Question, I see that some are saying the new pulleys increase acceleration, is this true or just speculation??? From what I understand the new pulleys lower the internal gear ratio to 1.77 from 2.125 which would make me think acceleration would decrease. Is this increase in acceleration, despite the lower internal gear ratio, due to the drive train having less friction???

So using the 1.77 gear ratio, you're still looking for a 6.9 to 7.5 depending on the track for a monster stock correct? Say I run a 120/35 with the 2.125, that gives me a 7.29, to get the same ratio for the 1.77 I would have to run a 120/29 roughly. Changing to the smaller pinion results in the faster acceleration if I am correct on my theory.

Cypress-I will most likely go again tomorrow. Maybe bring two charged packs this time!!! hahaha!!!
I will report findings when I can get some consistent data and laptimes!!! I knew I was in trouble when I went around a fast corner lifted for the next one and spun out!!! But the tracks a new layout and it hasnt been run on in a week. It hasnt formed a groove yet.

Also Get:
-C-hubs left and right in 3 and 6 degrees. get 2 per side for the 6 degree and 1 per side on the 3 degree.
-Buy the #300900 composite C-hub kit.
-Front adjustible sway bar or the new wire front sway bars.
-Buy any top decks that fit your needs. If outdoors, stock may be fine, but if carpet/foams your bag baby, get the solid top deck.
That should do it. Cars pretty tough and the #300900 kits got a lot of parts in ti your likely to bend or break.

Or if on asphalt, the composite is fine and inexpensive to replace. But they will break or snap once you hard kissed the board. I would definately suggest stocking an couple of extra C-hub blocks and maybe a knuckle or two.

Most of all, keep in touch!
Everyone else on this thread, Ray, RCZombies, Neil and the other great Xray folks, my hats off to you too for all kinds of good information! It only gets better..

Thank you for the compliment. You're making me blush now. I try to do my share and because of racers like you, it is more than worthwhile for me and other R&D developers to constantly test and try new methods. I will definately keep in touch!

Yes, the actuals would be 120/29=7.32 final ratio. The only difference is that your acceleration would be quicker due to the lower internal gear ratio. So say in a standing start in the beginning of an A-Main, you're chances of getting out in front is much faster then you were with the old ratio. Hope this helps.

I am so hyped on running this car.
Thanks for your guys help.My evo3 was nice but I did not like having to wrench on the front for a little board slap.I keep seeing that this car is not hype but an excellent car,even though its not a shaft.Who knows,if xray decides to go that way,if they make me happy now I will be loyal if they ever jump on that band wagon.Ok I need particulars.
Buy the Composite Conversion kit.
Rear roll center bridge
What about the New pullies?Yeah or neah?
Front blade sway bar.
What about when carpet season comes around?What parts will I specifically need?Also what about the aluminum shock bodies?
Or are the plastics just fine?IS the Spring kit worth the investment also.Thanks again!

Buy the Composite Conversion kit. Yes
Rear roll center bridge. Yes
What about the New pullies?Yeah or neah? Yes, but practice with the old one first.
Front blade sway bar. No..get the new wire front say bar kit..soon to be released.
What about when carpet season comes around?What parts will I specifically need? don't know..haven't race carpet yet...possibly the stiffer upperdeck.
Also what about the aluminum shock bodies?
Or are the plastics just fine?Yes/no..plastic ones work fine..aluminum ones are for looks..even thou I have them..hehehehehe
IS the Spring kit worth the investment also. Yes, but I find that I don't use all of them. After you find a set-up that works consistanly...you may end up not using the rest.
Other stuff... replace the stock shock bladders with GS Silicone bladders...they will leak less and get better rebound...
