Does this little guy take out a 440 liquid cooled Rupp in 300'? I bet it would be a good one   Man, if the Merc could pull it off! It would be all over but the cryin'! And there already seems to be enough of that in another thread  |

Probably would kill it in the 300', but don't run one for over 500. ;D

In all seriousness, at the 500' mark the 440 should be far enough in front the Merc can't read the sno flap!

A dialed-in Merc 250 such as the one Romanowski races will run around a 7.25 ET in 500ft according to Paul. After 3 years of tuning I have finally run some mid-6.7s with my 440 Magnum this winter. It was challenging to crack the 7 second barrier the first season I worked on the Magnum. I do believe a dialed-in Merc 250 will give the average liquid Nitro/Magnum 440 a good race in 500ft on ice.

Looks to me by those numbers the 250 merc is going to beat the 440 magnum by 4 or 5 sled lengths in 500 ft.

I do believe a dialed-in Merc 250 will give the average liquid Nitro/Magnum 440 a good race in 500ft on ice. And in the original post I was talking 300. Let's show a little mercy to the sled that only has a bore the size of a silver dollar! Nope !! Hell I'd even race against this guy and bet money on it LOL... That says 440 on the tunnel?!? Despite the lack of a holeshot, I bet it runs down about any Xenoah. Be assured, my 250 comes of the line just slightly quicker then the one in that vid. |

Despite the lack of a holeshot, I bet it runs down about any Xenoah. Be assured, my 250 comes of the line just slightly quicker then the one in that vid. Not that it means anything, I bought the sled from Phil Barr. He did the mechanical restoration, engine work (Did I say engine work? I meant rebuild!), clutch and carbs.  All in good fun Eddie I was wondering when you were gonna spot that 440 decal , makes me feel good though that not "ALL" Mercs are immune to the bog, and after actually driving a couple of them, a 340 and 440, I expected a lot more ??, no doubt the You-Tube one needs tuning. You know I like the 1000' and 1320' runs myself. I seen a couple R.A.V.E. 250 super mod 'Doo's run at Beausejour, that gave me a new found respect for the small bore 250 motor.  But that's another story all together. |

sounds awfully boggy to me. Huh, must have a Xenoah in it  The Thunderbolt ignitions in the Merc can be ridiculously temperamental. That baby might need some new wiring on the stator or a new coil. Either that or it has a clutch for a wide belt on it and still running the 1 1/4" belt. |

BOGS suck whatever motor it might be !!! I was out playing around today with the new primary spring that I threw in it last year after racing was all over with. The ice that day was so crappy that all it did was spin but still it had better times than the old spring with less slippage. Now I need to harness the new found power !! The god damn thing is outta control now !!! You talk about squirrelly !!!!! Skis come off close to 3 feet and it is pulling to the left. The one time I had to get off the gas and on the brake. All I could see was sky. Now its snowing 2 inches per hour. In the morning its supposed to change to freezing rain then to completely rain. What ever happened to the cold Wisconsin winters with no snow ? I think that I figured out the pulling to the left issue. I did alot of measuring of the suspension tonight and changed 1 thing. So tomorrow it looks like I have to clean off the pond again tomorrow while I still can. You can take this snow and SHOVE IT !!!

Dale, my 250 merc times are 7.45 its dans 72 nitro with the 7.25 times and his nitro is a couple sled lengths faster in 500 feet. I clutched dans nitro, if it had the stock rupp clutch on it it would not even be close to the numbers the hex puts up. Dan's 72 nitro is probally the fastest stocker 72 nitro around. Numbers are just that, dale's timer will put up numbers ours will also, the bottom line is who crosses the finish line #1.
Like it or not, I race mercs because in stock form they have advantages over most the sleds they run up against. Go back to 1976 and merc had 653 wins in USSA oval racing, rupp had 13, the next closest manufacturer had 174 wins that year. This info can be found on page 52 in the April 1976 Snotrack racing yearbook.
The 440 merc in the you tube clip looks like a slug, I'll bet the clutch engagement is barely 4500rpm, it is probally some rookies sled who thinks he has the world by the tail, someone should video larry Spindlers 440 s/t stocker at waconia this year, you rupp nuts will see what a dialed in merc sno twister will perform like.
Back to the 250 vs 440 challenge, it's fair to say the mercs are a lot quicker than the 76 mags size for size, history has proven that back in the day and it still proves it today. But running a little 250 s/t against a 440 mag would be a challenge. Even the 250 I run coming in at 6200 and shifting out at 9200 would have its hands full running against a 440 mag. it might be close in 300 feet but it should not even be close in 500.
Here's the best thing a twister has going for it, you can take for istance the 250 s/t I race, it has stock cylinders, pistons, carbs, exhaust, it has the hex clutch and stock driven, It is dialed in nicely, will outrun most 250s either stock or modified. It is impossible to do the same with a 76 magnum size for size. Bill Stull was running a 76 magnum in full mod form, only raced that sled one time with my 250 stocker, the merc was much much faster that day. Not trying to start anything with my post, but as always I tell it like it is.

I'd rather be that guy than the nerd out on a pond with his own timing system thinking he has the world by the tail because he races a 30 year old snowmobile. someone should video larry Spindlers 440 s/t stocker at waconia this year, you rupp nuts will see what a dialed in merc sno twister will perform like. |

I'll bring my camera.... I had the honor of racing Larrys liquid Twister against my 440 F/A back in '07 at Waseca. I was NEVER in the race. His sled might have been as much as 75 feet in front of me at the finish line. That was the year I jumped up into the 440 liquid stock and drew the 2 fastest sleds in the class out of 14. I had to go up against Al Ennos '77 SRX and Larrys Twister. It was a very humbling experience to say the least. |
