Best WMI Nozzle Location for 1.8Ts
« on: 20 September 2012, 17:13 »
Hello Guys,

I'm looking for best nozzle location for 1.8T engines. Some users using TB plate for injection some users using post intercooler location for that.

What's the benefits this locations ? Could you please compare them ?

Thank you !!

I do not know which is best, but I believe people say giving putting in post and close to the IC gives it maximum time to mix  :smiley:

Weather or not you'd notice a difference if you put on the TB or close to the IC is debatable and perhaps one for some tuner to try out/some one give me a link to a thread  :grin:

After discussing with fellow meth users we figured its best located after the intercooler in the hard pipe before the tb to allow maximum cooling time of the charge  :wink:

closer the inlet the better.

if thats the case then why does nick(rtech) use direct port nozzles?

Use the port on top of the throttle body?

WMI is a vapourised mist anyhow.

Doin it direct into the manifold gives the most cooling as it shoots large droplets of water/meth straight down into the engine but for this you need multiport injection
For single nozzle you want to put it straight after the intercooler to allow maximum time for it to mix and also before the sensor.

yup, two different types of benefit from the WMI.

Injecting early gives the biggest cooling benefit as the mixture has time to atomise and cool the charge.

Injecting late into the inlet manifold works better with higher concentrations of meth as you're mainly using the octane benefit of the meth.

Both have similar results in that more timing can be added. On a road or track car I'd go for single port injection just post IC. On a car used for drag racing I'd go with direct into each inlet runner.

I plumbed mine in like this:

Hello Prawny,

Can you please share your setup ? also do you have a ignition timing logs and IAT logs ? if you can share i'll be happy.

i'm thinking post IC location but too much tuners using TB plate location.

Also, I need more octane level and lower IAT. this position better than..

Direct injection very fantastic job but all nozzles will come to IAT sensor. How can you solve this issue ? timing will be calculated incorrectly.
