Hey guys ,
So i`ve added a carbonio intake to my car , so naturally i was thinking of going up to stage 2.
So i`d have to add a downpipe , but after looking around a little bit i saw that there is almost no data about downpipes for the new MQB platform , and the data i did find say the downpipe has almost no effect (no added HP) , the once that claim that there is had no dyno graphs to prove it.
What do you guys thing ? has any one upgraded their down pipe and saw improvement ?
Please share you thoughts and expirance.

P.s i Drive a 2014 Leon FR 1.8T.
Thanks.

well you cannot go stage 2 without a dp, so surely it doesn't matter about how much a dp gives you without a remap...?

Regardless, here is mine, before and after bcs dp:



And here is milltek's:



Obviously the car is different but its the same engine block so you get the idea.

ofc you cannot go stage 2 without remap , i curently have stage 1 ECU from Etuners custom build.
And i will upgrade it to stage 2 if a downpipe will be added.
The question here is if there is an actual feel-able difference with and without the downpipe.

The chart you gaved is the difference between stage 1 and stage 2 ?
cuz that seems kinda low , with stage 1 iam getting 250 WHP.

You will feel the difference of a DP without software, if you add software it will be even better.

The graphs above are before and after fitting a DP.

as Andrew says this is just showing the difference between a downpipe and no downpipe, before they are remapped in anyway.

Also, this is for a Golf GTI, dont look at the figures too closely.

EDIT*** wait youre saying youre getting 250 WHP from a stage 1 1.8 tsi, thats nigh on 290 bhp? Are you sure...

yes iam sure , i can even upload the dyno img if you would like.
And again you didnt answer my question.
There is a strong rumor that in the new MQB platform downpipe wont add any thing.
And iam speaking about company's that give you the decent numbers in stage 1 , like etuners / apr etc...
Unlike unitronic for example that adds up to around 220 in stage 1 and stage 2 go to 250 which i get from stage 1 right now without downpipe.

Apologies. Is the question, "will a downpipe make a difference" the answer is yes. The original downpipe is tight and restrictive in comparison to the aftermarket ones.

I have not heard the rumour that a downpipe wont add anything, where have you seen this?

The reason I doubt your 290bhp is that:

- APR give 256 for stage 2 http://www.goapr.com/products/ecu_upgrade_18tsi_gen3_mqb.html
- Revo give 238 for stage 1 http://www.revotechnik.com/product-details/software/seat/leon-mk3/197/stage-1/

So your 1.8Tsi which has 180PS standard, now has 250WHP from a stage 1 map? :rofl::rofl:



i didnt say 290 BHP , i siad 250 , and you can check this on the Etuners site , my car was the first beta test they did , i cant share the link cuz i have less then 15 posts , but go to thier site and check stage 1 leon 1.8T MQB 98 Ron.

All tests preformed on Dynapack dyno , Maxtuning Israel.

I can upload more dyno chars if its not enough , i also tried APR it gave 220 on stage 1.

he must mean 250bhp not whp then, thats more like it

No, he REALLY means 250 whp.

He meant this (245 whp in that graph):

http://www.vwgticlub.co.za/forum/viewtopic.php?t=30113


I guess this engine isn't getting to much attention but has loooots of potential. This is very impressive and I understand the reason to doubt. But then again, there was a time where nobody could believe a simple 1.8t 20vt could make 235 bhp wiht a remap, just because big names where getting 215 bhp. BUT time proved us wrong.

I think the same is happening, this engine is fairly new, and all the attention is over GTI's and S3's and fewer are involved with this engines.

Greeks are known for exploiting little engines, because due to taxes, little engines are more affordable to get. So, they develope EVERYTHING for them and push the bounderies. So yeah, I beleive those numbers.

Here in Mexico, I've seen (from another greek/german brand) 260+ bhp with stage 1 and apr intake... While APR is getting 250 bhp. My point, as I said before, not because big names aren't getting those numbers, doesn't mean they are not achievable.

Cheers.

ANd post related..

I have a A3 8V and installed a 3'' decat downpipe + resonator + muffler delete.

I really felt a difference. With a stage 2 you WILL definetely feel a diference bro, not just in numbers, but driveability, and sustain the torque higher in rpms

Also Remember this is not a k03 turbo.. This is a IHI turbo, better designed and the engine is better also.

I remember a friend of mine installed on his MK2 leon 1.8 tsi a GTI IHI TURBO and got 301 bhp...

There you go, another testimony... :clap:

What remap are you using?

Look before I begin here I just need you both to understand that you can get any number you like with a dyno, im sure I can find one that says I have 400bhp if I really wanted to so we cannot take such statements as evidence.

No, he REALLY means 250 whp.

You lost me at Greeks and taxes...

A resonator is a muffler, so what did you do that for?

I think we are all in agreement that downpipe and stage 2 will drive much better than without.

Also Remember this is not a k03 turbo.. This is a IHI turbo, better designed and the engine is better also.

I doubt half the people in the mk3 section even know what a Ko3 is, so i'm pretty confident no one is making that mistake.

Youre talking about a mk6 IHI and a gen 2 1.8 tsi, different sizes and designs entirely so you cant use that in comparison, that said 300 bhp is still optimistic so I refer you to my first sentence.

Danny, sounds like youve spent a lot of time and money in you mk3 and it looks great too, only thing I'd say is get rid of the forge and get a gfb and go buy yourself S3 fmic. I am unfortunately still a little hesitant to accept your 280 figure, but you should logically be close, once you sort that cooling out :)

There you go, another testimony... :clap:

What remap are you using?

I too am curious who the tuner is, and I am not suggesting that APR will have the best map by far, I dont know and I doubt they will, but what I am suggesting is that if they have spent the time to produce a stage 2 map then it shouldnt be so far off the mark from a stage 1 tune by somebody else?

Lets not forget the initial statements in this thread is that a somebodies stage 1 tune is producing 34bhp than the worlds most infamous tuner's stage 2, thats the pill no one can swallow!

And as you say, all the attention is on the GTIs and Cupra's of this world, so then surely there should be a difference between GTI's and 1.8tsi's stage 1 figures, or do you think its logical for both produce 290bhp given the hardware differences?

And dont think that im bashing the 1.8, im always a supporter of the underdog, and with the polo coming out with the 1.8 again it can only generate more interest and tuning products for you, so exciting times! The day I am forced back to a derv, i'll be going to get one of those pocket rockets as a second car.

BUT the BIGGEST and most DAMNING evidence and weapon in my arsenal on this holy crusade of keyboard warriorness, is the sole remaining fact that numbers sell! And in my years of being bored at work reading car forums, I have learnt that nobody massages a dyno or bhp figures like the masters at APR! So should another tuning company come out with higher figures then they do, I automatically cast doubt on it.
