Latest mod pictures...my hybrid Ibiza - now sold!

[Gibon]

The right compressor from GT2052V Turbo. There are 2 different wheel designs.

To implant the bigger turbine in GT17 housing, there is cnc-machine work required.

Greets, Alex

2 different wheel designs ? OK. I didn't know.

[philsip]

i could be wrong but i think he means the stage 1 hybrid with the upgrade bearing but same size impeller or the stage 2 hybrid with the 20vnt impeller fitted to the cnc machined 17 vnt impeller side?

Even though that doesnt change reachable hp...

I like the sound of being called legend lol yeah mine is so loud, loudest I've heard yet, and a few neighbours have actually made complaints lol, police came round and said the exhaust needs to be removed cause not having a cat and back box is illegal, after I told them no! Go do one and research about diesels they said my exhaust is legal and I can keep it, me 1 cops 0 lol, I'll get a video clip up soon mate

I love it when the police think they can act all high and mighty - and when you actually use to law to prove them wrong, there is nothing more satisfying!

LOL, thats a good one.

You will never ever get 240-260bhp out of any hybrid done from a GT17 hotside.

The required mass air flow and thereby showing up exhaust gas amounts outflow the GT17 turbine @ about 210bhp.

Even VNT20 turbine is way to small, it is only a few (8) % over GT17VB turbine.

For 240-260bhp you need at least GT22 turbine and to have clean combustion you need at least 59 or 60mm compressor.
If you dont bother smoke, you can get about 235-240hp with 56mm compressor, but this is with lambda 15,5:1 so it will smoke very well*g*

Torque btw comes from injection quantity, not from decision which turbo is used.

And btw nr2:

To big compressor with to small turbine causes boost creep which can only be solved by reducing injection quantity.
You can see this even on "standard" GT1752V hybrids, the duty cycle for N75 will be @ 95% @ about 3700-3800revs, upwards from there there is no more possibility for vnt mechanism to reduce boost, only way to reduce=reduce IQ.



Greets, Alex

Jeez you know your stuff! Or you use the right words!

i've been reading this thread all week on my mobile, but not had chance to post all week (would take to long on my phone)

i may be going over old ground here as i understand that you've sorted it with the relevant parties and i'm pleased that you've got your car running, on stage 1 remap and i admire your persistance in going hybrid, but as going hybrid could be an option in the future i got a few questions......



it was the wrong turbo hybrid'd & fitted
IMO, thats a bit of a fook up and personally i wouldn't be overly impressed at paying for, IIRC did you say ~£1500, on parts and services when they were wrong!!!
so has what you have spent to date been refunded or has it been put down to experience?.........

I didn't realise the turbo was wrong until it was removed to check that the turbo was in full working order. I'm going to get slated for this as I have for everything I've said - but I'm answering your question. I expected what I paid for to be put on the car. The company involved said that they sent off a PD150 turbo and a hybrid PD130 came back. I'm not a turbo man, but I am sure that the PD150 turbo is quite a bit bigger than the PD130 - so how a company that do these mods on a regular basis didn't notice the difference I honestly don't know. But that's not for me to question. Surely - you'd check that it was the right turbo before putting it on the car? Or is that just me being critical?

The money I have spent has been refunded. I couldn't have afforded it to be put down to experience!

now regarding mapping.
call me niave if you must but i thought that when a hybrid was fitted, a custom remap was created for that cars setup utilising every possible mod to get the best out of the car.
but i've read all the posts as saying the map installed was for a different turbo
so is custom hybrid mapping, not that custom and more of a generic map like a stage 1 or is it more of a case of installing a base map then tweaking it from there to utilise mods, a bit like a stage 2 map?

I'm not sure that it WAS the wrong map, but I was made aware that the overboosting was being caused by the wrong map being put on, and with the PD130 turbo being smaller, too much pressure was building up inside the turbo which therefore caused overboosting. Whether this would happen or not I do not know as I dont know enough about that sorta thing to comment....

The other thing I will say is, surely if my car was rolling roaded then the company/mapper would've clearly noticed that my boost gauge was winding right round, and indeed off the gauge! As if it was down to the map that it was overboosting, then this would've been happening from day one. I never got the rolling road printouts so didnt really know what my power was. I was told one run was something like 217bhp and 330ft/lb and the other was 230bhp and 312ft/lb or something. Even though the turbo that was on my car (the stage 1 PD130 hybrid) was only capable of 200-220bhp according to Turbo Dynamics themselves.

The company that did this work had "hybrid" a Mk4 Cupra tdi not long before mine, and he has EXACTLY the same power figures that I was told I had. So either this is a mega co-incidence, or I had the same map put on mine, or I was told his figures thinking that I wouldn't find out what they'd got! It all seems a bit weird.

what happened regarding this post below?

did you ever find out what the cause of this?
has this been rectified, has it caused damage to anything else?
have other parts failed because of being put under excessive stress?

*Edit - just noticed the post you mean! I presume it must've been water on the cambelt or something! Not unless a nut/bolt hadn't been done up tight when the conversion was done and it dropped down onto the belt and got beat around the engine bay a bit - but there's been no trace of this noise since so I cant help but think something must've just come off that hadn't been put back right. Not sure! I'm not aware that any damage has been done to other parts. Yet.

