remote turbo rain issues
 

Has anyone else had problems sucking up water in the rain? I had never had problems until I tried to drive back from St. Louis yesterday in constant rain. I though my filter was in a pretty good spot, and it also has an Outerwears cover on it. But I still managed to suck up enough water to cause a misfire. It was no fun driving all the way back at 50mph( normally takes 5.5 hours at 70+mph). As long as I kept the engine load and RPMs down, I could keep the water in my intake piping from being blown in the intake manifold- and that magic spot seemed to be at 50mph in 3rd gear keeping the vacuum at 10 or greater. When water would get in, the engine wouldnt fire and the excess fuel being dumped just ignited in the exhaust and spooled up the turbo.

Now this Outerwears cover seemed to do the trick when I first got it, but I guess the constant water from driving on the interstate overcame the cover. Whe it got soaked, it seemed to suck up some oil from my filter. When the OUterwears has any oil on it is seems to be useless. It did take about 120 miles for the water to get to the engine, and I am not sure how much water is in my intercoler at the moment.

This is just a warning for anyone who might think they dont have to worry about water with their remote turbo's filter. Even though mine is about 24" off the ground tucked into the body, it still sucked up water.

Your outer ware probable has lost it water repellent. Take it off, clean it and spray it with Scotchgard. That will freshin it back up. Your probable not really getting much water, it only take a drop on the MAF to cool the little wire and make it read 0. I ran my STS in the rain ALOT and never really had much trouble with water, unless it was really raining alot and I got on it to much.

Also, drill a small, like 1/16 hole in the lowest spot of your intercooler and that will let the boost blow the water out and won't be big enough to cause any other problem.

My Outerwears had less that 300 miles on it before this trip..

Put a snorkle on it, or plumb it into the cab, lol.

I always had trouble with rain too. My filter was in the fender well and I had no fender liner. When it rained, the car would barely run. As you said, the only way to keep the car running is to keep the rpm and load down. After adding the fender liner back in (and preventing spray from the tires), the car drove just like stock. I would be very cautious about rear-mount turbo kits for just that reason.

I'd still re-Scotchgard. It seems to work better then the stuff they put on it.

what he said.

I drilled a small hole in the intercooler as well as the lowest end of the charge pipe for condensation drain. I haven't had any issues, I hope you get your problem fixed.

I havent had any problems with my kit.... but i got this lil cool aluminum guard i engineered in about 5 seconds......... :judge:
