Looks like your exhaust will support it.Treys92 said:I'm thinking of stepping up to a 10% pulley. I currently have an early pulley on my home ported 94/95. What do you guys think i should do?? -Trey
I had the 1st. 10% avail. back in about '90. Everything stock, except the SC pulley. I could feel a difference. Course 2 yrs later I pd. the local German Ford garage $7,500. to put new head gaskets in my engine.xThunderbirdSCx said:I had an early style blower with a 10% and "classic" exhaust and made leaps and bounds in horsepower gains.
Nope, you got it backwards. The additional overdrive would be slightly LESS than 10%.Treys92 said:I had considered that also, but wouldn't my total overdrive be greater than 10% if i went that route? -Trey
It all depends on what supporting mods you have to go with the sc pulley. Every application is different. Maybe you didn't have the supporting mods on your late model, to go with a 10%. Other do have the supporting mods. So a blanket statment about what can & can't be run, is really misleading.JStudrawa said:I opened my exhaust with the age old 2.5-3-2.5 and was advised to run a 10% on my early model blower, but only a 5% on a late model or S-port.

The OD ratios are figured using the early pulley. The later M90 had a bigger SC pulley, which means that it moved slower than the earlier small pulley model. I think the late pulley is -3% from the early pulley. So with a SC 10% pulley on your late model blower, you'd be +13% from the late pulley.
The Stock arrangement overdrives the SC by 250%.
