T3 SHR 860 with Aerocharger Build

[nuttyn01]

I thought I would post some pics of my T3 build. I have been running my aerocharger on etec's since 2011 and have been very happy with the performance but thought there was room for improvement on booth the bottom and mid range. I felt this had more to do with how the etec motor is designed more so than the turbo system.

I hooked up with John this summer and we started milling over what to do with the 800 etec. Originally, I was looking at porting the stock 800 motor and massaging the head a bit and going with dual ring wossner pistons. As it turns out, it is very difficult to find bad etec cylinders and I had a hard time justifying grinding on a good set. I opted for a set of snow x cylinders. You can order snow X cylinders for the etec in whatever bore (within reason) that you desire. So, we decided to go with the 860 for the additional torque along with headwork, porting, and wossner dual ring pistons.

So far the sled has the following:

-SHR 860 BB built specifically for turbo application
-aerocharger turbo with my "left over garage parts" intake.
-TKI belt drive
-clutch lightened and trued by SHR
- next level windshield bag

Still waiting on:

-race worx front and rear bumpers and boards.

might consider depending on reviews:

-skinz arc coupling system

I put a few miles on in the ditch this past weekend before the snow was gone. All I can say is "mission accomplished". The throttle response is BB like and pulls all the way through the RPM range.


I havent touched the clutching from my 14 and its pulling at 1500 ft with 5lbs of boost what it would pull with 9lbs of boost at 9000'. You cant argue with clutching

I can't comment on the longevity of the motor at this point but I am honestly not concerned as I have always had good luck with John's builds.

Here is a short vid to illustrate throttle response. This is an idle to full throttle stab...super clean with no stumbles! Kind of a lame video with virtually no snow but you get the idea.

More vid to come when we get west or get more snow in the plains.

Oh, by the way, if your debating between challenger extreme 3" or T3 3". I have run them both and the T3 3" is going to be a more well rounded track IMO. My challenger 3" would not have hooked up in most of what I was riding in yesterday.

That thing is awesome!

You better come out and say hi and ride with us!!

Cool build...looks real nice.

For the price of the ARC, you're 2/3rds the price of a skid package. Emotion isn't too much more than the Arc.

Nice, should have climbed the bale! Question about the pro-x cylinder, did it include the plating cost w/ the 860 bore. May have to order one at 880 specs and send it to BJ for porting for my turbo.

Might take you up on that Nick

They come raw.

Sick build, it sounds awesome!

what was the cost for the Sno X Cylinder?

 

[nuttyn01]

what was the cost for the Sno X Cylinder?

I think they were right around 399 raw. You would have to ask John to confirm.

 

[TreeThrasher]

You will love the big bore turbo.. I have been doing them since 10/11 season and there is just no comparison to a factory 800 setup. More power on less boost, sick bottom and mid. A better and far more reliable engine for Boost!!!!

Have fun!!

Nice build bud.....are we ever going to hook up...lol?

Doing a bb for the Aerocharger this year for the very reasons you mentioned, lower boost and happier motor, and was hoping for even better low end grunt with the 174

Be going with a 880, and wanted to see what changes you are nutty have done to your fuel controller settings over stock... Is there just more fuel needed down low, or not really any changes needed?? We ported bottom end cases as well

Would like to keep boost to six pounds at the 7000 feet I plan to ride in, run aeros lightened ported turbo setup...

Running 23 grams on primary with 415 ramps, 160/290 spring and it has spooled very quick in the past, was hoping to add just a gram or two and be done, have you guys done anything to your primary's, did you see any over rev after spool

Are you running the snow/air air box or the older setup? Have you stuck with the turbo reeds or found better... I have been running the tdr and they have caused no issues to date, was planing on continuing to run them

For gearing i had been running 2.23 to one, end of season I tried the 2/1 and it still ran well but only ran half way up the primary, might be better with the bb

Appreciate the help... Thanks

BB

Fred,

I am running a T3 163".

Fueling:
I think you will find that you dont need any additional fuel on the bottom. In theory, by flowing more air with case porting and additional cc's, this should help gobble up the fuel that the current tuners are unable to pull pre-boost.

Clutching:

If you like the 415 start I would contact DJ and look into a set of his mountain ramps. They are a 415 start with a 441 finish. This will help get rid of some of your primary weight. You might also consider 1mm oversize rollers. Increases shift force and also helps reduce pin weight.

My current clutching set up:

primary: DJ mountain ramps, 240/290 titanium spring, 1mm oversize rollers, 19.6 grams of pin weight. SHR primary mod-starter ring gear removed, machined for full shift and lightened and balanced.

sedondary: 40/48 reverse helix with 185/315 spring

I am at 5lbs of boost at 1500 ft and rmp's are spot on. This should put me at 6lbs from 5 to 7000' and 7lbs at 9000' +

I am running double stacked stock reeds(stacked reed cut half way back) on the outside and stock reeds on the inside. I ran the TDS reeds on my carbed doo turbos. They are bullet proof but are pretty darn stiff. They might be hurting your bottom end air flow.

I am running the TKI belt drive and with the conversions i figure I am some where around a 2.35:1.

I am also running the ported aerocharger with the 2011 charge box/charge tube set up.

hope this helps.

Good Luck

thanks shawn. maybe this is the year How far are you from cooke city again?

Nice build bud.....are we ever going to hook up...lol?

Fuelling idea makes sense, might increase fuel a bit on wot...I ussally run around the 12.8 to 13 on a/f on wot looking back at a few vids

Second look As for Ramps I still have in toms alum ramps. Very similar to the 414/441 and run the 1mm over size rollers... The Lower Start force on primary spring ussally dictates more belt squeeze does it not?

Run the standard shockwave helix at about 4.5 turns out, did try the reverse cut ramps but thought it was spongy, not sure if your spring is aftermarket but mine is the stock, might have to try the stock reeds double up

Is your gearing taking into effect driver size? And seven tooth drivers
