so, i would pretty much just want like the sts crank and alt kit?

stock is 2" diameter I believe and my asp pulley is 1" diameter, you still see a drop but I don't know much much difference with your 180amp and your system/compresser, however, there are other mods you can do before pulley

[xbrightsidex]

well, just ordered the sts pulleys. we'll see how well they do in about a month or so.

[DMP]

Anybody have a pic of the STS pulleys installed?

[zippplok]

how does this affect your motor when driving on the highway does the moter have to work harder to spin the small pulley spin twice as fast?
also where can i get some at for cheap? and all i need is two or can you make all of them smaller?

[Chris0nllyn]

geez dude, this has been answered a million times...it takes drag off the motor...

The alt pulley will INCREASE your amps. I have stock everything with these underdrive pulleys on my 2.2L and the biggest thing I noticed is my truck DOESN'T bog down when I turn the A/C on now.
I also noticed my lights flicker and my voltmeter is well above 15. I think the alt pulley is the reason I popped my low beam head HELLA headlight bulbs. I put stockers in and they work fine but I still see my interior lights flicker and if i look at it I see my radio doing the same.

ok whatever man. Just trying to tell you what I feel. Before I put them on turning the A/C on would make my truck bog down and turning it off would free it up and it was a noticeable difference. I also noticed I can pick up some speed going down the freeway at 65. Before I could try all I wanted and put my foot as far down as it would go and nothing seemed to give the truck speed besides a semi passing me.

haha thats cool dude...but theres no way it doesnt bog your truck anymore..you put on pullies, its not gonna make your truck NOT bog...plain and simple...any vehicle with a/c wil bog, its something else the motor has to turn so it will bog, maybe not as much....im not saying you dont get more power cause thats been proven already,,,glad you like em...everyones had all positive things to say about pullies...i guess thats the next thing on the list

[KENNYMO]

**** a/c just take it off. i noticed a lot of free'd up power when i did that.

[tstrenuous10]

well drive around here with no A/C on and let me know how the power is doing you then.

Next on my list is FLX-60 from summit racing. just went up another $5 in price today but it's supposed to be the best thing besides pullies. I have Al's header for a 2000 with air that I'm never going to install. Took it out of the bubble wrap and looked at it. then i put it back.

[Chris0nllyn]

someones look for an als header on here...its in his sig

[zippplok]

well i went and no onw had them so i hope napa has them or where can i get them online for cheap. the cheapest online i found was 165 plus shipping.

[What?]

I understand whatcha talking about with less bogging, its less noticeable

www.aspracing.com
www.truckperformance.com

More power=more money, if you can't afford, just save your $ and don't worry about it, you

for spending under $100 for 2 things to do

1. Efan(junkyard efan, autozone efan kit)
2. 56mmTB

I got efan for free + wiring kit of $30(adjustale stat kit)

56mmTB for $30

both are in sticky

ASP Pulley, mid-top end power, definitely worth the $ for me with mods, mpg increase was noticeable(5spd, reg cab, 98), but I notice more with little quicker rev

i think we misunderstood each other, i was asking about your TB spacer. (i DID write the sticky on the pullies )

i was asking if u noticed any more mpg gains from the throttle body spacer.

[Chris0nllyn]

no gains from the spacer

[comics22]

not even MPG? (its what im going for mostly, if it happens to make more toque and hp im all for that too)

[Chris0nllyn]

nope...

[comics22]

oh well. im happy with my mpg as it is (29mpg for my daily commute, 10 minutes of 55mph highway)

[What?]

hell no i dont have TB spacer lol, it make an excellent paperweight!

ill sell my set to you for $120 shipped, check out my ad in my sig for further info

[zippplok]

i went to advanced auto they say they dont sell a kit but if i know what size and which pulley they can find somthing that will fit.
so what pulleys do i need and what size (diameter) are they and how long is the belt?

[tsayyote]

I just finished my install. You can also use the Goodyear Gatorback 6pk1805 (if you have A/C AND are using the alt pulley) which is about 1/2" smaller than what is suggested in the write up. I used the 1805 and the tensioner looks like it is in the exact same spot as it was when I had the stock belt on there.

I'll snap a few pics tomorrow and post em up for the guys who were requesting pics, even though that was like 3 months ago.

[comics22]

yea ill throw a pic up. i love the Dayco Poly Cog belts tho.

[dngrous_dime]

Any of you that already bought the upgraded pullies, can you measure the OD at the contact points? (on the grooves)
Also, how much for your stock pullies, shipped to 49646?
I'm going to try and machine a set of my own from aluminum. Stock pullies, I need to measure the offset, bolt pattern, and actual OD to determine the % numbers for over/under drive.

[KENNYMO]

comic why did you put your crank pulley on backwards?

[GmcNoma95]

i dont think he put on backwards, think sum are solid manufactured like that instead of "hollowed out"!

GOT A QUESTION, i bought the ASP CRANK PULLEY, IM PRETTY SURE ITS THE CRANK "PERFORMANCE" Pulley from Performancecenter.com awhile ago...havent put it on yet...would i need to get a new "Aftermarket smaller alternator pulley aswell or no? And if so, where could i get a good one or a set other then the crank @.... ne websites?

Thanks

yea but if you look at his pictures of the pulley. you can see that it is a hallow one just like tha factory one.

and you dont NEED a alt pulley but it will help if you do. and you should be able to get one from the same place you got your crank pulley

if you got efan, over REAL 1000 watt amp/system, then yes, otherwise no


Thats not backward, thats the design of pulley

[KENNYMO]

check this pic out. i have the same pulleys but on my 4.3 and i installed it just like this. with the hallow side facing out.

[What?]

2.2l and 4.3l are different

is this the same 2.2L asp pulley u put on the 4.3l?

[KENNYMO]

no but mine look the exact same. and mine are the asp pulleys also.

[What?]

take em off, measure them and what not, i dont recall if crank are the same, the offset may be different as well

[KENNYMO]

no i know the cranks are prolly a different size and everything. im just saying mine looks the same as in one side is hallow like that. and i mounted mine the hallow side out cuz thats how the stock one is. and it worked just fine. so i figured that one was backwards

[What?]

yeah i understand what you saying, same thing for my 4.3L as well, would be nice if the 2.2L and 4.3l have crank interchangeable

[comics22]

if i did install it the other way theres no way in hell i could ever get the belt to line up

that and the big hole has a lip that fits perfectly in the harmonic balancer hole (just like the stock pulley)

[johnmyster]

Reccomendation: 71.5" belt (3" shorter than stock) for a 98+ using A/C and the ASP crank pulley. A 72" (2.5" shorter than stock) would be better, but they're twice the price at Auto Zone.

Go shorter for the Crank/Alternator combo pulley set.

[fozzy97noma]

If i order the pullie kit from truck performance do i have to purchase the alternator pulie somewhere else too? or does it come with it when u buy it from truckperformance.com.
