Intro:
I currently have no project cars. I’ve drag raced snowmobiles for about 10 years, including a few years of racing an F7 for Hebeler’s Sales & Service. I can’t seem to shake the rush of going fast on these things so my trail sled has become a racer.
Goal:
Eventually have a 2 stroke turbo setup pushing 500hp and click off a 5.0 1/8th mile, 4.0 in 500ft range for grass and hilldrags. Retain a “stock” trail sled appearance and chassis. Year round racing: pavement April-September, grass September-November, snow/hilldrags December-March.
Sled is a 2009 Arctic Cat CFR1000. I bought it 2 years ago with 650 miles. D&D ypipe and pipe, Boondocker fuel controller, V Force 3 reeds.
After bringing it home I immediately replaced the track with a new 1" hacksaw track with 204 1.375" studs. I also worked on the clutching (I do 100% homebrew clutch setups, no “kits” here) and I took it to DynoTech Research. On pump gas, cranked out 195 hp and 134 ftlbs.
I did some trail riding, and also went and won some races in improved stock type classes.
Then I decided it was time to try pavement.
Lots of time spent swapping around suspension parts and setting ride height, putting in coolant quick disconnects, etc.
I also realized that I could barely touch the ground to do burnouts so I got another seat and to cut down and reshape the foam.
I also shed about 15 pounds going to a lightweight muffler and added an AEM O2 guage
And of course had Dan Delaney of Dan the Sign Man do his magic on some vinyls for numbers
By this point I had to have surgery to have my gallbladder removed. But I still got in about a month or two worth of testing at Lancaster
Where I got my first perfect .0000 reaction time
and eventually clicked off some 5.9x passes including this 5.92 with a 1.28 60ft
By this time the fall semester had started up so the sled just sat for a bit. time to take things apart.
I had the front a-arms chrome plated, had the spindles powdercoated gloss black, shined it up real good and put it in the buffalo motorama with my buddy’s sled
By spring time I had been doing some “dickering” as they say and through some trading I landed a second 2009 CFR1000. This one, with a D&D 1200 big bore. Now the plan is to take both sleds, swap motors, return the “new” cfr to stock and sell it.
Specs on the new motor:
D&D 1200 big bore
Stage 2 / lake race porting
True & welded crank w/ new bearings
Powervalve deletes
D&D trail twin pipes.
Before putting the motor in my sled, I also did:
Removed the nitrous system
Cut the head to a .055 squish from .080
Increased timing key from .030 to .060 for about 5-6* of timing
Added my V Force 3 reeds
Removed the BDX throttlebodies and put stockers on
Shortened the “header” section of the expansion pipes 1" to raise powerband and peak rpm
I also made a flange to mount some air filters in the nose cone area since there was no room for the stock intake assembly with the twin pipes
note the fabbed clutch cover
By this time it was ready to dump some C12 in the tank and head back to be dyno tuned.
The changes I made since acquiring the new motor bumped the N/A power from 207 hp & 150 ftlbs to 230 hp and 155 ftlbs.
I unfortunately had been in a car accident where I was rear ended and my back was fubared preventing me from getting to the track so I took my time doing the swap so now we are to Fall of 2014.
By this time I had also assembled a complete 2nd rear suspension for snow/hilldrags and I started assembling a 3rd for grass drags.
Of course everything I do now is powdercoated and not paint
chisel track, again one of 3 setups
and the sled set up for grass
by this point im testing grass setups, and never made it to a race. Instead I ambanging my head on the wall because the damn thing keeps going in and out of running on 2 cylinders, to 1.5 cylinders. I change sparkplugs, fuel, boondocker fuel controller, boondocker wiring harness, have the injectors cleaned and tested, still no change. I have now ordered 4 new ignition coils (2 sparkplugs per cylinder, 1 coil per sparkplug) and will change out all coils. Did it with stock motor, then went away. Now its back.
I also decided it was time to reduce weight. so I bought this
and started this
to get this
This reduced the amount of air in tank to preserve fuel, and instead of having to keep ~3 gallons in the tank I can run less just under a gallon. it will also give me room to access the spark plugs without having to remove the exhaust pipes. All while looking “stock”
relocated my fuel controller after the gas tank mod
oh. I also broke this from having way too much compression. had to order some stronger rope. can barely pull it over when cold.
and collecting parts for every racing season.
So that gets you caught up to current. Right now I am working on shedding some more weight on this, and getting ready for some snow/hilldrags. I’ll be racing all king of trail/king of hill/whatever else they will let me run. Come april, Ill be switching it back to pavement and shooting for 5.50-5.60 1/8th mile.
Very nice sled. props on the perfect light!
