Turbo????

[foremanbeast]

hey yall,
i have a 99 foreman 450 and was wondering if it is possible to putt a turbo-charger on it? If possible has anyone done it and how much might it cost?

thanks for any help

i know they have one for a Bomb DS650 but i doubt they make one for a foreman. but you might find a place that might be able to come up with something

It's been discussed before. It's about a yearly topic. Lots of ideas, most of them off the wall, some feasable, some even doable. All are crazy expensive, and will probably blow up in your face the first time they get splashed with water. Sourcing a little itty bitty turbo for an engine this size and with a relatively low redline has proved a bit sketchy as well.
MHO is that a nitrous setup (Check out Highlifter) would be the same benefit you're looking for, less money, less dangerous, more reliable, and more ultimate gain.

I must add however that a Foreman is like a tractor. It wasn't built to work at speed or at the high end of the powerband. Awesome gains of this type at the dyno could difficult to get to the ground.

IMO the Foremans are built to work in the low to mid range, so the best "seat of the pants" gains are going to come from changes that apply to that RPM band. Clutch kits, cams, big bore kits, tuneable pipes with less disks rather than more, that sort of idea.

YMMV, and if you do decide to do something with a turbo, I'd be awful interrested to know what it is that you do and just how it works out.

thanks for your help.
but im not really wanting to putt a nitrous system on it. some day ( when i get the money ) im gona bore it HMF pipe, rejet, and K@N air filter.

thans again

Nitrous is essentially a turbo in a bottle doing the same thing giving you more air so more fuel can be added to create more power. Seems Jake knows what he is talking about, I agree with him, a nitrous system would be way more feasible, and if it is set up right just like a turbo needs to be it will work great. IMO

i would put a clutch kit in b4 i put in big bore kit. a bbk thins out the wall of the motor and produce more heat. there is probably a pro and con to both but i would suggest a clutch kit first. that and i dont know if i would trust the Nos.

What exactly does the clutch kit do. I have a chance to buy one from a guy for like 30 bucks. He says it will help but pulling my 27' outlaws. Will the quad hesitate on take off? Or will it hurt my top end? And how hard will it be to install?

[Jake]

The clutch kit will consist of just a couple of springs. You'll also need to get a front cover gasket.

It holds off the initial engement. In stock form, the instant you hit the throttle the bike begins to move. Awesome feel, many owners of other brands are jealous of that, BUT... to start from a dead stop, you have only the horsepower that the engine can build at idle or just a hair above.
With the kit, you'll be able to rev the engine up just a tiny bit before it begins to move. Not a lot, but it causes a delay. Similar to other brands OEM configuration. This allows a signifigant increase in the STARTING torque available to get big tires moving.
Once they're moving, it's just as it was. No improvement, no gains.

IMO, for the cost, and for the chance that the springs had been abused during an installation and removal, I would look into a new kit with a gasket, or I would make sure I knew and trusted the person selling the springs used.

FWIW, the big bore kits have proven to be reliable and trouble free. They have a bad rap because 1) many have been installed by un/under qualified people, and while these top ends are definately not rocket science by any stretch of the imagination, you do need to have some idea of what you are doing. 2) Many have been installed because "it needed a top end anyway", after being torn up from swallowing mud and grime, however only the top end was ever given any attention. This situation requires a complete 100% teardown and cooler flush or replacement, and most don't get that. At least not the first time around.

If I were you, I'd wait till the clutch gave all the way out. When I installed mine, it didn't really seem to help much for the time put into it( For shallow mud, it's o.k. In the deep stuff, not really a difference). It does have a tad bit of hesitation on the start. But, with my 26" or 28" Outlaws, to do it all over again, I'd leave it alone.
On second thought, a less of aggressive tire would probably be o.k. Never tried that.
