What is a good start for gearing a 17.5 ramped in our buggies? (I have never ran 17.5)

I have a 13.5T and a 18T pinion. after 5 mins my temp is 120 if that

If you are doing a LOT of dynamic timing advance with a 17.5, I would start with 78/28. If you are doing NO esc timing at all, I would start with 78/32. Of course which motor, which esc, and what track you are on can change what you run.

No, I just want to use a nut to hold the wheel instead of that small screw that alwasy strips out.

I've seen this at my track a few years ago, but I don't know how to do it.

I run 27/72 with a moderate amount of boost. When I was near maxed out on boost (tekin rs), the car was FAST! Too much top end for my track. I'm down to 30 degrees advance now, from 50.

32/78 seems like a lot of teeth. Will that even fit? Low 30's on pinion is the right ballpark for unboosted stock though.

Anyone know where the +8 chassis is in stock?
thanks

I am using the strc one made for the SC10:

It is actually slightly narrower than the plastic one that AE sells for the b4.1.
I shimmed it and it works fine.

I would have never spent money to try it but one of my AE plastic ones broke on race day and I had the STRCs lying around. So I thought, "what the heck! Lets give it a go!" In any case, I finished 2nd in the A-main with them so I guess they're fine!

my local track

I saw them on ebay for 44.00 dollars

Anyone have an answer for this question??

it's the newer one with updated parts and its the one you should pick up at this time, either new or used.

The biggest differences between the two kits are the plastics used and the shocks. The B4.1 uses more flexible plastic than the carbon composite in the B4 FT kit. Also, the B4.1 has new V2 shocks which do away with the clip and spacer setup for the O rings in favor of a bottom loading cap for keeping the seals in place.

yes definitely go with the ft b4.1 youl end up spending less in the end because youl want to update your b4, trust me, i learned it the hard way

I bought mine from Superior. Ordered on Friday and got it on Monday.

Yes it will fit, and no, that isn't geared all that high for an unboosted 17.5. Some go as high as 34/75, which is too tall IMO. 32/78 is right down the middle.
