Possibly a ltd build of speedwerx sc'd sleds to be offered.
heard an intriguing rumour .....
- Thread starter Insaneboltrounder/sjohns
- Start date
Speedwerx has offered a limited build supercharger every year since 2014.

I mean on a sled sold by cat.
No. Average Joe+boosted sled=liability nightmare. I am sure that Speedwerx will be offering a turn key machine as they have in years past, but this is not a battle Cat needs to fight right now.

You're prob right , local dealer brought it up.

They already sell a boosted 4 stroke with over 200 hp. Why not a 2 stroke?

Because every idiot that shouldn't own one will and it would be disastrous for warranty claims.

While I agree with that, if it is factory engineered they could put enough fail safes in to help alleviate some of that. A factory designed 2 stroke turbo could work. Just don't run it on the edge for power.
Could you imagine how many times a season a sled would be in the shop for warranty work with a 2 stroke turbo? They are FAR from pull and go, very far... They would have to come with 0 warranty and you would have to set them up and tune them yourself, no way a manufacturer could set them up for every riding area and conditions.
The inherent problem is the tuning. On a 4 stroke you can run pig rich and you just sacrifice some power. On top, you would not even notice it when riding because it wont cough and sputter like a 2 stroke. On a 2 stroke you can have a target AFR of say, 12.4:1 for the machine to run crisp. If you run 12.0:1 it may foul plugs, or load up.
On a four stroke you may find that optimum power is at 12.8:1..........and you can run that bad boy at 11.5:1 all day long.
A closed loop with fail safe would solve this, but it would also probably add $2500 to the price of the sled.

While I agree with you on this, every turbo manufacturer will swear up and down that their system is pull and go. That is all I hear from them when they are trying to sell a system.

Silber setup on the Axys is as close as pull and go as you can get. The key is hacking the ecu. Piggyback systems are problematic at best. When the perameters can be changed across the whole ecu, then it works pretty good. The factory engineers could do this if they wanted to. Just not sure it is a priority.
Yup I'd have to say my silber axys is truely pull and go. Unreal how great this setup is, and with no gauges. Only reason I got it was because it's a reflashed ecu. I have had nothing but headaches in the past with piggy back controllers. Until Silber hacks and puts a setup on an 18 Cat, I'm out on putting a turbo on my Cat.
Cat ecu
Why is it so hard to unlock the cat ecu and change the factory settings?
Is cat doing something to prevent this from happening???
A super charger and the factory ecu tuned to fuel it might be a good fit???

The ECU for the new motor is supposed to be hackable. Silber said he is gonna have a kit next year for the Cat. Hope he does it.
