Well after getting a new header from Need for Speed/ kevin E. Getting to finally get to work on the sled. Got her tore down, again, tonight and rough fitted every thing while I wait for gaskets.
Right now I have to modify the down pipe, nothing big. just have to cut the flange off and change the angle a few degrees. Trying to get her done for this weekend but we will see, I am not holding my breath on that one.
Just getting everything on and tested, then full tear down and send everything out to get swain tech coated and different exhaust for next year. Along with powderlites stage 3 Intercooler, and bigger injectors. New hood, and modified air intake.
And finally getting rid of the POS speed track for something that will bite better in the snow.
heres some pics

Got her all fabbed up and bolting everything down. Worked on some RB3 maps and we are getting there, should be ready to test this weekend.
The only hiccup now is, I didn't have the typical wastegate rod hitting the fuel tank issue, after the install of everything it sits right on the rod, I am going to rivet an alum guide off the steering gate right above the WG rod to push the tank over the 1/4 inch I need. That should work Fine.
Also I re did all the heat shielding on the fuel tank and put in a 90 degree piece of aluminum along the edge of the tank where the rod could possibly hit.
Got the down pipe rewelded and have plenty of room now. Just had to cut back and bend the tube under the tunnel to match the new placement on the down pipe.
One thing I can say though, is I put my CPR header on twice on this sled, and did my old mans Powderlites header bolts on his sled. This 4 tube header took about 5 mins to install and have turbo mounted. !/4 drive with a swivel socket and didn't even have time to drink a half a beer.

Well got her all back together and finished up. I didn't get to take any pics of the bracket I made off the steering gate to hold the tank off the wastegate rod, but when I tear down again I will post it. It worked out perfect, I now have about 1/4 inch clearance.
The only thing that come close is the steering arm comes real close to hitting the header, It does hit the heat shield right before it stops out. Nothing serious though.
Also to to modify the heat shielding for the bigger header. Nothing to bad just some new bends and some new rivets.
and I added Jannetty Water hose and fitting kit to the turbo, Hopefully I will stop melting coolant hoses.
There is plenty of room between the gas tank and down pipe. And I installed 3 layers of the heat/fiberglass stuff through out the whole area.
Put her up on a stand and ran it through the RPM range. A/Fs are still a little rich but I will wait to make final reading Friday when I run it on the lake. I did notice quickly that the response is faster. Just sitting there blipping the gas it revs smoother and quicker. Also holding RPM 4-5000, it jumps up faster as well.
Just quick observations. I will hold back final opinion till I put a load on her and drive it.
Leaving Thursday Night and will have A good idea of the gains with the new header and RB3 mapping.
I am lucky enough to have a similar sled to test against. My dads Powderlites attak, is basically the same set up as my sled. The only differances are I have a CPR intercooler, and My air intake is under the stock head light and I run a full 136" xpert x, and he runs a 121 xpert x that is set back to make up the difference.
Everything else is Identical. same track, same pics, same gearing, same RB3 map, close to the same clutching, you get the point.
And in the end, before the changes, his sled runs 10 lbs boost and I run 12lbs boost. I would leave him a sled length or 1.5 sleds out of the hole. Then by 600' he would catch me, and by 1000' he would be 1-2 in the lead. We did this race on snow, Ice, roads, fluff, Hardpack, etc.etc. and same results.
So this is good before and after comparison. We will see.
Sorry for the long winded post!!!

