Does the standard engine cowl fit? 2018-04-16T06:45:54+00:00

Yes the cowl remains 100 % untouched; we do add a 114 mm (4.25 inch approx) spacer that is attached to the standard cowls internal latch points, the standard latches are then bolted to the spacer. Then the cowl simply goes on in the standard manner.

Cowl Graphics 2018-04-16T06:46:40+00:00

The production cowl graphics and sticker kit have yet to be finalized. The graphics applied to the pre-production kit are to clearly display that the engine is running the 450s supercharger package.

Which Yamaha model does the Nizpro Supercharger kit fit? 2018-04-16T06:47:34+00:00

Our Supercharger kit fits all F series 225, 250 and 300 V6 4.2 liter models. It also fits all 200, 225 and 250 SHO V6 4.2 liter Models

Is reliability and durability compromised by adding a supercharger to a naturally aspirated engine? 2018-04-16T06:48:39+00:00

Firstly let me say that the 4.2 Yamaha V6 is an amazingly well engineered product. Any owner of one can be assured just how good these engines really are and how under stressed they are in standard form. In its highest production level { 300 HP } it’s making a mere 71 hp per liter at a lazy 6000 rpm maximum engine speed limit..The standard 4.2l V6 Yamaha is engineered as standard with high quality connecting rods, oil cooled pistons and a compression ratio that is low enough to suit forced induction. So it is a brilliant platform for forced induction.

We started this project in 2013 and to accelerate our own durability testing program we are running our pre-production tests at well beyond the 450hp power level, Higher rpm with substantially higher boost pressures than what the production 450hp package will be released with. Up to date we have seen zero failures of any kind using a standard Yamaha 4.2 V6 engine.

Lower Unit strength 2018-04-16T06:49:24+00:00

Currently we have seen zero lower unit gear failures. We certainly understand that at some point the lower unit will become an issue and are already taking steps to be able to offer upgrades such as prop shafts, gear sets, input shafts and nose cones.

Production and manufacturing 2018-04-16T06:50:09+00:00
