Cliff,

This was already discussed on your other "sponsored" thread and you chose to ignore it rather than respond. This was my post.....also backed up by Bluemax and others.


MaximumSled weighed an 07 Mach Z. Wet weight including a FULL tank of fuel was 596 lbs. Without the fuel it weighed 529.6 lbs. This sled did not have electric start.

Where are you coming up with 650 lbs?


Relax Driggs........Let's have some fun with this once and for all, I'm curious as well......My buddy Mark has a 'totally stock 07 MachZ' that he'll hopefully allow us to use as a test mule. When it's convenient, I'll take my (4) scales over, fill his sled up to the proper wet weight and check it. As you know, my race 2007 MachZ was 579 lbs with 1 gal of fuel in the cell, let's see what his is........I'm going to go out on a big limb here and say 600+ lbs!!!! I'll report back ASAP.

Hi boys.........While we wait for my buddy Mark G. to get home for a studded, full of gas, stock 2007 MachZ weigh in on May 24th, here is a note from Mark B. at American Snowmobiler about there own 'wet' weigh in with a 2007 Mach.

Cliff,

Unfortunately, we had that demo sled one year before we started keeping detailed wet weights. However, the 2007 Renegade X 1000 SDI (same motor, just a little longer sled) weighted in at 658 totally wet and without studs. Just for reference. You can probably come pretty close to guessing the wet weight of the Mach by extrapolating how much more weight a 136 is than a 121.

Amazing what these things really weigh and where the weight is. The Yamaha Apex was 706 lbs no studs as per AmSnow!!!

P.S. - Get your bikes out yet?

Loved my old Yamaha sled but they are pigs - way too heavy and the handling is not good.

That's pretty much what we've seen on the gun - 168klm (104mph) in 2000ft is all you'll get from a stock 800 E-tec, and that's actually good. In a 1/4 mile, most struggle to hit 100mph.

Really?.... I just pulled my notes from when we ran the Gravenhurst track the weekend after the NBSSR races back in March and were topping out our 2011's ETEC where from 111 to 113 on the gun all day long. It was -20 lightly snow packed but because of strong head and cross winds gusts we got pushed off to the side of the track many times. Here are some of the top speeds I recorded on the gun measured 2000ft that were GPS confirmed btw...we would have tried for more but ran out of room to slow down before the end of the track...

2012 Renagade 800 X - Bone stock - 108 mph
2011 Apex Clutched - 114 mph
2012 Polaris Rush - 108 mph
2002 Yamaha SRX - 112 mph
2003 Yamaha RX1 - 108 mph
2011 XRS 800 ETEC Clutched - 113 mph
2008 Red Apex- 111 mph
2003 Arctic Cat F7 Not stock 114mph
2011 800 Etec X - 112 mph
2010 Blue Apex 112 mph
2011 800 X Etec Clutched - 113 mph (mine)

Will do....we have 5 Etec 8's in our group that are set up well and run strong. I read your posts so next year Im going to try that Straightline 30 shot and few other mods....sounds win win for some extra especially for those warm days when mine runs like a dog. What is your best guess for top end increase with the NOS?

IMO the biggest problem with the E-tec is also it's greatest asset - the combo of a high compression and ignition 'advanced' motor. This set-up requires 'great octane' all the time (premium 94 whenever possible0 or the motor will redcue it's own timing and the power. Use the good stuff, I run VP Fuels C14 Plus 115 octane all the time, juice or not, and I don't feel any lose of power, no matter what the temp your rev's will stay right where they should be all day long - 7900rpm-8000rpm. If I'm forced to run "edit for bad language" 'Up Nord' gas in my 800, I'm off the juice imediately and I loose 200 rpm within minutes, it's like clock work. The detonation sensor is very sensitive and it retards the timing at the slightest of readings. Change your fuel back to the good stuff and all is fine within minutes on mine.
Jason's Straightline Performance n2o kit took me you from 103mph in a 1/4 mile on ice, to 113mph in the same distance on the NBSSR gun on pump gas. The 60 shot gave me 117mph on a rough track on C14+ race fuel - I'm convinced it'll go 120mph in a 1/4 mile next season, just needed a helix change.
Cheers,
Cliff

I totally agree on the fuel thing as now a days I doubt 91 is even what they say it is. I have never ran anymore than 94 with half a can of octane boost but with colder temps the sled runs real hard and puts up big numbers run after run when I do. When its warmer out say 0 to -5 with the same clutching/gearing set up my top end MPH is down by 5-7 mph running...so Im thinking these things run on the rich side when warm out with the mapping as all the other Etec 8's in our group run the same down on top end mph but RPMs are always at 8000 + - 100 and very consistant.

I will look into runinng that 115 octane in a 50/50 split with 94 for those test n tune play days on the lake. As for the NOS can wait to see what this "happy button" will do for my top end mph as my best was 115 on my GPS I pulled off a few times last winter!

I wouldn't waste your money running a race fuel mix unless you're using a 60 shot (and then it's not a mix, it's straight C14+) it's unecessary. Just make sure you fill-up with the good stuff before you take off.
