Diverter Valve - Do I need one

[hotcar1600]

Hey guys,

My polo is getting an APR tune this week, as well as engine mount and gerabox oil.

Was wondering all previous experience as to whether I should change the diverter valve at the same time? Do i need it??

Cheers

IMO, yes... it should be done shortly after a retune, same goes for the engine mount (which you're already doing).

I've found not only have I gained top end in 4th/5th gear (you won't notice the leak so much in the first three gears), my car is also now idling a little smoother and overall responding a little better post-valve.

That said, my findings may be a one off.... its possible that my valve was leaking even worse than most.

The stock one may not stay closed at full boost.

The stock diverter will normally do the job, but chances are it wont last and may be stopping you from holding boost.

Do you need to do it now? No

Should you think about doing this soon? Keep it in mind for future spending.

i ended up getting one through ebay $60 and it works really well

With the exchange rate as it is you can get an APR R1 DV one from the states for a "lot" cheaper then through any local supplier.

Ditto, mine is a copy of the popular Forge item and only a fraction of the cost.

yes I would have to agree also. It is a very worthwhile upgrade after a flash tune. I myself chose the APR R1, although a little more expensive, is totally maintenance free & set and forget unlike a typical piston driven bov, like the forge, which require periodic maitenance to ensue the pistons moves freely.

The performance gains I got with the R1 diverter were quite astonishing compared to the stock Bosch valve. You can expect the boost to come in a lot earlier, even as low as 1300RPMs, and turbo lag is virtually eliminated through gear changes and the boost holds for a lot longer. It was one of the first things I upgraded post flash tune. It was the first of the air intake mods/upgrades I did and to be honest I found the gains far inexcess of what you get from the Forge TIP and Seat intake mods combined. No joke.

Its not critical but I would suggest doing upgrades like this a little at a time, which gives you a sense of what each one has done instead of getting them all done at the same time and really not knowing what upgrade has added what.

Cheers

I tried buying my APR DV1 from the USA but no one would sell one to me because they all pointed to the fact that APR Australia sells them here and they were not permited to sell them to me. Or thats the somewhat convoluted excuse they gave me. True story.

I have a Forge 007P and am very happy with it. I also bought the spring kit, and put the 17 to 22 PSI spring in it too.

North American Motorsports ship to Australia, I got mine with free shipping and it was only A$135 landed as it was on special.
