Racer X turbo build

[Racer x]

Two fifty ninja power !!

[choneofakind]

Looking good Eric. I bet you're making Matt's day, documenting the turbo install with the fuel injection.

[Racer x]

I hope so.

[mgentz]

Do you run stronger rods? Better clearance for oil flow?

[Racer x]

No. I am just going to use the same motor I use for nitrous. Just with lower compression. I will be building two motors for the turbo. Both 265 cc. And I am hoping to get a 300 engine.

[TonyKZ1]

So when are you going to start building turbo street engines for the rest of us???

Just Kidding! But it sounds like it could be a lot of fun on the street. Keep up the good work and thanks for keeping us updated with your progress.

The hot side of the turbo ia about done. And I got a Major jump on the wiring.

[Racer x]

I made a mock up of the plenum. Now I have to draw a picture of it and make all the measurements. There will be a blow off valve above the engine. And the intercooler in front.
I made the mock up from sheet aluminum and tape. Now I send this to Dave Huntress. www.tanksbytigman.com he will make the real thing with fittings and mounting tabs .

[choneofakind]

We doing a little ram air? haha

[Racer x]

I need to fab the intercooler. But really I need to have it made and fab the rest around it.

[Racer x]

The next step is the lubrication system for the turbo. And I need help with this one.

Bprayogo has been a huge help with information. If you look on the bottom of the engine there is a big filter housing. Next to it is a drain plug. On the other side is a fitting. That fitting is to test oil pressure. Bprayogo suggested using that as the feed line . And returning the oil to a fitting in the crank case that is above the oil level. And of corse I would have to add that fitting.

I have the turbo mounted as high as I can and it is above the oil level. If it is mounted below the oil level. It will not drain properly and it will smoke.

So first I have to double check the turbo placement .

Then figure out the fittings to run the oil. This is not as simple as it seems.

The turbo requires .05~7 psi oil pressure. And 15 gph

The engine oil pressure is 14~21 psi and I will raise that some.

So to achieve 1~2 psi. in the turbo I have to have a restriction at the inlet. That will set the volume. Then a restriction in the outlet. That will set pressure.

For inlet I will use 1/8 npt to 4an with 1/4 inch hose. And the outlet will be 3/8 npt to 8 an using 5/16 hose. I will rig up some sort of gauge to test this.

[Dark]

The oil setup for the turbo WR250x system I ran used a standard nitrous jet to restrict the oil pressure to the turbo.

Hey Racer X.... Great job on the build so far!!!

I have been around bikes for quite some time and I have been big into the ZX-10r's for a while but I have been toying around the idea to get into some Land Speed Racing on a budget and have been thinking about trying to get a 250 together for the Ohio mile in September along with my 300hp Turbo busa lol.... Going to try to get into the 220mph range with her... current record is 226in the mile in the MPS/BF-1350 class so I'd have to beat that to take the title for now...

Anyways very interesting to see your turbo build!!! I was thinking about doing the same thing with nearly the same parts.... what do you think of the ecotrons FI kit so far? Does it seem like a solid piece of equipment?

Don't worry I think your way ahead of me on any kind of 250 LSR build but I may want to get into it eventually lol.

Another quick question if you dont mind.... what kind of injector style are they running in the throttle body, they looked kind of weird int he pictures, do you have any pictures of the injectors by them selves?

P.S. as far as oil feed my turbo busa has a line coming right off the side of the motor that suzuki uses to test oil pressure.... If you check in the kawi service manual it should show you were to test oil pressure and you should be able to find a fitting that you can convert over to an AN fitting.

IF you need any info about turbo bikes hit me up, I have a quite a bit of knowledge with them :-)

Good luck with the project!!!!!!

Sorry one more thing... I see you have a LSR front fender.... have you looked into any that cover more of the wheel? Like maybe using a busa front fender or something? I ran a busa fender on my ZX-10r and picked up some mph

[Racer x]

Hey great to hear you are coming to Ohio. Bad news is Randome Holbrook just went 230 with apparent ease. So build for 245. There are no real 250 records yet. I am only running 350 for now. Then next year look out.

250 nitrous bike with real engine. And this turbo testing for Bonneville should put up some nice numbers.
I can sure use help. I post up everything. Please let me know when I am going wrong.

Damn, where did they do that 230 at? Ohio? I didnt see it in any of their logs or records pages? Maybe they are slow to update them?

I honeslty just want to go over 200 a few times and I'll be happy with the turbo busa lol.

Yeah I may find myself getting into the 250 stuff, a buddy of mine really wants to get into it and hes small... I'm about 6'1" 230lbs so that might not be a good class for me to run it lol.... but hes about 5'6" 130lbs so I'm sure he would do just fine!

Have you tested the wastegate to see whats the least pressure you can run?

What compression changes do you have in mind for the turbo build...

[Racer x]

To answer you first questions
. My injectors are 190 gph for Etron and the throttle body is the 250 ninja unit from Etron. Everything I have so far is very good. The wiring is very nice. I am building this bike for salt. So weather proofing is a big deal.

Ransom just ran 230 mph at Ohioin July.

The 250 is a lot of fun. I am 6foot and 185
Lb. lots of work to get the tuck worked out.

This engine will have about 9 to1 maybe higher. I am going to be racing at over 5000 feet. And once I get .5 bar sorted I will run 1 bar of boost. I have not checked the waist gate. But I will check everything.

Very cool, how are you planning on lowering compression? I havnt found anyone with low compression pistons just yet. Base of head gasket?

I was thinking of contacting Cometic, they can make copper spacers very easily.

