ok...so i got my pulley

ok...so on friday i bought my 3.4" supercharger pulley from a guy with a grand prix that found out he could do the 3.2" one and never installed the 3.4"
 
ok..so here's my question before i install it :)
 
can you install this thing without any programming??
 
what programming is needed??  i just heard people meantion that you have to reprogram it ...so i need to know what programming is needed...

good luck

I sat down with a rep from SLP for about 20min. last spring at the Lane Automotive show, and he said you can run a 3.4" or 3.5" without re-programming. BUT, you better run colder plugs and a high-flow 180 thermostat.  A 3.4" is worth what, 18hp?
I got about 60,000mi of warranty before I do that to mine.

ok...thanks for the info :)  i just needed to know if any programming was needed, glad to hear that not necesary....would programming benifit it if i did it though??
 
like i can install the pulley now and reprogram it later whn i have the moola to buy a programmer...or does it make that much of a difference to justify spending the 300 bucks on one...
 
18 hp for a pulley? thats a really nice gain..i was expecting something like that...thats definetely something you can feel :)

I just asked a co-worker who had a GP with a 3.2, and he said he had his reprogramed because of KR issues, but a 3.4 or 3.5 shouldn't be a problem. BUT, use the colder plugs, 180 thermostat, and ALWAYS use 93 octane gas. Cheap gas is what will get you.
He had DHP reprogram his PCM.

I have a friend who has a gtp that put on a 3.4 pulley and when he did this they guy said to also get the u-bend delete other wise there will be alot of back presure and i cant remeber if you have a u-bend delete or not so just something to look out after

I forgot about that, I agree.

i already have the exhaust completely done...first thing i did actually...still have stocker mufflers...and i also have a k&n cold air intake :)

Wow the misinformation that has been spreading since I left!!!
 
Just droping to a 3.5 can cause engine failure.  The first thing you need is a scanner of some form... I have a LS1M and it is one of the best investments ever.  I run 103 autolite plugs, 180* T-stat, Wizaired Cold Intake, Random Tech downpipe and Dynomax Catback, and 93 Octane.
 
If I floor it I get 7* of KR.    Anything over 5* is causing engine damage.
 
So first get the scanner, test, then install the pulley and test again.  I'm looking to actually swap out the whole system for a turbo this year.

i hope you know a turbo isnt going to solve your KR problem!  you may have a ls1m to scan with, but it cant do anythign to fix the problem.  if your getting 5-7* of Kr at WOT then you need to find out why.  could be a number of issues.  and if you had a programer you could atleast boost fuel in the section at wot where you are seeing the KR or lower the spark timing.
 
to answer the above questions... YES a tuner will make a noticable diff in HP.  you may beable to squeeze the 3.4 in and have no issues, but its not worth the risk.  get a tuner if you can afford one.... if you cant... get a scaner like the ls1m or the aeroforce interceptor ( what i have) 100-200 is better then rolling the dice and loosing the motor.
 
I personally have both a tuner and the interceptor.  many last year said i was crazy and it was overkill to have them both, but how many people want to drive around town with a laptop for everyone to see and steal?  i like to beable to monitor KR and my O2 readings while driving...  i spent a lot of money for the pair but i would do it all over agian. 
 
Yeah if you can afford the tuner get it first.  the sooner you get it, the sooner you can make the most out of the mods you have.  who knows you might not need another mod for a little while longer!  between fuel, spark, and shift point tuning, you can see some major improvements in 1/4 times.  not to mention you can adjust trany settings to protect it, and by having the fuel tuned properly you will save gas!

so by tuner you mean likea  superchips programmer?

By tuner I'm sure he means the DHP Tuner or HP Power Tuners.  You install the software on a laptop and plug it into your OBD2 port.  You can set air/fuel mixtures at different RPMs, and alot of other cool stuff.  Well worth the money in my opinion.
 
z34phoenix - Yeah, I know the turbo in itself won't fix the KR issue, but I do appreciate the post regarding it.  I know the KR problem is going to be heat related and I'm putting all my bet in the fact that the superchargers are known to create a tremendous amount of heat.  The supercharger might just need to be port and polished (I will probably get this done anyway) but by nature the tubos push cooler air into the system and I think that will help out the most in the end.
 
If it isn't, well then it gives me an excuse to have to get headers and port the heads.  :)
 

what happens if you dont have a laptop what do you do??

Then you need to buy a laptop.  You can get a ton of inexpensive ones on Ebay in the $100-$300 department.  Heck I'm looking to either sell mine or put it in the car only and it's only 4 years old.  It still makes a great every day pc (using it right now to answer) but I would like something faster for putting new games on.
 
All you need is a laptop made in the last 8 years or so to support the software.  I'd get one thats about 3-5 years old for the best price/performance point.  Mine is a 1.8 Ghz P4, 30 gig drive with 384 MB of memory.
 
The big point really to get on the laptop is to make sure it has good batteries so you can use it on the road.  You can always use an extention cord in the garage, but the porability is so much nicer.
