Polo GTI 2.0l tuning

[deadcruiser]

Just wondering what you did with the hose leading into the stock airbox? Does the aftermarket intake have a place for it, or did you just plug the hose? Apologies if my explanation makes no sense, I’ll take a photo of the hose I’m talking about if that helps haha

Well i can tell you it is a very nicely made airbox with good quality silicone pipes, and the airbox fits perfectly. The turbo muffler delete is also nicely made and fitted perfectly too.

You can choose to run the airbox with or without the lid if you want some extra noise, but without the lid it will let suck some hot air in.

There is definitely some nice induction and turbo noise with the new setup. I have a few pics i will upload shortly.

Can I ask where you bought the CAI kit from. I am about to take delivery of my 2019 polo GTI. Love the sound of CAI's.
There seems to be a real lack of places to buy go bits for the Polo, "ECS Tuning" dont even have a listing for the Polo.

These parts were purchased direct from MST in USA. (sorry for the late reply - haven't been on here much lately).

Good Day Gents

Are there any updates on the Polo GTI owners? I am looking at replacing my ST200 with a Polo GTI but not sure about the tune-ability of the motor as yet, so far it seems that the polo has a smaller turbo compared to the Golf and also higher compression, has anyone done software on the Polo as yet? or even a stock dyno run to see what the torque and KW graphs look like?

Also, does the R600 intake not fit on the polo? after all it is the same MQB platform and the same EA888 motor just a GEN3 and not a GEN2.

looking forward to your response.

Sent an email to George over the weekend and Burger now have a JB4 available for the Polo Mk6 GTi. On the default Map 1 with 3 psi boost more than standard it adds 30 whp and 45 ft lbs on Pump 95.

Group 8: JB4 Gen3B Beta – Burger Motorsports, Inc.

There is bit more to be gained on Pump 98, but as other have found with this model the small intercooler is an issue. As a result an intercooler upgrade is a must for much more power.

thanks for the reply I appreciate it, I also heard the cooler is small, wonder how it compares to the 1.8gti cooler, I suppose the best option would be to get the IS20 or IS38 turbo and bolt it on, it should supply more air at lower spool and cause less heat than a maxed out IS18... if you are willing to change the turbo. Cooler upgrade sounds like a good idea either way.

[Waldip]

I see now on the JB4 site it states that the PGTI does have a IS20, I thought it used an IS18. very interesting

[Sydneykid]

It depends on how much power you want to make, how much higher rpm you can live with (before it makes power) and how much "lag" you will tolerate. Personally I like the instant throttle response of the standard turbo, so adding 50 bhp and 80 ft lbs of torque (on Pump 98 ) without sacrificing anything else is attractive. A slightly larger intercooler doesn't add much noticeable "lag" but even a slightly larger turbo sure does, for my tastes anyway.

Yeah I absolutely agree, there is always that sacrifice. What I dont yet understand is why the power is so much down compared to the Golf GTI? Not so much the KW but the Torque. If it's the same motor with the same turbo why is the torque down so much? I understand that the heatsoak seems to be an issue but the Golf the same turbo makes Way more torque when tuned. What does the PGTI boost stock?
But I must say even though the power is not there that the Golf makes, I am still impressed and happy with the results that the JB4 produces at this stage.

VW have limited the power and torque on purpose with the ECU software to separate the Polo GTI from the Golf GTI to help justify the additional cost of the Golf.

Just like a few years ago with the Tiguan 2.0TSI, the 125TSI, 132TSI and 155TSI all had the same engine and turbo, but power and torque was reduced in the cheaper models to help differentiate them along with equipment levels etc. But with aftermarket tuning, the 125TSI could have the same power as the 155TSI.