Yeah if you get a chance I'd like to know whats the base psi those wastegates open at.

Glad to hear the ecotrons stuff looks decent.

Have you thought about running E85 instead of intercooling??? I picked up 30hp switching from 93 to E85 on my turbo busa att he SAME boost :-) lowered my running temps and bike performs great. Might be a way to simplify your turbo system. Check into it, there are a lot of people with big hp cars and bikes that are doing this and having no issues.

Now the Ecotros software (I have a copy and a map for a 250) you can control timing.... this will be amazing for us as you can simply pull a tad bit of timing out with boost but on my 300hp busa... I'm running stock timing with a .080" spacer plate on stock pistons and have ZERO detonation issues and the temps are all within spec! For LSR I'll probably pull 1-2 degrees just to be on the safe side but I'll also be running E85R so I may not need to.

[Racer x]

I am planning to use e 85 and nitrous. With an intercooler. But I have to really watch temps. I am going for 100 HP

But I must go one step at a time.

JE will make pistons and I have connections with Wasner. If you want thick copper head gaskets. I have already paid the R&D charge at copper head gaskets . Com

[garth285]

Why not let the turbo do all the work?

[Racer x]

I will start with the turbo on race gas. Like c 16. See how that goes. If the turbo makes 60-70 then I will just add enough nitrous to get 100 HP. If I have any trouble with temps I can then go to E 85.
I don't think I can do it with just a turbo. And I would need more nitrous than I can carry. The turbo will act as a one way pump when I add the nitrous.
I use the Wizards of nitrous. The system will all work off the O2 sensors. Should be fun to see it all work.

Very cool, now the O2 sensors your talking about are the ones from Ecotron right? Those are narrow band o2's are you going to wire in your own wideband to get a more accurate reading?

[Racer x]

No the wide band sensors are two expensive to fry. For what I do I think I can get ways with a ore written map. At least until I get to the edge. For now I just want simple safe and functional. I will rebuild it every winter once I get it going.

[garth285]

Hmmm, well since your running turbo you could always just wire in one wideband after the turbo?

[Racer x]

Ya I will see how it goes. I am a bit away from that yet. But I could always switch later. I had wide band on my nitrous bike. Two sensors at 80 dollars hurts. I switched to EGT for that bike.

Smart idea.... I saw a nice 4 channel EGT set up a long time ago but it was expensive, was going to run it on my older ZX-10r but never got it.

Have you found any place that sells one for a reasonable price?

[Racer x]

Check out this video on YouTube: this is my nitrous bike.

http://youtu.be/wY0z_HkTTmo

The gauges on the bottom are Made by Koso same as the dash. They work really well. I have the high speed sensors.
The unit display shows the EGT in Blue. I have it set to turn red at 1000 deg. With nitrous u hit 1200-1300 deg. So both sides should turn red as soon as the nitrous hits. If one side goes cold I know I am done. Works great.

[garth285]

Oh wow that looks cool!

Maybe I'll run a single one on the turbo busa to watch my EGT's

Just got my wheels and race tail section in for the turbo busa... debating on starting the turbo 250 project just yet..... may have to wait until next year but depends on if I can find a good deal!

[garth285]

E85 will help out with your EGT's a lot to once you get it dialed in.

By the way you may find yourself running out of injector with the injectors you have with E85 and turbo.

Heres a good calculator for ya maybe? http://fuelinjectorclinic.com/flow-calculator

I think I used this with my turbo bike, I wound up getting 550cc injectors and I'm running spot on.

[Racer x]

The volume is why I am building the system with very large fuel fittings. I can go to 235 gph from 190gph. That should do it.

[garth285]

Awesome good deal!

I almost had a great deal on a ninja 500 for a LSR bike but I want to stick with the 250 and boost her :-)

[Racer x]

Please do.
I have been carrying the torch for the 250 ninja since 2008. We need to fill up the record book with some strong 250 records.

Forget the 500. I am about as fast as the modified 500s that show up. AND some people take a Yamaha 400 top end and bolt it to a 600 bottom end. Makes a 499 cc bike that hits 140 mph. Other guys take the 600 and remove one piston all together. Those are running close to that speed. The best I think a 500 went was 127

[garth285]

I have been on the hunt for 250's like crazy, I'd love a 08+ but dont know how much $ I can put towards the project along with the busa lol.... I can pick up the older 250's pretty cheap but I think the aero's of the new bike will help out

[Racer x]

The first gen bikes have a faster top speed. But I don't like rocker arms. Both bikes are great. This turbo bike is a 2001 frame . But the rest is 09 or 10.

Yeah same here, I dont like rocker's.... I'd up the RPM's a little more with the turbo I'm sure to... might have to be an older 250 though for starters....

While I have you hear what years do they call gen's for the 250's ?

Sorry. No turbo for me. Sweet looking build though. So jealous. ..

[garth285]

Hey Racer X..... have you tried running two intake cams? Was checking the service manual and looks like the intake is a lil larger than the exhaust on the 08+'s

[mgentz]

2 intakes is the cheap ticket to power. X runs it currently I believe.

My bike also runs two cams of the same profile.

[garth285]

Nice, has anyone dyno'ed the difference? Anyone make adjustable cam sprockets or are people just having the stockers slotted?

[mgentz]

Ape race parts makes slotted sprockets.

[Racer x]

When I changed to two intake cams. I jumped seven HP on spray. Made no NA difference. But I have not really explored that yet.
I have adjustable cam sprockets. I don't use them though.

86-87 are old pre gen
88-07 pre gen
08-13 new gen
The 300 is the 300. These titles change over time.
