Default Looking for a kick in the ass in the right direction

Just about finished my build, planning on using the dunsford set up. I got an rx8 gen 2 and looking to hook it up to Tekin sc4 550 4.5 or thunder power 550 4.5. What kind of timing do I have to do to get this baby humming? Do I go with a 12t or higher for pinion? Plan on doing most of my racing at Hot Rods. I have put 5/5/3 in the diggs, what's recommended for shock oil? And any other tips u can throw in there, I'd most appreciate. U guys rock, the rc community is like no other. Thanks in advance.

Tekin suggested turning the can timing to zero and then run timing profile 4. Depending on your track size probably a 12 or 13. Shock oils i would run #3 pistons all the way around with 30 front 25 rear. Then dunford setup uses 575 the latest one does. If your building the kit do not use the kit oils as they are not correct.

I have torn it down and rechecked everything and it is assembled correctly.

It almost seems as if the diff case is too short and it is jamming the orbital gears up. If I loosen the cover screws up a bit it is smooth but of course then all of the diff fluid will leak out.

Will the gears perhaps free up after use or should I double the gasket to gain more clearance?
I had this issue with one of my cases. I switched it with another case and the problem was solved not sure if the case was warped or molded incorrectly.

It may seat with a little running. Sometimes the square spacers do not get fully seated and this can make the diff feel rough.

I would try the dunford setup fully. It has been a really good starting point in most conditions. We only really modify it when we run high bite blue groove (sugar or HRH dry track for big events ect.)

What I have noticed as the C rating goes up the mAh goes up along with the weight of the battery. While shopping for batteries I have seen the C rating as high as 100.
Has there been any independent comparisons on the batteries that anyone could refer me to?
Looking forward to hearing input.

Ken
SCTE is half way built doing a little bit at a time. Will have it ready for this weekend
Lol currently read up to post 5041 got about 1000 more lots of great info.
I would say for this car Higher C is better. Yes you are right typically higher C rating and higher Mah generally mean heavier battery. For the SCTE (or any 4wd SC for that matter) good batteries are important due to the massive amp draw these cars demand from batteries. We are not using the newer Venom 7000mah 70C packs which are only a few grams heavier then our 5800 70C batteries were. Extra runtime makes sure the 10 min mains are not a problem.

higher C rating typically means lower internal resistance so more punch and lower battery temps.

Venom batteries IMO are under rated for there "C" level compared to other batteries I have used or from feedback I have recieved from others who have tried my batteries. I have been VERY pleased with the performance and durability of the Venom packs and would highly recommned them to anyone looking for batteries. Not saying they are the only good batteries out there but I have had tremendous luck with my cells and cannot complain one bit about them.

Removed shocks and the front suspension is very floppy, no binding at all. I'm running Dunfords setup except for a different front kickup. 1 Front up 1 back down. I feel like it's coming from the 2mm of bump steer I have added like on Dunsfords setup. If I'm landing with the wheels turned could it be binding that way? I've tried to make it bind by hand and just can't do it. Any suggestion on where to look next?
I have seen similar problems when the nut retaining the top of the shock was too tight. Loosening it 1/4 of a turn solved the issue. Maybe if the little bushing and/or the shock standoff gets filled with dirt it can cause similar binding so cleaning them may help as well.

How does the setup fair on dusty,dry,no traction scenario?

Also. What is the difference in using the inner and outer hole on the metal TLR servo horn?

What pinion would you guys recommend for a RX8 with 4k pro4 motor?

Thanks.
