Best bottom End/Quick Spooling Turbo Set-Up
- Thread starter tdbaugha
- Start date
Assuming all else is equal,
A good way to underderstand the AR is a pinwheel...Imagine you take your garden hose and point it at a pinwheel, great the wheel spins.
Now put your thumb on the hose and point it at the pin wheel and watch how fast it'll spin... You get higher pressure over "X" area helping your spool...
Higher shaft speed sooner, more low to mid range torque (fun) =)
Now trim, larger the inducer, means higher the trim, and more it flows but hurts spooling, and could possibly cause surging when too big. Spool can be hurt becasue the inducer is taking a bigger bite of air (more work), compressing it and sending it out.
A smaller inducer, the lower the trim, the less it flows, but helps spooling becasue it is not taking as big of bite of air (less work).
Now this is were the benifts of a billet wheel come in becasue you are able to up your trim without being as effected by the downsides, due to being thinner, more aerodynamic, lighter, smaller center hub giving more blade surface area compared to cast...
In regards to sizing 10 psi is not 10 psi, look at it this way, you can have 10PSI going through a straw , and you can have 10PSI going through a 2.5" pipe... what do you think is gonna flow more air? Motors are just air pumps and we are after effeciency.
Its up to the end user on what he wants, if they want 6 psi and taking bark of trees, or 15 psi and big hills.

I hear good things here and may be biased but IMO the ViPec, or similar, is a necessity for low end performance with all the variables that it senses and can control. Sorta like a one stop tuning device. Given, it requires a computer and power source to map (tune), we do live in that era now, if done right should only need occur once. Just activated the Closed Loop EBC on my sled, the mapping update that came with it seems to have helped the bottom end on my sled. In my mind was as good or better than stock before.
My boost it turbo pro has ZERO lag with a seperate water to air system and a Garrett GTX 2863 My sleds throttle response is better than stock. The Boost It Turbo system is a stock sled on steroids. I run a power addiction head with turbo domes and couldn't be happier with the performance.

Best spooling turbo
Just tested another one on a Polaris 800 this weekend with PCV PTI
This is lightweight turbo with custom compressor wheel and .64 exhaust housing, True ceramic bearings cage less, Billet aluminum center section, water cooled, oil less turbo. saved about 8 lbs by getting rid of Silber pump and turbo.

Would this be a direct replacement for a 2012 silber setup

Fast spooling turbo
This customer's sled has been upgraded by Powder Lites first with blowoff valve, then double divorced down pipe and next a PCV PTI with a prototype box to run extra injectors from TJ at Dynojet last fall.
After this customer goes riding on our turbo kit with same PCV PTI and same blowoff valve he wanted Powder Lites new turbo. This new turbo wakes up the bottom end and is hard to tell it has a turbo with being so smooth and much like stock throttle response.
Custom compressor wheel, ceramic bearings and lightweight center section with the only bearing system used on turbos in the world is trick for fast spooling.
Yes it bolts right in place with extra bracket.

How much compression till you start loosing power on the top end? Push Turbo and Vipec were saying that the Cat motor starts to fight against itself at some higher boost because of too high compression.
That was on pump gas, not race gas with the cat motor.

Best spooling turbo
We have been working on this for a couple of years and now having some good feedback we will be selling turbos and kits for 2 strokes as well as our 4 stroke kits. This turbo has custom compressor wheel that works the best that we have seen for spooling up smooth and just like stock sled.

Would you mind sharing who is manufacturing the turbos? I assume that you guys didn't do the design and manufacturing of the turbo?
Yes, I would like to know also.
I was fortunate enough to run this turbo this year and was impressed with it, very responsive and quick spooling. You hit the throttle and its just there, compared to the other garrets ive been around this turbo is very smooth and spools very nice.
One thing i noticed after switching back and forth with a silber turbo, and a garrett, was the garret and silber you could feel "the boost hit".The powderlites one comes on very nicely.Sorry i cant remember who was making them for Powderlites.
Overall a very fun, torquey, Turbo.
Not to mention it is nice getting rid of oil pump & tank, lighter, cleaner, less to worry about.

Many things factor in to that... elevation, IC, turbo size, timing, pipe, head design, what race fuel...
That being said there was a guy with a push kit a couple weeks back that had the money and time to do the test LOL, i believe it was one of the guys over seas.
He pushed it till his motor popped, if you sort back through the polaris tubo threads you should be able to find it.

Yes mapping was way different when we changed to our own turbo.
