upsides? More boost, colder intake temps, higher timing, less(if any) knock...check out some of the stickies/search

downsides? You'll get addicted lol

Btw, do you have a wideband?

Pro's

Youll be able to turn your boost up, Im at 23psi and still rich.
Youll be able to turn up your timing as well
Knock, never happenes

Con's
Youll find new boost leaks from the increased boost
Its addicting
Buying 5 bottles of windshield wiper fluid in preperation for a race weekend, will get you flagged as a suspected meth head
First and Second gear traction

I agree with all this

I buy 5 gallons like once every 2 months, costs me about $30. Mix that 50/50 so 10 gallons really...lasts me a while.

Looks like you have nothing to control fuel with, SAFC, DSP, etc. So in this situation you'd be working backwards.

nice!! i got a blown transmission right now lol but i think my next project is a meth kit and a safc!!

on the plus side i work at goodyear so i got all the high volume meth washer fluid i need lol

whats a good safc and meth kit??

morgantj13 · 09-23-2009, 12:26 AM

go with coolingmist for the meth kit...

kagekun · 09-23-2009, 09:28 AM

Good meth kit? Coolingmist.

cjh807 · 09-23-2009, 09:43 AM

safc???

kagekun · 09-23-2009, 10:21 AM

SAFC's cost about 50 to 100 dollars less then a DSP. I would just save and get the DSP because its infanatly better.

x2...

So if your car's are running lean like mine, a water/meth kit would richen it up without re-tuning? That sounds just about perfect to me!

kagekun · 09-23-2009, 03:50 PM

Without getting into specifics, yes. I havent tuned mine to the edge of meth injection, but I increased my boost and timing and Im still rich.

Im only using a map clamp right now to pull fuel. I pulled SO much fuel that the pcm freaked out and thought my map sensor was bad. At that point I was still rich.

DSP is the next purchase to get everything running.

are you stock turbo, and if so what psi you at? Also, are you using 100% meth?

Just curious cause im stock turbo, and just got my meth kit...but im probly gonna run a 50/50 mix.

kagekun · 09-24-2009, 09:08 AM

Stock turbo, lowered boost to 20psi to check something, I was at 23.

Im using Splash -30 De-Icer Windshield wiper fluied, Which comes out aroung 62/38 water to meth. (http://www.hardwarestore.com/media/msds/256131.pdf)

Once I use it up Im going to goto a 50/50 mix using Yellow Heet

Adionik · 09-24-2009, 02:12 PM

If the windshield works for you, fuck it, i'd stay with that. Only increase the meth mix if you start to see KR.
