Smile Vishnu N55 Large Chargepipe

Hi guys,
Here's our prototype n55 chargepipe. It's massive at 3.25" OD. Fits perfectly and doesn't budge once installed. No welds and a constant radius bend entering the throttle body. The 2.5-to-3.25" transition occurs smoothly in the silicone elbow, not abruptly in the pipe or at the throttle body. The idea here was to keep turbulence and charge velocity at the minimum conceivable levels. Not only does this minimize pressure loss, it also improves methanol atomization and distribution. The thick wall aluminum pipe also allows the Aquamist nozzle adapters to be screwed directly into the pipe which means no additional bung welds.

Installed:


Installed:


Comparo stock vs. Riss Racing vs. Vishnu Large Chargepipe (n54 version)


Raw unfinished material:


We will have prices and availability shortly

Shiv

We should have them ready for sale the week after next. They will all be powercoated black unless anyone prefers unfinished aluminum like me. I prefer that myself but I'm weird that way.

The intake manifold design is actually pretty darn good. Smooth transmissions, good sized runners, decent plenum volume. Plastic is good since it doesn't conduct heat. And it's also light!

This will look nice with the new aquamist system running into it cannot wait. Put me down for some beta testing on the N54 Shiv! I'll just pick it up from Roberto.

Are you going to be offering an N54 pipe with a BOV instead of DVs?
