talking of drilling and tapping into compressor wheel housing, my mate came up with a good idea today.
using small compresser bottle in the back of the car with 12v pump, run a air line to a solonoid wired up to throttle position sensor so when throtle open - solonoid open conected to a jet tapped into compressor housing to spin the turbine as soon as throtle opens.
we were ****ing about at dinner today blowing air line into a goosed t3, instant spool i must say!
could it work and take some lag out??

Not sure in what measurements your nozzles are rated but mine\'s 5GPH, for 400hp.

asp

so what ur saying is car 1 with 400hp and car 2 with different spec but still with 400hp,both cars need different size nozzles?

sory i thought u had 350 hp which I would say you need around 3.8 gph of water. This will depend on the air temp. The lower the air temp the less likely the water will be to atomise correctly. You will still need to advacnce timing or remove fuel to counter act tho

pip told me rotarys take water well, (its surprising how much u can chuck in) is words where

Trust me with water i quote "little is more"
If it were methanol you would require a lot more

Asp you want to be aiming for about 18/20% water to fuel ratio if you can. that why you need a hp goal then you can work out the amount of fueling to achieve this and from that the amount of water required. Don\'t know what kit your thinking of fitting but certainly cooling mist will select the most appropriate nozzle size if you tell them engine type and estimated hp range.

this is a little more tricky than i thought,every thing on the engine is new, still running the engine in,all i know so far is i had 13 air temp on comander but that was in the night,

140psi Shurflo. Try Williamson as a dealer and they should have one.

I don\'t think so but if you check out http://www.shurflo-original.com/  for a phone number, give them a call and ask for williamson\'s phone number, and ask them to send you a free catalogue (huge) while you\'re at it. I\'d give you the number now but I can\'t find it again. Wav may know since i sent him the number the other day.

Edit : They also sell shurflo pump parts seperately so you can rebuild them, or change the upper housing to different hose fittings.

hp goal not to sure yet,iv got a coolingmist kit,i didnt tel him what hp i had so i got sent a 3.9,
so what i should do is talk to the person whos goin to tune the car ask them what sort of hp i might get,then look at getting the corect nozzle size,
cheers for your help guys :)  :)

This is taken from cooling mists website to give you a idea of the injector sizes available Kriss you may well find your about right with the nozzle size
QuoteChoose the flow that you like listed in Gallons per hour in the drop down box, the flow is rated at 150 PSI , they will have a lower rating at 100 and 60 psi. high quality 1/8th brass NPT style fitting. Our single stage water injection kits come with 1 nozzle. Our Dual stage come with 2. Order one of these if you would like additional nozzles for tuning or you can order these without having to order a kit. At 100 psi the translation is as follows:
.75 @ 150 =.50 @ 100
1.3 @ 150 = 1.0 @ 100
2.8 @ 150 = 2.3 @ 100
3.9 @ 150 = 3.0 @ 100
6.0 @ 150 = 4.9 @ 100
12 @ 150 = 10. @ 100
18 @ 150 = 18 @ 100

For a quick twin turbo 3.9 should be fine and certainly make a difference :)
