N/A performance compound??

[Norway]

Ok so many different performance enhancements have been made for the pro, but how to they compile? I know we cannot make a turbo-sled from small add-ons, but here is what I am after (and this would transfer to the Axys as well):

1. We soon got some lighter pistons that spooled quicker and vibrated less, then some longer ones + spacers.

2. The first year PAR sold a ton of heads + HPS cans for some nice gains.

3. The new lightweight crank and long rod crank has this thing running even better.

4. V-force reeds

5. Some ECU go-fast instructions, either reprogramming or full out Vi-pec.

6. Single pipes and some cans both loose weight and add power.


I would really like to hear from people who have mixed several of these enhancements!! Theories, not so interesting...

we have a porting package that we do, either a dyno port pipe and manifold or a slp pipe and can. porting done by us. v force reeds which do make a difference and a head. when you put all of this together you have a very strong running sled. we have not done anything but run stock pistons and stock crank so I am no help there.

Not quite the same sled, but my cousin has an SLP stage 3 kit on his Dragon and it's pretty impressive. It's a pipe/can, power dome heads, vforce3 reeds, high flow intake kit, power commander, and custom clutching. I plan on doing it to my new-to-me pro next summer. As far as performance upgrades go that's all I plan on doing. You could also do a stage 4 kit which adds porting, or the stage 5 which is the hillclimb race edition porting

SLP advertises 21hp over stock with the stage 4 kit

I run the rk tek drop in kit with head 13:1 put it in broke in and then started to dial it in. I was running the hps can but felt it restricted it as the drop ins like 8500rpm. Was a little better with stock can but not a lot of difference from stock.
Next I threw on the slp and can with pcV ran the stg 3 map as starting point.
3-400 rpm consistent.
Dialed clutching back in to 8500 and toyed with map a bit- never have auto tuned it as I didn't want to buff the ceramic coat to weld fitting in, no egts either. Just seat of pants and plug colour tune. So there's a bit left on table but has run 2 seasons.
I also spray it with boss noss 60hp shot
We ride at 2000ft and couple trips to mtns 6-7000ft
Flat land I rarely use juice but have racing this motor combo loves rpm.
Geared down 155 2.5 camo extreme 95mph @8800 rpm
Last season we had some good field drags
Tons of slight mod pros. Some etec , a silbur turbo
Buddy and I have exact sleds with mods and we were always out front every race 2-3lengths on motor only, with juice its 4-5
It has been a pull rope and go sled since building and that's what I like. Reliable only had one pcV issue when I broke ground tab off when smashed bumper in tree, un plugged the pcV and rode it for 2 days with no fuel controller in mtns. Was a little lean on long pulls and down low- but oh so crisp lol

Would not hesitate to run the drop in kit again but highly recommend the slp pipe and can pcV to get most out of it
