whats best for the XP800 Turbo size?

[Sickbuild]

Ok so I just got an 800xp sled seller said it had 2010 motor, nope....

all new front engine cradle, yes.....
looks as thought the engine is a new 08 or fresh rebuild, but I am still going to rebuild with RKT pistons just so I know what going on in there.

right now it is getting the tear down. " Ride from 5000ft to 9ish , boondocking and a few long pull type riding"

So my question is; I keep thinking to do an aerocharger "budget" build but am new to them and want to know if a larger 53 series will work right or go with the 66 series?
Then fab up most the rest?
I have a 146 track and skid on it and it would have to go, soo just trying to see if i can do it money wise etc.

66 is a must if you wanna make real power. aero's being self contained are a little more simple to install. but im still a big garrett person. 3071 is what you really want, yes you have to do oil pump/tank but heck i think there are a few kits using smaller garretts for sale in swap meat for pretty dang cheap.

with a 146 your not going to be going super high with the boost but a lower boost sled would be stupid fun with the shorter track!

53... too small

A 53 is too small. Been there before, go right to the 66!

 

[Sickbuild]

Thanks guys just wasn't sure if the 53 was not quite big enough

 

[TreeThrasher]

Yep, same idea as the guys above. If Aero, go 66 for sure. I too am a Garrett fan though. Ive run a 2871 and a 2876. Good results with both but I would definatly recommend the 76. Heard good things about the 3071 as well.

I like the self contained part of the Aero but prefer a water cooled turbo....we shall see how my new custom frame Comp billet wheel turbo does next season Hoping for the best of both worlds!!

The 3071 or 2876 are fantastic turbos with no limits or surprises.

dont set yourself up for disapointment, go garrett and forget about it.

From a guy thats been there and done thats point of view.

Is there a particular 3071? I see all sorts of styles. Tial v band etc? I got my sled torn down to the rivets and plastic these last couple days.
My motor is on the floor and is going to start getting torn down tomorrow. I am going to check runout on the crank and put some rkt pistons in in the next couple weeks.

It just seem a lot easier to aero and I can get them cheaper and part since a dealer lives a mile away,

I also don't know what types of things I'd really need to build up/fab a garret...I can fab or have fabricated most of it but just understanding the sequence of it all?

But it looks like i need to learn.. thanks guys(looks like i need to start getting $$$) New plastics,doodocter clutch, etc the list goes on

get a .84 ar 3071 and dont look back, total cost is 1384 $ you cannot get any other NON e bay turbo for that money. NO where NO how..With a wastegate to boot.
contact atp turbo tell them Gus sent you.

or I can set you up complete or turbo boyz . or dooin it.. none of us would keep a secret dude..

good luck and fab away. You will not regret it ,, not for 1 minute .

I will have a PAR 1640 triple triple turbo at dynotech in just a few months. look for the 800 hp barrier to fall at 25 psi or less .. Thanks to Brad Wersten and Jason Potvin.

what elevation are you gonna be running it at. if its only really high we have had good luck with the .64 housing just due to lack of air compared to sea level type stuff. nothing even gets idled below 3k feet for us.

the internally wastegated ones are the ones you want for simplicity. If you want PM me your number and we can chat turbo's. just to much to sit and type away at. much easier to explain with words.

With the 3071 compared to the 2871 it sounds like you will get more HP on top lb for lb of boost. For the same amount of HP then you will be able to run lower amount of boost. Lower boost means lower charge temps, extended reed life, and lower fuel requirements. Just takes a micron longer to spool up if I am understanding this right.


One question. At what Lb. of boost would it be beneficial to choose a larger turbo to run a lower octane and still get the same amount of HP?

Example:

2871 running 10-12 lbs of boost vs. 2876 running 8-10 lbs of boost?

or

2871 running 10-12 lbs of boost vs. 3071 running 6-8 lbs of boost?

Something along those lines making the same amount of HP? I am putting a turbo on my sled too this year still and want a solid 215-225 hp on straight AV or less some days and then tuning it up for straight 110/AV mix. Just want to get the best turbo for me from the start. Thanks.

