can a stock 1.8t handle stage 2 boost controller from snow performance?

you will run super rich and not benefit, it would be a waste of time and money

I never wanted to start a thread like this, but I have been curious about the Snow Performance Stg 2 myself. I have the Ctapp flahsed k03s (I will stay with them all the way to BAT), so I would get a second file for the meth kit. Not to thread jack, but this is info I would need for consideration. I was thinking about getting the Meth kit instead of a FMIC. And winter time is coming, so I would get it when the hot weather settles back in. What are the pros and cons of a stg 2 meth kit with CTapp tune on stock turbo as compared to getting an fmic? The only pro I have is it can do the duty of an fmic on a stock flashed turbo and I will be able to keep it untill I have a BAT (so, no need to purchase later on). Advice is always appreciated. Thanks!

*side note* Yes, I already searched and there was not many threads on it. Just about installation and the adaptor for the intake manifold instead of plugging into the TIP. And also how the throttle bodies can get damaged, that is why the post throttle body IM adaptor is what I would run with.

I wouldn't use meth as a replacement for an intercooler. I would really consider doing both especially if you are running a larger turbo. Meth is nice because you can use it to prevent detonation as well as lower intake temps. I personally use water/meth to lower my intake temps a bit more than just my front mount and also to prevent detonation but I don't rely on it because I don't have the proper fail safes installed as of yet (SafeBoost module mainly). If you do have the proper measures going in terms of fail safes then tuning for it is a great idea... but get a FMIC on top of the meth because they are cheap and almost never fail.

But as for the other (original) question from a4mafia... why on earth would you want meth for a stock car? It might be a good idea for you to do some background research on google regarding the idea of spraying meth/water.

without going into too much detail...

I'm running in my 100octane program on 93octane fuel with zero timing correction or knock in just about any condition....

APR Stage 1 ECU with Test Pipe on K03. I'd say it's worth the expense.

I made the move primarily for my autocross habits. It's a great way to instantly reduce IAT's after the car sits for an hour or so between runs. I will say though...it's quite nice being able to drive everyday in the 100 Octane tune on 93. Using the 4.5L washer fluid reservoir that's in the B5, I usually go 3 weeks before filling up with another batch of 50/50 water-methanol.

As far as the AFR comment goes: at WOT the ECU looks for a specified AFR...so unless you're running a super aggressive water/meth setup...you'll be fine and the ECU will adjust fuel as needed. I haven't seen/heard anything against that.

Damn dude, do you ever stay out of boost?

Basically, yes. The car can handle it. There's a handful of ways to go about it, you can start with a basic boost switch (2D mapping) or go ape shit and do some progressive and rpm dependent 3D mapping.

After doing the research I think I'll wait and spring the big bucks on the Labonte Motorsports ISG-S3 Kit.

Lol me next! Where do i start?

Start by buying my Snow Stage 2 MAF control brain so I can swap it out for a more advanced (progressive) unit :-)

[a4mafia]

Why would I do this on a stock car? Let's think for a minute. More power maybe?

[Poopie]

No real gains, but won't really hurt you either. Maxspeed had a stage 1 devils own kit on his lemmi tweaked 2000 and from when hes posted, it was pretty quick.

[Seerlah]

So, it is not really a good investment unless you have a bigger turbo? Then why is it people get the flashed/chipped ECUs for thier stock turbo w/race file if there will be no real substantial gains? Or is it that people run real race fuel (100 octane)vs 93+meth? But will that really make a difference? There has to be another benefit other than lowering intake temps. How much more hp does one conjecture the meth kit will grant on a stock turbo (yes, I know one will notice substantial gains on bigger turbo applications)? 15? 10?

Pardon all the inquiries. Thanks!

[GetBoosted84]

I think what people (myself included) are trying to say is that meth/water injection is not worth it for a stock car. A car which you are tweaking with lemmiwinks and have a chip or k04 can benefit from meth/water. Not really on a stock car though... although like poopie said, it won't hurt it either.

I used meth a few times to run the race program from my hammer file when I was k04'd and my timing was looking good (the giac race program is built for 104 octane IIRC) but I only did it a few times and I was watching my logs like a hawk to make sure all was well.

I would recommend that if you are planning to use it as a replacement for race fuel on a race fuel program that you make sure you have a fail safe in the setup to avoid possible engine damage.

[Poopie]

on a standard pump tune you won't see much gains.


Running meth on my ctapp 93 program on a gt3071r did not gain me anything noticable.

[GetBoosted84]

Poopie, you planning to go to the track on Friday if Ian is going?

[Poopie]

probably not. I'm crazy busy running around these days

[GetBoosted84]

I hear ya. We gotta get your car down the track one of these days (after the gt30r) :-)

[a4mafia]

well see...im going big turbo which is what i was wondering. oh well i guess i will just forget about it for now

[djwimbo]

In theory adding W/M inj to any file that is not tuned for it, will not make any significant gains (or any at all). If you have your setup tuned for the use of W/M then it's possible to make more power.

No, I can't promise that it will make you more power. I can say that your intake manifold will be noticeably cleaner after using W/M inj though.
