building a turbo kit

[mikesystem]

hi i am new here to this site this is my first post like to say hi to everyone and here is the deal i have got a arctic cat 440 / f7 snopro race sled i droped a F7 motor in to it last fall and its time for more power so i am going to build a turbo kit for it want to keep it simple as i ride at 0 to 1500 feet and ride ditches trails small hills its a all around sled i will be wanting to keep it on pump gas as i trail ride so i as no one makes turbo kits for my sled i have no choice but to build one my self i want to run a areocharger 53 with the max i can go on pump fuel and boost i think that's about 7 or 8 psi ????
i would be using a purelogic fuel controller fuel pressure regulator boost gauge fuel pressure gauge and i all ready have a 4 window digitron on it right now and will be looking for a a/f gauge as well
what kinda luck do u guys think i would have with a set up like that i am not sure about a blow off valve or what clutching i would use yet but hoping u guys could help me out a bit as this stuff is kinda new to me thanks mike

Well is sounds like you kinda of got it. First you really need to think hard and fast if you want a turbo for ditch and trail riding. I have a TM7 that I build my own turbo system. I tried to run it here in MN at low boost and it just wasnt worth it in the long run. Out west well that's a hole different story. I have since bought a trail sled for MN and only use my M7 out west or if I want to go piss off all the rich kids on lake Minntoka.

Now for the turbo kit. You will not be able to run 7-8 on pump gas at that elevation. Maybe 3-5 and that is a big maybe. You can have you stock head cut and that would help.

Do you have expericence in fabing you own parts.

Can you weld Aluminum?

Can you machine your own parts?

I assume your some what mechaincal encline since you manged to stuff a f7 motor in a 440 chaissis.

The reason I'm asking you these questions is not to be a D@#K but these are things you will need to build your own kit. You can fab them out to some one else but it will cost you more then you want to spend.

If you can do all the fab work you self plan on spending about 2500-3000 dollars on a kit.

Also I would not run a Aero. Automotive turbo are way cheaper and more forgiving when it comes to breakdows. They are more work to get setup but in the long run they will last.

I hope this helps if you have any question feel free to ask. As I have more time in these 700 then most do.

Yeah I am good at fab stuff up will post some pics of my sled when I get home and what I have all ready done to it ... aluminum welding and bending is not a big problem I think u guys will like what I have done all ready
now don't u think it would be a good trail sled all the trails i ride i am all ways on and off the gas not wide open to the bar all day and why don't u think i would have a problem running anything more then 3 to 5 psi boost ???as for doing the heads i can do that no prob as long as i can find out how much i would need but no one has said that i would have to do that i have talked to a few turbo builders and they say should not have a problem running about 7 or 8 where i ride ??? and as for the auto turbo i don't have a lot of room under my hood like the fire cats or the M sleds prob about 1 foot less under the hood and if u look at my steering and all round there its pretty tight now i could build it to fit but want to keep it simple as i can that's my goal and i know a guy that's got all most all the stuff i need i think other then and some small thing that i will need to make or buy but that's the other thing now i talked to aerocharger and they said i could run one with out a blow off valve that kinda don't make sense to me but that's why i am here asking so i know what i am getting in to

some pics

i think building it won't be hard as i have good skills here are some pics of the tank i made cause my stock tank was only 4 gal and mine is 11 gal i hope you guys can appreciate the kinda work that went in to it and its a efi tank as my 440 was carb and the filler hole was to small to get the pump in and 4 gal don't last long

 

[mikesystem]

anyone ??? got any info on doing this or what i need ???

 

[mikesystem]

well what kinda of a/f gauges are u guys useing ??? what are them pure logic boxes like to tune with ??

 

[Rms Rydning]

I have experience with building my own turbokits. Its a lot to learn and you will need good patience to komplete the first one...The 2nd and 3rd kits goes way easier. The tuning part might be the worst the firts time.

The #53 is to smal for the F7 engine, I have a buddy who put this on a F7 earlier and got into a lot of problems. That engine is flowing a lot of air and you will have big problem to get this to work because you will be outside of the compressor map. You might get away using low boost like 5-7psi, but then its very little hp gain. On a old Rotax 800 132hp will this turbo work good beacause the rotax have very low exhaust duration and use much less air to get hp, and be perfect for a 600.

You will be much better off selling this 53 and get a bigger turbo like the GT25, GT28RS or #66 if you will like to get some hp out of this sled.

 

[mikesystem]

Now the 53 I would be usein is the big 53 I think it's 145 300 I have it wrote down some where ?? What h.p would u think with the 53 ?

 

[mikesystem]

anyone else got any info for me ???

 

[TurboM700]

Tops maybe 180. The areo at your elevation you should not push past 6psi and you will not be able to run straight pump gas. The charge temps will be to high for that. I'm telling you you are better off just buying a Auto turbo like a Garrett 2871 and being done with it. Other wise you will be building a new kit in a year and you will have a smoked 53 sitting on the shelf. There is a reason most company are not using aero in more. If you have anymore questions feel free to PM me I'm not on the fourm much anymore.

Turbo

Yeah everyone I have talked to says the areo 53 is a waste of time and money better off with Garret so if I used a 2871 what would I be looking at for h.p boost and all that everyone says the areo is a bit to small for the motor

 

[KAWGRN]

We just put a turbo on a 09snopro race sled and used a 53 at 8psi sealevel and it works perfect I dont think a 53 is to small for a 700 at sealevel as I have them on M-7 at 10K elevation at 10psi and dont have a problem with the turbo there ,,,,now the 66 at 10K not good!!!! I think the aeros are good as long as you stay below 10psi at any elevation

 

[mikesystem]

well i just talked to a guy that was going to order a new areocharger and he said areo was out of business again ???? anyone know what kinda numbers i would be looking at if i run a 2871 garrett

 

[little_orange_cat]

around a $1,000 im working on my own for my m8 also check out ebay every so often there will be a score

I just put together my own turbo kit on an m7 with an 800 big bore kit. As most have stated on here the auto turbo seems to be the way to go. I went cheap with a t-28 journal bearing turbo to see if it would get the job done. So far I am very pleased with how it runs and the spool up is not as bad as you would think. I am running 7-8 psi at 8000 feet and so far no problems. I am running a boondocker box with ADA and I love it. Like you I built all of my own hardware. If you want to see what I built I can PM you some pics.

That's a wicked alum tank you made!!

How much does it hold?

I have a spare 1-1 FPR I could sell ya if you want... But am in Canada... Don't know if it would be worth the hassle...

I am in Canada too it holds like 42 liters like 10 gals or so And I made it for to fit my efi pump in the tank and that's the stock fuel cap
