Does anyone know if the snow button does damage to the car if you have it on for a fair while??

I know it takes off in second, would this be a problem after a while??

Before you all scoff, if you are just cruising around, try it for a while and you can get used to it.

The fuel economy improves heaps and the car pulls a lot lower revs, and when you need to go you can just flick the switch!

my understanding of engine load is that it is greatest at low rpm in high gears

this means consistent taking off in second gear will put a huge amount of stress/load on the transmission / engine leading to premature drivetrain wear

its up to you but when you think about it, if it was the best and easiest way to do things then it wouldn't be a special button, it would just be the way it was made in the first place. and this is not the case.

The thing is, the primary function of that switch is to take off with less tractive effort in low grip conditions. The button's existence isn't about "the easiest and best way to do things" all the time, its about the easiest and best way to do things in a specific situation.

Even if high load at low RPM caused no extra stress on the drivetrain/powertrain, the button would still be there as you don't always want to take off in second gear with a less sensitive electronic throttle.

It'd be like if someone asked if turning up the stereo to a certain point would damage the speakers, and then replying that if the speakers were meant to go that loud then there wouldn't be a volume knob then the stereo would just be made to play that loud in the first place.

I'd agree that it probably does more harm than good, though. Taking off in second does load up the driveline and cause extra wear, and that is a bad thing. The few bucks you save in fuel won't offset the cost of reconditioning your engine because you've made it lug for a lot of its shortened life. Its not like the V35 is a tow vehicle, and first gear is just there to provide more tractive effort while pulling a trailer.

    • Nah its a server spammer thing  Although, now that I manually approve all the accounts I can probably loosen up some of the restrictions.  
    • Thread bump, again! Although, no bad news this time. Posting for the sake of possible root cause. Basically, I rebuilt it (mostly stock), installed Haltech + sensors, had it running fine on new ECU.  Still not really understanding why it cracked pistons last time. Got to tuners, and while checking timing, noticed +-10deg of timing scatter while revving. Changed CAS, and it was rock solid. While not definitive, can't imagine seeing 20+ psi with that amount of scatter would be a good thing. Also glad I found something.   Bit more of a run down; Carried out a stock rebuild, a set of stock pistons, out of a spare bottom end. Everything stock apart from head studs and oil restrictors. (so I can pretend I didn't let the Nissan out, ha.) Armed with the measuring gear and FSM, set about doing overhaul. Oil restrictors as per oil control thread for a RB25, stock oil pump, drifting. Head drain/vent from rear of head, to passenger side of sump above oil level. Two dash 10 vent lines from drivers side of sump (unused atm) Hi octane style cam cover breather kit Splash covers over last 2 cam caps. Both breather lines from cam covers to vented to atmosphere catch can, not plumbed back into sump (wanted to see what it was actually breathing). Got it run in (did about a 1000km) no to low boost scenario, As I had questions over old ECU setup. Installed haltech +sensors for flex Retune on E85 (finding CAS Issue along the way), made 300rwkw at 20psi, out of wastegate. Did a drift day the next day (yes, it was a big weekend!) and was checking catch can throughout the day, ZERO blowby. I mean nothing. Lines from cam covers are not even wet. Done a bunch of street driving, spirited and catch can is still dry. Early days I guess, but pretty happy so far. Also now run 10w60, up from the 10w40 that I used to run. Oil pressure is significantly better, especially when hot (as you would expect)      
    • Thanks buddy. I thought it was a server storage thing. 馃ぃ
    • Perfect! Thanks for this, both look like great options!
