Wish I could say I’ve adhered to No. 4 better, but as a poor college student, I’m lucky to even be able to put fuel in at all.
You can burn your cat.
It’s actually not true, just has to be size correctly. I spoke with the team engineer from Subaru’s Rally America, and he said their STI makes no more/less power with or without the cat on. You just need to ensure the cross sectional area and flow meet your power requirements. Sizing is important. Cats are great. Leave ‘em on or buy one that’s the right size.
for turboed car yeah, actually for n/a engine, too less back pressure will decrease the HP
Thing that stands out most in this video is when he is talking about the oil not flowing through the turbo as quick??? Turbos run off air, primarily exhaust emissions, hence why turbo charged car s have an exhaust gas recirculation valve. If im wrong im sure someone will correct me. Also when he says about flooring it at low revs will wrech the turbo? Turbos dont spool up until they reach a certain rev limit anyway..
yes the turbo charger compresses air, but they are typically lubricated with oil and cooled with engine coolant. there are seals inside the turbo to make sure these fluids dont get in the intake. if you have ever seen one connected on a car you will see the hoses that run to the center of the turbo, these are typically oil supply/return or coolant lines.
Your turbo will need some kind of lubrication, and the quicker the oil flow is better because turbo runs quite hot.(Oil flow quicker so they don’t break down because of heat in the turbo.) Flooring at low rev is NOT doing anything to the turbo but the engine will have to work harder to give you that torque you request.
But gas prices are already ridiculous where I live, especially the premium-grade ones. If I get a turbo/supercharged car I’d rather install a new ecu with a flex fuel sensor, ethanol is way cheaper than common pump gas here, and they even mix some of it with gas, somewhere around 25% ethanol and 75% gas.
Yeah “uncontrolled matter” ;)
I agree with a lot of the comment in the video… but manufacturers build in tollerances for incompetent drivers who don’t look after their cars. So in basic terms if you car or engine goes “bang” you know you’ve driven it too hard or not maintained it well.
So…some cars have auxiliary water pumps that run when the car is turned off so that the turbo can cool down.
Indeed, some
NA cars also has this… the VR6 has this AUX water pump as well.
I disagree with 4. and 5 4.: Why should i go up from 95 RON to a 102 RON Fuel wich cost up to 20 Cent more per Liter in Germany when you got 0 knock on the 95 RON fuel? In Germany Fuel has to undergo a quality check before it can get sold so the Fuel has always the same RON Value. Its very very unlikly if not impossible to Fuel 95 RON and get Knock because the quality of the Fuel is Bad. For an Example i have checked my Cupra with 98 RON (Manufacturer recomanded) and 102 RON Fuel and there is no knock at all at 98 RON so there is no reason to pay the 10 Cent per Litle more because it has 0 effects. And Point 5 is only for Drivers wich are new to Turbo Lag or Cars with giant Turbos. Most modern Turbo Cars can be driven quite hard on exits because the Lag is very predictable, also there is a lot of diff magic happening. Only Idiots wich only know the Binary throttle Operation aka (On and OFF) or Cars with Extremly Big Turbos will have this problem.
For stock cars it’s not that big problem, but if you have custom-built car which is made barely-not-to-knock, then there’s way less chance to get into troubles if you put 100-octane fuel, than regular 95 - for example when he was talking about pre-ignition. But i guess new stock cars must be able to handle flooring it at whatever revs.
