Snow water/methanol injection

[Budnicks]

I just watched the Horsepower show on Spike TV, they had a cool 2010 Challenger, highly modified engine, that they said had, head work, camshaft & compression change, with a Centrifugal Supercharger {not sure the brand} with 6psi boost, making 543hp @ the rear wheels "base line", they added a Snow water/methanol injection kit, it added 43hp at the rear wheels, with the same exact set up, no tuning, just adding the Snow w/m kit, something like 60+hp at the crankshaft... Impressive #'s for just a water/methanol injection kit addition, if they are real #'s... They also did a Big block Chevy on an engine dyno it made 40+hp more with w/m injection at 40 degrees of timing, with a ton of tuning, they tried it at like 30 degrees ignition timing & didn't get very good results, like 20+hp... I thought it was kind of interesting...

Only practical if you have a dyno to make all the changes on though when using a carb.
They also had to change jets before adding a boat load of timing..... The engine made less horsepower than baseline with the kit added out of the box...
It also doesn't use the spray below 3000+ rpm... How does the engine hold up with that much advance and the leaner fuel mixture with jet changes when it's not spraying?
I like the fuel injected cars using it because they monitor and adjust fuel mixtures and timing automaticaly... I watched the episode when they put the supercharger on,,,, I dont recall any other mods to the engine,,,,,,

I like the fact that they re used the stock windshield washer bottle for the meth/water mix saved having to plumb up from the trunk on the chally

I have seen this tech before it's similar to propane injection all I can say is if it worked on the P47 in WWII in can work on your muscle car.

It was also nice to see that they made a set up for naturally aspirated motors. That would be a blast to run set it for 3500 rpm and watch the temps drop and the tires smoke lol

It was funny to watch how long it took to figure out the 572 cheby motor lol changed jets, changed timing like 4 times lol haha cheby lovers:sleepy2:

i have a buddy that is running it on a jeep with aftermarket fuel injection.he sais it is the greatest thing ever.i think it runs best for forced induction or fi so it can adjust the mix.the problems they had with the carbed chevy big block are a perfect example of that.what happens to your eng if you run out of mixture?how lean does it run with a dump load of advance?stuff is great for specific applications,but not very practical for carbed performance.

I am not saying it's good or bad, just that it was interesting to see it done, I have experience with the carburetor equipped version many moons ago, I don't remember which brand, but it was a total pain in the a$$ to keep tuned properly... I had a few friends that were into turbos that loved using the water/meth* injection & swore by it {*windshield washer fluid}... I do see the great advantages on the EFI set ups though, you have the computer & sensors to compensate for everything tuning wise... I'm not bashing Chevy at all either... The fact that they went to 40 deg.'s ignition timing, to get the best power results, Hell when I was running/racing BB Chevy's for many years, 38-40 degrees of ignition timing was common place, even with high compression gas race engines & especially alky {remember alky needs around 170% the volume of fuel compared to gas & it burns much slower & much cooler, so you can run more ignition timing} or blown alky combos, we would just back timing out as it went down track or up in RPM's, they {BB Chevy's} seem to be able to handle & like more ignition timing, than our Mopar wedge engines do... The carburetor tuning issue... Like any addition to the fuel system or ignition timing changes, the ignition timing/tuning, add or subtract squirter size, accell. pumps/cams & jetting, etc. is always a must do, if you want the best out of your carburetor set ups, hell any little altitude change, even will effect your tune-up, with carburetors, you just can't avoid that issue...

I'm just about finished installing my system,I'm not going to have a problem advancing my timing.I'm sittin at 33 total right now with c-12
