Water methanol injection is the way forward for 1.8t tuning
« on: 09 June 2011, 19:07 »

Anyone else using it?
The gains are awesome and cheap to run just on de- ironised water.  No one actually writing a map for water injection for the 1.8t me7.5 so se set to work on it today. The water injection allowed to run much more ignition advance across the whole rpm range and to run much leaner fuel air ratio mix and still be safe.  Plus the option of running on happy shopper 95ron fuel and get the same results as v-power or even 102 race fuel when added with meths.  I will be posting the results up next week after a bit of play time. With the same setup we managed 508bhp from an astra turbo at 1.7bar 13.2:1 fuel 26 advance.

Hi mate, nice to see you on here :-)

I've got a DevilsOwn Kit, which i had fitted to the diesel, and gave me some GREAT results!

What kind of extra power do you think we could see on the 1.8t?

Hi I bought a aquamist water meth injection to use on my build but was just wondering where the best place to inject it in. Is it best just after the intercooler in the pipe or have read that it can be injected straight in to the inlet manifold. Can it be done on a standard manifold or do you have to use one of the high flow jobies?

a few of the diesel guys run it on uk-mkiv's as i was looking when i had my Leon.. they reported no differences at all and promptly removed.. maybe this is different on the petrols.. i know a lot of high horsepower cars love them.. but how much would ti cost to keep it topped up ??

Like RTechUK said you can just run it on water dont have to use meth all the time so shouldnt be very expensive to run, I guess the gains would be better with meth mix tho. Im aiming for around the 350bhp mark so hopefully it will mark alot of difference!

It does and other stuff so putting that through your engine may not be great. Im gonna use my screen wash bottle so a mix of water/meth in there will clean my screen as well!
