My agu k03s on a custom map runs 241bhp and 246 lbft torque but I've heard that i can get abit more by getting yellow calibre injectors or saab red injectors, vr6 maf housing 2.75" and using my 1.8t sensor? 255 fuel pump, forge actuator with a yellow spring and get the map tweaked is this true? is it worth it and will i get any more gains? (im after bit more torque really)
-
I have seen people with a bit more low down torque around 270ftlb but it also varies from engine to engine, buyin all them parts is a lot of money and I your unlucky you may only a extra 10-20 ftlb of torque ....
-
kin ell that must be pushing the standard injectors :shocked:
Mine runs slightly lean on 225bhp :huh:
I would fit the injectors/pump/MAF for safetys sake. Who mapped it mate?
-
Sort just noticed you put agu k03s :grin:
My mistake, you probably will need maf and injectors, fuel pump will depend how good your is

Woody from east coast tuning, where can i get the injectors/pump and maf housing? if i change the maf housing will i have the change the silcone TIP or will i be able to squeeze mine on? and what about that actuator as im running a standard one?

how do you know if your fuel pump is good? and once i get all those bit do i get the map tweaked?
-
Cant see that running 241bhp without injectors, bigger MAF and fuel pump.
OEM MAF is out of scale at 233bhp ish.

I think really it's down to luk some are goo enough and some are worn and can't handle, dunno how you could test, I you jar te budget just get an uprated one.
-
depends on mileage with actuator, I changed mine as it was a little bit bent :lipsrsealed:
They're all old now and running higher boost shortens the life a bit too
Yes you'll need map tweaks so the parts will need fitting at your tuners, not before you get there

well it is its been on rr, same way you claim yours is running 248bhp 278lbft.
golfyste & wazzer: i'll get the bits and get it done any ideas where to get the fuel pump and injectors?
-
RR's are easily fooled. fact.
Theres very very little possible way for the stock injectors to run that much power. Even the stock MAF couldnt flow it.
Sounds like you dont even have a forge actuator on yet?
-
To be fair Chris had the MAF, injectors and fuel pump fitted to get that power.
Injectors and MAF can be had from eBay, also pump. There is a how to on here on how to fit one

Yes and i know that but most people are still gonna go by those figures because if u cant go by that or vagcom logs what can you go by?? how will you know what you've got? No point saying u cant get those figures by having a standard maf and standard injectors etc every car is different as u know some will map better than others, for all i know i could have uprated injectors who knows??. I read your post on club gti and not alot of people believe your figures but its what you've been rolled at and what you believe mate. I got a standard actuator on it aint uprated it yet , doesnt really matter to me if its running 225 or 240 just trying to see if i can get those torque figures up if i cant then i'll stick with what i have.

i know he did i read his post, cheers mate i'll look for the bits. Is it the vauxhall calibre yellow injectors or saab red injectors?

The thing is with the rollers mate is that many in the country read over but you will see chris had his done at r tech and they are know to have a very good (true) and reliable dyno.
The thing with the standard maf and injectors is that they cant physically get enough fuel/air into the engine to make them figures, no matter how well te engine takes to te tuning so no you can't get them figures.
You should uprate your actuator really as you may struggle to hold boost which will in turn lower both your power and torque.
And when you say you don't car about the power only the torque that seems a little daft really. Torque relates to power via a equation which includes torque and rpm so of you had loads of torque but not much power it would mean that your peakin torque low down the rpm but then loosing it all, which would be rubbish to drive. but if you held it the higher up the rpm range your power would also go up. So it's not just about getting a high peak torque figure its about getting and holding it as high as possible whih would in turn increase your power ....

Calibra yellows will do you mate
I've got all of the above ready to fit in mine but just need to sort a day to go up and get mapped

Sorry to jump in but has anyone got the link to a uprated fuel pump and maf plz..
