I wired the pump into my hobbs pressure switch to come on at 11 psi with my 5th injector.
wow thats a great idea.

How old is that washer reservoir, if its pretty old it might crack with too much force. Im sure it doesnt have that much pressure from the battery though. Just something to think about

Looks great

Throw some ice in there and take it back out

Also what sort of a pattern of water does it shoot Brandon? You want it to hit most of the intercooler when it sprays not just one spot.

excelant idea Rebel....I too have to run with my stock turbo for a while...so I may do this mod too....the idea with the ice is a good one, the ice would melt eventually...but the water that remains after the ice has melted would take longer to warm up....great for track use....just before the run throw some ice-water in there and go, then mabey even try a run without having the cooler filled, and compare the track times, with cooler=???, without cooler=????,
I was thinking that making some sort of "air induction" right in front of the turbo (or a scoop on the hood....but it would look funny mounted above the turbo), to externaly cool the turbo with outside air.

PS: I think you would notice the gains from this mod with boost levels higher than 13psi's, because ive noticed that anything over 13psi's my boost will start to drop as the rpm's incresses...i figure this is due to the little stock turbo getting too hot and not being efficant (sorry sp), at anything higher than 13psi's. So I think that this mod will help keep that boost from droping off at boost levels higher than 13psi's.

Someone needs to try the water/alcohol injection system

I wanna see the gains, if any, than can be had with it on the F2T. People say the turbo gets unefficient at high boost levels... well thats one way of bringing charge temps down and reducing the chance of ping/knocking. Not only that but it also cleans the inside of yer motor rather well :D

I too have heard of the water/alochol injection system as a way to reduce knock/pinning at higher boost levels...but I haven't heard much about it. Also I can see this system only being good to reduce knock/pingning and not really cooling the intake charge down..but then again I could be wrong since I haven't done much research on this system.

Here ya go for the 90th time

Water/Alcohol Injection DIY Page
There ya go... it explains what it does and it is VERY easy to build and beneficial to a turbo motor. Most people use them on nonintercooled motors but I think it would work just as good on an intercooled setup

Yeah alki/water injection on an intercooled system has to be after the intercooler to prevent condensation. That means you'll need a fuel pump, regulator, etc. That's next on my list after I relocate my battery. I'm just running out of space under my hood.

I've used this system and so far I've hit 18-19 psi. By redline, however, it drops down to about 13. The reason for this IMO is either:

A. Turbo is too small (although my T3 did the same thing)
B. Crappy stock bypass is leaking.

Does anyone with an aftermarket BOV have this problem?

Its cause the turbos too small, i dont see why your T3 would have did that. Mine boost to 14psi and stays there solid. my stock turbo use to hit 16psi then drop to about 14-15psi

Well for one my T3 wasn't much bigger than the stocker. I'm trying to get ahold of a .63/60 right now.

You also have an aftermarker BOV, am I correct?

I had a friend do this same mod on a dsm, except he used a thermal cooler, the kind you carry your drinks into to keep them cool! he plumbed fittings in the cooler, and then put ice and water in it, then he would spray his intercooler before he made a pass at the drag strip! I could see how this could benefit! almost the same concept as the NOS intercooler purges!

very cool Brandon! I have a couple questions & comments... 1st of all, I don't understand why you didn't just tap into you're existing washer bottle. It would have warned you when you were running low. Did you consider using an adjustable thermostat to trigger it? Do you have an override switch to manually start the sprayer? Is is constant or intermittent? Couldn't you use an alcohol/water mixture to improve evaporation & cooling?

Okay, I think that's enough questions. This mod was on my "to-do" list (could you tell by my questions?) but I'm glad we all have an opportunity to learn from you're experinces with it.

Thanks!

I think as the BPV gets older, it tends to leak at a lower boost. Especially if you have run high boost. I have problems holding over 11 psi, but mine also has 180k on it so that's understandable. I just need to find a DSM bypass from the junkyards. Havent seen ANY so far...

Also, I do not have a manual switch hooked up to it yet. Me and a buddy threw the setup together right before I went out street racing the other nite (I know I know... tsk tsk)
As for the thermostat, what exactly do you mean? Like something hooked up to the intake temp?
Right now it only comes on when I boost over 11 psi, and stays on until I shift or let off the gas. Then if I go over 11 psi again, it will come back on.

For me, I wanted to leave my stock washer tank alone so I just found this small tank to use instead. I didn't want to deal with the hassles of getting to the stock washer reservoir, much less tapping it for a pump etc.

I do plan to put in alki/water as soon as I get the chance to go buy some. When I put it together I just threw a few ice cubes in there.

Also, anyone questioning the tank size. It's about 1 quart but so far has lasted me enough boosted runs to equate to like 5-10 1/4 mile runs... and it still has about 1/4 of the tank left. I'm thinking about adding another jet or 2 to the system.

The jets are just normal windshield washer jets, so they each have 2 small streams. I can bend the brackets to whatever direction I want. Right now one sprays on the top and one on the bottom.

Well I added water/akly injection to my car as well and it made a good difference. Normal driving in the heat was pushing my intake temps at idel to over 122F. And an avagerage of 105F+ intake temps when driving. (mind you out side temps are around 90-100F)

With the akly/water system in place the temps droped down to the low 80s high 70s. In much cooler night air avergave temp was around 67F. The car felt a little more reposnive and differntly pulled harder in the top end.

My system is a little more advanced than Rebels and its akly/water injection. I have the edelbrock vara/jection kit that came out in the mid 90s. Its got an adjustiable pressure switch, water level monitor and a bar that moves to show how much water the engine is using. Its a really nice system that was diconiduted a long time ago. I'll get pics up soon.

rebel2k4, try www.dsmtrader.com for the 1G BOV...there are plenty of people selling them. Probably will pay more than what the yards would charge, but at least there is a source if you aren't able to find any near you!

I have the stock BPV converted into a BOV using the brady valve, My boost drops off as the RPM's increases at anything over 10psi's its such a pain and I hope its just my BPV and not a boost leak somwhere else.
IMHO the stock BPV's are crappy and even at stock boost levels I think this cheap valve would begin to leak as the years go by, I can't wait to get a DSM BOV or some other BOV that can hold good boost levels.

Methman

PS: My boost stock was 10psi's so I think that the BPV may have been leaking before I even turned the boost up to 13psi's. since it was running such a high boost for stock..and god knows how old that BPV is, if not origonal.

Slightly vearing off topic, but I have no problems with my turbo hitting 19-20psi on a cold night, and it can sustain it for as long as I want, 'cept I'm hitting 200km/hr.... My ECU is tuned for higher boosts though, but still I have no probs at all, pulls hard and doesn't drop at all.

I'm wondering whats different with my car.... Anyway, on the topic on by-pass valves, mine leaked like a incontinent 90yr ex-porn star, but my new BOV works like a charm :)

hmmm...could have somthing to do with sea level's how high or how low are you.
