Audi S2 2.0TFSI +500hp with GT3071..........

[Jonnybravo]

Thats a 2 litre on a 3071, custom specced cams and a well specced engine on top.

With the difference that we are talking about the GT3171R and not the GTX series that use other compressor impellers.

Rated by Gerret for max 480 hp!

No matter what combo you are using the ultimate restriction comes from the compressor inducer and the turbine exducer.

Classic GT3071R has a 53mm compressor inducer and it is almost impossible to brake the 500 mark with it.

You say 'we' are talking about the GT3071R and no the GTX series .
Where does it say at the start of this thread that he is not using the 58 trim gtx wheel ? ?

The gtx is the standard from garrett now on the 58 trim , so if you but a 3071 with the 58 trim comp wheel from them it will have the new gtx .

and what happen with the 0.63 AR?? is it possible?? and with the 0.82AR?? +550hp??

you are confusing comp AR with turbine AR , I was only talking about compressor wheels .

I give up.

In the video it just says -3071R , many people had GTX wheels a wile before general release , about a year ago I had a GTX wheel in my had looking at it, just depends if you know people at Garrett .

APR does +500 crack hp with a little better fueling and 2871 from that engine. But that's on 109oct racefuel.

It is a stunning engine, when it comes to efficiency, but I am 100% that pull was made with racefuel.

Mind we got almost 460hp from an ADU engine with 2871 like five years ago with pump fuel.

i really dont think the dyno figures are relevant, some time logs will do better.

i thought GTX only came out at SEMA this year for the 3071 and 3076 series. I think its impossible that they have a GTX billet wheel turbo there already
