More of a curiosity question here, but I've noticed that when I do HPDE's that washer fluid runs down the rocker panel on the passenger side. It also looks like it's squirting out of the nozzles. I was at Gingerman last night for their test and tune. They've lengthened one of their straights and I'm now seeing 120 down that stretch. I'm wondering if there is some kind of negative pressure in the cowl area at those speeds that creates a vacuum effect, essentially sucking the washer fluid out of the nozzle? Obviously I'm not looking at the lower part of the windshield so I haven't seen it actually happening, I just see the dried spray on the windshield and the fluid down the rocker arm. It's gotta be coming from the nozzle's since the tank is on the drivers side. Anyone else seen this before? More of a curiosity question than anything.

I guess this explains why I keep getting the low washer fluid warning on the DIC even though I never actually use the washer fluid! I just figured it was evaporating from the heat from the headers or something!

On a side note, I put a new set of Nitto 555RII's on last week. Last night was my first night on them and all I can say is Holy He!!. They're like putting on a frickin' super suit!!

fresh R comps have that effect

Install the Ford one way valve between pump and wipers,or pull off hose and plug plastic tubing for the event.

Both good solutions. I never realized how much was leaking out of there. So is it being sucked out at high speeds? I can't be the only person this happens to?

John Shiels

yes the speed is to much!

Water weighs about 8lb/gal. Why carry that weigh around? Dump the fluid.

Mine will slowly streak up the windshield at speeds above 120mph.

But I might want to clear bugs driving to and from the track..... or, I'm just too lazy to bother taking it out and putting it back in for track days.

I just bought the same tires to replace my AZENIS RT-615s and I'm hoping to have the same feeling. What tires were you on before?

Good thought! And that weight sits up pretty high too. But, I digress, some fluid for bugs is good to have on hand.

I like the idea of using vacuum hose caps or the like to block the supply elbow at the cowl.
