Default New 3.5 Pulley

The bearings in my snout went bad, so I stopped by INTENSE to get new one. Since I was getting a new snout, I figured, what the heck, I'll get a 3.4 modular pulley also. Well, they were out of the 3.4, so I got a 3.5.

Two questions:

1. After I put on the new 3.5 pulley, my belt keeps creeping to the middle of the new pulley. INTENSE told me to put the belt on the inside 6 ridges of the pulley, but it keeps creeping to the center 6. This causes the belt to ride on the outside 5 ridges of the main drive pulley (one rib of the belt is ridding off the pulley). What am I doing wrong here?

2. With the new smaller pulley, what other mods should I make? I know about the 180 deg thermostat, but what else should I do?

Did you also get a smaller belt, or are you using the original? Future mods - may want to start with Intense'* PCM. Have you opened the intake? High flow cat? If not, at least consider the intake along with the smaller pulley.

Edit - And a scan tool to check for any problems caused by your mods - in particular KR and timing.

I agree, you probably need the shorter belt.
First though, make sure you have the belt properly installed on all the other pulleys.

For the 3.5" pulley you can probably get by with gutting your stock airbox and using a K&N replacement panel filter, but considering how much the K&N replacement filter costs you will get more bang for your buck by getting the INTENSE FWI.
Also make sure your plugs are in good shape (might change to Autolite 605'* or maybe even 104'* if you are planning on more mods). A Magnaflow high flow cat would also serve you well. But that may require you to get an o2 simulator or if you are getting an Intense PCM have them eliminate that code.

I am using the stock belt (new - only 200 - 250 miles on it).

Stock belt is your problem , you need a 715 belt I believe.Also be careful if you dont have the other mods such as FWI, or PCM, plugs. Especially scan tool.If you have KR and dont know it , its not good. Better you didnt get the 3.4.

By the time I got home from work, the belt was almost completely off the pulley and was damaged pretty bad. I guess I will get the 715 belt. The INTENSE guys told me that the stock belt should work, but I guess in my case it did'nt.

I agree that it was probably best that I only got the 3.5 pulley (for now anyway).

INTENSE said that with the 3.5 I should be OK without any mods, but they suggested at least dropping to a colder plug and a 180 deg thermostat. I have already switched to a 180 deg thermostat. I was already running with NGK TR55 plugs, which is one heat range colder. Is that enough, or should I go with the TR6 or TR7?

How important is it for me to do any air box mods with just a 3.5 pulley?

I guess I will take it to a shop and get it scanned to check for KR. What else should I be looking for?

What does a decent scan tool cost? I just bought a code reader, now I guess I need to go up to a full scan tool (unless they cost too much).

Sorry for all the questions, but I am new to the mod game. . . . .

I ran a stock belt with my 3.4" pulley for awhile with no problems; I'm wondering if the SC pulley aligned correctly. And about the plugs you may want something a little colder like a TR6 I know the Tr55s seemed to burn a little hot for me with a 3.4. Maybe drive on those plugs for a little bit then pull them after 1k and see how they look.

TR55'* are fine. I'd probably gap them at .055" - Maybe someone else can back that up.

I thought other members here have been pullied and had stock air boxes - echossei I think?? A Fenderwell Intake will really make that supercharger scream though

Keep in mind you must scan for KR while the car is moving during Wide Open Throttle runs to see KR displayed. It'* not something a scan tool will pick up after the fact.

The Aeroforce is $240 but it displays 2 parameters at a time, almost 30 of them to choose from, and is constantly running while your car is on. It'* nice to have all the info at your fingertips. It also reads codes of course. It mounts cleanly in your dash too.

I think he should go smaller then that. Intense says .050 for 6-12lbs of boost without NO2.

Yeah many have been pullied with a stock gutted air box. I ran a 3.4" for over a year with one. Billboost even ran a 3.2" on a stock air box for a little bit if I recall. But I did notice quite a difference with my FWI with a 3.4" whether it was from the cooler air and/or better flow I don't know but it works. Not to mention it is much louder and easier to scare people on the sidewalk now

At Todd'* (Rogue) recommendation, I am running Autolite 605s with a gap around .057 with my 3.4.
