>70,000km polo gti, ability to handle tune?

**arcenite** · 09-09-2012, 10:55 PM

Hey guys!

I just got my Polo GTI today! Can't wait to mod it, but I'm unsure whether should I tune first or should I replace the other parts first such as suspensions/cold air intake etc. As far as budget goes, I doubt I'll be able to purchase everything at one go. I've scoured the forums for a bit and I noticed that some said to tune first, and others, later.

I would probably have enough to get a tune, cold air intake & filter, DV and probably a short shifter. What sort of mod would make the sound of the turbo more distinct? A new exhaust?

Sorry if it sounds really stupid but this is my first time at modding a car, any advice would be appreciated!

Cheers

No worries tuning your Polo.

I always advise getting all the hardware first and then tune for best effect.

You get more of a whistle off the turbo once the ECU has been flashed.

There was just a big Polo dyno day in QLD, lots of information for you in there.

Cool! I was just worried that the stock parts on the car wouldn't be able to take the added power from the tune since it's pretty old. :s

Some elements might not perform 100%, you may not hold peak boost as the stock diverter valve is known to fail, but it may be fine. Worth considering an upgrade to this, ensuring your spark plugs are reasonably new (last 40,000 kms) and you can always benefit from checking your boost pipe clamps are tight.

70k is brand new! I've just had my car tuned today at 123K - these engines are bulletproof and as long you maintain the car properly it is unlikely you'll have any problems. hahaha 70k, man that's only just wearing in!

Good to know! I'll definitely get those boost pipe clamps/spark plugs checked when I send it in for service. From experience do you guys just buy the parts and fit them yourselves? Would it be possible to get someone to do it without getting peeved off because I imported the parts?

Any recommendations would be appreciated

.

I was reading up on DV's and I understand they're pretty much like BOV's, from my research, it appears that the APR DV's do not produce much sound. Does anyone know of any that are able to produce slightly more sound without going overboard? I might just get the APR ones at the end of the day though if it's too much of a hassle because I don't have a garage nor the experience to DIY

Diverter valves do just that, they divert the excessive boost from when you close the throttle back into the intake stream instead of into atmosphere like a blow-off valve. The only benefit of a blow off valve over a diverter valve? The ricer noise effect

Diverter valves also vent back into the intake stream due to emissions regulations because your intake has the breathers for the crank case etc, these gases are not allowed to vent back into the atmosphere. Diverter valves can also negligibly increase performance over blow-off valves due to pre-charged air already in the intake so the turbo theoretically doesn't need to work quite as hard to generate boost, a blow-off valve removes all boost.

An APR diverter with a tune is plenty loud. Load the engine up and change gear and it sounds like I've got a full vent to atmosphere sometimes. I do it to stir the ricers

If you want it any louder fit an open air pod filter.

I'll have an APR R1 diverter for sale soon..

Wouldn't that make a BOV a real world performance reduction over the DV since throttle response would be worse on the upshift?

Got my Polo done with an APR Stage 1 + tune at around 80,000 KM

Its now getting to 165,000km with no problems at all (touch wood

)

So no problems at 70,000 odd Km. As NP said these engines are bullet proof
