I would also like some opinions on this same kit as I am just about to buy one! Can't decide between this or the Coolingmist GS PRO.

They both have plusses and minuses, but the Snow Performance controller just looks so much better :P

Is anyone else using one?

I've got my settings at 30-65 IDC and 8-14 psi and was wondering what others were using?

Also has anyone tried passing emissions with a WMI kit fitted?

I would imagine that it would actually give you a better result with an emissions test??

mine is an older kit but its set to start at 8 and flat out at 20. it was also fully operational when i passed the nsw emissions testing.

you will likely find the car never sees 8 Psi while they are testing.

Guys what size tanks are you running and how long do they last?

I'm about to order a stage 3 kit and you can get a option for a bigger tank just dunno wether it's necessary.

Sorry for the hijack.

i am running the large snow performance tank, 9.5L capacity.

How long a tank lasts? months, too long to remember fill dates.

I have the 2.8 Ltre tank and for normal highway miles I can do 2000km on a long weekend and am lucky to use 1/2 a litre.

I am usually sitting on 100-120km/h with overtaking and accelerating etc, the normal stuff. So unless you are racing all the time the small tank is heaps. I didn't need 10 litres sloshing around when I couldn't use it.

Have a look at how I mounted mine in the ash tray recess:

No cutting or anything, pretty much a straight fit with some small brackets to hold it there.

Pretty good read which covers installation and results.

It's for a BMW but still worth looking over

the last snow WMI kit we had through was on a late model BMW M5.... 304rwkw without 348rwkw with it turned on and setup via injector duty (no ecu tune changes) cant complain.

Trent would it still be considered "unsafe" on an unopened engine (25) over 300+ kw using WMI? From my limited understanding it has similar effect in regards to knock and temps etc to e85.

I have just installed a 2835 pro s which as we all know will net me around 280 but I'm a little worried about pushing much more out of the stock bottom end.

What sort of gains would you expect on an rb25 with a ~250kw turbo that has maxed its capabilities out (eg hot intake air), would it let you run much more ignition timing to make a difference?

Rolls I'd think that you would get an extra 30rwkw out of it.

On the forums they say that 93 octane with 50/50 wmi is 116 octane. Its not what I say, but is quoted on the forums again and again.

So what would your motor do with a cooler combustion chamber and 116 octane fuel?

I remember seeing a really good graphical plot on the differences between no wmi, 50/50 wmi and 100% meth. I'll see if I can find it, but it was a while ago.

In the meantime is you look at:

http://www.snowperformance.net/forum/

and

http://www.aquamist.co.uk/vbulletin/index.php

you will get a good idea of the benefits. There are others as well, but these pretty much cover it all.

Do you get the same benefits combining water/meth with E85 as you do with 98 octane? Or is there sort of an octane limit where the increased knock resistance doesn't help you extract any more power?

Thanks for the answers anyway, I might look into it in the future.

      GTR R34 Limp Mode

      By GTSBoy · Posted

      Has equal chance of cleaning an AFM and f**king an AFM. I think you can work out what happened. When the Hitachi ECU sees the AFM die and goes into the associated limp mode, then it will start and run just fine, because it ignores the AFM and just runs on idle maps that will do what it needs to get it going. But there is no proper load signal, so that's about all it can do. My suggestion? If you don't want to go full aftermaket ECU, then get some R35 GTR AFM cards and some housings to put them in, in the stock location, and Nistune the ECU. Better to do a good upgrade than just replace shitty 40 year old tech with the same 40 year old tech.

      GTR R34 Limp Mode

      By steven7270 · Posted

      So my car was recently having trouble starting on initial crank, I would need to feather the gas for it to start up but besides that it would start and run fine. So I clicked the idle air control valve (with throttle body cleaner) and cleaned the MAF sensors (with MAF cleaner). The start up issue was fixed and now the car turns over without the assist of the throttle, but the car is in limp mode and wont rev past 2.5k RPM. From what I understand the IACV would not put the car in limp mode, so I am to believe it is the MAF sensors, but it was running fine before and now I cant get it out of limp mode. I cleaned the MAF made sure the o rings were seated properly. Made sure the cables were plugged in properly, the cables also both read the same voltage. Does anybody know why this is or what could be causing this or how to get it out of limp mode?

      Thanks. Yeah I realised that there's no way I'd be able to cover the holes with the filler, it would just fall through. Thanks again @GTSBoy!

      That was the reason I asked. If you were going to be fully bodge spec, then that type of filler is the extreme bodge way to fill a large gap. But seeing as you're going to use glass sheet, I would only use that fibre reinforced filler if there are places that need a "bit more" after you've finished laying in the sheet. Which, ideally, you wouldn't. You might use a blob of it underneath the sheet, if you need to provide some support from under to keep the level of your sheet repair up as high as it needs to be, to minimise the amount of filler you need on top. Even though you're going bodge spec here, using glass instead of metal, the same rules apply wrt not having half inch deep filler on the top of the repair. Thick filler always ends up shitting the bed earlier than thin filler.
