i always find any mods pretty neat, and i don't want to seem like i'm knocking your ride - i'm curious about how these new gators handle all the power. can you actually use it under other than glass smooth conditions?

i'm curious, because i don't know anyone who has one of these personally, and based on the price tag, i don't expect anyone i know to buy one and put it through the paces that i have in mind. from 2000-2003 we used to do a lot of atv riding on the weekends. we covered everything from woods trails to gravel roads and multiple foot deep mud. we had a pair of polaris sportsman atvs - 400 & 700. the groups we rode with pretty well represented all different manufacturers and models, and out of them, the sportsman series was the one that filtered the most abuse out of the space between ground and rider.

over the years the gang all moved on to other priorities, so we don't ride anymore. we sold both wheelers and bought a 2006 gator hpx since we needed the utility more than the ride. i knew that i would be giving up a major amount of ride quality, and i wasn't wrong. bumpy terrain on the hpx at 10 mph is worse than 30+ mph on the sportsman. i understand this to be true, and i understand that they are apples and oranges, otherwise i wouldn't have bought the gator. it just seems to me that they are targeting the new gator as more of a flashy, sporty ride, and not just a hay hauler.

i'm just curious as to how this gator compares in ride quality to say, a normal polaris ranger. i don't know what else to compare it to. it's not the same as a ranger, and i surely won't try to compare it to a rzr, teryx, or rhino. i'm just wondering whether they've come up with enough engineering in the suspension to handle a 50mph machine safely? i can read the spec sheet myself, so i don't care about weights, wheel travel, and the things i can read off the brochure. i just want to know whether it works under power in the rough terrain, and can take a lot of hard abuse.

We've done a lot of 3 cylinder turbo work, would be curious to see how much boost you get.

Just looking at the turbo I think I have the answer.

my gator handles/towes/hauls/ GREAT in my eyes when it was stock. i have NO complaints and i love it. i guess you could compare it to the kawasaki mule or bobcats new utility vehicle as their toned down in the less than 40mph range. no comments on turbocharged yet as i just got it running tonight and only poked it a few times so im taking it easy.

big krank; i've talked to you before about some input wiht pumps i think it was. anyway the charger's a gt12 and i dunno wat my boost is, no gauge yet. i'll be installing that tomorrow when i get a fitting im waiting on. tonight i only poked it lightly around the yard and never jammed the throttle full so i haven't loaded it up yet to it's full potential; PLUS ill be needing to play with the fuel adjustment and rpm still...it JUST fired tonight. what do you suspect my boost to be?

If it's a GT12 you may get a couple pounds, I thought it looked bigger and you would get zero. Hard to get any more w/o engine mods. You can tighten the wastegate up as it is set mostly for a gas engine.

got my gauge installed; a bit lower than i expected by im not complaining, my goal wasn't to be a boost machine! sitting at 5 lbs. max comfortably. gotta feeling it's partly due to a rubbed down compressor wheel as the turbo was smoked when i bought it and i didn't buy a new compressor wheel when i rebuilt it; either way im happy with a low 5 psi! seems to plow through snow a lot better too, more guts and pulls nicely through the deep stuff!

Im Doing a Turbo mod to my 850d I have some questions about where I might hook my return line for the oil? I have acquired a GT15 Turbo which isn't too much bigger than the GT12, Since this is custom I don't know if that's the right move or not. If anyone has advice on this that would be great. Thanks
