How to actually make your car faster

[JollyJamma]

and void becoming a RICEr.

Seriously. This guy knows his stuff and has some good points. Just putting a freeflow exhaust on your Vtec and making it sound like a fart cannon, doesn't make your car actually faster. It just makes you fall into the 18-24 year old douche RICEr category.

lol, its a complicated balance. Would love to watch this video but alas, no sound at work. However, even putting a big exhaust on, the flow from low rev affects the output, and having a large diameter helps at high revs...the best balance, put big exhaust on and put exhaust valve in place. Also, those cone filters, utter waste of time. Do you think the manufacturer would not have installed them if they were better?

My gripe - I think noisy cars and bikes are a waste of time. My idea of performance is you barely hear it and its gone. I do understand that there is a point where noise needs to be there to have the kind of performance and I have respect for that, but I don't want to hear your Suzuki Katana revving at 15000rpm with a slash cut 5cm pipe on thinking you are the chief.

The call of the greater spotted tappit... often seen in parking lots revving the heck out of their bikes... or in the pit lane sounding fast, when in reality they are like a snail out on the track... all show and no go.

Craziest performance mod I ever made to any car: Remove all weight possible from my 1600 Beetle. Removed all seats except driver's, spare wheel, replaced the battery with a tiny one, fibreglass boot & bonnet lids and alloy wheels. Unfortunately I never put it on a weigh-bridge but I easily removed 50+kg from a 800kg car. The difference was very noticeable.
I had fat wheels at the back and skinnier ones up front for "normal" driving around, but sometimes I'd switch them around for some drifting madness. I miss that car...

Weight reduction is number one mod, usually the cheapest as well.

Just like how some people like to feel their ear drums bleed with the amount of bass they have in their cars, some people just like noisy cars.
Ignore them and let them be?

Except with bikes its a dual purpose on noise theres an old saying amongst those of us that ride " loud pipes save lives" when you are coming in hot you want people to know you are there.

its always been weird for me people who are like my golf jumbo is faster than your M3 ..... yeah but its a golf jumbo?

In the not not too distant future ricers will be a thing of the past, we are all going to be talking about the max discharge rate of our car batteries, the max continuous discharge rates we achieved while putting our EV cars on the dyno, comparing battery energy densities, pro's and con's of different battery chemistry's and its going to be glorious, embrace the change!

I would if they didn't actually think that they are legit street racers with fast cars. Usually, they're just kids with no money and a Honda Civic.
My neighbours kid and his mates and the fucking cliche of kids with an attitude and a shit car they take very seriously.

Being woken up at 3am to a revving 1.4 Citi Golf with a shit exhaust, isn't my idea of fun.

Also, things that don't make your car faster:
Higher octane fuel - the car was designed to work with it in the first place. By putting in lower octane fuel, you just lose your engines ability to accurately time the cycles and thus, you lose power.
Fuel boosters - they cost ~R100 and actually reduce power.
Chipping your car - it just causes the car to run too lean or too rich and can destroy the engine
Installing higher capacity fuel injectors without doing proper mapping of the ECU - excess petrol is just pushed out the back and onto the road.

What does work:
A better intake manifold with a better fuel injection system and tuning. EngineMasters took a 350 Chev small block from a stock 220bhp to 650 with just those to parts and a days tuning.

If they wake me up I'm sure to be pissed off, Luckily the dips that used to do it next door stopped shortly after another neighbor that has a proper racing car that makes the ground shake, took it to their front gate and made the earth rumble during the mothers nap time. Her kid's revving crap stopped.

I agree, doing that crap at night is not on. But I don't mind a "Ricer" pulling their car out and going on their merry way, or even attempting to braaap at a robot.
I know what their car can do and I couldn't really care, in those situations it doesn't really bother me.

I can't really say much about what exactly to do with increasing engine performance but I know bolt on exhausts and fuel additives do jack, Either put better internals into the engine and slap a turbo on it and tune it. xD

Adding to this. Pod fliters

Might Car Mods did a pod filter test and all of the pods tested failed to do anything. It's the first thing people do on their car when seeking BHP.

Oddly enough, my car came in supercharged form which is great but I can't do it without the forged pistons. From Wiki:

4A-GZE
The 4A-GZE (produced in various forms from August 1986 through 1995) was a supercharged version of the 4A-GE. Based on the same block and cylinder head, the 4A-GZE engine was equipped with a Roots type superchargerproducing 8 psi (0.6 bar) peak manifold pressure, and the compression ratio was lowered to 8:1 with the use of forged and dished pistons. Although fitted with upgraded pistons, they still had the same ports, valve timing, and head gasket as the naturally aspirated 4A-GE engine, although T-VIS was omitted. It was used in the supercharged MR2, rated at 145 PS (107 kW; 143 bhp) at 6400 rpm and 190 N⋅m (140 ft⋅lbf) at 4400. In 1990 it was updated with the "smallport" cylinder head, 8.9:1 compression, and MAP D-Jetronic load sensing and a smaller supercharger pulley producing 10 psi (0.7 bar). These updated 4A-GZE engines were rated at 165 PS (121 kW) and 210 N⋅m (155 ft⋅lbf) for the 1990/1991 AE92 Corolla and 173 PS (127 kW) for the AE101.
The 4A-GZE is also popular for turbo conversions, as many parts do not need to be modified to support the extra boost

Yea I watch MCM religiously.
Thing is they were just putting on pods without changing mapping? You have to account for the difference in temps and airflow.

Yes but then you need to change the fuel injectors too and do a complete remap of the whole system.

I think the basic understanding is that cold air = more power due to the increase in cold air density but it still doesn't work.
Your ECU needs to be remapped but it can't take advantage of the minimal increase in air density because it's designed to work with huge changes in air/fuel rations with turbos and superchargers. Your air/fuel ratio needs to be accurately monitored and controlled, otherwise your engine will die.

If you add a turbo putting in 1.5 bar pressure, you need to put in 1.5 times more petrol to keep the air/fuel ratio the same. Putting in more air with the same amount of fuel won't work and may result in worse results.

The MCM guys put an STi turbo on their Subaru Forester and it produced the same power afterwards because the ECU injected the same amount of fuel and air into the system as before to keep the engine healthy. They did an ECU tune and the power increased.

Air superchargers are also stupid whilst I'm on a rant.

Thats what I am saying and why I see that test as unfair in a way.
You cant flatout say that pod/cone filters dont work. Sure as a standalone change probably not, as a supporting mod it can make a difference.

While on the subject, one of the most common upgrades on Foresters is STI turbo and intercooler xD

Yeah the AMG's are the funniest thing, you hear them cough, splutter, scream, change 5 gears and they've barely gone 20 meters.

Superchargers are great and all but you cant beat a turbo dump

AMG, Some sound really good but those new-ish 4 pot turbos are really..... Not the same as them big V8 AMG models.
Get alot of those AMG 45s that make loads of noise but don't do much other than that.

Why not both? xD

 

[Bencrisp]

I love the idea of a supercharger, not as great as turbo because of the parasitic effect superchargers have, however...this is the big thing...that supercharger whine all day would annoy me

Because the exhaust will spit out your pistons when you try beat the Katana with the cut off exhaust

lol, you don't need much to beat a katana nowadays xD
There are quite a few twincharged engines out there.
