455 BBO water methanol setup Video!

[TheBigO]

Hello there Olds fans.....I have been away for a while.....But I am back now.
Here a quick vid on the progress on my turbocharged 455 BBO....installing the water methanol kit.......PLEASE comment any questions on my project and I will answer them accordlying,thanks.

Why do you inject water into the carb? im a turbo dummy so sorry for the dumb question.

[BIGJERR]

Why is a good question?

[Rok_StaRs_Bars]

I believe you can run higher boost. It helps with preventing pre-detonation under high boost. I believe

[BIGJERR]

Welcome to blowing the heads clean off the motor..........Please prove me wrong tho.......I always thought when you had to go to stuff like this your combo isnt right..........I take it you have run the turbo motor down the track and the numbers were not what was expected???

Water and methanol mix is what they used on the 62/63 turbofire. Allowed them to run something like 10:1 cr without blowing the thing up.

Yep then quickly lowered compression and moved along.........

Water/meth injection is a very common way to reduce combustion temps on a turbo car. I plan on running it on my turbo 4 at some point. The water, when atomized, sucks the heat right out of the surrounding air providing a cool clean burn and eliminates any chance of detonation. It also has the added affect of steam cleaning the combustion chamber. The meth in the mixture bumps the octane rating up. The combined effect is the ability to run more timing, more boost and have a cleaner, cooler running engine.

"Depending on the amount injected and the type of mix used (pure water, pure methanol or a mix of the two), gains up to 10-25+ points in octane can be achieved. Thus, making 91 octane pump gas act like 105-116 octane racing fuel in their engines."

I have seen alot of turbo cars that dont need this is all iam saying.....

[mechacode]

Yes, it's not a needed item but it widens the thin edge of tuning turbo cars run on when pushed to the limit.

With the 455 BBO and the Holset HX60 turbochager....left me with no room to route a air intercooler.....so the next best thing is a water methanol injection system....there are so many company out there that sell kits like cooling mist or snow performance.....Oh Ya...Snow Performance sell kits for normal apsirated engines check it out

It's quite popular in the street car crowd where you start making big power and don't want to run race gas. The turbo buick guys use it all the time. It's pretty slick technology. You have a knock sensor and adjustable alky controller in the car... you'll get notice if it knocks, give it a little extra alky and give it hell

Very cool man, get this thing on the dyno yet?

[bccan]

I've run water or water/denatured alky mix in a few normally aspirated high compression engines since early 80's & it makes a noticeable improvement w/preignition. Have a home made setup in my car now-vac switch set to appx 10" vac, washer pump & a nozzle from old Edelbrock Varajection kit. Use it in HOT weather if I can't get 93 octane, up a long grade or cruising in OD w/converter locked up on the highway when I would never hear some pinging over the stereo. My engine gets picky in hot weather if the coolant temp gets to 190 or higher. Only runs if I have it switched on & engine sees sufficient load.

No Dyno yet Still working out the tiny bugs out....Planning to install another wastegate(maybe). But I will take it out on the back roads....too see how the engine reacts to the water methonal mist.....and make a short vid under boost.

I have water/methanol injection on my GN. Works great. I can now run around set on kill 24lbs of boost instead of 17 (an extra 70HP or so on my setup) and not need race gas in my tank. Mine is set up to kick in after 10lbs of boost is crossed. It does not use a lot and saves a ton of money on race fuel or the embareassement of being caught with exscuses as to why my car is slow today. Couple thoughts I run a 50/50 mix so that their is no fire hazzard under the hood. Even to open flame. It can make almost as much power as straight meth in this type setup. Also if you are useing meth you have to have a kit / pump etc designed for it which is generally not the same as a kit made for iso alcohol. I don't know anything about useing this with a non computer controlled carberated setup.

Also straight methanol burns clear as in you cannot see the flame another reason I chose a 50/50 mix. Last it will dirty your oil faster and not just from more PSI to your rings so if you are useing it alot pay attention to your oil it can get black in less time than it would normally get dirty.

Thanks for the info concerning with the oil(my Olds only move around the weekends).

I use Peeks -20 washer fluid and the kit is set to turn on at 1lb of boost....the current 455 BBO has a CR 9.5.1 until I lower the CR for more boost( The Holset HX60 does not start spooling or boosting until 3,000 rpms, yeah...I know the turbo is a big heavy mother)

[chromefeet_withbeat]

damnit...why did everyone have to respond before me? water / methanol injection is something that is very interesting to me.

in response to big ol' Jerr, of course it would be nice to fill our gas tanks with 110 octane all the time and have huge intercoolers on all our forced-induction engines, but that isn't practical or realistic in many cases. that is either too expensive or not readily available for regular, street driven cars in many parts of the country.

injection systems and their potential simplicity and results have got me thinking about adding another point or few of compression to my 350 olds, if i ever take the heads off for a 3-angle valve job and some porting. one of the only 'downsides' to water/meth injection, if you can call it a downside, is that it has no benefit for a car that is not detonation-challenged when properly set up for maximum power already.

[Vern]

Sure it is Chromie you just have to be able to turn up the boost.

[chromefeet_withbeat]

yes, something my car lacks, unfortunately.

but it does have dynamic compression
