A good water/meth injection system set up to supplement your good tune on your fuel of choice to be an added safety buffer and keep your AIT cooler is a great option. At 13:1 compression you probably only need to run 8-9psi to net 350whp anyway. How good and engaged your tuner is in knowing/finsing where your detonation window is be the most important thing, so choose one wisely, one that's familiar with boosted S2000's.

But id keep the current HG in place.

Thanks guys...I was looking into meth too but it seems like if you're running e85, meth is kind of not necessary. But I'm sure both wouldn't hurt lol
Wonder if anyone has run both?

Both will put a lot higher demands on your ignition capability with being such low volatile/combusting fuels. I'm sure both used together can be done, but it probably isn't needed, nor is it very efficient, especially if your keeping boost at pretty moderate levels. What water/meth will do for you is allow you to get like E85 detonation suppressant wile running pump gas. If you have E85 available in your state then its all you need. That's not always possible for some. We don't have E85 available enough to rely on in my state.

Have you run meth? Any info will help.
Ive read the main issue with that is the cylinders do not get equal distribution with one nozzle on meth. I think Id rather run meth as I currently use 100 octane which is very easy to get for me and e85 is not available at the track. If I can do meth and have one gallon last a day Id be good with that.

Yes ive run it.

With a typical single injector pre TB set up its true that there will be some unequal distribution between each cylinder, and for that reason its why that type of configuration should not be relied upon heavily as a power maker, but rather a way to keep IAT in check/lower and get some of the residual effects of added safety from detonation suppressant. For squeezing out max performance with high boost and aggressive timing taking place of a race fuel, only multi point injection configuration should be used so you have an injector in each runner of the manifold for equal distribution. Ive run it both ways. Both are effective, but for different reasons/duty desired.

If you do a search of some older water/meth threads on S2ki you will see me chime in and get more in depth on explaining. Id recommend you start there if your interested in doing this.

Cool thanks! Ill check it out. I dont want to run meth or e85 to make max power but to prevent detonation and keep things cooler. 400whp max is what Id do. 350 is ideal.
Thanks again!
