Default I did mine via the intensive washer tank, but actually reversed things...

..since the intensive washer tank was smaller, I hooked up the windshield and headlight washer lines to that tank, then just bought a new primary washer tank with filter, and ran the water injection lines to that. You do NOT want to run out of water on the track....it can kill the pump if it's not protected from running dry, plus people will pass you.

I'd pour straight blue washer fluid into both tanks, and the car would run like an animal at the track. I could detect no difference between 100 or 104 octane race gas vs. 89/91/93 pump gas plus water injection. In fact, 89 plus WI felt just as fast as 93 plus WI, and there was a noticable loss in power the few times I did run out of washer fluid in the tank (and I cooked my pump once because of it).

Blue washer fluid is 50/05 methanol and water in most cases, and methanol is 114 octane or something crazy-high like that. Don't use orange or the anti-freezing formula.

Default Thanks Bruce.......I'm surprised more people aren't using water injection in these cars.....

for the money it's probably the most power you'll get outside of a chip. Can't wait to try a dyno run w/ and w/o.

Default Not sure why either; loved it! But I see it as keeping all your HP from getting robbed....

....by heat soak, not actually making more HP.

Agreed, that and my FMIC should keep things in order in August heat.

Default because you don't gain that much power unless you can actually tune for it. and then running out of

water becomes a much bigger problem than burning the pump. have you tried using 100 oct, it's not THAT different if you chip is designed for 91/93.

it will basically give you high octane gas for a cheaper price and steam clean your engine, but unless you tune for higher octane you won't see tremndous power increase.

Exactly right..and if you tune for it, you better have great knock protection or don't run out!

Default well the pump can also fail or get clogged too. i like the idea of using it as a safeguard

but not relying on it for power. maybe if the AAN wasn't so expensive, i'd be willing to use it.

Default Has anyone used the low washer fluid warning to disable the injection pump?...

I'm not sure where it is or how easy it would be to tap into, but if the low washer fluid warning was part of the water/methanol injection pump power circuit, you'd both get a visible warning when you were running low on fluid and prevent the pump from burning out.
