3.6 liter Kenny Bell

Chancey · Aug 13, 2019

I was reading in an old 2013 Shelby magazine article today that Shelby doesn’t even crack the valve covers on the 2013 GT500’s for the 850hp Super Snake upgrade. The article states that because the stock 5.8 trinity is designed for high boost for extended periods, they just add the optional Kenny Bell 3.6 liter supercharger and the upgraded cooling system. Now since they warranty the setup and set up the super snakes like so, why cant we just add the KB 3.6 and upgrade the cooling system for the same 850hp, home made Shelby? Am I missing something here, or is it that realistic and easy to have our 2013-14’s make a solid 850 crank / 750-770 rwhp and be rather reliable at the same time?

I did 740 whp on pump with a 3.6 on a 5.4 with stock lower. 850 at crank seems pretty reasonable with additional cubes of 5.8.

Klaus do you think the internals would hold up if you didnt keep it in redline or over abuse it with this upgrade? Thanks

You could easily make your own 850hp on your 13/14 gt500. All you really need is bigger injectors, boost a pump and your kb 3.6 kit with throttle boady.Tuned by a good tuner.

I think anything over 700 is pushing so I chose to build mine. Also, it is kind of a waste since you are hardly spinning the 3.6 at those levels. You could probably make the same power with a 2.9 on a stock lower w/ upper and lower pullies. For sure on a 5.8. You might even be able to do it with a ported eaton although someone else will have to chime in.

People are doing this, for many years.
Although I wouldn't on a " canned " tune..

Yes you can make good power with the 3.6KB, I loved mine. But it's a fairly expensive supercharger and you'll need to get the super snake hood, or a Shelby1000 hood or lower your engine to clear the stock hood. If you plan on running pump gas I wouldn't push it past 750whp.

I personally made 827whp with my 3.6KB on my 13 GT500 with E85 and full exhaust and Lund racing remote tuned the car. If you really want to go that route I would give Van @ revanracing a call, he's a KB dealer and can setup you up with everything you need.

You can definitely make 750 wheel with a ported Trinity, or a 2R. No need to go with the KB if that's your goal....you're going to spend a boatload of extra cash going that route.

Something else to consider is those are usually rated at the crank. So it's probably 850 at the crank. Which is low to mid 700's at the wheel I'd say.

Also keep in mind that all 2007-2014 GT500 Super Snakes are required to meet 50 state emissions when they leave Shelby (or an authorized Super Snake modification center, Tasca etc.), so that 850 engine HP is blowing through cast iron log exhaust manifolds and the only exhaust changes that can be made by Shelby as part of the Super Snake build is the catback.

Am running a 3.6L on my 13 gt500 with stock bottom end at 847 to the wheels @17psi. Been racing quiet a bit for the past months no issues here just depends on the tune and of course how you drive it. One thing I don't do is redline her. Knock on wood she stays in one piece lol

You're making some great power, I miss having a 3.6KB, they really are badass superchargers, what fuel are you running and who tuned your car?

Am running e85 and I got it tuned here in Las Vegas NV by this tuner named Carl by Dyno Jet he tunes all Mustangmanny customers including his cars.

Oh nice, I've heard great things about him.

Yeah am still debating on keeping the blower. Am currently on the process on building the motor and possibly thinking on going with a VMP Gen 3 or gen 3 R. Had a 3 inch carbon fiber hood loved it but I miss my oem hood.

Norton · Sep 1, 2019

700+ RWHP is possible with simple bolt-ons and a good tune.

Don’t blame you about missing the OEM hood. Thought about the Shelby 1000 hood but still want the stripes. Never see a Shelby 1000 hood with stripes.

I vote keep the 3.6 KB.

Look up @Dimas_SVT on Instagram, he has a Shelby1000 hood with stripes.

Bearbo · Sep 1, 2019

Thanks. He has a beautiful Shelby. I still think Grabber Blue with Black stripes is best looking combo for a Shelby GT500 but Dimas Shelby was drop dead gorgeous.

I like the Shelby 1000 hood with stripes. Think I will be getting one.

Guys here on the forum are making 850fwhp with stock Trinity & bolt ons. That's 720-725rwhp on a Dynonometer thru stock 3.31's. If that's the goal not sure if it requires the KB 3.6.
