XRAY - Model racing cars

Got it,

Gonna try it on the 1st of april ( no Joke ) on an astro turf track in Purmerend. Tried the BBF Diffs and now gonna try stock, will let you all
now if the BBF are worth their money

Uur new track layout has a 150' straight with a nice wide bermed turn at the end. cant wait to go rippin thru there at 3/4 throttle.

It should stick like flypaper with the gearing change.

I am running 4 4 4 in my diffs with the overdrive gear.

What difference do you guys think there would be in the feel between 444 and 564?

rocco,

what brand oils do you run? do they make a 4 and 6? if not how do i go about getting the correct ratio to make a 4 or 6?

I don't think XRAY makes a 4 or a 6. They didn't with the old oils but I'm not so sure about the new oils.

Hey Rocco, wouldn't 6 in the center send more power to the rear than 4? It sounds like you are saying it backwards. From what I understand, the higher you go up in the center diff fluid, the more power is sent to the rear.

i would think that he might be doing that 'cuz of going with the 38t outdrive it would even it out. not 100% sure but that would be my thinking on it.

Whether you have the 38t or not doesn't change whether a higher center diff fluid will cause more power to go to the rear or more power to go to the front.

I'm just trying to compare 444 to 564.

Sorry yeah, more power to the rear, but the 5k in front is going to help it pull a little harder from the front...

I actually used old 3k in the diffs which in cps is about 43-4400.

But I do use the new oils, the select ones we did get from Xray...
