no...F7 should take it
I ride with my friend and raced him a couple of times, his is a 2000 MachZ no studs. Both times I raced him I was not studded and pulled away pretty good. Both times were rolling starts. I'm studded now and tried to screw with him the last time out but he would not take, I'll try again this weekend
I've ridden the Z(his) and I feel it won't beat the F7 and I'm not just saying that because I own one, I could give a shit less what sled is faster than mine.
He knows now not to screw with my sled though....He doesn't say much about my sled but when people ask him how mine goes you can tell by his reaction that he knows it screws.

To be honest, the Mach Z has a terrible track for hooking up on anything less than hardpacked snow. The F7 track hooks up VERY well which is why you see all of the complaints about ski lift. If the Mach Z can start at a 30mph roll on to help even out the traction, it should easily beat the F7. But, from a dead stop, the track will not allow the Mach to jump out of the hole. Skidoo should offer a 1.25 or 1.5 inch track on the Mach Z and then it would hook! But the F7 is still very fast for a 700 twin.

F7 vs SRX.....
My F7 is stock, 136 studs.....the SRX is stock, 192 studs......from a rolling start of around 30 mph the 2 sleds were dead even.....I don't think either sled pulled even 6" on the other.....all the way up to 90-95mph...when we ran out of meadow. My buddy and I swapped sleds......and tried the same thing......the SRX definately had the traction advantage on me....he spun much less.....the F7 is VERY fast.....with a few more studs....(170), I believe I'd pull on the SRX

well it didn't......twice infact.
Both times we raced we ran out of room, could nudge 100 and that’s it. Will it beat the F7 at flat out top end?...probably but how far ahead but will the F7 already be.
For shear acceleration at all speed below 100…F7 without a doubt in my mind.
Don’t get me wrong though about the MachZ…it’s a very fast sled and looks pretty cool too. I’d own one

I ran my stock F7 against a stock Mach Z 4 or 5 times the other day out to a half mile from a dead stop on hard packed snow on a lake, was not even close, I had him by about 10 sled lenghs. I'm not sure if he was gaining or not, I was running 106 when I let off. I was really surprised I thought he would be much closer to me. Maybe running a mile or two he would have been closer.
You obviously haven't got a clue.
After 50mph, the big torquey 800 triple will pull away from the smaller 138hp twin.
Either you guys are racing Mach's that have had no setup done, or the riders weight is close to 300lb without gear.
In 1000', the Mach can reach 100mph on grass. The F7 hits 90-95mph.
10.0 ET's for the F7
9.8 ET's for the Mach.
Yes the F7 is a bullet for a 700 twin, but it's just not in the same league as the mighty big triples. Sorry.

That must be a poor running f7 if it is only hitting 90-95 in 1000ft!!!My f7 carb hit's 92-94 in 660ft and hit's 102-104 in 1000ft....1800ft i hit 110 on the gun.If ur speedo is showing 100 on the mach z take of 10 mph and u will be in the ball park.

And why would it not hit 100 on grass???Get a grip on life....the mach was fast in it's day...same as the f7 will be over shodow by something in a couple of year's..but right now there is nothing beating them in 1000ft...the day my sled went 110 on the gun i was the second fastest there..the only thing faster was a 03 xcr 800 and he went 111 and he had alot more work done then me!!!If u can get the f7 to come out of the hole hooking hard..hardley anything is going to catch u..sure your sled might be faster after 2000ft but how often do u run that long???and u will have to do alot of cathing up to be ahead after 2000ft.If u think your sled is so fast go to a local rader run and see how fast u can go and stop through number's around some other sled ran...u might get a big surprise on how slow u are really going if u are going by your speedo!!!Oh ya the distance i went to get the 110 on the gun was about 1800ft and it showed 111 on the speedo!!!
I help setup our local radar runs this year.
1000' plowed ice
About 4 stock F7's ran.
mph ranged from 96-103 on this particular day. 25*F ambient temp.
2 STOCK CK3 Mach Z's with 192 trail studs went 105-106 respectively. One of them was mine. a friends ZR900 went 97mph(he is 220lbs). He put his sister on it(120lbs), and it went 101, with to trackspin.
You guys are not invincicble like most of you think. Thw big triples with traction are still faster to 1000', face it. Like I said, the F7 is fast, but its still a 700cc 140hp machine, not a blazing torque monster triple with over 150+HP.
Can't we all just get along? :dunno:

·Alright, thinking about this and doing some math, it comes out to the 2000 Mach Z ( 572 lbs DRY ), a 2000 ZRT 800 ( 561 lbs DRY ), a 2004 ZR 900 ( 506 lbs DRY ) and an 2004 F7 EFI ( 460 lbs DRY ). Mach Z 150hp, ZRT 800 150hp, ZR 900 150hp, 2004 F7 EFI 140hp ... and with these weights it comes out to:
1. 2004 F7 EFI... has 1hp for every 3.29 pounds
2. 2004 ZR 900... has 1hp for every 3.37 pounds
3. 2000 ZRT 800... has 1hp for every 3.74 pounds
4. 2000 Mach Z 800... has 1hp for every 3.81 pounds
according to the weight to horsepower ratio it is a mathematical certainty that with the identical conditions and weight of driver, a bone stock machine, the F7 is the fastest of the bunch, it 100 pounds lighter then the ZRT and Mach, and only produces 10hp less, but yes the F7 and ZR900 are both twins, twins will take the hole shot, but tripples are known for less torque and more top end, I watched several drag races between a 1998 Mach 1 700, 2002 ZR800, 2004 F6 EFI, 2001 XCSP 600, and the ZR 800 would kill everything mid lake, but the Mach 1 would be in second and easily pull by the ZR 800. so mathematically the statistics speak for themselves, now you have to figure in the hooking up, the aerodynamics (who can get lower, and put more weight to the track ), but if I were to be asked without doing the math I would say the Mach Z, an 800 tripple, same with the ZRT 800, they are some nasty machines, I am still in dilemma, but I can fight the facts. :dunno:

a well set up F7 on grass with the box reprogramed will do about 83mph in-
500' drags thats a fact. i've seen it lots of times. on the ice in 1000' it will do-
111mph to 114mph depending on who set it up, i've seen this lots of times.
both sleds in the right hands are deadly. the F7 is so much lighter. :imo:

:m2c: The less weight the sled weighs and the more power it creates, got to be a sure winner. I think we call these sleds firecats. Oh Yeah, thats right they are in fact a firecat. And for those of us who like to spend a little more money, we get even more power. As well as the smaller people, myself included, who can be compared to as a gnat on a horses a$$. An in all the firecat has got the power and light weight to pull ahead of the competition. :imo:
