Installed ASP underdrive pullies today

red95gtconvert · Feb 6, 2007

UPS delivered my ASP aluminum underdrive pullies today and since in was nice out (65*) I decided to install them today. The install didn't take to long, probably because I didn't install the alternator pulley because I didn't want charging issues. After putting them on I took the car out a to nice backroad that could almost be used as a sanctioned road race course to see if they made a difference, all I can say is wow they woke my car up alot. The car revs up stronger and smoother and has a more powerful feel to it. No regrets on this mod

Did you have to switch belts since you didn't use them all?

red95gtconvert · Feb 6, 2007

Nope, I was able to reuse the stock size belt.

Danman765432 · Feb 6, 2007

You will still have charging problems even with the stock alternator pulley

red95gtconvert · Feb 6, 2007

Hmmm, I turned on the lights and everthing else on the car and at idle the volt guage reads right where it did before the pullies were installed

when the car warms up you will notice it to slowly go down...also watch out in the summer they could cause overheating problems too, that is why I am putting my stock ones back on....but they do really wake up the car.

When you have the A/C On too it will drain it a little faster. Just make sure to watch out for it. If your radio cuts off, give it some gas right away so it dosent die. I had to do that alot with mine.

I don't have any problems at all with all three of my ASP pulleys in place?? I don't have any kind of fancy sound system though. My battery is about two years old.

I LOVED this mod.

I ordered an ASP overdrive alternator pulley tonight just for the piece of mind, I don't like dimming lights or my car cutting out

i know i soooo regret doing underdrives on my 93 it is bad in that car..and as mentioned as you drive it goes lower ...and there is no charging at idle....totally sucks...

however the alternator in a 93 is much lower amp rating then what was installed in a 94 i believe the 93 had a 65a..? and 94 was a 100a...? maybe im wrong...i would like to do underdrives on the 94 but i see a lot of people having issues so it scares me and i feel its crapy to buy a pulley kit and not use all the pullies so i might stick with stock pullies until i get some solid evidence of the charging issues

You can make a significant difference on the amount of juice your
alt cranks out with just a couple of hundred rpm.

On a stocker or bolt on Stang ................
Peeps have no need for a higher idle
hence
You see them cry about ud pullies

H/C/I combos usually need an idle rpm of 800 to 900 rpm which
can give that advantage of extra juice from the alt

I got em on my 95 with no problems

Free rwtq ALL across the ENTIRE power band

The kinda deal .......... I just ain't gonna pass up

Install the alternator pulley, you won't have any issues

That's exactly why I don't have any problems. I have mine idleing at 750. It just seemed like more of a happy place and helped with some driveability. That must be the difference maker right there.

I didn't even think of that being why I don't have any problems.

Do you get any overheating problems in the summer?

vp6799 · Feb 7, 2007

I installed MAC underdrive pullies and I have no problem. It idles at about 800 rpm's. No charging or overheating problems. Best cheap mod that I did.

No, I don't.

With that being said, I have used the TwEECer to kick on my fans slightly before the stock setting and I run a 180 degree thermostat.

That is the thing to keep in mind about our hobby.

We all got a Stang
but
Our expectations or goals for it
determines
Our application of how we use it
thus
It is not ALWAYS a black or white answer we can give others
when they ask for help, advise, or info.

I have often thought .......
Ya'll get tired of me seeming to focus
a lot of my replies around that phrase ........... it depends upon

anyway .......

You gotta admit it
If you pay attention
You can learn good stuff on these boards
I know I learn from you guys every day

Wish I had an internet when I got started in this hobby
