So, I've done what I believe to be my due diligence serching through old nitrous posts, and most of them were just that...old. I saw things referencing the power commander 3 with the multi-function hub, and older things.

So where I'm at is this. I'm looking to add a little extra power to my 2011 zx10 and I looked at boosting it but that was going to be a nightmare. a friend has an old k03 turbo off his Audi that would have worked but there are no kits out there for this bike that I can find, so nitrous it is.

So, in order to get the extra horsepower, I'm thinking of the "dry done right" nitrous kit from nitrous express. my questions are these.

• does anyone have any experience with nitrous on gen 4s and care to add any thoughts?
• should Christ moore be able to tune a nitrous map into one of my power modes, or do I need a power commander?
• Is there anything that I should add that doesn't come with the kit? (https://store.schnitzracing.com/nx-four-cylinder-motorcycle-ddr-nitrous-system/)

Thanks if you made it this far. Any advice is welcomed

How big of a shot, and what fuel are you willing to run?

Well, I wanted to run a 40 shot, but the DDR kit from nitrous express has a 25 and a 50 nozzle so, I gotta pick one. can I run the 50 on stock fueling?

The actual shot HP/TQ will depend on how it is delivered (spray bar, fan nozzle, bottle pressure, etc). 50 is a lot for a stock motor bike, but I've done it on gen 5 without issue.

Pump fuel? On a 25 shot, sure. On a 50 shot? Playing with fire. A good VP fuel is a lot cheaper than motor repair, and a lot less aggravating. Honestly, you should have this conversation with whoever is going to tune the bike, as they will have a preference/plan for how to make it work for them.

As far as kit extras go; I wouldn't use that set-up myself. Trying to set-up a mechanical TPS switch is going to be challenging, and a 50 shot in all at once in 1st gear might be reeeeally entertaining. A good progressive controller will have a WOT switch/window switch function, and allow you to ramp the hit in.

Okay, this is all really helpful. So, it sounds like 25 is the shot to go for then. my plan was to only use the nitrous in 3rd gear and beyond, I can't WOT in 1st or 2nd gear anyways without it standing up.

Are you saying that you wouldn't buy this kit at all? It does come with a WOT switch, so could I just add a progressive controller to the kit and be good to go?

Also, I'm willing to run E85. I would love to not have to upgrade injectors or fuel pump though, so IDK if they are sufficient to handle that.

That WOT switch will be challenging to configure correctly; a progressive controller will have the WOT switch built in, and also a 'window switch'. A window switch allows you to set an on & off rpm... helps to prevent early activation and/or bumping into the limiter while spraying.

E85 will work, though it isn't an ideal fuel for nitrous. A 25 shot can be run on pump gas, all day long, probably with no/very little change to timing.

...and to be honest with you, a 25 shot sprayed only in 3rd gear and up isn't going to do much to make it faster. It will have little to no impact on ET, and a mild effect on trap speed. If you want to put distance on someone in a race, it needs to be on the first time the bike sees 90% throttle or better.

As far as that 'kit' goes? eh, I'm not a huge fan. If you don't mind doing all the work to make it fit (bending lines, finding places to put shit, etc), it's not a bad way to save a little money.... but I'd prefer a spraybar set-up with at least a progressive controller if it was going to go on any of my bikes.
