output to the fuel injectors. With enough time most if not all systems in a car could be ...

Brain dump, no real experience With keyless ignition, you have a key fob, some sensors that detect the key fob, and some sort of ECU that interprets the input from the sensors. If this whole setup is separate of the ECU/BCM, it might be easy to rip out and replace with the ignition switch. If it is integrated, you will need to find some way to trick the ...

As long as the batteries are fully charged and in good shape, by placing two 950 CA batteries in parallel, you will get 1900 CA ... you are exactly right. Just understand what you're doing when you put them in parallel and you'll have no issues. If you put the two batteries in series, you'll still only have 950 CA, but you'll be pushing 24VDC worth of juice, ...

For a vehicle to live in you would be much better off with a van. Even a fairly large estate car will have much less internal space for an equivalent floor area. Another key consideration is that cars are not generally very well insulated as they have large areas of glass for the sake of visibility and will usually be to hot or too cold and create terrible ...

I'd suggest a good starting point for you to look at is the tuning options available within the Gran Turismo games (4, 5 or 6, haven't played the earlier games so I don't know how the tuning options vary in those games). Lots of the time they don't allow you to do modifications you couldn't do in real life (due to restrictions of the type of engine etc.) but ...

Cooling air into the engine is always going to be a good idea, as heat soak reduces the power of an engine. A turbo does heat air, simply by compressing it, but you will still get a direct benefit from any cooling you can do, either before or after the turbo. This is why any major performance improvements with a turbo tend to end up involving an intercooler....

The main problem that I would expect is that you'd probably get disagreements with the computers readings, which would start messing with the EFI mapping. First problem is - does the TPS you're looking at actually use resistance on the signal to measure or does it not (although I believe the VAST majority of TPS modules do work that way). After that, is the ...

You can have a significant impact of the power output of your engine, but you won't achieve a huge amount and, after a certain amount 10 or 15% for example any gains will become hugely expansive. Simpler things start with changing the plug, altering the timing, altering the valve timing, porting the intake and exhaust and increasing the compression ratio. ...

Putting the filter into a different position shouldn't cause you any issues. Having it upside down (hole side down), may create the situation you are trying to avoid, though. I take it your overall goal is to ensure the oil filter remains full of oil even when the engine is off, so upon startup the engine doesn't have to "refill" the filter. One of the ...

There were a number of attempts at this in the past with a variety of strategies. As mentioned above, some required custom formats/configurations. The link below discusses some of the issues and solutions (?) the US manufacturers encountered. European manufacturers also had a parallel experimentation track. I know at least one used a large platter mounted ...

In cold climates in is a "standard" modification to have a remote engine starter, so you can warm up the car before using it. That could obviously also be used to run the aircon in hot weather. If someone has two sets of keys, they could lock the doors with the other key still in the ignition. But in the UK it is illegal to leave any vehicle "unattended" ...
