Is anyone currently experimenting or using water injection?

 

To easy to just increase the boost.

 

97 i was thinking about that about a year or so ago when i start working on my 00. Most people were saying that it's just out dated. You might as well go with a VERY light dry shot of N20 (35hp is about as innocent as it gets). It will have the same effects as far as condensing the air, but will not have the engine cleaning benifits of water injection. That's just what i've heard.

 

Water injection is outdated, but alcohol injection is alive and well.

Go to turbobuick.com and read up on alcohol injection, they have a section for NOS and alcohol but everybody just talks about alcohol. Its a big deal on street driven turbo cars. Allows them to run a good 5 more lbs of boost on pump gas.

I had an SMC alcohol kit for for my lightning and then let it go to a friend with a Typhoon cause I thought the kit might be to aggresive. Now I wished I would have put it on and tried it. I will probably buy another and finish the project.

We went thru this about 3 months ago. Hopefully someone saved a link. The conclusion was water is needed whenever big boost is present. On a Turbo car this is only at high rpm and big throttle requests. With a blower motor water is required far more often and as a result you would need tons of water on board and that is a lot of water going thru the motor that may cause other problems. (rust, corrosion...)

Lots of the detonation is at tip-in right before the downshift. This ssituation happens all the time. If there was an aftermarket knock sensor that could be adapted..hhhuummm

after reading your post, I think I remember why I sold the SMC kit.

One of the things I gathered from the turbobuick forum was that when you step on the gas and the alcohol pump turns on then you had better be WOT or the engine will fall on its face, the pump supplies a lot of alcohol and the engine has to be at WOT to use it all.

But then I was thinkin you could make a 3 stg setup with different hobbs switches and oh nevermind

As a former Turbo Buick owner I have many friends that have experimented with the water injection systems with different levels of sucess. The SMC kit mentioned above seems to be the current favorite and works well once it is tailored to the vehicle. The greatest problem I saw was when someone would try to turn the boost up at the track and then spent the whole evening retuning the alcohol injection as it added another variable to the combination.

I think it could be used on our trucks perhaps with an rpm activated switch to control when the alcohol would start so as not to bog the motor down. Once again I think this would only be useful for those running big boost with modified bottom ends, ect.

I will add, heck with the alcohol lets fast forward to propane injection (the wave of the future race fans)....Naw nobody would ever run that on their Turbo Buick, Honda, or tow vehicle........would they ?

This is a little off topic, but at our little dyno get together in march, the dyno operator told us that a guy with a Dodge oil burner made over 630hp and 1200 ft lb of torque on there dyno a few weeks earlier and one of his power adders was propane injection.

Dale,

There is a local guy here with a Dodge dually runing low 13's high 12's @ 112mph weighing in around 6,000lbs!! Was told the dyno # were very similar to the ones you posted. This particular truck is running both propane and NOS as well as mucho boosto!!

For most of our mid - high 12 second trucks I don't see a need for much beyong the factory intercooler. I am planning a few upgrades such as a SPAL 7.5" electric fan on the heat exchanger (will be here Tue.) and hot wiring it and the intercooler pump for the track, adding a homemade power cooler and perhaps upgrading the heat exchanger for a front mounted volkswagon radiator. These add ons will be mostly effective at the track as the factory system does do a pretty good job as long as the truck is in motion and air is moving across the heat exchanger, I just want to help out the system inbetween passes.

 

Thanks for all the replies and thoughts. I have to admit I'm a little leary of running anything thru the roots blower. I think nitrous probably does make more sense. I've just heard alot about water injection lately, esp. with turbo applications(I own an '85 SVO as well).
