Yeah. In USD it is still a lot. Financially it makes no sense. Best buy a GTI and get an APR tune or a used Golf R.

Itís more about the build process and having something different and unique.

And the smoothness and sound of a 2.5T is addicting.

Ya Im looking at getting a new car in a year or so. either a mk7 GTI or a WRX. (if its a GTI i want the one with the new headlights) still lots of time to decide. wouldnt mind keeping my golf for a daily back and forth to work since its about 750Km a week.

Our engine have a huge potential due to the 5 cylinders and his smooth delivery. With an aftermarket intake manifold, the dyno curve become more linear and can reach number near 220bhp.

Now let's say you want to boost it, your car is actually producing 220bhp at 14,7psi which is the atmospheric pressure at sea level. If you boost your car at 10psi, you engine will be running at 24,7psi which is 1.68 times more than 14,7psi, in other words, the car's performance is 1.68 times more than when it was naturally aspirated. 220 • 1,68 give 370bhp.

220bhp @ 14,7psi
370bhp @ 24,7psi (10psi boost)

The drivetrain loss is about 10-15% (37bhp - 55bhp) so theoretically :

~ 315whp to 333whp @ 10psi boost

A GTI boost near 12psi and produce way less than this. Working on a GTI cost less than boosting a 2.5 since the GTI already have the turbo setup, but the 2.5 have way more potential in my opinion and it sounds so good plus it's super reliable and a good platform to work on ! I wouldn't trade my 2.5 for anything else than an other 5cyl such the Audi 2.2L 5cyl turbo

What did you do to your 2.5L Golf today

Havenít posted in awhile - thought Iíd share some news. I have a 2012 MKVI Golf (2.5L), and have done the following mods (AEM short air intake, Integrated Engineering Stage 1 tune, and an AWE cat back.

I was finding the cat back to be unpleasant between 2000-3500 rpms and in some cases it would set off car alarms at work.

Talked to the folks at 425 Motorsports and they were able to fit a Vibrant 3Ē ultra quiet resonator in where the suitcase style muffler was on the stock exhaust.

Super thrilled with the results

Verdict:
$100 parts + 2.5 hrs labor
No more cabin resonating while driving
Smooths out the sound of the engine
Minimal performance loss
Approx 10% louder than stock

If you werenít sure about the cat back, this addition makes it all good. Highly recommend.

Great,
you got her sorted.

I've helped about 5 people with their 2.5 exhaust, from what I've seen leaving the centre muffler in place is the best thing, it leaves enough back pressure to still results in getting good torque all round.

Adding a GTI Axleback suitcase gives the GTI dual exhaust look but keeps the noise leave civilized (stock quiet).
Adding a 2.5 inch Y pipe and having a shop fab dual exhaust pipes to fit the GTI valance and exhaust hangers, result in same performance as the GTI axle back suitcase but with a bit louder 5 cylinder sounds but without any drone.

Thumbs up ... now for what I did.

My drivers side wheel bearing has been giving signs of failing soon. While driving on a straight section of road, if i turn the steering wheel slightly off center to the right, I can hear a slight howl which goes away when I turn the steering wheel back to the left.

Yesterday knowing that I would be leaving for South Carolina today, I replace the left wheel bearing, if I'd known I would have done the R&R when I replaced the CV boot last August. Once you've done a CV boot on one of these Golfs the wheel bearing is just as easy but not as messy as doing a CV boot. Before removing the Wheel Bearing I could hear noise when rotating the bearing and could feel a bit of roughness. Once I started wacking the bearing with a 4 lbs hammer to get it off the steering knuckle, the bearing started coming apart

New wheel Bearing is super cool and no howl off-center glad I replaced it, now I go full attack mode into corners once again.

EDIT: If I had let the bearing get worst the howl would have gotten worst, usually people think it's their tires that are bad not thinking that the bearings can cause the noise. If it got worst, the bearing would get loose making the tires wear badly and making a good alignment almost impossible.
