47. Dress the hole edges with a file to remove any sharp edges.
Vacuum up and blow-away any chips and filings.

48. Cut 3 small pieces of Rubber Edge Trim to fit the bulkhead.
We recommend gluing them in place with a 3M Gasket & Weather Strip Adhesive Glue or similar.
See Figure 27C.

At this point I realized I had made a mistake.
I installed the rubber insulation on the LH side as well as the RH side.
Looks like that was NOT necessary, so I will probably be removing it from the RH.....

Cut and test fit the 3 strips

Glued and clamped just like before.

49. Remove the radiator overflow mounting tab from the black tubular cross-member.
Dress all sharp edges
See Figure 28.

Out comes the grinder and away goes the tab!

The tab is GONE.

50. Install the grey hose (14mm; that went from the air box to the top of the oil tank) onto the oil return barb on the front of the engine just below the billet water manifold.
Use an OEM spring clamp.
See Figure 29.

Ran into a problem here.
I installed the OFT Rollover kit on my Sled.
This valve ended up in exactly the wrong position to be able to reuse the grey hose. So I had to use some regular none formed hose instead.

So far it "appears" that standard hose will work OK.

I removed and reused the protective sleeve from the original hose.

51. Install the water thermostat with the 3 hoses still attached.
Use the OEM worm clamp to connect the short hose to the billet water manifold.
Note: the 8.5” ¼ carb heater hose goes all the back next to the case.
See Figure 30.

NOTE:
During my prep I removed ALL of the hoses from the thermostat housing so I could torch off the nipple with greater ease. Now all of them have to be reattached.

52. Connect the bottom thermostat hose to the lower heat exchanger outlet with an OEM spring clamp.
Install the supplied #24 (1-½”) rubber coated Adel clamp around the lower thermostat hose and secure it under the upper most M8 chaincase cover bolt.
See Figure 31.

RH side ready to re-attach the lower cooling hose.

Hose attaches and fits perfectly once again.

But now the hose will be secured to the chaincase cover.

ONE CONCERN I have at this point.

As it stands right now, the thermostat housing is sitting up tight against the RH frame of the sled.

This just doesn't seem like a good idea.

So I am thinking I may disconnect the short hose between the Thermostat and the manifold the SHORTEN it a bit to relieve some of the pressure that is pushing the thermostat housing into the frame.

Seems to me I could take a Half-Inch or so off of that hose as it just seems too long now.

Anyone else that has been down this road have any comments to offer??

christopher · Aug 21, 2011

If no one is going to offer up a good reason NOT to trim that hose and move the thermostat back away from the frame, then I think I will go ahead and cut it.

Obviously I haven't been down that road as far as putting an SC on a sled but been there many times on autos. Your not going to hurt anything by trimming that hose, just trim a little at a time until you get enough clearance to make you feel comfy. Actually, the way it looks from your pic, it needs to be trimmed - notice how it wrinkles.

christopher · Aug 21, 2011

It certainly doesn't look like a good clean fit to me.

Looks like you are doing a great job Christopher. Keep up the good work.

christopher · Aug 21, 2011

Slow but steady.
The supercharger itself goes in next!!

The tab that held on the water tank needs to be trimmed perfectly flush with the cross tube on the subframe. If not, when putting intercooler in it can scratch, or catch a cooling fin and cause damage. Also during riding, motor flex can cause it to rub if not flush with cross tube.I also like to smooth out the support tab on that side that comes down from the shock bolt mount to give just a hair extra space on the backside for the intercooler to slide in and movement of the chassis.

TRUEBLUEMAX · Aug 22, 2011

Isn't the hole that you drilled on the clutch side for the cold air intake? Just wondering because I don't think all of the kits come with that do they? I just thought if they don't maybe you would want to point that out so that people that don't have the cold air setup wouldn't wonder what you were doing there. Just a thought.

Bit late on this but that spanner wrench looks exactly like the tool that comes with a grinder to change wheels

Thanks for the insights!
I will go back down and grind that tab 100% of the way GONE.

And grind off a bit of the Shock bolt mount as well.

I know they sell the Cold Air Intake as an option.
But when the State 1 kit arrived that was part of it.
And in the instruction manual it makes no mention of that being an optional step, so I am guessing that it is now included in the kits??

Yup.
The only issue is if it just happens to be the right size or not.

That is probably a good thing. I know one of the big battles the supers have is underhood heat. It really should be standard on that kit.

Went back in and trimmed that hose.

Removed about a half an inch of hose.
Fits much better now and isn't pressed up hard against the frame anymore.

SUPERCHARGER INSTALL

53. Slide the supercharger part way into the sled. See Figure 32.

54. While looking at the inlet to the supercharger rotate the unit
counterclockwise a little. See Figure 33.

55. Now slide the supercharger further in as you rotate the unit back clockwise. See Figure 34 & 35.

56. Bolt the supercharger into place using two M8x25 flange head bolts (provided) on the top, a M8x35 flange head bolt in the front lower hole and a M8x40 flange head bolt in the rear lower hole (provided & used earlier on the template) on the bottom (note: at the end of the project you will have 2 extra M8x40 bolt left over – used on template). See Figure 36.

This is a TIGHT FIT, and you really do have to "Wiggle" it around a bit to get it to drop into place.

That electrical harness line had to be moved before the SuperCharger would drop in.

First try at getting it through the hole.
And yes, I had to remove all of the rubber insulation that I had previous installed on accident.

ALL of the hoses fit VERY tightly.
I had to go back in and twist the Hose Clamps to a different position so they wouldn't rub on the other hoses.

I also had to move the thermostat house backwards a good inch or so for the supercharger to fit into place. This means I will likely go and trim 2-3 inches off the UPPER heat exchange hose as it is too long now.

The Supercharger is in place and the 4 bolts are in.

Just to show how far back the thermostat housing had to be moved.

The Final Result.
