Pulley setup for eaton

[50hoes]

Hey guys just wanted some advice on the pulleys i should get, im ditching all the pulleys i have rn and getting brand new one because they are worn now i hate the squeaking noise so any advice on the under supercharger pulley maybe a lower? Stock eaton remember, other than that my cobra is a full bolton besides headers

I went with the billetflow pulley set. So far so good! I believe cobrabob has a section on his website with good information on pullies and belts that should be useful.

Stock eaton on pump gas? I would throw on a 2.76 upper with a stock lower along with some Metco double bearing idlers with the auxiliary idler an bracket and call it a day.

From what I've seen for a stock eaton stick with the stock lower. If it's ported get the 4lb lower.

Not too sure on 93 but when I was ported I had a 2.90 upper and 6lb lower and it was making 17psi on e85. After 15psi the eaton is pretty much being over spun and it will heat soak very quickly. E85 and the killer chiller I had was able to keep up but I never hot lapped it. A ported 2.76 upper only will make around 14psi.

Stock Eaton here with a Billetflow pulley set, they've been great so far. I've had them for close to a year now.

If it's not ported 2.76 upper stock lower, and either BF idlers, and a snub idler or metco.

if you do a bf you need a hub. they're about $60 used if you can find one.

you can but it'll get hot really fast. I had that combo on mine and it gets warm quick. spend some money on coolant mods, even with an AFCO, Reich 170 thermo, head coolant mod, and canton reservoir it still got hot. screams like a mofo and pulls but its gonna be hot.

2.9/2lb combo or just a 2.8 upper is a great combo and won't build to much heat. If you want to max out that non ported blower then you could run a 2.9 upper with a 4lb lower.

Thats the current setup i have rn 4lb lower and 2.9 but builds to much heat in this texas weather ima prob go with a 2.9 and 2lb lower now

Is there any measurable horsepower or quality difference between a metco 2.7 or billetflow 2.76?

 

[03cobra#694]

No

start looking for coolant mods or enjoy the heat soak.
