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.

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
