Water meth has been in for a while now (few months)

Running the USRT throttle body plate/adapter, so its post throttle body
I am only currently running water and it makes a huge difference. On a warm day it looses the sluggish feeling the car used to have.
Looking forward to adding some more nozzles and playing with timing etc soon

Oh its a Snow stage 2 kit, with optional solenoid, AEM filter and level sensor, with the bigger tank and USRT throttle adapter plate

Here are a few pics

Still molesting this poor car :p

Nice work as usual!

The molesting is just starting Pierre

Do you have any pics of the post throttle body plate/nozzle mount? When you run water only through the post throttle body nozzle, whats the water consumption?

[vwthunder]

Dont have a exact pic, but here you go VW/TT 1.8T & 2.0l 8v Dual Nozzle Mount Package VW/TT 1.8T & 2.0l 8v Dual Nozzle Mount Package [SPDPACK] - $110.00 : USRT, Usually Sideways Rally Team

Water consumption, well it uses quite a bit at the moment, depends what nozzle size your using, guess i am lucky i have a big tank.

I have quite a few nozzles here, i should check which one i put in

You'd have to be able to run much more advance with the pre throttle body nozzle wouldn't you? With post throttle body nozzles the inlet air temp sensor won't even see the temperature drop in the manifold will it? Anyone know why they they don't recommend pre throttle body water injection for drive by wire systems. Whats the potential drama?

There's a chance the water will enter the electronics in the TB.

Ok. so if you did run pre throttle body injection it sounds like you'd have to guarantee that all the droplets are evaporated before the throttle body - I guess the short run from the stock SMIC to the throttle body wouldn't be enough for that. Is there such a thing as pre-intercooler injection? The temps would be higher and the pipe runs longer and flatter so there'd be more likelihood of getting all the droplets evaporated. Then the intercooler could do its thing a little easier and the IAT sensor would see the change that the water injection made and adjust mixtures/timing for the better.

I dont know about pre cooler spraying.
Maybe by the time the air reaches the throttle body it has already cooled off. Seems to be pretty simple just about everyone does a post throttle body (thats why they make all the adapter plates) and post intercooler.

You could always try this, looks interesting BigUPPER K03 : USRT, Usually Sideways Rally Team

URST asked me to buy one but i declined

Hoyhoy.

I have a post & pre intercooler nozzle.
Plus direct port nozzles.
