Mazda RX-7 [FD3S] SakeBomb Methanol Injection Tank

  • Sale
  • Regular price $445.00

Inspired by the "Euro Spec" rear wiper tanks from select international markets, our purpose-built water/alcohol injection tank for the FD3S aims to add a seamless water/meth injection solution to all FD's with the reliability and integrated design as Mazda would have done from the factory. Beginning with a 3D scan of the OEM "Euro" Tank, we went to work to remove unnecessary features, refine the design and test, test, test until we were happy with the final product.

Testing and design work included countless designs revisions, CFD (computational fluid dynamics) modeling, extensive fitment verification, real world testing and the integration of a deep anti-starvation sump to address potential starvation issues for the most rigorous track cars. We've maximized capacity and minimized starvation, so you can use the very last drop of water/meth before refilling. A whopping 2.1 gallons worth! All while hidden beneath the OEM rear plastics with only an OEM-style cap visible. We think the end result was worth the long design hours, and hope you feel the same way when installing this in your FD!

Sakabomb methanal tank

The quality of the tank and thoughtfullness of its design is amazing. The way it fits away out of site, holds more and requires no modifications are the reasons I chose to buy it. I'm not disappointed. I do wish it came with instructions, however I was able to find some online that were a bit confusing. However I don't have the rest of the kit I'll use with it so once I'm do I'm sure it will be self explanatory. Very pleased.
