Yamaha RS Vector Turbo + NOS + Meth..? Some questions.

[Yamaha_nisse]

Hi guys,

In the middle of completing my project for this winter.
Starting this thread because I have some concerns how to build my engine!

Setup ATM is;

Vector STOCK eninge with MCX head schim. Think its 3 or 4 mm.
Mid mount GT2860RS turbo, without oil pump (will it work).

I take the oil from the head (from the left side of the carbs)
And return down to MAG cover. Or do I need an oilpump?

Modifed MCX IC

TAIL 50mm BOV
1.1bar ~16psi @ 2000-3000feet
Boondocker dry nos with 30HP nozzle

--------------------------------------------------

Two questions:

Can it be driven on premium (is some were in between your premium and avgas) or E85..?

Would you recommend to use meth/water injection...?

Oil pump

My setup is going to be much like yours. I am slowly getting it done.

I am not planning to run a return pump for the oil. It should be ok to drain back. Just make sure to use a 1/2 ID hose.

I am going to be running a coolingmist meth injection system. Without a head shim and thinking about running 12-14lbs of boost at 8000+ ft.

From what I have read you should be able to run 12-13lbs with the head shim on 91 octane. The nos your gonna spray may change that though.

Where are you located. I am excited to see another vector project. Not alot of them around getting redone still.

Thanks for the input!

I'm located in Sweden, so its probably a bit far to go

I'm looking to break 250HP in somehow. Have some dyno sheets of it making 217HP @ 14PSI.

With meth, and some more boost around 17-18 maybe I'll get around 240?!

Does Meth and E85 work togehter?

How does head porting work out on a turbo vector?

Still dealing about my Nytro injection system, hope to close the deal soon!

Across the pond

Sweden, No be deal that must be only 4000+ miles away, lol.

Here is what I know. The vector motor was not given a oil pump that will keep the rods happy at higher boost levels. I was told by powderlites to go to a nytro oil pump. I saw that hurricane performance was making like 319 hp with meth at like 14lbs of boost on a nytro. I am sure that the head porting that they do plays a large role into the hp numbers. Either way the nytro motor is the vectors big brother. Alot of similarity's. I believe the cams are quite a bit more agressive on the nytro motor though.

I don't believe that water meth will give you a huge hp increase at the same boost level, It will keep your motor from heat soaking though. Also being able to turn up the boost at the same fuel quality.

If you want to get into the motor you can go with carillo rods, and low compression pistons. I believe you will make more power with the LC pistons because your squish is maintained and that is important in making power. Also head porting.

I think 250 hp is attainable on pump, with meth. I have read claims of 240 hp at 14lbs of boost. Also simons cpr claimed 195 hp at 7.5lbs. At that it is making right at 10hp/lb of boost. So one would stand to reason that you should make 260 hp at 14 lbs.

Was that 217hk or 217 hp that your sled was making. I know they measure that different over there?

Thanks for the input (again)

Never thought about the oil pump, may the nytro pump fit by any chance?! Or is there some how to get around that problem?

Why I was thinking water/meth is to turn the boost up but still run at pump gas.

Thanks Rasmus

Oil pump/meth/water

I do believe that the nytro oil pump will fit. Once the oiling is taken care of I would think you could run up to 18lbs of boost in the vector motor on stock rods, as long as you kept the denotation under control. With the head shim, and meth/water injection you could probally do that 18lbs. The 2860 should be still well sized and able to move enough air as well. Also I was recommended by a great engine builder to run a heavier weight oil. Try like a mobil 1 10w45, or joe gibbs racing oil. To give a bit more cushion for the rods.

I would reccomend hurricane performance for your meth kit. He will give you the support if you need it and has been extensive testing on snowmobiles. Not who i bought from but I bought my setup before i knew about him.

With all that I think it can get you to your goal. Hopefully you will post some more pictures of your sled as well.

I know the alpine kits are puttint out some big HP #'s. not sure what that kit comes with for a oil pump tho??? I do run 17-19 lbs on big play days with it. (chute climbs and drag races). no problems yet with almost 4000 km's

 

[johnny be bad]

this started as a 2008 vector gt. alpine front mount, runs around 15-16lbs of boost. sleds a total rocket.

 

[Yamaha_nisse]

Nice sled there!

Thinking of building me an apex look aswell, but the engine and skid is prior as for now.

Looked up the oilpump - seems to be almost the same (will fit).

Also found out, there's a lot of parts from the nytro that WILL fit Vector, but are not that pricey.

More inputs are welcome.

So, you think its possible to reach 18# of boost with a Nytro oil pump, Meth/water injection and MCX head shim?

Thanks Rasmus

Been running 13psi on a MCX kit for 2k miles on pump gas with no problems. Installed a boost controller this season and going to run up to 17psi with a 50/50 mix of race fuel for fun. Never heard any detonation @ 13psi and figure I'm probably good up to 15psi with my head shim and pump gas @ 7000ft and up. Glad to see over Vector riders are out there!

Cam timing

Also forgot to mention cam timing. Set the lobe centers at 112-114 degree on booth intake and exhaust. I know that mcxpress does change the cam timing for the head shim but I think they jus change it back to stock.

this started as a 2008 vector gt. alpine front mount, runs around 15-16lbs of boost. sleds a total rocket.

Hope that oil breather works better than the old ones. they leak constantly.
nice lookinf sled tho.

Turboyammi;

Mine has been running @ 15-15.5psi all last year at sea level on premium.


-------------------------------

Still no one to confirm the nytro oilpump question? Not an expensive mod though.
Would be great with some more input.

How about nytro camshafts on the vector?
Retard the ignition? Head porting?

But as you put it, its the lubrication for the rods which is the biggest problem @ higher boost #?

 

[Turbo11T]

oil pump

I was told to use the nytro oil pump from powderlites. I would guess since they told me this that it will bolt right up.

Also interested to know if the nytro cams would be another option?

Also possibly you could gas port the pistons as well.

 

[Yamaha_nisse]

OK,

I'll order an Nytro pump then. What's the difference between them? More flow, higher pressure?

Nytro cams isn't an expensive mod either!
Under 200$ u could get a pair of used ones.

Thanks Rasmus
