[want to boost]

Hello everbody.

I was wondering if there are any people who are using nitros and water injection. I am currently running water injectionm and will be looking at running nitros in the near future, anybody got expierence with this?

Thanks

Yea, the 2 can be ran safely together. You will want to tune for the Water injection first and then tune for the nitrous oxide.

I just found this forum, I've been using nitrous for years and am now thinking about adding water injection to my 540.
Tons of posts here to read, I'm sure I'll be back with more questions.
I'm running a NOS dual stage setup (NOS Progressive Controller) with a heated 20 LB tank, 1st stage is 100HP the second is 50HP.

They work very well together, I use to run around 70% methanol with my nitrous set up, Dropped .3 seconds off my times vs nitrous/race gas. Blew up my diff but it was still worth hitting 11's.

I thought methanol and an aluminum engine don't go good together??
I changed my diff to the M5 posi unit, I shouldn't blow that one up.
I'm at 450 HP and 540 ft lbs now, but the car is heavy...3700+ lbs.

The way alcohol injection works it is fully vaporized, That is one of those old misconceptions, Aluminum will have issues with immersion in methanol, Alcohol injection is not immersion. Methanols low evap temp ensures it cannot stay in liquid form when it is atomized properly.

OK, so here is what I want to do with the 3 cars I own.
S60 Volvo and V70 Volvo, both non-turbo, 2.4 liter 168 HP, 5 cyl engine.
Install the kit in each car for some amount of time just the steam clean the tops of the pistons, steam is a great carbon cleaner. In the old days we would trickle water into the top of the carb with the engine at a ~3000 RPM.
So what size nozzle would you suggest for this, and how long do you think it will take to clean the pistons? Both cars have about 85K on them with most of it being highway miles.

Then the 540 Bimmer, 4.4 liter V-8, 300 HP non-turbo 109K miles. I want to clean the carbon off the pistons too, so I'm asking the same as above, how much flow and for how long?
After that I want to up the water/alcohol flow to use it with the nitrous (additional 150HP with nitrous) that I have on the engine.
What should the flow be set to?
I know that I will have to control the pump differently, as there is no boost to activate the pressure switch. That shouldn't be a problem, I'm an electrical/electronics guy.
Can these pumps be operated with a PWM speed controller for ramping the flow up as the RPM increases?
Sorry for all the questions.
Thanks in advance.

We already sell a Progressive Controller that uses PWM for the kits. You can simply install the Universal Stage kit with the voltage faced controller on your vehicles. On the Volvo's you only need a D01 nozzle to get the steam cleaning and lower intake temps. You will however get better throttle response and lower overall engine operating temps.

For the 540 a DO2 nozzle would be all that you would need. And if your running it with nitrous run 80% methanol. (Huge kick in the butt)

You can activate the kit from your stock MAP sensor, MAF sensor (recommended) or TPS sensor.

Thanks for the quick reply.
I thought methanol wasn't good to run in an all aluminum engine. Would a 80% alcohol mix give just as big a kick?

[dvldoc]

There are many all aluminum motors, like in cart racing that run pure methanol as fuel, The only way for it to effect aluminum is if you soaked your motor in a vat of methanol.

Yes 80% would give you around the same, plus a little bit more cooling from the water. I played with all mixes when I ran it on my GTP.