Got back last night from running the sled on sat on Big Moose Lake.
I didn't bring any clutching stuff with me so I ran the same set up I had. With my set up, I was pulling 10200 and traction was good. Real soft Ice and not much track spin, I was running 91 grams could have pulled 2 grams out to get closer to ideal RPM.
Well once I got the RB3 map pretty close, I had to add fuel across the board to get from being to lean, so that shows I am flowing more air with the 4 tube header. Now I was running 11.8 @ WOT and 12 at cruse and 12 @ Idle. still can tweak that but it was good for the 38 degree day.
Once I got that in I played between 2 different timing maps on the RB3 as well. The sled ended up liking the map I had with 3-4 degrees added in the lower RPM/load ranges and had 2-3 degrees pulled out on boost and higher RPM range. She just felt nice and didn't pop and had real good throttle response.
At the same time we got dads sled going and did a few test runs and we decided a rolling start on the race would be better to test what gains the header would give. Due to my clutching is more aggressive and I always pulled him out of the hole, so to test and see we took the hole shot out of the equation.
Plus I set my boost down to 10-11 lbs. It would peak to 11.5 but hold around 10.5 Same boost as my dads sled.
So from a rolling start on good Ice, The first hit we would stay close but after 100 feet My sled would start to walk away. By the 1000 foot mark I would be 1-2 sled lengths in front. We did this for 3-4 runs to make sure it was consistant results.
So in the end this Header is very good gains. Not only did I gain the 2 sled length loss but I put another 2 lengths on him, and all this on 1-2lbs. lower boost. Plus I did notice that midrange/trail speeds the throttle response/spool time is quicker.
I now wish I brought the clutching stuff to get on the RPM better and the gains would have been bigger.
Kevin, Great header, it did close to what you said it would and I know with more tuning, fuel mapping and clutching it will get better and probably do exactly what you said it would. Thank you!!!
Getting the header to fit needed some changes but well worth it for the gains.
Ted J. water lines work like a charm, finally a weekend I did have to replace antifreeze lines. Thank you!!!

Thank God for my son,s knowledge with the RB3 (you to Ted) he has almost got the mapping down perfect ,we had an issue with the lap top down on the lake, remapped my sled and got it straightened out ,had made some changes and was running dead lean but was able to get it right.
Had I been left to my own devices (with the computer) somebody would have had a free Apex as long as they pulled it out of the lake

will do ted...you run that skidoo header yet??
here we go again, a long summer of modifications, After looking at RXriders post about using a rev tank I figured I would give it a whirl. I found a ski doo XP seat and tank. 10.6 gallons of fuel and good placement.
Got her rough fitted and I think i will work great. Just have to change exhaust, and move the mounting bolts and fab up some brackets to mount the tank and side panels. Then I am thinking some black neoprene to fill in the front of the seat down to the side panels.
All this and there is tons of room around the header/turbo now. Enough room for a mid mount turbo.....HHHHMMMMMM

plus without fuel, its about 10-15lbs lighter.!!!
any one have ideas on what else to cover in front of the seat, and or Exhaust???

Cut the tunnel up in pieces today and fitted the tank to the cowling, had to make some cuts, and move the tank more forward then I wanted to. I wanted the fill to be centered in the same cowling hole, but didn't have the room. So about 2-3 inches forward it went, Now I just have to get some plastic and make a plate to cover the old hole.
Trimmed down the side plates and they will work fine...
Getting the tunnel piece bent up on Monday to still give room for the exhaust to go in same place for out the back muffler. Might have to go with two 1" 1/4" pipes instead of the single 2.5 pipe that was there. That is going to make muffler selection real fun.
If any one has some input on this or different Ideas let me know... please...
Also going to change the back of the tunnel a little, maybe do some diamond plate like my old mans sled, But I will paint it black, to much polishing is not fun....

Looking good aja636
This seat tank combo is alot more comfortable to boot.. Seat hight is about 2 inches taller and not as soft.
Got my new tunnel piece today, quick call to a friend last night and he bent it up this morning.
Being a boat builder, it is great having friends in the fab world with all the fancy tools and material laying around!!
right now it is still a little long but we are bending up the side plates tomorrow and some added pieces for strength. After that I will decide where to cut her down to. Never know I may have a 144 proline under this some day....??
Should have her ready to rivet up over the weekend, and got my new exhaust stuff coming.
Ted Jannetty hooked me up with pipe and a turbo flange, I got something special for exhaust since it will not fit under the tunnel.

Well Lads, this is the typical putting a prom dress on a pig, you still ain,t going to beat the old man LOL
