I want to build a nitrous motor
« on: April 08, 2004, 04:07:45 PM »
Where do I start?  It's an '02 GSXR 1000, which currently is running a 60 shot thanks to A&J Performance.  I want to step up to a 100 shot.  I know I will need rods, valve springs, lockup, & billet basket,  but I don't know what compression to go with.  MSP recommended 13:1, but this has to be a motor I can idle in traffic with and not overheat.  Any suggestions?

Nitrous works find on stock compression the lower the comp. the more you can spray.

The higher the compression, the less you have to spray.

Thanks guys, but you haven't gotten me any farther than I already am.  I'm looking for what other people have done, or suggestions.  Pros and cons.  Has anyone seen a 100 shot on a gixxer?  Can they give me some details?

bottlefed I ran an extra 80hp ( wet system) on a bog stock bussa motor for a total of 60 sec , I  ran at least 12 runs ( not all at 80 shot or 60 sec but all between 40/80 shot and a min of 15 sec )   without any retard  also the secondary fuel was 100% toluene , only problem I had was #1 spark plug  earth strap melted ( NGK iridium  ) I will not use these again  changed to NGK racing plugs  no further probs I have now striped down the motor and its like new no visable damage at all  hope this is of use

im currently working on my 01 1000 that i just picked up. i have a wet system on my busa. i told joe(A&Js) i would use the dry system and controller that he offers on mu next personal bike.. pm me or give me a call. # is in my signature. i can get you to a 100 shot.  you cannot compare a 100 shot on a busa motor to your motor. i live at the track and there has been several gxrs motors coming apart with 60 shots.  i love the spray

A good set of rods, lower comp. pistons , the lower the comp. the more you can shoot.
as far as the clutch goes...thats a whole other can of worms.
As far as stepping it up, you can still use my box, you just have to increase the fuel pressure, by either getting a different pump and reg, and or a better set of injectors, both of which we have.