Visi, Its a tough one. The larger diameter of the 30 hot side allows the .64 ar wich spools in boost under 3000 rpm, as long as you are over 3000 feet up the tighter ar is perfect.

so the real gains of the 3071 come from a better FIT of the hotside making driveabitlty better.

the looser hot side of the 28 series at .84 ar is not as efficient so jumping to the higher flowing 76 compressor brings you back the low and mid you lost from the loos turbine. At sealevel the 2876 spools in at 2800 rpm.

for the mountain rider with an under 900 cc engine the 3071 .64 is dead on perfect. you can run it up past 28 psi if you dare and it will still be working as it should.

have fun, Bottom line is thru diligent testing many have realized the 3071 is better than the 2871 all around at alititude.

lol. they are good at any boost level. only better.

i am rockign the internally gated 3071(which has the smaller exaust wheel 56.5mm and a .64 housing) at around 6# on my 700.

my buddy is rocking a full size 3071(60mm exh wheel with .63 tial housing) on a 800 running 3.3# externally gated. its even worth it at those levels!

and if you build a 30 kit for your xp, get it dial in at 6-8# its gonna pump/100ll mix you can turn it up more but with a 154 your gonna be hauling *** everywhere in a wheelie no matter the snow conditions.

 

[Visi]

Thanks guys! Sounds like I'm sold on the 3071 with the .64 housing that's externally gated. Going to see how 6-7 lbs. feels first.

Keep us updated Mike, hows th back doing ?

BTW, call high performance engineering, order new reed petals for your stock OEM double v cages, double up the reeds and hang the fawk on.

Much better response than the boyesens, zero failure zero chipps and under 100 dollars to do the entire job. Thanks again to ELI for doing a full season of riding evaluating these for me on the POO too..

shoot me a direct email. gus.bohne@comcast.net and I will send you pics of the cages done as I would for my customers.

have a blast bro. turbonetics 38mm gates are my favs. be carefull on tial gates from ebay. THEY ARE not tial gates. cheap copies. tial has identified that and has changed their numbering to expose this fraud.

Gus

As you all know I am no fan of the e torch, Looks like Gus is going POO for his trail turbo..cant bring myself to even consider a torch. like going gay.

 

[Visi]

Thanks for the info Gus. I will be sending you an email soon. My back is getting better, physical therapy three times a week for another month. Spinous fractures on S1-L3, Transverse fractures on L4-L1, Bulging discs L5-L4 and S1-L5

 

[TreeThrasher]

Gus, what are you seeing fail on the etorch sleds?? I have one ordered with plans for a turbo too match my r motor turbo....

Looking forward too the PAR 1640 setup, absolutely killer package!!!

Thanks for any info!

 

[gus bohne]

Thrasher, they are far from consistent,,, and pos clutchs, pos injection system, pos suspension. My feeling are mine, just like anyone else who buys a sled .

Not 1 thing makes me want to own one let alone add boost, heat and load to one.

In the northeast we have icy trails low snow and lots of overheating issues. now add a turbo to that, and our notorious long 45 mph flat sections at part throttle and you will over heat, deto, throw codes chase it back to the dealer and then walk away.

I love the doo's but the trolling motor injection system they bought from OMC isnt finished being converted to 8000 rpm yet. I'll let the other consumers pay the tab on that job..

So its injectors into the case for me.. that means poo... the cats have lost their chassis since they went to the ( swinging jackshaft )..lol

Now, in the deep snow you have longer extrusions, much much cooler running and of course much higher track speed to vehicle speed ratios. TSS / TP have a well thought out set up. I love the fuel supply, and love the ( you can buy it anywhere ) of it. the monopolizers are shot in the foot now..

Wish you the best man.. it will be a better yr for the torch turbos out west now that anyone can fuel one and not have to deal with 1 theory and supplier.

Back to our topic.

[TreeThrasher]

Thanks Gus! I will give it a go and see what happens.

Back too turbo sizing, if you were too use a comp oilless, what size would it be?

Thanks!

 

[gus bohne]

My only xperience was a test unit and it was not what I wanted.. Im sure they have more time on them now and with OVS using them more feedback too.
