What are some good pulleys to put on my 91 3.1 rs? After the holidays im gunna be adding a chip, dynomax catback, and maybe pulleys if they aren't super expensive

 

ASP pulleys....been running their two pulley set for 2 years now

 

hey SAEspinz,
have you ever had an electrical problem after installing the pulleys? there is a guy on the firebirdv6 forums that had a ton of problems after throwing some pulleys on his '91.
also, how does that aerochamber sound on ur v6? i have a flowmaster 80 on my 3.1, and as everyone knows, they get ***** in the higher rpm's. people have been fooled into thinking mine is a v8 when i just cruise by, and in my opinion, it sounds awesome in the lower rpm's. how is yours?

 

I have pullys on all 3 of my rides. The first set was from jetchip.com, the other 2 are from aspracing.com

No problems so far.

 

I run a 200amp alternator on mine with both pulleys for good charge. Stock alt with the lights on at idle or the a/c on at idle read a discharge and was drawing too much power from everything. G()d help me if I ran the lights and a/c at the same time, even now with the larger alt this will still cause a slight problem

 

what do pulleys do exactally?
and is there any negatives?

i was looken at some from jetchip as well as the stage 2 chip

 

someone said a while back that the alt pully in asp kit made it so the alt did put out much power untill 1100-1500rpm


So I wold guess if your car idles at 800 rpm and you dont drive very far or fast, after a while you will kill your battery.

I

 

my car idles 1k+

 

It slows the spinning of other items. It reduces the "drag" of them.

My show truck has the dual pully system, I can run lights, defrost, and radio and have no problems tell I hit a loud deep base note, then that lights dim.

My two daily drives have them, no affects at all. Yes, the crank only pully brings the charge rpm to like 900 or so?? Big deal, car idles at 1000.

The dual pully system is 1100-1200 something like that. aspracing.com has all specs listed on their site.

 

whats a good one to get with the most gain and least adverse affects?

my lights dim alot now because im running my stero with no cap yet

cap soon

 

the only onesi see on ASP racing is

88-92 305, 350 25% Crank 800 RPM ASP540800
$74.95

88-92 305, 350 25% Crank
23% Alternator 950 RPM ASP540801
$94.95


my cars a 3.1...so those wont work wil they

 

I got my pullys from PAW they are amde by HyperTech i belive and cost me 54.00 You will get a nice gain in power and in gasmilage.

 

must have been blind

88-95 2.8, 3.1, 3.4 25% Crank
23% Alternator 1100 RPM ASP541801
$84.95


Those the right ones?

 

If go with the ASP's buy them from Summit Racing. ASP charges all most $40 more. I bought my ASP's from Summit and only paid $54 + S&H.

 

mmm

ASP crank pully
or ASP crank and alt pully?

With using the alt pully alot of ppl have problems with it am I correct?

So
ASP crank pully
or Jet pulleys?

 

ANy Pully will work all the same basicly. I just used my crank pully i used the alt pully and my car batt would aways be dead when i got outta school since then ive had no problem after i took the alt pully off. I even had a 140 amp alternator on my car.

 

Hey....ok, lets start with the pulleys. I have been running dual ASP pulleys for almost 3 years now. With no adverse effects at all. At 87,000 miles my stock alt went...so I replaced it with a new STOCK alt. Left all the pulleys on. Since then (115,000) I haven't had anything go wrong with the car electrically or charging wise at all. I have been running the same Die Hard Gold battery for 3 years as well. However, you WILL notice the following: At night your headlights and interior lights will dim slightly at idle. Your voltometer will drop a bit too, but once you start cruising all is good and I show a strong 13-15 volts. Now, with my headlights, fog lights, wipers, AC, and radar dectector all on....occasionally my radar dectector will flash "low voltage" as the wipers move (it is hard wired into the car). And then stop when it stops. No biggie really! So NOPE....no problems here that are adversely affecting performance or daily driving (it is my daily driver).

As for the Aero-Chamber muffler. I couldn't be happier. The best way for my to describe it is throaty. Nice and deep too. It has a great rumble at idle....and you get on it and it really open up, and not obnoxiously loud (it still turns head though). Internal resonance is perfect too. Not too loud (easy to talk to girls in the car at night) but you know its there. And as you get up the RPM range it definately gets louder, never sounding ***** at all. Maybe the only time it does is first thing in the morning when the system is cold. It tends to pop a bit up near 5,000 rpms. But once it warms up it dissappears. So all and all its great! Great sound. I have a sound clip. I can email it to you, it varys from idle - 4500ish. You will notice a little popping. Again the system was cold....but even cold it won't start doing it untill about 4500 rpms. Once warm it goes away. It was exactly the sound I was looking for.
