Twin Turbo
« on: November 04, 2009, 09:38:38 pm »
I'm sorry about my lacking of engine knowledge lol but what is it that makes a twin turbo so much better than a turbo and is it possible to have a twin turbo fitted on a GP Abarth or is that what the difference with the esseesse kits turbo (its a twin turbo)?  ???

    Twin turbo means u have 2 turbo´s. Esseesse has a bigger turbo than the "normal" Grande Punto.

    twin turbo for example: when u have a V6, u could have 2x 3 cilinders, and each of the 3 cillinders gets a turbo: 2 turbo = twin turbo. Means every cillinder gets more air then if u get only 1 turbo for 6 cillinders ;).

    Pardon my bush english  :-\

    Cheers for the explaination, so you can't get a twin turbo for the GP Abarth then I take it?

    It depends on what you want to do.

    You can have the turbos in parallel - e.g. one turbo for each bank of a V eninge (like already mentioned)

    or

    You can run them in series.  BMW and others do this on some of their diesel engines; they have a small turbo that acts lower in the rev range (less lag) and then a big turbo takes over at a certan point for the real 'ooomph'

    Not a very technical explanation but I think it explains it well enough.

    For your Punto id say its not really worth it - if you want more power just change the original turbo for something that blows more air!

    Just one other point, two smaller turbos can spin up quicker than one big one. So there is less 'lag' something on older turbos which spoils the drivability. You put your foot down and have to wait until the turbo gets up to operating speed and provides the boost, the all hell breaks loose  ;D as you get the boost in a sharp spike.

    A four cyl engine isn't ideal for a twin turbo set up - they are best for inline 6's (Skyline, Supra) or a V-engine. Only twin turbo four banger I can think of is the Saab/Lancia tTID diesel. Quite often people get the concept of a twin scroll turbo on a four cylinder mixed up with having two turbo's.

    Or use a compressor with the turbo? Compressor for low revs and turbo takes over in higher revs when i am not mistaken. Almost to none turbolag i guess. VW/Seat uses that??? Don´t know about the costs.... Guess i dont want to know XD.
    There are better options to gain more, esseesse (with better brakes and stuff!!!) for example or chip, or different exhaust line with intake line, or or or? More bhp isn´t everything tbh.

    You really know your stuff  :thumb: as the the esseesse kit though I've heard sooo many people sayit hardly makes a difference to standard, even someone say they were asked by someone with one fitted when they had there's fitted when they didn't even have one, £4000 seems a lot of money with not much if any gain

    It all depends what your comparing it to really.  The power to weight ratio is not very high in performance car terms.  At best I would describe it as nippy, but really thats all it's meant to be. 

    Maybe nobody has tried to beat you off the mark yet? It will happen sooner or later especially as traction from a standing start is not exactly brilliant.

    It's still quite a fun little car though..... enjoy  :thumb:

    Cheers I definately know I've had a few people try to beat me off the mark but most of them have been just kitted up Citron Saxos, peogeot 106, Fiesta XR2i TBH but also quite a nice BMW which was pretty proud of lol.
    But defo agree with the traction from standing elpecially on a night like tonight when it hasn't stopped p*ssing it down where I am lol

    I have a GPA SS and it is nippy, just like small Italian cars should be, but I wouldn't describe it as rapid.

    I also have a BMW 535d (twin turbo 3 litre) and this sort of car (diesel, heavy, torquey with a lot of power after the mid-range) suits the characteristics of the twin turbo well.  I don't think it would suit the GPA - the SS turbo kicks in pretty low down the rev range as it is.
