I follow what you are saying and agree with you too an extent.
And I COMPLETELY understand the cost factor in arriving there. Totally get that.
However, I would also counter (and I'm sure you understand) that power to weight ratio is far more beneficial to the rider when the chassis weight is less.
For example I'd much rather ride a 350 pound sled with 175 horse than I would a 600 pound sled at 300hp.
It takes more money to remove weight than it does to add horsepower, but it wasn't always that way.
In the old days, up until about 12 years ago, it took $100 for every pound to drop or HP to add.
It's not so easy to drop weight now when sleds are 100 pounds lighter than they were a decade or two ago.
We would buy heads, pipes and port/polish a sled for $1000 to gain 10-15hp (and that was a hot sled).
the concept of the sled is cool but just so unpractical with the cost of it all mods! 15 for the sled 408 pounds 17 for the mods 370 pounds. so for 32 grand you to can have shaved 38 pounds off your buddies and gained 20.6 HP and 9.4 pounds of torque {or their about all depending on your elevation}. so say 180 hp / 370 pounds = 2.05 hp per pound... now a turbo can easily give you 200 hp at a constant {regardless of elevation} and add {well the one I run} less than 3 pounds more than stock so a 411 pound sled. 200 hp / 411 pounds =2.05 hp pre pound and the turbo costs around 5000$. the NA sled will loose hp as it gains elevation so the power to weight will drop rapidly but the turbo can hold the hp as it gains elevation and will quickly out preform the NA build, not to mention that weight savings tend to weaken some parts and cost even more to fix/maintain....like I said its cool but seems so far from practical in my reasoning that I cant see building it or having it built for me! not saying that some of the products in his build wouldn't be unreasonable to add or worth the cash but some are a bit heavy on the wallet for what you are getting IMO. but to each his own im am pos. that this sled is worth every penny to someone!!! well that's my 2c on the build
