If you're trying to flow more than 70 lb/min, and trying to get more than 600whp, unfortunately our stock fuel system will not be able to support it.

Even if we can raise our fuel pressure to 2800psi thru trifecta tune/HPT tune, the stock fuel system, still have a hard time.

Water/Meth kits are nice, and will help cool the air and prevents detonation. If you use 100% pure meth, it will help add more fuel, but it can only do so much even if you add 4 injectors on the manifold. I was talking to Chance from Devil's own, and he advised me that if I really want to add more fuel during high boost/more air...........water/meth spray is not the way to go.

So after consulting with different LNF tuners, I ended up going with PORT INJECTION using a secondary fuel rail. I will also use an additional fuel cell so I don't have to tap from the stock fuel tank line.

This will make sure that I will have enough fuel injection during high boost/more air during high rpms.


I would like to give THANKS to these companies for their support of my compound turbo build:


Ross Machine Racing 410-510-3023 - High Performance Aluminum Fuel Rail and Billet Aluminum Intake Manifolds and Manifold Parts = -8 fuel rail, brackets, and bungs

RC Fuel Injection = set of 70 lb RC engineering injectors

Nitrous Express » Next Generation Nitrous Oxide Systems = SAFE fuel system w/ high output fuel pump and adjustable fuel pressure regulator

Split Second = Additional Injectors Controller and R4 Software
