Ok Im going to get the blower next month and here is my setup Im plan on runn

JRSC with 9lb

Forged internals 9.5 weisco pistons with eagle connecting rods

Im going to go with Greddy E manage (Im SS prelude)

Ok my qestion is since there is no Intercooler for this kit would water injection work? If you look at the parts list it list all Hondas excpt Preludes ok I seen a prelude on the web with water injection now would it be hard to intall?

Thanks

 

water injection IMO is not ideal for cooling the intake charge. From what I've read on this topic, it didn't seem like the best solution.

 

which would be the best way in order to keep the intake charge temps down?

 

jrsc for the prelude... you'll just have to deal with hot intake temps since there is no charged air cooler. they really should try to make one... lowering temps by 30 degrees would even help prevent as much heat sinking.

You'll be hard pressed to find room for the water injectors if you want to put one in each intake runner (the only sensible way to run water injection). I don't know of anyone who has done it on a JRSC lude yet. One guy I know was looking into having custom water injectors made to fit on the underside of the intake manifold, but the expense was too great.

Not sure I would want to run water/alcohol injection on a daily driver.

 

yes i know this isnt an h22a but we can all learn from the install.
im a firm believer in alcohol injection over water injection.

Injecting alcohol (depending on how much) actually leans out the A/F slightly because of the additional oxygen it contains. Since it also is a fuel, even more gasoline can be pulled from the fuel map. The only reason this can be done is because alcohol has raised the equivalent octane (knock threshold) of the pump gas being used. Alcohol raises the equivalent octane rating by greatly slowing down the "burn" time of the gasoline. That is the same effect that high octane race gas does. Since the burn time is slower (spread out over a longer time) more ignition advance can be used, which in turn, significantly lowers EGT.

So I would think it makes lots of sense to run this on a daily driver or race car. You dont have to spend the extra bills buying high priced race gas when you can buy a 3$ gallon of alcohol at walmart and have the same if not improved performance.

I agree that water/alcohol injection works well. However, I would only set it up as direct port, and there is precious little/no room for that with the blower in the way on the H22. Further, because running out of whatever fluid you are using can be problematic, I wouldn't do this on a daily driver. Just my opinion.

 

I thought of an idea on how to put an intercooler with a jrsc. I dunno if someone's already thought of it though. You know how you can hook up a cold air intake to a jrsc. well, what if you extended the pipes to an intercooler to another pipe then filter.

Something like Filter(Driver side)&gt;&gt;&gt;intercooler&gt;&gt;&gt; pipes(Passenger side)&gt;&gt;&gt;TB/Jrsc. Can that be done?? Or would it be a waste??? What's your input??

 

endyn makes an intercooler for the jackson system... I will try to find a link of it and post it for all the nonbelievers

It wouldn't work, unless you were spraying the cooler with nitrous or running icewater through its core. Otherwise, the lowest temp you could get the air down to before being compressed by the blower would be ambient, which it is already at before the blower.

 

lets see that cooler made by endyn i want to see one for a jrsc

 

I'd buy one today if someone made a kit for the H22, but I've never seen/hear of one.

 

Well the stupid internet window crashed when I typed out a long response, so here's the short version.

I disagree w/ Shark; i believe water injection would be good to have. It does not need to be mounted in a direct port manner, so space wouldn't be a concern; just stick a GOOD single nozzle in the intake.

Water injection won't really drop the intake temps much, but it will help reduce knock a good bit. It is a nice safeguard to have along w/ OTHER precautions.

 

The problem I see with water injection before the supercharger is that, the huge increase in air temperature happens after the air is compressed, not before, so there would be little drop in air temp by the time it reached the combustion chambers. Also, I could see the intake air temps not being near hot enough to convert the water into steam until after the supercharger, and that could mean you actually are just spraying water into your supercharger and having it try to compress it. We all know that's not good.

Read up on how water injection works; you'll see that it doesn't quite work that way.

 

I understand that a fine mist of water is sprayed in. But the intake air temp has to be hot enough to convert the water into steam. Though I guess the supercharger would get more then hot enough to convert the water into steam, I just don't see it doing near as good as if it where inject after the supercharger.
