Dyno results after Full Non-Res Milltek, Forge FMIC and Forge diverter valve fitted!!

[robihe]

dont know if this is what should be expected or im experiencing leaks in boost or other mechanical problems. But after the results of the dyno with the Milltek exhaust, forge kit and forge valve installed, the pog only produced a shocking 97.1kw/atw. I was expecting more significant gains from what it produced stock with 90.8kw/atw with the aftermarket mods. Anyone have the following mods and produced similar or bigger gains?????

theres still the last phase of the tune to come and im hoping it pulls alot better than what its making now.

i think if you decide to get a flash done you will get significant gain compared to stock tune. i got an extra 11 kw from the fmic but that could be due to different dynos

btw whats the non reso like to live with on a daily basis? excessive drone or still ok

[instigator]

you wil have more gains when you remap the car.

if you just remap a polo without mods you will have about 190 - 210Hp.
when you put a milltek, DV and FMIC on a polo and than get it remapped you will have somewhere between 215 - 230Hp.
thats when those upgrades are really going to show what they are worth.
so 11Kw on a stock polo is not bad at all

The Forge FMIC restricts the boost a little, but keeps the intake temps down.
You should look at a pod filter or Seat intake to help the breathing.

Your figures are not surprising, but if you get a good tune to match your mods, you will be set... Its all in the mapping, as the stock boost is around 10 psi, I'm not surprised you didn't get big gains.

That's about ~130kw at the flywheel, that's pretty consistant with a few numbers I've seen and heard. Look in one of the dyno day results threads (sydney's had more polo GTI's) and compare your result with the posted ones

@bfeboi: the non-res looks great and sounds great, but not worth the money u pay.
@instigator: sorry i forgot to mention ive replaced the stock filter with a pod.

it just took me by suprise as u have all these other jap cars that gain an extra 15-20kw/atw from just an exhaust, yet these cars couldnt
even gain 10 combined with a front mount and the other intake mods.

Jarred, the dyno's from Syd were all ATW figures.

Robihe, the FMIC in our case does not add power, it maintains the power by keeping the intake temps down.

How have you got the pod mounted? If you are sucking in hot air you won't be making as much power. If you have it sitting in the standard airbox, you still have the stock intake restriction.

The standard Polo exhaust is pretty good for standard turbo applications, there is a little restriction in the dump pipe and a bigger diameter through will help.

thanks for the explanation. i should have done my research before committing to spend a heap on these mods. just went with the crowd and what was best for my car. should be interesting to see how well the car goes after the remap. cheers for the heads up everyone!

hey mate how's it going?

german cars are a different animal. whilst exhaust and pod on a jap car might increase things by 30kw or whatever, i've seen boys on the jap import forums swear quite aggressively in their posts with their refusal to believe that a remap can yield +45kw in the polo gti.

different animals.

[instigator]

don't compare a Honda or other japanese cars with a polo GTi or so...
the car's you are talking about are probably N/A, they change the exhaust manifold, wich is important on N/A engines.
i have seen gains from 25Hp from only exhaust, this you will never get from a turboengine that is not remapped.
a milltek or so on a polo is from the downpipe and afterwards.
normally the manifold is not changed. so it's not compareable.
remap a N/A engine and you will mostly (with luck) get 10 - 15Hp.
polo is Turbo so the pressure will be raised, thats why a turboengine can get gains up to 30Hp or alot more
so, comparing a normal aspirated engine with a Turbo one is like comparing you blowing true a pipe, and me doing the same thing with an air compressor :-p

@Noone: we do need better airflow as the stock restricted airfilters so a open airfilter will be good enough for a polo.
mind you that a turboengines don't need the cold air. it has it's own atmosphere.
we have intercoolers to cool down the air so providing a cold air intake will not give much gain, if there will be any...
also totally different with N/A engines which need the cold air from the airfilter as they don't have intercoolers (duh! :p)

I can't imagine why you'd spend all that money on those mods, instead of doing the remap first *shrugs* It's a backwards way of modding a Polo to me.

Robihe, the FMIC in our case does not add power, it maintains the power by keeping the intake temps down.

Yes, and no. It does actually slightly sap power due to pressure loss, it also will add lag. It's a matter of if the temperature reduction can allieviate the negative effects, and for the quality intercoolers I'd imagine they would be close to neutral benefit to power. But yes consistency of power, particularly on a hot day, is the big draw card for most people.

Put your stock intercooler back on - if you have lost ~ 4 psi of boost (as many other have) then on a stock car (no upped boost with software) then you are lucky to get those gains!

[RoSonic]

Here's my before/after forge fmic dyno:



The ecu map was stock at that time. And only other mod was "pd160 intake".

[Water Boy]

Ohhhh.

Yes think its time for a GIAC, CC, APR or Revo tune mate.

Sounds to me that you are the one with the backwards modding idea mate

first hardware, after that, software,
specially when you are going to get a custom remap.

ps: IC is allways better on a turbocharged engine.
you might get a bit turbolag on a stock engine if the IC is a bit to large, otherwise you will not notice it at all.
but it's still worth putting it even if you have a bit more lag.
heatsoak will be elliminated, and thats a factor where Polo GTI's have real problems with.
still it's everyone on it's own, it's a personal choise..
