10 vs 8 rib???
Is it needed to use a 10 rib belt to make 1000rwhp with a ysi? I plan to use a direct drive and want to make 900 ish but undecided on 8 rib vs 10 rib. What are the differences in work trouble and costs involved?
Thanks
Rob

everyone told me 8 rib would do it... but i had to buy all the pulleys/crank pulley so why not just get the 10 rib? you will not have to worry about belt slip at all, i also run a DP direct drive.
cost wise, its not much more to go 10 rib. only thing different you need opposed to 8 rib is the brackets to move your steering rack forward about 1/4". arun sells everything needed.

With that said I agree with you, it's around the same amount to do a 10 rib setup. So do a 10 rib.

To say "not have to worry about belt slip" isn't necessarily true because even if you have a 10 rib and a direct drive there would come a point where your belt could slip. Honestly belts always slip a certain amount but there's a point of belt slip that you will not notice. With that said I agree with you, it's around the same amount to do a 10 rib setup. So do a 10 rib.
Thanks guys
Okay thats what I was thinking and it makes perfect sense. I thought it was more involved to do 10 rib so that is good. What pullies do I need I currently have an A&A kit so I need a 10 rib balancer and blower pullies is that it or some other pullies need to be 10 rib also?

Robert, get with Arun he can get you everything you need for the 10 rib conversion. When you do the direct drive the only 10 rib pulleys you will have are the crank, blower and tensioner and idler pulleys on the blower side.
The alternator pulley will stay a 6 rib with the direct drive.
If your doing the installation yourself make sure to later align everything or you will throw belts.

And relocate the PS rack, and find a 10 rib belt length you need, ect ect ect... If you slip with a 8 rib and DD, quit spraying WD40 on the belt.. I think balancer is more money as well.. 8 rib with DD took me to 26 psi.. but its on on yellow verts that it doesn't slip..

All the balancers from 6 8 or 10 are about the same price of $550 bucks new. Give or take a few bucks.
If he's doing the direct drive as he's stated, then belt size has to be calculated anyway.
I'm all for the 8 rib. I'm not saying it won't work for what the OP wants but if he can go 10 rib for the same or nearly the same price as an 8 rib setup then the choice seems simple
To the OP you have a YSi. If you go with a direct drive and a 10 rib I can let you know the belt size that I used.

. Just this pass week i went through 10gls of meth.
My meth turns on at 10psi. My last 8 rib went about 14k hard mile and i finally changed it when i was down to 6ribs left out of 8.
So far i have no reason to go 10 rib. Knock on wood. I read belt nightmares all the time on here.
So far so good if for some reason it starts ripping belts apart i'll hit arun for the 10 rib.

8 rib with a Dallas performance direct drive and. 2.6" pulley made over 1K on my car and never ate a belt with A&A brackets. Baby step the tension to get it tight enough and you'll be good.
I'm now on an 8 rib with Cartek brackets and F2. Regularly sees 25-30psi. Been on the same belt since March until I replaced when I had to change my ac compressor.....

Sounds like either of the 2 would work just fine for my goals. Thanks for all the replies and info guys now I am a little more in doubt of which to do. Sounds like the 10 rib is more insurance against slipping it is just a little more difficult to deal with but so far no reported issues with 8 rib slipping so that may be all that is needed.
