I suspect because there is a bigass catalytic converter in there. Don't need two and they're not cheap. Just my thought.Anyone know why the turbo kit's only come with a single muffler? Is it due to cost only?
I prefer the dual muffler set up to deepen the tone of the exhaust.
Who are you talking to over there; Josh? I don't know if the redesigns are for the next version or what but they have 100 units damn near ready to ship. At least that's what my conversation covered. A change in the can angle and more R&D on radiator does not sound like units going out next week.What you see is pre production fab. I have talked with MPI and they are working on changing exhuaust. I don't think dual exhaust will change sound too much with turbo. Turbo's naturally quiet things down. I thought the same about air charge cooler. In their tests they video machine from rear. There is a natural down draft and with fan blowing across air charge cooler, they got good results in lowering air temp. I don't think there will be any problem with the engine handling the turbo's power. I think 300 HP is a cake walk for this engine. Have several Yamaha Apex snowmobile's range in horse power from 300 to 550. My trail sled has 4000 miles on it and makes 400 HP. No engine failures on any of them. Engines are really tough. I think getting rid of heat will be biggest challenge. MPI's test is a run up a switch back road. Start out at 4000 elevation and climb to 10,000. Running 155 HP with 6 lbs boost. Halfway up engine temps were at 238. (running hard). They are working on that problem now. Possible new or different radiator or placement.
Guess you have never seen some LS turbo cars with the turbo remote mounted in the rear. I can tell you they are no slouches. Is it ideal? Probably not but it really doesn't make much difference at all with power delivery. Saw the Weller prototype with the turbo hanging right off at the collector with a short manifold.anyway you slice it if this kit is over 2k dont bother, you want to make it efficient? that turbo needs to be right up next to the exhaust flange not 42" away! If you're going to tool up do it right....and its a totally different game with longevity and power numbers once you come down off the mountain elevations....these motors really need lower compression pistons to do it right....my two cents....
Yes I talked with Josh. Not sure how much different muffler will be but he said what you saw is pre production. I think I will wait for higher boost and lower compression. If im going to spend money on a turbo, I want to make it worth while. I have a Pace Wildcat and at 300 they rip. Not that they don't at lower settings. I agree with keeping turbo mounted close to head. What I will say is on the Apex there is no lag. Not sure what kind of issues there may be with shifting vs CVT when it comes to spooling. I have had small turbos on my Apex. 2554 and my largest is a 3076 on a different sled. No lag on either but you hit your RPM's quickly and hold it there. I have 1 engine with head shim and 2 with pistons to lower compression. Have had good success with both. Best performance I see is larger turbo and running at lower boost, lets you get away with pump gas. In the middle of changing turbo onn Wildcat, going to Evolution Turbo, Hope to see 300 HP on pump gas or close to it.Who are you talking to over there; Josh?
