My car already idles at about 600rpm.. if i got underdrive pullies, will i be idling even lower or have a chance of stalling out? they look like a decent mod for the money, but not if i'm going to be stalling.

They won't affect your idle

it should not change...damn 600

mdvaldosta

I think factory is 650 on a 5sp

vfast

but 600 is awsum...

Its probably just the crappy tach not reading right. I set my tach needle up at 4k rpm according to the digital reading from the ecu, but at idle it reads 850 rpm when Im actually at 750 (higher because of the cams). Wonder why Autometer can make a good tach but Ford can't [&:]

it's called $$$$$ just think for every 10.00 it saves on a stang that means 100's of thousand of dolars of proffit

yea i idle around 750 RPM's, what kind of mods WOULD change your RPM's?

nanaki

did you see any noticable gain after putting them on?

reason i was asking about idling was i had a buddy who had a 5.0 liter stang that put some one and his car started stalling out. he had a sh!tload of stereo equipment in his car though. he said after he added pullies, if he was blasting his stereo, his car idle would go way down and stall.
