300HP MULTI-STAGE KIT - SIDEWINDER and SRX

This powerful kit will gain up to 100 horsepower over stock and still run on 91-93 OCTANE!!! And its fully adjustable on the dash!  Get your Sidewinder or SRX tuned up to the Max!  Just send us your ecu and speedo gauge for a quick Hurricane reflash for both, and then install our awesome stainless steel muffler, aluminum charge tubes, turbosmart valve, 3 bar map sensor, and our SSI clutch kit. 

This kit comes with 3 Hurricane Power Tunes:  240HP 87 octane, 270HP 91 octane, and 300HP 93 octane

The new ECU flash is the Super Spool version with has amazingly quick throttle response. 

You can switch power levels right on the dash gauge.  Or you can opt to use the flash communicator and change power levels using Blue Tooth on your phone. 

If you are drag racing, Launch control is another option that can be added which utilizes an adjustable software program right in your phone.  It also also comes with a handlebar mounted switch.  (flash communicator required and part of this upgrade, but not the dash cluster flash)

The muffler is very trail friendly and fits excellent.  Its all stainless steel and polished, and even comes with a new flange gasket.  It is also about 6-7 lbs lighter than the stock muffler. 

Our aluminum charge tube kits dissipates heat much better than the oem rubber charge tubes do. Less heat means more horsepower!!  They won't balloon under higher boost levels either.  The strong stainless steel clamps prevent the tubes from coming off under higher boost levels as well.

The stock Diverter Valve is designed to bleed boost around 17 lbs. The Turbosmart Diverter Valve cures this allowing better power with the high HP flashes.  This is recommended whenever doing our 270 horsepower and higher ecu power flashes.  

The cold air intake fits under the hood for increased airflow and horsepower.  The motor will get a direct shot of cold air right from the intake vent.

Put the power to the ground with our Pro-Shift Clutch kit.  The custom cut helix makes the acceleration pull hard, and our Pro-Mag weights harness the extra power of the powerful tune. 

These kits are very powerful and very reliable.   Just send us your ecu and speedo for the Hurricane Performance tune, which we do right here.  Send it to:  Black Diamond / Speed Shop Inc., 6238 318th Street Way, Cannon Falls, MN 55009.  We can usually flash it and ship it back the same day!! 

Or if you go with the Flash Communicator, do yo don't need to send in your ecu, we can simply ship you all of the parts and you can flash the ECU yourself
