GazB Posted May 21, 2008 Share Posted May 21, 2008 What does anybody think of these? Do they work? What does the whole system including fitting cost? What other alternate systems are out there? Reading the info they have on their web site it may be something i'm after, but i woundered if anybody had already gone this path and what is the gain for pounds spent? Are they just another PITA I'm doing a bit of fact finding before i leap into buying if anybody can help it would be much appriciated. Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted May 21, 2008 Share Posted May 21, 2008 Adding water injection is primarily a safeguard rather than an out and out tuning add on, it can be used to run slightly higher AFRs and more aggressive timing, but it takes careful mapping and you need to run some fail safe devices, Aquamist stuff is very good, there are some cheaper systems out there, but i have no experience of them.

tooquicktostop Posted May 21, 2008 Share Posted May 21, 2008 Mark at Phoeinx is fitting this http://www.aquamist.co.uk/phpBB2/viewtopic.php?t=1244&start=0&postdays=0&postorder=asc&highlight=&sid=b3191daaeb64d4990a7e3e91e2c68d4d to my single car, it fits in very nicely where the charcoal canister used to be, I have fitted this as I was getting high EGT's in my old set up, I know this was partly due to TF and Mapping issues but this does bring some piece of mind Link to comment Share on other sites More sharing options...

mikeyb10supra Posted May 21, 2008 Share Posted May 21, 2008 Consider alky control as well - seem like good pumps and I believe if you were bold enough you could run 100% meth if you really wanted Link to comment Share on other sites More sharing options...

Robbie Posted May 21, 2008 Share Posted May 21, 2008 I'm getting a direct port version running 50/50 meth water mix this week. It uses the same stuff as the the one on the aquamist site with a few changes to the fittings. I'll post up some pics when its all in. Link to comment Share on other sites More sharing options...
4packet Posted May 21, 2008 Share Posted May 21, 2008 I'm looking at fitting my aquamist (original pump type) kit soon and interested to know how people fit everything together. Looking at drawing from the std washer bottle; engine bay is relatively std, but have a Greddy FMIC and Apexi induction kit. The concern I have is that the pump doesn't like to suck and the only place I can see to place the pump is between the battery and the wing which is a little high relative to the water supply and limits where the water jet can be placed as this must be higher than the pump also. I have considered utilising the rear wash pump outlet as a means of priming or sustaining the feed. Suggestions gratefully received! Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 21, 2008 Share Posted May 21, 2008 If anyone fancies WI I can do a great price on ERL Aquamist products. Link to comment Share on other sites More sharing options...

Bung it all in the boot, and use a priming pump, the Aquamist pumps don't like high temps under the bonnet, i think there are some pics of my install around somewhere on here, if not on the Aquamist site.

bignum Posted May 21, 2008 Share Posted May 21, 2008 You will defo notice a difference in hot weather even on a standardish car, pulls much cleanly to the redline and the added peice of mind of some sort of knock suppression. Link to comment Share on other sites More sharing options...
Swampy442 Posted April 17, 2010 Share Posted April 17, 2010 Bumping another old thread Im getting a car that has water injection fitted, and from research it looks like Ill be keeping it. So, how do those who have water/meth control it and where do you get your meth from? Do you use demineralised water? TIA Link to comment Share on other sites More sharing options...
JamieP Posted April 17, 2010 Share Posted April 17, 2010 You can get the methanol from most RC model shops, i dont bother with it anymore tbh, with a good map i dont see much point in it, never made any difference to my intake temps. Link to comment Share on other sites More sharing options...
Terminator Posted April 17, 2010 Share Posted April 17, 2010 I though water vapour is more dense than air, so with just in the tank water you get more oxygen in the burn, so an aid to combustion. Add Methanol and you get more power and less likelihood of det as the overall octane number goes up. Don't forget it it was used in production cars and in F1 but got banned because it gave cars too much power. Link to comment Share on other sites More sharing options...

TIA Aquamist do a programmable WI ECU, or if you have a piggyback such as EMU you can use that, or the simple solution is to just use a manifold pressure trigged system. DON'T use model shop methanol unless you first check to see if it has an oil content (which most do) unless you specif otherwise, or you will. be defeating the whole object, as adding oil can actually lead to detonation.

Don't forget it it was used in production cars and in F1 but got banned because it gave cars too much power. Most WI mixes don't recommend more than 50/50 so any gains are marginal, it will aid lower in cylinder combustion temps which as you say will lead to improved efficiency and less chance of det, WI is still used on some production cars, i think Noble do, or at least the export cars. The reason it was banned in F1 is down to with the right tec and control it will allow much more aggressive IGN timing and leaner burn, so more power, but everybody would need the same setup for it to be legit, it won't produce more power on its own, having said that i have heard of it being now used with the modern diesel cars to very good effect;) Link to comment Share on other sites More sharing options...

Terminator Posted April 18, 2010 Share Posted April 18, 2010 Some forced induction engines with WI running a water and methanol mix have run very high compression and boost, with out an intercooler, it is that effective. Link to comment Share on other sites More sharing options...
