Water Meth or HPFP???

[jtbizzy]

I'm debating between possibly going with a MAF based Water/Meth kit or the High Pressure Fuel Pump kit upgrade. Going W/M would be the safer of the two considering so many horror stories associated with the HPFP kits failing. On the other hand the HPFP kit offers better performance overall. Does anyone on here with a MKV 2.0t have W/M and if so could you chime in with some pros or cons of it. I've read where the W/M kits add around 15-20 HP where as the HPFP increases the torque by quite a bit. I know a few on here have the HPFP kits and have been pretty happy with them so far.

water meth. you just missed a great deal from sweaty. he gives a pretty good handjob too. :wanker:

IDK if you already made a decision on this cause im a few months late. I have both installed on my car. Did the HPFP first. Used a KMD pump and Revo tune. It was a definately noticeable change in power. Water meth on the other hand is probably going to suit you better that it has for me due to the higher heat and humidity on your coast. The only power i have been able to tell noticeably from using water meth has been by ramping up the timing maps on my revo tune.

Hope this helps you some Bizzy

Thanks for the input... I think I'm probably going to go with W/M kit when I get my $$ right. Does anyone know what the best brand is for the MKV's? I'm looking for something with as little maintenance as possible. I don't have time to be checking it every other day and having the car constantly in the shop because of it. Is there a kit out there that is pretty low in maintenance except for the fact that I have to refill the tank?

all the kits are low maintenance. there is much more to be had by using water/meth. IATs are lowered DRASTICALLY, and the octane on average when used with 93oct is boosted around 15pts so that puts you around 108oct. Both these factors combine allow you to run substantially more ignition timing and/or boost than before which should and will result in more than just a 15~20hp gain.

damn q. all that talk makes me want to install mine this weekend!!

damn q. all that talk makes me want to install mine this weekend!!well i should know i sell the shit...i work for USRT. i should have my own next week....its has been proven that w/m in terms of octane can equal c16:lil_yellow_devil:

[pinky]

where is the data for that? just curious.

[pinky]

truthfully, all that tells me is that with 93 plus meth and c16 you get the same power for the same boost and timing..

i guess the only way to know for sure would be to push an engine to detonation on both, something i doubt anyone really wants to do.

can i use 13:1 n/a with methanol and 93 octane?

can i use 13:1 n/a with methanol and 93 octane?thats pretty much what you aim for n/a anyway. and what that should tell you is you're able to push the same timing without detonation using either method. if you read in there no more power was gained from upping the timing from 23* to 26*. I wonder if they have another study with more boost somewhere that blower was at its limit already.

[pinky]

sorry, 13:1 compression ratio

it will work with c16, but since they are equivalent it would work 93 octane with meth?

[Q_dubz]

sorry, 13:1 compression ratiooohhhh lol...yea absolutely...i plan on building an n/a car for just that!

I vote water meth on this debate but....... ..... I do not see anywhere near the gains from timing increase in the 2.0t that you get in port injected motors. The other issue is if the car is tuned for water meth or not. I have run a ton of meth and it will not suppress knock like race fuel on my car. I ran 27 degrees of timing up top with 23psi on 111 octane no problem but with 93 and meth it would only take around 21-22 degrees. Even with a nozzle in each of my 6 intake runners. I still think it is a mod with good potential but without tuning the entire ecu for it you cannot see all the gains. With a regularly tuned ecu you end up with a too rich mixture to see the gains.
If you tune it lean enough you had better hope the solenoid doesn't fail.....like 3 did for me.
Also in this case JTbizzy has an upgraded IC so heat soak isn't as much of an issue. He also has a stock turbo so he isn't going to push any more boost or he will need a new turbo soon.

And I leave you with Corky Bell's take on it. Hmmmmm.....
"The water injector is not a very interesting device. It has little place in a properly conceived turbo system......Rule: A water injector on a turbo car is a poor-excuse band-aid for not doing the job correctly the first time"
Corky Bell, Maximum boost.

[Q_dubz]

interesting Evan...very interesting indeed. Did you try different mixtures? More water = higher octane.

[evan@absolute]

I tried more or less total volume injected but never really varied from 50/50 water meth. I am 100% that it is better then without I just think race fuel is better if you are looking for race fuel power. I felt like water meth on 93 gave me what I would imagine a 97 or 98 oct would do.
I will say that the nitroboost shit is crazy. I never dynoed with it and never had the balls to run it down the dragstrip but the shit was crazy on the street(or should I say closed course;))
