i was wondering what is a safe amount of nitrous to use on a stock D15B7. and keep in mind it will only be used at my local dragstrip.

 

Wet or Dry?

What type of fuel delivery?

 

sorry it is dry.

 

I'm guessing your using a stock fuel system?

 

yes stock D15B7 but will upgrade to better fuel rail and pressure reg. and injecters before runing the kit.

 

55 jets should be fine.

 

As long as u'r not going to starve the engine from fuel durring using the Dry kit you can run a 75shot on it without hurting anything.. Just make sure that you have it tuned so that there is enough fuel pressure!

 

and what kind of HP gains am i looking to gain with a 55-75 shot?

 

those numbers are the HP roughly at least it is on the ZEX kit

55 shot dry = 50 WHP

 

um..might aswell get Zex if you arent that experienced wth Nitrous systems..reason being,it come swith its own computer for fuel and Nitrous regulation..so you can basicly run it all day with the propper fuel Nitrous ratio! good stuff..good luck..