No other parts have failed due to the excessive stress as far as I'm aware of! I'm so surprised I didnt get a boost pipe pop off when it was under 35psi of boost! Goes to show I do my jubilee clips up "man tight!"

regarding turbos, now i didn't realise there was a difference between a hybrid'd PD130 & PD150 turbos i thought that once hybrid'd they were the same unit
what sort of power difference figures are we talking between the 2 differnt turbos?
and you say there are different stages of tune, again whats the difference in bhp and torque?

just for clarity, these are mearly questions and not digs at any relavant parties.........

I wasn't aware either - I thought the GT1749VA and the GT1749VB were the same turbo housing, but with different internals and that both had the same power capabilites once mapped. I have since learnt (I believe) that the PD150 turbo housing is bigger than the PD130.

Turbo Dynamics claim 200-220bhp on a PD130 stage one hybrid. Then 220-240bhp on a stage two PD130 hybrid.

On the PD150 hybrids they claim 220-240bhp on a stage one hybrid, the stage two PD150 hybrids are claimed to produce 240-260bhp. So there must be a difference. The same work is done to them both, although a larger compressor wheel is fitted into the PD150's which therefore must mean it's bigger! I cant give you the torque differences as they only quote bhp on the Turbo Dynamics spec sheets.

I hope this helps!

I have the turbo spec sheets, if you want me to write up what's done to them all then I will be more than happy to! Hope this has answered a few of your questions. I'll no doubt be in the wrong for answering them but as you say - they're mearly questions and not a dig at "relevant parties."

 

[majesty78]

The diameter difference between GT1749VA (131hp) and GT1749VB (150hp) turbo on the hotside is 36mm exducer on the VA and 37,6mm exducer on the VB.
Compressor is not relevant because its no longer used in a hybrid device.

Anyway this hotside difference do never cause such boost problems.

yeah, thanks for the honest response!
glad you've not ended up out of pocket on this.

agreed, unless you were going to take the turbo off yourself and check it over for part numbers, how were you to know?

looking at those power figures TD quote, i can see why you want a PD150 to hybrid
i would be interested to know what is done to a turbo when it gets hybrid'd, if you got time to post up the details

oh and what brand of jubilee clips do you use and where do you get them from?

To be honest, if I didnt have that £20 boost gauge in my car, I'd still be driving around today not knowing anything was wrong! All I can say is, that boost gauge has saved me ££££'s! Cos I wouldn't have known until the engine went pop, or the turbo blew up. And I'd have been so out of pocket it's unreal!

I will get the turbo spec sheets and write it all up for you.

Jubilee clips are just Jubilee Clips. The say something about being high grip on them I think. But I crank them up pretty tight. So think that might be the reason why. Broke a few cos I did them up so tight!

Can't do them too tight otherwise it might split the silicone. Right - off to find the turbo spec lists!

Just some new pics to help lighten this thread! I bought me a digital SLR camera yesterday so set about taken my first few pics! I'm totally new to the whole SLR scene so I'm learning!

I hope your not using the camera in Auto mode, Ash What carera did you get?

Auto mode is for wooses.

It's a Sony AX350. 14.2 mega pixel, got quite a few gizmos. Just need to learn how to use them all!

Nice camera bud

Have a look at these sites vlivky, and clicky, and do some reaserch on HDR photography

Tbh I'd heard that Sony's arent as good as Kodak for example, but this camera is apparently quite new out and it's won best camera award or summat. And for someone that doesn't know too much, that swings it.

I have a rough idea how to do HDR pictures. You do one underexposed, one normal and one overexposed, then layer then all on top of each other i think?

Sony do good DSLR cameras but the only thig with them is that you have to use Sony only accessorys (lenses, flashes etc).

Yep, for HDR you need at least 2 pics with different exposures but I find 3-5 different exposures give you the best results. I use Photomatix to convert into HDR.

the SEAT Sport FMIC looks fooking massive behind the grills
why didn't i buy it

have you noticed any difference from the Forge

I'll have to get a stand and give it a bash! Thanks very much for your help!

It IS massive! And I haven't noticed any changes really as when I fitted it, it was running "bad hybrid" so I couldnt use the throttle. So I was 3 weeks without being able to use the throttle, so now I've gone back to remap, I cant really remember what it was like before!

But even for looks.....certainly gets noticed now!

I'm using one of these clicky, and it does a very good job (ps. PC world do them cheaper).

If you need any help with it just give me a shout bud

Just thought - what I have noticed is that the Seat Sport is SUCH better quality! The fitment, the build, the pipework routing is MUCH better, much simpler, much more direct with no sharp turns like in the Forge kit.

The forge pipework is so much more insecure - I dont know about yours but mine used to wobble a bit, and I had to cable tie it together - not good. This pipework is pretty firm and I think it looks bigger bore than the Forge Setup. The inlet/outlet on the IC itself are MUCH bigger than the Forge setup.

I'm using one of these clicky, and it does a very good job (ps. PC world do them cheaper).

If you need any help with it just give me a shout bud

Ok will do! Cheers for that!

 

[majesty78]

By the way, the Seat Sport FMIC works much better than the one from Forge.
