Water injection questions
Do you guys think it would help my truck with a 4lb lower? I go to the track maybee once a year.I mainly street race so do you guys think the intake temp would already be up high enougth to help with the injection.
If the tank is empty I should still be able to pass tech?
The alcohol/water doesn't have any effect upon the intake air temps before or after the intercooler. It does cool the cylinder temperature. The EGT temps are way down when you spray this stuff. I was thinking about sticking in some TR6's now...
I may post some pics later this week.

Know you said the Lightning kit isn't ready yet, but could you give us the company's name or website so we can track progress. This kit is something I am really interested in, especially since the octane up here is so D@mn low. The detonation prevention alone is pretty attractive, but add more timing and boost and this kit is almost a must have.

Did you add any timing with the water injection? If you keep the tune the same there would be little difference. If you can run race timing on street gas with the water/alcohol injection you'd have to pick up performance. There's over 30 hp difference and almost 40 ft. lbs. on my truck between the 91 octane tune and the race tune with the same boost (6# lower).

I was running 12.5° timing on the street setting. Now I am running the race side of the chip on the street with 20° timing. $10 a gallon for alcohol sure beats $7 a gallon for C16 especially since I don't have a fuel cell.
I think it may be against vendor rules to post a link to the guys web site, but the kit is an SMC Enterprises kit and here is a link to a good site about water/alcohol injection. You can also find out about his kit through the grand national guys. I believe they run his kit on their club car.
Steve gave up his Saturday working hard to get the kit and controller to work on my truck.

This is the exact info I was looking for. I've run water injection in the past with excellent results. Wanted to hear from someone who could run a race timing figure with pump gas and water/alcohol injection. Seems like a no-brainer to me versus buying Xylene or Toluene in drums.
Thanks for the info! I was going to do it anyway, but you just pushed up my timetable.
Hmmm, sounds very interesting. Looks like something I might want to look into. Bring up the boost to about 18-19PSI with some water injection.
550-560RWHP on a stock block anyone>???
Sounds like fun to me. Easter, was any time frame given to you on when the Lightning specific kit should be out>??? Thanks. -Mat-

When I first installed the kb I mistakenly ran the truck on the race program with IT-24's and 93 octane and a 2.5" upper and 2lb lower(21-22 psi). I hit the gas the first time and 7 of eight plugs were destroyed due to the detonation. I have BR7EF's now, but those may be too cold for the lower cylinder temps the alcohol gives me. So I am going to try some TR6's today.

I made the suggestion to Don at Modular Madness about running TR6s. He has good luck with them at 25#s boost. Id be interested in seeing how it works out for you Easter. My IT-24s , gapped at .032, have worked good for the last 4 months, no problems. With the TR-6, would you still run that tight gap? R&D is what its all about. With my a/f at 12.2, by increasing my alcohol concentration and going with a .6 jet, I am basically bringing my a/f down to the 10 range. With a .4 jet it seems to feel much better, especially upstairs. So I think I will try the TR-6s with a .38 gap and a .6 jet at a 70% alcohol mix, I believe this will be the optimum tune or close to it. This is the kit I got: http://www.syclone.freeserve.co.uk/waterinjection.htm
Promod, I just got finished gapping a set of TR6's to .040. I was running JDMs chip earlier this year with TR6's and a .036 gap and had no problems with 18 psi.
I stuck a couple of pics of the kit in the F150 photo gallery under my name. The wire mess is my doing and doesn't have anything to do with the smc kit. He uses nice connectors.
