Outer Limits 4x4 Board

Hi I remember reading a while back about plumbing compressed air into the dizzy cap on a TB-42, for when doing river crossings, tried seaching but could'nt find anything, any help with this info would be great as I am just about to install endless air system and would like to fit this.

Never done it myself, but I think the endless air would be too much pressure for a dizzy, I think most guys use a real low pressure cheap compressor, It'll only be on for a minute or so at the most.

dont matter wot size compresser you run, just put a reg before the cap, many out there, used to have some speco manual regs, a fittin with a valve, screw in lower pressure

Hi, thanks fella's, I will try fitting a regulator jut b4 dizzy cap.

What about an air horn motor? I was thinking of trying one of those.

I've done it, works well with both electric and endless air, just put a reg inline b4 it hits the dizzy

I did this trick with an air locker solenoid on a couple of rover v8s and was going to do it with my mate's comp truck but was advised that is was not needed on these motors; under advice we just put a hose from the breather into the cab so when it gets wet and wants to suck air in it comes from dry cab not wet engine bay, we did a comp with it and did two laps of a 1km long knee to waist deep water/mud section with TB42 turbo and never coughed once, so VERY impressed, worked a treat. May save you fair bit of hassle? He does use this site so may have further comments with it??

Was told this works better and some motors than others and the TB42 is one of the lucky ones...

We used to use air horn compressor, run larger hose in, smaller hose out, main reason for it is not to stop water in, but stop a sealed dizzy from condensating with temp change when water hits it.

We also used to use a big rubber glove and run the leads out through the fingers as extra cover over the dizzy and leads, cable tied around the dizzy, and the lead where it went out through the fingers, and we used to use 7mm boots on 8.8mm leads to prevent water and spark issues, and use boots that covered the whole plug, as they plugs would misfire even if the porcelain part was getting hit with dirty water.

Later changed to fully insulated 12mm top fuel leads for better resistance to spark jumping as well.

Clean water is not as much of a problem as dirty water, the dirtier, the more spark it steals.
