Hmm no blown fuses here at 40 psi, stock fuel pump. Must be because of proper size injectors
Thank you I was curious about that so strange.When you get over approx. 20lbs of boost for a sustained period the stock fuse pops. Doesn't make a lot of sense as the fuel pressure doesn't rise with boost so the pump doesn't see more load but it seems to happen on all of them. They must be right on the limit of the fuse in stock form.
Yes data logging is great, how ever a lot of guys are set it and forget it.You can't data log their flash. Worthless if you can't data log it. Especially the big tunes.
It’s a touchy subject forsure. But In the performance game there is always going to be failures. If you are not wanting to take that risk you should leave your machine stock.pefi have nice things no doubt. I just worry those several stage 2R last that blew and they were left with blown motor.

Wow !!! Great results !! With stock gearing and drivers ?!For anyone wanting their Mach to run better, with the advise of a Rocker Dan ( thanks a ton!!!) I installed the 880 ramps and 44/38 helix while keeping the stock spring. Honestly can say that it feels like an entirely new sled! Pull so hard low-mid range it’s almost more than most people will need. Up top it never stops pulling and that feeling of hitting a wall on rail grades is no longer there. Little bit of background, my sled would hit 7700 every time and then drop back to 7600 and feel like ecu was pulling power. With the new combination it pulls 7900-8000 every time and hold rpm the way it should and no longer has the feeling that it’s pulling power. This was riding at about 20F. Sled now runs side by side with my buds thundercat from a slow roll, whoever gets the jump maintains the lead slightly. Can thank Dan enough, my Mach now feels like the sled that should have been delivered by brp.
I agree with you but it just seemed their was many all at once like it was tuning mistakes. I may be wrong but didn’t t hear of TD tunes blowing 1100t back in the day. I guess what I’m saying I want a tune but if it has 5 less hp so its safer I prefer that.It’s a touchy subject forsure. But In the performance game there is always going to be failures.

Tunes taking out motors happen more often than guys will admit. I know a few 900t motors that have gone down with just 16 psi tunes. That's why data logging and octane are so important. Get lazy once and that's all it takes.I agree with you but it just seemed their was many all at once like it was tuning mistakes.

The dream meter is set so you won’t get a speeding ticket. LolI did a quick 271 mile run yesterday on my 900r x. It was -30 c and the humidity was low. Finally hit 120 mph speedo (108 gps). It took about 1 mile to get there. It would go up to 105 then to 101, then up to 107 then down to 103. Then up to 114 down to 110 then 120 down to 116 all while holding it wot. Each time you could feel it stop and start accelerating. That's not clutching. Was at a constant 7700 rpm . Later in the day it was back to 7500 and 108 on the speedo. View attachment 1990785
The 108 GPS is an extremely rare occasion. 98% of the time it's 103 GPS. If it ran like it did on Saturday 100% of the time I would be extremely happy. With the cold temperatures it was better everywhere. Ran very similar to my tuned 900t except for top end, but I'm OK with 108.The dream meter is set so you won’t get a speeding ticket. Lol
Yours is running pretty good ,Hopefully BRP comes out with a new update to produce more top end speed.
Id keep the stock belt. I’ve had no issues with it on my mach. Need toadjust the belt deflection to about 1/8” from bottom of cogs to above sheaves.that helped with some low rpm lurching/grab.My mach ran 8000 ish plus or minus basically out of the box. 200 km on it running 8000 rpm it ran 186. 450 km on its running 180 at 7800. Today tried to change to a 531 belt and it's worse in better condition 7600 rpm but still 180. Hit 180 pretty easy then flat. Any thoughts? Or stop thinking about it till i put a few more km on?
What belt should I be using stock or 531?
