what kind of performance increases did you notice? which setup do you have?

 

well its about time someone else asked this question, ive posted it several times with no luck. i made my own system using a 1.0 gph oil furnace nozzle and a flojet 12 volt high pressure sprayer pump to inject a 50/50 alcohol-water mix the amount of alcohol delivered can be adjusted by varying the voltage to the pump with a rheostat (dash light dimmer dial) check these sites. http:/www.turbobuick.com/messagebd/ http://members.tripod.com/alcoholkits http://www.angelfire.com/ok/fwcdarth/injection.html

 

sorry, i havent got this www stuff figured out yet. duh!

 

A DIY kit is only going to be as good as the parts you use are good. It can be as high quality or low quality as you want it to be. The only downside is by the time you have all of your high quality parts together it ends up costing almost as much as the $200 kit. It's less headache to just buy one thing instead of ten.

You say the spearco kits pressurize the water container? Does it use a pump at all? What type of pump?

 

i am selling my brand new spearco setup for cheap. IM me if you are interesrted. it is partially assembled but never used. i changed from air/air to air/water intercooel setup so my charge temps will be pretty cold.

the speaco kit uses a simple small motorized pump, actictaed by a pressure switch. it doens't need a strong pump liek the aquaimist becasue you coonnect boost pressure to the tank...it pressureizes the tank and helps water flow.

 

I saw some kits on Ebay for like 100 bucks. I wonder if it'll work.

 

$100 is about what I spent total, so it can be done. Not sure what you would get from ebay tho. You can get a 60psi 12v diaphram pump from northerntool.com for $45. That way you won't have to worry about pressurizing your fluid container. That, along with the $30 needed for an adjustable pressure switch, is the bulk of the cost. I'm not sure how my DIY kit would compare to the spearco, but it sounds like it would be superior. Less cost, more trouble and effort though.

Edit: With a solenoid you're safe from hydrolock. Even without it you should be ok if you set it up right.

what about hydrolock? I mean how safe is it really, especially for higher compression? And wouldnt it rust things out? And what if it freezes? I would be a little iffie about it...

 

damn this post is old!...I remember this from a year ago!

As for hydrolock...if you get a good atomizing spray nozzle it should be ok...the theory is that the droplets would eveaporate way before it reaches the throttle body, breing the charge temperature down a few degrees.

 

So what if you had the water injection system and an intercooler spray kit? Would the spray kit be compromised by the water? I'm guessing that the water kit would be more of an advantage because i t prevents detonation and cools down the air! But would the spray kit cool the air more?
