Hi Everyone,
As most of you know, we've been in production of the supercharger kit components for the last 6 weeks or so. The original intent was to add about 100 hp at the crank with a low boost system. The prototype worked well and everyone responded favorably when we began taking names to get on the production list.
Enough people were interested that we had to change the way the kit was built. Simply put, the one off style of the prototype was too hard to reproduce cost efficiently in any volume, in addition to quality control issues associated with so much welding. So, we redesigned the entire kit, with the intent of making it easier to produce. But, while you're there, why not bump up the efficiency and output a bit?
Well, we did just that. Instead of a fabricated sheet metal intake, we designed an intake machined out of a solid block of billet aluminum, with a better designed plenum, cleaner radius into the runners, tighter tolerances on the surfaces, etc. If you're going to make the manifold breathe better, you're going to have to increase the air inlets to the supercharger (dual 3") and put on larger aftermarket throttle bodies (70mm polished). Well then we're going to need to use 3" smooth tube and of course buy stock airboxes and modify the outlets to 3". That should do it, and it did. The result was a better kit that ended up making more power. Instead of making 100 more engine HP, we made....., well, I'll just show you....
The compressor and pulley were the same as the prototype, running at 5.5 psi now (the increase in inlet and throttle body size reduced the vacuum at the intake of the compressor and allowed it to make more boost).
Here's a picture of the kit on our GTS. Most all of the components are the actual sample production parts. The hoses are not the actual parts as the real ones are being made in red silicone and are still a few weeks out. Unfortunately, we're still perhaps 8 weeks out on having everything here, polished, anodized, painted and fitted. That's what I get for not leaving well enough alone.
As an FYI, the dyno test was with 1&5/8" primary tube headers, high flow cats, etc. as shown on the dyno record. We will install 1&3/4" B&B headers, no cats and 1.7 ratio rockers in steps over the next few weeks while the production parts continue to be built. We expect to make more power with the additional upgrades.
Thanks for reading,
Sean
