JTabora Posted January 21, 2005 Share Posted January 21, 2005 Anyone using it? If so, how well does it work for you? Thanks- JOE Quote Link to comment Share on other sites More sharing options...
Hugh Posted January 21, 2005 Share Posted January 21, 2005 I used Aquamist water injection on my last motor. It cuts out top end horsepower a little, but allows you to run higher boost without knocking. It also seems to add a little torque somehow. I've found that water injection is great, as long as you tune around it. If you have an already tuned car, and then throw in some water, it will just make it slower. If you back off the fuel and lean it out a bit with the water in there, you will start to see the benefits of it. It's great if you run your injectors near their limits. Leaner running at less duty cycle, and the water does the cooling instead of dumping fuel. Intake air temps drop nicely with water in there as well, probably accounting for the gains in torque I bet. So if you just throw it on the car and expect it to work wonders... its not really. However, if you're running non-intercooled, it make a nice replacement for the intercooler.

Scottie-GNZ Posted January 21, 2005 Share Posted January 21, 2005 I am currently upgradng my car to use alky injection and should have it completed this weekend. At a minumum I expect to match my top HP number (520rwhp) with 93-octane. C-16 is now $9.25/gal in my area! http://www.alkycontrol.com/ Quote Link to comment Share on other sites More sharing options...
JTabora Posted January 21, 2005 Author Share Posted January 21, 2005 Thanks for the input guys. Scotty, let us know how it works after you install it. Quote Link to comment Share on other sites More sharing options...

dr_hunt Posted January 22, 2005 Share Posted January 22, 2005 Scottie, it was for you, sorry, it was a little confusing. I've been looking at EFI and Accel's new gen 7 will support Alcohol inj and they have low impedence injectors up to 160Lb/hr, so on Alky it'll support 1280HP NA and probably close to 1000HP Forced. Alcohol has such a large latent heat of vaporization that it will cool the intake charge dramatically. On my NA cars, the intake will get condensation on it, it is that cool.

speeder Posted January 22, 2005 Share Posted January 22, 2005 Scottie, what Water/Alky system are you using? I Have a "Cooling Mist" setup that I'm planning on installing on a friend's car- I'll be very interested in results. Quote Link to comment Share on other sites More sharing options...
getZ Posted January 22, 2005 Share Posted January 22, 2005 does anybody have preference of alchohol over water (for the car not for you). My understanding is water has a greater capacity for absorbing heat in the combustion chamber but alchohol does a better job cooling the intake charge.

Scottie-GNZ Posted January 22, 2005 Share Posted January 22, 2005 Rick, I am using the system from Alky Control, http://www.alkycontrol.com The owner is a friend and fellow Buick turbo enthhusiast. I am going to see if I get him up to the SEZ to help promote the product. dr Hunt, 3.8L Buick turbo longblock, +.020 hypers, ARP rod bolts and head studs, CNC-ported heads and intake, mild cam, 75# injs, 57mm TB, turbo - 66mm compressor/p-trim turbine with .63 housing, FMIC, 3" DP and exhaust, 9.5" 3400 stall convertor, TH200-4R (BRF), 3.07 final drive, stock ECM with Translator+ and LS1 MAF. See sig for best time which factors out to about 520rwhp and still manages hi-20s mpg cruising. Drivetrain now in a 2nd-gen RX7. Quote Link to comment Share on other sites More sharing options...

510six Posted January 22, 2005 Share Posted January 22, 2005 I have a friend who ran 22 psi of boost on His Eclipse with a 20g using pump gas in California 91 oct.http://www.snowperformance.net/ was the system He used .I am going to setup my own system using parts from http://www.coolingmist.com/ and an additive from http://www.klotzlube.com/ to controll corosion.I will be using the boost /voltage controll unit from Snow Performance to controll variable amounts of methanol and using a NOS solenoid controlled by the AEM EMS I will be using at lower boost levels.http://www.mcmaster.com/ on page 1904 sells misting nozzles for around $5 apiece.Hopefully I will be able to run 400rwh on the street with the new turbo and pump gas.

spork Posted January 23, 2005 Share Posted January 23, 2005 check out the turbo buick webiste http://www.turbobuick.com/forums/forumdisplay.php?s=&forumid=14 this will put you into the water/methanol injection forum and read up on posts there to educate yourself. To me, it looks like the guy named "razor" has one of the better kits. Heres a link to his site. http://www.alkycontrol.com/?ref=turbobuick he uses a progressive controller that ads more water/methanol as you build boost, that way you don't get a sudden shock of methanol when it turns on. I'm currently running a cheaper spearco kit on my car and plan on upgrading to Razors kit as soon as money permits. Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted January 23, 2005 Share Posted January 23, 2005 To me, it looks like the guy named "razor" has one of the better kits. That's who and what I was referring to. The progressive feature is why I am using his kit. Anyone can make an inexpensive DIY kit but if you are looking to run big boost/HP, this is the correct way to do it.

510six Posted January 24, 2005 Share Posted January 24, 2005 I was just going to buy one of these units http://www.snowperformance.net/proddetail.asp?prod=auto030 and piece together the other parts from various sources. Quote Link to comment Share on other sites More sharing options...
Bernardd Posted January 24, 2005 Share Posted January 24, 2005 Is there any truth to the myth that the L28 head suffers with water injection? I've read it looks like swiss cheese after some time. I've never seen pics or anyone that's actually got evidence. Quote Link to comment Share on other sites More sharing options...
speeder Posted January 24, 2005 Share Posted January 24, 2005 A properly designed water/alcohol injection system does not harm any engine, including the L Motor. Back in the days (70s) when I couldn't afford an intercooler I used water injection on my 280Z (Stock L28 with a BAE turbo Kit) - the only visible difference it made was that the chambers, piston tops, and valves looked brand new when the head was pulled to change a gasket.

Guest 81na ZX Posted January 25, 2005 Share Posted January 25, 2005 At worst you'd hydrolock, which won't break the head. rods, pistons, valves, bearings, yes, but water isn't gonna bore holes in the head or anything. When its working good, you'll get a nice steam cleaned combustion chamber (and intake trac) Quote Link to comment Share on other sites More sharing options...

Sorry man, I wasn't absolutely sure that this was the same kit you were referring to. I know when I've got the money, I'm getting it, I hate paying for the c-16 also!

Scottie-GNZ Posted January 29, 2005 Share Posted January 29, 2005 Finally got around to taking the car for a spin to test out the system. HOLY PUMP GAS, BATMAN Filled the tank, turned it on with the default settings and hit the gas. 22psi boost straight out of the box and the EGT was less than 1500*. Next, hook up the LM1 and start playing with it but first I have to bleed the brakes some more from installing the braided lines and install some new ball joints.
