Hey William! Do you have a toad yet?

You reckon that thing might understeer ?
Wouldn't fit in the trailer Bruce, only made it long enough for the 5 door SGV

If I remember in NSW, scrap metal merchants were stopped being able to buy wire with the casing burnt off. As there was too much wire being stolen, even live wire was being cut down. If the case was still on it could be traced.

I have been thinking about all I have heard and read (here and other places) and am now thinking a bit differently.
VP air intake is now high up at the rear, not roof top as it is on the side but that could be an option if there was any benefit.
Currently it is a 5'" 1/2 cup that will assist air flow with motion along the road
.
What I am trying to gain here is the big performance increase that happens when driving in the rain, from the cooler, more humid and more dense air getting sucked into the intake. I am not trying to extract the last possible HP from a dragster engine.

So, I am thinking that the air intake should be the point of injection, it adds a lot of extra travel for evaporation and does away with any concerns about solid water entering the engine (and is real easy to do).

There is a big pre cleaner as part of the big air cleaner where any rain entering the intake is captured and dropped out a duck bill fitting, so this would catch any solid water particles.

After all, solid rain is getting sucked into the intake when travelling in rain, so if we injected mist at this point I can't see why it would not give us somewhere near the rainy driving increase, as the air would become both cooler (from evaporation), more humid (same) and more dense becasue of both of these.
Have I overlooked anything ?

I think you might be on the right track here Bill, if the mist is very fine and across the direction of airflow I think it will do the job quite well. The fans in the eating area at the Crickey Zoo use water misting and it is very effecting, but very high pressure pumps and very fine misting nozzles

[Busman]

We did a fair bit of propagation fogging when we were building greenhouses where they were trying to recreate rainforest conditions, so I have a shipload of nozzles left. We used systems that ran at 1,000 psi and it was literally fog. It will be interesting to see what sort of mist we can get at 160 psi, which is the 24 v pump I have, will just use 6mm air line and push in fittings to see how it works. If successful will look at a higher psi pump and heavier tubing. Getting all the bits together now for a trial and if looks good will fit it up.

[bagmaker]

When would you fog? Would you have a microswitch on the throttle or something so you only getthe misting at higher throttle settings?

[Toolman]

I think that the trick would be to use very little water, and you could control the pump with a boost switch It will be very interesting to see how much difference that a mist setup makes

[Busman]

Crap, did a long post from home and now its gone !! Grrr !!!!!

Well I have tried it with one nozzle and it is a lovely fine mist, this is with a 160 psi pump which keeps cutting out. So I need a bypass and/or another nozzle but I have to get some other fittings to be able to do that.
Will be just a fine mist, controlled initially with a manual switch, if it gives me an improvement I will look at a boost controller that changes pump speed.
At the minute just cobbling together bits to make it work, if successful will do it a bit more betterer.

Here is a propane injection post from a guy who runs a yank old bus forum, just added to his second bus and is pretty happy, just uses on the hills

Commig south into elesibethtown ky on I65 a good long grade last time I crossed the peak of it I believe in the 40 mph range. Lots of black smoke and lifting of the throttle while slowing down... With the propane I never dropped below 65 mph never any black smoke and less then a 5 deg or so engine temp raise which was way less than 10 deg climb without the propane

I don't expect the same without adding methanol, I may do that if I think it will be worth it, but probably not
