water & meth injection results

More like tomorrow

Well good luck to you sir. I don't plan on attending.

Cool. I just got my Coolingmist 150psi kit installed and will soon have some results myself with three different flavors of Wal-Mart WW fluid

BTW, doing the math, my OEM 3qt WW reservoir should last 9.4 minutes (563 secs) of spraying my M4 injectors (4.8gph @ 150psi).

As I don't intend to activate them until ~17psi (75% of total 23psi), I figure should last some time

Nice, that's the kit I have. I went with the M5 injector and it wasn't really enough for me, I have an M7 now and I'm still considering going a little larger. The M7 definitely helped over the M5. I'm running 100% alky though.

Der, I meant the Engine Runup 150psi Kit

Not sure how much it'll help me as I've a pretty efficient turbo/FMIC combo and run 23psi (45 lb-min) with no knock all the time with 11:1 AFRs and 16deg max timing on pump93

Good lord i need to take care of my boost leaks. I only hit 39-40 lbs/min at 22psi. Of course you've got a SMIM. Though i do have an extrude honed stocker on the way.

Wow, that's very good. On 91 pump I could only get away wtih about 19 psi, but after alky injection I've run as much as 26 psi with no knock with the same timing.

I also have the EngineRunup kit. I have dual injectors, one M2 placed before the intercooler to eliminate heat soak, and one M3 placed right after my BOV. My pump is placed where the rear seats used to be (I flat-topped my trunk with carpeted MDF for a two seat conversion), and is plumbed into the lowest point of the windsheld washer resivior. Unfortunately, this is on the passenger side of the car, so if I take a VERY hard right turn under boost, the pump may suck a little air. Doing this yesterday caused me to see the first signs of knock in quite a while.

I also run -20 fluid. I find I go through a gallon every 270 miles, roughly a tank of gas. If I can stay off the throttle, it lasts longer. Pressure switch is set for 7PSI, which keeps the combusion chamber nice and clean.

DSMLink is set for CE flash at 1 degree of knock retard.

Before the kit, I had to retard timing by up to six degrees at 16 PSI. Intercooler would heat soak after 1-2 hard pulls in third gear.

With the kit, I now run 20PSI of boost, full timing, no knock on my EIII16G with stock SMIC. I cannot heat soak the intercooler. Repeated pulls generate no knock. Beat on the car all day, no knock.

The car still wants more boost. Easily the best single mod I have ever done.

Matt.

Have you ever trie drunning meth/water instead of alky? I'm curious as i was thinking of trying to run denatured alcohol instead.

So maybe I'll turn it up to 30psi

No, but when this gallon of denatured alky runs out I'm buying a 5 gallon container of meth..I was thinking of going straight meth but I might try a 50/50 mix first.

Definately let me know how that turns out.

few days ago I had my throttle body off replacing shaft seals, and when I looked inside my intake manifold it was absolutely spotless, like it was steam cleaned... i should have took a picture, but i was pretty dirty and didnt feel like cleaning up just to get the camera.. I took the plugs out to check my pistons, and you can see the buildup on them is loosening, so i give it another 700 miles, and im sure they will be clean as well.

heres my final mod for the meth install;

Looks like someone won't need to refill for a while. Enjoy.

The farthest anyone would have to drive to get meth would be to your nearest walmart, they have the winter washer fluid, which contains 49% meth/ 49% water for only 1.99/ gal.

I'm planning on building my own kit using parts from Coolingmist, BE Cool, and Engine Runup. The kits they all sell dont seem to have the parts together in a kit that I want for my setup. I calculated the total cost for everything and it shouldnt cost me more than $200 for everything shipped.

 

[spyderturbo007]

Are you guys running dual nozzle or only a single?

Well, after hearing about a year's worth of positive feedback and actually getting some concrete knock, timing and boost numbers, I think I've found my next mod. It will have to wait until spring since I just put the Spyder in storage.

 

[90blacktsiawd]

I'm only running one nozzle.

 

[unclesam099]

When do you have your meth set to come on? How low is too low?

I ask because I'm having problems running too much timing as a result of a MAFT and low airflow numbers (creating the high timing).

Currently, it comes on at 8psi. I run 18-19psi. 100psi, M5 nozzle. I want to jack it up to 120psi and/or get an M10 nozzle.

I see knock around 8psi, so the meth doesn't help then. Could I run it on at 4 or 5psi or will I see problems with bogging down?

 

[90blacktsiawd]

How is it your having a problem with high timing? If your profiles up to date you are running stock injectors and even when you put those 550's in they arent big enough to really give you a huge problem in that area.

Are you sure you have the base timing set properly? Where you getting the knock before the meth install?

 

[unclesam099]

90blacktsiawd, I have a thread titled "Timing help needed" in this forum about my troubles.

I have set the base timing to 5*. I haven't updated my profile in awhile. I am seeing knock come on as the turbo is spooling at 2800 - 3000rpm (8psi or so). I did not look at the timing at idle once I pulled the jumper wire off of the timing ground pin, which I regret NOT doing and I will try to do that this weekend.

My problems went away with a few gallons of 100 in the tank, but I won't be using that for a daily driver seeing that it's $7.99/gal.

EDIT: Updated the profile, I think it's accurate now.

Because the 1g timing curve is extremely agressive. Which will limit your abilities with pump gas dramatically. 1g's go as much as 22deg, whereas 2g's max at 16deg. very large difference.

If your seeing knock at those boost levels, your tune is off. you are either trying to run to much timing or your a/f needs tuned a bit. I set my system to start spraying @ 11psi. Ive experienced knock downlow around the same boost levels as you. I had to retard timing & add some fuel, and it went away.

One nozzle is plenty. Most setups will do just fine with an M5 Nozzle.

 

[unclesam099]

Tom, I had the timing as low as 0 base and there was still knock. I have tried running really rich and running lean as boost comes on, but still nothing. I really believe that it is an octane problem and a knock sensor being old. So I may replace the knock sensor and go from there.

 

[exiletalon]

hey, what are the best kits for the cheapest amount, I am looking for the most simple efficient kit out there. I have TDO6-18g, 650cc. I am running 18psi without knock-any higher and I get some... I am looking to run as much boost as possible on 91oct, but stay relatively cheap- set to come on at 15psi.
Thanks guys.

 

[90blacktsiawd]

Any of the basics kits will work. But they do get much nicer and tuneable than the basic.
