Custom M8 Tial Turbo Kit (w/ Boondocker controller)

[offels33]

For the past few years turbo sleds have been out I always thought I would never turbo a sled of mine, 1. Didn't want it to be unreliable. 2. Thought it would take away the challenge of climbing big hills. However with the technology and the many many different turbo kits coming out I thought I could use this and put together my own (Custom) kit to fit my exact needs. I started ordering parts for the build through out the summer. (to make my self feel like I wasn't spending so much money) Now that I have all the parts I'm going to start putting it all together on my 2010 M8 SnoPro 162". Me and my buddy have just started the project and hope to be done by the end of the week. I will try and post pics asap. Heres some of the goodies.....

Parts List...... (Custom means I made it or modified it)
Garrett BB turbo with tial housing
Tial wastegate
Tial blowoff valve
Custom intercooler
Custom oil tank
M1000 throttle bodies
Boondocker box w/ wiring
Mountain Fit Hood vents
Big boost gauge
Turbosmart boost T
Koso egt gauge
Custom reeds
Custom support bar(cut-out factory brace)
Custom secondary inj.
Custom pistons
Custom porting
Custom exhaust

Good luck with the build. May I ask what you did to the pistons to make them custom or modified?

Looks like a great start to another good build. You will have to let people know if you ended up saving money over buying a kit.

Keep posting up the pics.

I drilled, cut, and shaved a set of pistons. Kind of a R&D project I'm trying.

early Christmas!!!!!

Well I got the last 2 major packages I've been waiting for late this afternoon, one of them my turbo!!! Got my whole top end back together after I finished customizing my pistons. In the process of putting the pistons in I split my finger open pretty good on the fresh tunnel porting :0 But its all part of the fun. Put my reeds together and swapped throttle bodies. In the process of lining up my turbo with my pipe and exhaust. Taking the day off tomorrow for the big turkey day. But will update again friday most likely.

Looks like Christmas, not Thanksgiving

Looking good. Where does your turbo oil return line dump back into the tank ?

 

[offels33]

Didn't get near as much done today as I wanted too, ended up having to haul christmas trees!! The oil drains into the top of the turbo as you can see in these pics.

Looks good watch those SLP pipes they are usally to thin for a turbo and will split apart.

Haven't got as far as I was hoping, but making progress. Had to work on a couple of my buddies sleds over the week and ended up working more than I would like, haha. Got the exhaust done and started on the intercooler. Here's a few more pics.....

LOOKING GOOD THE INTER COOLER HAS ROOM FOR DAUL FANS ON THAT BAD BOY LOL!

I was just thinking the same thing for the intercooler.


Nice fab work and welds!

looking fast cant wait to see it running!!

Worked on the sled a little bit tonight. Got the intercooler mounted, and the runner tubes to the throttle bodies done.

As with any engine, the more air you can feed your turbo equipped engine the more fuel you can add and the more power you can make. 2 factors effect how much air your turbo system equipped engine gets:

-Boost pressure. The more boost pressure you run the more air you force into the engine and the more power you produce.
-Air density. The colder the air, the more dense it becomes. The denser the air, the more your engine can use on a given combustion cycle and the more power you produce.

As turbo systems increase boost, the temperature of the intake air increases (following the laws of physics). At certain boost levels this rise in temperature becomes dramatic. An intercooler mounts between your turbo and your engine and lowers intake temperatures, allowing the air to become more dense.

For example, lets take a test 800cc engine, running 8200 RPM, at 8000 ft elevation, and 32° ambient air temp.

If we take our test engine and boost it 8 psi, with a reasonable turbo compressor efficiency of 72%, our compressor temp rise would be 116 ° added that to our ambient air temp of 32°, we would have a charge air temp of 148° and make approximately 194.7 HP.

Now if we were to add an intercooler that is 60% efficient, our charge air temp would drop 70° leaving us with a charge air temp of 78° and make approximately 220.1 HP, a 13% HP gain.

Let’s take our test sled and bump it up to 15 psi. If we use the same compressor efficiency of 72% our compressor temp rise would be 185° added to our ambient air temp of 32°, we would have a charge air temp of 217° and make approximately 239.6 HP. (at this kind of charge air temp you would most like experience detonation)

Now if we were to add an intercooler that is 60% effective, our charge air temps would drop 111° leaving us with a charge air temp of 106° and make approximately 286.6 HP, a 20% HP gain, and no detonation

and the best part about that math is that your still assuming no heat soak or the likes.. and 72% compressor efficiency is a pretty high guess, so those are fair numbers, not really taking it to extremes.

A well done intercooler on a sled can be VERY effective, its freezing arse cold out, so you got lots of good cool air to keep it workin well, the key is the fan and good venting.. then you got a recepie for big power and longer motor life.

looks like a good build, keep the updates rollin.

Where did you get that

copy and paste, pretty easy.

I was just teasing yeah but usually when you poach someones info you give credit to them you don't pawn it off as your own.

Your build is looking sweet. Did Keith do the porting? can't wait to see it on the hill

 

[offels33]

I never claimed I said anything, copied it off of another thread thought I got the address on there... Obviously didn't not a big deal. Me and Michael did the porting... Keith has taught us how bc he can't do it anymore. Got the intercooler done today and looks great. Will upload pics when im on the computer again. Have to put secondary injectors in, wire everything in, and we'll be laughing. Hope to test it out all weekend.
