NOW AVAILABLE: JHM B8 S5 4.2L Stage 1 Supercharger Kit

Introducing the JHMotorsports Stage 1 B8-S5 4.2L Supercharger Kit!!!

The JHM Stage 1 Supercharger is hands down the most cost effective supercharger solution for the B8-S5 4.2L. With common bolt-ons and supporting hardware, we have repeatably achieved high 11 second quarter mile runs, with 118MPH trap speeds!! With performance like that, your seemingly unsuspecting two door German coupe becomes a definite force to be reckoned with.

FEATURES AND SPECIFICATIONS

a Our JHM Stage 1 Supercharger Kit for the B8-S5 4.2L will make 100-120 wheel horsepower (WHP) over your car’s current configuration. Your current modifications, the dynamometer (dyno) used, temperature, elevation, and octane of gas will all effect the exact amount of power gains.

Our Supercharger Kit features a Vortech V3 Si Centrifugal Supercharger Head Unit that is good for up to 800 horsepower! (Unchecked, this amount of power would be too much for a stock B8-S5 4.2L motor. Through our extensive development and testing process, we were able to limit the output of the supercharger to levels safe for the stock motor through hardware and tuning.) The V3 Si blower is a self-contained unit featuring quiet, helical cut gears. The only time you hear noise from the blower is at idle and low speeds. At wide open throttle, you hear nothing but the raw power coming from your JHM Supercharged S5.

The JHM Stage 1 Supercharger Kit also includes our JHM Supercharger Mounting Brackets that were designed and are made in-house. These brackets are made from reinforced steel, laser cut, and then powder coated black for a clean installation.

In order to insure the longevity and durability of the belt and pulleys on the S5, we upgraded the OEM belt and pulleys to a 6-rib system with our JHM 6-Rib Accessory Belt Conversion Kit. This Conversion Kit features 3 JHM Supercharger Kit specific pulleys including an Alternator Pulley, a precision balanced Crank Pulley, and a Supercharger Pulley good for 5 to 7 pounds of boost (exact boost levels will vary depending on your exhaust system, other modifications, and environmental factors).

Due to the compact engine bay of the V8 S5, we had to locate the Vortech Supercharger Head Unit off of the passenger side of the motor, below the headlight. We created a number of different proprietary parts including our JHM Supercharger Kit Silicone Inlet and Outlet Hoses. The Inlet Hose is made from reinforced silicone to prevent collapse under vacuum. The air intake is filtered through a JHM Supercharger Kit specific K&N high-flow, conical air filter.

We are currently working on JHM Supercharger Kit add-ons that will allow you to use more of the supercharger’s power capabilities. Stage 1+ (Intercooled with upgraded fueling and a smaller pulley, safe for stock motors). Stage 2 will require a built motor for engine safety and longevity.

Jake

If any of you automatic guys are local (or willing to ship) and interested, shoot me a PM!!

Looks like a great kit once again! Glad to see it hit the market!

Thanks!

Jake! 4 years ago I would have bought this and driven to you guys for the install

Lets talk about the plans to build the S5 engine~!?

… Still can! :wink:

Same as the S4 and RS4. Right now we are working on the next step which is inter-cooled and then after that it will be built motor.

Got it. any rough ETA? (I may bounce to a R8 V10) if its going to take another 4 :wink:

No ETA

But… if you go R8 V10 we have tuning for it… and exhaust…

Tuning for the new V10 and v10+?

How about built motor for the v10 :wink:

waste of $$$. car becomes too fast to enjoy like an UR turbo lambos are not balanced to hit the twisties.

Supercharged R8 V10 adding 250-300hp would be perfect if the motor can handle that ???

Glad to see this officially come out! Can’t wait to see the progression of this kit with the next stages.

Jake FYI, your “click here” link for pricing isn’t working though.

Will there be an intercooled stage 1+ version that uses stock motor? i.e. the RS4 kit that traps 120-121 like on the yellow RS4

Looking to get all of them!

That’s what’s in progress now.

I hear ya, but I was thinking a built v10 to handle the stage 2+ supercharged kits? Similar to what can be done with the 4.2s

But whats wrong with V10 Lambo that’s too fast? ;D not a real problem is it?
