Hemrick Performance Wet Nitrous System
The difference between a dry nitrous kit and a wet nitrous kit is that the wet kit provides a fuel nozzle along with the nitrous jet to provide the fuel needed for the nitrous added.  After using the prototype for a year, we found that the fuel solenoid could stick closed causing the system to run lean.  We have decided not to put the wet system on the market.  The dry system is a lot more reliable.  The same amount power can be accomplished by using fuel injectors large enough to handle the power increase.

Dyno Results are in!


Non-Nitrous:  87.40 HP / 98 TQ
With Nitrous (.030 jet)  128.88 HP / 147.52 TQ


Our wet system is under development .  We are currently experimenting with the prototype.  One of the problems that we have encountered with nitrous for Harleys is that the power is restricted by the amount of fuel that the injectors can provide.  This problem is solved by increasing the size of the injectors.  The stock 2007 and up 3.89 gms/sec injectors can only provide enough fuel for approx. 100 horse power or less.
 
The reason that we use a Dry Nitrous system is to keep from having to install an external fuel pump with the extra wiring, plumbing and extra nozzles while keep a clean appearence.  Our prototype does not use an external fuel pump and the extra plumbing looks clean.
 
We will offer this system after we have completed dyno testing and product reliability.  Check back soon or e-mail us to be notified about product updates.
 
 
We are also developing a nitrous system for "Non Baggers".
The problem with non bagger systems is hiding the system where it looks clean and neat.
