Matt, cant make every good topic a sticky... but we can add it to the list of great topics in THAT sticky.
Before the 900 people start wondering about it... the PRO steering will not work on that chassis... I've already looked into it in depth. The pitman arm/tube would be directly in line with the PTO side throttle body inlet.
On the IQ Small blocks... this steering would be great as the action is more natural with the steering post not "canted" to the side... you actully turn the bars rather than swinging them thru an arc...a much more intuitive/ergo way to ride...
The PRO chassis steering leaves the rider in basically the same fore/aft position
This is indeed one of the 3 main improvements in the Pro Chassis over the dragon
1) Sled width
2)Steering mechanism action
3)Rear suspension.
Sure there are other improvements such as weight and rigidity of the chassis.. but... IMO.. the above 3 make the biggest diff.
Some of the Hill Climb Racers ran over the engine steering on their IQ-RMKs which basically converted them to a quasi-IQR steering system with the severely canted steering post....
It also moved the rider position fwd about 6" (in this NON-Pro chassis style RMSHA racer "IQR" configuration, which has some plusses and many minuses on this chassis IMO.
If done right, you can get the benefit of the mechanism action of the Pro with a little weight loss. The airbox will probably need to be modded as well...but if you are turbo... not a big deal unless you run an intercooler.
