Did any of you guys with water/meth injection using BHR's throttle bottle spacer?

nope.

Wrong, again, Denny.

I think Rote8 bought one, but it's currently sitting in a box in his garage. I'm not sure if anyone else bought one.

It's a pretty nice piece.

I have one installed - pix are kinda old but show the location

Rote8

I like the hose color, where did you find those?

And yes, I do have the spacer, I may use it again as a longer intake is always good.

ah dang---see what i know---
i do know most people also install a w/m nozzle AFTER the blower.
So there!
Happy New Year Ray!

You may want to consult those who have designed the various alky kits to see what they suggest through their own real-world experiences, as I have.

olddragger

iTrader: (3)

ok Ray --what do you suggest?
OD

Rote8

60 ml nozzle pre blower, 100 ml nozzle after the blower.
we have had best results with the 100 ml nozzle spray pattern hitting the inter-cooler through the outlet. (mount it on top or the rear of "the hump"; I/C side)

You should also insulate the bottom of the blower, the engine heats the S/C through radiant heat unless you have some heat reflective material.

i know---just wondering if Ray has more "ideas" to share.
The throttle spacer he has is a nice piece but i am afraid that with the size of my airfilter it will take up to much room. Plus I have found that if the nozzle is too close to the TB a residue will build on the butterfly and the backside of the TB.

The spacer goes behind the TB, so no residue can build up.

What are you spraying that causes a residue, anyway?
Distilled water and and alcohol shouldn't be carrying anything that can build up.

Rote8

Yes, the residue builds up using the BHR spacer.
Anytime the throttle closes the alcohol mix in the intake tract is dispersed, including to the back of the throttle plates.

Boost-Juice leaves a pink stain, nitromethane leaves a brown stain, pure water methanol doesn't leave a stain.

I could install the spacer due to my cold air setup, but it is no longer needed, I have already tapped the intake for the methanol injection.

Update:
Residue has nothing to do with spacer, as Charles said.
High vacuum from throttle closing disperses the vapor to all points of the S/C intake track.

Charles R. Hill

Plenty, Denny.

If whatever mix you are injecting has the potential to leave a "residue" that residue will appear no matter where you place your nozzle. The spray pattern emitted is perpendicular to the flow of air and the plume is rather large because the objective is to vaporize the mix as quickly as possible. The visibility of residue is not indicative of a problem caused by the spacer and when alky or nitrous injection is programmed properly the throttle body is of little/no concern because injection only happens at WOT.

Even with unmodified RX-8s, a grayish residue will build up on the backside of the TB plate, especially at the outer edges of the butterfly, because that is where the highest negative pressure appears during most driving conditions and where any dirt has the greatest chances of becoming attached. Matter of fact, the entire UIM will see this same build-up if given enough time.

As for fitment, I thought the S/C owners were transitioning to some sort of manner in which to relocate the air filter from under the hood to behind the front bumper cover, as someone else first did and as I subsequently did on Phil's car?

I think Phil and Rote8 are still the only ones running a CAI setup with this kit.

Rote8

I like mine there.

after speaking with eric about sand dust and looking at used oil analysis i have changed my mind--mine is staying in the engine bay and i am ditching the k&N and looking for a paper element type.
Water meth nozzle 60 size has clogged more than once--reduced flow type of clog.
need to pay attention and turn the system off before shutting the engine off
we are using it way before wot.

I thought it was a bad thing to install the w/m befor the S/C !
someone told me to install the noozle only after the S/C or else it might damage the S/C ???

original question:
Should the vdi line, coming off from next to the black connector in the vaccum tank thing, be blocked off? If so why? Sorry for the dumb questions.

its not open, its routed same as before the sc went on,

searching around i've seen its been capped off, why is that?
i've been running with it connected, is that a problem?

Flashwing

Besides my UOA, what other ones have you seen that had sand/dust issues?

I have yet to check my filter but remember that my sample of that oil wasn't taken in the greatest fashion. Most of the sample was dripped from the pan bolt so it's possble I picked up some dirt particles from the oil pan itself.

eric has blown 2 engines in Daytona and actually they found sand in the engine, Speedsource has done the same. It was k&N filters ran outside the engine bay. They had other material on the k&N to supposedly block the sand and dust. the 1st engine didnt last a day, the 2nd the same. They both have oem style boxes now with paper filters. The flow difference is insignificant.
So I 'm figuring that k&N is not a good filter to run constantly outside or inside the engine bay. Plus my uao was higher than normal in certain metals that can suggest that the air wasnt filtered well.
thats my story and i am sticking to it.
OD

Flashwing

So I guess where I am going with this is: Is this a problem with the K&N filter design or simply with the filter location? I'm using the AEM dryflow filter so it's designed to not be used with oil.

I'm sure AEM has filter sizes that would fit your application so that's an option.

olddragger

iTrader: (3)

agreed---the short time frame to blow the engines where due to the filter placement--like a mazdaspeed cai location.
But for a daily driver and many more hours of running time i rather be safe than sorry and run a paper type.
Correct again--i am looking at the AEM and the Airraid.
Right now i have a fine filter shop vac bag wrapped around my K&N.

Ummm SS's intake has been always in the engine bay, and thier engine blew last year not because there was sand getting through the filter... As for eric, dont know his circumstances were but playing bumper cars couldnt have helped...
Now Im not saying it wasnt a factor, but I would not pin one symptom to a blown engine in the highest speed endurance race of the year,,,
