So I did this to contain more crankcase fumes.


It significantly changed the sound when my blow off valve opens. Is it possible that this tube makes compressor stall more audible?

 

Well, nothing seems any different besides the BOV sound. It's almost like phaser fire "Pshhowww" not sure why.
I will say that the crank case fumes are almost completely gone. Really only a tiny bit when the BOV opens, maybe if I recirculate, I could get that too.
I am thinking about heating my BOV spring in a vise as Deezums suggested somewhere, maybe it was Aidandj. We if I can get more adjustment out of it.

 

Amazing build good to see more people having a crack at the drags good luck getting your 12 second pass

 

Still testing very well. I am convinced that I have some compressor stall/surge but the car is performing flawlessly otherwise. It must have been there all along but I think I can hear it better now.


Does this mean I don't have to sit at the table with the 1.6 guys?

 

On my 101st 1/4 mile I ran 12.88, I would say that this thing has passed it's beta test. I think I am close to 15k on the kit so far.

 

New best times and trap speeds.


Obviously I am car 62 no 11's yet.

 

I hooked this up hoping to gain trap speed in the 1/4 mile.


My log seems to suggest that it actually hurts my IAT while going down the 1/4. It helps cool down between runs, but the water must interfere with the cold airflow somehow at speed. My IAT'S increased 10* when I misted in 3rd and 4th gear over not misting, my intercooler sucks.

 

How high do your IATs get?

 

I typically pick up 45-55*F on a high 12 second pass but today I was picking up 60* while spraying. Disabled it and it is closer to a 50* increase again.
I can easily fit a larger core, or a better one.

 

How in the world did I miss subscribing to this thread? Well! I'll soon take care of that!

​​​​​​Re water: Maybe its loading up in the core, blocking airflow and holding heat? Or windmills do not work this way? The only water spraying I've ever dealt with was blowing radiator hoses

 

that's REALLY interesting about the mister actually hurting the car.
cause so many people actually use something like that thinking it helps

 

Yeah, I wonder if I had a finer mist or perhaps a few pulses of mist rather than steady mist.
I do think that the water is loading up the little turbulators.
I will probably play with it a bit more since it's free to play around with while I save for tires.

 

You should install that mister into your intake stream, and feed it with a meth tank

Joking aside, I am surprised it raised temps, maybe you are seeing the affect of sub-par core. But either way, nice 12 times!

 

maybe it's squirting too hard

 

Yeah, I don't mean to discredit the idea. Just my current implementation of it.

 

Is it A-B B-A repeatable? How many data points are we looking at here?

Ooo! This is fun!

 

So I only have 3 logs of me squirting pretty hard 3rd and 4th.
I have tons of dry logs showing an average increase of 50*F per 1/4 mile pull, regardless of ambient temperature.
I will do some comparisons between logs. IIRC the IAT log was rather unusual when squirting. It is usually an even climb in temperature, but squirting causes variation in the rate of increase. However ultimately leading to a bigger increase for each of the 3 squirting passes.
I will devise a new strategy and waste a few passes on this next week, if it actually doesn't rain on Wednesday. I might order a couple of real mister fittings from mc master too.

 

The misting device is on hold for the moment but I did manage to get my air filter out from behind the radiator.
Not exactly thrilled with the configuration. First off the throttle is a bit close to the air filter for my comfort Additionally everything is basically packed like a can of sardines in here now and I still want to recirculate my BOV.
Of course there is slicks, ms3, motor, ect... And the list goes on and on.
Last regular drag race of the season tomorrow, not sure if this will help or harm but at least I will get some good data.

 

Air to water intercooler with an ice tank in the back.

 

I am kind of glad you guys didn't get to meet my wife yet. Otherwise she would be saying "why don't you do what Aidan said? You can stop by my work and pick up methanol and dry ice for your IC tank."
Maybe next year
