Water/ Methanol Injection

[atessa]

been talking to a few lads (names hidden to protect the dodgy) about water/methanol injection systems.

the boys are saying that a good injection system (couple of injectors into plenum) will lower intake temps more efficiently than spending $$$ on bigger intercoolers. given our usual climate is 15 - 35 degrees - it kinda makes sense. yet i see very little about this on the net.

costs are about the same as a decent intercooler. ie good quality pump, couple of good injectors, thermo sensor to trigger injection, and water/methanol storage bottle. - less than $1000 and the word is more effective in our climate.

any thoughts?

particularly re the effects of water and/or methanol in the engine - supposed to be small doses, but could imagine a malfunction dumping too much could be ugly.

he made a kit for his 32 gtr, and has a digital temp readout in his dash, apparently drops the temps quite well!

In a volvo turbo, the temp of the air after the turbo was dropped by a cool 15 degs after adding the water injection kit(i think it dropped from 65 to 50 degrees? If i remember correctly). And in a climate like Singapore, where it's purpetually 33degs avg in the day. It's substantial.. you can really feel the extra oomph.

When u buy a kit, make sure the kit has a solenoid (normally closed solenoid) to prevent leaking, cause the cheaper more dodgy kits uses the pump to control flow. This is very very impt!!! Esp if u're doing direct injection to the manifold and not after the intercooler.

A better kit has a boost sensor built in and u can set the injection to activate when you're in boost. A good kit allows variable injection rate that can be mapped to ur rpm, and engine load.

Had a friend who bought a dodgy kit, left his engine dead. That should say a lot. Prepare to pay about $600 usd for a good kit. Well.. kinda top of the line kit.

Cheers!
