Anyone here running a Water/Alcohol sprayer with a high compression built NA motor? I read that some people think it's only for FI setups, but it seems like it'd be perfect for the guys running high compression on street fuel so they don't have to constantly run race gas.

Why E85 could be a popular acceleration only fuel with just an extra row of small injectors coming in when ever you need a mixture richer than 14.7.
In theory less expensive than pump gasoline but 100+ octane, you would need 50% more E85 flow than the standard gasoline flow [what creates 14.7 AF] to get 12:1 AF for acceleration.

Well it just makes sense to me that an Alcohol/Water Injection kit would be helpful on a high compression NA motor. I can't remember who makes the kit I saw for the 350z and I can't even find the kit online atm! but I know they exsist. Has anyone tried this yet? Seems like a good way to use 91/93 octane and run a high compression without worrying to much.

Plenty of people use meth injection. I wouldn't emagine too many NA guys do, but it wouldn't hurt. Also, injection kits are for the most part, universal. I took my meth kit off of my Evo and installed it in my 350 about a year ago. Don't have it anymore, but they're a dime a dozen over on the Evo boards.

Do all the bolt ons first after I get a handle on the car, then start building up the motor from there. I was thinking since the alcohol/water sprayer(injection) is supposed to simulate higher octane I thought it might help with high compression with 91 **** gas.

its primarily a cooling agent - it's not going to net a huge difference on an NA car unless you run massive compression, at which point you mind as well just inject alcohol or nitromethane and really make some power ![Smilie](https://my350z.com/forum/images/smilies/smile.gif)
not what you would want to run on a daily driver (at least you dont want to inject meth or alcohol daily) but water would be perfectly safe

safer? If the motor is tuned to run on 91, it will run great on 91, and won't run any better on 93, 94 or 100. It's all in the ecu tuning. It is my experience that modern cars, with coil on plug ignitions, would not see any benefit from water injection on an NA setup - on forced induction, its an awesome tuning tool
