@IsentropeMachzahl 2 месяца назад

@@AdmissionGaming Cam timing (or valve timing) affects how well the engine can "breathe" - how well the exhaust gases are exchanged with fresh gas mixture. This is known as volumetric efficiency (VE). The more air you get into the cylinder, the more fuel you can add (if targeting the same AFR or lambda). That means there is more energy in the charge in the cylinder. At the same timing (degrees before top dead center when spark occurs), this leads to higher pressure inside the cylinder. The higher the pressure, the greater the force on the piston and the higher the torque on the crank. Power is just torque times RPM and a constant. Hence, improved valve timing increases power.

4wd -rwd. Not trying to be cheeky, this is what I do and iv got a switch too. Iv got a 260rs and the factory way to make it rwd for towing is by removing the wire (green clip on mine) when the car is off, behind the drivers kick panel. Start it up and you should see the 4wd dash light flick on then pump the brake 5-6 times then the light should hold steady and you can hear it depressurizing. Put a switch so you can do it easier, but the car needs to switched off when ever doing it on or off.

@jesseyoung4295 2 месяца назад

With a n/a engine the biggest limiting factor is air intake. A tumed intake can get a little above atmospheric pressure, but otherwise your engine is only capable of pumping roughly 2 liters of air in, which can only burn so much fuel. You'd be lucky to make more than 200 hp.

@itsdundee3320 2 месяца назад

I don't get it, even if the engine is more efficient, why would the boost pressure drop? the only thing affecting the poost pressure is the wastegate and the tune, but if you didn't touch the tune, wouldn't the boost pressure be the same? The wastegate opens on a certain pressure, which it didn't get, so why is the boost lower?

@MotiveVideo 2 месяца назад

Thats not how turbos work. Making engine either larger capacity or more efficient via cams, intercooler etc, the car will consume more air for a given volume of flow. Boost is simply a by product of how much air turbo pumps out vs how much air engine consumes.

@itsdundee3320 2 месяца назад

@@MotiveVideo Thanks for the reply! I get that, but if the turbo is capable, shouldn't it still build pressure until it reaches the wastegate opening threshold? Since even if the wastegate is electronically controlled, it would not open and it would build pressure to the desired amount right? Or am I missing something?

@pinsandscrews6459 2 месяца назад

@@itsdundee3320 Think of it this way, Boost Pressure is the measure of how much air is still being pushed into the intake that can't make it past the valves when they are open. If the boost drops off after a change, but it makes more or the same power, it means the engine is able to take in more air than it was before, hence lowering the pressure still in the intake.

@itsdundee3320 2 месяца назад

@@pinsandscrews6459 That makes sense and I understand it, but they could get the turbo pressure back simply by adjusting the tune. So the turbo wasn't small for the new system. So it can't be the case that the turbo could not push enough air to reach the same pressure. Sorry 😅 What do I don't understand? Wasn't it the case of too much cam overlap? Since in my understanding the turbo will keep pushing until the wastegate opens, which can't open until it reaches the same pressure as before. so unless the turbo is too small, u should not see pressure drop. Which wasn't the case. Hence why pressure drop if the turbo can supply enough. Sorry.
