Mikeyd,

Super job on the turbo.

I just got my RTV1100 and could not believe how slugish it was and was in the process of researching a turbo instl when i found you project.

In your research, did you come up with any other choices for turbos other than the MHI TD03-7g?

Since i wil be looking for a used one, i would like a couple options.

Thanks, Chuck

Ps, thanks for sharing all the photos wiht the forum

hey mike! got a question and if anyone else wants to please feel free to chime in . i posted your turbo project on another websight for someguys who was lookin for a mod for the rtv. but i got bashed by someone who jumped in and said this turbo does nuthing to add speed to the unit and said it only adds power and that your daul exhaust doesn't add nuthin too. well i had to disagree . from what you stated in your post is that you was lacking power and you could barely get the rtv up to 17mph now she gets up to 27 easy now i know the trans will have alot to do with it but if you add more power power equals speed so to me your setup will increase your sped by a few mph but the main benefite is the power to get up to that speed faster. so if two cars are racing and one does 0to 60 in 2 seconds and the other does 0to60 in 6 seconds that means the 2 second car is faster right??after all the 2 second car will reach the finish line first . so in my belief is that your system increase speed my about 4mph maybe a little more you have to give some to the tires but it does increase the speed.

another way to look at it is without the turbo how fast would the rtvgo?17mph right and then after the mods your getting 27mph thats an increase in speed power and speed .now being you the one that built it how do you feel about my thoughts are they right ?

I'm was running the 27" 589's, and on flat ground, hard black top ( just to test speed )
27 mph ... That's streached out !!!!
The only difference between my RTV & my friends, is that I have a ROPS High Rise Intake. ( His hasn't come in yet )
He's getting 24 & 25 mph with his, he says mine is faster for reason of the High Intake, machine is getting better intake air ~~~~
Both full of fuel, runs were with two men aboard, both has the spark aresstors removed , Temp 35 degrees that morning ~~~~

We checked them with GPS ****
As far as I'm concered, that fast enough, we done this speed test a couple of days ago. Probobly will ever put this machine back on the black top again, nor run that fast ~~~~~~

:cool:

i know the tires will add speed but the turboshould help out with the speed to if it gets you to top speed faster right?

If he was able to reach max engine rpm before he installed the turbo, then the turbo will not make a difference in the top speed, it would possibly make him reach max engine rpm, top speed quicker. If he wasn't able to reach max engine rpm before he installed the turbo then the turbo would make the top end faster, clear as mud?

well from 17mph to 27 mph thats an improvement right?
this is c/p out of the first post of the thread! thats an increase in speed so to me it does both speed and torque. more torque than speed but it does both.



"Proof of performance is that prior to turbo the highest speed I could reach in high gear with the 27" Essex surefoot tire kit was 17mph( was near 30mph with stock worksites as I had already turned up the pump when I first got the machine). Now I easily and quickly reach 27mph in high with the Essexs' on. I have a ton of pics from beginning to end. If you guys want the pics of the fit up etc. I will be glad to post them.Below are a few of the project as I had it running tonight. Enjoy!!"

Well yes, but the top speed of an RTV is supposed to be 25mph (give or take) right? So technically he didn't gain any top end speed but rather just got the speed he was supposed to have before. 2mph gain can be attributed to about anything, larger tires, miscalibrated spedo, kubota rounding down the speed. I don't know what it was that caused him to be going 17mph in the first place though which is weird.

You're right about the acceleration though, that would have to be improved.

Ok either you added on that last bit or I just missed it tommy. But that gain wouldn't be there for everyone just those who had really heavy tires. The engine didn't have the power to turn them as quickly before. However for someone with say those light 489s wouldn't see any gain since you're limited by the max. ammount of revs the engine will go to.

the way i'm reading it is he had stock tires on it and he tirned the pump up and it was doing around 30mph. then he put the 27's and it would hardly get up to 17mph now with the turbo it get right up to 27mph quickly and easily . so thats an increase in speed whenhe installed the turbo from 17mph to 27 mph.
