just water

[smokinHawk]

i was wondering on how much more boost you can use with just water, for certain racing classes that dont allow meth or alki injection, but allows water injections
what type of gains do you guys see with just water?

Water allows additional boost, but not a lot. I would say 20 % more boost. Your knock sensor wont lie.

Plus how do they know its not alcohol.. they both look the same.

I'd hide an alky tank under the fender

Those things you cant compete against displacement.

id like to run meth most of the time, but it would be race classes where they are very strict and would do testing to verify it, aka hot rod pump gas drags.

can your kits do water well? im sure the pump can take it but do the nossles mist it ok?

 

[Razor]

If I had to do water, i'd go with the aquamist nozzles.

Sad those competitions favor larger cubic inch motors.

sounds like i would have to switch nozzles then.

do you think water could give me an extra 50 horses?

Only if you add boost. Spraying water does not create power. It allows higher cylinder pressures to be run and not detonate. So yes you should be able to get another 50 ponies. Dropping the nozzle size creates a much finer mist, fine mist is needed for atomization to occur. And you dont try to get tooo aggressive with water.

This is where alcohol differs.. shooting straight alcohol not changing boost.. the motor will pickup RWHP cuase it burns. And one can run way coarser nozzles and really pump the liquid in.

Two ways to skin a cat. The tuneup is way different from one realm to the other.

So would it be ideal on all apps to run multiple smaller nozzles, like 2 m10's or even smaller instead of one m15 due to it being a finer mist?

Do you mind if I ask a general question that doesn't really pertain to the thread??

theoretically, how many ponies can you get from a car that runs 20 PSI on pump gas with a basically stock intercooler (dutt neck) and a PT-61.

I know with alky (and of course the right tune) I can get around 27 PSI (which is what I plan on running)...and I was just curious (I know you can't give me an exact) about how much HP you think is feasable conservatively.

No, i'd be using 5's or smaller and doing multiples. Like 3-4. You really need to get the atomization. Look into the aquamist nozzles. Like the M1 and run a bunch of them.

You dont want a coarse spray pattern. Its a different world than alcohol.

50 horse, sure.

There are way more variables like condition of motor, head work, cam, exhuast, timing, and how much tuning is employed. Stock they were like 250. Add 5 PSI, should be about 300? The 61 is not in its range at that power level. Probably be faster with a stock turbo at this boost if the rest of the motor is stock.

At 27 PSI the 61 will shine.

 

[Slow91z]

Motor is stock except for the Valve Springs, exhaust is 3" all the way out, 18* of timing.

you could also run a bigger turbo (70 size). with good heads, cam, stock location intercooler, and converter you could look stock and still be fast on pump gas cuz your running less boost ut makin the same power. i saw a guy a while back running ported iron, t-70 and a cam or something and did 11.0 on 93 oct. of course on slicks but im sure if you used like some MT E/T drag radials you could get mid 11s.
