8 rib AC delete?

jivepepper · Dec 9, 2008

I know Riechard racing has an adjustable one but it's an arm and a leg.

I like the price of the Ford racing kit but they only come in a 6 rib. Is there another alternative or an 8 rib idler pulley that will fit on the ford racing bracket?

Thanks.

This is what I used on my 2000, which was just the stock 6 rib design but the only difference would be finding an 8 rib idler/tensioner pulley and modifing a tensioner arm to work like this.

If you wanted to keep the FRPP delete I'm sure there are alternate 8 rib pulleys you could use.

I can'I see the pic on the other site. If you are using a ribbed pulley on the tensioner. I can't do that because of the SC

if the AC delete has a 17mm mounting boss, then you could put most any idler there you wanted, including 8 rib pullies. Goodyear and Gates both have hundreds of different pulleys that fit a 17mm mounting boss.

Yeah it would take some re-engineering to figure it out with the SC on there. Just an idea.

How can I find the size of the mounting boss on the frpp kit? The last dufus I called there had know idea that there was even a need for an 8 rib AC delete.

I think I found something for 30.

Go to rockauto.com and look under the 2003 f150 Harley addition then under heating and air conditioning. It's listed as an AC bypass pulley.

On the 5.0s Ford had a bracket to move the PS pump up to the AC location and then you just run a shorter belt. Anything like that out there for the 4.6 yet ?

No there isn't. The AC and PS pump mount directly to the block/timing cover and have different bolt patterns. I'm sure something could be machined but it would be fairly involved and the amount of work to re-do the PS lines to reach to the other side of the engine would be pretty expensive and a pain in the ass.

But if it worked then you would have a shorter belt and that means free HP.

hey what size belt did u use when you deleted the A/c. I saw you use a 47" and it didnt work way to small?
