Dyno Pull + Graph at 7:56 I know the chains loose The Initial Wastegate spring was only 5 pounds not 8 like stated in video. Found it to be 5 pounds after pulling it to turn up the boost. The Final boost pressure for the 82hp run was 7lbs on pump fuel
You should add a softer spring and use a boost tee regulator to adjust the boost to the psi you want to charge. That made preassure mutch more stable. When i only had the spring the wastegate was acting Wird.
That's dangerously powerful. Amazing job👏. By the looks of it, you also gonna need to put a bigger fuel tank on the bike and of course some protectors for that turbo and all those tubes before letting someone to ride it to it's full potential on a track and etc.
It would be great to install a turbo on a 2t 500. The turbo is already installed on 2t snowmobiles, but it is complicated. The power gain is only 20%. Now we're getting a 4t. The weight-to-weight ratio is more powerful than the 2t. And that's unfortunate for the 2t fan.
@@913outdoors i hope so after logging the second trip, i had readings of 17 psi at Max. So i have to turn the boost controller down abit. But even i have boost i cant say that it feels like i have insane amount off power. The bike is fast. But i was hoping on having a deathtrap. But Maybee is becous of to mutch timing retard, i dont know. This is my first turbo build so iam Learning by doing here.

Very cool stuff but whats the point to put on a 450 mx bike? 90 percent of the people who own a stock 450 can't handle it properly because of the power.i would like to see it on 250.. Great respect though fr ur knowledge and building capacities 👌👌👌
How much would you charge me to build my 2001 Bandit like yours With the custom fuel /oil lines and the Garrett turbo plus all the other Genius parts you created. You are the Dale Walker of our generation (80’s & 90s babies) I would say you’re the best most sought after person for Bandits and CB750s in the US. Bar none Plz get in touch w me Justin Please
Now u going to build a much bigger air cleaner pod to cope with demand.. choking it out with that first attempt is comical at best first time u lay it in the dirt its going to be lights out..
Is it just me? .. but on the RHS going into the turbo is a tiny air filter right at the point where there's gonna be a heap of either dust or mud, and where you're gonna kick it with your boot?
Ya know it’s cool and all, but I feel it would be totally useless on a moto track The 450’s have plenty of power I find myself looking to tame them more than asking for more out of them.
stock 690/701 is at 90% duty cycle at full throttle :D did you just correct fueling based on tps and not on map sensor?! Don't know how this should work when riding normal..
It was tuned based on the air fuel ratio out of the tail pipe. Map sensor is eliminated altogether because it was causing issue under boost (it's only made to see vaccumm).
@@Realboostedbikes PCV is just connected to the tps so fueling is based on that. What about cruising with different loads on the engine? afr will be different every time. Isn't there a better solution like replacing the map sensor with one that can handle boost and tune via that like cars?
@oom4539 it's not as much of an issue as you qould think because you tune for different throttle positions as well. It may be a hair rich in lower gears but I'm running thus style setup on a few bikes with no issues. Just have to be on point with the tuning.
Do you have any tips on timing retard? Now i take of 8 degree on 12 psi. Maybee This is a bit exaggerated. I run stock comp 12.7:1 run european 98octane same as 93 ron. But i think i loose hp by having that mutch. The bike start building boost at 3450rmp. i run stock gas regulator. The bike is fast But not scary fast. I had to give it 80% more petrol on 12 psi to Get the afr target to 11.5 i have a slightly bigger injector. Do you think i need 80% because i dont have fuel pressure regulator?
8 degrees is way too much you're gonna cook your exhaust valve with that. I'm running stock timing on the gasgas they are conservative out of the box. You don't want to retard timing more than 3 degrees even if you're running 20lbs of boost. The more you retard timing the more heat you're sending out of the exhaust from fuel not properly being burned. You're gonna loose a ton of power too. You're better off running 8psi of boost at stock timing than 12lbs with the ignition retarded 8 degrees. It will actually live longer and make more power
I'm not running a rising rate fuel pressure regulator. I did upgrade to a 4 bar fuel pressure regulator which I tweaked to run around 4.2 bar. Upping the fuel pressure will allow you to use less Injector. 80% duty cycle is kinda pushing it imo you're at the limit
@@Realboostedbikes ok thank you for tips. I am just afraid of engine knocking, Since i run pump gas on stock compression ratio. 12.7:1 I have not seen higher egt temp then 680 celsius. But i will take away som retard and see how it behaves.
@@Realboostedbikes i bought a regulator today. I dont think i can adjust the regulator on the 690. It’s not possible to open it. I can cut it open and put in shims og Maybee stretch the spring. But then i have to weld it togheter again. So i’am planning to blind the orginal regulator and run a turbosmart regulator. I wish i was Your neighbor. I whould love to pick Your brain. This is my first turbo build so i’am kinda Learning på doing.

80 to the wheel, that'll be over 90 at the crank. Hell yeah!

Awesome!!! I really wish that Jeff was there just so we could see his genuine response to this modern power!! Nice work!!
Sweet build mate. You are a wizard.
That small piece of filter foam is going to be pretty restrictive you need a larger filter element I think

Working on a rotary exhaust valve to keep the boost in the engine. That's the biggest concern and why little benefit is had with current setups.
Awesome! Happy to see this channel pop up. Watch Kaplan all the time! Well done with your expertise!
Wish I could find someone like you to make a turbo kit for my Polaris RZR570.
Awesome job! Super cool build. Imagine that on a 690 enduro R!!
I am doing it on a 2019 690

The KTM 390 duke is a good candidate for a turbo. Solid ”one piece” crank.
Highflow 4-valve head.
Check it out.
Would be a cool bike to turbo 👍
Gas Gas needs more gas⛽️ 😊 how ironic. Well done Justin.
AWSOME build.
Would love to see you put a oil cooler on , how you would do it
I've been thinking of put a oil cooler on my 500EXC
Unfortunately that would hinder reliability and wouldn't add much benefit.
@@Realboostedbikes Ok , i was thinking it will help with rebility because the oil in dirt bikes gets hot and now a turbo it will go to the extre?

"...the brightest candle doesn't always burn the longest..."
This bike is designed to last as long or longer than a standard 450 engine out of the box.
Wow thanks for sharing all the tech and setup info ! Very impressive!! Ever done a 2 stroke 500cc turbo?
Not yet, working on a rotary valve system for the exhaust
Good call on the tire.
80 hp.
Dry weight?
Yikes!
I'm no wrench, you're talking over my head. I think it would break my wrists.
under 250lbs

But when will you ever need that much power

Snowbike anyone?
Когда будет заезд , демонстрация и тест-драйв?
Drop a few teeth on the back and it will make more boost and more power
Is it just me? .. but on the RHS going into the turbo is a tiny air filter right at the point where there's gonna be a heap of either dust or mud, and where you're gonna kick it with your boot?
No it's about the size of a bigger 2 stroke pipe. Completely out if the way or your foot or knee.
Ya know it’s cool and all, but I feel it would be totally useless on a moto track
The 450’s have plenty of power I find myself looking to tame them more than asking for more out of them.
awesome
Let's see you ride it on the track now
Cool build! Do you have stock internals in the motor?
Yes but they are massaged so nothing binds at double the power. Check out pt.1 to see what I did to the engine
120 hp is the record so far, set by a yahmaha 450
That same yamaha made 70hp at 8lbs of boost. Mine made 82hp at 7lbs
That means someone has to up the ante in the zabel(a Dutch guy got 100🐎)so ,.......work for the boss😁
Do you have a link to the gentlemen who made 100hp?
Husqvarna fc 450 93 hp
