    Fast Attack Motorsports building largest BMW S85 V10 at 5.9 liters

    BMW S85 V10 stroker and bigger bore builds are nothing new but Fast Attack Motorsports is building the largest S85 V10 BimmerBoost knows of. Many S85 stroker builds top out at 5.6 liters maybe stretching to 5.7 but 5.9 liters is new territory.

    Fast Attack Motorsports is claiming to get there with a bore of 94mm and stroke of 85mm. This adds up to 5898cc.

    The factory S85 V10 bore is 92mm and the stroke is 75.2 mm. This adds up to 4999cc.

    Adding almost a liter is a huge increase. Dinan goes to 94mm bores for their S85 and S65 builds but the cylinder walls get very thin at that point. Do not expect to be able to throw any boost or nitrous at this S85 V10 if Fast Attack Motorsports even succeeds with the build.

    Fast Attack Motorsports you may recall last year also stated they would pair the S85 V10 with a DCT transmission and control it through the factory DME. This has yet to be done.

    BimmerBoost hopes these projects succeed and do not just fade away as many tend to do.

    It's hard to know without proof but those Troy Jeup motors sure seem to be hit or miss.
