Sea Level Trail Riding Low Boost Kit Questionaire

[Srxspec]

I'm judging interest here. Our low boost kit is already priced very affordable for most who want boost and can easily be upgraded down the road to any of our higher HP kits.

What I'm asking is who would be interested in a lower boost setup (5 lbs maximum boost) for pump gas trail riding (91 octane fuel). This kit would be much more costly to upgrade in the future.

The kit would include:

• 8.5 gallon Trail Tank specific to the turbo kit
  Cast iron manifold ceramic coated
  Cast iron down pipe ceramic coated
  Exhaust would go into the stock muffler
  Non-intercooled there would just be a plenum that attaches to the throttle bodies no intercooler
  Lower dollar, journal bearing turbo with ceramic coated turbine housing
  Power Commander PCV fueling
  Full heat shield blanket kit for the manifold, turbine housing, down pipe, and all oil & coolant lines going to the turbo

This kit would produce 170-175 hp on 91 octane pump fuel and be setup to run at sea level only. No boost gauge or air/fuel ratio gauge required. Your stock clutching arms would be reused with new rivets and a new primary spring and helix.

Pricing would be aimed at $3,499.99 and the kit would include all turbo components & hardware, clutching (rivets, spring, and helix), and a new top gear and chain for gearing.

If I'm going to pursue this I need a bunch of interest or 10 people to put a deposit down on a kit.

I know there will be questions on factory warranty like the Yamaha low boost kits offered for the higher elevation guys. The warranty offered with those kits is not a factory Yamaha warranty. All that warranty covers is any item that was not caused to fail by the extra power of the turbo/supercharger (say a bent subframe, etc). Any or all engine or turbo/supercharger broken parts are not covered by Yamaha on those kits, those failures will be handled by the turbo/supercharger manufacturers on a case by case basis.

So that warranty is not any better than having a good dealer who, more times than not, will be able to get any parts that were not damaged by a turbo/supercharger covered under the Yamaha warranty.

Yes, I'm interested, but a ittle late... If this would have been presented in the Spring of this year, I would have done it for this year. Also, what about guys with a PCIII, will you have a map for those?

On another Note, they also said that the MPI SuperChargers/Push Turbo's will Not be covered under Yamaha Extended Service Plan (YES), it only covered under the original 1 year warranty, which I thought is weird and un-characteristic of Yamaha.

Sounds like exactly what I want!!

Do you know what kind of MPG you can expect with this kit, how much of a drop over stock engine would you expect? Where I live there aren't alot of options for gassing up on the trail, and I would hate to have to depend on someone else for fuel.

PCIII guys the kit will cost the same. You will receive the Multi-Function Hub & Map Sensor to add to your PCIII.

I have several customers with our current Stage 1 kits that high speed trial run and if they are cruising 60-80mph through the trails they will average 12-14 mpg, not a whole lot different than stock.

You have a lot of room on the back of that xtx for fuel

darn good idea... I think you should make the turbo blanket an option with slightly lower base price...

also..for the guys who compare H.P. to H.p. of turbo to superchargers...you might want to show a few apples to apples dyno sheets...

 

[RIGIDONE]

anything for a phazer like this?????

I think this would be great, but could it be made to run on 87 octane...some places just don't sell 91 anymore. Is it possible to make a 5lb supercharger kit?

This is the problem I've been thinking about with my new sled. So I bought a case of Klotz octane boost. If I can't find 91 I'll just dump some of that in.

No omitting the turbo blanket system. I'd rather keep it included for a safety factor!

Turbo vs supercharger....it takes 2 lbs more boost on a supercharger to make the same HP as on a turbo. A turbo also makes more torque and has a much broader power band as well.

Sorry there just doesn't seem to be enough interest from the general Phazer guys.

With a electronic boost controller I could set it up to drop down to 2-3 lbs boost, need to do some testing with this, but I'm sure it could be done. If you ride it sensibly on that it should make it on 87 octane, this would be an add-on to the base kit.

I'm sure you could make a 5lbs supercharger kit if MPI or someone else wanted to. They'd need bigger pulleys to lower the boost down to 5 psi (which they currently don't have).

Interesting, I didn't realize the the turbo was that much better, thanks for posting the graph showing the difference. The only reason I would prefer to go supercharger is being able to go with the 10gal tank vs 8.5...while an extra gal is nice 3 would be even better...ecspecially know that with 170-175hp on tap, chances are it'll be needed lol. What would it take to get the MPI system Yamaha is offering to work at seas level...and on 87 or is it just not doable?

Allan,

How would this system work for the odd trip out west? Still work pretty good at 10,000 feet?

 

[**sj**]

al,

where the above two runs with a stock style or skinz muffler by chance?

maybe you can post some dyno charts on the stage 2 also..show the h.p. numbers if you can...think the guys need to see this as well...

You can gladly call MPI and ask them what it would take to make their system work at sea level on down to 87 octane. This is about a Ulmer Racing turbocharger so please do not hijack the post.

Allan,

I would strongly recommend against that. I just do not like the combination of 4 foot of powder on the hood and very little ground speed (no air flow) without an intercooler. At least the intercooler will help dissipate the heat.

The turbo sled had a Skinz muffler on it, supercharger sled had a stock muffler on it. That graph is 210 hp Stage 2 setup. The turbo was set at 7 lbs of boost and the supercharger was running 9 lbs of boost at 9,000 rpm.
