guys i have a problem...
I have an Evo IX with HKS silent hipower and an ecutek software!
on my belltronics gtech it shows 390 hp at the crank!!!
i tested an stock s4 with that gtech and showed exactly 344.08 hp... so i was thinking that it might show good!
in that situation...do i need a fuel pump?, maybe im runing lean?...(from ecutek i should be runing on 1.6 boost)
Thanx in advance!

PS. By the way ...i raced on 1/4 mile with the new RS4 (420hp) and i won with 2 cars in front!

 

Well youre definately not actually making 390 crank power. But yes when you get a tune it is a good idea to upgrade fuel. The IXs do have a bigger pump than the VIIIs but its better no to try to run them at a high duty cycle. A 90 dollar Walbro can save you thousands in the long run. Thats just my 2 cents however. The best maintance is preventative maintance.

 

Doesnt that gtech make popcorn?

Wouldnt take what that thing says for a grain of salt.

By a Wideband thats a btter investment and as the guy said before the Walbro is cheap and can save u

you shouldnt be running past 1.4 bar with no fuel pump.

 

Throw the GTech in the trash

 

that only holds true for the evo 8's. according to AL, the 9's have a higher flowing fuel pump and he guessed their flow rate to be 230LPH.

P.S: This is my 500th post. I am an evolved member. WOOOHOO

 

Thats exactly what I said. But running a IX fuel pump past 21 psi you are going way too deep into your duty cycle so throw away the thrashy gtech and get a widenband as suggested cuz they rock and while youre at it a fuel rail isnt a horrible idea either. The stock ones are known to lean the 4th out.

 

Offtopic question are you really from Romania?

 

The IX Fuel pump is pretty good, with just a reflash and an exhaust you should be nowhere near running out of fuel. If you think you're running lean (because of an improper tune), I would recommend a PLX wide-band 02 system. There's the base model and there's one that will detect detonation also. It's just a great safety feature to have!

As for the Gtech, I'd get on a dyno. That said I think the new PLX's have a horsepower feature also!

Cheers,

Thx a lot guys... nice info!
In the meantime i bought a ralliart dropin filter, a helix turbo outlet, a walbro fuel pump and a radiator cap from ralliart ( ...lol).
I need more info about PLX wide-band 02 system...
where do i plug it ? at the outlet o2...or the testpipe one?...or im mixing stuff and i dont know what the hell im talking about?!...

PS. 1.Yes im from Romania...
2.Gruppe-S...do u make shipments all over the world? Like ...Romania?
If so...what payment metod and with what transportation?
