Hybrid results {confusing}

Recommended Posts

im sure a big company like garrett could sort something out

there probably the boys to talk to I guess or turbotechnics

 

in terms of spool is there a lot of difference in hitting positive boost, the thing that worries me is the reliability thing

 

Talk to turbotechnics about their top of the range hybrids and if they have a Garrett GT2860RS 'Disco potato' 62 trim compressor wheel. Its much better efficiency at high boost than the 'standard' hybrid compressor wheel used (a Garrett T04E 60 trim). This means high boost with less temperature :D

 

Don't know if anyone uses the GT2860RS compressor yet. Anyone else know what's in their hybrids???

Very interesting thread, I was thinking about going for hybrids when my stockers died instead of a single, and I think this further strengthens this argument.

 

If I am "making progress" on a nice sunny afternoon and terrorising the traffic then I am normally pushing in 2nd and 3rd on A-roads, not 4th and 5th on dual carriageways... All the dual carriageways and motorways round me have an average speed of about 40mph!!!

Erm, I think Ian has said far more than I could about these hybrids. The set I've got are the set that Ian is talking about. I fitted them about 16 months ago after he sold them. They've not been rebuilt - they don't need it - there's no play in the spindles and there's no leaks in the seals - they're all good.

 

:)

 

I wasn't suggesting they needed a rebuild :) , just wanted to know who did the original turbo remanufacture/rebuild into current hybrid form..... which turns out according to Ian that they're of a mystery company. :search:

 

Guess we'll never know now, TurboTechnics replate their remanufactured turbo's so i assume it wasn't them.

 

Think Leons thread's been Hijacked quite enough eh, get some control over those 550's matey.

And I take it these internals will fit not compromising structual integrity of the turbo in any way, im after as reliable set as poss with the most efficient output in terms of power and excess heat, I know obviously more power = more heat but you know what im getting at ;), I guess I had better drop Turbotechnics a email and start my research:mail:

Ive heard of this 'potato slicer' type turbine blade before. Can anyone tell me what this means? Is this where each blade is in effect 2 blades?

I spent a couple of hours setting up the boost controller to get my newly rebuilt UK spec hybrids up to 1.0 bar must say it took settings of 65 and 65 gain on my SBC I-colour, so i'm wondering if there is a slight leak, i was also letting the EMU self tune but still had AFRs in the 10 s:( , but the overall impression was that they take a fair bit longer to spool up, and the increase was not that much, needed third and foot well down to get the boost up there as opposed to the J spec turbos, which are very quick full boost by 3000 RPM, but its early stages yet;) then my FMS went, so have to fix that first, but i'll add some more when its sorted.

Full boost on j-specs by 3000 RPM? I was sure 2 came on song at 4k RPM, maybe i need to take another look at my Rev counter or is that cos your TTC?

as Rob mentioned Leon, Dodgy is about to sell his S-AFC if you decide to go this way

 

out of interest, you were also speaking highly of a certain tuning company on Saturday, was this the same company who advised you that you didn't need to trim the fuelling with the 550s?

 

i knew something had to be wrong with the setup on Saturday as i just couldn't see you gaining anything hardly on me down the strip, when i was expecting you to catch up/pass me before the finish line

I dont have a problem with the company that works on my car. I still think they are very good. I just think a forum like this is priceless in people that might have shared the same problem pointing you in the right direction and taking the shortest route.

personally, i'd be a little bit anoyed if they'd told me the same, only to find out the opposite, along with some highly respected specialists on here recommending you shouldn't even drive it in that condition?

it was only revenge for Elvington :p i've got CW decats, aftermarket exhaust, running about 1.0-1.1 bar with a restrictor ring (never really see more than about 14/15psi on my boost gauge), an Apexi induction kit and an improved earthing kit

 

the new front mount is sat in the dining room waiting to go on :D

Err, not that I'm aware of :D I'm waffling on about the compressor anyway :p

 

Its just a more efficient compressor wheel from the GT series of turbos (the more modern types of Garretts). It has a wider compressor map, so is more useable than earlier types with narrower compressor maps.

The "Disco Potato" turbo GT28RS was so named by the development people at Garrett, due to the compressor map looking like a potato chip apparently.

Sorry, I should have said that in this context, the compressor is the turbine. I was just curious as to where the term came from - I'm sure there is a reason for giving it such a strange name.

 

Take a look at the shape of these blades and see what I mean.

Ian C.You are the man.You helped me last year when i fitted hybrids(blown turbos)as did Kopite;thankyou both.Have fitted PE 650 injectors,Aeromotive FPR,and a Greddy e-manage blue.Together with a 3 core Greddy intercooler,Walbro pump,full de-cat,Apexi N1 exhaust and air intake,plus a boost controller,car is going flippin' great!Even with RLTC,there are moments when the rear end will really step out. That said if i had the gelt,i'd have a PHR stage 2 single.At the moment though,there's bugger all wrong with hybrids:)

Never thought of that :D Strange.

 

I think it looks more like...... well, this isn't NWS so I'll let you decide :Pling:
