uff¡¡

sorry¡¡ duplicate post¡¡

please moderators delete this post and he first one duplicate

[Rocco]

are you not using the chip set from hoffer ? which injectors are you using ? you should be inthe 11s i think ,a custom map would sought things

hello again Andy

i am not using the Hoffer76 chips because my car it is a 3B and the chips are for AAN,ABY/ADU i think

i am using all the same parts and software for use them with k24 7200...and now working with the Hybrid k26/27

today afternoon i had an other 10kms of closed road tests and saw that the AFR shows me whem pike of boost 12-12´3...yes always,and whem the boost it´s going down after full boost the AFR numbers starts to going lean progressive : example less boost = leaner AFR numbers like 12´5,12´6,etc... and cruising of course around 14´7

hope it helps Andy¡¡

the turbo gives less torque in the low rpm´s than the RS2 one....and starts to load well since 3000rpm...and full boost by more or less 4000rpm

it is funny

today i made some pictures of the turbo installed...but now i cant upload them..and aniway there are very few to see

unfortunately here in Spain i cant do any cusom remap for my car... here the tuners dont know nothing about our cars.. stupids¡¡ and then i dont know what to do now...

tomorrow i will try to use my "apple" green injectors 440cc/3bar....and see how the car feels and AFR numbers again... it will be richer for sure

numbers between 11 and 12 would be the best true??

Sorry didn't make it clear, those pics are of my car when a K26/K27 was fitted. The 3076r is way bigger so big it can only be removed either by removing the engine mount and jacking up the engine or removing the manifold to turbo studs

thanks for answer Jamo

OK...if your picture it is of your car whem had k26/27 was fited,then my current turbo it is a real k26/27because it fits like in your car


what do you think about 12-12´3 under full boost 1,6bar??

dangerous true??

i will have to change something

well....after see the pictures of these three turbos i think that my hybrid coldside it is not big as the k29 compressor

BUT it is complete sure that my turbo fits the coldside like your turbo in your picture installed

OMG¡¡

Jamo,i had in my hands today k24 7200,k24 7000 and my hybrid xxxxx

my coldside it is 99%similar like the k26/27/29 turbo in your picture

maybe i am confused...but looks very similar if we compare it with the RS2 coldside

in the turbo parts ,we can read leters and numbers...but i did not write them for ask now if they are an other turbo

,how many HP can make a k26/27/29 in our cars??

i will advise to Hoffer76....may him it is complete sure that my turbo it is a correct k26/27

[Rocco]

I ask as a K26/K27 is only a little bit bigger than an RS2 there was no spacing issue on my car unless you have a bigger compressor which means more power

Jamo¡¡

my turbo fits 99% as your first picture shows

this is your 3076??

tomorrow i will make pictures and i will upload here

i´ve drove my car only 10kms,testing how it feels and works.... with my S2 3B to RS2 step setup...software too of course...and i had around 1,7bar in 3rd gear "foot down" since 3500rpm and holding my foot down very few time (scared)...

i need to continue testing more the next days..but the first AFR numers were around 12-12´3 under boost,,,that it is "some bad" true?? i am not a chip tuner... i am using 98 ron fuel....


it is dangerous 12-12,3AFR''??

[quattrostyle]

well we'll see, must get a damn 90 quattro first

[Jamo]

Don't know the Rs2 compressor is small, it's a small turbo but packs a mean punch

[quattrostyle]

hmm the outer dimensions of my RS2 hybrid are equal to the S2 turbo I got. Dimensions of the wheels differ a bit:

Hot side S2: 45 mm.
Hot side RS2 hybrid: 56 mm.

Cold side S2: 47 mm.
Cold side RS2 hybrid: 48 mm.

Is this correct? Hope it is capable of 380 bhp...

[Jamo]

sorry to hi-jack this thread. But what about a RS2 turbo, should the outer dimensions of the cold and hotside be larger than a standard S2 turbo? Because mine ain't.

[Rocco]

Have you got a K26 manifold? the Wagenr manifold is actually 10 mm closer to the head than the rs2 oem so a 3076r coldside will fit.

Sounds like you've got a K29 compressor as the K27 one isn't big at at all not in comparison to a Garrett

yes my wagner manifold it is K26 and of course the hybrid turbo it is K26 flange

i have not idea about your gt3076... you have the same Exhaust Manifold with T3 or K26 flange??

i dont know if my compressor is K29,i will have to ask Hoffer76 forum member who selled me the turbo...but surelly it is a Hybrid K26/27 with 360 bearing as Richard (HOFFER76) said

i will do pictures the soon as possible
