    • Garrett releases G30-900 turbocharger capable of 900+ hp from 76mm compressor wheel - New G30-900, G35-900, and G35-1050 turbochargers

      Garrett is making some bold statements here with their three new 'mild frame' G30/G35 turbochargers. You have the G30-900, G35-950, and G33-1050 which Garrett states do not have an equal from the competition at the moment at the moment.


      The G30-900 will likely be particularly interesting for BoostAddict readers:

      The G30-900 is a 900HP Capable turbocharger developing this power from a 76mm compressor wheel - no turbo manufacturer has anything in their arsenal with this capability or even close to this unless you go 4family sizes larger! The turbine wheel remains the same being 55mm exducer with a 60mm inducer - the direct comparison size for size is the Precision 5862 which makes a mere claimed 700HP - which is nowhere close to the G30-900. The only Precision turbo that can produce the same power output is the 6466 which has three times the lag and twice the physical dimensions and weight!
      On paper it crushes the Precision 6466.

      Also to be noted is the physical size is much smaller meaning tight engine bays trying to fit a powerful turbo may have their dream solution here.

      G35-900 and G35-1050 details below.

        So a...

        6255
        6262
        and a
        6862


        Supporting that power... Hmm sounds good on paper but that's a lot to ask for such a small turbine exducer and limited a/r options... Especially at increased engine displacement.

        Hard pass until proven otherwise.

        Even XONA's 68mm is running a 69mm turbine.

        People seem to think the turbine exducer is too small but I mean isn't the idea here that the turbo can support 900 hp in a small package with good spool?

        I'm not so sure you would say it crushes a 6466. It flows 10lbs/min less. At the end of the day you are spinning up mass you can't get around that.

        At 35psi is flows 80lb/min on the 60% efficiency island and basically on the choke line. You generally dont want to be below 68% or so they say. Not exactly amazing. I would call it a 800 hp turbo as it flows 80/lb min max and you give 10hp per 1 lb of flow/min. So you are comparing a 90lb vs 80 lb turbos.

        All of these new garrets are pretty bad ass. You pay for it but they are sweet. The new g25 series would be perfect for a twin turbo n54: https://www.garrettmotion.com/racing...eries-g25-550/

        I think their size it what is most impressive and right sized for sooo many applications.


        What efficiency island is the 1050 on at 100 lb/min? I'd take a BW 9280 over it any day of the week.

        In spool and packaging for the output...

        I will give you that. Their whole new line is 'right sized' in both packaging and output etc. Very efficient.

        I think garret is a bit aggressive with their hp ratings as they are above their lb/min max on the compressor maps.

        The G series literature assumes the engine will net 11hp per pound mass flow, vs all other literature at 10hp per lb. If your comparing "Hp" as your units, the garrets are artificially 10% inflated.. "dynojet" of turbo maps.

        Reverse rotation, that will make for some nice packaging.
        I want that.

        They are probably assuming the increased efficiencies of modern engine technology, but they should stick with the standard calculations for a more realistic comparison.

        Yes, that is an awesome option! Not only will it allow more fitment possibilities, but a left & right Twix turbo looks great on a TT setup. Click here to enlarge
