Default Water/meth injection on an N/A

I read through the FAQ but didn't read if water/methonal injection could be done on a non-turbo impreza?

If possible, would it be reasonable to assume a similar HP increase stated in the FAQ (i.e. 20-30whp)?

- Because if this is possible then this could be the best bang for the buck I have seen. Seems to good to be true.

The results of injection depends a lot on the car, the fuel, and the injection being used. The nice thing about turbo'd cars is that the boost can be raised. This along with the fact that turbo subarus naturally run rich makes it so injection on turbo subarus shows great results. I don't know how great the results would be if all you could do is lean out an a/f ratio that starts at 12 to 1, and advance timing. Ie-Some engines probably need more then a tune and a little water to get good results, and they might even end up losing power with injection.

peace

Like he said, N/A cars run at a high AFR anyway, kind of negating the increase in AFR seen on turbo cars when using this injection. Also the water/methanol injection cools heated turbo air also not a problem in N/A cars. My best guess would be an increase in octane rating if using 93 octane and 100% methanol and the increase would not be as significant as in forced induction.

You could probably, my guess anyawy, use it and gain about 15 ish HP. I think there it could be used however in as a supporting mod for other mods. Like you could probably run 12.5:1 or 13:1 compression pistons in the RS block and not detonate and on pump gas. It would require a tune however. All in all would be pretty costly.

cheers

You will be very lucky if you gain 1 HP on a n/a car. We do offer N/A Controller kits, but they are typically designed for vehicles that want to eliminate race gas or want to advance timing past what the stock fuel system can handle. Well built n/a race cars and cars built with very high compression make good canditates. I would certainly look into something different in your situation. Its not likely do do much.
