    EFR BorgWarner Turbo

    BorgWarner turbo technology has left Garrett behind - Garrett is still catching up with BW extended tip technology with the Garrett GTX range.

    The BW VNT turbos replaced the Garrett VNT as OE in many euro diesels, and Garrett has no answer to the BW staged/sequential turbo used on the latest euro and north American diesels.

    Now BW have a range of EFR (Engineered For Racing) turbos designed from the ground up for optimum performance from a single turbo - no compromise by basing it on OE turbos. The aerodynamics and materials are state of art.

    This link to a pdf file about the EFR turbos makes interesting reading.

    Not all VNT turbos are manufactured by Garrett, which have that reputation.

    There has been some discussion about these new BW turbos on the comp diesel forum and apparently there have been some issues - I haven't had time to look it up yet. The new S400's spool up very quickly - faster than earlier models with a smaller compressor wheel and they don't have all of the technology of the EFR.

    I haven't had any doubts that BW are ahead of garrett in the game, especially for diesels (garrett chase ricers mainly). But where Garrett do excel is with the information and flow maps they freely publish.

    Of course VNT's are an area where garrett doesn't give out this information.

    The document that I posted a link to has the compressor and turbine maps for the range of EFR turbos.

    Garrett don't give any info (maps, part No's, etc.) for their VNT's - I presume (just my wild guess) because VNT's are only produced for vehicle manufactures and none are sold for after market use.

    Indeed, it took me a while to get through it, serious amount of information in there.
    Thanks for sharing it.

    John, do you have any info on suppliers or approximate prices?
    (EDIT - have found some prices here: http://www.diesel-plus.com/turbo_sea...rgWarner%20EFR )

    Which option do you think would be best as a single turbo for a 4BD1T - let's say I was after 250 flywheel Bhp maximum.

    Another useful turbo calculator that I have experience with is the one from Squirrel Performance. This uses the methods advocated by Garrett - input engine, etc. details, your target HP, BSFC (0.36 for intercooled diesel) and air/fuel ratio (use at least 18.5 to minimise smoke). It then calculates the amount of fuel required to achieve the target HP and the airflow and boost pressure to suit the A/F ratio, etc. at various rpm, and optionally plots the points on selected compressor maps.

    I haven't played with the BW MatchBot calculator, but must do (when I have more time).
