what pulley could i use 2 brind my rpm down @ highway speeds 70mph = 3100 rpm im runnin a s/c with stock pulley!!! please help

 

You cant..... That would be your transmission. You would need to change either your Overdrive gear ratio, or the final ratio.

 

funny what the price of gas will make people ask...

or is it for some other reason?

 

 

haha no kidding right!?

 

you can kill v8's with your sc?

 

This is true. Changing your pulley diameters will only affect the roational speed of the serpentine belt and perhaps free up 1-2 horsepower. I suppose if you really wanted to lower your highway rpms you could run a taller tire, but you'll also kill your bottom end performance.

 

well i was thinkin it was gonna be tha trans but oh well an yea i can beat v8s

 

^ what v8's can you beat with the TRD supercharger? I'm curious to know as I have the Supercharger too...

 

^ mustang gt is a popular one

 

lol yea the gt is an easy kill

 

i wanna see proof of this... especially if you have a stock supercharger.

 

the previous model gt's are more likely..the new gt's run 13s stock.

 

i was going to say that. When i was running what I have now but w/ stock boost i was dead even with one at a stoplight ....and that was one from around 2000 - the newer ones are a lot quicker.

 

well im not just boosten im also runnin a 75 shot of spray and a greddy full e-manage with 6 hrs tune time

 

oh such an insignificant detail..wouldnt make a difference at all!

ever tracked it yet? and how much power are you making?

 

if i would have known that, i wouldn't have questioned you beating v8's...
