It's true. Mine spits flames and bangs. Also I'm 10 years old.

hey guys
i own a VW Polo 6r 1.4l petrol 2011-2012, i get about 85-90bhp. My goal is to achieve near the 200hp mark, i was thinking about remapping but i dont understand the difference between the stages so if someone can explain to me that would be helpful.
is it worth remapping?

i have looked into supercharging my engine but i am not sure if the supercharger i have chosen is compatible so i will upload some pics and if you guys could advice me.
Is it possible to turbo charge a non turbo engine?
Basically i am happy to hear any suggest to get 200bhp as long as it doesnt cost me a arm and leg so i will be much appreciated if you can give me some rough prices so i get an idea.
I will upload a pic of my car, please dont be fooled its not a gti model it just had the badge and front grill done by the last owner, which doesnt look to bad so no haters.
supercharger ENGINE CODE : CAV CAVE
P/N: 03C145601E
thanks guys

Probably not the answer you want. But I'd say buy a different vehicle. Either one that does what you want from the off or a better modding platform. What you have is undoubtedly a fine car for its intended purpose. But you'd end up spending a fortune to likely end up with a disappointment and maybe a car that is overall worse than where you started.

zayn100 - no offence but why don't you run off back to Facebook. I'm sure there are many people with similar levels of understanding on there, you can spend all day yanking each others chains & give the adults some peace

Was it R11CO who once signed a thread off with "DISMISSED"?

I supercharged my MX5.

I used an Eaton M45 blower off a Mini Cooper S. This is a tried and tested mod so I didn't need to go into the blower efficiency and rpm calculations too much but unless your blower has been fitted to others with the same engine, you'll need to do the maths to make sure it's going to work

In addition to the blower itself, I also needed to do the following to make it work:

• Fabricate mounting brackets and additional pulleys to deal with the belt.
• Fabricate a new crank pulley and power steering pump pulley to take the 6 rib belt (the car used a 4 rib as standard)
• Spend a LOT of time ensuring belt alignment and tension was correct
• The stock ECU couldn't handle the addition of the blower as it uses an air-flow sensor not a manifold pressure sensor, so had to replace the MAF with a *MAP and use an aftermarket ECU.
• Bigger injectors as the stock ones couldn't handle the increased fuelling requirements
• fabricated adapter for the inlet manifold
• fabricated throttle cable mounts and a custom throttle cable as I relocated the throttle body to the other side of the engine
• mounted a trigger wheel to the crank pulley as the stock crank sensor didn't have sufficient signals for the new ECU to read engine position
• fabricated a mount for the new crank angle sensor
• modified the mounts for the radiator so I could move it towards the front more to allow for space for the additional bits plus the intercooler
• fabricated mounts for the intercooler
• Due to moving the rad and fitting the intercooler, a new power-steering pipe cooling circuit needed to be made as it's location was now occupied by the rad
• removed exhaust heat shield and wrapped manifold as there wasn't room for that plus the supercharger
• relocated washer bottle as it's original location was now occupied by intake pipes (which meant buying a specific item to mount behind the scuttle panel)

had some fun rewiring the stock ECU so it was bypassed for engine management but still operated the immobiliser and ABS as well as controlling the dash, apart from the tacho, that was driven from the aftermarket ECU

Then spent around £300-£400 a day for mapping sessions to get the engine map right.

All in all I spent about £6k on the full, completed supercharger install.

2 years later, the engine blew, holing pistons 1 and 3. Turns out that the crank sensor mount got bent somehow, and so the ignition timing was running advanced by a TINY amount. Not enough to notice it day-to-day and no noticeable pinking, but enough that, over 2 years it eventually broke the engine.

Engine mods like this are rarely painless nor cheap

Take from that what you will OP

Is there thread for looking for a supercharger?

Its for a toyota yaris that is being modified currently

Toyota Yaris 1.5 NCP13 Blitz Compressor Kit Manual Transmission brand new is over 3k

That seems pretty inexpensive - I'm guessing you also invested a lot of time and expertise.

I have tried to avoid adding up how much I spent on my RV8 supercharger conversion, but I suspect it was similar - not counting the pretty substantial suspension, brakes and transmission upgrades that were needed before the car was ready for that power level.

I did a lot of it myself but had a hand with some of the machining and fabrication.

In hindsight, tho, some of those bits I chose to get done were down to me thinking they were beyond my skills, but now realise I can do it.

So after having blown up the stock engine, I'm dropping a 1UZ in instead and doing it 100% myself.

They say good decisions come from experience, and experience comes from bad decisions. Remember that most of the cranky old sods who are telling you it's an unrealistic project started off in a similar situation to you.

Rather than jumping straight in to something so ambitious, I suggest you focus your time and energy on keeping the car clean (not just the paint work) and take on simple maintenance jobs such as changing fluids and consumables yourself. Over time this will teach you to figure out how electrical and mechanical systems work and get you familiar with the tools. Also focus on improving your driving. Obviously you're a great driver (we all are) but hopefully you expect to improve further. Work with RoSPA or IAM to improve your road craft and defensive driving - it'll make you safer and easier to get cheap insurance. Being a safe driver is absolutely essential to being a fast one. Also focus on improving your car control skills. Try your hand at an autotest and a sprint. You will probably enjoy the chance to go as fast as you and the car are capable without worrying about the law. There are classes for every type of car and you don't need a rocket ship to win. The skills you'll learn here will carry over for free to every car you ever drive.

And when you're ready to make or buy that much faster car you want, you'll be able to drive it safely and take full advantage of the extra performance.
