    • 3.8 liter Gen 5 Whipple twin screw supercharger coming for the 2020 Ford Shelby GT500 5.2 Predator (and Coyote)

      It is amazing the pace at which the domestic aftermarket moves, isn't it? The new 2020 Ford Shelby GT500 Mustang just hit the streets and already it has a plethora of tuning options with much more on the way. You can even add a larger twin screw supercharger swap to the list of parts coming.


      A 3.8 liter twin screw is huge and absolutely dwarfs the factory TVS2650 by over a liter of displacement. The thing is, the factory blower is plenty capable. 1000+ wheel horsepower will easily be supported.

      What makes the twin screw worth the swap? How much power can it support? What does it cost? Will it take a built motor and transmission to begin to take advantage of it?

      The TVS2650 is extremely efficient and the twin screw likely will not start showing a flow advantage until very high boost levels.

      We will have to wait and find out.

        Then it would only make sense with a built motor to capitalize on that extra boost and big power.
        stock motor isn’t taking 1400whp on e85.

        Maybe 5% of GT500 owners will even use this beast of a blower. The stock ones good for a 1000whp.

        I think we'll see ~1200 out of it...

        You’re probably right sticky. I mean even at 1000whp how can you even enjoy the car on the street? 4 seconds on the throttle and you’re at warp speed, that or hitting a ditch ��. Now if ford can just put the DCT in the gt350 then I’d be all over it.

        Ford dct needs a stand-alone controller before swapping into anything but as fast as the domestic tuners move I see it happening

        Would be awesome. They almost have to do it. The reviews on the DCT so far are super positive.

        it be such a missed opportunity IMO. The motor and chassis are such track thoroughbreds, the cars begging for a DCT. I’d have to imagine the DCT would get the gt350 down into the 11.8s range on the right strip.

        I understand why, from a lap time perspective it would make sense to put a DCT in the GT350. However it's my understanding that the GT350 is built more to be an enthusiast's/driver's car and not purely be about setting the ultimate lap record. If it was, surely they would have just built the GT500 instead and done away with the stick and flat plane crank motor of the GT350. Therefore I wouldn't be surprised if the manual remained the only option for the GT350 for a while, unless they discover some large untapped market of GT350 DCT buyers just waiting in the wings.

        They already developed the DCT though. Might as well offer the option and to give the GT350 some new life.

        Very true. They continue to update and improve the cars, for 2019 they substantially changed the GT350 (non-R) to make it far more similar to the R in terms of handling and responsiveness. So the DCT may be the next change for 2020 or 2021.

        It's the logical thing to do.
