Turboed Husaberg 501

[SnoFro]

Has anyone turboed a Husaberg , KTM, or Husqvarna 500? And if so are you happy with it or do you wish you used something that revs more? (450)

Ive been wondering the same thing. I have 501fe and thinking of more power already, curious to know who has done it and who will say get a 450, then turbo that bike. Never tried a turbo bike, but thinking 450 turbo might be better for the climbs and the 501 with a turbo for boon docking thru the trees, maybe ive got it backwards with lag time and certain boost pressures for certain applications.
Im sure there lots are people out there building different setups that dont include turbos , so what works best for the husky,husabergs, ktm 500
I would prefer not to turbo but if that what it takes then its got to be done.

Put a 2.5" track on it before you turbo it. The climbs that I was switchbacking up with the old track I can pull straight in a wheelie now... and thats with a SXLT, the full width lt will climb even better. You can do some head work, flash the ECU, exhaust and im sure a lot more depending on what you want to spend to get more power. I haven't been impressed with the turbos. I hear the KMS ones are working good but the motor and drive systems will have a lot shorter life span. I haven't seen anywhere besides straight up climbing that a turbo is a benefit over a stock bike. The 501 is a really detuned bike stock so there should be some room to make improvements.

I ride a KTM 500 with a self-designed turbo kit.
It works very well and I'm very happy with it.
Have not tested a 450 turbo but feel that the 500 has high torque and it starts boosting early. Full turbo pressure already at about 6000 rpm.
There are of course different solutions to build a turbo kit. Good and bad designs.
Therefore, you should probably be careful to judge out all the turbo builds.
KMS seems to do everything thoroughly and cut no corners to build a turbo kit that provides good driveability and reliability. There are more questions in Boondockers design and looks to be a simpler and cheaper construction.

Reliability-wise the 500 engine manages turbo very good if you do not boost too much, running with good fuel and avoid overreving. (Boosting 10 psi, 102 octane race fuel and a 10:1 low comp piston)
Have today ridden almost 100 hours on it without rebuilding it. (The bike was brand new when i installed the turbo)
Another advantage is that the 500 has a plain bearing crankshaft. It works with higher oil pressure and can handle higher loads than a roller bearing crankshaft.
Because it is so powerful you do not strain the engine unnecessarily, and with relatively low revs.
It is written much about the downside of wide-ratio tranny but I feel it very suitable for the turbo bikes. It revs up so quickly that a cloe ratio tranny results that you more or less hit the revlimiter all the time.
